Study suggests mask-wearing reduces the odds of self-infection with SARS-CoV-2
COVID-19 typically turns deadly when the virus infects the lungs. Hence, how exactly SARS-CoV-2 gets deep into the respiratory tract has been a pressing question since the pandemic started early last year. One pathway is well known: Most people catch … Continue reading

Degradable plastic polymer breaks down in sunlight and air
Plastic trash chokes shorelines and oceans, in part because plastic polymers do not easily decompose. But a new kind of environmentally degradable plastic could help change that: It breaks down in about a week in sunlight and air, according to … Continue reading

Emotional associations, more than knowledge, determine how much people care about the deep sea
With new technological advances in deep-sea mining, the ocean floor’s trove of valuable metals and rare earth elements is coming within reach of commercial mining operations. The impending reality of this practice, and its associated environmental risks, raises the question … Continue reading
New culturing techniques track crucial stage of embryo development
The second week of gestation is crucial for human development, as the growing embryo needs to implant in the mother’s womb to survive. Many early pregnancies fail at this point, but it has been difficult to determine exactly why. Lacking … Continue reading

Harmful social behaviors are the toughest to shift
Social norms changed dramatically during the pandemic. Six-foot distancing and mask wearing became de facto rules in some communities, while elsewhere, wearing a mask was seen as an invitation for harassment. A new study in Proceedings of the Royal Society … Continue reading
Easily made, robust chemical reagents could be game changer for developing world science
Enzymes and other chemical reagents are crucial for all sorts of life sciences research. Typically, they’re produced in industrial processes by modified bacteria; then they’re extracted and purified. But scientists in many parts of the world struggle to access such … Continue reading

A popular household fern may be the first known eusocial plant
Staghorn ferns are popular houseplants, sporting long, antler-like fronds that poke out from a brown, tissue-papery base. They may also be the first known example of a plant that exhibits a type of social organization—that is, the first plant thought … Continue reading

Newly observed forces help geckos stick to surfaces
Even the most advanced glues can’t match the remarkable toe of the gecko: Its impressive stickiness can be quickly deactivated and can support much more than the animal’s weight as it runs across surfaces smooth or rough, wet or dry, … Continue reading

Atlas identifies genome regions that regulate plant cell identity
Zoom in on the leaf of a corn plant, and you’ll find a patchwork of about 20 different cell types. A recent study, published in Cell, provides an atlas of critical genomic regions that control cell identity in six different … Continue reading
