NASA explains the mission to bring samples of Mars soil, rock and atmosphere back to Earth
Since September, the Perseverance rover has been picking along an ancient river delta on Mars, its robotic arms reaching out with whirling steel drill bits to core rocks, scoop soil and suck small amounts of the red planet's atmosphere into titanium tubes.
Scaling the cost of government programs using a cost-per-person price tag improves comprehension by the general public
NASA's Mars Sample Return Mission aims to bring 30 samples of rock, soil and atmosphere now being collected by the Perseverance rover back to Earth sometime in the early 2030s. The goal is to look for signs of past life and also to find out more about the Red Planet before humans visit it.
Spain, Portugal dryness 'unprecedented' in 1,200 years
Government policies often are presented with hefty price tags, but people often zone out as more zeros are added to the total cost. A new study from Carnegie Mellon University suggests that rescaling the cost of programs can increase a person's understanding of funding choices, which may improve how people participate in the policy debate. The results are available in the July issue of the journal...
Cern gears up for more discoveries 10 years after ‘God particle’ find
Parts of Portugal and Spain are the driest they have been in a thousand years due to an atmospheric high-pressure system driven by climate change, according to research published Monday, warning of severe implications for wine and olive production.
Study explores coevolution of mammals and their lice
With the Higgs boson already in the bag, the Large Hadron Collider begins another period of data collectionIt’s 10 years to the day since evidence of the Higgs boson – the elusive particle associated with an invisible mass-giving field – was announced. But for Prof Daniela Bortoletto the memories are as fresh as ever.“I just remember joy. I remember that everybody was so happy. And what...
Largest genetic atlas for zebrafish 'breakthrough' for biomedical research
According to a new study, the first louse to take up residence on a mammalian host likely started out as a parasite of birds. That host-jumping event tens of millions of years ago began the long association between mammals and lice, setting the stage for their coevolution and offering more opportunities for the lice to spread to other mammals.
The Higgs boson, ten years after its discovery
Medical and life science researchers will benefit from the most comprehensive atlas yet of genetic data on zebrafish, newly published research suggests.
Time-lapse of the world's largest waterlily species discovered at London's Kew Gardens – video
Ten years ago, on July 4 2012, the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) announced the discovery of a new particle with features consistent with those of the Higgs boson predicted by the Standard Model of particle physics. The discovery was a landmark in the history of science and captured the world's attention. One year later it won François Englert and Peter Higgs the...
What are whale sharks up to?
A giant waterlily grown at Kew Gardens has been named as a new species in the first discovery of its type in more than a century. Scientists at Kew suspected for decades there could be a third species of giant waterlilyNewly identified waterlily species is world’s largest Continue...

Researchers use AI to detect new family of genes in gut bacteria
In just a few hours, scientists can tell which variant has infected a COVID-19 patient -- a critical task that can potentially influence treatment decisions but takes days or weeks at most medical centers.

Male dogs four times more likely to develop contagious cancer on nose or mouth than females
Using artificial intelligence, researchers have discovered a new family of sensing genes in enteric bacteria that are linked by structure and probably function, but not genetic sequence. The findings offer a new way of identifying the role of genes in unrelated species and could lead to new ways to fight intestinal bacterial infections.

NASA satellite breaks from orbit around Earth, heads to moon
Schiff base-metal complexes exhibit promising antibacterial and antioxidant properties. However, conventional methods for their preparation can be time-consuming. To reduce the reaction time and improve the quality and quantity of the products, researchers designed a new synthesis technique that uses microwave irradiation and methanol for the preparation of amino acid Schiff base copper complexes...
The Download: China’s livestreaming crackdown, and a huge police data hack
A satellite the size of a microwave oven successfully broke free from its orbit around Earth on Monday and is headed toward the moon, the latest step in NASA's plan to land astronauts on the lunar surface again.
The big idea: should we worry about sentient AI?

China wants to control how its famous livestreamers act, speak, and even dress For Zeng, a young Chinese woman, an hour scrolling Douyin, the domestic version of TikTok, has become a daily ritual.…
Will adaptability save the North Atlantic right whale?
A Google employee raised the alarm about a chatbot he believes is conscious. A philosopher asks if he was right to do soThere’s a children’s toy, called the See ’n Say, which haunts the memories of many people born since 1965. It’s a bulky plastic disc with a central arrow that rotates around pictures of barnyard creatures, like a clock, if time were measured in roosters and pigs....
New screening technique could accelerate and improve mRNA therapies
Scientists and whale rescue experts are trying to figure out how to save the North Atlantic right whale population from decreasing further in light of climate change and changes in...
ATLAS and CMS release results of most comprehensive studies yet of Higgs boson's properties
Therapeutics based on messenger RNA, or mRNA, can potentially treat a wide range of maladies, including cancer, genetic diseases, and as the world has learned in recent years, deadly viruses.
Ode to the Spring review – Chinese exploration of pandemic ground zero in Wuhan
Today, exactly ten years after announcing the discovery of the Higgs boson, the international ATLAS and CMS collaborations at the Large Hadron Collider (LHC) report the results of their most comprehensive studies yet of the properties of this unique particle. The independent studies, described in two papers published today in Nature, show that the particle's properties are remarkably consistent...
Russian cosmonauts display flag of occupied Luhansk region on ISS
Telling five Covid-related stories, this platitudinous urban-interconnection drama offers lectures on virtue and self-sacrifice and feels like state propagandaThis interminable anthology film about the pandemic feels like being force-fed lectures on altruism, family responsibility, self-sacrifice and neighbourly forbearance by the Chinese government (which produced it).
