Researchers have developed an augmented reality (AR) visor system that enables them to manipulate the light coming off food in such a way as to 'trick' people consuming the food into experiencing it as more or less moist, watery, or even delicious. The findings not only reveal how human taste is experienced in a multisensorial way -- through a combination of visual perception, smell and even sound -- but the technique could be used in hospitals to improve the palatability of food, or as a design development tool in the food industry.
By André Julião | Agência FAPESP – A drug used to treat pulmonary hypertension significantly reduced the capacity of tumor cells to migrate and invade other tissues in trials involving pancreatic, ovarian, breast cancer, and leukemia cell lines. Furthermore, in mice with an aggressive form of breast cancer, the drug reduced the incidence of metastasis in the liver and lungs by 47% and lengthened survival compared with untreated animals.
Silicon single-electron/hole transistors (SETs/SHTs) and super-high frequency nanoelectromechanical resonators show great potentials in quantum computation, sensing and many other areas.
Recently, a group led by Prof. GUO Guoping from the University of Science and Technology of China of the Chinese Academy of Sciences, collaborating with Prof. ZHANG Zhen's group from Uppsala University, Sweden, designed and fabricated CMOS-compatible suspended SHT devices which worked as super-high frequency nanoelectromechanical resonators. The work was published in Advanced Materials.
TAMPA, Fla. -- Prostate cancer is one of the most common cancers among men in the United States. One in nine men will be diagnosed during his lifetime. When diagnosed, a patient's disease is graded from 1 to 5 based on how aggressive it is, with 5 being the most aggressive. Those with grades 4/5 disease are at the highest risk of poor outcomes or death from the disease; however, there are no immunologic or genomic indicators that can help physicians determine the best course of treatment for this group of patients.
In the present world we are witnessing headlines which regularly chronicle technology-based issues such as security hacks, inappropriate or illegal surveillance, misuse of personal data, spread of misinformation, algorithmic bias, and lack of transparency.
ITHACA, N.Y. - By borrowing nature's blueprints for photosynthesis, Cornell University bioengineers have found a way to efficiently absorb and store large-scale, low-cost renewable energy from the sun - while sequestering atmospheric carbon dioxide to use later as a biofuel.
The key: Let bioengineered microbes do all the work.
HOUSTON - (Dec. 15, 2020) - You have to look closely, but the hills are alive with the force of van der Walls.
Rice University scientists found that nature's ubiquitous "weak" force is sufficient to indent rigid nanosheets, extending their potential for use in nanoscale optics or catalytic systems.
CAMBRIDGE, MA -- In some ways, learning to program a computer is similar to learning a new language. It requires learning new symbols and terms, which must be organized correctly to instruct the computer what to do. The computer code must also be clear enough that other programmers can read and understand it.
WASHINGTON, DC--Plastics contain and leach hazardous chemicals, including endocrine-disrupting chemicals (EDCs) that threaten human health. An authoritative new report, Plastics, EDCs, & Health, from the Endocrine Society and the IPEN (International Pollutants Elimination Network), presents a summary of international research on the health impacts of EDCs and describes the alarming health effects of widespread contamination from EDCs in plastics.
Diverting urine away from municipal wastewater treatment plants and recycling the nutrient-rich liquid to make crop fertilizer would result in multiple environmental benefits when used at city scale, according to a new University of Michigan-led study.
BOSTON - Adding a contrast-enhancing agent to magnetic resonance imaging (MRI) significantly improves image quality and allows radiologists who interpret MRI scans to pick up subtle anatomic details and abnormalities that might otherwise be missed.
Editor's Note: This study and its survey were conducted prior to Institutional Review Board (IRB) approval, a necessary step in the University's compliance protocols to ensure federal regulations and ethical principles are followed. Because the survey was conducted prior to the required approval, the principal investigator has voluntarily retracted the manuscript. An internal review will follow.
Eddies are often seen as the weather of the ocean. Like large-scale circulations in the atmosphere, eddies swirl through the ocean as slow-moving sea cyclones, sweeping up nutrients and heat, and transporting them around the world.
The European Union recently adopted more ambitious climate goals for 2030 - their implementation is now the focus of debate. What do the Member States need to consider? A new study shows how important it is that governments coordinate policy reforms to support renewable electricity. Otherwise, many investors are likely to shift their focus to technologies that will continue to be subsidized or to countries where subsidies are still available. This outcome would increase the overall costs of expanding renewable electricity generation in Europe.
December 15, 2020 - How much time do primary care physicians actually spend one-on-one with patients? Analysis of timestamp data from electronic health records (EHRs) provides useful insights on exam length and other factors related to doctors' use of time, reports a study in the January issue of
