High-speed videos show what happens when a droplet splashes into a pool

Rain can freefall at speeds of up to 25 miles per hour. If the droplets land in a puddle or pond, they can form a crown-like splash that, with enough force, can dislodge any surface particles and launch them into

3 Questions: Exploring the limits of carbon sequestration

As part of a multi-pronged approach toward curbing the effects of greenhouse gas emissions, scientists seek to better understand the impact of rising carbon dioxide (CO2) levels on terrestrial ecosystems, particularly tropical forests. To that end, climate scientist César Terrer,

Chip-based system for terahertz waves could enable more efficient, sensitive electronics

The use of terahertz waves, which have shorter wavelengths and higher frequencies than radio waves, could enable faster data transmission, more precise medical imaging, and higher-resolution radar. But effectively generating terahertz waves using a semiconductor chip, which is essential for

Rooftop panels, EV chargers, and smart thermostats could chip in to boost power grid resilience

There’s a lot of untapped potential in our homes and vehicles that could be harnessed to reinforce local power grids and make them more resilient to unforeseen outages, a new study shows. In response to a cyber attack or natural

Reducing carbon emissions from residential heating: A pathway forward

In the race to reduce climate-warming carbon emissions, the buildings sector is falling behind. While carbon dioxide (CO2) emissions in the U.S. electric power sector dropped by 34 percent between 2005 and 2021, emissions in the building sector declined by

Unlocking the secrets of fusion’s core with AI-enhanced simulations

Creating and sustaining fusion reactions — essentially recreating star-like conditions on Earth — is extremely difficult, and Nathan Howard PhD ’12, a principal research scientist at the MIT Plasma Science and Fusion Center (PSFC), thinks it’s one of the most

Creating smart buildings with privacy-first sensors

Gaining a better understanding of how people move through the spaces where they live and work could make those spaces safer and more sustainable. But no one wants cameras watching them 24/7. Two former Media Lab researchers think they have

Puzzling out climate change

Shreyaa Raghavan’s journey into solving some of the world’s toughest challenges started with a simple love for puzzles. By high school, her knack for problem-solving naturally drew her to computer science. Through her participation in an entrepreneurship and leadership program,

Seeking climate connections among the oceans’ smallest organisms

Andrew Babbin tries to pack light for work trips. Along with the travel essentials, though, he also brings a roll each of electrical tape, duct tape, lab tape, a pack of cable ties, and some bungee cords. “It’s my MacGyver kit:

3 Questions: What the laws of physics tell us about CO2 removal

Human activities continue to pump billions of tons of carbon dioxide into the atmosphere each year, raising global temperatures and driving extreme weather events. As countries grapple with climate impacts and ways to significantly reduce carbon emissions, there have been
