Statements about biofuels being carbon neutral should be taken with a grain of salt. This is according to researchers at the University of Michigan Energy Institute after completing a retrospective, national-scale evaluation of the environmental effect of substituting petroleum fuels with biofuels in the US. America's biofuel use to date has in fact led to a net increase in carbon dioxide emissions, says lead author John DeCicco in Springer's journal Climatic Change.

CAMBRIDGE, Mass. -- The MIT researchers were trying to develop a new battery, but it didn't work out that way. Instead, thanks to an unexpected finding in their lab tests, what they discovered was a whole new way of producing the metal antimony -- and potentially a new way of smelting other metals, as well.

AMHERST, Mass. - In a paper presented today at the Association for Computing Machinery's special interest group on data communication (SIGCOMM) conference in Florianópolis, Brazil, a team of computer science researchers at the University of Massachusetts Amherst led by professor Deepak Ganesan introduced a new radio technology that allows small mobile devices to take advantage of battery power in larger devices nearby for communication.

(Washington, DC)--The world population will reach 9.9 billion in 2050, up 33 percent from an estimated 7.4 billion now, according to projections included in the latest World Population Data Sheet from the Population Reference Bureau (PRB).

The world population would hit the 10 billion mark in 2053 if the assumptions underlying PRB's 2050 projections are applied to subsequent years.

How can we store solar energy for period when the sun doesn't shine? One solution is to convert it into hydrogen through water electrolysis. The idea is to use the electrical current produced by a solar panel to 'split' water molecules into hydrogen and oxygen. Clean hydrogen can then be stored away for future use to produce electricity on demand, or even as a fuel.

Washington, DC - August 23, 2016 - Findings from a new study, reported in the journal mBio, may help food companies improve the quality of dairy products. The researchers have discovered that bacteria in raw milk arriving at dairy processing facilities are highly diverse and differ according to season, but still contain a core microbiota.

Some water ferns can absorb large volumes of oil within a short time, because their leaves are strongly water-repellent and, at the same time, highly oil-absorbing. Researchers of KIT, together with colleagues of Bonn University, have found that the oil-binding capacity of the water plant results from the hairy microstructure of its leaves. It is now used as a model to further develop the new Nanofur material for the environmentally friendly cleanup of oil spills. (DOI: 10.1088/1748-3190/11/5/056003)

It's a familiar hazard of vacation time: While you're conspicuously absent, your colleagues in the office forget to water and fertilize the plants - often leaving behind nothing but a brownish skeleton. Whether a plant thrives or wastes away depends above all on whether its roots get enough water and nutrients. Geophysicists at the University of Bonn have now visualized such processes for the first time using electrical impedance tomography. The researchers have now published their results in the scientific journal Biogeosciences.

Researchers have designed a thin plastic membrane that stops rechargeable batteries from discharging when not in use and allows for rapid recharging.

The patent-pending technology controls how charge flows inside a battery, and was inspired by how living cell membranes transport proteins in the body. It could find applications in high powered "supercapacitors" for electric cars and even help prevent the kinds of fires that plagued some models of hoverboards recently.

Like all data networks, the networks that connect servers in giant server farms, or servers and workstations in large organizations, are prone to congestion. When network traffic is heavy, packets of data can get backed up at network routers or dropped altogether.

CAMBRIDGE, Mass. -- One of the most promising approaches to curbing the flow of human-made greenhouse gases into the atmosphere is to capture these gases at major sources, such as fossil-fuel-burning power plants, and then inject them into deep, water-saturated rocks where they can remain stably trapped for centuries or millennia.

A team of physicists from ITMO University (Saint Petersburg) and Moscow Institute of Physics and Technology (MIPT) has demonstrated the potential of silicon nanoparticles for effective non-linear light manipulation. Their work lays the foundation for the development of novel optical devices with a wide range of functionalities. These silicon nanoparticles based devices would allow to transmit, reflect, or scatter incident light in a specified direction, depending on its intensity.

LOS ALAMOS, N.M., August 23, 2016--A new class of fuel cells based on a newly discovered polymer-based material could bridge the gap between the operating temperature ranges of two existing types of polymer fuel cells, a breakthrough with the potential to accelerate the commercialization of low-cost fuel cells for automotive and stationary applications.

PHILADELPHIA -- Each year more than 300,000 Americans will succumb to out-of-hospital sudden cardiac death (SCD) -- the immediate and unexpected cessation of the heart's ability to function properly -- one of the leading causes of death in the United States. For the first time, a team of researchers led by Rajat Deo, MD, MTR, an assistant professor of Cardiovascular Medicine in the Perelman School of Medicine at the University of Pennsylvania, has developed and validated a prediction model to determine sudden cardiac death risk in adults without a history of cardiovascular disease (CVD).

PHILADELPHIA, Aug. 22, 2016 -- In developing nations, the current test to diagnose tuberculosis (TB) is error-prone, complicated and time-consuming. Furthermore, patients in these resource-limited areas can't easily travel back to a clinic at a later date to get their results. To make diagnoses simpler, faster and more accurate, chemists have developed a quick and easy diagnostic tool. Field trials of the experimental new test began in June in South Africa, which has a high incidence of TB.
