In fact, under the right conditions, theoretical physicists say that deleting data can actually produce negative heat--that is, it can have a cooling effect. That’s right, this is a quantum mechanics post.
A test-tube circuit made of DNA-based logic gates can calculate the square root of numbers up to 15, using DNA replication and sequence binding to conduct computations. It’s excruciatingly slow — a calculation can take up to 10 hours
Despite using advanced technology that lets planes practically fly themselves, airline pilots are still bogged down by a lingering 20th-century artifact: Paper. Now at least one commercial airline is adopting cockpit iPads
Nanotechnology, organic chemistry, thermoelectrics and, yes, fashion are all in play here, as scientists and designers come up with clothing that can protect humans’ health, generate electricity and even keep things nice and clean.
Future hybrid cars won’t just have powerful batteries — they will be storing energy in their doors, hoods and roofs. Car parts could serve as capacitors, which would allow for smaller and more lightweight batteries, thus increasing a hybrid’s range.
Sprinklers that read your lawn's mind, 3-D phones, speakers that adjust the sound for your location and more
Handmade according to an exacting process, Kramer chef's knives sell for $10,000 or more. They're beloved by chefs and collectors for their keen edges, thoughtful design, and beautiful finish
A 2009 study by a group of Leeds University researchers found that higher levels of Vitamin D were linked to improved skin cancersurvival odds. Other studies have found that Vitamin D has a connection to a strong immune response in the body. In fact,
"A positive association has been observed between exposure to the agent and cancer for which a causal interpretation is considered ... to be credible," states the IARC. However, in the same train of thought, the agency claims that evidence is "lim
Antimatter, an elusive type of matter that's rare in the universe, has now been trapped for more than 16 minutes — an eternity in particle physics. In fact, scientists who've been trapping antihydrogen atoms at the European Organization for Nucle
"For a long time, researchers have known that sleep deprivation results in increased levels of adenosine in the brain, and has this effect from fruit flies to mice to humans." Abel said. "There is accumulating evidence that this adenosine is reall
This stretch of mtDNA is one of the most extremely conserved in the entire genome, with only one difference among the 33 human haplogroups, one in Neanderthal, and two in Denisova. Yet, somehow, the Starchild mtDNA (see red arrow at bottom of chart b
Nanoparticles of silver are being found increasingly in the environment-and in environmental science laboratories. Because they have a variety of useful properties, especially as antibacterial and antifungal agents, silver nanoparticles increasingly
Focardi and Rossi have demonstrated a device that produces copper which they say is due to the fusion of atomic nuclei of nickel and hydrogen, the ingredients that feed their reactor.The 'Missing Mass' has been transformed into energy: it is in the
Despite Michele Bachman flirting with possibility of running for President, what most don't know is that her educational policies are being openly challenged by a high school student from Baton Rouge, La.
New Zealand’s Martin Aircraft Company has tested a jetpack that can soar to 5,000 feet and cruise at more than 60 mph.
he drug, a type of histone deacetylase (HDAC) inhibitor being evaluated in numerous ongoing clinical trials, has been shown to reverse the harmful effects of autophagy in heart muscle cells of mice. Autophagy is a natural process by which cells eat t
And just two ounces of tomato paste or a pint of juice a day could be enough to help many patients. The secret lies in high levels of the compound lycopene which gives ripe tomatoes their bright red colour. This powerful anti-oxidant is essential
The whale sharks spied in one group off the Yucatán Peninsula in Mexico two years ago numbered up to 420 — the largest gathering of the mysterious behemoths ever recorded, scientists said.
A $10 million prize would go to the first device that can diagnose a range of diseases with the same accuracy as a team of doctors.
A new chemistry could result in batteries that don't overheat—opening up new uses, including electric cars.
New thermoelectric materials will be tested in BMW, Ford, and Chevrolet vehicles by the end of summer.
A startup hopes to commercialize a novel design that features fluid electrodes.
specially made nanoribbons with smooth edges using a scanning tunnelling microscope (STM). These ribbons were obtained from Hongjie Dai's group at Stanford University, where they were produced by chemically unzipping carbon nanotubes (rolled up shee
The small size will give designers freedom they haven’t had since the dawn of the auto age. Traditional bulbs rely on burning filaments, glass globes and reflectors. Many car makers, of course, will continue on with traditional styles. A car without
Upon further investigation, the team discovered that while the glutamate-mediated change in horizontal cell voltage did have a negative feedback effect, glutamate exposure also caused an additional, more subtle change in the horizontal cells, increas
The study, which was recently published in the journal PLoS One, explains that when a highly-bioavailable "nano-complex" of naringenin is consumed just before a meal that is high in fat and sugar, it can reduce the development of bad cholesterol by
and mimic Parkinson’s disease does so by rapidly damaging cellular energy generators called mitochondria. This damage impairs the ability of mitochondria to circulate around the cell as they normally would. As a result, axons, the extended arms nerve
Using lung tissue from surgical samples, researchers identified and isolated the human lung stem cell and tested the functionality of the stem cell both in vitro and in vivo.
Scientists have discovered how to decode human brainwaves and intelligence agencies are rubbing their hands. In possibly the greatest potential breakthrough for spy agencies, mind-reading machines are about to become a reality. According to research
