Early-life stress can disrupt maturation of brain’s reward circuits, promoting disorders

Irvine, Calif., Feb. 27, 2023 — A new brain connection discovered by University of California, Irvine researchers can explain how early-life stress and adversity trigger disrupted operation of the brain’s reward circuit, offering a new therapeutic target for treating mental illness. Impaired function of this circuit is thought to underlie several major disorders, such as depression, substance abuse and excessive risk-taking. In an article recently published online in Nature Communications, Dr. Tallie Z. Baram, senior author and UCI Donald Bren Professor and Distinguished Professor in the Departments of Anatomy & Neurobiology, ...

Rutgers researchers use artificial intelligence to predict cardiovascular disease

Researchers may be able to predict cardiovascular disease – such as arterial fibrillation and heart failure – in patients by using artificial intelligence (AI) to examine the genes in their DNA, according to a new Rutgers study. “With the successful execution of our model, we predicted the association of highly significant cardiovascular disease genes tied to demographic variables like race, gender and age.” said Zeeshan Ahmed, a core faculty member at the Rutgers Institute for Health, Health Care Policy and Aging ...

To promote exercise, planners must look beyond cities

ITHACA, N.Y. – To encourage more active lifestyles, public health agencies recommend mixed-use neighborhoods and “complete” streets that are friendlier to walkers and bikers, but new Cornell University research finds that while those strategies increase physical activity, an urban bias limits their applicability in many parts of the country. Planners in suburban and rural communities should focus more on promoting recreational programs, expanding transportation options and creating safer environments to help an aging population get more exercise, according to the researchers’ analysis of more than 1,300 U.S. counties and cities. “These ...

Shrinking age distribution of spawning salmon raises climate resilience concerns

By returning to spawn in the Sacramento River at different ages, Chinook salmon lessen the potential impact of a bad year and increase the stability of their population in the face of climate variability, according to a new study by scientists at UC Santa Cruz and NOAA Fisheries. Unfortunately, spawning Chinook salmon are increasingly younger and concentrated within fewer age groups, with the oldest age classes of spawners rarely seen in recent years. The new study, published February 27 in the Canadian Journal of Fisheries and Aquatic Sciences, suggests changes in hatchery practices and fishery management ...

Babies born preterm decreased and stillborn rates remained unchanged during the first four months of COVID-19 lockdowns, according to a largescale international study. The research of 52 million births from 26 countries, published in Nature Human Behavior, reported a 3-4 per cent reduction overall in preterm births, averting almost 50,000 preterm pregnancies during the first month of lockdown alone. But the decrease in preterm births was limited to only high-income countries including Australia. The International Perinatal Outcomes in the Pandemic (iPOP) Study, ...

Plugging immune cell leakage from tumors could improve skin cancer treatment

The number of specialized immune cells available for fighting skin cancer doubled when a new treatment blocked their escape from melanoma tumors, experiments in mice and human cells show. Researchers at NYU Langone Health and its Perlmutter Cancer Center who led the study found that combining a chemical blocker of immune cell exit with another drug type, an immunotherapy, stopped melanoma tumor enlargement in more than half of mice tested. Immunotherapy alone had previously failed to prevent the cancers’ growth. Recent advances in immunotherapies, medications designed to help the body’s immune defense system ...

Corralling ions improves viability of next generation solar cells

Researchers have discovered that channeling ions into defined pathways in perovskite materials improves the stability and operational performance of perovskite solar cells. The finding paves the way for a new generation of lighter, more flexible, and more efficient solar cell technologies suitable for practical use. Perovskite materials, which are defined by their crystalline structure, are better at absorbing light than silicon is. That means that perovskite solar cells can be thinner and lighter than silicon solar cells without sacrificing the cell’s ...

Cleveland Clinic study finds common artificial sweetener linked to higher rates of heart attack and stroke

Monday, February 27, 2023, Cleveland: New Cleveland Clinic research showed that erythritol, a popular artificial sweetener, is associated with an increased risk of heart attack and stroke. Findings were published today in Nature Medicine. Researchers studied over 4,000 people in the U.S. and Europe and found those with higher blood erythritol levels were at elevated risk of experiencing a major adverse cardiac event such as heart attack, stroke or death. They also examined the effects of adding erythritol to either whole blood or isolated platelets, which are cell fragments that clump together to stop bleeding and contribute to blood clots. Results revealed that ...

Association of cardiovascular health with life expectancy free of major chronic disease

About The Study: A high level of cardiovascular health (CVH) was associated with substantially longer life expectancy free of four major chronic diseases (cardiovascular disease, diabetes, cancer, and dementia) in both men and women in this study of 135,000 adults from the UK Biobank study. The disease-free life expectancy was similar between low and other socioeconomic groups among participants with high CVH. These findings support improvement in population health by promoting a high CVH level, which may also narrow health disparities associated with socioeconomic status.

Satellites observe speed-up of Glaciers on the Antarctic Peninsula

Glaciers - giant blocks of moving ice - along Antarctica’s coastline are flowing faster in the summer because of a combination of melting snow and warmer ocean waters, say researchers. On average, the glaciers travel at around one kilometre a year. But a new study has found a seasonal variation to the speed of the ice flow, which speeded up by up to 22 % in summer when temperatures are warmer. This gives an insight into the way climate change could affect the behaviour of glaciers and the role they could play in raising sea levels. Up to now, study of the rugged Antarctic peninsula ...

Cells avoid multitasking

Textbooks will tell you that in dividing cells, the production of new DNA peaks during the S-phase, while production of other macromolecules, such as proteins, lipids, and polysaccharides, continues at more or less the same level. Molecular biologists at the University of Groningen, led by professor Matthias Heinemann, have now discovered that this is not true: protein synthesis shows two peaks, and lipid synthesis peaks once. These shifts could explain the metabolic oscillations that lead up to cell division, ...

Chaos on the nanometer scale

Chaotic behavior is typically known from large systems: for example, from weather, from asteroids in space that are simultaneously attracted by several large celestial bodies, or from swinging pendulums that are coupled together. On the atomic scale, however, one does normally not encounter chaos – other effects predominate. Now, for the first time, scientists at TU Wien have been able to detect clear indications of chaos on the nanometer scale – in chemical reactions on tiny rhodium crystals. The results have been published in the journal ...
