U.S. scientists have developed a new, integrated, ten-year science plan to better understand the details of Earth's carbon cycle and people's role in it. Understanding the carbon cycle is central for mitigating climate change and developing a sustainable future.
Arizona State University researchers have created a new compound crystal material, called erbium chloride silicate, that promises to help produce advances in a range of scientific and technological pursuits.
A research team headed by the Georgia Institute of Technology has developed a computer program that can study larger molecules (more than 200 atoms) faster than any other program in existence, helping in pursuit of creating new pharmaceuticals.
By nestling quantum dots in an insulating egg-crate structure, researchers at the Harvard School of Engineering and Applied Sciences have demonstrated a robust new architecture for quantum-dot light-emitting devices (QD-LEDs).
Rice University chemists have found a way to load more than two million tiny gold particles called nanorods into a single cancer cell. The breakthrough could speed development of cancer treatments that would use nanorods like tiny heating elements to cook tumors from the inside.
Geologists at the Massachusetts Institute of Technology and Harvard University have unearthed rare, flask-shaped microfossils dating back 635 to 715 million years, representing the oldest known ciliates in the fossil record.
University of Miami Rosenstiel School of Marine & Atmospheric Science researchers have climate scientists rethinking a commonly held theory about the ocean's role in the global climate system. The new findings can aid scientists in better understanding and predicting changes in the Pacific climate and its impacts around the globe.
University of California, Berkeley, scientists have shown that ionized plasmas like those in neon lights and plasma TVs not only can sterilize water, but make it antimicrobial—able to kill bacteria—for as long as a week after treatment.
Researchers from North Carolina State University are developing a 3D central processing unit (CPU) with the goal of boosting energy efficiency by 15 to 25%. The work is being done under a $1.5 million grant from the Intel Corporation.
To improve the electronic devices that keep our world organized, scientists are on the hunt for new semiconductor materials. One answer could lie with an unusual form of electrical conductivity that takes place at the junction of two oxides. However, a group of scientists were recently surprised to find the interface of two complex oxides—the polar lanthanum chromium oxide, and the nonpolar strontium titanium oxide—did not conduct electricity.
Purdue University scientists have developed a method for stacking synthetic DNA and carbon nanotubes onto a biosensor electrode, a development that may lead to more accurate measurements for research related to diabetes and other diseases.
For decades, scientists have dreamed of building computer systems that could replicate the human brain's talent for learning new tasks. Massachusetts Institute of Technology researchers have now taken a major step toward that goal by designing a computer chip that mimics how the brain's neurons adapt in response to new information.
An analysis of the remains of ancient midges—tiny non-biting insects closely related to mosquitoes—opens a new window on the past with a detailed view of the surprising regional variability that accompanied climate warming during the early Holocene epoch, 10,000 to 5,500 years ago.
Sonar and ultrasound, which use sound as a navigational device to paint accurate pictures of an environment, are the basis of countless technologies, including medical ultrasound machines and submarine navigation systems. But when it comes to more accurate sonar and ultrasound, animals' "biosonar" capabilities still have the human race beat. Until now.
In nature, the strength of mother-of-pearl is a key to survival for some shellfish. Now a team led by Xiaodong Li, an engineering professor at the University of South Carolina, has posited an explanation for the unusual resilience that this important defensive shield shows in the face of predatory attacks.
The company behind a pioneering stem cell bandage, believed to be the world's first adult and autologous (patient's own) stem cell treatment designed to heal torn meniscal cartilage, can now take the technology to human clinical trials thanks to an investment from one of the U.K.'s most successful entrepreneurs.
The University of Illinois says Seattle-based Cray Inc. will take over construction of the stalled $300 million Blue Waters supercomputer project, three months after IBM pulled out citing cost and technical concerns.
Scientists have demonstrated that a superconducting detector called a transition edge sensor (TES) is capable of counting the number of as many as 1,000 photons in a single pulse of light with an accuracy limited mainly by the quantum noise of the laser source.
Increases in air pollution and other particulate matter in the atmosphere can strongly affect cloud development in ways that reduce precipitation in dry regions or seasons, while increasing rain, snowfall, and the intensity of severe storms in wet regions or seasons, says a new study by a University of Maryland-led team of researchers.
When a soldier in good mental health becomes homicidal or a government employee abuses access privileges to share classified information, we often wonder why no one saw it coming. With support from the Defense Advanced Research Projects Agency (DARPA) and the Army Research Office, researchers at the Georgia Institute of Technology are collaborating with scientists from four other organizations to develop new approaches for identifying these "insider threats" before an incident occurs.
Always hydrogen-bonded to other molecules of water or polar compounds, water has never been studied as a single molecule because researchers never been able to isolate it. Two scientists in Japan have recently achieved this for the first time, using organic reactions to push one water molecule into a C60 fullerene cage.
Researchers funded by the National Institutes of Health have developed a flexible brain implant that could one day be used to treat epileptic seizures. In animal studies, the researchers used the device—a type of electrode array that conforms to the brain's surface—to take an unprecedented look at the brain activity underlying seizures.
Dye-sensitized Grätzel solar cells have just set a new efficiency benchmark. By changing the composition and color of the cells, an EPFL team has increased their efficiency to more than 12%.
For the past 100 years, the Haber-Bosch process has been used to convert atmospheric nitrogen into ammonia, which is essential in the manufacture of fertilizer. Despite the longstanding reliability of the process, scientists have had little understanding of how it actually works. Until now.
Researchers studying how biodiesel can be generated using E. coli as a catalyst have determined the bacteria have what it takes to produce high volumes of the fuel. Now they need to figure out how to tweak its cellular controls in order to kick it into high gear.
