To understand how professional networks contribute to persistent gender disparities in corporate leadership, researchers analyzed data from more than 19,000 corporate employees over 20 years. Publishing March 12 in the Cell Press journal Patterns, their results show that educational, employment, and social networks matter for both men and women, but women rely on more complex social networks to reach director-level positions than men. Women with professional ...

Mass General Brigham study results signal a call to do further research into the connection between vitamin D supplementation and long COVID In a large, randomized trial, researchers at Mass General Brigham have found that high-dose vitamin D3 did not reduce COVID-19 infection severity, but may impact long COVID outcomes. Results of the study are published in The Journal of Nutrition. “There’s been tremendous interest in whether vitamin D supplements can be of benefit in COVID, and this is one of the largest and most rigorous randomized trials on the subject,” said senior author JoAnn Manson, MD, DrPH, ...

A new study led by UCLA researchers suggests that a personalized counseling program can significantly help women who have survived cervical precancer or cervical cancer to quit smoking — and does so at a cost that researchers say represents good value for healthcare systems. The findings, published in JAMA Network Open, show that the specialized program, called Motivation and Problem-Solving (MAPS), which combines standard nicotine replacement therapy with up to six individualized counseling sessions over a year, helped twice as many women quit smoking compared to women who had standard smoking cessation support. “Smoking is a major risk factor for cancer recurrence and ...

About The Study: In this cohort study, adverse childhood experience (ACE) exposure was associated with an increased risk of treatment-resistant depression even after accounting for unmeasured familial confounding. The findings highlight the importance of preventing ACEs and incorporating ACE history into clinical assessment to identify individuals with major depressive disorder who may be at elevated risk for treatment resistance.  Corresponding Author: To contact the corresponding author, Ying Xiong, PhD, MMedSc, email ying.xiong@ki.se.

A new, national analysis published in the Aesthetic Surgery Journal suggests the future growth of aesthetic surgery may lie far from traditional luxury markets. UC Davis Health researchers found that Southern, Midwestern and rural regions of the United States are growing as high-demand areas, despite limited access to board-certified plastic surgeons. The study, conducted by researchers at UC Davis Medical Center, analyzed Google search behavior alongside workforce data across 210 U.S. Designated Market Areas. Researchers found that consumer demand is rising nationwide but remains unevenly matched with surgeon distribution. This imbalance has revealed multiple “plastic surgery deserts” ...

A University of Virginia School of Medicine researcher has received $3.4 million from the National Institutes of Health to increase the availability of weight-management programs that offer beneficial personalized feedback.   Rebecca Krukowski, PhD, and her colleagues are aiming to support people who track or “self-monitor” their diet, exercise and weight in weight-management programs. The researchers will create a semi-automated feedback system to find the “sweet spot” of combining human expertise and support with automated feedback to help participants stay on ...

(WASHINGTON — Mar. 12, 2026) — Hematology-oncology trained physicians who treat sickle cell disease reported higher rates of burnout (60%) than their counterparts who do not provide sickle cell care (43%) despite no differences in grit and resilience between the two groups. The data were published in the American Society of Hematology’s journal, Blood Advances.    “This is the first and only data on burnout, grit, ...

The Amazon rainforest is famous for storing massive amounts of carbon in its trees and soils, helping regulate the global climate. Yet a paper published today in New Phytologist shows that one of South America’s largest carbon-storing ecosystems exists in an often-overlooked grassy savanna: the Cerrado in Brazil.  The study was led by Larissa Verona, a technician working with senior scientist Amy Zanne at Cary Institute of Ecosystem Studies and a former graduate student at Universidade Estadual de Campinas in Brazil, where she carried out the work. The study is the first in-depth assessment of carbon stocks in the Cerrado’s groundwater-fed wetlands, known ...

Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) belong to a spectrum of neurodegenerative diseases with overlapping symptoms, characterized by muscle wasting, paralysis, dementia, and other serious impairments. There are currently no effective treatments. Many patients have a common hallmark: A protein called TDP-43 clumps together in the neurons of the brain to form tiny lumps. Researchers at DZNE and Ulm University Hospital, together with international experts, have now discovered ...

WASHINGTON—A mouse study found that a father’s nicotine exposure can affect the offspring’s ability to process sugar and may contribute to diabetes risk, according to new research published in the Journal of the Endocrine Society. An estimated 40.1 million people in the United States have diabetes, according to the U.S. Centers for Disease Control and Prevention. Having diabetes puts people at risk of developing other conditions like heart disease, kidney disease and nerve damage. Since diabetes affects more than 12 percent of Americans and is a chronic disease, the costs of treatment are high. Tobacco ...

PLYMOUTH MEETING, PA [March 12, 2026] — New research in the March 2026 issue of JNCCN—Journal of the National Comprehensive Cancer Network suggests that exercise may help people with cancer stay mentally sharp and better able to handle daily tasks, work, and social activities through chemotherapy treatment delivered on an every two-week cycle. This first-of-its-kind, nationwide, multicenter, phase III trial randomized patients to receive an exercise prescription, Exercise for Cancer Patients (EXCAP©®), which included individually-tailored walking and simple resistance band exercises, along with their usual chemotherapy treatment. By ...

