Overlooked cell type orchestrates brain rewiring

Posted 2025-05-16 17:48:34 by: Admin

Researchers have shown in mice that brain cells known as astrocytes are required for a signaling chemical called norepinephrine to modify brain activity, changing the textbook understanding that norepinephrine acts directly on ...

New auditory brainstem implant shows early promise

Posted 2025-05-16 17:42:45 by: Admin

Investigators are developing a new type of auditory brainstem implant that is designed to be soft, and flexible and address limitations of models currently in use. These implants may one day benefit people who can't receive a cochlear implant, such as those with Neurofibromatosis type 2 (NF2) and other severe inner ear abnormalities. In a new preclinical study, researchers report on benefits in large animal models, and based on the results, hope for future trials in ...

Study reveals a deep brain region that links the senses

Posted 2025-05-15 23:11:40 by: Admin

Humans perceive and navigate the world around us with the help of our five senses: sight, hearing, touch, taste and smell. And while scientists have long known that these different senses activate different parts of the brain, a new study indicates that multiple senses all stimulate a critical region deep in the brain that controls consciousness. The study sheds new light on how sensory perception works in the brain and may fuel the development of therapies to treat disorders involving attention, arousal, and ...

Asians made humanity's longest prehistoric migration and shaped the genetic landscape in the Americas

Posted 2025-05-15 18:15:49 by: Admin

An international genomics study has revealed that early Asians undertook humanity's longest known prehistoric migration. These early humans, who roamed the earth over 100,000 years ago, are believed to have traveled more than 20,000 kilometers on foot from North Asia to the southernmost tip of South America. Scientists have mapped the unexpectedly vast genetic diversity of Asians, who make up more than half of the world's population. These findings overturn long-held assumptions of European genetic dominance and show that native South Americans are of Asian descent. The study also sheds light on how such a vast migration and differing environments have shaped human evolution, including how populations have adapted to diseases and how their immune systems have ...

World's largest bat organoid platform paves the way for pandemic preparedness

Posted 2025-05-15 18:15:41 by: Admin

Until now, most research has used either generalized cell samples or organoids made from just one type of tropical fruit bat, and only from a single organ. But a breakthrough has arrived: a research team has now created the world's most comprehensive bat organoid platform. These 'mini-organs' are grown from five common bat species found across Asia and Europe and represent four different organs - airway, lungs, kidneys, and small ...
