NASA's new chief big on climate, hedges on 2024 moon landing
China's rogue rocket is in an uncontrolled free-fall towards Earth and no one knows where or exactly when it will burn through Earth's atmosphere, but the risk of debris hitting an inhabited area remains very small, experts told AFP Friday.
Massive molecular study uncovers clues to the evolution and diversification of essential plant family
NASA's new administrator is big on tackling climate and diversifying the agency's workforce, but hedging on whether the U.S. can put astronauts on the moon by 2024.
Archaeologists pinpoint population for the Greater Angkor region
The most comprehensive study of the family tree for legumes, the plant family that includes beans, soybeans, peanuts, and many other economically important crop plants, reveals a history of whole-genome duplications. The study also helps to uncover the evolution of genes involved in nitrogen fixation—a key trait likely important in the evolutionary spread and diversification of legumes and vital...
New research sets stage for development of salmonella vaccine
Long-running archaeological research, boosted by airborne lidar sensing and machine-learning algorithms, finds that Cambodia's Greater Angkor region was home to 700,000-900,000 people.
Growth of satire during 'age of politeness' saw worries ridicule could lead to abuse, research shows
With the COVID-19 vaccines on many people's minds, some may be surprised to learn that we do not yet have vaccines for many common infectious diseases.
Study describes new mechanism for terminating transcription of DNA into RNA in bacteria
The explosion of satire in the Georgian period saw philosophers worry mockery could lead to abuse, research shows.
Sleep disorders tally $94.9 billion in health care costs each year
A bacterial protein helps to stop transcription—the process of making RNA copies of DNA to carry out the functions of the cell—by causing the cellular machinery that transcribes the DNA to pause at the appropriate spots in the genome. The protein, known as NusG, pauses the transcription machinery at specific DNA sequences to facilitate what is called "intrinsic termination" and prevent...

new mechanism for terminating transcription of DNA into RNA in bacteria
Sleep disorders are associated with significantly higher rates of health care utilization including more doctors visits and prescriptions, placing an additional $94.9 billion in costs each year to the U.S. Health care system.

Listen to the Ingenuity helicopter humming through the Martian air
A bacterial protein helps to stop transcription -- the process of making RNA copies of DNA to carry out the functions of the cell -- by causing the cellular machinery that transcribes the DNA to pause at the appropriate spots in the genome.
WHO approves first Chinese Covid vaccine for emergency use
First came the amazing pictures, then the video. Now NASA is sharing sounds of its little helicopter humming above the surface of...
Why hotter clocks are more accurate
Sinopharm jab will also be added to Covax programme for the developing world in the coming weeksThe World Health Organization has given emergency use approval to one of the Chinese-made Sinopharm’s Covid-19 vaccines in a major boost to the product’s credibility.The long-awaited decision made on Friday by a WHO technical advisory group would also see the Chinese vaccine being included in the...

Deforestation of Brazilian Amazon hits record in April
A new experiment shows that the more energy consumed by a clock, the more accurate its timekeeping. This is the first time that a measurement has been made of the entropy -- or heat loss -- generated by a minimal clock tens of nanometers thick and 1.5 millimeters long. Understanding the thermodynamic cost involved in timekeeping is a central step along the way in the development of future...
Damage to white matter is linked to worse cognitive outcomes after brain injury
Deforestation of the Brazilian Amazon hit a record last month, the government reported Friday with figures that belie President Jair Bolsonaro's pledge to crack down on such destruction.

China's emissions now exceed all the developed world's combined
A new study challenges the idea that gray matter (the neurons that form the cerebral cortex) is more important than white matter (the myelin covered axons that physically connect neuronal regions) when it comes to cognitive health and function. The findings may help neurologists better predict the long-term effects of strokes and other forms of traumatic brain injury.
Soybean and linseed oils added to cows' diet improves the quality of milk
China now accounts for more greenhouse gas emissions than all of the world's developed nations combined, according to new research from Rhodium Group.
A Chinese rocket is falling back to Earth—but we don’t know where it will land
Inclusion of soybean and linseed oils in the diet of dairy cows made the fatty acid content of their milk even healthier for human nutrition. It also increased the proportions of omega-6 and omega-3, which in the right balance play a key role in preventing cardiovascular diseases, for example, as well as chronic inflammation and some kinds of cancer.
Winning gene combination takes all
Last week, China successfully launched Tianhe-1, the first part of its new space station, to be completed before the end of 2022. A week later, the mission is still making huge waves—and not in a good way. The core booster from the Long March 5B rocket that launched Tianhe-1 ended up in an uncontrolled orbit around Earth. It is expected to fall back to Earth this weekend, with current...
EXPLAINER: What are cicadas and why do they bug some people?
Researchers have traced the remaining last steps of the biological pathway that gives oats resistance to the deadly crop disease take-all.
Perseverance Mars rover captures video, audio of fourth Ingenuity flight
Cicadas, red-eyed bugs singing loud sci-fi sounding songs, can seem downright creepy. Especially since the trillions of them coming this year emerge from underground only every 17 years.
For the first time, a spacecraft on another planet has recorded the sounds of a separate spacecraft. NASA's Perseverance Mars rover used one of its two microphones to listen as the Ingenuity helicopter flew for the fourth time on April 30, 2021. A new video combines footage of the solar-powered helicopter taken by Perseverance's Mastcam-Z imager with audio from a microphone belonging to the...
