A five-part hospital program made frail elderly heart patients stronger and less frail after one year.

A hospital program helped frail older heart patients get stronger and less frail after one year. The program combined exercise, health teaching, diet advice, gentle massage, and a check of their medicines. In a trial of 333 patients over age 70, those in the program scored better on frailty and physical tests than patients who got usual care. No serious harm from the program showed up during the study.

The number 333 patients over age 70

The size of the trial testing the multidisciplinary frailty program against usual hospital care.

One city, 333 patients, some dropped out before the end.

Eating a healthy diet, in general, was linked to slower biological aging in DNA.

People who score well on one healthy eating scale often do not score well on another. Despite this, most healthy diets were linked to slower signs of biological aging in the body's DNA. Different diets left different marks on DNA, but those marks tended to affect the same body processes. Both groups studied came from Germany. Results may not apply the same way elsewhere.

The number 10 diet quality scores compared

How much people's top scores overlapped across ten different healthy-eating measures.

Two German cohorts only, links not proof of cause.

Ocean carbon material holds locked-in water that keeps it from breaking down easily.

Ocean water holds a huge amount of dissolved carbon material. This material helps control Earth's carbon cycle. A heavy type of this material contains about 10% water locked tightly inside it. Mild heating removed this locked water and made the material easier for tiny ocean organisms to break down.

The number 10% by weight

The share of locked-in water found inside heavy ocean carbon material.

Lab samples only, not tested in the open ocean yet.

A cascade electric process makes glycolic acid from ethylene and oxygen with 62.9% energy efficiency.

A new electricity-powered method makes glycolic acid, an industrial chemical, without the dirty process factories use now. It links three chemical steps in a row and uses a byproduct made along the way, hydrogen peroxide, to help finish the job. The process turns starting materials into the wanted product 93.5% of the time and keeps 62.9% of the input energy in the final product.

The number 62.9% energy efficiency

The share of electrical energy that ends up stored in the final chemical product.

Lab-scale electrochemical test, not a running factory process yet.

A giant hydrogen gas cloud sits far from a known galaxy cluster, not inside it.

A huge, unexpected cloud of hydrogen gas was found far from a distant galaxy cluster, not inside it. The cloud stretched across a distance equal to about 40 million light years and was made of five separate pieces. One piece had unusually high levels of heavy elements. This may point to a hidden second cluster or to gas flowing in and out of a massive galaxy.

The number about 40 million light years across, five pieces

The size and structure of the unexpected hydrogen gas cloud found near a distant galaxy cluster.

One quasar sightline in the early universe, not a full 3D map.
