Researchers have completed the first-ever activity map of a mammalian brain in a groundbreaking duo of studies, and it has rewritten scientists’ understanding of how decisions are made. The project, involving a dozen labs and data from over 600,000 individual mouse brain cells, covered areas representing over 95% of the brain. Findings from the research, published in two papers in …

Depriving brain tumours of an amino acid could enhance chemotherapy  Nature Source link

A highly lethal type of brain tumour often steals key nutrients to aid its aggressive growth — a habit that can be exploited to slow the cancer’s spread, scientists have found1. Experiments show that many brain tumours called glioblastomas grab serine, a crucial amino acid, from their environment rather than synthesizing it themselves: a metabolic Achilles’ heel. The scientists fed …

A protein called ferritin light chain 1 (FTL1) may play a significant role in brain aging, a new study reveals, giving scientists a new target for understanding and potentially preventing brain deterioration and disease. FTL1 was brought to light through a careful comparison of the hippocampus part of the brain in mice of different ages. The hippocampus is involved in …

Summary: A new study shows that chronic stress causes immune cells called neutrophils to leave bone marrow in the skull and collect in the brain’s protective membranes, where they contribute to depressive symptoms. In mice, blocking an immune “alarm” pathway reduced these cells and improved mood-related behaviors. The findings highlight how stress reshapes the brain’s immune environment and suggest why …

The performance of non-invasive brain devices can be improved by combining them with AI.Credit: Jean-Pierre Clatot/AFP via Getty A man with partial paralysis was able to operate a robotic arm when he used a non-invasive brain device partially controlled by artificial intelligence (AI), a study reports1. The AI-enabled device also allowed the man to perform screen-based tasks four times better …

Fossils usually leave us with bones turned to stone, the hard remains of creatures long gone. But every so often, nature offers something far rarer — a glimpse of soft tissue that survived for millions of years. Researchers examining a 520-million-year-old arthropod larva were stunned to find not just an outline of the creature, but an interior anatomy preserved with …
