Scientists repot flowering plants ’ tree of life—and find it has tangled roots
About 150 million years ago, life on Earth began a complete revamp, thanks to the rapid rise of one giant group: the flowering plants, or angiosperms. The more efficient photosynthesis of magnolias, waterlilies, as well as many early lineages now extinct pumped oxygen into the atmosphere, and their nectar and fruits provided new types of food for insects and other animals, fueling new, more complex ecosystems that still dominate the planet today.
The sprouting of angiosperms happened so fast that the origins of certain groups has long been mired in mystery. Now, almost 300 plant biologists have banded together to r...

Swoop system tested in Alzheimer ’s patients
Portable MRI developer Hyperfine has enrolled the first patients in a trial to test its Swoop system in Alzheimer’s disease patients undergoing amyloid-targeting therapy.
The CARE PMR (Capturing ARIA Risk Equitably with Portable MR) observational study is designed to assess the clinical utility and workflow benefits of Swoop system. Imaging will be performed at infusion centers and clinics to help physicians detect amyloid-related imaging abnormalities (ARIAs) in Alzheimer’s patients.
The study is led by Tammie Benzinger, MD, PhD, a professor of radiology and chief of MRI service at the Mallinckrodt Institute of Radi...

Universities should experiment to improve caregiver support, U.S. National Academies says
“Innovation in caregiving support is desperately needed.” That’s one of the key take-home messages of a report released today by the National Academies of Sciences, Engineering, and Medicine (NASEM)
exploring how the U.S. academic community can better support caregivers
—a group that
particularly struggled to stay afloat during the pandemic
. Many of the report’s recommendations are familiar, including paid family and medical leave and flexible grant deadlines. But the report also highlights the need for creative solutions, encouraging institutions to experiment with new approaches and to coll...

Why China Might Beat the U.S. Back to the Moon
Roughly 6,800 miles separate humanity’s past and future on the surface of the moon. It’s the approximate distance between the Sea of Tranquility—where Apollo 11’s Neil Armstrong and Buzz Aldrin first landed on July 20, 1969—and Shackleton Crater at the south lunar pole. The vicinity of Shackleton is where astronauts from the U.S. and, quite likely, taikonauts from China (from the Chinese word “taikong,” meaning space or cosmos) will touch down sometime during or before 2030, taking advantage of local ice deposits that can be harvested for water, breathable oxygen, and even rocket f...

Where did India ’s people come from? Massive genetic study reveals surprises
South Asia is home to one of the most diverse assemblages of people in the world. A mélange of different ethnic identities, languages, religions, castes, and customs makes up the 1.5 billion humans who live here. Now, scientists have revealed the most detailed look yet of how this population took shape.
In the largest ever modern whole-genome analysis from South Asia—published as a preprint last month on bioRxiv, researchers reveal new details about
the origin of India’s Iranian ancestry and when ancient hunter-gatherers settled the region
. The study also turns up a surprise: an unexpectedly rich dive...

Women in healthcare experience higher burnout rates than male peers
Women in healthcare occupations -- from physicians to nurses, clinical social workers, and mental health providers -- experience more stress and burnout compared to their male peers, researchers have found.
There are ways to mitigate this phenomenon, however, including boosting job satisfaction and maintaining a work-life balance, noted study corresponding author Judith Frame, PhD, of the George Washington University School of Medicine and Health Sciences in Washington, DC. Frame and colleagues' results were published February 22 in Global Advances in Integrative Medicine and Health.

Surgeons urged to screen for osteoporosis in THA patients
Screening for osteoporosis using dedicated bone scans among total hip arthroplasty (THA) patients remains alarmingly low, according to research presented February 14 at the American Academy of Orthopedic Surgeons (AAOS) annual meeting in San Francisco.
Researchers at George Washington University in Washington, DC, identified 380,226 patients in a U.S. claims database who underwent THA. They found that out of 53% of patients who were considered high-risk for osteoporosis, just 12.4% received preoperative dual-energy x-ray absorptiometry (DEXA) scans.
“Our study showed a high prevalence of THA patients at risk for osteop...

Low-dose PEM shows promise in breast cancer detection
Low-dose positron emission mammography (PEM) can detect invasive breast cancer in a feasible manner, according to research published February 9 in Radiology: Imaging Cancer.
A team led by Vivianne Freitas, MD, from the University of Toronto found that PEM performed comparably to MRI in breast cancer detection and could serve as a supplemental imaging method for evaluating dense breasts.
"This groundbreaking imaging technique presents a compelling alternative, mirroring the clinical utility of traditional mammography and MRI but utilizing considerably lower doses of radiation when compared with previously molecular breast...
