The astronaut wears Prada as Axiom unveils new spacesuit

ROME — Astronauts walking on the moon as part of NASA's first human mission to the lunar South Pole will be wearing Prada, as part of a new venture unveiled on Wednesday.

Private space company Axiom Space teamed up with the Italian luxury brand to provide the surface suits and spacewalk systems for NASA's Artemis 3 mission, which is planned for September 2026.

The external layer of the space suit, designed to reflect heat, is largely white, as it was on the suits worn by the Apollo astronauts who last walked on the moon more than 50 years ago.

But the update will have a few touches of grey and some red stripes similar to those seen on Italy's Luna Rossa America's Cup boat, which was also sponsored by Prada.

Matt Ondler, president of Axiom Space, told a press launch in Milan that making the suit had required "extreme engineering" and "fantastic manufacturing capability".

"They will go in places that are incredibly hazardous, extreme environments," he said.

"One of the missions that NASA wants to do is to try to find water craters at the South Pole. These are some of the coldest places in the universe. And so this suit has to be designed very cleverly."

At the lunar South Pole, a land of mountains and deep craters, the sun hovers below or just above the horizon.

As a result, temperatures vary from upwards of 54ºC in sunlit periods to -203ºC in shadowed areas that have never see the sun, NASA says.

The suit aims to provide maximum comfort to the astronauts, the team said, while also protecting them against radiation, external pressure and provide the power and oxygen they need for up to eight hours of moonwalks.

With the mission set to see the first woman on the moon, the suits are also unisex and can be adapted to different sizes.

"We've blended engineering, science and art to produce the ultimate garments for future moonwalkers, ensuring that astronauts can perform their tasks and missions in safety and comfort," said Russell Ralston, Axiom spacesuit programme manager.

The design of the boots was a particular challenge, in terms of insulation and to make them robust enough for the terrain.

But the materials used are "confidential", said Lorenzo Bertelli, marketing manager for Prada and the son of the fashion house's founder, Miuccia Prada.

In the Colombian Pacific, fighting to save sharks

ISLA DE MALPELO, Colombia — A lone catamaran named “Silky” patrols waters around the remote island of Malpelo, a refuge that is protected yet full of peril for endangered marine species in the Colombian Pacific.

Its crew of environmentalists is the terror of boats illegally fishing for sharks inside the reserve some 500 kilometres off mainland Colombia — one of the richest countries in terms of marine fauna.

Without weapons or backup, the activists shoo away intruder vessels, threaten to report them to the authorities, even dive under water to cut loose sharks caught in nets or on lines.

Active round-the-clock since 2018, the team of shark-lovers claims to be turning the tide in the Malpelo Fauna and Flora Sanctuary, a mecca for divers and the largest no-fishing zone in the Eastern Tropical Pacific.

“The success of the project can be seen in the fact that they [the illegal fishers] do not return,” said Colombian diver Erika Lopez, who created the foundation Biodiversity Conservation Colombia with the help of an Australian philanthropist.

The project was born from what the activists view as a lack of official shark protection, with the navy arresting illegal fishers only if they happen to come across them on routine patrols against drug traffickers and other territorial intruders.

Due to play host of the UN COP16 biodiversity conference starting next Monday, Colombia’s vast Pacific coastline is on a key migratory route for hammerhead sharks, whale sharks and other species, many of them endangered.

But the bountiful waters of the sanctuary attract vessels from far and wide, many from neighboring Ecuador, others from Panama and Costa Rica in the Caribbean or even China, where shark fin is a delicacy.

Lopez’s foundation claims the crew of the Silky — the name of a type of shark — has rescued 508 animals alive since 2018, scared away 302 boats and confiscated more than 70,000 meters of fishing line.

Since last December, the foundation reports it has not spotted any fishing boats near Malpelo island in the reserve of more than 850,000 hectares recognised as a UNESCO heritage site.

“We try as much as possible to take the equipment away from them, to free the species that are trapped, that’s the main mission,” 53-year-old Dario Ortiz, an artisanal fisherman-turned-environmentalist, told AFP on board the “Silky.”

“This boat has to be basically 24/7, 365 days a year containing this threat,” said Lopez, 51, who dreams of upscaling the project to a flotilla of vessels dedicated to conservation and science in the Pacific.

