A team of researchers from the U.K., China, and Italy has found evidence that suggests oxygen depletion in the world's oceans led to the end-Triassic mass extinction. In their paper published in the journal Science Advances, the group describes their study of ancient rocks found in multiple locations around the world.

One way to harness solar energy is by using solar electricity to split water molecules into oxygen and hydrogen. The hydrogen produced by the process is stored as fuel, in a form that can be transferred from one place to another and used to generate power upon demand. To split water molecules into their component parts, a catalyst is necessary, but the catalytic materials currently used in the process, also known as the oxygen evolution reaction, are not efficient enough to make the process practical.

"Everyone knows these statements aren't literally true, but although we might understand their figurative meaning, they continue to reflect, and influence, how we think. Even biologists, being quite human, too often think metaphorically and assign properties to genes that genes don't have. The metaphor works because our society has a deeply embedded belief in genes as clearly identifiable material things which explain our individual natures, making them inherent from the moment of our conception and thus predictable. If hydrogen and oxygen are the causal atoms of water, genes are the causal atoms of our existence."

Younger generations are blamed for the pandemic's spread, but also face the brunt of the transmission risk that comes with keeping the economy going. 6 MINUTE READ BY REBECCA RENNER PUBLISHED SEPTEMBER 17, 2020 WHEN PARAMEDICS RUSHED the pregnant Honduran woman into the emergency room, 28-year-old Chuan-Jay Jeffrey Chen stood ready to receive her. It was April, and the pandemic had already taken over his final year as an emergency medicine resident. Of all the coronavirus patients surging into Massachusetts General Hospital in Boston, this 32-year-old patient remains Chen's most memorable. The woman was so short of breath she could barely speak, so Chen would need to intubate her-a tricky procedure that requires precision as well as speed. Every moment without oxygen causes a patient's chances of survival to decline; pregnancy further complicates the scenario by making airways swollen, causing blood pressure to drop more quickly. As Chen set to work and talked her through the steps in Spanish, he also tried to calm his own nerves. "I knew I had very little margin for error," says Chen. The woman's husband had been barred from entering the building because of coronavirus restrictionsgen-z
