Phys.org / Machine learning rediscovers equations governing ocean biogeochemistry
Climate and ocean models use a series of equations to represent complex natural processes. However, the equations used in these models are often derived from limited observations and a series of assumptions.
Medical Xpress / Bandage-like device delivers hydrogen sulfide to wounds, boosting blood flow where healing stalls
For most people, a blister or small cut is an inconvenience. For others, it can become something much more serious.
Phys.org / Moose are native to Colorado, study shows
The modern Colorado moose is often considered just that: modern—brought to the state by wildlife officials in the late 1970s, preceded by very occasional reports of moose sightings in the 19th and early 20th centuries.
Phys.org / Did gravitational tides cause Earth's extinctions?
Life on Earth took a long evolutionary journey that eventually created us, the purportedly intelligent species that dominates the planet. But there was no grand plan or design, only happenstance, nature and luck. Life on ...
Phys.org / How oxygen sneaks into a corked wine bottle long before the first pour
The main reason for sealing wine bottles with a cork is to protect the liquid from oxygen. However, it is not an impermeable barrier, and a small amount of air leaks in, which is not always entirely bad news. The gas helps ...
Medical Xpress / Hidden thymus step may prime cancer-killing T cells earlier than expected
Researchers at Mayo Clinic have uncovered a previously hidden step in how the immune system prepares to fight cancer, a discovery that could help scientists develop more effective and longer-lasting cancer immunotherapies.
Phys.org / Scientists discover 'hyperparasite' in Malaysia Borneo jungle
Malaysian scientists have discovered a new species of parasitic fungus in Borneo's jungles that preys on "zombie fungi" known to infect insects before subjecting them to a gruesome death.
Phys.org / Oldest known asteroid impact on Earth dated to 3 billion years
Curtin University researchers have determined the most precise age yet for the oldest known impact crater on Earth, providing new insight into how meteorite strikes shaped the planet during its earliest history.
Phys.org / Study explores environmental cost, perceptions of influencer PR gifts
As part of their marketing strategy, many companies send public relations packages full of curated products to social media influencers, who film themselves opening the gifts on platforms like Instagram and TikTok.
Phys.org / Fiber-optic cables detect silent whales off Svalbard by tracking pressure waves
A 100-year-old equation and a fiber-optic cable off the coast of Svalbard led researchers to discover they could detect swimming whales—even if they were completely silent. The discovery broadens the tools biologists could ...
Phys.org / Plasma approach keeps catalysts working for longer in hydrogen production
Scientists from the University of Manchester have shown how a plasma-based approach, using nonthermal plasma—an electrically energized gas often described as the fourth state of matter—can prevent catalyst deactivation in ...
Phys.org / How to create the perfect wing shot in handball
Dare to jump up close to the defender, aim for a long jump distance, and use your time in the air to read the game. These are some of the keys to the perfect wing shot in handball, according to a bachelor's thesis from Chalmers ...