 

Rich and desirable

 

On the high seas, far from Malpelo Island, a Colombian navy warship also patrols an area teeming with hammerhead sharks, marlin and other endangered creatures.

On a recent mission with AFP on board, it arrested three Ecuadoran fishermen found with a highly valuable haul of silky, hammerhead and blacktip sharks, sailfish and four blue marlins — all still alive.

“The Colombian Pacific is very rich and it is desirable,” said Admiral Rafael Aranguren.

With “our ships we can reach this part of the territory and exercise controls so that they do not illegally exploit these riches, so that they do not harm the environment”.

In 2020, the government of former president Ivan Duque banned shark fishing, both on an industrial and small-scale, to try to protect marine stocks.

But faced with an outcry from Afro-Caribbean fishing communities on the Pacific coast which rely on shark catches for meat to eat and sell, incumbent President Gustavo Petro in January partly repealed the ban.

The government decreed that small-scale fishermen may keep and consume sharks accidentally caught in nets meant for other, unrestricted, fish species.

The decision caused outrage among conservationists who view it as a licence to kill.

The Navy estimates it has arrested 30 people so far this year for illegal fishing in Colombian waters.

Between 2012 and 2022, authorities seized more than 334 tons of fish meat illegally harvested, according to the ministry of environment.

The country does not keep a record of sharks that fall victim to illegal fishing.

Coffee & oral health

Drinking coffee can feel great and help you feel energised for the day. However, this is a false feeling and what’s more, your teeth and gum health are at risk too.

Did you know that by drinking only one cup of coffee a day, you can increase your chances of cavities?

Teeth discolouration

Coffee can also contribute bad breath because it increases oral bacteria in the mouth. The bacteria creates acid that leads to tooth and enamel erosion.

Enamel is made up of minerals, mainly hydroxyapatite. It is the protective layer on your teeth. It’s also partially responsible for their colour.

The most prominent problem of drinking coffee regularly is the discoloration of your teeth.

Coffee can discolour teeth because of an ingredient called tannin found in other beverages like wine and tea.

The enamel combined with the colour of the underlying material of dentin produce the coluor of your teeth.

Coffee can penetrate enamel, covering it with a deep yellow to brownish tone.

Coffee creamers and sugar

When the enamel becomes thin, the dentin becomes more visible, resulting in yellow teeth.

Adding creamer to coffee will also not hinder the discolouration of your teeth.

The pigments and acids responsible for the dark coffee colour don’t disappear by adding creamer, so it can still stain your teeth.

Creamer and sugars can also speed up the growth of bacteria.

Straws

Although stopping your coffee consumption would reduce your chances of discoloring your teeth and damaging your dental hygiene, stopping your coffee intake can be difficult.

To avoid the discolouration of your teeth, you can try drinking it from an environment-friendly stainless steel straw to reduce contact with your teeth.

You can also try to sip coffee throughout the day, rather than drinking it in one go to prevent the build-up of bacteria.

Drinking lots of water can also help quickly rinse the residual liquids.

Brushing your teeth

One of the most effective ways to help reduce the effects of coffee stains on your teeth is by thoroughly brushing and flossing your teeth shortly after a cup of coffee.

Vegetables

I recommend waiting at least 30 minutes after drinking coffee to brush as it will allow the acid in your mouth to neutralise. Eating vegetables such as carrots and celery after a cup of coffee will help in reducing tooth discolouration and freshen up your breath.

It’s also a great idea to see your dentist at least once a year to deep clean your teeth.

Your dentist can help clean the stains from your teeth so your smile stays nice and pearly white!

Keeping your teeth white

There are a few ways that you can help maintain your dental hygiene, including:

-Waiting 30 minutes before brushing your teeth.

-Drinking water.

-Using a stainless steel straw.

-Getting your teeth professionally whitened.

-Visiting your dentist regularly.

-Brushing, flossing and using mouthwash regularly.

Musk's X available again in Brazil after 40-day ban

RIO DE JANEIRO — Elon Musk's social media platform X, which was banned in Brazil for 40 days in a legal tussle over disinformation, was available again in Latin America's biggest country on Wednesday.

The site was accessible from inside Brazil, also the largest Latin American market for X, a day after the Supreme Court lifted its suspension.

Users reacted enthusiastically to its return with the hashtag "#voltou" (I'm back) trending in Brazil.

