Brown fat, or brown adipose tissue, is a type of body fat that burns calories to produce heat, which is the opposite of white fat, the tissue that stores extra calories. In adults it is usually found around the neck, armpits and chest. It helps newborns stay warm, and scientists once thought it disappeared after … Read more
Argon has 18 protons, matching its atomic number of 18; a neutral argon atom also has 18 electrons, and its most common isotope, argon-40, has 22 neutrons.
Dew point is the temperature where air becomes saturated (100% RH) and reflects actual moisture; relative humidity is a percentage that changes with temperature and can mislead how humid it feels.
Colossal Biosciences has not brought back the dodo, and it has not given a date for hatching a dodo-like bird. In an update on October 14, 2026, the Dallas company said its new AI tool, GenoMorph, had narrowed the search to about 2,300 candidate stretches of regulatory DNA linked to bird beak shape: 653 tied … Read more
Not necessarily. The names are often used interchangeably; biologists tell prawns and shrimps apart by their claws and abdominal segments, not by size.
The Large Physics Model is a planned AI foundation model for collider physics that CERN, Europe’s particle physics laboratory, and the French AI company Mistral announced on October 15, 2026, when they signed a statement of intent for a long-term partnership. CERN describes it as the first foundation model for collider physics: a single pretrained … Read more
Lactic acid fermentation produces lactic acid (lactate); alcohol fermentation by yeast produces ethanol and carbon dioxide. Both regenerate NAD+ so cells can keep making ATP without oxygen.
Yes. Brain tumours kill more children and adults under 40 in the UK than any other cancer, a point UK charities and the government repeated on October 14, 2026, when Prime Minister Andy Burnham met swimmer and campaigner Archie Goodburn and announced an expert review of brain cancer research, a national action plan, a new … Read more
Metagenomic testing sequences essentially all of the DNA and RNA in a clinical sample, then matches those genetic codes against large databases so doctors can identify bacteria, viruses, and other microbes—including ones not covered by routine single-pathogen tests. Hospitals increasingly use it for hard-to-diagnose infections such as unexplained meningitis or sepsis, and faster sequencers plus … Read more
Yes, in limited experimental settings: researchers can vitrify (cool into a glass-like state without ice) whole organs with cryoprotectant chemicals, store them at about −150 °C, then rewarm them with a technique called nanowarming. Iron oxide nanoparticles infused in the organ heat it evenly when an electromagnetic field is applied, which helps avoid cracking from … Read more
