A new Georgia Institute of Technology study shows that an intense workout of as little as 20 min can enhance episodic memory, also known as long-term memory for previous events, by about 10% in healthy young adults. The research isn’t the first to find that exercise can improve memory. But the study took a few new approaches, including testing memory after just single period of exercise.
The most comprehensive assessment conducted by the Ocean Health Index rates the Earth’s oceans at 67 out of 100 in overall health. In addition, for the first time, the report assessed the Antarctic and the 15 ocean regions beyond national jurisdiction (high-seas areas). Together with the 220 exclusive economic zones (EEZs) measured in 2012 and 2013, the index now measures all of the oceans on planet Earth.
The National Institutes of Health this week announced its first research grants through President Barack Obama’s BRAIN Initiative, including three awards to the Univ. of California, Berkeley, totaling nearly $7.2 million over three years. The projects are among 58 funded in this initial wave of NIH grants, involving 100 researchers and a total of $46 million in fiscal year 2014 dollars alone.
More than one hundred and fifty years ago, Charles Darwin hypothesized that species could cross oceans and other vast distances on vegetation rafts, icebergs, or in the case of plant seeds, in the plumage of birds. Though many were skeptical of Darwin's "jump dispersal" idea and instead supported the idea of the use of land bridges, a new computational method now suggests that Darwin might have been correct.
Drawn relentlessly by their electrical charges, lithium ions in a battery surge from anode to cathode and back again. Yet, no one really understands what goes on at the atomic scale as lithium ion batteries are used and recharged. Using transmission electron microscopy, researchers are now glimpsing what can happen to anodes as lithium ions work their way into them. The “atomic shuffling” these ions perform leads to rapid anode failure.
A Duke Univ. team has found that nanoparticles called single-walled carbon nanotubes accumulate quickly in the bottom sediments of an experimental wetland setting, an action they say could indirectly damage the aquatic food chain. According to the research, the risk to humans ingesting the particles through drinking water is slight, but aquatic food chains might be harmed by molecules "piggybacking" on the carbon nanoparticles.
Cancer vaccines have recently emerged as a promising approach for killing tumor cells before they spread. But so far, most clinical candidates haven’t worked that well. Now, scientists have developed a new way to deliver vaccines that successfully stifled tumor growth when tested in laboratory mice. And the key is in the vaccine’s unique stealthy nanoparticles.
A collaboration has been announced between Agilent Technologies and the Univ. of Toronto’s Donnelly Centre for Cellular and Biomolecular Research to produce a comprehensive metabolomics multiple-reaction monitoring library and methodology, using Agilent’s Infinity 1290 UHPLC, 6460 triple quadrupole mass spectrometry system, and MassHunter Software. The goal is to accelerate quantification of hundreds of metabolically important compounds.
Ice contains many atoms and molecules trapped inside its structure. A team of Univ. of Chicago and Loyola Univ. researchers has discovered a new mechanism they call "stable energetic embedding" of atoms and molecules within ice. This mechanism explains how some molecules, such as CF4, or "carbon tetrafluoride", interact with and become embedded beneath ice surfaces.
Despite being outlawed in 2012 in the U.S., the synthetic drugs known as "bath salts" are still readily available in some retail shops, on the Internet and on the streets. To help law enforcement, scientists are developing low-cost, disposable, mercury-free electrodes that could be the basis for the first portable, on-site testing device for identifying the drugs.
Princeton Instruments has announced the immediate availability of the ProEM-HS line of high-speed EMCCD cameras with patented eXcelon3 technology (X3) for low-light imaging and spectroscopy applications. This advanced back-illuminated EMCCD technology offers combination of high quantum efficiency (>95% QE), best fringe suppression in the near infrared and single-photon sensitivity.
GP:50 Corporation Ltd. has introduced its Model 188/288/388 miniature flush diaphragm pressure transducer series. The unique flush diaphragm design of the GP:50 Model 188/288/388 now makes possible accurate pressure measurements of high-viscosity fluids, even within high shock and vibration environments, without port plugging and clogging.
It was, retired Japanese railway engineer Fumihiro Araki recalls, "like flying in the sky." Zipping cross-country in a super-high-speed train has become commonplace in many countries these days, but it was unheard of when Japan launched its bullet train between Tokyo and Osaka 50 years ago Wednesday.
Thermal considerations are rapidly becoming one of the most serious design constraints in microelectronics, especially on submicron scale lengths. A study by researchers from the Univ. of Illinois at Urbana-Champaign has shown that standard thermal models will lead to the wrong answer in a 3-D heat-transfer problem if the dimensions of the heating element are on the order of one micron or smaller.
Inspired by a desire to help wounded soldiers, an international team has created a paint-on, see-through, “smart” bandage that glows to indicate a wound’s tissue oxygenation concentration. Because oxygen plays a critical role in healing, mapping these levels in severe wounds and burns can help to greatly improve the success of surgeries to restore limbs and physical functions.
Brine shrimp, which are sold as pets known as sea-monkeys, are tiny—only about half an inch long each. With about 10 small leaf-like fins that flap about, they look as if they could hardly make waves. But get billions of similarly tiny organisms together and they can move oceans.
Researchers in the Netherlands can now, for the first time, remotely control a miniature light source at timescales of 200 trillionths of a second. Physicists have developed a way of remotely controlling the nanoscale light sources at an extremely short timescale. These light sources are needed to be able to transmit quantum information.
Only a minority of suspicious mammograms actually leads to a cancer diagnosis, which results in lots of needless worry and spent time for women and their families. Ultrasound elastography could be an excellent screening tool but it requires a lot of skill and interpretation. In an effort to improve results, researchers in Michigan have developed a virtual “breast”, allowing medical professionals to practice in the laboratory.
The 52nd annual R&D 100 Awards event will present a series of panel discussions featuring today’s top technological minds revealing their secrets for innovation. Draw inspiration from these leading experts as they discuss technology-driven strategies for transforming your ideas into excellence.
The discovery of a gene mutation that causes a rare premature aging disease could lead to the development of drugs that block the rapid, unstoppable cell division that makes cancer so deadly. Scientists at the Univ. of Michigan recently discovered a protein mutation that causes the devastating disease dyskeratosis congenita, in which precious hematopoietic stem cells can't regenerate and make new blood.
Graphene quantum dots created at Rice Univ. grab onto graphene platelets like barnacles attach themselves to the hull of a boat. But these dots enhance the properties of the mothership, making them better than platinum catalysts for certain reactions within fuel cells.
Given a choice, most patients would prefer to take a drug orally instead of getting an injection. Unfortunately, many drugs, can’t be given as a pill because they get broken down in the stomach before they can be absorbed. To help overcome that obstacle, researchers have devised a novel drug capsule coated with tiny needles that can inject drugs directly into the lining of the stomach after swallowed.
Federal health officials on Tuesday confirmed the first case of Ebola diagnosed in the U.S., a patient who recently traveled from Liberia to Dallas and a sign of the far-reaching impact of the out-of-control epidemic in West Africa. The unidentified patient was critically ill and has been in isolation at Texas Health Presbyterian Hospital since Sunday, officials said.