The network also welcomed the decision.

"X is proud to return to Brazil," it said on its global government affairs account, adding that it would "continue to defend freedom of speech, within the boundaries of the law, everywhere we operate."

Musk himself had yet to publicly react.

The reactivation appeared to be taking place sporadically, with some users still failing to connect to X.

Brazil's telecoms regulator Anatel explained that the delays experienced by some were due to the workings of their internet providers.

X had 22 million users in Brazil before it was blocked on August 30 by supreme court judge Alexandre de Moraes for failing to comply with a series of court orders aimed at combatting disinformation.

Moraes authorised it to resume activities on Tuesday after X paid millions of dollars in fines.

The company also eventually complied with his other demands, including that it deactivate the accounts of several supporters of far-right ex-president Jair Bolsonaro who were accused of spreading disinformation and that it appoint a legal representative in Brazil.

'Brazil is sovereign' 

Communications Minister Juscelino Filho called the outcome a "triumph" for Brazil.

"We have shown the world that here you have to respect the law, whoever you are. Brazil is sovereign," he said in a statement.

The showdown between the powerful judge and Musk -- the world's richest man, who has been accused of allowing hate speech and disinformation to proliferate on the site formerly known as Twitter -- was closely watched around the world.

Musk had lashed out at Moraes over the ban, calling him an "evil dictator" and dubbing him "Voldemort," after the villain from the "Harry Potter" series.

Geoffrey Hinton, soft-spoken godfather of AI

PARIS — For a brief moment in spring last year, the bird-like features of bespectacled British-born researcher Geoffrey Hinton were poking out from TV screens across the world.
Hinton, a big name in the world of artificial intelligence but largely unknown outside it, was warning that the technology he had helped to create -- for which he was awarded the 2024 Nobel Prize -- could pose an existential threat to humanity.
"What do you think the chances are of AI wiping out humanity," a reporter from the US network CBS News asked in March last year.
 
"It's not inconceivable," replied Hinton, making a very British understatement.
 
A few weeks later, he had walked away from his job at Google and was giving interviews to media across the world, quickly becoming the poster-child for AI doomsayers.
 
Difficult family life
 
Hinton, a 76-year-old soft-spoken career academic, was born in London, raised in Bristol and went to the universities of Cambridge and Edinburgh.
 
He has described his early life as a high pressure existence, trying to live up to the expectations of a family with an illustrious history, littered with storied scientists.
 
Even his father was a member of the Royal Society.
 
He told Toronto Life magazine he had struggled with depression his whole life and work was a way of releasing the pressure.
But Hinton has rarely been able to fully escape into his work.
 
His first wife died from cancer shortly after the couple had adopted their two children in the early 1990s, thrusting him into the role of single parent.
 
"I cannot imagine how a woman with children can have an academic career," he told Toronto Life.
"I'm used to being able to spend my time just thinking about ideas... But with small kids, it's just not on."
 
'Utterly correct'
 
After spending time in universities in the United States in the late 1970s and 1980s, Hinton relocated to Toronto in 1987, his base ever since.
 
Hinton, a self-professed socialist who recalls his family stuffing envelopes for the British Labour Party, had been unwilling to accept funding from the US military, which was the biggest funder for his kind of research.
The Canadian government agreed to back his research, which attempted to replicate the functioning of the human brain by engineering artificial "neural networks".
 
Although he spent years on the academic fringes, a research community grew up around him in the Canadian city, and eventually his vision came to dominate the field.
 
And then Google came knocking.
 
He took a job with the Silicon Valley juggernaut in 2013 and suddenly became one of the central figures in the emerging industry.
 
As competition ramped up, many of his students took posts in companies including Meta, Apple and Uber.
Ilya Sutskever, who founded OpenAI, worked in Hinton's team for years and has described the time as "critical" for his career.
 
He told Toronto University's website in 2017 they pursued "ideas that were both highly unappreciated by most scientists, yet turned out to be utterly correct".
 
But Sutskever and Hinton have emerged as prominent worriers about the technology -- Sutskever was pushed out of OpenAI for raising concerns about their products a year after Hinton exited Google.
 
And true to form, even during his acceptance speech for the Nobel Prize -- he received the news in a "cheap hotel in California" -- Hinton was still talking of regret rather than success.
 
