Researchers from 13 countries report a continent-wide warming effect on mountain plant communities in Europe, with species shifting towards those that prefer warmer temperatures. The findings suggest that this shift could lead to declines or even local disappearance of alpine plant species due to increased competition.
A team of scientists recreated the evolution of complexity in a molecular machine by analyzing ancient genes and testing their functions in modern organisms. They found that the increase in complexity was due to complementary loss of ancestral functions rather than gaining new ones.
A new study by NYU Langone Medical Center researchers identified netrin-1 as a molecule that blocks the normal migration of macrophages out of arteries, causing them to accumulate and promote atherosclerosis. Genetically deleting netrin-1 can minimize atherosclerosis, reduce macrophage levels in plaque, and promote macrophage migration.
A new test can identify biomarkers for mucopolysaccharidoses (MPS), a group of inherited metabolic disorders, allowing for earlier diagnosis and potentially more effective treatment. The test detects specific carbohydrate structures in cells, blood, and urine samples, enabling differentiation between forms of the disease.
A compound called AICAR has been found to prevent heat-induced deaths in mice with a gene mutation that makes them sensitive to heat. The study's findings suggest that AICAR could protect young athletes and soldiers from heat-related illnesses, potentially saving lives during exercise.
A new study suggests that Colorado's Rocky Mountains will experience a near elimination of surface hail by 2070. The warmer climate could lead to more runoff and an increased risk of flash floods. Meanwhile, intense storms may produce more hail inside clouds, but it will melt quickly and fall as rain.
Researchers investigated alternative nucleic acids that differ slightly from DNA and RNA, aiming to uncover a simpler genetic molecule. TNA, with its threose sugar backbone, showed promise as an early genetic carrier, folding into complex shapes that bind to targets with high affinity and specificity.
Researchers at the University of Texas created a new graphene form that is 60% more effective at managing and transferring heat than normal graphene. This breakthrough could lead to smaller, faster, and more powerful electronic devices with improved performance.
Current high levels of carbon dioxide are disrupting normal patterns of glaciation, delaying the next ice age by tens of thousands of years. This could lead to a significant increase in sea levels due to melting ice sheets.
A European study found that alpine meadows could disappear within decades due to climate change, with cold-loving species running out of mountains and being replaced by warm-loving ones.
Researchers at the University of Manchester have successfully made graphene magnetic by introducing vacancies and nonmagnetic atoms. The study's findings hold promise for future applications in spintronics and electronics, despite the tiny magnetism observed.
Researchers found that Crh and Oprm1 genes are implicated in anxiety and social behavior problems caused by excess MeCP2 protein in mice. Reducing levels of these genes alleviated symptoms, suggesting a potential treatment approach for patients with MeCP2 duplication syndrome.
A new study in Nature Climate Change presents a more complete picture of the climate costs of land use changes by incorporating biophysical effects beyond greenhouse gases. The researchers found that tropical rainforests are highly valuable for protecting against climate warming, while boreal forests have lower climate regulation values.
Researchers found that AICAR, an experimental therapy, protected animals from heat-induced sudden death and may hold promise for treating people with enhanced susceptibility to heat stroke. The drug works by reducing calcium leakage from RYR1, thus diminishing heat-induced contractions and muscle damage.
