No solo los mayores están en riesgo. Más de tres cuartas partes de las muertes relacionadas con el calor en el país se produjeron entre personas menores de 35 años, reveló un estudio reciente.

It’s not just the elderly. More than three-quarters of heat-related deaths in Mexico occurred among people younger than 35, researchers reported.

Federal health agencies closed their investigations into the bacterial outbreak that sickened 104 people and was linked to onions on the fast-food chain’s signature Quarter Pounders.

The agency long benefited from broad bipartisan support. But Republican criticism has intensified, and new choices for top health posts hope to upend the organization.

Cassava Sciences said that its drug did not significantly reduce cognitive decline in 1,900 people with mild to moderate Alzheimer’s disease.

Journals had retracted papers on superconductors that worked at room temperature and materials science that involved Ranga Dias.

A sharp partisan divide remains over how involved researchers should be in policy decisions.

The company said it would put Quarter Pounders back on the menu, without the raw onions that were considered the likely source of the bacteria.

Health officials say that recalls of onions — the suspected source of the contamination — would help lessen the risk to consumers. Other major fast-food chains have also stopped offering onions.

A deadly outbreak spurred removal of onions by a major food supplier in the Mountain West. Taco Bell, KFC, Burger King and Pizza Hut have stopped serving onions at various locations.
