To promote exercise, planners must look beyond cities
2023-02-27
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
2023-02-27
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 ...

Plugging immune cell leakage from tumors could improve skin cancer treatment
2023-02-27
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
2023-02-27
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
2023-02-27
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
2023-02-27
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
2023-02-27
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
2023-02-27
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
2023-02-27
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 ...
