Temperature Variability Across the World Alters the Ecological Impacts of Seasons

Study Reveals Climate Change Alters the Ecological Impacts of Seasons

New research from the Max Planck Institute for Developmental Biology and the University of Wyoming details how changes in temperature variability across the globe are altering the environment. If more of the world’s climate becomes like that in tropical zones, it could potentially affect crops, insects, malaria transmission, and even confuse migration patterns of birds […]

Noninvasive Arterial Spin Labeling MRI Detects Evidence of Cognitive Decline Before Symptoms Appear

New MRI Technique Detects Evidence of Cognitive Decline

A new study shows that a noninvasive arterial spin labeling MRI can detect signs of cognitive decline in the brain even before symptoms appear, finding that patients who showed reduced brain perfusion at their initial exams exhibited cognitive decline at follow-up 18 months later. Oak Brook, Illinois — A magnetic resonance imaging (MRI) technique can […]

Killer Whales Engage in Cross-Species Vocal Learning

Killer Whales Demonstrate Cross-Species Vocal Learning

A newly published study reveals that killer whales (Orcinus orca) can engage in cross-species vocal learning, revealing that they shifted the types of sounds they made to more closely match the bottlenose dolphins they cross-socialized with. Washington, D.C. — From barks to gobbles, the sounds that most animals use to communicate are innate, not learned. […]

Rosetta Spacecraft Reveals Hidden Crater on Asteroid Lutetia

Asteroid Lutetia

Images by ESA’s Rosetta spacecraft reveal the existence of a large impact crater on the unseen side of the Lutetia asteroid. Rosetta flew past Lutetia at a distance of 3168 km in July 2010, en route to its 2014 rendezvous with its target comet. The spacecraft took images of the 100 km-wide asteroid for about […]

Satellite Records Show Antarctic Sea Ice Reaches New Record Maximum

Antarctic Sea Ice Reaches New Maximum

Long-term satellite records show that the five-day average of Antarctic sea ice extent reached a new record high this year. This year, Antarctic sea ice reached a record maximum extent while the Arctic reached a minimum extent in the ten lowest since satellite records began. Why are these trends going in opposite directions? Image Credit: […]

Physicists Discover Negative Photoconductivity in Monolayer MoS2

New Mechanism of Photoconduction Could Lead to Next Generation Excitonic Devices

Physicists at MIT have discovered that shining light on a single layer of molybdenum disulfide (MoS2) can make the material less conductive. It’s a well-known phenomenon in electronics: Shining light on a semiconductor, such as the silicon used in computer chips and solar cells, will make it more conductive. But now researchers have discovered that […]

Researchers Examine Emerging Market for Used Electric Vehicle Batteries

Report Examines Emerging Market for Used Electric Vehicle Batteries

A new report from UCLA and UC Berkeley shows that used electric car batteries could help California achieve its renewable energy, greenhouse gas reduction and energy storage goals more efficiently — and could lower the cost of owning an electric car. As California searches for cheap energy storage options, a new report by the Climate […]

Astronomers Use Telescopes to Track Laws of Nature 10 Billion Years Ago

Three Telescopes Track Laws of Nature 10 Billion Years Ago

Using the three most powerful optical telescopes in the world, astronomers from Swinburne University have focused on a single point in the sky to test one of Nature’s fundamental laws. An international team, led by researchers from Swinburne University of Technology, observed a quasar – the extremely bright surroundings of a supermassive black hole – […]

GIANT Research Shows Large Number of Genes Linked to Human Height

Research Shows Giant Number of Genes Linked to Human Height

A newly published study from the international Genetic Investigation of Anthropometric Traits (GIANT) Consortium gives scientists a better look at the biology of height and offers a model for investigating traits and diseases caused by many common gene changes acting together. Cambridge, Massachusetts — The largest genome-wide association study (GWAS) to date, involving more than […]

New Research Reveals That Trade is a Major Driver of Biodiversity

Lizard Study Shows Trade is a Force in Biodiversity

A newly published study shows that trade is one of the major drivers of biodiversity among lizard species in the Caribbean islands, finding that the amount of trade an island receives can explain to a large extent the number of invasive species on an island. It may be a cliché to say it, but the […]

Study Shows Coffee Drinking Habits Shaped by DNA Variations

Research Reveals Coffee Drinking Habits Shaped by Genetic Variations

A study by the international Coffee and Caffeine Genetics Consortium looked at DNA samples and data sets from the coffee-drinking habits of 120,000 people of European and African-American ancestry, providing insight on why caffeine affects people differently, and how these effects influence coffee-drinking behavior. An international research team has found six new genes underlying our […]

Nanoparticles Allows Physicists to Select the Direction of Light

Nanoparticles Break the Symmetry of Light

Using an unusual kind of coupling between spin and the direction of propagation, physicists from the Vienna University of Technology are able to select the direction that nanoparticles can emit light into ultra-thin glass fibers. How can a beam of light tell the difference between left and right? At the Vienna University of Technology (TU […]
