Begging gene leads to drone food

A team of biologists discovered a genetic factor that determines the begging behaviour of drones in bees, allowing them to obtain essential proteins from worker bees. The 'fruitless' or 'Fru' protein regulates this complex social behaviour and influences a neural network of around 1,800 neurons.

Artificial metabolism turns waste CO2 into useful chemicals

Researchers at Northwestern University and Stanford University develop a new artificial metabolism that converts waste carbon dioxide into acetyl-CoA, a universal metabolite used by all living cells. The system, called Reductive Formate Pathway (ReForm), uses engineered enzymes to perform metabolic reactions never seen in nature.

How climate policies that incentivize and penalize can drive the clean energy transition

A new study from the University of California San Diego and Princeton University shows how a mix of subsidies for clean energy and taxes on pollution can significantly reduce greenhouse gas emissions. When incentives are applied consistently, the economy can reach an 80% reduction in energy-related carbon emissions by mid-century.

Stardust study resets how life’s atoms spread through space

A team of astronomers has discovered that the winds of giant stars like R Doradus are driven by complex processes, rather than being powered solely by starlight and stardust. The study used advanced computer simulations to model how starlight interacts with dust grains, finding that they are too small to be pushed outward by starlight ...
