Samsung Electronics Co. has beefed up the camera in its Galaxy S5 smartphone due for April release and added smarter camera software, following Sony and Nokia in their upgrades of handset cameras. The tweaks mean smartphone photos, ubiquitous nowadays because of social media such as Facebook and Twitter, will be closer in quality to images captured by digital single-lens reflex cameras, also known as DSLR.
In recent years, palm oil production has come under fire from environmentalists concerned about the deforestation of land in the tropics to make way for new palm plantations. Now there is a new reason to be concerned about palm oil’s environmental impact, according to researchers at the Univ. of Colorado Boulder.
Immune system defenses against dangerous bacteria in the gut can be breached by turning off a single molecular switch that governs production of the protective mucus lining our intestinal walls, according to a study led by researchers at Yale Univ., the Univ. of British Columbia and the Weizmann Institute of Science.
NASA on Wednesday confirmed a bonanza of 715 newly discovered planets outside our solar system. Scientists using the planet-hunting Kepler telescope pushed the number of planets discovered in the galaxy to about 1,700. Twenty years ago, astronomers had not found any planets circling stars other than the ones revolving around our sun.
Shortly following the 9/11 terror attack in 2001, letters containing anthrax spores were mailed to news outlets and government buildings killing five people and infecting 17 others. According to a 2012 report, the bioterrorism event cost $3.2 million in cleanup and decontamination. At the time, no testing system was in place that officials could use to screen the letters.
Ultraviolet light (UV) has not only harmful effects on molecules and biological tissue like human skin but it also can impair the performance of organic solar cells upon long-term exposure. Researchers in Germany have now developed a so-called plasmonic metamaterial which is compatible with solar technology and completely absorbs UV light despite being only 20 nm thin.
Twenty-five years after the infamous Exxon Valdez oil spill in Prince William Sound, beaches on the Alaska Peninsula hundreds of kilometers from the incident still harbor small hidden pockets of surprisingly unchanged oil, according to new research being presented at the American Geophysical Union meeting in Hawaii this week.
How heat flows at the nanoscale can be very different than at larger scales, and researchers are working to understand how these features affect the transport of the fundamental units of heat, called phonons. At Cornell Univ. scientists have invented a phonon spectrometer whose measurements are 10 times sharper than standard methods. This boosted sensitivity has uncovered never-before-seen effects of phonon transport.
So-called extremely low-volatility organic compounds, which are produced by plants, have been detected for the first time during field and laboratory experiments in Finland and Germany. The results may help to explain discrepancies between observations and theories about how volatile organic compounds produced by vegetation are converted into atmospheric aerosol. This in turn should improve existing climate models.
Researchers report that one tiny variation in the sequence of a gene may cause some people to be more impaired by traumatic brain injury than others with comparable wounds. The study, described in PLOS ONE, measured general intelligence in a group of 156 Vietnam War veterans who suffered penetrating head injuries during the war.
In its 48th year, the Laboratory of the Year Awards continue to recognize excellence in research laboratory design, planning and construction. Judging for this year’s competition took place on Thursday, February 20th and was conducted by a blue-ribbon panel of laboratory architects, engineers, equipment manufacturers, researchers and the editors of R&D Magazine and Laboratory Design Newsletter.
If you’ve run out of drinking water during a lakeside camping trip, there’s a simple solution: Break off a branch from the nearest pine tree, peel away the bark and slowly pour lake water through the stick. The improvised filter should trap any bacteria, producing fresh, uncontaminated water. In fact, a team has discovered that this low-tech filtration system can produce up to 4 L of drinking water a day.
Tear apart an electric car's rechargeable battery and you'll find a mineral normally associated with No. 2 pencils. It's graphite. And experts say the promise of expanded uses for "pencil lead" in lithium-ion batteries, as well as a decrease in supply from China, has helped touch off the largest wave of mining projects in decades.
Cornell Univ. researchers have recently led what is probably the most comprehensive study to date of block copolymer nanoparticle self-assembly processes. The work is important, because using polymers to self-assemble inorganic nanoparticles into porous structures could revolutionize electronics.
A DNA test of a pregnant woman's blood is more accurate than current methods of screening for Down syndrome and other common disorders, new research finds. If other studies bear this out, it could transform prenatal care by giving a more reliable, non-invasive way to detect these problems very early in pregnancy.
