Risk for a severe form of retinopathy of prematurity, which can cause blindness in extremely premature babies, was halved when the newborns were given a new supplement combining various fatty acids. This was shown in a Swedish study led from the University of Gothenburg. The study, now published in JAMA Pediatrics, is described as groundbreaking in its field. It documents a clear fall in retinopathy of prematurity (ROP) among extremely premature (EP) infants (born before 28 weeks' gestation), whose retinal blood vessels are not fully developed. The condition can cause ...

When the body's immune response to an infection gets out of control, the result can be sepsis, a life-threatening condition in which an overwhelming inflammatory response can lead rapidly to failure of multiple organs and death. In a new study, researchers at UC Santa Cruz have identified a long noncoding RNA (lncRNA) molecule that regulates the expression of pro-inflammatory genes in immune system cells called macrophages and affects the susceptibility of mice to septic shock. This lncRNA, called GAPLINC, was previously studied for its role in cancer, but it turns out to be the most highly expressed lncRNA in macrophages, which play a central role in inflammation. ...

A previously unknown root trait allows some cereal plants to grow deeper roots capable of punching through dry, hard, compacted soils, according to Penn State researchers, who suggest that harnessing the inherited characteristic could lead to crops better able to deal with a changing climate. "This discovery bodes well for American and global agriculture because the trait helps corn, wheat and barley grow deeper roots, which is important for drought tolerance, nitrogen efficiency and carbon sequestration," said Jonathan Lynch, distinguished professor in plant science. "Breeding for this trait should be helpful in developing new crops for climate mitigation." Called multiseriate cortical sclerenchyma by the researchers -- or MCS -- the phenotype is ...

New research from North Carolina State University reveals that probiotic Lactobacillus bacteria use enzymes situationally to manipulate bile acids and promote their own survival in the gut. These findings further elucidate the complicated relationship between bile acids and gut bacteria and could eventually enable researchers to design lactobacilli with therapeutic properties, thereby engineering a healthier human gut environment. Bile acids are key players in digestion and overall gut health. Produced in the liver and released after we eat, these acids not ...

Just as plants and animals on land are keenly attuned to the hours of sunlight in the day, life in the oceans follows the rhythms of the day, the seasons and even the moon. A University of Washington study finds the biological light switches that make this possible. Single-celled organisms in the open ocean use a diverse array of genetic tools to detect light, even in tiny amounts, and respond, according to a study published Feb. 1 in the Proceedings of the National Academy of Sciences. "If you look in the ocean environment, all these different organisms have this day-night cycle. They are very in tune with each other, even as they get moved around. How do they know when it's day? How do they know when it's night?" said lead ...

There are fossils, found in ancient marine sediments and made up of no more than a few magnetic nanoparticles, that can tell us a whole lot about the climate of the past, especially episodes of abrupt global warming. Now, researchers including doctoral student Courtney Wagner and associate professor Peter Lippert from the University of Utah, have found a way to glean the valuable information in those fossils without having to crush the scarce samples into a fine powder. Their results are published in Proceedings of the National Academy of Sciences. "It's so fun to be a part of a discovery like this, something that can be used ...

Most snakes get from A to B by bending their bodies into S-shapes and slithering forward headfirst. A few species, however -- found in the deserts of North America, Africa and the Middle East -- have an odder way of getting around. Known as "sidewinders," these snakes lead with their mid-sections instead of their heads, slinking sideways across loose sand. Scientists took a microscopic look at the skin of sidewinders to see if it plays a role in their unique method of movement. They discovered that sidewinders' bellies are studded with tiny pits and have few, if any, of the tiny spikes found on the bellies of other snakes. The Proceedings ...

CAMBRIDGE -- The temperature of a planet is linked with the diversity of life that it can support. MIT geologists have now reconstructed a timeline of the Earth's temperature during the early Paleozoic era, between 510 and 440 million years ago -- a pivotal period when animals became abundant in a previously microbe-dominated world. In a study appearing today in the Proceedings of the National Academy of Sciences, the researchers chart dips and peaks in the global temperature during the early Paleozoic. They report that these temperature variations coincide with the planet's ...

