| A 'fairly simple' breakthrough makes accessing stored hydrogen more efficient Posted: 10 Feb 2022 08:40 AM PST A new catalyst extracts hydrogen from hydrogen storage materials easily and efficiently. The process occurs at mild temperatures and under normal atmospheric conditions, without using metals or additives. |
| Brainy birds may fare better under climate change Posted: 10 Feb 2022 05:49 AM PST Many North American migratory birds are shrinking in size as temperatures have warmed over the past 40 years. But those with very big brains, relative to their body size, did not shrink as much as smaller-brained birds, according to new research. The study is the first to identify a direct link between cognition and animal response to human-made climate change. |
| Your microbiome shapes your life. But where did it come from? Posted: 09 Feb 2022 12:50 PM PST The gut microbiome is an ecosystem of hundreds to thousands of microbial species living within the human body. These populations affect our health, fertility, and even our longevity. But how do they get there in the first place? New research reveals crucial details about how the bacterial communities that comprise each of our individual gut microbiomes are acquired. These findings have major implications for treatments such as fecal transplants and probiotic administration. |
| In animal battles, cheaters can win Posted: 08 Feb 2022 04:17 PM PST Animal weapons can be a lot like plastic swords: impressive, but ultimately cheap. Some animals pretend to be bigger than they are by building weapons out of metabolically cheap inert materials, such as chitin and keratin. The prop weapons are also cheaper to maintain. |
