VLA reveals new object near supermassive black hole in famous galaxy

EurekAlert! - Lun, 05/22/2017 - 22:00
When astronomers took a new look at a famous galaxy with the upgraded Very Large Array, they were surprised by the appearance of a new, bright object that had not appeared in previous images.

Biosynthetic secrets: How fungi make bioactive compounds

EurekAlert! - Lun, 05/22/2017 - 22:00
Biological engineers at Utah State University have successfully decoded and reprogrammed the biosynthetic machinery that produces a variety of natural compounds found in fungi.

How X-rays helped to solve mystery of floating rocks

EurekAlert! - Lun, 05/22/2017 - 22:00
Experiments at Berkeley Lab's Advanced Light Source have helped scientists to solve a mystery of why some rocks can float for years in the ocean, traveling thousands of miles before sinking.

Better science faster

EurekAlert! - Lun, 05/22/2017 - 22:00
Scientists at UCSB's NCEAS are transforming how complex marine data from the Ocean Health Index is synthesized, communicated and used for coastal management.

Special X-ray technique allows scientists to see 3-D deformations

EurekAlert! - Lun, 05/22/2017 - 22:00
In a new study published last Friday in Science, researchers at Argonne used an X-ray scattering technique called Bragg coherent diffraction imaging to reconstruct in 3-D the size and shape of grain defects. These defects create imperfections in the lattice of atoms inside a grain that can give rise to interesting material properties and effects.

Alzheimer's, Parkinson's, and Huntington's diseases share common crucial feature

EurekAlert! - Lun, 05/22/2017 - 22:00
A study has found that abnormal proteins found in Alzheimer's, Parkinson's and Huntington's diseases share a similar ability to cause damage when they invade brain cells. The finding suggests that an effective treatment for one neurodegenerative disease might work for other neurodegenerative diseases as well.

Study leads to breakthrough in better understanding acute myeloid leukemia

EurekAlert! - Lun, 05/22/2017 - 22:00
A study led by the University of Birmingham has made a breakthrough in the understanding of how different genetic mutations cause acute myeloid leukemia.

Pope's encyclical boosted his credibility on climate change, especially among liberals

EurekAlert! - Lun, 05/22/2017 - 22:00
The Pope's 2015 encyclical on climate change did not directly influence people's beliefs about the seriousness of climate change or its effect on the poor, a study in Cognition has found. The papal message did, however, indirectly influence people's beliefs about climate change by raising the Pope's credibility on that issue, most strongly among liberals.

Oyster farming to benefit from new genetic screening tool

EurekAlert! - Lun, 05/22/2017 - 22:00
Oyster farmers are set to benefit from a new genetic tool that will help to prevent disease outbreaks and improve yields. The technology -- developed by scientists at the University of Edinburgh's Roslin Institute -- will enable hatcheries to rapidly assess the genetic make-up of their oysters, so they can select animals with desirable characteristics from which to breed.

Paper: DNA may have only modest impact on sexual assault arrests

EurekAlert! - Lun, 05/22/2017 - 22:00
Crime labs' DNA testing may influence arrests in just a small number of sexual assault cases, because most arrests occur before crime lab results are available, suggests a new study led by University of Illinois social work senior research specialist Theodore P. Cross.

Study: Street gangs, crime serve as deviant leisure activities for youths

EurekAlert! - Lun, 05/22/2017 - 22:00
Street gang membership, criminal activities provide deviant leisure activities for at-risk youths, suggests a new study by University of Illinois researchers Liza Berdychevsky, Kim Shinew and Monika Stodolska.

Cowbird moms choosy when selecting foster parents for their young

EurekAlert! - Lun, 05/22/2017 - 22:00
Despite their reputation as uncaring, absentee moms, cowbird mothers are capable of making sophisticated choices among potential nests in order to give their offspring a better chance of thriving, a new study shows.

Discovery of a key regulatory gene in cardiac valve formation

EurekAlert! - Lun, 05/22/2017 - 22:00
Researchers from the University of Basel in Switzerland have identified a key regulator gene for the formation of cardiac valves -- a process crucial to normal embryonic heart development. These results are published in the journal Cell Reports today.

Monash researchers find piece in inflammatory disease puzzle

EurekAlert! - Lun, 05/22/2017 - 22:00
Inflammation is the process by which the body responds to injury or infection but when this process becomes out of control it can cause disease. Monash Biomedicine Discovery Institute researchers, in collaboration with the Monash Institute of Pharmaceutical Sciences, have shed light on a key aspect of the process. Their findings may help guide the development of new treatments of inflammatory diseases such as atherosclerosis, which can lead to heart attack or stroke, and type 2 diabetes.

A new strategy reported to combat influenza and speed recovery

EurekAlert! - Lun, 05/22/2017 - 22:00
St. Jude Children's Research Hospital scientists have used a drug being developed to fight solid tumors to restore normal metabolism in flu-infected cells and reduce viral production without the threat of drug resistance.

Researchers reveal bioelectric patterns guiding worms' regenerative body plan after injury

EurekAlert! - Lun, 05/22/2017 - 22:00
Researchers have succeeded in permanently rewriting flatworms' regenerative body shape by resetting their internal bioelectric pattern memory, causing even normal-appearing flatworms to harbor the 'code' to regenerate as two-headed worms.

Improve evolution education by teaching genetics first

EurekAlert! - Lun, 05/22/2017 - 22:00
Evolution is a difficult concept for many students at all levels, however, a study publishing on May 23 in the open access journal PLOS Biology has demonstrated a simple cost-free way to significantly improve students' understanding of evolution at the secondary level: teach genetics before you teach them evolution.

Among all cancers, lung cancer appears to put patients at greatest suicide risk

EurekAlert! - Lun, 05/22/2017 - 22:00
A lung cancer diagnosis appears to put patients at the greatest risk of suicide when compared to the most common types of non-skin cancers, according to new research presented at the ATS 2017 International Conference.

First study shows tie between probiotic and improved symptoms of depression

EurekAlert! - Lun, 05/22/2017 - 22:00
This is the first study showing improved depression scores with a probiotic. It adds to the whole field of microbiota-gut-brain axis, providing evidence that bacteria affect behavior.

Immunotherapy target suppresses pain to mask cancer

EurekAlert! - Lun, 05/22/2017 - 22:00
Duke University researchers found that a molecule called PD-L1, which is blocked by the immunotherapy drug nivolumab, acts not only on immune cells but also on the nerve cells that signal pain. That insight could lead to a simple test that measures subtle differences in pain sensitivity to gauge whether or not a cancer patient is responding to immunotherapy. This study also identifies PD-L1 as a previously unrecognized neuromodulator and pain inhibitor.
