Phys.org / Scientists find yeast in ancient Iceman's guts—and make bread
Yeast has been growing in the guts of a frozen mummy called Oetzi the Iceman for thousands of years, scientists have discovered, telling AFP they used it to make a tasty sourdough bread.
Medical Xpress / New obesity figures highlight the income divide
The number of obese adults in England rose from 26% in 2019 to 30% in 2025, according to a new analysis of 55 million people. Nearly 1 in 3 adults are now obese. But averages hide a lot, and behind this one are two very different ...
Medical Xpress / Survey suggests Europeans support state-funded fertility care and embryo research across 4 countries
A new Europe-wide survey launched during the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) suggests broad public support for fertility treatment and several areas of reproductive ...
Phys.org / Dangerous heat wave roasts America's big birthday party
A punishing heat wave threatened America's July Fourth celebrations, World Cup matches and power grids as near-record temperatures scorched the eastern United States on Friday.
Phys.org / Reanalysis suggests 'Phoebe' is a variable star, not a primordial black hole
A new study debunks a recent claim that astronomers may have detected a lunar-mass primordial black hole. In a reanalysis of observations from the Dark Energy Camera (DECam), researchers found that the star nicknamed "Phoebe" ...
Phys.org / Quantum gravity tests may mistake ordinary spacetime for superposition
Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful theories of physics: quantum mechanics and gravity. Quantum mechanics explains the behavior of the microscopic ...
Phys.org / Spontaneous current loops in a kagome metal point to hidden quantum order
Quantum materials, materials exhibiting physical behavior governed by the laws of quantum mechanics, have proved promising for the development of numerous advanced technologies, including quantum technologies, memory devices ...
Phys.org / Antarctic ozone loss drove unexpected Southern Ocean cooling, climate model shows
The Southern Ocean has long stood out as an oddity in the global climate system. While most of the planet's surface oceans have warmed in response to rising greenhouse gases, waters circling Antarctica showed an unexpected ...
Phys.org / What science tells us about the algae bloom in the Lincoln Memorial Reflecting Pool
Algal blooms in the Lincoln Memorial Reflecting Pool in Washington, D.C., have long been a visible public nuisance. When the pool turned green again on June 15, less than two weeks after President Donald Trump's US$14 million ...
Phys.org / Analog gravity advance offers new insights into Hawking radiation from black holes
Hawking radiation is a form of radiation emitted by black holes, as theoretically predicted by Stephen Hawking. It suggests that black holes do not merely swallow matter—as had previously been assumed—but also emit very faint ...
Phys.org / What makes a star a star? A strange 'in‑between' celestial object is testing astronomers' boundaries
A star called TOI-2155 lies around 1,350 light-years (839 trillion miles) from Earth. It is a little bigger, heavier and hotter than the sun, and it is not particularly interesting or unusual in itself.
Phys.org / Quantum semiconductor design could expand search for dark matter
Dark matter accounts for 85% of the matter in the universe, but scientists still do not know what it is made of. A study, published in Physical Review Letters, by Rice University researchers proposes a detector design that ...
