Flickering screens may help children with reading and writing difficulties
2021-06-10
Previous studies have shown that children with attention difficulties and/or ADHD solve cognitive tasks better when they are exposed to auditory white noise. However, this is the first time that such a link has been demonstrated between visual white noise and cognitive abilities such as memory, reading and non-word decoding in children with reading and writing difficulties.
"The white noise to which we exposed the children, also called visual pixel noise, can be compared with giving children glasses. The effect on reading and memory was immediate," explains Göran Söderlund, Senior Lecturer in Education at the University of Gothenburg and Professor of Special Education at the Western Norway University ...
New research shows link between politics, boredom and breaking public-health rules
2021-06-10
People who are more prone to boredom and who are socially conservative are more likely to break public-health rules, according to new psychology research.
While previous research demonstrated a connection between being highly prone to boredom and breaking social-distancing rules, this study demonstrated the association was more prominent as participants' social conservatism increased.
"Many public-health measures such as wearing a mask or getting a vaccine have become highly politicized," said James Danckert, professor of psychology at the University of Waterloo. "People who find these ...
Higher alcohol content beer popularity growing, as overall beer consumption down
2021-06-10
PITTSBURGH, June 10, 2021 - Americans are consuming more craft beer with higher alcohol content but are drinking less beer by volume, according to a new analysis led by epidemiologists at the University of Pittsburgh Graduate School of Public Health.
The study, published online and in a coming issue of the journal Substance Use & Misuse, looked at beer purchased in stores between 2004 and 2014. This is the first study to examine trends not only in the volume of beer purchased, but also the "beer specific" alcohol content.
"With the rise in popularity of craft breweries and the acquisition of such breweries by large-scale ...

India's national government has inappropriately prioritised people for covid-19 vaccination
Current approach is causing huge numbers of avertable deaths, warn experts
India's national government has inappropriately prioritised people for covid-19 vaccination, argue doctors and researchers in The BMJ today.
Peter Lloyd-Sherlock and colleagues warn that the government's current approach to vaccination - focusing on younger age groups - "is causing huge numbers of avertable deaths and is deeply inequitable."
From 3 May to 5 June 2021, more first doses were administered to people under 45 than over 60, even though at ...

2021-06-10
HOUSTON -- Results from the multi-cohort Phase I/II ARROW clinical trial, conducted by The University of Texas MD Anderson Cancer Center researchers, showed that a once-daily dose of pralsetinib, a highly selective RET inhibitor, was safe and effective in treating patients with advanced RET fusion-positive non-small cell lung cancer (NSCLC) and RET-altered thyroid cancer. The findings for each cohort were published today in The Lancet Oncology and The Lancet Diabetes & Endocrinology, respectively.
"Targeted therapies have dramatically improved care for patients with NSCLC and thyroid cancer driven by oncogenes, and the rapid clinical translation of selective RET inhibitor ...
Liquid water on exomoons of free-floating planets
2021-06-10
The moons of planets that have no parent star can possess an atmosphere and retain liquid water. Astrophysicists at LMU have calculated that such systems could harbor sufficient water to make life possible - and sustain it.
Water - in liquid form - is the elixir of life. It made life possible on Earth and is indispensable for the continuing existence of living systems on the planet. This explains why scientists are constantly on the lookout for evidence of water on other solid bodies in the Universe. Up to now, however, the existence of liquid water on planets other than Earth has not been directly proven. However, ...

