Researchers at The Univ. of Manchester have made a significant breakthrough in the development of synthetic pathways that will enable renewable biosynthesis of the gas propane. This research is part of a program of work aimed at developing the next generation of biofuels.
Carbon capture will play a central role in helping the nations of the world manage and reduce their greenhouse gas emissions. Many materials are being tested for the purpose of capturing carbon dioxide. But now researchers led by the Norwegian Univ. of Science and Technology have found that ordinary clay can work just as effectively as more advanced materials.
The discovery of antibiotics produced by soil fungi and bacteria gave the world life-saving medicine. But new antimicrobials from this resource have become scarce as the threat of drug resistance grows. Now, scientists have started mining lakes and rivers for potential pathogen-fighters, and they’ve found one from Lake Michigan that is effective against drug-resistant tuberculosis.
Life may seem precarious for the sea sponge known as Venus’ flower basket. Tiny, hair-like appendages made essentially of glass are all that hold the creatures to their seafloor homes. But fear not for these creatures of the deep. Those tiny lifelines, called basalia spicules, are fine-tuned for strength, according to new research led by Brown Univ. engineers.
The first-ever perfume delivery system to ensure the more a person sweats, the better they will smell, has been developed by scientists at Queen’s Univ. Belfast. The researchers have developed a unique new perfume delivery system which releases more of its aroma when it comes into contact with moisture, meaning a person smells nicer when their sweat levels increase.
Analyzing people’s keystrokes as they type on a computer keyboard can reveal a great deal of information about the state of their motor function, according to a new study. In the study, the researchers found that their algorithm for analyzing keystrokes could distinguish between typing done in the middle of the night, when sleep deprivation impairs motor skills, and typing performed when fully rested.
Many studies show that video gamers perform better than non-gamers on certain visual tasks, like managing distractors and identifying targets, but a small new Brown Univ. study provides gamers with some cognitive bonus points. The study results suggest that gaming not only improves their visual skill but also may improve their learning ability for those skills.
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.
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.
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.
New research has identified some of the processes by which molecules associated with neurological diseases can disrupt the biological clock, interfere with sleep and activity patterns and set the stage for a spiral of health concerns that can include a decreased lifespan and Alzheimer’s disease.
How many researchers does it take to change a light bulb? And how many lives could they save by changing it? The answer to both questions is larger than you might expect. In the developing world, light bulbs might as well be insect magnets. The light they emit, particularly the blue wavelengths of LED lights, is attractive to a range of insects, drawing them out from the night and straight to people's homes.
In a new paper, a team of Yale Univ. researchers assesses the “criticality” of all 62 metals on the Periodic Table of Elements, providing key insights into which materials might become more difficult to find in the coming decades, which ones will exact the highest environmental costs and which ones simply cannot be replaced as components of vital technologies.
Scientists have observed the point at which classical and quantum behavior converge. Using a fiber-based nonlinear process, the researchers were able to observe how, and under what conditions, "classical" physical behavior emerges from the quantum world.
Saccharin, the artificial sweetener that is the main ingredient in Sweet 'N Low, Sweet Twin and Necta, could do far more than just keep our waistlines trim. According to new research, this popular sugar substitute could potentially lead to the development of drugs capable of combating aggressive, difficult-to-treat cancers with fewer side effects.
Poop could be a goldmine, literally. Surprisingly, treated solid waste contains gold, silver and other metals, as well as rare elements such as palladium and vanadium that are used in electronics and alloys. Now researchers are looking at identifying the metals that are getting flushed and how they can be recovered. This could decrease the need for mining and reduce the unwanted release of metals into the environment.
Lava tubes large enough to house cities could be structurally stable on the moon, according to a theoretical study. The volcanic features are an important target for future human space exploration because they could provide shelter from cosmic radiation, meteorite impacts and temperature extremes.
Could our reaction to an image of an overweight or obese person affect how we perceive odor? A trio of researchers, including two from the Univ. of California, Los Angeles, says yes. The researchers discovered that visual cues associated with overweight or obese people can influence one’s sense of smell, and that the perceiver’s body mass index matters, too.
Green tea’s popularity has grown quickly in recent years. Its fans can drink it, enjoy its flavor in their ice cream and slather it on their skin with lotions infused with it. Now, the tea could have a new, unexpected role—to improve the image quality of MRIs. Scientists report in ACS Applied Materials & Interfaces that they successfully used compounds from green tea to help image cancer tumors in mice.
More than a million young stars are forming in a hot, dusty cloud of molecular gases in a tiny galaxy near our own, an international team of astronomers has discovered. The star cluster is buried within a supernebula in a dwarf galaxy known as NGC 5253, in the constellation Centaurus. The cluster has one billion times the luminosity of our sun, but is invisible in ordinary light, hidden by its own hot gases.
Plastic products advertised as biodegradable have recently emerged, but they sound almost too good to be true. Scientists have now found out that, at least for now, consumers have good reason to doubt these claims. In a new study appearing in Environmental Science & Technology, plastics designed to degrade didn’t break down any faster than their more conventional counterparts.
Researchers at Sandia National Laboratories’ Z machine have helped untangle a long-standing mystery of astrophysics: Why iron is found spattered throughout Earth’s mantle, the roughly 2,000-mile thick region between Earth’s core and its crust.
A team of researchers in the U.K. has found a way to redesign an artificial connection between an artery and vein, known as an Arterio-Venous Fistulae, which surgeons form in the arms of people with end-stage renal disease so that those patients can receive routine dialysis, filtering their blood and keeping them alive after their kidneys fail.
The velvet worm is a slow-moving, unassuming creature. With its soft body, probing antennae and stubby legs, it looks like a slug on stilts as it creeps along damp logs in tropical climates. But it has a secret weapon. In the dark of night, when an unsuspecting cricket or termite crosses its path, the worm unleashes an instantaneous torrent of slime.
There are only five bodies in our solar system that are known to bear rings. The most obvious is the planet Saturn; to a lesser extent, rings of gas and dust also encircle Jupiter, Uranus and Neptune. The fifth member of this haloed group is Chariklo, one of a class of minor planets called centaurs: small, rocky bodies that possess qualities of both asteroids and comets.
