UNH researcher captures best ever evidence of rare black hole

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

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

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

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

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

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

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.

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

Below is a summary of the new and recent research discussed at this conference.

Organic crystals twist, bend, and heal

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

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

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

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.

BIDMC researchers develop decision-making tool to benefit patients with HCV

Dom, 06/17/2018 - 22:00
BIDMC researchers led a retrospective analysis of four randomized clinical trials focused on the effects of DAA therapies in patients with HCV-associated liver failure, and developed a new means of predicting improvement in liver function in response to DAA treatment.

Algorithm speeds up process for analyzing 3D medical images

Dom, 06/17/2018 - 22:00
In a pair of upcoming conference papers, MIT researchers describe a machine-learning algorithm that can register brain scans and other 3D images more than 1,000 times more quickly using novel learning techniques.

Rare mutation of gene carried by Quebec family gives insight into how the brain is wired

Dom, 06/17/2018 - 22:00
The study of a Quebec family with an unusual gene provides novel insight into how our brain is built and, according to the McGill-led team of scientists, offers a better understanding of psychiatric disorders such as depression, addictions and schizophrenia.

Daily fasting works for weight loss

Dom, 06/17/2018 - 22:00
A new study shows that daily fasting is an effective tool to reduce weight and lower blood pressure. The study is the first to examine the effect of time-restricted eating on weight loss in obese individuals.

Hunting molecules to find new planets

Dom, 06/17/2018 - 22:00
It's impossible to obtain images of an exoplanet, so dazzling is the light of its star. However, astronomers led by UNIGE have the idea of detecting molecules that are present in the planet's atmosphere in order to make it visible, provided that these same molecules are absent from its star. Thanks to this innovative technique, the device is sensitive to the selected molecules, making the star invisible and allowing the astronomers to observe the planet.

New study suggests ovarian hormone may make drug withdrawal symptoms worse for women

Dom, 06/17/2018 - 22:00
Researchers found that a form of the estrogen hormone can contribute to drug relapse in females by worsening withdrawal symptoms. The study looked at the interaction of the female sex hormone estradiol and methamphetamine.

Cementless fly ash binder makes concrete 'green'

Dom, 06/17/2018 - 22:00
