Pandemic screen time tops 6 hours a day for some kindergartners
2021-05-12
COLUMBUS, Ohio - Kindergartners from low-income families spent more than six hours a day in front of screens during two early months of the COVID-19 pandemic, a small Ohio study suggests.
That is nearly double the screen time found before the pandemic in similar children, according to other research.
Caregivers from low-income households may have faced more difficulties than those from more advantaged families in managing the time their children spent watching TV and using computers, phones and tablets when child care was shut down, according to the researchers.
Still, the results are concerning, said Rebecca Dore, lead author of the study and senior research ...
What does your voice say about you?
2021-05-12
Everyone has at some point been charmed by the sound of a person's voice: but can we believe our ears? What can a voice really reveal about our character? Now an international research team led by the University of Göttingen has shown that people seem to express at least some aspects of their personality with their voice. The researchers discovered that a lower pitched voice is associated with individuals who are more dominant, extrovert and higher in sociosexuality (more interested in casual sex). The findings were true for women as well as for men. The results were published in the Journal of Research in Personality.
The researchers analysed data from over 2,000 participants and included ...
CNIO researchers discover the cause of neuronal death in a large proportion of familial ALS patients
2021-05-12
In Amyotrophic Lateral Sclerosis (ALS), the progressive death of neurons that control body movement leads to paralysis of muscles in the limbs and gradually of the whole body, which ultimately makes it impossible to breathe. ALS is currently untreatable, and its cause is unknown.
It is known, however, that in 10% of affected individuals there is a strong genetic component, which causes the disease to occur in several members of a single family. In about half of these cases of familial ALS, the origin lies in a gene called C9ORF72. But why do mutations in this gene kill motor neurons?
The answer may have been found by the Genomic Instability Group headed by Óscar Fernández-Capetillo at the Spanish National Cancer Research Centre (CNIO), who discovered ...
Harnessing the hum of fluorescent lights for more efficient computing
2021-05-12
The property that makes fluorescent lights buzz could power a new generation of more efficient computing devices that store data with magnetic fields, rather than electricity.
A team led by University of Michigan researchers has developed a material that's at least twice as "magnetostrictive" and far less costly than other materials in its class. In addition to computing, it could also lead to better magnetic sensors for medical and security devices.
Magnetostriction, which causes the buzz of fluorescent lights and electrical transformers, occurs when a material's shape and magnetic field are linked--that is, a change in shape causes a change in magnetic field. The property could be key to a new generation of computing devices called ...
Artificial intelligence tool uses chest X-ray to differentiate worst cases of COVID-19
2021-05-12
Trained to see patterns by analyzing thousands of chest X-rays, a computer program predicted with up to 80 percent accuracy which COVID-19 patients would develop life-threatening complications within four days, a new study finds.
Developed by researchers at NYU Grossman School of Medicine, the program used several hundred gigabytes of data gleaned from 5,224 chest X-rays taken from 2,943 seriously ill patients infected with SARS-CoV-2, the virus behind the infections.
The authors of the study, publishing in the journal npj Digital Medicine online May 12, cited the "pressing need" ...
Ancestors may have created 'iconic' sounds as bridge to first languages
2021-05-12
The 'missing link' that helped our ancestors to begin communicating with each other through language may have been iconic sounds, rather than charades-like gestures - giving rise to the unique human power to coin new words describing the world around us, a new study reveals.
It was widely believed that, in order to get the first languages off the ground, our ancestors first needed a way to create novel signals that could be understood by others, relying on visual signs whose form directly resembled the intended meaning.
However, an international research team, led by experts from the University of Birmingham and the Leibniz-Centre General Linguistics (ZAS), Berlin, have discovered that iconic ...
Brand new physics of superconducting metals refuted by Lancaster physicists
2021-05-12
Lancaster scientists have demonstrated that other physicists' recent "discovery" of the field effect in superconductors is nothing but hot electrons after all.
A team of scientists in the Lancaster Physics Department have found new and compelling evidence that the observation of the field effect in superconducting metals by another group can be explained by a simple mechanism involving the injection of the electrons, without the need for novel physics.
Dr Sergey Kafanov, who initiated this experiment, said: "Our results unambiguously refute the claim of the electrostatic field effect ...
AI learns to type on a phone like humans
2021-05-12
Touchscreens are notoriously difficult to type on. Since we can't feel the keys, we rely on the sense of sight to move our fingers to the right places and check for errors, a combination of efforts we can't pull off at the same time. To really understand how people type on touchscreens, researchers at Aalto University and the Finnish Center for Artificial Intelligence (FCAI) have created the first artificial intelligence model that predicts how people move their eyes and fingers while typing.
