Particles swirling around our atmosphere add to climate change, yet much about how they interact with sunlight and influence the seeding of clouds remains puzzling. Studies are lifting the lid on how these tiny particles influence something as big as climate by analysing them from jet aircraft, satellites and ground measurements.  The leading cause of climate change is rising levels of carbon dioxide in the […]

Cellular reprogramming can reverse the aging that leads to a decline in the activities and functions of mesenchymal stem/stromal cells (MSCs). This is something that scientists have known for a while. But what they had not figured out is which molecular mechanisms are responsible for this reversal. A study released today in STEM CELLS appears […]

It’s no surprise that most people in the U.S. don’t follow a healthy diet. But Stanford psychologists wanted to go deeper to find out why people don’t eat healthier even when they know it’s better for them. So they looked at an influential force in American popular culture – movies – to see how they […]

Most solar cells today are made with refined silicon that turns sunlight into clean electricity. Unfortunately, the process of refining silicon is far from clean, requiring vast amounts of energy from carbon-emitting power plants. For a greener alternative to silicon, researchers have focused on thin-film perovskites – low-cost, flexible solar cells that can be produced […]

Researchers at the Harvard Center for Population and Development Studies, Harvard Center for Geographic Analysis at the Institute for Quantitative Social Science, and Microsoft AI for Health have created a COVID-19 live tracker that monitors the current status of virus cases and deaths, as well as the reduction of new cases, in U.S. congressional districts. It is the first compilation of this […]

It’s hard to overstate how much of a game-changer it was when vertebrates first rose up from the waters and moved onshore about 390 million years ago. That transition led to the rise of the dinosaurs and all the land animals that exist today. “Being able to walk around on land essentially set the stage […]

Nanoparticles are promising drug delivery tools, offering the ability to administer drugs directly to a specific part of the body and avoid the awful side effects so often seen with chemotherapeutics. But there’s a problem. Nanoparticles struggle to get past the immune system’s first line of defense: proteins in the blood serum that tag potential […]

To see how deeply interconnected the planet truly is, look no further than the massive ice sheets on the Northern Hemisphere and South Pole. Thousands of miles apart, they are hardly next-door neighbors, but according to new research from a team of international scientists — led by Natalya Gomez, Ph.D. ’14, and including Harvard Professor Jerry […]