"In the same circumstances, I would do the same again," he said.
 
"But I am worried that the overall consequence of this might be systems more intelligent than us that eventually take control."
 

Grammy-winning Cissy Houston, mother of Whitney, dies at 91

By - Oct 09,2024 - Last updated at Oct 09,2024

NEW YORK — Cissy Houston, the Grammy-winning mother of the late Whitney Houston, has died, her daughter-in-law said in a statement Monday. She was 91 years old.

"It saddens my heart to announce the passing of my beloved Queen Cissy Houston today! Please keep the Houston family in your prayers," Pat Houston wrote on Instagram.



Born Emily Drinkard, Cissy Houston sang soul and gospel, boasting a successful backup career for the likes of Elvis Presley, Aretha Franklin and Dionne Warwick, including as part of the popular group the Sweet Inspirations.

Along with being Whitney Houston's mother, she was the aunt of singers Dionne Warwick and Dee Dee Warwick, and a cousin to famed opera singer Leontyne Price.

A popular session singer, Cissy Houston recorded hundreds of songs across the genres, with her vocals included on tracks by stars from Jimi Hendrix to Beyonce.

As a gospel soloist she nabbed Grammys for the albums "Face to Face" and "He Leadeth Me" in the late 1990s.



Her daughter Whitney is one of the best-selling US musical artists of all time, with classic hits showcasing her remarkable vocals including "I Wanna Dance With Somebody (Who Loves Me)" and "I Will Always Love You".

Whitney Houston died in a shock drowning the day before the Grammy awards in 2012, at age 48.

Restoration experts piece together silent Sherlock Holmes mystery

BERKHAMSTED, United Kingdom — Sherlock Holmes fans are being promised a most authentic depiction of the fictional detective, with the restoration of a century-old silent film series chronicling the London sleuth's adventures.

Audiences will be treated to a first glimpse of the restored works from the early 1920s next week at a London Film Festival screening, accompanied by a newly commissioned live score from Royal Academy of Music performers.

The October 16 premiere of just three of the short films, in what is being called "Silent Sherlock: Three Classic Cases", will take place in the Victorian-era grandeur of the Alexandra Palace Theatre in north London.

A wider release on DVD and Blu-Ray, and encompassing an international tour, will then follow, with the British Film Institute (BFI) restoration team excited to unveil its years-long efforts.

"They're the last silent Sherlock-related works to be restored," explained Bryony Dixon, the BFI curator who led the project.

"The other surviving ones have already been done, so these are the things that audiences have been waiting for patiently," she told AFP at the film charity's national archive in Berkhamsted, northwest of the UK capital.

"Sherlock Holmes is always popular, and popular all over the world. As they say: you could just write Sherlock Holmes on a cardboard box and sell it.

"So it's of interest to people and it's time that it was seen."

'Authenticity' 

Produced in 1921-23 by British film company Stoll Pictures, the 45 episodes of "The Adventures of Sherlock Holmes" and two feature films that are being restored all feature screen star of the era Eille Norwood.

He was author Arthur Conan Doyle's favourite on-screen Sherlock.

Conan Doyle's creation has been adapted for the big and small screen hundreds of times, with Guinness World Records hailing him the most portrayed literary human character in film and television history.

Famous faces to have played Sherlock recently include Robert Downey Jr and Benedict Cumberbatch.

But Stoll's black-and-white adaptations were made with the author's approval while he was still penning the stories, setting them apart, according to Dixon.

"People will be interested to see a Sherlock Holmes film version... in an early stage of development for the screen," she said.

"There is a level of authenticity to this character, vis-a-vis the Conan Doyle creation, that you might not get with later Sherlock Holmes."

 

Time-consuming 

 

Restoring the more than 20 hours of footage -- funded through an initiative of data storage and management firm Iron Mountain -- began in 2019 at the BFI's vast archive.

The repository, on a former farm, houses hundreds of thousands of reels dating back decades that are stacked on lofty rows of shelves in refrigerated vaults.

Particularly old footage on nitrate film -- like the Stoll series -- are also kept at another, even colder, site in western England but brought to Berkhamsted for restoration.

Conservators in white laboratory coats have spent months meticulously checking and cleaning reels of original negatives and copies.

Some were damaged, requiring painstaking repair.

