Taking our understanding of quantum matter to new levels, scientists at Los Alamos National Laboratory are exposing high-temperature superconductors to very high magnetic fields, changing the temperature at which the materials become perfectly conducting and revealing unique properties of these substances.
Caltech scientists, inspired by a chemical process found in leaves, have developed an...

Dielectric elastomers are novel materials for making actuators or motors with soft and lightweight properties that can undergo large active deformations with high-energy conversion efficiencies. This has made dielectric elastomers popular for creating devices such as robotic hands, soft robots, tunable lenses and pneumatic valves, and possibly flapping robotic wings.
Scientists from ETH Zurich have developed a thermometer that is at least 100 times more sensitive than previous temperature sensors. It consists of a bio-synthetic hybrid material of tobacco cells and nanotubes. Humans have been inspired by nature since the beginning of time. We mimic nature to develop new technologies, with examples ranging from machinery to pharmaceuticals to new materials.
Researchers at the National Univ. of Singapore have discovered that the inherent handedness of molecular structures directs the behavior of individual cells and confers them the ability to sense the difference between left and right. This is a significant step forward in the understanding of cellular biology.
An international research team, led by a Virginia Tech geoscientist, has revealed information about how continents were generated on Earth more than 2.5 billion years ago, and how those processes have continued within the last 70 million years to profoundly affect the planet's life and climate.
Memory and as well as connections between brain cells were restored in mice with a model of Alzheimer’s given an experimental cancer drug, Yale School of Medicine researchers reported in the Annals of Neurology. The drug, AZD05030, developed by Astra Zeneca proved disappointing in treating solid tumors but appears to block damage triggered during the formation of amyloid-beta plaques, a hallmark of Alzheimer’s disease.
Scientists have found a way to measure the unseen toll that environmental stress places on living creatures, showing that they can rev up their metabolism to work more than twice as hard as normal to cope with change. Stresses from climate change such as rising temperatures and increasing ocean acidity can move an organism closer and closer to the brink of death without visible signs.
The decades worth of data that has been collected about the billions of neurons in the brain is astounding. To help scientists make sense of this “brain big data,” researchers at Carnegie Mellon Univ. have used data mining to create www.neuroelectro.org, a publicly available Website that acts like Wikipedia, indexing physiological information about neurons.
Speaking in public is the top fear for many people. Now, researchers from the Human-Computer Interaction Group at the Univ. of Rochester have developed an intelligent user interface for “smart glasses” that gives real-time feedback to the speaker on volume modulation and speaking rate, while being minimally distracting.
To understand when and why volcanoes erupt, scientists study the rocks left behind by eruptions past. A method called geobarometry uses the composition of volcanic rocks to estimate the pressure and depth at which molten magma was stored just before it erupted. A research team has tested a new type of geobarometer that is well-suited to study the kind of magma often produced in explosive and destructive volcanic eruptions.
Don't throw away those bouncing batteries. Researchers at Princeton Univ. have found that the common test of bouncing a household battery to learn if it is dead or not is not actually an effective way to check a battery's charge.
Scientists from the Florida campus of The Scripps Research Institute have uncovered the unique mechanism of a powerful natural product with wide-ranging antifungal, antibacterial antimalaria and anticancer effects. The new study sheds light on the natural small molecule known as borrelidin.
In the first study of its kind, scientists at Lawrence Berkeley National Laboratory quantitatively show that electric vehicles (EVs) will meet the daily travel needs of drivers longer than commonly assumed. Many drivers and much prior literature on the retirement of EV batteries have assumed that EV batteries will be retired after the battery has lost 20% of its energy storage or power delivery capability.
An experimental drug rapidly shrinks most tumors in a mouse model of human breast cancer, researchers report in the Proceedings of the National Academy of Sciences. When mice were treated with the experimental drug, BHPI, the tumors immediately stopped growing and began shrinking rapidly.
Sitting in traffic during rush hour is not just frustrating for drivers; it also adds unnecessary greenhouse gas emissions to the atmosphere. Now a study by researchers at Massachusetts Institute of Technology could lead to better ways of programming a city’s stoplights to reduce delays, improve efficiency and reduce emissions.
A vibrational spectroscopic imaging technology that can take images of living cells could represent an advanced medical diagnostic tool for the early detection of cancer and other diseases. High-speed spectroscopic imaging makes it possible to observe the quickly changing metabolic processes inside living cells and to image large areas of tissue, making it possible to scan an entire organ.
