Smaller than a grain of sand, phytoplankton are key to aquatic health

Scientists are inching closer to revealing the elusive mechanisms that tiny marine species activate to transform organic contaminants in water into less toxic chemicals. Cup sea water in your hands and you will be holding a bustling world of single-cell organisms – thousands of them. Much like creatures of an undersea metropolis, microscopic photosynthetic microbes […]

“Alien” invasions and the need for planetary biosecurity

The era of space exploration brings with it a new risk: invasion. The peril comes not from little green men arriving on flying saucers but, rather, from microbiological contamination of Earth from extraterrestrial environments and vice versa. Writing in BioScience, Anthony Ricciardi, of McGill University, and colleagues describe the dangers posed by such organisms and […]

Holographic camera sees the unseen with high precision

Northwestern University researchers have invented a new high-resolution camera that can see the unseen — including around corners and through scattering media, such as skin, fog or potentially even the human skull. Called synthetic wavelength holography, the new method works by indirectly scattering coherent light onto hidden objects, which then scatters again and travels back […]

Exercise increases the body’s own ‘cannabis’ which reduces chronic inflammation

Exercise increases the body’s own cannabis-like substances, which in turn helps reduce inflammation and could potentially help treat certain conditions such as arthritis, cancer and heart disease. In a new study, published in Gut Microbes, experts from the University of Nottingham found that exercise intervention in people with arthritis, did not just reduce their pain, but it […]

Fasting-mimicking Diet Is Safe, May Modulate Metabolism and Boost Antitumor Immunity in Cancer Patients

A diet involving short-term, severe calorie restriction was safe, feasible, and resulted in a decrease of blood glucose and growth factor concentration, reduction in peripheral blood immunosuppressive cells, and enhanced intratumor T-cell infiltration in cancer patients receiving standard-of-care therapy, according to the results of a clinical trial published in Cancer Discovery, a journal of the American Association for […]

Life on Mars search could be misled by false fossils

Mars explorers searching for signs of ancient life could be fooled by fossil-like specimens created by chemical processes, research suggests. Rocks on Mars may contain numerous types of non-biological deposits that look similar to the kinds of fossils likely to be found if the planet ever supported life, a study says. Telling these false fossils […]

Micro-Housing for an Aging Population

Responding to the demands of an increasingly older population for options to accommodate aging in place, The University of Texas at Arlington’s College of Architecture, Planning and Public Affairs (CAPPA) is leading a cross-disciplinary research project to design and build micro-housing that can be embedded with technology that allows older people to live safely and […]

Invention lets people pay for purchases with a high-five

Imagine your car starting the moment you get in because it recognizes the jacket you’re wearing. Consider the value of a hospital gown that continuously measures and transmits a patient’s vital signs. These are just two applications made possible by a new “body area network”-enabling fabric invented by engineers at the University of California, Irvine. […]
