Correcting Historic Sea Surface Temperature Measurements

Jul 17, 2019 04:18 PM EDT

Something odd happened in the oceans in the early 20th century. The North Atlantic and Northeast Pacific appeared to warm twice as much as the global average while the Northwest Pacific cooled over several decades.

Climate Warming Could Increase Malaria Risk in Cooler Regions

Jun 27, 2019 11:35 AM EDT

Malaria parasites develop faster in mosquitoes at lower temperatures than previously thought, according to researchers at Penn State and the University of Exeter. The findings suggest that even slight climate warming could increase malaria risk to hundreds of thousands, if not millions, of people including travelers in areas that are currently too cold for malaria parasites to complete their development.

Fresh Look at Mysterious Nasca Lines in Peru

Jun 21, 2019 02:41 PM EDT

A scientific approach has been used to re-identify huge birds etched into the desert plains of southern Peru around 2,000 years ago. The birds appear to be exotic to the region and further studies could help explain their significance. The study is published in the Journal of Archaeological Science: Reports.

Gemini Planet Imager Analyzes 300 Stars

Jun 12, 2019 04:15 PM EDT

Over the past four years, an instrument attached to a telescope in the Chilean Andes - known as the Gemini Planet Imager - has set its gaze on 531 stars in search of new planets. The team, led by Stanford University, is now releasing initial findings from the first half of the survey, published June 12 in The Astronomical Journal.

Measuring Methane From Coal and Gas in Pennsylvania Informative

May 24, 2019 10:45 AM EDT

While methane pollution caused by natural gas production in Pennsylvania is underestimated by the U.S. Environmental Protection Agency, natural gas still has half the carbon footprint of underground coal mining, according to an international team of researchers.

Oldest Meteorite Collection on Earth Found in One of the Driest Places

May 23, 2019 02:16 PM EDT

Boulder, Colo., USA: Earth is bombarded every year by rocky debris, but the rate of incoming meteorites can change over time. Finding enough meteorites scattered on the planet's surface can be challenging, especially if you are interested in reconstructing how frequently they land. Now, researchers have uncovered a wealth of well-preserved meteorites that allowed them to reconstruct the rate of falling meteorites over the past two million years.

Intensive Silviculture Accelerates Atlantic Rainforest Biodiversity Regeneration

May 18, 2019 11:35 AM EDT

An experiment conducted in Brazil in an area of Atlantic Rainforest suggests that intensive silviculture, including the use of herbicide and substantial amounts of fertilizer, is a more effective approach to promoting the regeneration of tropical forest and biomass gain than the traditional method based on manual weeding and less fertilizer.

Galaxy Blazes with New stars Born From Close Encounter

May 17, 2019 10:19 AM EDT

The irregular galaxy NGC 4485 shows all the signs of having been involved in a hit-and-run accident with a bypassing galaxy. Rather than destroying the galaxy, the chance encounter is spawning a new generation of stars, and presumably planets.

Small, Hardy Planets Most Likely to Survive Death of Their Stars

May 15, 2019 12:31 PM EDT

Small, hardy planets packed with dense elements have the best chance of avoiding being crushed and swallowed up when their host star dies, new research from the University of Warwick has found.

Iceland Volcano Eruption in 1783-84 Did Not Spawn Extreme Heat Wave

May 15, 2019 12:00 PM EDT

An enormous volcanic eruption on Iceland in 1783-84 did not cause an extreme summer heat wave in Europe. But, as Benjamin Franklin speculated, the eruption triggered an unusually cold winter, according to a Rutgers-led study.

The Moon is Quaking as It Shrinks

May 13, 2019 04:56 PM EDT

A 2010 analysis of imagery from NASA's Lunar Reconnaissance Orbiter (LRO) found that the moon shriveled like a raisin as its interior cooled, leaving behind thousands of cliffs called thrust faults on the moon's surface.

WASHINGTON, D.C. May 1, 2019 - Back in 2013, Timothy Koeth, an associate research professor at the University of Maryland, received a rather extraordinary birthday gift: a little cloth lunch pouch containing a small object wrapped in brown paper towels.

Scientists Develop Low-cost Energy-efficient Materials

Apr 24, 2019 10:19 AM EDT

An international team of scientists from the National University of Science and Technology "MISIS" (NUST MISIS), Tianjin University (China), as well as from Japan and the United States has developed new energy-efficient iron-based alloys which combine high mechanical and magnetic properties with low cost and open up new opportunities for industry.

A Closer Look at Mercury's Spin and Gravity Reveals the Planet's Inner Solid Core

Apr 18, 2019 08:59 PM EDT

How do you explore the interior of a planet without ever touching down on it? Start by watching the way the planet spins, then measure how your spacecraft orbits it -- very, very carefully. This is exactly what NASA planetary scientists did, using data from the agency's former mission to Mercury.

Western bias in human genetic studies is 'both scientifically damaging and unfair'

Mar 22, 2019 07:59 AM EDT

Despite efforts to include more diversity in research, people of European ancestry continue to be vastly overrepresented and ethnically diverse populations largely excluded from human genomics research, according to the authors of a commentary published March 21 in a special issue of the journal Cell on human genetics.
