Medical Xpress / Stable frontal signals, flexible hippocampal ones: How the brain preserves context as goals change
While humans are completing a task, they can temporarily store information in their minds while also manipulating and adapting it based on changing circumstances. To support this capability, known as working memory, the brain ...
Medical Xpress / Rare inherited EGFR mutation linked to dramatically increased lung cancer risk
A rare inherited mutation in the Epidermal Growth Factor Receptor (EGFR) gene is associated with a 25-fold increased risk of lung cancer, according to a study by investigators at Dana-Farber Cancer Institute and 23andMe Research ...
Phys.org / Wild honeybee populations in the EU are on the Red List for the first time
Populations of the Western honeybee (Apis mellifera) are under immense pressure in the wild in Europe. New research published in Conservation Science and Practice from the University of Hohenheim in Stuttgart and Agroscope ...
Phys.org / Weeping whales: Stillborn humpback whale grieving documented
Humpback whale mothers may experience grief when their calves die, a rare research observation led by Griffith University and Sea World Foundation has found.
Phys.org / Caffeine pollution could disrupt crustacean defenses against predators
While most people are aware of how plastic, arsenic and various industrial chemicals can pollute bodies of water, the effects of caffeine on freshwater environments remain largely unknown. Nonetheless, traces of caffeine, ...
Phys.org / Tendon cells can rebound from stiffness when returned to softer tissue-like surroundings
Researchers at Queen Mary University of London are closer to understanding tendinopathy, a common condition that can cause persistent pain and impaired movement in people and many animals.
Phys.org / Two spike 'keys' work together to let SARS-CoV-2 enter cells, study reveals
To enter cells, the COVID-19 virus fuses its surrounding membrane with the membrane of the target cell. This is where the fusion peptides of the spike protein come into play. These regions function as molecular keys that ...
Medical Xpress / A gut's complex architecture, recreated on a microscope slide–sized chip
Gut instinct, gut feeling or gutting it out—what exactly is the human gut? It's the workhorse of the digestive system and home to a vast, dynamic community of microorganisms that influence human health. In fact, the human ...
Medical Xpress / Scientists map brain's mysterious 'blue place' and discover longest neuron ever measured in a mouse
Deep in the brainstem sits a small but important cluster of neurons known as the locus coeruleus (LC), Latin for "blue place." It makes up a tiny fraction of the brain's cells but plays an important role by releasing the ...
Phys.org / Threatened bumblebee populations in England and Wales face severe genetic declines
A new study reveals that an important pollinator is rapidly losing genetic diversity in Britain. Moss carder bumblebees were once widespread across the UK, living in flower-rich meadows, marshes and heathlands, where they ...
Phys.org / Endurance running or endurance diving—which came first?
A new study combines paleoanthropology and diving physiology to address a fundamental question in human evolution: Why did humans evolve their exceptional aerobic endurance? Did our ancestors begin endurance running to exhaust ...
Phys.org / Handheld scanner delivers lab-quality chemical composition maps using infrared light
Researchers have developed a compact, handheld mid-infrared imaging spectrometer that can produce high-resolution chemical maps of a sample without using stains or labels. With further development, the handheld device might ...