The AI model can simulate how a human user would type any sentence on any keyboard design. It makes errors, detects them -- though not always immediately -- and corrects them, very much like ...
Telemedicine needs to be integrated into cardiology training, experts recommend
2021-05-12
Philadelphia, May 12, 2021 - The COVID-19 pandemic has resulted in an abrupt change in healthcare delivery, including a shift from in-person visits to telemedicine. However, a Canadian survey found that a significant proportion of cardiology trainees are uncomfortable with using telemedicine and feel that better preparation for new-tech medicine is needed. Experts draw attention to the need for a telemedicine curriculum that includes supervision to prepare trainees for the expanding role of telemedicine in cardiovascular care. Survey results are published in the Canadian Journal of Cardiology.
"Our outpatient care shifted almost overnight from in-person visits to providing care to patients via telephone or video platforms (known as telemedicine) as a result ...
New study: Kefir package claims don't always accurately reflect composition of commercial products
2021-05-12
Philadelphia, May 12, 2021 - In recent years there has been an increased interest in the consumption of kefir, a fermented dairy beverage, because there is some evidence that it has health benefits and its affordability. A new study by researchers from the University of Illinois and The Ohio State University, published in JDS Communications, found that 66 percent of the commercial kefir products studied overstated microorganism density and 80 percent contained bacterial species that were not included on the label, potentially misleading consumers.
Senior author Kelly S. Swanson, PhD, University of Illinois, Urbana, ...
Pink drinks can help you run faster and further, study finds
2021-05-12
A new study led by the Centre for Nutraceuticals in the University of Westminster shows that pink drinks can help to make you run faster and further compared to clear drinks.
The researchers found that a pink drink can increase exercise performance by 4.4 per cent and can also increase a 'feel good' effect which can make exercise seem easier.
The study, published in the journal Frontiers in Nutrition, is the first investigation to assess the effect of drink colour on exercise performance and provides the potential to open a new avenue of future research in the field of sports drinks and exercise.
During the study participants were asked to run on a treadmill for 30 minutes at a self-selected speed ensuring their rate of exertion remained consistent. Throughout the exercise ...
Petting therapy dogs enhances thinking skills of stressed college students
2021-05-12
For college students under pressure, a dog may be the best stress fighter around.
Programs exclusively focused on petting therapy dogs improved stressed-out students' thinking and planning skills more effectively than programs that included traditional stress-management information, according to new Washington State University research.
The study was published today in the journal AERA Open, a peer-reviewed journal of the American Educational Research Association. The paper demonstrated that stressed students still exhibited these cognitive skills improvements up to six weeks after completion of the four-week-long program.
"It's a really powerful finding," said Patricia Pendry, associate professor in WSU's Department of ...

2021-05-12
ROCHESTER, Minn. ­­­-- Patients diagnosed with post-COVID-19 syndrome, also known as "PCS," "COVID-19 long-haul syndrome" and "Post-Acute Sequelae of SARS COV-2," experience symptoms such as mood disorders, fatigue and perceived cognitive impairment that can negatively affect returning to work and resuming normal activities, according to a Mayo Clinic study published in Mayo Clinic Proceedings.
The study reports on the first 100 patients to participate in Mayo Clinic's COVID-19 Activity Rehabilitation program (CARP), one of the first multidisciplinary programs established to evaluate ...
NTU study of ancient corals in Indonesia reveals slowest earthquake ever recorded
2021-05-12
A 'slow-motion' earthquake lasting 32 years - the slowest ever recorded - eventually led to the catastrophic 1861 Sumatra earthquake, researchers at the Nanyang Technological University, Singapore (NTU Singapore) have found.
The NTU research team says their study highlights potential missing factors or mismodelling in global earthquake risk assessments today.
'Slow motion' earthquakes or 'slow slip events' refer to a type of long, drawn-out stress release phenomenon in which the Earth's tectonic plates slide against one another without causing major ground shaking or destruction. They typically involve movements of between ...
New findings linking brain immune system to psychosis
2021-05-12
New research at Karolinska Institutet in Sweden suggests a link between psychosis and a genetic change that affects the brain's immune system. The study published in Molecular Psychiatry may impact the development of modern medicines for bipolar disorder or schizophrenia.
Psychosis affects approximately 2-3 per cent of the population and is characterized by a change in the perception of reality, often with elements of hallucinations and paranoid reactions.