"Despite all the damage, it is in pretty good condition," said senior conservator Kirsty Shanks, noting that old reels can arrive decomposed into "powdery, sticky, solid messes".

Many of the Sherlock nitrate prints were mouldy, oily, brittle and fragile, requiring time-consuming cleaning by hand, she added.

Another challenge has been negatives arriving in sections, rather than complete reels, requiring staff to sequence them.

'Special' 

Down a corridor lined with vintage movie posters and old film equipment on display, Ben Thompson has spent hundreds of hours in a windowless room, working on the endeavour.

The image quality lead has had to ensure the new digital version replicates the 1920s footage in texture, colour palette and other aspects.

He uses software to match the original filmmakers' use of colour tinges -- primarily blue and amber dyes -- to parts of the negatives to help denote night, day and flashbacks.

Thompson also has a hand in repairs, noting the beginning and end of reels have often borne the brunt of past use and require the most intensive rehabilitation.

"It's the starts and ends where you get into the real manual work," he explained.

He recounted working for days on a single 10-second opening shot of Sherlock's Baker Street home neighbourhood. In comparison, some mid-reel scenes required just minutes of repair.

BFI veteran Shanks described the project as the most "challenging" restoration of her career but still a labour of love.

Paris fashion: Feathers fly at Chanel as Vuitton packs in stars

PARIS — Chanel returned to the Grand Palais — scene of the late Karl Lagerfeld's most legendary triumphs — for the first time in four years on Tuesday, without a designer but still able to ruffle feathers with its birdcage-themed Paris Fashion Week show.

The famed French house turned the refurbished Belle Epoque edifice into a giant aviary, with a white birdcage at its centre to show off a collection festooned with plumes and feathers.

Only a day earlier, British designer Stella McCartney had lamented the "billions of birds killed for the fashion industry" after the animal rights campaigner's own bird-themed Paris show.

But there were plumes aplenty at Chanel — a favourite of its founder Gabrielle Chanel — as it celebrated her fascination with birds and flight.

The giant birdcage was also a nod to Chanel's iconic bird on a swing advert from 1992 starring French singer Vanessa Paradis and her black tail feathers.

Elvis Presley's granddaughter Riley Keough sat on the swing to sing this time.

With the main entrance of the Grand Palais now bearing Gabrielle Chanel's name as a part of a 30 million-euro ($33 million) deal to stage its shows at the Paris landmark, the brand wanted to plant a flag during uncertain times.

 

No rush 

for new designer 

 

Without a creative director since June after Virginie Viard — who took over from Lagerfeld after his death in 2019 — bowed out, Chanel's studio designed the spring summer collection, riffing on some of the label's standards, from its trademark tweeds to lacy flapper dresses and flying jackets.

But it was the feathers that stood out, used in ruff-like collars on crocheted bombers and on 1920s-style gowns inspired by the glamour of French writer Colette's forays into music hall and cabaret.

Chanel chief Bruno Pavlovsky told AFP that the French company would not be rushed into finding a replacement for Viard, who was Lagerfeld's righthand woman for decades.

"You should not have a knife at our throat" if you are going to make "the right choices", he insisted, saying there would likely be an announcement by the end of the year.

Tom Ford, John Galliano, Simon Porte Jacquemus and French fashion editor Carine Roitfeld top the list of names mentioned to take over, though Pavlovsky would not be drawn on rumours.

With the big luxury Paris houses seeing profits fall as Chinese buyers button their purses, he said it was "the time for us to bounce back. Virginie did a great job over the last five years — indeed these last 30 years when she was at Karl's side”.

"The strength of the brand is that it can take its time because we have teams who are super solid," Pavlovsky told AFP before the show.

 

Virtuoso Vuitton 

 

Hollywood stars Hilary Swank and Willem Dafoe later walked for the Italian label Miu Miu, Prada's avant garde little sister.

Veteran designer Miuccia Prada — who has a doctorate in political science — called her show "Truthless Times" and had her models walk through a recreation of a newspaper printers' press hall, with copies of her show notes flying overhead.

On a day of spectacular shows, arguably the most impressive came at the end at the Louvre, where Louis Vuitton's Nicolas Ghesquiere produced a virtuoso panorama of colour and style, with barely two looks that were alike.

