Saffron from Spain is one of the world's most superior varieties, but the majority of this product which is labelled and exported as such originates in other countries. Scientists from the Czech Republic and Spain confirmed this false labelling after analysing 44 commercial products. By using a new technique based on each type of saffron's unique chemical 'fingerprint', the scientists have proved that over 50% of the samples were fraudulent.
AURORA, Colo. (Jan. 20, 2016) - Researchers from the University of Colorado Anschutz Medical Campus have shown a direct link between indoor tanning and substance abuse among Colorado high school students.
"A growing national body of evidence links indoor tanning with other risky health-related behavior among adolescents," said study author Robert Dellavalle, MD, associate professor of dermatology at the University of Colorado School of Medicine.
Scientists at ETH Zurich have developed a new method of 3D microprinting. This can be used to manufacture even tiny, partly overhanging structures easily and in a single step. One day, this could pave the way for the manufacture of complex watch components or microtools for keyhole surgery, for example.
Quantum computing will change lives, society and the economy and a working system is expected to be developed by 2020 according to a leading figure in the world of quantum computing, who will talk tomorrow Jan. 21, 2016 at the World Economic Forum (WEF) in Davos, Switzerland.
Researchers from the University of Granada (UGR) have proven that frying in Extra Virgin Olive Oil (EVOO) is the cooking method that increases the phenolic fraction present in raw vegetables used in Mediterranean diet (potato, pumpkin, tomato and eggplant) the most. This means an improvement to this foods in the cooking process.
CAMBRIDGE, Ma. - Jan. 20, 2016 - During a 2014 talk on his exploration of deep-sea coral reefs, Baruch College marine biologist David Gruber showed a video of clunky robotic hands collecting fragile specimens of coral and sponges from the ocean floor. Harvard engineer and roboticist Robert J. Wood was in the audience -- the two scientists were being recognized as Emerging Explorers by the National Geographic Society -- and a lightbulb went off.
A one-of-a-kind instrument built at CSU lets scientists map cellular composition in three dimensions at the nanoscale, allowing researchers to watch how cells respond to new medications at the most minute level ever observed.
The new mass-spectral imaging system is the first of its kind in the world and its applications are just beginning to surface, said Carmen Menoni, a University Distinguished Professor in the Department of Electrical and Computer Engineering.
Heartbeats can now be measured without placing sensors on the body, thanks to a new technology developed in Japan. Researchers at the Kyoto University Center of Innovation, together with Panasonic Corp, have come up with a way to measure heartbeats remotely, in real time, and under controlled conditions with as much accuracy as electrocardiographs.
The researchers say this will allow for the development of "casual sensing" -- taking measurements as people go about their daily activities, for instance, when they are going to bed or getting ready to start the day.
WEST LAFAYETTE, Ind. - Researchers have created nanoribbons of an emerging class of materials called topological insulators and used a magnetic field to control their semiconductor properties, a step toward harnessing the technology to study exotic physics and building new spintronic devices or quantum computers.
The falling price of gasoline at the pumps may warm the hearts of consumers but it chills the souls of scientists who recognize that humankind must curtail the burning of fossil fuels to reduce the threat of climate change. Biofuels can help mitigate climate change and provide us with a sustainable source of transportation energy if yields and production costs are economically competitive. A major step towards achieving this goal has been achieved by researchers with the U.S. Department of Energy (DOE)'s Joint BioEnergy Institute (JBEI).
It took Jackie Goordial over 1000 Petri dishes before she was ready to accept what she was seeing. Or not seeing. Goordial, a post-doctoral fellow in the Department of Natural Resource Sciences at McGill University has spent the past four years looking for signs of active microbial life in permafrost soil taken from one of the coldest, oldest and driest places on Earth: in University Valley, located in the high elevation McMurdo Dry Valleys of Antarctica, where extremely cold and dry conditions have persisted for over 150,000 years.
Billions of people use the internet, which requires huge data centres and results in an enormous energy consumption. In her doctoral dissertation at Umeå University in Sweden, Mina Sedaghat has developed techniques and algorithms to manage and schedule the resources in these large data centres at a lesser cost, more efficiently, more reliably and with a lower environmental impact.
BINGHAMTON, N.Y. - Researchers at Binghamton University have become the first to use an open-source graphics processor unit (GPU) for research.
Scientists at the Energy Department's National Renewable Energy Laboratory (NREL) are studying what may seem paradoxical - certain defects in silicon solar cells may actually improve their performance.
The findings run counter to conventional wisdom, according to Pauls Stradins, the principal scientist and a project leader of the silicon photovoltaics group at NREL.
A Southampton study using high resolution imaging to create a "virtual bone biopsy" has shed new light on why people with type 2 diabetes are at risk of bone fractures.
Researchers from the Medical Research Council Lifecourse Epidemiology Unit, University of Southampton, used high resolution peripheral quantitative computed tomography (HRpQCT) to assess bone structure and strength at a microstructural level in living patients.
