A new way to transform brewer's spent grain into value-added products

Home brewing enthusiasts and major manufacturers alike experience the same result of the beer-making process: mounds of leftover grain. Once all the flavor has been extracted from barley and other grains, what's left is a protein- and fiber-rich powder that is typically used in cattle feed or put in landfills.

Scientists develop a novel strategy to determine the freshness of beef samples

Scientists at Gwangju Institute of Science and Technology, Korea, combine an inexpensive spectroscopy technique with artificial intelligence to develop a new way of assessing the freshness of beef samples. Their method is remarkably quicker and more cost-effective than conventional approaches while maintaining a relatively high accuracy, paving the way for mass-produced devices to identify spoiled meat both in the industry and at home.

Supercomputer simulations help uncover the mechanism for HIV replication

Viruses lurk in the grey area between the living and the nonliving, according to scientists. Like living things, they replicate but they don't do it on their own. The HIV-1 virus, like all viruses, needs to hijack a host cell through infection in order to make copies of itself.

Processed meat associated with an increased risk of cardiovascular disease

Red meat is a major source of medium- and long-chain saturated fatty acids, which may lead to an increased risk of cardiovascular disease. Processed meat, which has been modified to improve taste or extend its shelf-life, has also been associated with an increased risk of cardiovascular disease.

Simple 'designer' pore reproduces selective cellular transport mechanisms

The nucleus is the headquarters of a cell and molecules constantly move across the nuclear membrane through pores. The transport of these molecules is both selective and fast; some 1,000 molecules per second can move in or out.

New label-free immune profiling assay to assess rapidly changing host immune response

Researchers from Critical Analytics for Manufacturing Personalized-Medicine (CAMP), an Interdisciplinary Research Group (IRG) at the Singapore-MIT Alliance for Research and Technology (SMART), MIT's research enterprise in Singapore, have developed a new label-free immune profiling assay that profiles the rapidly changing host immune response in case of infection, in a departure from existing methods that focus on detecting the pathogens themselves, which can often be at low levels within a host.

Study reveals how lipids and water molecules control 5-hydroxytryptamine receptors

Serotonin, or 5-hydroxytryptamine (5-HT), is a kind of neurotransmitter. 5-HT can regulate multifaceted physiological functions such as mood, cognition, learning, memory, and emotions through 5-HT receptors.
