U.S. urges DNA synthesis firms to ramp up screening for biosecurity threats

Worried that bioterrorists will take advantage of the growing ease of creating risky pathogens in the lab, federal officials are beefing up guidelines for companies that sell nucleic acids such as DNA and RNA. The recommendations, released earlier this month, update the U.S. Department of Health and Human Services’s (HHS’s) 13-year-old guidance for screening orders to cover more forms...

First detailed U.S. scientific integrity draft policies get mixed responses

Keep working on it. That’s the reaction of U.S. science watchdog groups to the first attempts by federal health agencies to flesh out a promise by President Joe Biden to restore trust in government by ensuring that government scientists are free to do their jobs without political meddling. One week after taking office in January 2021, Biden ordered a review of...

Mice thrive at 6700 meters up—higher than any mammals were thought able to live

Few places are as inhospitable as the top of Llullaillaco, a 6700-meter volcano on the border between Chile and Argentina. Winds howl nonstop and no plants live there; daytime temperatures never get above freezing and plummet even more come nightfall. Oxygen levels are just 40% of those at sea level, too low for mammals to live there —or so biologists thought until 3 years ago when a...

Women leaders at six top research universities urge more diversity in semiconductor workforce

A push to rejuvenate the U.S. semiconductor industry won’t succeed without including more women and minorities in the workforce. That’s the rationale for a new academic consortium aimed at increasing diversity in microelectronics being launched by the women presidents and engineering deans at six prominent universities. “This is personal for us,” say the founders of the...

Israel-Hamas war sends shock waves through scientific community

Shock waves from the war between Israel and Hamas are rocking the scientific community in the region and around the world. In Israel, universities are mourning scientists and others killed in the 7 October surprise attack by Hamas militants. Hamas, widely considered a terrorist organization, rules the Gaza Strip. Academic laboratories are emptying as foreign graduate students...

Billions boost next-generation COVID-19 vaccine and treatments

Six months after announcing the $5 billion Project NextGen to develop treatments and vaccines that can “stay ahead of COVID-19,” the U.S. government has awarded 20 contracts that reveal what much of that sum will support. The Department of Health and Human Services (HHS) announced on 13 October that up to $1.2 billion will go to three vaccine developers aiming to...

Parasitic worms may control minds of insects with ‘borrowed’ genes

Adult horsehair worms look about how you’d expect given their name: They’re long, noodlelike creatures that resemble wiggling horse hairs. They live and reproduce in water, but their young only develop inside the bodies of other animals—usually terrestrial insects such as praying mantises. Once they’ve finished growing inside their unwitting vessel, the worms must convince their...

Senate hearing goes smoothly for Biden’s pick for NIH director

A Senate hearing today to consider the nomination of Monica Bertagnolli to lead the National Institutes of Health (NIH) went well for the cancer surgeon. Committee Chair Bernie Sanders (I–VT) grilled Bertagnolli about NIH’s role in controlling drug prices, and Republican members pressed her on politically sensitive research. But the overall tone was friendly and suggested no major...

A giant European telescope rises as U.S. rivals await rescue

A web of steel girders is rising from the flattened summit of Cerro Armazones, 3000 meters above sea level in Chile’s Atacama Desert. The dome it will support will be vast—with a footprint as big as a soccer field and almost as tall as the Statue of Liberty— and unexpectedly nimble: It will smoothly rotate on rails as a giant telescope inside tracks stars through the night....

Archaeology society spars over publishing photos of Indigenous burial offerings

As editor-elect of the journal Southeastern Archaeology , Rob Beck helped choose a cover photo for the penultimate issue of 2020. It showed about 20 ceramic vessels, some painted with colorful patterns. They had been excavated in the early 1900s from the Crystal River Archaeological State Park in Florida, home to some of the region’s oldest ancient Indigenous earthworks....

New initiative aims to sequence half a million genomes of people with African ancestry for health studies

An industry-academic initiative announced today aims to create the largest ever database of genomes exclusively from people with African ancestry. Four biopharma companies contributing $80 million have teamed up with Meharry Medical College to launch the effort, which hopes to recruit up to 500,000 African Americans and people from Africa and combine their DNA and medical data into a...

U.K. government vow to end ‘woke’ science draws rebuke from researchers

A pledge by the United Kingdom’s Conservative government to “kick woke ideology out of science” has stirred controversy among many scientists. In recent remarks, the top U.K. science official said the government aims to stop “the steady creep of political correctness” in research and will review the use of questions related to sex and gender in scientific studies. Many...

Serpents that bit ancient Egyptians slither into focus

If a snakebitten patient stumbled into an Egyptian physician’s office some 2500 years ago, the doctor might have reached for a papyrus scroll describing 34 snakes and their bites in hieratic script used by ancient Egyptians, with advice on how to treat them. This ancient manual is considered one of the world’s first medical texts. Since the scroll was first translated 60...

Low serotonin levels might explain some Long Covid symptoms, study proposes

Although theories abound, there is still no clear explanation for how infection with SARS-CoV-2 leads to lingering difficulty concentrating, problems with attention and memory, and other, often-debilitating symptoms associated with Long Covid. Now, researchers studying people who reported these and other symptoms months postinfection propose a new possibility: That...