The couturier sent his models down a super long runway seemingly made up of Louis Vuitton suitcases and travel trunks.

His shoes and sandals also caught the eye of a star-studded front row that included movie stars Zendaya, Cate Blanchett and Alicia Vikander and South Korean singer Lisa of Blackpink.

They began with flat men's style sandals with overhanging straps and ended in dreamy puffball "cloud" slippers that might also be handy for bringing up the shine on the marble floors of Hollywood mansions.

Mission to probe smashed asteroid launches despite hurricane

By - Oct 07,2024 - Last updated at Oct 07,2024

MIAMI — Europe's Hera probe successfully launched Monday on a mission to inspect the damage done by a NASA spacecraft that smashed into an asteroid during the first test of Earth's planetary defences.
 
Despite fears that an approaching hurricane could delay the launch, the probe blasted off on a SpaceX rocket into cloudy skies from Cape Canaveral in the US state of Florida just before 11:00 am local time (1500 GMT).
 
Hera's mission is to investigate the aftermath of NASA's Double Asteroid Redirection Test (DART), which deliberately crashed into the Dimorphos asteroid in 2022 roughly 11 million kilometres from Earth.
 
The fridge-sized DART spacecraft successfully knocked the asteroid well off course, demonstrating that humanity may no longer be powerless against potentially planet-killing asteroids that could head our way.
 
The European Space Agency (ESA) said that Hera will conduct what it has dubbed a "crime scene investigation".
 
"Hera will gather the data we need to turn kinetic impact into a well-understood and repeatable technique on which all of us may rely one day," ESA chief Josef Aschbacher said on the agency's broadcast of the launch.
 
The tense liftoff on SpaceX's Falcon 9 rocket was met with applause from teams on the ground.
 
"We had a lot of tears -- and outside in the public event, people were jumping around and spilling their beers," ESA broadcast host Matthew Russell said.
 
Around an hour after liftoff, Hera then separated from the rocket in space, beginning its two-year journey towards Dimorphos.
 
There was more applause minutes later when the team on the ground received the first signal from the spacecraft, indicating a successful launch.
 
 Hurricane, rocket anomaly 
 
The launch had been put into doubt by the intensifying Hurricane Milton, with SpaceX warning on Sunday that there was only a 15 percent chance of a launch.
 
Milton is the latest hurricane to hit the Gulf of Mexico after Hurricane Helene, which has killed at least 230 people since striking Florida late last month. 
 
Hurricane Milton has been classified as "an extremely dangerous category 4 hurricane" and is expected to slam into the state by mid-week.
 
NASA said it will delay the launch of its Europa Clipper mission, which had been scheduled from Cape Canaveral on Thursday, due to "anticipated hurricane conditions" as Milton moves east across Florida over the week.
 
Hera's launch had also faced a potential delay due to an anomaly involving a Falcon 9 rocket during the launch of SpaceX's Crew-9 astronaut mission late last month.
 
But on Sunday, the US Federal Aviation Administration gave the last-minute green light, saying the nature of the problem posed little risk for Hera.
 
Next year, Hera is planned to get a gravitational boost as it flies past Mars, arriving near Dimorphos in December 2026 to begin its six-month investigation.
 
Dimorphos, which is actually a moonlet orbiting its big brother Didymos, never posed a threat to Earth.
 
After DART's impact, Dimorphos shed material to the point where its orbit around Didymos was shortened by 33 minutes -- proof that it was successfully deflected. 
 
Analysis of the DART mission has suggested that rather than being a single hard rock, Dimorphos was more a loose pile of rubble held together by gravity.
 
"The consequence of this is that, instead of making a crater" on Dimorphos, DART may have "completely deformed" the asteroid, said Hera's principal investigator Patrick Michel.
 
Nothing heading our way 
 
The 363-million-euro ($400 million) mission will be equipped with two nanosatellites. 
 
One will land on Dimorphos and probe inside the asteroid with radar, a first on such an asteroid. The other will study its composition from farther out.
 
An asteroid wider than a kilometre -- which could trigger a global catastrophe on a scale that wiped out the dinosaurs -- is estimated to strike Earth every 500,000 years or so.
 
An asteroid around 140 metres wide -- which is a little smaller than Dimorphos but could still take out a major city -- hits our home planet around every 20,000 years.
 