In a new study led by Yale Cancer Center, researchers have discovered a novel metabolic gatekeeper mechanism for leukemia. This mechanism depends on a molecule called PON2, which could lead to a new treatment for the disease. The findings were published online today in the Proceedings of the National Academy of Sciences (PNAS). B cells are effector cells of the adaptive immune system and are marked by low energy levels, which prevent transformation to leukemia. In this study, Yale scientists identified high expression levels of the detoxifying lactonase ...

Philadelphia, February 1, 2021 - Researchers at Children's Hospital of Philadelphia (CHOP) have demonstrated that autism spectrum disorder (ASD) may be caused by defects in the mitochondria of brain cells. The findings were published online by the Proceedings of the National Academy of Sciences. Multiple studies have revealed hundreds of mutations associated with autism spectrum disorder, but there is no consensus as to how these genetic changes cause the condition. Biochemical and physiological analyses have suggested that deficiencies in mitochondria, the "batteries" of the cell that produce ...

Scientists have identified a group of drugs that may help stop a leading cause of vision loss after making an unexpected discovery that overturns a fundamental belief about DNA. The drugs, known as Nucleoside Reverse Transcriptase Inhibitors, or NRTIs, are commonly used to treat HIV. The new discovery suggests that they may be useful against dry macular degeneration as well, even though a virus does not cause that sight-stealing condition. A review of four different health insurance databases suggests that people taking these drugs have significantly reduced risk of developing dry macular degeneration, a condition that affects ...

A 15-year experiment on Arctic shrubs in Greenland lends new understanding to an enduring ecological puzzle: How do species with similar needs and life histories occur together at large scales while excluding each other at small scales? The answer to this question has important implications for how climate change might shift species' distributions across the globe. The study was published today in the journal PNAS and led by the University of California, Davis. Its findings also reveal trends related to carbon sequestration and carbon exchange as the Arctic becomes both greener and browner. EXPANSION AND EXCLUSION Like lines of traffic traveling the same roads at the same time without crashing into each ...

CLEVELAND - Evidence suggests particulate matter is the air pollutant which poses the greatest threat to global health. Studies have shown that exposure to particulate matter smaller than 2.5 microns is associated with acute and chronic elevations in blood pressure (BP) as well as hypertension. In the study "The Benefits of Intensive Versus Standard Blood Pressure Treatment According to Fine Particulate Matter Air Pollution Exposure" published this week in the journal Hypertension, researchers at University Hospitals (UH) and Case Western Reserve University (CWRU) ...

A paper by a multidisciplinary team of scientists affiliated with various Brazilian institutions, including the University of São Paulo (USP) and the National Cancer Institute (INCA), shows that people of African descent are less likely to find a donor in the National Register of Voluntary Bone Marrow Donors (REDOME) than people with predominantly European ancestry. The paper is published in Frontiers in Immunology. REDOME is the world’s third-largest bone marrow bank, with more than 5 million registered voluntary donors. According to the study, having mainly African genetic ancestry can reduce a person’s chances of finding a donor by up to 60%, and having African copies of HLA genes, which must be compatible with ...

Obesity and its duration are significant risk factors for type 2 diabetes, cardiovascular events, multiple cancers and decreased quality of life. According to the Centers for Disease Control and Prevention, obesity affects 20.6% of adolescents ages 12-19 in the United States, meaning a potential lifetime of dealing with this condition. Complications from obesity can also result in a potentially decreased life expectancy of five to 20 years for these youth. In a new study published in Pediatrics, researchers at Children's Hospital Colorado (Children's Colorado) have found that both younger and older adolescents have similar weight loss, resolution of high blood pressure and high cholesterol, nutritional impacts and improvement in quality of life after bariatric surgery. These results ...

Decoy protein intercepts spike of coronavirus Virus prevented from infecting human cells Protein may be new way to treat and prevent COVID-19 CHICAGO --- Northwestern Medicine scientists have developed a new protein that acts as a trickster to neutralize the COVID-19 infection in a human kidney organoid, a miniature organ made from stem cells in the lab. The protein is a variant of ACE2 (angiotensin converting enzyme-2), the receptor the coronavirus uses to enter and infect human cells. The modified protein intercepts the S spike of the coronavirus and fools it into binding to it rather than the real ACE2 receptor in cell membranes. ...

