Researchers are trying to plant a digital seed for artificial intelligence by letting a massive computer system browse millions of pictures and decide for itself what they all mean. The system at Carnegie Mellon Univ. is called NEIL, short for Never Ending Image Learning. In mid-July, it began searching the Internet for images continuously and, in tiny steps, is deciding for itself how those images relate to each other.
For months, all eyes in the sky have pointed at the comet that's zooming toward a blisteringly close encounter with the sun. The moment of truth comes Thursday, Thanksgiving Day. The sun-grazing Comet ISON, now thought to be less than a mile wide, will either fry and shatter, victim of the sun's incredible power, or endure and quite possibly put on one fabulous celestial show. Talk about an astronomical cliffhanger.
SunPartner Technologies and 3M Company have announced an agreement to collaborate in product development and technical solutions based on engineered electronics materials from 3M and transparent solar cell technologies from Sunpartner Technologies. The two companies are developing a sustainable wireless transparent micro component that will charge devices while they are being used and exposed to light.
According to a recent study, fashions in research funding, reward structures in universities and streamlining of scientific agendas undermine traditional academic norms and may result in science bubbles. New research shows how the mechanisms that set off the financial crisis might be replicating in the field of science.
Converting solar energy into storable fuel remains one of the greatest challenges of modern chemistry. Chemists have commonly tried to use indium tin oxide (ITO) because it has transparency, but it also expensive and rare. Researchers at Duke Univ. has created something they hope can replace ITO: copper nanowires fused in a see-through film.
Viruses can not only cause illnesses in humans, they also infect bacteria. Bacteria protect themselves with a kind of immune system that detects and “chops up” foreign DNA. Scientists have now shown that the dual-RNA guided enzyme Cas9 which is involved in the process has developed independently in various strains of bacteria. This enhances the potential of exploiting the bacterial immune system for genome engineering.
For years scientists have intensely argued over whether increases of potent methane gas concentrations in the atmosphere, from about 5,000 years ago to the start of the industrial revolution, were triggered by natural causes or human activities. A new study suggests the increase in methane likely was caused by both.
A team of researchers have demonstrated a technique that, by measuring the physical properties of individual cells in body fluids, can diagnose cancer with a high degree of accuracy. The technique, which uses a deformability cytometer to analyze individual cells, could reduce the need for more cumbersome diagnostic procedures and the associated costs, while improving accuracy over current methods.
The scientist credited with inventing the World Wide Web, Tim Berners-Lee, says a growing tide of surveillance is threatening democracy's future. Lee, a former R&D Magazine Scientist of the Year said Friday that as more people use the Internet and social media to "expose wrongdoing," some governments are feeling threatened.
Biologists at Brown Univ. have found a way to measure the effects of aging by watching the ebb and flow of chromatin, a structure along strands of DNA that either silences or permits gene expression. In several newly published experiments they show that gene silencing via chromatin in fruit flies declines with age.
A team of researchers has uncovered critical information that could help scientists understand how protein polymers interact with other self-assembling biopolymers. The research helps explain naturally occurring nanomaterial within cells and could one day lead to engineered bio-composites for drug delivery, artificial tissue, bio-sensing, or cancer diagnosis.
A single layer of tin atoms could be the world’s first material to conduct electricity with 100% efficiency at the temperatures that computer chips operate, according to a team of theoretical physicists led by researchers from SLAC National Accelerator Laboratory and Stanford Univ.
In our universe there are particle accelerators 40 million times more powerful than the Large Hadron Collider at CERN. Scientists don’t know what these cosmic accelerators are or where they are located, but new results being reported from IceCube, the neutrino observatory buried at the South Pole, may show the way. These new results should also erase any doubts as to IceCube’s ability to deliver on its promise.
Researchers have created magnetic replicas of sunflower pollen grains using a wet chemical, layer-by-layer process that applies highly conformal iron oxide coatings. The replicas possess natural adhesion properties inherited from the spiky pollen particles while gaining magnetic behavior, allowing for tailored adhesion to surfaces.
A potential rheumatoid arthritis treatment from French drugmaker Sanofi and its U.S. development partner Regeneron Pharmaceuticals Inc. fared better than a fake drug at improving disease signs and symptoms in a late-stage study. The companies said they saw a statistically significant improvement in patient groups that received their drug, sarilumab, combined with methotrexate compared to those who just received methotrexate and a placebo.
