What does a region need to lead a discipline? Pioneers

To find out how many scientists a region needs to become a leader in a discipline, researchers tracked millions of scientists moving across the globe. Their result: there is no critical mass, but you have to be a pioneer. Regions can catch up later, but this costs a lot.

Singing supports stroke rehabilitation

Language function and the psychosocial wellbeing of patients and their families can be promoted with singing-based rehabilitation. Group intervention provides opportunities for peer support while being simultaneously cost effective.

Human brain organoids implanted into mouse cortex respond to visual stimuli for first time

A team of engineers and neuroscientists has demonstrated for the first time that human brain organoids implanted in mice have established functional connectivity to the animals' cortex and responded to external sensory stimuli. The implanted organoids reacted to visual stimuli in the same way as surrounding tissues, an observation that researchers were able to make in real time over several months...

Multi-institutional collaboration unveiling the mysteries of senescent cells and their effect on aging and human health

Researchers are bridging mouse and human data to reveal the biology of senescent cells. Senescent cells stop dividing in response to stressors and seemingly have a role to play in human health and the aging process. Recent research with mice suggests that clearing senescent cells delays the onset of age-related dysfunction and disease as well as all-cause mortality.

Alveolar macrophages help CD8+ T cells go (anti-)viral

Researchers have found that antigen-specific killer T cells (CD8+ T cells) rapidly expand in the lungs when primed by antigen-presenting lung-resident alveolar macrophages (AMs). This interaction helps protect against viral infection and could form the basis for developing 'cell transplant'-type vaccines in the future.

New biomarker test can detect Alzheimer's neurodegeneration in blood

The biomarker, called 'brain-derived tau,' or BD-tau, outperforms current blood diagnostic tests used to detect Alzheimer's-related neurodegeneration clinically. It is specific to Alzheimer's disease and correlates well with Alzheimer's neurodegeneration biomarkers in the cerebrospinal fluid. Scientists hope that monitoring blood levels of BD-tau could facilitate screening and enrollment of...

Skiing over Christmas holidays no longer guaranteed -- even with snow guns

For many people, holidays in the snow are as much a part of the end of the year as Christmas trees and fireworks. As global warming progresses, however, white slopes are becoming increasingly rare. Researchers have calculated how well one of Switzerland's largest ski resorts will remain snow reliable with technical snow-making by the year 2100, and how much water this snow will consume.

Ethereal color variant of mysterious plant is actually a new species

It was thought that there was only one species of the ghost-like Monotropastrum humile plant found in woodlands across East and Southeast Asia. In a major new discovery, botanists reveal that a rosy pink colored variant is actually a distinct new species, shaking up our understanding of this unusual-looking genus of plants. This 20-year study emphasizes the importance of combining various...

Eating viruses can power growth, reproduction of microorganism

Researchers have found that microscopic ciliates can eat huge numbers of infectious chloroviruses that share their aquatic habitat. The team's lab experiments have also shown that a virus-only diet, which the team calls 'virovory,' is enough to fuel the physiological growth and even population growth of an organism.

A checkerboard pattern of inner ear cells enables us to hear

A research group has revealed that the checkerboard-like arrangement of cells in the inner ear's organ of Corti is vital for hearing. The discovery gives a new insight into how hearing works from the perspective of cell self-organization and will also enable various hearing loss disorders to be better understood.
