When a heart attack damages the heart, the injured muscle is replaced by scar tissue. That scar can interfere with the electrical signals that coordinate each heartbeat, increasing the risk of dangerous rhythm disorders known as arrhythmias.

A new study reveals that the cardioprotective drug dexrazoxane significantly reduces heart damage caused by chemotherapy in pediatric cancer patients 15 years or more after treatment ends.

The prefrontal cortex, a brain region long associated with learning more flexible behaviors, can sometimes block the ability to think outside the box, a new study in mice shows. The finding by biologists at Emory University was published in Science Advances.

The dancing lights of fireflies and the eerie blue sparkle in crashing waves get their glow when a molecular square of carbon and oxygen atoms breaks. New research from Stanford University has shown that mechanical force can cause that break to happen in a way different from what

Bose-Einstein condensates (BECs) are often described as a "fifth state of matter": a quantum state in which many particles lose their individual identities and behave as one collective object. For more than 60 years, researchers have sought to create such condensates from exciton

How much ice is stored in the world's glaciers? And where exactly is it located? A new study led by Ca' Foscari University of Venice, in collaboration with the Institute of Polar Sciences of the National Research Council of Italy (CNR-ISP), provides an updated global map of glaci

New research reveals that cells of the same chronological age can follow dramatically different biological aging paths, offering new insights into cancer, neurodegeneration and the fundamental biology of aging. Rather than aging uniformly, tissues become a mosaic of biologically

An AI analysis of 1.2 million satellite images shows that floating algae blooms are spreading across the global ocean. The rapid growth of massive seaweed mats could reshape marine habitats while bringing foul-smelling decay, ecological damage, and economic losses to coastlines.

New research from Rutgers University–Newark psychologist Kent Harber reveals a strong connection between conspiracy theories, antisemitic attitudes and hostility toward Israel.

Microbial communities are highly sensitive to environmental changes, yet their enormous diversity makes it difficult to identify ecological patterns. A research team from the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) has shown that an AI method originally develop

The initiation of rain in clouds without ice remains one of the largest unsolved mysteries in atmospheric science. O recorte ajuda a contextualizar a pauta dentro de Ciência.

Senior Fifa duo pile pressure on under-fire presidentWenger reveals he knew nothing about investment planGianni Infantino’s authority was dealt a further blow after his No 2, the Fifa secretary general Mattias Grafström, called the failed World Cup private investment plan a “sad
