Hubble weighs in on mass of 3 million billion suns

Tue, 16 Jan 18 00:00:30 -0800

In 2014, astronomers using the NASA/ESA Hubble Space Telescope found that this enormous galaxy cluster contains the mass of a staggering three million billion suns. Known officially as ACT-CLJ0102-4915, it is the largest, hottest, and brightest X-ray galaxy cluster ever discovered in the distant universe.



In sweet corn, workhorses win

Tue, 16 Jan 18 00:04:50 -0800

When deciding which sweet corn hybrids to plant, vegetable processors need to consider whether they want their contract growers using a workhorse or a racehorse. Is it better to choose a hybrid with exceptional yields under ideal growing conditions (i.e., the racehorse) or one that performs consistently well across ideal and less-than-ideal conditions (i.e., the workhorse)? New research from the University of Illinois suggests the workhorse is the winner in processing sweet corn.



Weather anomalies accelerate the melting of sea ice

Tue, 16 Jan 18 00:05:30 -0800

ETH researchers reveal why Arctic sea ice began to melt in the middle of winter two years ago -- and that the increased melting of ice in summer is linked to recurring periods of fair weather.



Jet stream changes since 1960s linked to more extreme weather

Fri, 12 Jan 18 00:04:00 -0800

Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves, wildfires and flooding. The new research published in Nature Communications is the first reconstruction of historical changes in the North Atlantic jet stream prior to the 20th century. By using tree rings, the researchers developed a historical look at the position of the North Atlantic jet back to 1725.



Tropical Cyclone Joyce makes landfall on Australia's Pilbara Coast

Fri, 12 Jan 18 00:09:40 -0800

NOAA's JPSS-1 satellite provided a visible image of the tropical storm after it made landfall along the Pilbara Coast in the northwestern part of Western Australia.



Why the Republican Party may have an advantage when it rains: Voters change their minds

Thu, 11 Jan 18 00:04:40 -0800

Bad weather affects US voter turnout and election outcomes with past research demonstrating that the Republican Party has the advantage. A new study by researchers at Dartmouth College and The Australian National University finds that the Republican Party's advantage when it rains may be due in part to voters changing their partisan preference that day.



Urban insects are more resilient in extreme weather

Thu, 11 Jan 18 00:05:50 -0800

A study led by Amy Savage, a Rutgers University-Camden assistant professor of biology, will help researchers understand how to make predictions and conservation decisions about how organisms living in cities will respond to catastrophic weather events.



Tracing how disaster impacts escalate will improve emergency responses

Thu, 11 Jan 18 00:08:10 -0800

Mapping common pathways along which the effects of natural and man-made disasters travel allows more flexible and resilient responses in the future, according to UCL researchers.



The brain's GPS has a buddy system

Thu, 11 Jan 18 00:15:30 -0800

Brain cells that reflect self position relative to others have been identified in the rat hippocampus. Sometimes these representations are processed jointly by the same cells, depending on a rat's goals and actions. This discovery, from Japan's RIKEN Brain Science Institute, deepens our understanding of the hippocampus and its role as the brain's positioning system.



Organic molecule benzonitrile detected in space

Thu, 11 Jan 18 00:15:10 -0800

Scientists studying a cold molecular cloud of the Taurus region with radio telescopes have detected the presence of a particular organic molecule called benzonitrile. The finding marks the first time a specific aromatic molecule has been identified in space using radio spectroscopy.



GBT detection unlocks exploration of 'aromatic' interstellar chemistry

Thu, 11 Jan 18 00:14:10 -0800

Astronomers using the Green Bank Telescope have made the first definitive interstellar detection of benzonitrile, an intriguing organic molecule that helps to chemically link simple carbon-based molecules and truly massive ones known as polycyclic aromatic hydrocarbons. This discovery is a vital clue in a 30-year-old mystery: identifying the source of a faint infrared glow that permeates the Milky Way and other galaxies.



Emergency department program for older adults cuts hospitalizations by 33 percent

Thu, 11 Jan 18 00:00:10 -0800

Roughly one third of all older patients age 65 and older visiting emergency departments nationwide are admitted to the hospital. But an emergency department program focused on geriatric transitional care has reduced the risk of unnecessary admission of older patients at Northwestern Medicine by 33 percent, according to a new study from Northwestern Univeristy, Mount Sinai Medical Center and St. Joseph's Regional Medical Center.



Hubble finds substellar objects in the Orion Nebula

Thu, 11 Jan 18 00:16:30 -0800

Astronomers using NASA's Hubble Space Telescope have uncovered the largest known population of brown dwarfs sprinkled among newborn stars in the Orion Nebula.



NASA calculated heavy rainfall leading to California mudslides

Thu, 11 Jan 18 00:01:40 -0800

Winter rains falling on recently burned ground triggered deadly mudslides in Santa Barbara County, California on Jan. 9. NASA calculated the amount of rain fall between Jan. 8 and 10, 2018 and calculated the potential for landslides.



Frequent growth events and fast growth rates of fine aerosol particles in Beijing

Thu, 11 Jan 18 00:05:20 -0800

Secondary aerosol formation and rapid increases in aerosol particle sizes are believed to play important roles in haze formation. However, some simple but important questions remain unanswered, such as: How frequently and how fast do fine aerosol particles grow? And what affects their rates of growth?



NASA's IMERG measures Tropical Cyclone Ava's disastrous rainfall

Wed, 10 Jan 18 00:12:00 -0800

Tropical cyclone Ava dropped extremely heavy rainfall over Madagascar as it passed over the eastern side of the island country on Jan. 5 and 6, 2018. NASA calculated how much rainfall occurred using satellite data.



In India, subtle corruption robs villagers of roads

Wed, 10 Jan 18 00:14:40 -0800

Examining a major road-building program in India, researchers at Princeton University and the Paris School of Economics used an innovative technique to show that political corruption increased the chances that roads meant to connect isolated areas to the rest of the country would never be built, even though the government had paid for them.



The complexities of clouds and the seeds that make them

Wed, 10 Jan 18 00:02:40 -0800

In an effort to understand exactly how the micro and macro cloud properties interact with atmospheric particles, a collaborative research team conducted a modeling study analyzing three well-documented weather systems that occurred in March of 2000 over the southern Great Plains in the United States.



AK-launched rockets to study X-rays, create polar mesospheric cloud

Tue, 09 Jan 18 00:07:40 -0800

Between Jan. 15-31, 2018, scientists will launch four rockets to measure X-ray emissions from space and determine how large quantities of water could affect the upper atmosphere and form Polar Mesospheric clouds, or PMCs.



Space fever: Weightlessness increases astronauts' body temperature
Astronauts float weightlessly through space, and the condition of weightlessness is something many would love to experience. However, in addition to producing both physical and psychological stress, a trip into space affects our core body temperature. Researchers from Charité - Universitätsmedizin Berlin have observed that astronauts run hot when exposed to weightlessness, and that, even at rest, their body temperature is approximately 1
