    How plants protect themselves from sun damage

    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

    Machine learning picks out hidden vibrations from earthquake data

    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

    Deep cuts in greenhouse emissions are tough but doable, experts say

    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

    MIT-powered climate resilience solution among top 100 proposals for MacArthur $100 million grant

    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

    Instrument may enable mail-in testing to detect heavy metals in water

    Lead, arsenic, and other heavy metals are increasingly present in water systems around the world due to human activities, such as pesticide use and, more recently, the inadequate disposal of electronic waste. Chronic exposure to even trace levels of these contaminants, at concentrations of parts per billion, can cause debilitating health conditions in pregnant women, […] More

    Mars 2020: The search for ancient life is on

    Planetary scientists believe that Mars was once warmer, had a significant atmosphere, and maintained abundant flowing water that carved out river channels and pooled in lakes. These conditions would, at least theoretically, support life. But following a July 2020 launch, a 34 million mile journey, and an elaborately choreographed descent though the scant Martian atmosphere, […] More

    Seeding oceans with iron may not impact climate change

    Historically, the oceans have done much of the planet’s heavy lifting when it comes to sequestering carbon dioxide from the atmosphere. Microscopic organisms known collectively as phytoplankton, which grow throughout the sunlit surface oceans and absorb carbon dioxide through photosynthesis, are a key player. To help stem escalating carbon dioxide emissions produced by the burning […] More
