Photosystem II is a protein complex in plants, algae and cyanobacteria that is responsible for splitting water and producing the oxygen we breathe. Over the past few years, an international collaboration between scientists at the Department of Energy's Lawrence Berkeley National Laboratory, SLAC National Accelerator Laboratory and several other institutions have been able to observe various steps...
Canada's spy agency today issued a warning about the national security risk posed by some foreign investment — but isn't saying which state-owned enterprises and foreign state actors it's particularly worried...
As the world increasingly turns to aqua farming to feed its growing population, there's no better time than now to design an aquaculture system that is sustainable and efficient.
Before there were animals, bacteria or even DNA on Earth, self-replicating molecules were slowly evolving their way from simple matter to life beneath a constant shower of energetic particles from space.
US accused by Russia of trying to circumvent 1967 treaty banning ownership of areas of the moonCountries joining Nasa’s exploration of the moon will be asked to sign up to a series of guiding principles known as the Artemis accords. Announced on 15 May, the accords are a set of broad themes that the agency hopes will form the basis of agreements to be negotiated with each country involved in the...

You may have noticed that we’re getting less snow in winter as the climate warms. But how much? A new study provides the best estimate yet of much snow North America has been losing, and shows Eurasia’s snowfall has held...
In the bone marrow, blood stem cells via precursor cells give rise to a variety of blood cell types with various functions: white blood cells, red blood cells, or blood platelets. In which cell type a cell develops depends on various factors. The correct dosage of the enzyme MOF at the right time triggers developmental programs in blood stem cells and precursor cells, and the cells differentiate...
A new study shows how an effective but largely abandoned treatment for Type 2 diabetes could be used again in combination with another drug to eliminate problematic side effects.
Buckling, the sudden loss of structural stability, is usually the stuff of engineering nightmares. But, as anyone who has ever played with a toy popper knows, buckling also releases a lot of energy. When the structure of a popper buckles, the energy released by the instability sends the toy flying through the air. Researchers have harnessed that energy and used buckling to their advantage to build...
From her laboratory in the far western reaches of Montana, Elizabeth Fischer is trying to help people see what they’re up against in COVID-19. Over the past three decades, Fischer, 58, and her team at the Rocky Mountain Laboratories, part of the National Institutes of Health’s (NIH) National Institute of Allergy and Infectious Diseases, have captured and created some of the more...
The news: North Dakota was one of the first American states to launch a coronavirus contact tracing app, in April. Now, several weeks into the process of reopening the state, the government in Bismarck says it will take advantage of the newly released Apple-Google exposure notification system—but that doing so will require it to run two separate apps. That even one of the...
Apple and Google have released long-awaited smartphone technology to notify people automatically if they might have been exposed to the coronavirus. The new technology is described as fixing problems in similar apps, such as not working across borders and draining users' phone...
NASA satellites have been providing forecasters with various types of imagery on Typhoon Amphan as it heads toward a landfall near the border of eastern India and Bangladesh on May 20.
From testing drugs to developing vaccines, the close study of the immune system is key to improving real-world health outcomes. T-cells are integral to this research, as these white blood cells help tailor the body's immune response to specific pathogens.

Conventional wisdom suggests that when a company generates more carbon emissions, investors should lower its stock price. After all, the company is generating a socially undesirable byproduct.
Rapidly rising water has overtaken dams and forced the evacuation of about 10,000 people from flooded communities in central Michigan, and the governor warned that one city could end up "under approximately 9 feet of water" Wednesday.
