Researchers Develop New Temperature Switchable Membrane

Researchers from the University of Connecticut and Yale University have developed a new membrane with highly aligned nanoscale pores that open and close in response to temperature; this highly porous, valve-like material has many potential filtration applications, including water purification and molecular separation. The membrane was created from a block copolymer that self-assembles into alternating […]

Semiaquatic Dinosaur Spinosaurus Aegyptiacus

An international team of scientists has unveiled the first truly semiaquatic dinosaur, Spinosaurus aegyptiacus. New fossils of the massive Cretaceous-era predator reveal it adapted to life in the water some 95 million years ago, providing the most compelling evidence to date of a dinosaur able to live and hunt in an aquatic environment. The fossils […]

Scientists Create a De-Icing Film for Glass

Researchers from Rice University have developed a transparent graphene nanoribbon film that can be used to prevent ice and fog buildup on glass and plastic, as well as radar domes and antennas. Rice University scientists who created a de-icing film for radar domes have now refined the technology to work as a transparent coating for […]

New Materials Have the Ability to Quickly Change Colors and Textures

A team of engineers has developed a new synthetic material that can change its fluorescence and texture in response to a change in voltage applied to it. Cephalopods, which include octopuses, squid, and cuttlefish, are among nature’s most skillful camouflage artists, able to change both the color and texture of their skin within seconds to […]

Jellyfish Flame on the International Space Station

A new four minute ScienceCast video looks at the lifelike behavior and underlying physics of flames on the International Space Station. ScienceCasts: Jellyfish Flame on the International Space Station Astronauts onboard the International Space Station report seeing flames that behave like jellyfish. Video of the microgravity phenomenon is a must-see. Fire is inanimate, yet anyone […]

Interface Region Imaging Spectrograph Satellite Observes Major Solar Flare

NASA’s Interface Region Imaging Spectrograph satellite observed its largest solar flare since launching in 2013 – an X1.6 class flare. On September 10, 2014, NASA’s IRIS satellite observed an X1.6 class flare based on the high intensity of X-ray radiation. “X-class” events are the most powerful, and this one comes on the heels of another […]

Researchers Give Guideline for Future Alien Life Search

Using an altitude-dependent photochemical model with the enhanced lower boundary conditions necessary to carefully explore abiotic oxygen and ozone production on lifeless planets with a wide variety of volcanic gas fluxes and stellar energy distributions, scientists at NASA have developed new guidelines for the search for life on other planets. Astronomers searching the atmospheres of […]

New Research Documents the Prevalence of Hadrosaur Skin

A new study from Yale University details the prevalence of hadrosaur skin among all known dinosaur skin fossils, revealing that hadrosaur skin is 31 times more likely to be preserved. In life, Tyrannosaurus rex usually got the best of the less fearsome duck-billed dinosaurs, or hadrosaurs: T. rex ate them. But in death, the plant-eating […]

Brain Structure Could Predict Risky Behavior

New research shows that brain structure may predict risky behavior, revealing that those with a larger volume in a particular part of the parietal cortex were willing to take more risks than those with less volume in this part of the brain. Some people avoid risks at all costs, while others will put their wealth, […]

Movable Cytoskeleton Membrane Fabricated for First Time

Biophysicists detail how they engineered synthetic materials that mimic the remarkable complexity of living organisms, successfully implementing a minimalistic model of the cell that can change its shape and move on its own. Cells are complex objects with a sophisticated metabolic system. Their evolutionary ancestors, the primordial cells, were merely composed of a membrane and […]

Changing Diets is Vital to Reducing Climate Change

A newly published study from University of Cambridge shows that food production is a main driver of biodiversity loss and a large contributor to climate change and pollution. A new study, published today in Nature Climate Change, suggests that – if current trends continue – food production alone will reach, if not exceed, the global […]

Scientists Discover New Supermassive Dinosaur Species

A team of scientists at Drexel University have unveiled a new supermassive dinosaur species discovered between 2005 and 2009. Weighing in at nearly 65 tons and measuring 85 feet long, Dreadnoughtus schrani is the largest land animal ever found of calculable mass and one of the most complete skeletons ever found for a dinosaur in […]
