More yield, fewer species: How human nutrient inputs alter grasslands

One of the reasons for the global threat to biodiversity is that we humans introduce more nutrients into our environment than would naturally be present there, for example, when fertilizing agricultural land. In addition, precipitation re-distributes excess nutrients to other areas, and nutrients can also enter our soils through air pollution.

Scientists map water in molecular crystals, aiding drug development

Molecular crystals—the building blocks that make up many drugs and other products—sometimes take on water molecules, which can alter the crystals in unforeseen ways. Notably, predicting which crystals are likely to contain water and at what level has been difficult and very computationally intensive. This problem is of significant industrial interest, especially in pharmaceuticals, yet the immense challenges associated with it require novel and efficient approaches.

Different blossoming schedules have kept these flowers from driving each other extinct

A big part of evolution is competition— when there are limited resources to go around, plants and animals have to duke it out for nutrients, mates, and places to live. That means that the flower-covered meadows of China's Hengduan mountains were an evolutionary mystery— there are dozens of species of closely-related rhododendrons that all live in harmony. To figure out why, scientists spent a summer carefully documenting the flowering patterns of 34 Rhododendron species, and they discovered the reason why the plants were able to coexist: they burst into bloom at different points in the season so they don't have to compete for pollinators.

Significantly more adults with dermatomyositis receiving intravenous immune globulin (IVIG) versus placebo have a response of at least minimal improvement, according to a study published in the Oct. 6 issue of the New England Journal of Medicine.

A one-stop-shop for brain imaging

The brain is a complex organ, and no one imaging mode can catch everything that's going on inside it. Over the years, multiple "brain maps" have emerged, each focusing on different brain processes, from metabolism to cognitive function. While these maps are important, using them in isolation limits the discoveries researchers can make from them.

Video games offer the potential of 'experiential medicine'

After a decade of work, scientists at UC San Francisco's Neuroscape Center have developed a suite of video game interventions that improve key aspects of cognition in aging adults.

No significant increase in Guillain-Barré syndrome after COVID-19 vaccination, researchers find

There is no evidence that the COVID-19 vaccination increases the incidence of Guillain-Barré syndrome, a rare neurological disorder in which the body's immune system attacks the nerves, according to a Rutgers-led study.

Psychological factors contribute to biological aging: Evidence from the aging rate in Chinese older adults

Aging clocks are statistical models that enable measurements of biological age, as opposed to chronological age. While the latter is determined by one's date of birth, the former depends on the intensity of aging processes and can be affected by genetics, life choices, and the environment. Most commonly, such aging clocks are regressors, trained to predict a person's chronological age based on a vector of input parameters, such as clinical blood test results, gene expression levels, or DNA methylation intensities.

Study reveals main target of SARS-CoV-2 in brain and describes effects of virus on nervous system

A Brazilian study published in the journal PNAS describes some of the effects infection by SARS-CoV-2 can have on the central nervous system. A preliminary version (not yet peer-reviewed) posted in 2020 was one of the first to show that the virus that causes COVID-19 can infect brain cells, especially astrocytes. It also broke new ground by describing alterations in the structure of the cortex, the most neuron-rich brain region, even in cases of mild COVID-19.

Better Asthma and COPD Drugs with Fewer Side Effects Are Within Reach

Bronchodilators, the most common type of asthma-fighting drug, inhibits contractions of airway smooth muscle that are induced by stimulating receptors on the muscle's surface. New research highlights a novel mechanism for the drugs and will aid in the development of better medications for the treatment of asthma and chronic obstructive pulmonary disease (COPD). The findings are detailed in a new article by researchers from Dundalk Institute of Technology in Ireland and Queen's University in Northern Ireland.

Study advances knowledge of role of brain pathology and cognitive fatigue in multiple sclerosis

Using advanced diffusion neuroimaging technology, Kessler Foundation researchers investigated the relationship between the rate of cognitive fatigue to microstructural changes in the brain in persons with multiple sclerosis. Their findings help fill a gap in the current understanding of how brain pathology influences the development of fatigue over time.