The findings were published today in JAMA Surgery.
Christopher Conner, MD, PhD, neurosurgery resident in the Vivian L. Smith Department of Neurosurgery at McGovern Medical School at UTHealth and the study's lead author, said the research is timely as more individuals are utilizing ridesharing apps.
"Automobile accidents are the leading cause of death and disability among young people, so anything we can do to reduce those incidents ...
Protein in prostate cancer may inhibit tumor growth
2021-06-10
Prostate cancer is the second most common cancer among men, according to the American Cancer Society. It's also one of the trickiest cancers to diagnose and treat.
But new research from the University of Georgia has identified a protein that appears to prevent the cancer from spreading to and colonizing the bone, providing a new target for future therapeutics.
"Unfortunately, prostate cancer that has spread to the bone is very aggressive, often lethal and very difficult to treat," said Brian Cummings, corresponding author of the study and head of the College of Pharmacy's pharmaceutical and biomedical sciences department. "Even in cases of successful treatment, the patient's quality of life is severely lessened due to bone loss."
Prostate cancer that hasn't spread beyond nearby ...
Breakthrough study shows defining traits are forged the moment we're born
2021-06-10
There are still many unsolved mysteries about the human brain and its development. Now, a novel study published in Frontiers in Psychiatry sheds new light on the neurobiological origins of our individual traits.
Functional connectivity is the coordinated activity - activation or deactivation - through time between separate brain regions, regardless of their physical closeness or the type of neural connections between them. Changes in functional connectivity can be a sign of mental health disorders such as depression, eating disorders, and schizophrenia, and are thought to have developmental origins.
We know that mental health is characterized by three functional brain networks. The first is hypoconnectivity ...
Predisposition to addiction may be genetic
2021-06-10
People who have a high sensation-seeking personality trait may be more likely to develop an addiction to cocaine, according to a Rutgers study.
"Although many people try illicit drugs like cocaine or heroin, only a small proportion develop an addiction," said lead author Morgan James, a member of the Rutgers Brain Health Institute and an assistant professor in the department of psychiatry at Rutgers Robert Wood Johnson Medical School. "The interaction found between sensation-seeking traits and the drug-taking experience show that predisposition to addiction has a genetic basis, and that this interacts with environmental factors such as patterns of drug use. The sensation-seeking trait was predictive of rats' likelihood to exhibit stronger ...
Socially engaged older women more likely to be emotionally abused or mistreated
2021-06-10
For older adults, participating in social activities can protect against physical and mental signs of aging, but it may also pose risks, especially for women.
A new analysis of national data led by UC San Francisco found that older women who were broadly engaged in social activities before the COVID pandemic had 76 percent higher odds of experiencing emotional abuse or mistreatment than women who were less engaged.
The paper is published June 9, 2021 in the Journal of the American Geriatrics Society.
"Given widespread discussion about the negative effects of social isolation of ...
Endangered blue whales recorded off southwest coast of India
2021-06-10
Research from the University of Washington shows that endangered blue whales are present and singing off the southwest coast of India. The results suggest that conservation measures should include this region, which is considering expanding tourism.
Analysis of recordings from late 2018 to early 2020 in Lakshadweep, an archipelago of 36 low-lying islands west of the Indian state of Kerala, detected whales with a peak activity in April and May.
The study was published in May in the journal Marine Mammal Science.
"The presence of blue whales in Indian waters is well known from several strandings and some live sightings of blue whales," said lead author Divya Panicker, a ...
New insight into biosynthesis and architecture of photosynthetic membranes in bacteria
2021-06-10
A new study conducted by the researchers at the University of Liverpool reveals how the ancient photosynthetic organisms - cyanobacteria - evolve their photosynthetic machinery and organise their photosynthetic membrane architecture for the efficient capture of solar light and energy transduction.
Oxygenic photosynthesis, carried out by plants, algae, and cyanobacteria, produces energy and oxygen for life on Earth and is arguably the most important biological process. Cyanobacteria are among the earliest phototrophs that can perform oxygenic photosynthesis and make significant contributions to the Earth's atmosphere and primary production.
Light-dependent photosynthetic reactions are performed by a set of photosynthetic ...

