For more than a century and a half, researchers interested in invasive species have looked to Charles Darwin and what has come to be called his "naturalization conundrum."
A nanorobot is a popular term for molecules with a unique property that enables them to be programmed to carry out a specific task. In collaboration with colleagues in Italy and the USA, researchers at Aarhus University have now taken a major step towards building the first nanorobot of DNA molecules that can encapsulate and release active biomolecules.
With the help of a new method called "dual-electrode photoelectrochemistry," University of Oregon scientists have provided new insight into how solar water-splitting cells work. An important and overlooked parameter, they report, is the ion-permeability of electrocatalysts used in water-splitting devices.
Hidden underneath the hilly grasslands studded with ocotillos and mesquite trees in southeastern Arizona lies a world shrouded in perpetual darkness: Kartchner Caverns, a limestone cave system renowned for its untouched cave formations, sculpted over millennia by groundwater dissolving the bedrock and carving out underground rooms, and passages that attract tourists from all over the world.
– A new study reveals how pollution causes thunderstorms to leave behind larger, deeper, longer lasting clouds. Appearing in the Proceedings of the National Academy of Sciences November 26, the results solve a long-standing debate and reveal how pollution plays into climate warming. The work can also provide a gauge for the accuracy of weather and climate models.
Observations of a black hole powering an energetic X-ray source in a galaxy some 22 million light-years away could change our thinking about how some black holes consume matter.
Located only about 160 000 light-years from us (eso1311) in the constellation of Dorado (The Swordfish), the Large Magellanic Cloud is one of our closest galactic neighbours.
Shortly after China’s Chang’e-3 spacecraft departed Earth to land on the Moon, ESA’s network of tracking stations swung into action, providing crucial support for the vessel’s five-day lunar cruise.
Scientists have recorded and identified one of the most prominent sounds of a warming planet: the sizzle of glacier ice as it melts into the sea. The noise, caused by trapped air bubbles squirting out of the disappearing ice, could provide clues to the rate of glacier melt and help researchers better monitor the fast-changing polar environments.
Instead of making biofuel from newly planted crops like Arundo donax – one of the main feedstocks at a big new cellulosic ethanol facility in Italy, and a plant that some environmentalists fear – why not harvest the invasive species that are already causing problems?
Toyota, from the floor of the Los Angeles Auto Show, has unveiled the third generation of itsHighlander Hybrid. It has bumped up in starting price for the 2014 model from the previous year significantly, reflecting what seems to be the new design and technology touches going into this latest iteration.
Spanish researchers, including scientists from the University of Valencia, have developed small synthetic molecules capable of joining to the genetic material of the AIDS virus and blocking its replication.
A top genetics expert claims that he has found evidence that modern humans were caused by pigs and chimps mating.
An international team of researchers has found playing violent video games not only increases aggression but can also cause players to cheat and eat more chocolate.
The outfit which brought the psychological genius Wilhelm Reich to an early grave, is now gunning for Anne Wojcicki, Sergey Brin's cuckquean.
Creating a computer program to find relationships in networks, such as Google Plus and Facebook, may help users more easily set up and maintain privacy settings, according to researchers.
A $500 "nano-camera" that can operate at the speed of light has been developed by researchers in the MIT Media Lab. The three-dimensional camera, which was presented last week at Siggraph Asia in Hong Kong, could be used in medical imaging and collision-avoidance detectors for cars, and to improve the accuracy of motion tracking and gesture-recognition devices used in interactive gaming.
Scientists should take the conservative approach when searching for habitable zones where life-sustaining planets might exist, according to James Kasting, Evan Pugh Professor of Geosciences at Penn State, including when building Terrestrial Planet Finders.
The Galaxy has been making stars for the last 8 billion years. What’s kept it going all that time? When old stars die, some of their gas goes back into the galactic “soup” for star making. But in the long run a lot of it gets locked up in long-lived dwarf stars.
Black holes can be petite, with masses only about 10 times that of our sun -- or monstrous, boasting the equivalent in mass up to 10 billion suns. Do black holes also come in size medium? NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, is busy scrutinizing a class of black holes that may fall into the proposed medium-sized category.
