Physicists rewrite Einstein’s equations to define spacetime evolution

Spacetime is often described as the stage on which the universe unfolds, a four-dimensional blend of space and time that bends, stretches and shifts as matter and energy move through it. However, despite more than a century of work since Einstein introduced general relativity, physicists still struggle to describe how that stage evolves when gravity becomes violent, nonlinear and hard to predict.

146,000-year-old tools suggest human ingenuity thrived during the ice age

A deer rib pulled from an ancient butchery site in central China carried an unexpected clue. Inside the bone, calcite crystals had grown over time, and those crystals turned out to be a kind of clock.

8,500 steps a day can help keep the weight off after dieting [af]

A step counter will not do the hard part of dieting for you. But new research suggests it may help with the part many people struggle with most, keeping the weight off once it is gone.

Research breakthrough reveals the secret behind blood clotting

Blood clotting depends on speed, force, and timing. Platelets have to stay quiet while circulating through the body, then switch into action fast when a blood vessel breaks. A new look inside that system shows, in unusually fine detail, how one of its key molecular motors stays shut down until the moment it is needed.

At-home blood and brain tests revolutionize early dementia screening

A blood sample small enough to come from a finger prick, paired with a set of online thinking tests, may offer a new way to sort who faces the greatest risk of dementia.

Eggs have spent years in nutrition debates, praised for protein one moment and questioned for cholesterol the next. Now a large, long-running study suggests they may also be tied to something else: a lower chance of being diagnosed with Alzheimer’s disease later in life.

JWST finds a heavy atmosphere on a mini-Neptune orbiting a hot Jupiter

A giant planet was supposed to have the place to itself. Instead, in a star system 190 light-years away, a hot Jupiter shares space with a much smaller world, a mini-Neptune tucked even closer to the star. That pairing is rare enough on its own. Now, a fresh look at the smaller planet’s atmosphere is giving astronomers a clue to how both worlds may have ended up there.

The light from LHS 3844 b does not suggest oceans, clouds, or even air. What it points to instead is a dark, battered surface. This surface may have more in common with Mercury or the Moon than with anything you would recognize from Earth.

Quantum technology often gets pitched as a faster kind of computing. This research points in a different direction first: control. By changing a magnetic field on a schedule, rather than leaving it fixed, physicists found they could make matter settle into quantum states that do not exist in ordinary stationary materials.