Most of the people affected are patients with schizophrenia, but people with bipolar disorder may also experience psychotic symptoms.
The antipsychotics available today often have insufficient efficacy, and for patients, ...
Southern African dinosaur had irregular growth
2021-05-12
Anyone who's raised a child or a pet will know just how fast and how steady their growth seems to be. You leave for a few days on a work trip and when you come home the child seems to have grown 10cm! That's all well and good for the modern household, but how did dinosaurs grow up? Did they, too, surprise their parents with their non-stop growth?
A new study lead by Dr Kimberley Chapelle of the American Museum of Natural History in New York City and Honorary Research Fellow at the University of the Witwatersrand suggests NOT. At least for one iconic southern African dinosaur species. By looking at the fossil ...
How to thermally cloak an object
2021-05-12
Can you feel the heat? To a thermal camera, which measures infrared radiation, the heat that we can feel is visible, like the heat of a traveler in an airport with a fever or the cold of a leaky window or door in the winter.
In a paper published in Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, an international group of applied mathematicians and physicists, including Fernando Guevara Vasquez and Trent DeGiovanni from the University of Utah, report a theoretical way of mimicking thermal objects or making objects invisible to thermal measurements. And it doesn't ...
The Lancet: More nurses lead to fewer patient deaths&readmissions, shorter hospital stays, and savings
2021-05-12
A study across 55 hospitals in Queensland, Australia suggests that a recent state policy to introduce a minimum ratio of one nurse to four patients for day shifts has successfully improved patient care, with a 7% drop in the chance of death and readmission, and 3% reduction in length of stay for every one less patient a nurse has on their workload.
The study of more than 400,000 patients and 17,000 nurses in 27 hospitals that implemented the policy and 28 comparison hospitals is published in The Lancet. It is the first prospective evaluation of the ...
COVID-19 vaccine does not damage the placenta in pregnancy
2021-05-12
CHICAGO --- A new Northwestern Medicine study of placentas from patients who received the COVID-19 vaccine during pregnancy found no evidence of injury, adding to the growing literature that COVID-19 vaccines are safe in pregnancy.
"The placenta is like the black box in an airplane. If something goes wrong with a pregnancy, we usually see changes in the placenta that can help us figure out what happened," said corresponding author Dr. Jeffery Goldstein, assistant professor of pathology at Northwestern University Feinberg School of Medicine and a Northwestern Medicine pathologist. "From what we can tell, the COVID vaccine does not damage the placenta."
The study will be published May 11 in the journal Obstetrics ...
Discovery of new geologic process calls for changes to plate tectonic cycle
2021-05-11
TORONTO, ON - Geoscientists at the University of Toronto (U of T) and Istanbul Technical University have discovered a new process in plate tectonics which shows that tremendous damage occurs to areas of Earth's crust long before it should be geologically altered by known plate-boundary processes, highlighting the need to amend current understandings of the planet's tectonic cycle.
Plate tectonics, an accepted theory for over 60 years that explains the geologic processes occurring below the surface of Earth, holds that its outer shell is fragmented into continent-sized blocks of solid rock, called "plates," that slide over Earth's mantle, the rocky inner layer above ...
Phenomenon explains why patients who survive sepsis die sooner after hospital discharge
2021-05-11
An article published in Frontiers in Immunology suggests that sepsis can cause alterations in the functioning of defense cells that persist even after the patient is discharged from hospital. This cellular reprogramming creates a disorder the authors call post-sepsis syndrome, whose symptoms include frequent reinfections, cardiovascular alterations, cognitive disabilities, declining physical functions, and poor quality of life. The phenomenon explains why so many patients who survive sepsis die sooner after hospital discharge than patients with other diseases or suffer from post-sepsis syndrome, immunosuppression ...
Understanding SARS-COV-2 proteins is key to improve therapeutic options for COVID-19
2021-05-11
COVID-19 has had a significant impact since the pandemic was declared by WHO in 2020, with over 3 million deaths and counting, Researchers and medical teams have been hard at work at developing strategies to control the spread of the infection, caused by SARS-COV-2 virus and treat affected patients. Of special interest to the global population is the developments of vaccines to boost human immunity against SARS-COV-2, which are based on our understanding of how the viral proteins work during the infection in host cells. Two vaccines, namely the Pfizer/BioINtech and Oxford/AZ vaccine rely on the use of delivering the gene that encodes the viral spike protein either as an mRNA or through an adenovirus vector to promote the production of relevant antibodies. The use of monoclonal ...
