UMN researchers discover important connection between cells in the liver

Mié, 11/14/2018 - 23:00
University of Minnesota Medical School researchers have made a discovery which could lead to a new way of thinking about how disease pathogenesis in the liver is regulated, which is important for understanding the condition nonalcoholic fatty liver disease (NAFLD), which is incredibly common and growing. It is apparent that about 30 percent of Americans and are at risk to advance to more severe conditions such as nonalcoholic steatohepatitis (NASH), cirrhosis, cardiovascular disease, or even liver cancer.

NASA keeps watch over space explosions

Mié, 11/14/2018 - 23:00
NASA's Magnetospheric Multiscale mission has been observing a type of space explosion called magnetic reconnection for three years. MMS just witnessed such an explosion in a unique location: the part of Earth's magnetic environment trailing behind the planet, away from the Sun -- with enough resolution to reveal its true nature more clearly.

Can artificial intelligence help victims of abuse to disclose traumatic testimony?

Mié, 11/14/2018 - 23:00
Can artificial intelligence be a useful tool to help young victims tell their stories? What if AI could support forensic interviewers with tools to help gather information in an appropriate manner? This is paper documents what is believed to be the first attempt to develop and apply custom software to automatically detect and categorize speech patterns in the course of forensic interviews.

Trans-galactic streamers feeding most luminous galaxy in the universe

Mié, 11/14/2018 - 23:00
ALMA data show the most luminous galaxy in the universe has been caught in the act of stripping away nearly half the mass from at least three of its smaller neighbors.

UNH scientists help provide first-ever views of elusive energy explosion

Mié, 11/14/2018 - 23:00
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving 'magnetic reconnection' -- the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion -- in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Cotton-based hybrid biofuel cell could power implantable medical devices

Mié, 11/14/2018 - 23:00
A glucose-powered biofuel cell that uses electrodes made from cotton fiber could someday help power implantable medical devices such as pacemakers and sensors. The new fuel cell, which provides twice as much power as conventional biofuel cells, could be paired with batteries or supercapacitors to provide a hybrid power source for the medical devices.

Cosmic fireworks

Mié, 11/14/2018 - 23:00
It's not every day you get to observe a gamma-ray binary system. In fact, it's a once-in-a-lifetime experience comparable to seeing Halley's Comet or a solar eclipse. Here's what a UD team saw.

Astronomers find possible elusive star behind supernova

Mié, 11/14/2018 - 23:00
Astronomers may have finally uncovered the long-sought progenitor to a specific type of exploding star by sifting through NASA Hubble Space Telescope archival data. The supernova, called a Type Ic, is thought to detonate after its massive star has shed or been stripped of its outer layers of hydrogen and helium.

Bursting bubbles launch bacteria from water to air

Mié, 11/14/2018 - 23:00
A new MIT study shows how bubbles contaminated with bacteria can act as tiny microbial grenades, bursting and launching microorganisms, including potential pathogens, out of the water and into the air.

Ulcers from diabetes? New shoe insole could provide healing on-the-go

Mié, 11/14/2018 - 23:00
Purdue University researchers have developed a shoe insole that could help make the healing process more portable for the 15 percent of Americans who develop ulcers as a result of diabetes.

Scientists find mysterious family of proteins are cellular pressure sensors

Mié, 11/14/2018 - 23:00
Scientists at Scripps Research have discovered that a mysterious family of cellular proteins called OSCAs and TMEM63s are a novel class of mechanosensitive ion channels. The scientists also deciphered the atomic structure of one member of the OSCA protein family, an advance that will allow them to study how these ion channels do their jobs, information that could be critical to identifying how dysfunctions in mechanosensing play a role in disease.

Historian tells new story about England's venerated 'Domesday book'

Mié, 11/14/2018 - 23:00
Nearly a thousand years ago, a famous king created a famous book, later given the title 'Domesday' (pronounced 'doomsday'). It's among the most famous documents in English history, but its origins had not been thoroughly investigated. University of Illinois history professor Carol Symes makes the case that it came years later than the 1087 date to which it's attributed. The process that produced it also exposed a load of grievance from a conquered people.

Ashkenazi Jewish founder mutation identified for Leigh Syndrome

Mié, 11/14/2018 - 23:00
Decades after two brothers died in childhood of a mitochondrial disease, researchers pinpointed the exact cause in a founder mutation among Ashkenazi Jews. The discoverers say the mutation should be added to prenatal carrier screening programs for prospective parents.

NASA finds a cloud-filled eye in Tropical Cyclone Gaja

Mié, 11/14/2018 - 23:00
Tropical Cyclone Gaja continued to organize in the Bay of Bengal as it made its approach to southeastern India when NASA-NOAA's Suomi NPP satellite passed overhead and captured an image. The image revealed that Gaja had developed a cloud-filled eye.

Making moves and memories, are they connected?

Mié, 11/14/2018 - 23:00
Researchers report the first direct evidence that the cerebellum does more than just control muscle activity. It also plays a role in cognitive functions.

Faecal transplant may protect premature babies from fatal bowel disease

Mié, 11/14/2018 - 23:00
Children born prematurely often experience serious problems with the gastrointestinal tract and therefore have increased risk of developing life-threatening bowel infection. Now researchers from the University of Copenhagen have shown, in a study on pigs, that transplantation of faeces from healthy pigs changes the bowel's bacterial composition in those born prematurely and protects them from the fatal bowel disease necrotizing enterocolitis (NEC).

Scorpion venom to shuttle drugs into the brain

Mié, 11/14/2018 - 23:00
The Peptides and Proteins lab at the Institute for Research in Biomedicine (IRB Barcelona) has published a paper in Chemical Communications describing the capacity of a small protein (a peptide) derived from chlorotoxin, found in scorpion venom (Giant Yellow Israeli scorpion), to carry drugs across the blood-brain barrier (BBB).

Humpback whales arrive in the Mediterranean to feed themselves

Mié, 11/14/2018 - 23:00
Although the presence of humpback whales in the Mediterranean has been considered unusual, it is known that their visits have increased in the last 150 years. A recent study indicates that what motivates these cetacean mammals to enter these waters is the search for food.

Climate change/biodiversity loss: Inseparable threats to humanity that must be addressed together

Mié, 11/14/2018 - 23:00
Demand for biofuels to fight climate change clouds the future for biodiversity, says the Executive Secretary of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES). The demand could cause a 10- to 30-fold expansion of green energy-related agricultural land use, adding crushing pressure on habitat for plants and animals and undermining the essential diversity of species on Earth.Anne Larigauderie made the remarks at a major UN biodiversity meeting in Egypt.

Bloomberg American Health Initiative releases special public health reports supplement

Mié, 11/14/2018 - 23:00
With US life expectancy now on the decline for two consecutive years, the Bloomberg American Health Initiative is releasing a supplement to Public Health Reports, the scholarly journal of the US Surgeon General. The supplement includes a series of special articles addressing five of the most complex and urgent health challenges facing the United States, specifically: addiction and overdose, violence, obesity and the food system, environmental challenges, and risks to adolescent health.
