Nanosecond pulsed electric fields (nsPEFs) produce strong electrical effects by focusing a high powered electrical pulse over a very short period of time. They are attracting attention as a method of physically stimulating matter in various fields, particularly in the life sciences. Recently, researchers from Kumamoto University in Japan found that stimulating immune cells with nsPEFs can cause them to respond as if they were being stimulated by bacteria.
Astronomers have identified a rare moment in the life of some of the universe's most energetic objects.
Quasars were first observed 60 years ago, but their origins still remain a mystery.
Now researchers at Durham University, UK, have spotted what they suggest is a "brief transition phase" in the development of these galactic giants that could shed light on how quasars and their host galaxies evolve.
The research is published in Monthly Notices of the Royal Astronomical Society.
Human and wildlife conflict has increased along with expanding human populations, particularly when wildlife endanger humans or their livelihoods. Most research on human-wildlife conflict has focused on the ways tigers, wolves, and other predators impact livestock even though noncarnivores also threaten livestock. New research by Dr. Shari Rodriguez and Dr.
A team of researchers, led by international conservation charity ZSL (Zoological Society of London), has discovered that sharks are much rarer in habitats nearer large human populations and fish markets. The team also found that the average body size of sharks and other marine predators fell dramatically in these areas, where sharks are caught and killed intensively for their meat and fins.
The Southwest has always faced periods of drought. Most recently, from late 2011 to 2017, California experienced years of lower-than-normal rainfall.
El Niño is known to influence rain in the Southwest, but it's not a perfect match. New research from the University of Washington and the Woods Hole Oceanographic Institution explores what conditions in the ocean and in the atmosphere prolong droughts in the Southwestern U.S.
A study published in Cell Reports Aug. 6 describes the generation of a new mouse model developed at Hollings Cancer Center that could lead to a better understanding of the cachexia syndrome. This wasting condition, characterized by excessive weight loss, has one of the highest incidences in pancreatic cancer patients.
Former Hurricane Flossie was nothing more than a remnant low pressure area early on Tuesday, August 6. Infrared imagery from NASA's Aqua satellite found just a few scattered areas of cold clouds in thunderstorms in the remnants, now northeast of the Hawaiian Islands.
NASA's Aqua satellite uses infrared light to analyze the strength of storms by providing temperature information about the system's clouds. The strongest thunderstorms that reach high into the atmosphere have the coldest cloud top temperatures.
NASA's Aqua satellite passed over the Northwestern Pacific Ocean and captured a visible image of strengthening Tropical Storm Lekima.
On Aug. 6, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite provided a visible image of Lekima that showed a ring of strong thunderstorms around its center of circulation.
ITHACA, N.Y. - With New York state's $20 million berry industry entering peak season, an invasive fruit fly is thriving.
But little has been known about how the pests survive before and after the growing season.
A Cornell University study, published in Ecological Entomology, investigates for the first time what spotted-wing drosophila adults and larvae eat, and where they lay their eggs, when these short-lived fruits are not in season.
Where there's a will to peddle soybeans in the global marketplace, there's a way, even if a trade war creates roadblocks.
In the recent issue of the international open-access journal Sustainability, Michigan State University (MSU) scholars apply a new, more holistic way to examine global agricultural trade to better understand what's going on when a country as enormous as China develops a big appetite for soybeans.
