Huixin He, associate professor, nanoscale chemistry at Rutgers University, Newark, and Tamara Minko, professor at the Rutgers Ernest Mario School of Pharmacy, have developed a nanotechnology approach that potentially could eliminate the problems of side effects and drug resistance in the treatment of cancer. Under traditional chemotherapy, cancer cells, like bacteria, can develop resistance to...
Dark matter, for more than 70 years as mysterious and unknowable a subject to science as the legendary island of Atlantis has been to history, is bringing 140 scientists from the U.S., Europe and Asia to the Marriott Hotel in Marina del Rey for the ninth UCLA Symposium on Sources and Detection of Dark Matter and Dark Energy in the Universe. The three-day conference runs through Friday, Feb. 26.
Virtual reality game technology using Wii may help recovering stroke patients improve their motor function, according to research presented as a late breaking poster at the American Stroke Association's International Stroke Conference 2010.
Using an accelerated, shorter course of radiation therapy for patients with advanced head and neck cancer allows doctors to reduce the amount of chemotherapy, thus reducing toxicity, according to a study presented at the Multidisciplinary Head and Neck Cancer Symposium.
(PhysOrg.com) -- A single cell in the human body is approximately 10,000 times more energy-efficient than any nanoscale digital transistor, the fundamental building block of electronic chips. In one second, a cell performs about 10 million energy-consuming chemical reactions, which altogether require about one picowatt (one millionth millionth of a watt) of power.
Microsoft on Thursday said it combined technology with an "extraordinary" legal maneuver to cripple a massive network of hacked computers that had been flooding the Internet with spam.
Visitors to national parks and forests are encouraged to use bear spray when they encounter grizzlies, but disposing of the bear spray canisters is a problem that three Montana State University engineering students addressed for their senior capstone project, sponsored by the Gallatin National Forest.
(PhysOrg.com) -- Physicists from the Japanese-led multinational T2K collaboration announced today that they had made the first detection of a neutrino which had travelled all the way under Japan from their neutrino beamline at the J-PARC facility in Tokai village (about an hour north of Tokyo by train) to the gigantic Super-Kamiokande underground detector near the west coast of Japan, 295 km (185...
(AP) -- Apple Inc. said Thursday that it has sold 10 billion songs from the iTunes Store since it opened in 2003, cementing its position as the world's largest music retailer.
(PhysOrg.com) -- Exerting delicate control over a pair of atoms within a mere seven-millionths-of-a-second window of opportunity, physicists at the University of Wisconsin-Madison created an atomic circuit that may help quantum computing become a reality.
Carnegie Mellon University researchers are tracking how US industry uses scarce water resources.
New research using magnetic resonance imaging (MRI) shows that childhood stress such as abuse or emotional neglect, in particular when combined with genetic factors, can result in structural brain changes, rendering these people more vulnerable to developing depression. The study led by scientists at Trinity College Dublin has just been published in the international scientific...
People talk to their plants, pray to humanlike gods, name their cars, and even dress their pets up in clothing. We have a strong tendency to give nonhuman entities human characteristics (known as anthropomorphism), but why? In a new report in Current Directions in Psychological Science, a journal of the Association for Psychological Science, psychological scientists Adam Waytz from Harvard...
Stories of environmental damage and their consequences always seem to take place far away and in another country, usually a tropical one with lush rainforests and poison dart frogs.
A collaboration between the Center for Robotic Surgery at Roswell Park Cancer Institute and the University at Buffalo's School of Engineering and Applied Sciences has produced one of the world's first simulators that closely approximates the "touch and feel" of the da Vinci robotic surgical system.
Researchers from the Ohio State University have developed a rapid, multiplexed genotyping method to identify the single nucleotide polymorphisms (SNPs) that affect warfarin dose. The related report by Yang et al, "Rapid Genotyping of SNPs Influencing Warfarin Drug Response by SELDI-TOF Mass Spectrometry," appears in the March 2010 issue of the Journal of Molecular Diagnostics.
The maximal standardized uptake value (called SUVmax) measured from FDG PET readings taken from the primary tumor in head and neck squamous cell carcinoma patients before treatment is a strong predictor of disease-specific survival, overall survival and disease-free survival, while pretreatment SUVmax for lymphodenopathy is strongly associated with distant metastasis, according to a study...
(PhysOrg.com) -- For years, it has been thought that senior citizens don't require as much sleep as younger adults. However, a study at the University of California San Diego is turning that assumption on its head. For older folks, it appears that the amount of sleep they get is quite important when it comes to memory and other cognitive processing activities. What's not as important as we age is...
A skipper hoping to become the first to sail round the world using solar power said his catamaran could carve a wake for pollution-free shipping as he unveiled the record-breaking yacht Thursday.
Technology designed to detect nuclear explosions and enforce the world's nuclear test-ban treaty now will be pioneered to monitor active volcanoes in the Northern Mariana Islands near Guam. The island of Guam soon will be the primary base for forward deployment of U.S. military forces in the Western Pacific.
(PhysOrg.com) -- A test of the SWAT (Soil and Water Assessment Tool) model on a small watershed with poor water quality in Maryland showed that the model accurately estimated pollutant levels over the long term, according to Agricultural Research Service (ARS) scientists and cooperators.
(PhysOrg.com) -- When you snap a photo of your daughter Lucy with your smart phone camera, Polar Rose software can identify her face and automatically store her photo in your Lucy file. Now, Polar Rose along with another Swedish company TAT (The Astonishing Tribe) has taken the Polar Rose software one step beyond... into augmented ID.
Ever looked carefully at the leaves on a plant and noticed their various sizes and shapes? Why are they different? What controls the size and shape of each individual leaf? Very little is known about the developmental control of leaf size and shape, and understanding the mechanisms behind this is a major issue in plant biology.
Promiscuous females may be the key to a species' survival, according to new research by the Universities of Exeter and Liverpool. Published today (25 February) in Current Biology, the study could solve the mystery of why females of most species have multiple mates, despite this being more risky for the individual.