Most of these celestial objects come from the asteroid belt between Mars and Jupiter. Almost all those bigger than a kilometre wide are known to scientists, and none are expected to threaten Earth in the next century.
 
There are also no known 140-metre asteroids on a collision course with Earth -- but only 40 percent of those space rocks are believed to have been identified.
 

US duo win Nobel for gene regulation breakthrough

By - Oct 07,2024 - Last updated at Oct 07,2024

Nobel Prize winner in Physiology or Medicine, Victor Ambros

STOCKHOLM — US scientists Victor Ambros and Gary Ruvkun won the Nobel Prize in Medicine on Monday for their discovery of microRNA and its role in how genes are regulated, solving a decades-old mystery, the Nobel Assembly at Sweden's Karolinska Institute said.
 
If gene regulation goes awry, it can lead to serious diseases such as cancer, diabetes, or autoimmune illnesses.
 
"Their groundbreaking discovery revealed a completely new principle of gene regulation that turned out to be essential for multicellular organisms, including humans," the jury said.
 
Ruvkun said he was shocked to win the prestigious prize.
 
"It's quite a sea change," the 72-year-old professor at Harvard Medical School told AFP after receiving the news in a call from the prize committee in the early hours of Monday.
 
"I've won other awards in the past, but those were very quiet in comparison." 
 
"There's already been TV crews and photographers, and 300 email messages from friends!" he said, as his dog barked at the front door with more reporters arriving.
 
Ruvkun shared that he and Ambros are "buddies" and had a congratulatory video call that morning.
 
"We just FaceTimed to high-five. We've been friends for years."
 
Ruvkun told Swedish public radio SR he looked forward to the Nobel gala banquet on December 10 in Stockholm, where the laureates will receive their prizes from the hands of Sweden's King Carl XVI Gustaf.
 
"It's a party. You don't think of a bunch of scientists as party animals but we really are," he said.
 
Ruvkun told AFP the pair would be "celebrating like crazy," praising Ambros as "always positive and wonderful."
 
The Nobel committee failed to reach Ambros by telephone to give him the news. He heard it instead from an SR reporter who called.
 
"Wow, that's incredible! I didn't know that," the 70-year-old professor at the University of Massachusetts medical school said, adding: "Good. Wonderful."
 
Collaborating but working separately, Ruvkun and Ambros conducted research on a one millimetre roundworm, C. elegans, to determine why cell mutations occurred and when.
 
They discovered microRNA, a new class of tiny RNA molecules that play a crucial role in gene regulation, which in turn allows each cell to select only relevant instructions.
 
Their findings were published in two articles in 1993. 
 
"The seminal discovery of microRNA has introduced a new and unexpected mechanism of gene regulation," Thomas Perlmann, secretary general of the Nobel Assembly, told reporters.
 
"MicroRNAs are important for our understanding of embryological development, normal cell physiology and diseases such as cancer," he said.
 
Medical trials under way 
 
Gunilla Karlsson Hedestam, a biology professor at the Karolinska Institute, told reporters that "though there are no very clear applications available yet in microRNAs, understanding them, knowing that they exist, understanding their counter regulatory networks, is always the first step."
 
"There are quite a lot of trials ongoing, not only against cancer but also other diseases, cardiovascular, kidney diseases," she said. 
 
The Nobel Prize consists of a diploma, a gold medal and a $1 million cheque to be shared by the pair.
 
Last year, the medicine prize went to Katalin Kariko and Drew Weissman for work on messenger RNA (mRNA) technology that paved the way for Covid-19 vaccines.
 
The Nobel season continues this week with the announcement of the winners of the physics prize on Tuesday and the chemistry prize on Wednesday.
 
They will be followed by the much-anticipated prizes for literature on Thursday and peace on Friday.
 
The economics prize winds things up on Monday, October 14.
 
For Tuesday's physics prize, Swedish public radio SR's science experts suggested the honour could go to Swiss physicist Christoph Gerber, a pioneer in the development of the atomic force microscope.
 
"This is a microscope that gives 3D images on such an incredibly small scale that they sometimes are even atomic resolution," said SR science reporter Camilla Widebeck.
 
The tool has become indispensable in nanotechnology and nano research, she added.
 
The Clarivate analytics group also highlighted David Deutsch and Peter Shor for their work on quantum algorithms and quantum computing.
