A team of scientists, led by the University of Bristol, with colleagues from the University of Florida, provide the first evidence for diet and subsistence practices of ancient East African pastoralists.
The development of pastoralism is known to have transformed human diets and societies in grasslands worldwide. Cattle-herding has been (and still is) the dominant way of life across the vast East African grasslands for thousands of years.
Countries looking to contain the spread of harmful species and diseases like COVID-19 should work together in multiple hotspots, according to a new model developed by an Arizona State University researcher.
Because it would be difficult to completely eliminate the novel coronavirus, mathematical modeling suggests countries should focus on keeping the rate of infection low by collaborating in multiple areas. In some circumstances, however, a clear division of labor may be called for.
How the embryo develops in the womb is a complicated process, that is still puzzling today. In particular, it is unresolved how the paternal genetic information that is also present in the embryo, and the emerging body cells based on their mixed "blueprint" are tolerated by the maternal immune system and not rejected upon recognition as foreign. While this process is now well understood in humans, pregnancies in the animal kingdom still provoke many unanswered questions.
ANN ARBOR--Offshore energy-producing platforms in U.S. waters of the Gulf of Mexico are emitting twice as much methane, a greenhouse gas, than previously thought, according to a new study from the University of Michigan.
Researchers conducted a first-of-its-kind pilot-study sampling air over offshore oil and gas platforms in the Gulf of Mexico. Their findings suggest the federal government's calculations are too low.
Researchers are ramping up production of a promising drug that has proven effective in obliterating SARS-CoV in cellular cultures. The team hopes that the drug might also be effective in the fight against SARS's close genetic cousin, the novel coronavirus (COVID-19).

Immunotherapies have revolutionized treatment for people with a variety of cancers. But when given to those with triple-negative breast cancer (TNBC), a particularly aggressive form of the disease, less than 20% respond.
"A big question in the field has been, Why are the rest not responding?" says Rumela Chakrabarti, an assistant professor at Penn's School of Veterinary Medicine.
A new chemical compound created by researchers at West Virginia University is lighting the way for renewable energy.
The compound is a photosensitizer, meaning it promotes chemical reactions in the presence of light. It has many potential applications for improving the efficiency of modern technologies ranging from electricity-producing solar panels to cell phones.

1. Diagnostic Tests in Response to the COVID-19 Pandemic: A Narrative Review
New Rochelle, NY, April 13, 2020--A new study has shown substantial variability in access to guideline-recommended hormone therapies for older transgender individuals insured through Medicare. The variability in Medicare coverage and out-of-pocket costs for feminizing and masculinizing therapies are detailed in an article published in LGBT Health, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
The latest CUNY coronavirus tracking survey found that a majority of (77%) of New Yorkers who typically attend holiday services found alternative ways to practice their faith during Easter and Passover week. Among the observant, 43% reported watching or listening to services on TV or radio, while 29% took part online. About one in five people (22%) who normally observe the holidays said they did not this year because of the virus.
SUMMARY
Researchers developed and demonstrated for the first time a silicon-based electro-optical modulator that is smaller, as fast as and more efficient than state-of-the-art technologies. By adding indium tin oxide (ITO) - a transparent conductive oxide found in touchscreen displays and solar cells - to a silicon photonic chip platform, the researchers were able to create a compact device 1 micrometer in size and able to yield gigahertz-fast, or 1 billion times per second, signal modulation.
DALLAS - April 13, 2020 - Cells in some of the body's most vulnerable entry routes to bacterial infection buffer themselves when the immune system detects danger by reorganizing the cholesterol on their surfaces, a new study led by UTSW scientists suggests. The findings, published today in Nature Microbiology, could offer new strategies for fighting infections that don't involve antibiotics.
Scientists at the Severinov Laboratory in Skoltech and their colleagues from Russia and the US have uncovered a new mechanism of bacterial self-defense against microcin C, a potent antibiotic weapon in the microscopic world that can sometimes turn on its master.
A new species of bent-toed gecko (Cyrtodactylus phnomchiensis) has been described from Cambodia's Prey Lang Wildlife Sanctuary by Wild Earth Allies Biologist Thy Neang in collaboration with North Carolina Museum of Natural Sciences' Herpetologist Bryan Stuart. This new species is described in ZooKeys.
