Biotech fit for the Red Planet: New method for growing cyanobacteria under Mars-like conditions

NASA, in collaboration with other leading space agencies, aims to send its first human missions to Mars in the early 2030s, while companies like SpaceX may do so even earlier. Astronauts on Mars will need oxygen, water, food, and other consumables. These will need to be sourced from Mars, because importing them from Earth would be impractical in the long term. In Frontiers in Microbiology, scientists show for the first time that Anabaena cyanobacteria can be grown with only local gases, water, and other nutrients and at low pressure. This makes it much easier to develop sustainable biological life support systems.

Study questions whether pubs can effectively prevent COVID-19 transmission risk

A new first-of-its-kind study has questioned whether pub operators can effectively and consistently prevent COVID-19 transmission—after researchers observed risks arising in licensed premises last summer.

Large-scale study finds genetic testing technology falsely detects very rare variants

A technology that is widely used by commercial genetic testing companies is "extremely unreliable" in detecting very rare variants, meaning results suggesting individuals carry rare disease-causing genetic variants are usually wrong, according to new research published in the BMJ.

Drinking, smoking, and drug use linked to premature heart disease in the young

Recreational drinking, smoking, and drug use is linked to premature heart disease in young people, particularly younger women, finds research published online in the journal Heart.

Ageism and sexism barring grandmothers from initiatives to save newborn lives in Global South

Ageism, sexism, and Western ideals of the nuclear family have excluded grandmothers from national and international policy initiatives to save newborn lives in the Global South, suggests an analysis published in the online journal BMJ Global Health.

Could long-distance interactions between individual molecules forge a new way to compute?

New physics rules tested on quantum computer

Aalto researchers have used an IBM quantum computer to explore an overlooked area of physics, and have challenged 100-year-old notions about information at the quantum level.

Membrane building blocks play decisive role in controlling cell growth

Lipids are the building blocks of the cell membrane. In addition to their structural function, some lipids also play a regulatory role and decisively influence cell growth. This has been investigated in a new study by scientists at Martin Luther University Halle-Wittenberg (MLU). The impact of the lipids depends on how they are distributed over the plasma membrane. The study was published in The Plant Cell.

Neanderthals and Homo sapiens used identical Nubian technology

Long held in a private collection, the newly analyzed tooth of an approximately nine-year-old Neanderthal child marks the hominin's southernmost known range. Analysis of the associated archaeological assemblage suggests Neanderthals used Nubian Levallois technology, previously thought to be restricted to Homo sapiens.

Bacterial degradation of the MYC oncogene: A new cancer treatment strategy?

Scientists at Lund University have discovered how E. coli bacteria target and degrade the well-known oncogene MYC, which is involved in many forms of cancer. The study is now published in Nature Biotechnology.

Commuters are inhaling unacceptably high levels of carcinogens

A new study finds that California's commuters are likely inhaling chemicals at levels that increase the risk for cancer and birth defects.

Invasive flies prefer untouched territory when laying eggs

A recent study finds that the invasive spotted wing drosophila (Drosophila suzukii) prefers to lay its eggs in places that no other spotted wing flies have visited. The finding raises questions about how the flies can tell whether a piece of fruit is virgin territory—and what that might mean for pest control.

Managing crab and lobster catches could offer long-term benefits

The UK's commercial fishing industry is currently experiencing a number of serious challenges.

It forever changed history when it crashed into Earth about 66 million years ago.

A machine-learning approach to finding treatment options for COVID-19

When the COVID-19 pandemic struck in early 2020, doctors and researchers rushed to find effective treatments. There was little time to spare. "Making new drugs takes forever," says Caroline Uhler, a computational biologist in MIT's Department of Electrical Engineering and Computer Science and the Institute for Data, Systems and Society, and an associate member of the Broad Institute of MIT and Harvard. "Really, the only expedient option is to repurpose existing drugs."
