A surprising phenomenon has been found in metal nanoparticles: they appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal configuration.
Highlighting unexpected similarities between what animals do and what people are trying to do is a new strategy researchers are using to hopefully increase public awareness about animals and encourage conservation. They’ve created an iPhone app based on biologically inspired design, highlighting two dozen species that have helped engineers solve problems or invent new solutions.
Using a first-of-its-kind, high-resolution numerical model to describe ocean circulation during the last ice age about 21,000 year ago, an oceanographer has shown that icebergs and melt water from the North American ice sheet would have regularly reached South Carolina and even southern Florida.
It is well known that patients should avoid eating and drinking before surgery to help prevent complications while under anesthesia. Although chewing gum significantly increases the volume of liquids in the stomach, it is safe to administer sedatives or anesthesia to patients who have chewed gum while fasting before surgery, reports a new study.
Scientists have discovered that a common insulating material behaves as a perfect spintronic conductor because it is not affected by background electron charge.
The editors of Laboratory Equipment want you to start your week with a smile on your face. So, here’s a science joke you might like. Q: What do you call a tooth in a glass of water?
Scientists and engineers have developed a new surface coating for medical devices using materials already approved by the FDA. The coating repelled blood from more than 20 medically relevant substrates the team tested– some plastic, glass or metal– and also suppressed biofilm formation.
A single application of a common anesthetic procedure could be the answer to alleviating anxiety, depression and psychological pain in those suffering from chronic, extreme post-traumatic stress disorder.
Exercise is one of the best ways to protect against dementia in later life and the earlier you start, the greater the effect, research suggests. Hobbies that keep the brain active, such as playing an instrument, going to concerts or joining a book club, can also be very helpful as long as it is an activity a person enjoys.
Electronic devices that dissolve completely in water, leaving behind only harmless end products, are part of a rapidly emerging class of technology. A new generation of transient electronic devices function in water but dissolve when their function is no longer needed.
The nation's largest flight attendants union is arguing that aviation officials flew in the face of a federal law last year when they cleared passengers to use small electronic devices during take-offs and landings.
A surprising hot spot of the potent global warming gas methane hovers over part of the southwestern U.S., according to satellite data. That result hints that the EPA and other agencies considerably underestimate leaks of the natural gas.
A web-based system that allows preschools and child care centers to report illnesses to local public health departments could improve the detection of disease outbreaks and allow resources to be mobilized more quickly.
Researchers have unveiled a new method to form 3-D metal nanoparticles in prescribed shapes and dimensions using DNA as a construction mold. The ability to mold inorganic nanoparticles out of materials such as gold and silver is a significant breakthrough that has the potential to advance laser technology, microscopy, solar cells, electronics, environmental testing, disease detection and more.
Researchers have developed an automated imaging technique for measuring and analyzing the root systems of mature plants. The technique uses advanced computer technology to analyze photographs taken of root systems in the field. The imaging and software are designed to give scientists the statistical information they need to evaluate crop improvement efforts.
