Scientists at the University of York have conducted new research into measuring how commonly-prescribed pharmaceuticals behave in the guts of starlings.
In a study led by Tom Bean, Professor Alistair Boxall and Dr Kathryn Arnold, from the University's Environment Department, researchers developed an in-vitro model (a laboratory-based system that avoids use of animal tests) to simulate the digestive system of a starling, recreating gastro-intestinal conditions that appear in real birds.
RCW 106 is a sprawling cloud of gas and dust located about 12 000 light-years away in the southern constellation of Norma (The Carpenter's Square). The region gets its name from being the 106th entry in a catalogue of H II regions in the southern Milky Way [1]. H II regions like RCW 106 are clouds of hydrogen gas that are being ionised by the intense starlight of scorching-hot, young stars, causing them to glow and display weird and wonderful shapes.
A new NASA study finds that the recent drought that began in 1998 in the eastern Mediterranean Levant region, which comprises Cyprus, Israel, Jordan, Lebanon, Palestine, Syria, and Turkey, is likely the worst drought of the past nine centuries.
Scientists reconstructed the Mediterranean's drought history by studying tree rings as part of an effort to understand the region's climate and what shifts water to or from the area. Thin rings indicate dry years while thick rings show years when water was plentiful.
Spending nearly a year in space, 249 miles from Earth, could be a lonely prospect, but an office at NASA's Goddard Space Flight Center in Greenbelt, Maryland, made sure astronaut Scott Kelly could reach home for the entire 340-day duration of his mission. Not only could Kelly communicate with mission control in Houston, but Goddard's Network Integration Center connected him with reporters and even family.
MANHATTAN, KANSAS -- Climate change may have a new way of getting under your skin.
Researchers in the College of Veterinary Medicine at Kansas State University have validated a model showing growth in Kansas for the habitat of the troublesome lone star tick. Previously thought only to live in the eastern third of the state, computational modeling and live specimens have revealed the existence of these ticks as far west as Colby, which is only 55 miles from the Colorado state line.
DURHAM, N.C. -- A Duke theorist says there's a very good reason why objects in the universe come in a wide variety of sizes, from the largest stars to the smallest dust motes -- and it has a lot to do with how paint cracks when it dries.
In a paper published March 1 in the Journal of Applied Physics, Adrian Bejan, the J.A. Jones Professor of Mechanical Engineering at Duke University, explains how the need to release internal tension shaped the universe as we see it.
Many technologies used in human societies are beyond the inventive capacities of individuals. Instead, technologies result from a cumulative process where innovations are gradually added across many generations--think from the wheel to modern cars or from early planes to space shuttles.
The chair of ophthalmology at the University of Michigan examined a recent report investigating the value of vision screening for older adults with no symptoms.
Paul Lee's editorial, published online today in JAMA, explains the U.S. Preventive Services Task Force report, also published today in JAMA.
The USPSTF work states that current evidence doesn't allow for assessment of clear recommendation supporting the use of visual acuity in screening those 65 and older who have no symptoms and are not already under eye care.
Aflibercept (trade name: Eylea) has been approved since October 2015 for adults with impaired vision due to myopic choroidal neovascularisation.
A team of researchers from Japan's Tohoku University has developed a new method for the pretreatment of organic material, or "biomass", which could lead to more efficient production of biofuels and biochemicals.
Pretreating biomass improves the formation of sugars that are then used to develop biofuels and biochemicals. But current pretreatment processes leave much to be desired.
Nagoya, Japan - Coronal mass ejections (CMEs) are massive expulsions of magnetic flux into space from the solar corona, the ionized atmosphere surrounding the sun. Magnetic storms arising from CMEs pose radiation hazards that can damage satellites and that can negatively impact communications systems and electricity on Earth. Accurate predictions of such events are invaluable in space weather forecasting.
Research from the University of Washington-based Virtual Planetary Laboratory published Feb. 26 in Astrophysical Journal Letters will help astronomers better identify -- and thus rule out -- "false positives" in the search for life beyond Earth.
HAMILTON, March 1, 2016 - As scientists step up their search for other life in the universe, two astrophysicists are proposing a way to make sure we don't miss the signal if extraterrestrial observers try to contact us first.
René Heller and Ralph Pudritz say the best chance for us finding a signal from beyond is to presume that extraterrestrial observers are using the same methods to search for us that we are using to search for life beyond Earth.
NASA scientists are closer to solving the mystery of how Mars' moon Phobos formed.
In late November and early December 2015, NASA's Mars Atmosphere and Volatile Evolution (MAVEN) mission made a series of close approaches to the Martian moon Phobos, collecting data from within 300 miles (500 kilometers) of the moon.
Among the data returned were spectral images of Phobos in the ultraviolet. The images will allow MAVEN scientists to better assess the composition of this enigmatic object, whose origin is unknown.
Brooklyn, NY - A study led by SUNY Downstate Medical Center has found increased risk of obesity among Filipino immigrants living in the New York City metropolitan area. The findings were published in the January/March issue of the journal, Family & Community Health.
