NASA’s New Horizons spacecraft took a series of images between 3 p.m. EST (8 p.m. GMT) on December 31, 2018, and 12:01 a.m. EST (5:01 a.m. GMT) on January 1, 2019, that were later linked together to make a movie showing the propeller-like rotation of the Kuiper Belt object Ultima …

Blood-forming (hematopoietic) adult stem cells reside deep in the bone marrow and are responsible for regenerating the body’s blood supply including red blood cells, white blood cells, and platelets. In a study published this week in the journal Cell Reports, a team of researchers from China and the United States …

According to a study published in the journal Immunity, fever alters surface proteins on immune cells to make them better able to travel via blood vessels to reach the site of infection. Fever is an evolutionarily conserved response in both endothermic and ectothermic species and confers survival benefits during infection …

A team of Canadian archaeologists has found a cache of charred seeds of the pitseed goosefoot (Chenopodium berlandieri spp. jonesianum), a form of quinoa native to Eastern North America, at the site of Tutela Heights in Brantford, Ontario. The ancient quinoa seeds date back to 930-915 BC, and have never …

  Science requires finesse, but sometimes it also needs more power. CERN took the latter approach when it built the Large Hadron Collider (LHC), a 17-mile (27 kilometers) particle accelerator that smashes protons together with so much energy they fracture into subatomic confetti. By studying the remnants of those collisions, …

An international team of researchers led by Queen’s University, Columbia University and the Federal University of Rio de Janeiro has found that irisin, a hormone released by muscles during exercise, could slow the progression of Alzheimer’s disease. Irisin is produced by muscles during exercise. Image credit: Free-Photos. “In the past …

Urolithin A, a major microbial metabolite derived from polyphenolic compounds of berries and pomegranate fruits, and its synthetic structural analog, can reduce and protect against inflammatory bowel diseases (ulcerative colitis or Crohn’s disease), according to new research from the University of Louisville and the Institute for Stem Cell Biology and …

A new study, published in the journal Menopause, shows that women receiving menopausal hormone therapy had a significantly lower prevalence of symptomatic knee osteoarthritis compared with women who did not take hormones. Knee osteoarthritis, also known as degenerative joint disease, is typically the result of wear and tear and progressive …

According to a theoretical paper published in the Annals of Physics, by Dr. Ovidiu Racorean from the General Direction of Information Technology in Bucharest, Romania, the geometry of spacetime around a rapidly spinning black hole (Kerr black hole) behaves like a quantum computer, and it can encode photons with quantum …

  The steam engine powered the industrial revolution, but humanity has long since moved beyond this archaic method of generating locomotion. However, we might not be done with steam power just yet. A team from the University of Central Florida (UCF) has constructed a prototype for a steam-powered space probe …
