Microplastics, with a size from 1 micron to < 5 millimeters, are pervasive pollutants that have been found in all parts of the global ocean, and have made their way into the marine food webs. Researchers, led by University of British Columbia UBC’s Institute for the Oceans and Fisheries scientists and Ecuadorian researchers from Galápagos and the ESPOL Polytechnic School (Guayaquil, Ecuador), looked closely at how microplastic bioaccumulation was affecting the endangered Galápagos penguin (Spheniscus mendiculus) as an indicator species to trace how deeply microplastic bioaccumulation has entered the food web in the isolated Galápagos Islands. An ...

Obesity is a problem in the United States. In fact, 42.5% of U.S. adults aged 20 and over have the disease. Not only is obesity the nation’s second leading cause of preventable death (behind only smoking cigarettes), it also leads to other serious health issues, including an increased risk of type 2 diabetes, high blood pressure, heart disease, stroke, cancer, sleep apnea and liver disease. The disease and its side effects impose a significant financial burden on America’s health care system. As many make — and often fail to keep — New Year’s resolutions about exercise and weight loss goals, University ...

LA JOLLA (January 22, 2024)—Salk Professor Ronald Evans has been named the 2024 recipient of the Japan Prize in the field of Medical Science and Pharmaceutical Science. The Japan Prize Foundation awards this prestigious international award annually to “express Japan’s gratitude to international society.” "I am delighted to extend my congratulations to Ron for this well-deserved recognition in honor of his discovery of nuclear hormone receptors,” says Salk President Gerald Joyce. “This accomplishment not only reflects the exceptional caliber of Ron’s research ...

UNSW medical researcher Dr David Jacques and his team have discovered how the human immunodeficiency virus (HIV) breaches the cell nucleus to establish infection, a finding that has implications beyond HIV biology. To infect cells, HIV must enter the target cell and make its way to the nucleus in the cell’s centre where enough copies of its genetic code can be produced to infect other cells. To safely complete this quest, the virus builds a protective protein coat – a capsid – to shield itself from the host’s immune defences geared to destroy it. Until ...

On a cliffside at Mesa Verde National Park in southern Colorado, a fuzzy bee was industriously gnawing at the red sandstone. Making a loud grinding sound, the insect used its powerful jaws to drill tunnels and holes in rocks, where it would build a nest for raising offspring.  The bee, known as Anthophora pueblo, is a type of digger bee native to Colorado. Discovered less than a decade ago, the bee has quickly become Adrian Carper’s favorite pollinator.  “This is just one example of how crazily diverse our native bees are,” said Carper, an ...

Mayo Clinic researchers studying the genetics of people who had recently developed dilated cardiomyopathy, one of the most common causes of heart failure, have found a particular gene to target for developing future drug therapy treatments. The disease makes it harder for the heart's left ventricle to pump blood effectively to the rest of the body. In this first genome-wide association study, the researchers sought to understand why some patients get better after developing the condition — and some don't. "We found genetic variation in the CDCP1 gene, a gene that no one has heard of in ...

MSU has a satellite uplink/LTN TV studio and Comrex line for radio interviews upon request. Images EAST LANSING, Mich. – Thousands of types of bacteria live in the human gut. They help digest the food we eat and absorb nutrients, but these bacteria don’t just do this to be kind to humans, there is a benefit for them too. Elizabeth Heath-Heckman, an assistant professor in the College of Natural Science, has received a five-year National Institutes of Health grant from the National Institute for General Medical Sciences totaling $1.9 million to support her research studying ...

When SARS-CoV-2 enters the human body, the virus’ spike protein binds to a cell, allowing the virus to infiltrate and begin replicating. A new study from Tulane University, conducted in partnership with Florida International University and published in Protein Science, has identified a protein that may be the glue that helps COVID’s spike protein stick. The study found that a small piece of a proteoglycan called perlecan LG3 – a protein most commonly found in blood vessels and the brain – ...

EMBARGOED FOR RELEASE UNTIL 4 P.M. ET, WEDNESDAY, JANUARY 24, 2024 MINNEAPOLIS – Migraine is often underdiagnosed and untreated, and even when it is treated, it can be difficult to treat early enough as well as find strategies to prevent attacks. A new study looks at ways to more accurately predict when a migraine will occur—through the use of mobile apps to track sleep, energy, emotions and stress—to enhance the ability to prevent attacks. The study is published in the January 24, 2024, online issue of Neurology®, the medical journal of ...

While surgeons have more commonly used the exoscope in various intracranial procedures, its use in spinal surgery has been underreported.  Researchers and neurosurgeons at the Medical University of South Carolina (MUSC) retrospectively compared the operative microscope to the 3D exoscope in a recent study published in World Neurosurgery and found better outcomes among both surgeons and patients when using the exoscope.  Stephen Kalhorn, M.D., FAANS, was the principal investigator on the study, and he says the traditional operative microscope has ...

UNIVERSITY PARK, Pa. — An estimated 1,600 people in the U.S. contract a serious infection from Listeria bacteria in food each year and, of those individuals, about 260 people die, according to the Centers for Disease Control and Prevention. Penn State researchers may now better understand how the bacteria, called Listeria monocytogenes, survive and persist in fruit-packing plants by evading and surviving sanitizers.   According to their study, which is now available online and will be published in the June issue of the journal Biofilm, biofilms — comprising otherwise harmless microorganisms that attach to each ...

Humpback whale singing dominates the marine soundscape during winter months off Maui. However, despite decades of research, many questions regarding humpback whale behavior and song remain unanswered. New research revealed a daily pattern wherein whales move their singing away from shore throughout the day and return to the nearshore in the evening. The findings were led by the University of Hawaiʻi, in partnership with NOAA’s Hawaiian Islands Humpback Whale National Marine Sanctuary, and published in Royal Society Open Science.  “Singers may be attempting to reduce the chances of their song being drowned ...

Obesity among primary school children in the UK spiked during the COVID-19 lockdown, with a 45% increase between 2019/20 and 2020/21 among 4-5-year-olds, according to a study published on January 24, 2024 in the open-access journal PLOS ONE by Iván Ochoa-Moreno from the University of Southampton, UK, and colleagues. The authors estimated that without reversals, increased obesity rates in Year 6 children alone will cost society an additional £800 million in healthcare. During the first year of the pandemic, school closures dramatically altered the routines of young children. Cancellation of organized sports, ...

A new study suggests that heatwaves are exacerbating socioeconomic inequalities in Brazil, with people who are female, elderly, Black, Brown, or who have lower educational levels potentially facing greater risk of death during heatwaves. Djacinto Monteiro dos Santos of Universidade Federal do Rio de Janeiro, Brazil, and colleagues present these findings in the open-access journal PLOS ONE on January 24, 2024. As climate change progresses, heatwaves are becoming hotter, longer, and more frequent in many regions ...

At least 8% of the human genome is genetic material from viruses. It was considered ‘junk DNA’ until recently, but its role in human development is now known to be essential Researchers at the Spanish National Cancer Research Centre (CNIO) describe for the first time the role of these viruses in a key process in development, when cells become pluripotent few hours after fertilization The finding, published in Science Advances, is relevant for regenerative medicine and for the creation of artificial ...
