Phys.org / Dry seeds preserve fully formed mitochondria, unlocking rapid energy at germination
The majority of plant seeds have the special ability to almost completely dry out and yet remain viable. While most living cells die with a 90% loss of water, cells in seeds enter a biological state of dormancy. With a moisture ...
Medical Xpress / Overuse of inhalers found to increase heart attack risk in asthma and COPD patients
Overuse of reliever inhalers is associated with higher risks of developing and dying from cardiovascular disease, including heart failure, heart attack and ischemic stroke, in patients with asthma and COPD, according to a ...
Phys.org / Fossil-fuel carbon fingerprint reaches the deep North Atlantic
The use of fossil fuels alters both the concentration and the carbon isotope composition of carbon dioxide in the atmosphere. Since surface water exchanges carbon dioxide with the atmosphere, this also alters the isotopic ...
Phys.org / We discovered rare dinosaur tracks from the Coniacian age near Tumbler Ridge, British Columbia
Imagine the Western Plains of North America, from Texas to Alaska, submerged under a broad, shallow seaway. To the west lay the ancestral Rocky Mountains. To the east were low-lying plains traversed by large, sluggish rivers.
Phys.org / Liquid gallium experiment confirms key flow regime inside rapidly rotating stars and planets
Since we cannot look into the interiors of stars and planets, we rely on lab experiments to replicate the physical processes that occur there. Led by the University of California, Los Angeles (UCLA), an international research ...
Phys.org / AI framework challenges student ideas early, helping undergraduates think critically about research
An interdisciplinary team of researchers has developed and demonstrated a step-by-step framework called Socratic Challenger that uses artificial intelligence to help undergraduate students cultivate critical thinking skills. ...
Medical Xpress / How much the immune system sees may shape how well we fight infections
Why does the same infection cause only mild symptoms in one person but more serious disease in another? A new study led by the HUN-REN BRC Szeged Momentum Systems Immunology Research Group, together with several international ...
Phys.org / Did ocean motion carve Enceladus's tiger stripes?
Saturn's moon Enceladus sports a thick shell of ice surrounding a liquid water ocean. As though scraped by an enormous claw, four parallel cracks slash across its south pole. Each about 500 meters (1,600 feet) deep, 2 kilometers ...
Phys.org / Narwhals help researchers uncover unique data from the deepest East Greenland fjords
They live in some of the most inaccessible waters on Earth, where ocean temperatures hover around freezing. Because they move through areas that humans rarely reach, they have been able to help researchers with a special ...
Medical Xpress / Cancer is quantum: Studies show cancer cells may occupy limited, shared states like quantized energy levels
Andrea Califano began his career as a physicist. But that's not why he's now calling cancer a quantum disease. "We're really just following the data," says Califano, the Clyde '56 and Helen Wu Professor of Chemical Biology ...
Phys.org / How plants evolved a molecular switch to cope with heat
As climate change drives more frequent and intense heat waves, plants face growing challenges to survive and remain productive. Researchers at VIB, Ghent University, KU Leuven and their international collaborators have uncovered ...
Phys.org / Does AI shape decisions before we do? Researcher questions what 'human in the loop' really means
Artificial intelligence is often discussed with a simple safeguard in mind: Keep a human in the loop. But what happens when AI is already shaping the information, options and recommendations that inform a decision?
