A new study maps for the first time the evolutionary history of the world's terrestrial vertebrates: amphibians, birds, mammals and reptiles. It explores how areas with large concentrations of evolutionarily distinct species are being impacted by our ever-increasing "human footprint."
Toronto and Spanish physicians describe in CMAJ (Canadian Medical Association Journal) an approach to create dedicated COVID-19 patient units, infection control protocols and care teams to help other hospitals safely care for patients.
The Chapman University National COVID-19 and Mental Health Survey provides an in-depth look at the experiences of 4,149 adults living in the United States. The study asked questions about how the COVID-19 pandemic is impacting people's mental health, physical health, romantic relationships and encounters of prejudice and discrimination.
About 9,000 years ago in the Balsas River Valley of southwestern Mexico, hunter-gatherers began domesticating teosinte, a wild grass. Fast-forward to the present, and what was a humble perennial has been turned into the world's biggest grain crop: maize.
Humanity deeply relies on maize, or corn, but just when it became a major food crop in the Americas has been a source of mystery and dispute.
The Latin name for brook trout -- Salvelinus fontinalis -- means "speckled fish of the fountains," but a new study by Penn State researchers suggests, for the first time, that the larger streams and rivers those fountains, or headwaters, flow into may be just as important to the brook trout.

New results from the NASA/ESA Hubble Space Telescope suggest the formation of the first stars and galaxies in the early Universe took place sooner than previously thought. A European team of astronomers have found no evidence of the first generation of stars, known as Population III stars, as far back as when the Universe was just 500 million years old.
BUFFALO, N.Y. - Lockdowns implemented across the world due to the COVID-19 pandemic have negatively impacted diet, sleep and physical activity among children with obesity, according to University at Buffalo research.
The study, published in April in Obesity, examined 41 overweight children under confinement throughout March and April in Verona, Italy.
A new, hair-sprouting dollop of human skin created in the lab might one day help prevent hair loss.
Organoids are small, lab-grown cell groupings are designed to model real-world organs -in this case, skin. A paper published in Nature describes the hairy creation as the first hair-baring human skin organoid made with pluripotent stem cells, or the master cells present during early stages of embryonic development that later turn into specific cell types.
The coronavirus has prompted many medical centers to switch from in-person appointments to video visits. A new study from UCSF Benioff Children's Hospitals suggests that for some hospitals, video visits may become a permanent feature of the patient-provider landscape.
People with severe vision loss can less accurately judge the distance of nearby sounds, potentially putting them more at risk of injury, according to new research published in the journal Scientific Reports.
Researchers from Anglia Ruskin University's Vision and Eye Research Institute (VERI) tested participants with different levels of vision loss, presenting them with speech, music and noise stimuli, and different levels of reverberation (echoes).
Participants were asked to judge the distance of the different sounds, as well as the size of the room.
Almost any grocery store is filled with products made from corn, also known as maize, in every aisle: fresh corn, canned corn, corn cereal, taco shells, tortilla chips, popcorn, corn sweeteners in hundreds of products, corn fillers in pet food, in soaps and cosmetics, and the list goes on.
The "unparalleled" discovery of remarkably well-preserved ancient skeletons in Central American rock shelters has shed new light on when maize became a key part of people's diet on the continent.
Until now little was known about when humans started eating the crop, now a staple of meals around the globe that shapes agricultural landscapes and ecosystem biodiversity.
EAST HANOVER, NJ - June 3, 2020 - Kessler Foundation released the results of the first national survey of college graduates with disabilities coming of age under the Americans with Disabilities Act, signed into law 30 years ago on July 26, 1990. The 2020 Kessler Foundation National Employment and Disability Survey: Recent College Graduates is the third in a groundbreaking series of surveys aimed at gaining detailed information on the ways people with disabilities achieve inclusion in the workplace.
A USC School of Pharmacy-led team has engineered a new, faster way to make drugs that precisely target malignant cells - while leaving healthy tissue undamaged - that could lead the way to better treatments for numerous types of cancer.
