Birds' efficient red blood cells convert metabolic 'waste' into fuel for rapid recovery

New research finds that birds can use lactate, often thought of as a metabolic waste product, as a cellular fuel that aids in rapid recovery from a harmful state that impairs oxygen delivery. Hemoglobin, the protein that carries oxygen to our tissues, naturally converts to methem

From mother to offspring: Young birds show how 'forever chemicals' accumulate

New research has found young birds living near contaminated industrial and military sites in suburban Melbourne carry especially high concentrations of PFAS, so-called "forever chemicals."

Using quantum entanglement to secure ground-to-satellite timing

From mobile phones and banking systems to aircraft, ships and emergency services, much of modern life relies on precise timing signals from satellites. Known as the Global Navigation Satellite System (GNSS), satellites carrying atomic clocks transmit time-stamped signals to recei

Steering light in a flash: New chip redirects light beams in less than a trillionth of a s

Light can carry enormous amounts of information at extreme speeds, making photonic technologies promising for the development of faster communications, more powerful computing systems and more sensitive sensors. But for light to be useful for these purposes, engineers need to be

The oldest deliberately collected fossil ichthyosaur was discovered in Roman Britain aroun

Around 1,800 years ago, a fossilized spinal bone lay on the windswept beaches of Roman Britain until a curious passerby picked it up and carried it far away, only to drop it in a pit.

More than 90% of key nutrients degrading the Mar Menor lagoon come from recirculated under

More than 90% of the key nutrients degrading the Mar Menor, such as ammonium, phosphorus and silica, do not come from streams or continental groundwater, but rather through a mechanism that has so far been overlooked: Water from the lagoon itself infiltrates the sediments and re-

New probe could help trace Alzheimer's-linked lipids one cell at a time

Cells sitting side by side in the same tissues are not identical. Each cell carries its own subtly different chemical signature—a hidden individuality that can reveal how diseases take root and spread. Now, researchers from the University of Osaka have developed a technique sensi

Columbia scientists discover surprising link between serotonin and heart valve disease

Scientists have uncovered evidence that serotonin, the chemical best known for regulating mood, may also speed the progression of a common heart valve disease in some people. The research suggests that patients with degenerative mitral regurgitation who take SSRI antidepressants
