Adolescent binge drinking disrupts mouse memory in adulthood

EurekAlert! - Dom, 06/17/2018 - 22:00
Excessive drinking during adolescence may interfere with the activity of brain cells needed for sustaining short term memory, according to new research in adolescent male mice published in JNeurosci. The study could help scientists better understand the development of alcohol use disorders in adults.

A research team at Massachusetts Eye and Ear has shown that microglia, the primary immune cells of the brain and retina, play a protective role in response to retinal detachment.

Unique immune-focused AI model creates largest library of inter-cellular communications

EurekAlert! - Dom, 06/17/2018 - 22:00
New data published in Nature Biotech, represents the largest ever analysis of immune cell signaling research, mapping more than 3,000 previously unlisted cellular interactions, and yielding the first ever immune-centric modular classification of diseases. These data serve to rewrite the reference book on immune-focused inter-cellular communications and disease relationships.New Data Published by Nature Biotechnology: Covering 16,000,000 scientific articles, this massive Natural Language Processing (NLP) project quadruples the reference body of organized inter-cellular signalling interactions, plots inter-cellular immune profiles for 188 diseases and creates the first ever immune-centered map of disease similarities and differences.

Targeting the engine room of the cancer cell

EurekAlert! - Dom, 06/17/2018 - 22:00
Researchers at Columbia University Irving Medical Center (CUIMC) have developed a highly innovative computational framework that can support personalized cancer treatment by matching individual tumors with the drugs or drug combinations that are most likely to kill them.

Plant-based diets improve cardiometabolic risk factors in diabetes patients

EurekAlert! - Dom, 06/17/2018 - 22:00
New review in the journal Clinical Nutrition finds that plant-based diets improve cardiometabolic risk factors in those with type 2 diabetes.

UNH researcher captures best ever evidence of rare black hole

EurekAlert! - Dom, 06/17/2018 - 22:00
Scientists have been able to prove the existence of small black holes and those that are super-massive but the existence of an elusive type of black hole, known as intermediate-mass black holes (IMBHs) is hotly debated. New research coming out of the Space Science Center at the University of New Hampshire shows the strongest evidence to date that this middle-of-the-road black hole exists, by serendipitously capturing one in action devouring an encountering star.

NASA finds Tropical Depression Carlotta's strong storms over Mexico, Eastern Pacific

EurekAlert! - Dom, 06/17/2018 - 22:00
Tropical Depression Carlotta continues to hug the coast of southwestern Mexico and drop heavy rainfall. NASA's Aqua satellite provided a look at cloud top temperatures through infrared imagery to find out where the most powerful parts of Tropical Depression Carlotta were located.

Novel information about the effects of in vitro fertilization on embryonic growth

EurekAlert! - Dom, 06/17/2018 - 22:00
In vitro fertilization affects the regulatory region of genes essential for placental and embryonic growth, as well as the birth weight. A new study suggests that the effects depend on genetic variation inherited from the parents. This information could be useful in development of assisted reproduction technologies.

Addgene keeps flow of CRISPR plasmids fast and affordable

EurekAlert! - Dom, 06/17/2018 - 22:00
As a key global enabler of the revolutionary genome editing technology known as CRISPR, the nonprofit organization Addgene has made available more than 100,000 CRISPR plasmids (circular DNA fragments) to 3,400 laboratories worldwide.

Risky opioid prescriptions linked to higher chance of death

EurekAlert! - Dom, 06/17/2018 - 22:00
Most people who misuse opioids are first exposed to the drugs through prescriptions so improving prescribing is targeted as one way to help curb the nation's opioid abuse epidemic. A new study identified six types of risky opioid prescriptions and found that all were linked to a higher chance of death, including fatal opioid overdoses. The study found more than 6 percent of Massachusetts adults received a risky opioid prescription during a five-year period.

Neuroscientists map brain's response to cold touch

EurekAlert! - Dom, 06/17/2018 - 22:00
Carnegie Mellon neuroscientists have mapped the feeling of cool touch to the brain's insula in a mouse model. The findings provide an experimental model that will advance research into conditions like pain and hypersensitivity to cold and help researchers to continue to unravel the multifaceted ways touch is represented in the brain.

Researchers explore whether smarter animals are bigger troublemakers

EurekAlert! - Dom, 06/17/2018 - 22:00
A new paper in the journal Animal Behaviour examines whether smarter animals might be better at learning to live in cities -- but, at the same time, also may come into more conflict with humans.

New method to preserve boy cancer patient fertility being developed at Ben-gurion U.

EurekAlert! - Dom, 06/17/2018 - 22:00
"Our results demonstrate, for the first time, the presence of biologically active SPGCs in testicular biopsies of chemotherapy-treated PCPBs, and their capacity to develop in vitro to different stages of spermatogenesis, including the generation of sperm-like cells," according to lead researcher Prof. Mahmoud Huleihel, a member of BGU's Shraga Segal Department of Microbiology, Immunology and Genetics. "This study may open the way for new therapeutic strategies for fertility preservation of PCPBs and for azoospermic patients."

Compilation of research discussed at the Global Forum On Nicotine: Warsaw June 16 2018

EurekAlert! - Dom, 06/17/2018 - 22:00
Below is a summary of the new and recent research discussed at this conference.

Organic crystals twist, bend, and heal

EurekAlert! - Dom, 06/17/2018 - 22:00
Crystals are brittle and inelastic? A novel class of smart, bendable crystalline organic materials has challenged this view. Now, scientists have engineered a molecular soft cocrystalline structure that bends and twists reversibly and without disintegration when stimulated by high temperature, mechanical force, or under UV light. This multifunctional quality makes it a robust candidate for advanced molecular electronics and other new materials, as the authors reported in the journal Angewandte Chemie.

Research shows how a moderate dose of alcohol protects the heart

EurekAlert! - Dom, 06/17/2018 - 22:00
Results published in Cardiovascular Research suggest the effect is associated with activation of the enzyme ALDH2, which helps rid the organism of an aldehyde which is a toxic byproduct of alcohol digestion as much as it is a byproduct of heart cells submitted to stress.

Violence against women significantly more likely after high-risk sex

EurekAlert! - Dom, 06/17/2018 - 22:00
A study of the victimization of women who were living in areas of high poverty and HIV prevalence in multiple cities across the US has shown that high-risk-sex, characterized by one or more HIV risk factors, was associated with a significantly greater likelihood of physical violence against the female participant within the subsequent six months.

Researchers create novel combination as potential therapy for high-risk neuroblastoma

EurekAlert! - Dom, 06/17/2018 - 22:00
Researchers at VCU Massey Cancer Center in Richmond, Virginia, have identified a promising target to reverse the development of high-risk neuroblastoma and potentially inform the creation of novel combination therapies for the disease.
