It is well understood how flowers use complex color patterns and smells to attract pollinating bees. But now, scientists have discovered that flowers also emit heat to advertise themselves to insects — creating temperature arrays that mimic the color designs of petals.On average, heat spots were 4 to 5 degrees Celsius warmer than the rest of the…

Scientists at Michigan State University have shown that streams can be key health indicators of a region’s landscape, but the way they’re being monitored can be improved.New research featured in Ecology Letters showcases how streams can be used as sensors to diagnose a watershed’s sensitivity or resiliency to changes in land use practices, including the…

Forty percent of the world’s 2.5 billion people live in coastal cities and towns. A team including Smithsonian marine biologists just released 25 years of data about the health of Caribbean coasts from the Caribbean Coastal Marine Productivity Program (CARICOMP). The study provides new insights into the influence of both local and global stressors in…

As Tropical Cyclone Hilda was coming together in the Southern Indian Ocean the GPM satellite analyzed its rainfall from space. On December 26, 2017 at 3:06 a.m. EST (0806 UTC) the Global Precipitation Measurement mission or GPM core observatory satellite flew above northwestern Australia and measured rainfall as Tropical Cyclone Hilda was forming along the coast

Many of the more than 200 remote communities in Alaska are turning to renewable energy to reduce reliance on high-cost imported fuels, and to ensure more independent and reliable energy availability based on local sources. Alaska is home to a substantial fraction of the developed microgrids in the world. Incorporating grid-scale levels of renewably sourced…

Naturally occurring algae on Greenland’s massive ice sheet absorb large amounts of the sun’s energy and speed up the melting of the ice sheet even more than black carbon and mineral dust, according to a new study.

Short-term exposures to fine particulate air pollution and ozone—even at levels well below current national safety standards—were linked to higher risk of premature death among the elderly in the U.S. according to a new study from Harvard T.H. Chan School of Public Health.The risk was even higher among elderly who were low-income, female, or Black.The study was…

Cities plagued with terrible traffic problems may be overlooking a simple, low-cost solution: High-occupancy vehicle (HOV) policies that encourage carpooling can reduce traffic drastically, according to a new study co-authored by MIT economists.

Charcoal remains after a forest fire help decompose fine roots in the soil, potentially accelerating CO2 emissions in boreal forests.