Researchers take quantum encryption out of the lab
2021-06-10
WASHINGTON -- In a new study, researchers demonstrate an automated, easy-to-operate quantum key distribution (QKD) system using the fiber network in the city of Padua, Italy. The field test represents an important step toward implementing this highly secure quantum communication technology using the type of communication networks already in place in many regions around the world.
QKD offers impenetrable encryption for data communication because it uses the quantum properties of light to generate secure random keys for encrypting and decrypting data.
"QKD can be useful in any situation where security is paramount because it offers unconditional security for the key exchange process," ...
Breast cancer risk in African-Americans tied to genetic variations
2021-06-10
Two gene variants found in African American women may explain why they are more likely to be diagnosed with triple negative breast cancer (TNBC) than white women of European ancestry, according to Weill Cornell Medicine and NewYork-Presbyterian investigators. The study findings may have implications for developing better risk assessment tools for TNBC in African American women and for understanding why they have poorer TNBC outcomes.
In a study, published April 29 in Scientific Reports, the investigators found that a version of the ANKLE1 gene that can be protective against TNBC is less likely to be found in African American women than white women of European ancestry. In addition, African American women with a mutation in the Duffy gene, which plays a role in inflammation, ...
GEM simplifies the internal structure of protons and their collisions
2021-06-10
Inside each proton or neutron there are three quarks bound by gluons. Until now, it has often been assumed that two of them form a "stable" pair known as a diquark. It seems, however, that it's the end of the road for the diquarks in physics. This is one of the conclusions of the new model of proton-proton or proton-nucleus collisions, which takes into account the interactions of gluons with the sea of virtual quarks and antiquarks.
In physics, the emergence of a new theoretical model often augurs badly for old concepts. This is also the case with the description of collisions of protons with protons or atomic nuclei, proposed by scientists from the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) ...
Ceramics provide insights into medieval Islamic cuisine
2021-06-10
Organic residues on ceramic pottery are a valuable resource for understanding medieval cuisines of Islamic-ruled Sicily, according to a study published June 9, 2021 in the open-access journal PLOS ONE by Jasmine Lundy of the University of York, UK and colleagues.
During the 9th to 12th century AD, Sicily was under Islamic rule. This transition is known to have profoundly impacted the region, and the capital city of Palermo thrived as an economic and cultural center of the Mediterranean Islamic world. But little is known about how the lives of people in the region were impacted during this important time period.
In this study, researchers examined organic residues of plant and animal products on ceramic pottery to gain insights ...
Engineers apply physics-informed machine learning to solar cell production
2021-06-09
Today, solar energy provides 2% of U.S. power. However, by 2050, renewables are predicted to be the most used energy source (surpassing petroleum and other liquids, natural gas, and coal) and solar will overtake wind as the leading source of renewable power. To reach that point, and to make solar power more affordable, solar technologies still require a number of breakthroughs. One is the ability to more efficiently transform photons of light from the Sun into useable energy.Organic photovoltaics max out at 15% to 20% efficiency -- substantial, but a limit on solar energy's potential. Lehigh University engineer Ganesh Balasubramanian, like many others, wondered if there were ways to improve the design of solar cells to make them more ...
Understanding gut inflammation may hold clues to mitigating Parkinson's onset
2021-06-09
GRAND RAPIDS, Mich. (JUNE 8, 2021) -- Chronic inflammation in the gut may propel processes in the body that give rise to Parkinson's disease, according to a study by scientists at Van Andel Institute and Roche.
The study, published in Free Neuropathology, is the latest in a growing list that links the gut and the immune system to Parkinson's. The researchers' findings in an experimental mouse model of gut inflammation track with several large-scale epidemiological studies that show an association between Parkinson's and inflammatory bowel diseases, such as ulcerative colitis and Crohn's disease.
Epidemiological evidence from other groups indicates the risk of developing Parkinson's fades in certain people whose ...
Bacteria-sized robots take on microplastics and win by breaking them down
2021-06-09
Small pieces of plastic are everywhere, stretching from urban environments to pristine wilderness. Left to their own devices, it can take hundreds of years for them to degrade completely. Catalysts activated by sunlight could speed up the process, but getting these compounds to interact with microplastics is difficult. In a proof-of-concept study, researchers reporting in ACS Applied Materials & Interfaces developed self-propelled microrobots that can swim, attach to plastics and break them down.
While plastic products are omnipresent indoors, plastic waste and broken bits now litter the outdoors, too. The smallest of these ...
Social media use one of four factors related to higher COVID-19 spread rates early on
2021-06-09
TORONTO, June 9, 2021 - Researchers from York University and the University of British Columbia have found social media use to be one of the factors related to the spread of COVID-19 within dozens of countries during the early stages of the pandemic.
The researchers say this finding resembles other examples of social media misinformation ranging from the initial phase of vaccine rollout to the 2021 Capitol riot in the United States.
Countries with high social media use leading to off-line political action prior to the pandemic, as surveyed before the pandemic by V-Dem (a database from the University of Gothenburg), showed ...

For early amphibians, a new lifestyle meant a new spine
2021-06-09
Vertebrate life began in the water, but around 340-360 million years ago, four-limbed creatures, or tetrapods, made the transition onto land. In the years that followed, some species adapted to terrestrial life, while others turned back to the water and readapted to an aquatic lifestyle.
A new study of these early amphibians, published in the journal PLOS ONE and led by Penn paleontologist Aja Carter, suggests that these environmental shifts left an impression--on the shape of the animals' spines.
"I'm interested in how the shapes of the vertebrae affect how animals move," she says. "Our findings suggest that, in at least one part of the vertebrae, the shape of the bones ...
