PULLMAN, Wash.–Washington State University researchers have concluded that feeding a growing global population with sustainability goals in mind is possible. Their review of hundreds of published studies provides evidence that organic farming can produce sufficient yields, be profitable for farmers, protect and improve the environment and be safer for farm workers. The review study, “Organic Agriculture in the 21st Century,” …
Gut microbes are well known to contribute to health and disease, but what has been less clear is how the host controls gut microbes. A study published January 13 in Cell Host & Microbe now reveals that mice and humans produce small molecules (microRNAs) from their GI tract, which are shed in feces, to regulate the composition of gut microbes …
The Paris Climate Change Conference failed Humanity and has locked in a catastrophic temperature rise of about plus 2.7 degrees C. All ordinary folk can do is to boycott the worst polluters. World Bank analysts have revised annual greenhouse gas (GHG) pollutions upwards by 50% to 64 billion tonnes CO2-e by properly accounting for land use for animal husbandry and …
Once considered the cause of most disease, “germs” are now increasingly being recognized as essential to our survival and well-being by extending our genetic capabilities with “supra human” powers. A groundbreaking study published in the journal Nature titled, “Transfer of carbohydrate-active enzymes from marine bacteria to Japanese gut microbiota,” adds to a growing body of microbiome research challenging the prevailinggenome-centric …
Tens of millions of trees in California are now at risk because of sustained drought, according to new research. And a different study in a different journal foresees a parched future for the evergreen forests not just in the Golden State but in the entire US southwest. Gregory Asner of the Carnegie Institution for Science in Stanford, California and colleagues …
A new study of wild bees identifies 139 counties in key agricultural regions of California, the Pacific Northwest, the upper Midwest and Great Plains, west Texas, and the southern Mississippi River valley that have the most worrisome mismatch between falling wild bee supply and rising crop pollination demand. The study and map were published in the Proceedings of the National Academy …
A momentous new report took up just six pages in a recent issue of the Proceedings of the National Academy of Sciences. The title had no spoilers: “Rising morbidity and mortality in midlife among white non-Hispanic Americans in the 21st century.” The authors were Anne Case of the Woodrow Wilson School of Public and International Affairs, and Angus Deaton of …
his week, Angus Deaton will receive the Nobel Memorial Prize in Economics “for his analysis of consumption, poverty, and welfare.” Deservedly so. Indeed, soon after the award was announced in October, Deaton published some startling work with Anne Case in the Proceedings of the National Academy of Sciences – research that is at least as newsworthy as the Nobel ceremony. …
Giants once roamed the earth. Oceans teemed with ninety-foot-long whales. Huge land animals–like truck-sized sloths and ten-ton mammoths–ate vast quantities of food, and, yes, deposited vast quantities of poop. A new study shows that these whales and outsized land mammals–as well as seabirds and migrating fish–played a vital role in keeping the planet fertile by transporting nutrients from ocean depths …
UCLA geochemists have found evidence that life likely existed on Earth at least 4.1 billion years ago — 300 million years earlier than previous research suggested. The discovery indicates that life may have begun shortly after the planet formed 4.54 billion years ago. The research is published today in the online early edition of the journal Proceedings of the National …