NEW YORK, NY (Feb. 1, 2021)--Errors in the way chromosomes are packed into antibody-producing B cells appear to play a role in the development of B cell-related blood cancers, according to a new study by researchers at Columbia University Vagelos College of Physicians and Surgeons. The findings could lead to new biomarkers for predicting the onset of these cancers and to a new class of cancer therapies that prevent or correct harmful changes in genome architecture. The study was published online Feb. 1 in the journal Nature Genetics. Antibodies are made by immune cells called ...

Taking a particular type of medication to treat enlarged prostate is associated with a reduced risk of developing Parkinson's disease, according to a large observational study led by researchers at the University of Iowa, with colleagues in Denmark and China. The findings, published Feb. 1 in JAMA Neurology, provide compelling evidence that terazosin, and similar medications, might have the potential to prevent or delay the development of Parkinson's disease. The new study used data on almost 300,000 older men from two large, independent patient datasets--the Truven ...

A new kind of wearable health device would deliver real-time medical data to those with eye or mouth diseases, according to Huanyu 'Larry' Cheng, Dorothy Quiggle Career Development Professor in the Penn State Department of Engineering Science and Mechanics (ESM). Cheng recently published a paper in Microsystems & Nanoengineering on new micro- and nano-device technology that could revolutionize how certain health conditions are monitored and treated. "We sought to create a device that collects both small and large substances of biofluids such as tears and saliva, which can be analyzed for certain conditions on a rapid, continuous basis, rather than waiting on test results from samples in a lab," he said. The sensors would be placed near the tear duct or mouth to collect samples, ...

Winter survival of honey bee colonies is strongly influenced by summer temperatures and precipitation in the prior year, according to Penn State researchers, who said their findings suggest that honey bees have a "goldilocks" preferred range of summer conditions outside of which their probability of surviving the winter falls. The results of this study, which used several years of survey data provided by the Pennsylvania State Beekeeper's Association and its members, enabled the development of a tool for forecasting honey bee winter survival to support beekeepers' management decisions, the researchers said. Honey bees contribute more than $20 billion in pollination services to agriculture in the United States and generate another ...

Toxin-antitoxin (TA) systems are now known to negatively control plasmid replication, according to Thomas Wood, Biotechnology Endowed Chair and professor of chemical engineering in the Penn State College of Engineering. Plasmids, or extra-chromosomal bits of DNA, allow bacteria to evade antibiotics, making the antibiotics ineffective in halting a bacterial infection. The presence or absence of plasmids impacts a bacterium's resistance to antibiotics and its ability to cause infection -- important points related to fighting bacterial infections, according to Wood. "Each year, there are at least 700,000 deaths worldwide because of bacterial infections, a growing number that is projected to increase to 10 million by 2050," Wood said. "And of course, the effectiveness ...

February 1, 2021 - Extracorporeal cardiopulmonary resuscitation (ECPR) is a potentially lifesaving treatment for patients in cardiac arrest when the circulation can't be restored by conventional CPR. New guidelines for ECPR in adults and children, developed by the Extracorporeal Life Support Organization (ELSO), are presented by the ASAIO Journal, official journal of the American Society for Artificial Internal Organs. The journal is published in the Lippincott portfolio by Wolters Kluwer. A specialized application of extracorporeal membrane oxygenation (ECMO), ECPR is increasingly being used to provide a chance ...

Imagine a rubber band that was capable of snapping itself many times over, or a small robot that could jump up a set of stairs propelled by nothing more than its own energy. Researchers at the University of Massachusetts Amherst have discovered how to make materials that snap and reset themselves, only relying upon energy flow from their environment. The discovery may prove useful for various industries that want to source movement sustainably, from toys to robotics, and is expected to further inform our understanding of how the natural world fuels some types of movement. Al Crosby, a professor of polymer science and engineering in the College of Natural Sciences at UMass Amherst, ...
