Dark chocolate has been extensively studied for its cardiometabolic health benefits, but findings have been inconsistent, spurring heated debates over whether this treat has pros that outweigh the cons. Now, new research puts dark chocolate back on the table, quantifying its impact on type 2 diabetes risk and weight gain in a study of nearly 200,000 US adults.

Ever been caught in the crossfire of a wet dog firing droplets of water away from their fur with a mad shake? Well, they can't help it. Scientists have identified the innate sense-motor function mechanism that drives dogs to twist and spout.

Treating life-threatening bloodstream infections in combat situations is challenging, especially when the pathogen responsible is unknown. So, DARPA has called on Harvard’s Wyss Institute to use its groundbreaking biotech to fight this deadly threat.

In a medical emergency, quick treatment is critical. But a widely used drug could be repurposed to induce a hibernation-like state, to slow down organ damage and save lives by giving patients more time to reach a hospital.

While cochlear implants do allow some deaf people to hear, they also incorporate potentially problematic external components located on the side of the head. That could soon change, however, thanks to an experimental new implantable microphone.

Scientists at Harvard have developed a promising new treatment to reverse hair loss associated with alopecia. Painless microneedle patches loaded with an immune regulating drug regrew hair in mice with alopecia within a few weeks.

Earth’s seasons change as we orbit the Sun – but can the climate also be affected by the solar system’s changing position in the Milky Way? A new study suggests an ice age about two million years ago may have been triggered by an interstellar winter.

Harvard and Google Research have mapped thousands of cells and millions of synapses in a poppy seed-sized sample of tissue. The result is a set of truly stunning images and marks a major step towards understanding of the biggest challenges in science.

The 2024 QS World University Rankings were released this week, and with three new key metrics added to the scoring process, several universities have rocketed to the international forefront, while traditional icons are being pushed below the fold.

Harvard engineers have created a strange new “metafluid” – a liquid that can be programmed to change properties, like its compressibility, transparency, viscosity and even whether it’s Newtonian or not.

While there are already apps that guide blind users to a bus stop's GPS coordinates, those people may unknowingly end up standing too far away from the actual stop. A new app addresses that shortcoming, by letting the phone's camera in on the act.

A breakthrough clinical trial using gene therapy has restored hearing to five children born deaf. After six months, the children were able to recognize speech and hold conversations, raising hopes for wider use in the near future.