Across the animal kingdom, sound is more than communication – it’s a signal of survival and success. From birds and primates to insects, fish and amphibians, animals broadcast acoustic “advertisements” to defend territory, attract mates and reveal their physical condition. Because these calls can reflect traits such as body size, strength or health, they play a powerful role in sexual selection and help shape how species compete and reproduce. Parasites can influence these mating signals. Infections ...

Traditional medicine (TM), defined by the WHO as the knowledge and practices based on indigenous theories, is used by over 80% of the global population, particularly in Asia, Africa, and Latin America. Modern medicine (MM), grounded in the biomedical model, excels in acute care but often lacks holistic perspectives. Importantly, many modern drugs—such as artemisinin and aspirin—originate from traditional knowledge. Integrating TM and MM aims to combine the strengths of both systems to deliver holistic, ...

Background and objectives Amoebiasis, or amoebic dysentery, is a gastrointestinal disorder caused by the parasite Entamoeba histolytica. The disease is endemic in parts of Africa, Asia, North and South America, leading to several deaths annually. Reported adverse effects associated with the current first-line treatment for amoebiasis, coupled with the evolution of resistance to it, call for the need to search for plant-based alternatives. This study systematically reviews medicinal plants with activity against Entamoeba histolytica. Methods The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) ...

In areas where freshwater is scarce, farmers often turn to treated wastewater to irrigate crops. And many regulators and consumers worry about exposing food to compounds routinely found in wastewater, including many psychoactive medications that treat mental disorders.   But new research from Johns Hopkins University has found that certain crops—tomatoes, carrots, and lettuce—store those chemicals in their leaves. This may be good news for tomato and carrot lovers who eat the fruit and roots of those vegetables, respectively.  The research, published today in Environmental Science ...

OSA is a common sleep disorder characterized by oxygen desaturation due to repeated airway collapse during sleep. This leads to oxygen desaturation or awakening from sleep. It is often linked to metabolic problems, cardiovascular disease, and a lower quality of life. OSA and insomnia symptoms often co-occur, a condition known as comorbid insomnia and sleep apnea or COMISA. This can complicate usual treatments like continuous positive airway pressure (CPAP) therapy, which is often recommended for moderate to ...

Fukuoka, Japan—Making a living brain transparent and watching its neurons fire without disturbing their function—sounds like science fiction, doesn't it? Yet the solution may already exist within our own bodies. In a paper published in Nature Methods on March 12, a research team led by Kyushu University introduces a new reagent called SeeDB-Live. It uses albumin—a common protein in blood serum—to clear tissue while preserving cellular function. The technique allows scientists to see deeper, brighter structures in both brain slices in a dish and living mice, reaching neural activity that was previously out of sight. “This ...

A Kobe University study shows that small aquatic beetles survive catfish attacks by resisting ingestion inside the catfish’s mouth and being spat out alive. This research contributes to a deeper understanding of size-dependent predator-prey relationships in aquatic insects and fish. Once prey is captured by a predator, it’s easy for us to think of it as a death sentence. But in certain predator-prey relationships, the fight is far from over. For example, Kobe University ecologist SUGIURA Shinji revealed in a previous study that a small aquatic beetle, Regimbartia attenuata, can survive frog predation by escaping alive through the frog’s vent. He explains, “Whether ...

Scientists at the University of Cambridge have developed a new way to alter complex drug molecules using light rather than toxic chemicals – a discovery that could accelerate and improve how medicines are designed and made.  Published today (Thursday 12 March) in Nature Synthesis, the study introduces what the team calls an “anti-Friedel–Crafts” reaction. A classic Friedel–Crafts reaction uses strong chemicals or metal catalysts under harsh experimental conditions. This means the reaction can only happen in the early stages of drug manufacturing, and is followed by many additional chemical steps to produce ...

A pioneering research-industry partnership has used advances in indoor farming technology to grow pea shoots fortified with Vitamin B12, opening an exciting route to market for farmers and addressing a major public health need. The partnership between the John Innes Centre and the Quadram Institute, based at the Norwich Research Park, the University of Bristol, and indoor farm specialists LettUs Grow, harnessed the latest aeroponic techniques to successfully deliver the recommended daily allowance (RDA) of Vitamin B12 within a 15-gram portion of pea shoots. The fortified salad crop not only exceeded expectations by delivering in excess of the RDA of Vitamin B12 in a single serving ...

Researchers have developed a capsule-based method that makes it possible to analyse the same cell through multiple experimental steps. The technology overcomes a long-standing limitation in cell research and could open new ways to study disease mechanisms at the single-cell level. In a study published in the scientific journal Science, Visiting Professor Linas Mazutis at Umeå University and his research team present a new technology for analysing individual cells. The method addresses a long-standing technical challenge in cell research: until now, scientists have usually ...

Tokyo, Japan – Researchers have uncovered evidence for our Sun joining a mass migration of similar “twins” leaving the core regions of our galaxy, 4 to 6 billion years ago. The team created and studied an unprecedentedly accurate catalogue of stars and their properties using data from the European Space Agency’s Gaia satellite. Their discovery sheds light on the evolution of our galaxy, particularly the development of the rotating bar-like structure at its center.   While archaeology on Earth studies the human past, galactic archaeology traces the vast journey of stars and galaxies. For example, scientists know that our Sun was born around ...
