As flowers bloom and fruits ripen, they emit a colorless, sweet-smelling gas called ethylene. MIT chemists have now created a tiny sensor that can detect this gas in concentrations as low as 15 parts per billion, which they believe could be useful in preventing food spoilage. The sensor, which is made from semiconducting cylinders called […] More
In 2016, scientists at MIT and elsewhere observed the first signs of healing in the Antarctic ozone layer. This environmental milestone was the result of decades of concerted effort by nearly every country in the world, which collectively signed on to the Montreal Protocol. These countries pledged to protect the ozone layer by phasing out […] More
Over millions of years, Hawaiian volcanoes have formed a chain of volcanic islands stretching across the Northern Pacific, where ocean waves from every direction, stirred up by distant storms or carried in on tradewinds, have battered and shaped the islands’ coastlines to varying degrees. Now researchers at MIT and elsewhere have found that, in Hawaii, […] More
For plants, sunlight can be a double-edged sword. They need it to drive photosynthesis, the process that allows them to store solar energy as sugar molecules, but too much sun can dehydrate and damage their leaves. A primary strategy that plants use to protect themselves from this kind of photodamage is to dissipate the extra […] More
Over the last century, scientists have developed methods to map the structures within the Earth’s crust, in order to identify resources such as oil reserves, geothermal sources, and, more recently, reservoirs where excess carbon dioxide could potentially be sequestered. They do so by tracking seismic waves that are produced naturally by earthquakes or artificially via […] More
How can the world cut its greenhouse gas emissions in time to avert the most catastrophic impacts of global climate change? It won’t be easy, but there are reasons to be optimistic that the problems can still be solved if the right kind of significant actions are taken within the next few years, according to […] More
On Feb. 25, MIT Solve launched its 2020 Global Challenges: Good Jobs and Inclusive Entrepreneurship, Learning for Girls and Women, Maternal and Newborn Health, and Sustainable Food Systems, with over $1 million in prize funding available across the challenges. Solve seeks tech-based solutions from social entrepreneurs around the world that address these four challenges. Anyone, anywhere can […] More
The John D. and Catherine T. MacArthur Foundation unveiled that a proactive climate resilience system co-developed by MIT and BRAC, a leading development organization, was one of the highest-scoring proposals, designated as the Top 100, in its 100&Change competition in 2020 for a single $100 million grant to help solve one of the world’s most […] More
