Is sitting always bad for your mind? A new study suggests maybe not

by

It’s generally accepted health advice that adults of all ages should sit less, move more, and engage in regular exercise to feel better and reduce the risk of chronic diseases.

However, when it comes to the brain and cognition, a new study of older adults from Colorado State University suggests that some sedentariness isn’t all bad, so long as basic physical activity benchmarks are being met.

The research, from Assistant Professor Aga Burzynska in the CSU Department of Human Development and Family Studies, examined the association between sensor-measured physical activity and cognitive performance in a sample of 228 healthy older adults, aged 60 to 80.

Catholic gynecologists can face moral dilemmas in issues of family planning

by

A study of Catholic obstetrician-gynecologists shows that many face moral dilemmas when dealing with issues of family planning and abortion due to their religious faith, according researchers at the University of Colorado Anschutz Medical Campus.

The study, published this week in JAMA Network Open, revealed that some Catholic Ob/Gyn practitioners lean toward natural methods of birth control and do not perform abortions due to their faith, while others believe providing a full range of services to those in need is intrinsic to their religious teachings.

“The primary outcome was understanding how participants describe integration of Catholic values with family planning service provision,” the study said. [Read more…] about Catholic gynecologists can face moral dilemmas in issues of family planning

UCF researchers are working on tech so machines can thermally ‘breathe’

by

In the era of electric cars, machine learning and ultra-efficient vehicles for space travel, computers and hardware are operating faster and more efficiently. But this increase in power comes with a trade-off: They get superhot.

To counter this, University of Central Florida researchers are developing a way for large machines to “breathe” in and out cooling blasts of water to keep their systems from overheating.

The findings are detailed in a recent study in the journal Physical Review Fluids. [Read more…] about UCF researchers are working on tech so machines can thermally ‘breathe’

How mobile apps grab our attention

by

As part of an international collaboration, Aalto University researchers have shown that our common understanding of what attracts visual attention to screens, in fact, does not transfer to mobile applications.

Despite the widespread use of mobile phones and tablets in our everyday lives, this is the first study to empirically test how users’ eyes follow commonly used mobile app elements.

Previous work on what attracts visual attention, or visual saliency, has centered on desktop and web-interfaces. [Read more…] about How mobile apps grab our attention

The human heart in space: What can we learn from mathematical modeling

by Leave a Comment

Human spaceflight has been fascinating man for centuries, representing the intangible need to explore the unknown, challenge new frontiers, advance technology and push scientific boundaries further.

A key aspect of long-term human spaceflight is the physiological response and the consequent microgravity (0G) adaptation, which has all the features of accelerated aging involving almost every body system: muscle atrophy and bone loss, onset of balance and coordination problems, loss of functional capacity of the cardiovascular system.

A research published in recent days in npj Microgravity – a prestigious journal of the Nature group “Cardiovascular deconditioning during long-term spaceflight through multiscale modeling”) – and conducted by Caterina Gallo, Luca Ridolfi and Stefania Scarsoglio shows that human spaceflight reduces exercise tolerance and ages astronauts’ heart.

“First of all, I have to say that exercise in general seems to be good for the health of the elderly. And our study results show that on top of that, training regularly at high intensity has an extra positive effect,” says Dorthe Stensvold.

Stensvold is a professor in the Cardiac Exercise Research Group (CERG) at the Norwegian University of Science and Technology (NTNU) and has been looking forward to sharing the results from the Generation 100 study for a while now.

Researchers, healthcare professionals and individuals around the world are eager to learn the answer to the question: Can exercise really give older people a longer and healthier life? Generation 100 is the first major study that can tell us that, and Stensvold has encouraging news. [Read more…] about High intensity training best for older people

Almost half of world heritage sites could lose glaciers by 2100

by Leave a Comment

Glaciers are set to disappear completely from almost half of World Heritage sites if business-as-usual emissions continue, according to the first-ever global study of World Heritage glaciers.

The sites are home to some of the world’s most iconic glaciers, such as the Grosser Aletschgletscher in the Swiss Alps, Khumbu Glacier in the Himalayas and Greenland’s Jakobshavn Isbrae.

The study in the AGU journal Earth’s Future and co-authored by scientists from the International Union for Conservation of Nature (IUCN) combines data from a global glacier inventory, a review of existing literature and sophisticated computer modeling to analyze the current state of World Heritage glaciers, their recent evolution, and their projected mass change over the 21st century.

5G wireless may lead to inaccurate weather forecasts

by Leave a Comment

Upcoming 5G wireless networks that will provide faster cell phone service may lead to inaccurate weather forecasts, according to a Rutgers study on a controversial issue that has created anxiety among meteorologists.

“Our study – the first of its kind that quantifies the effect of 5G on weather prediction error – suggests that there is an impact on the accuracy of weather forecasts,” said senior author Narayan B. Mandayam, a Distinguished Professor at the Wireless Information Network Laboratory (WINLAB), who also chairs the Department of Electrical and Computer Engineering in the School of Engineering at Rutgers University-New Brunswick.

The peer-reviewed study was published this month at the 2020 IEEE 5G World Forum, sponsored by the Institute of Electrical and Electronics Engineers. Fifth-generation cellular wireless technology (5G) stems from new, smarter ways to use the higher (mmWave) frequencies for mobile communications.  [Read more…] about 5G wireless may lead to inaccurate weather forecasts

Ancient human footprints in Saudi Arabia give glimpse of Arabian ecology 120000 years ago

by Leave a Comment

Situated between Africa and Eurasia, the Arabian Peninsula is an important yet understudied region for understanding human evolution across the continents.

Recent research highlighting the role of the Arabian Peninsula in human prehistory shows that humans repeatedly dispersed into the peninsula’s interior at times when its harsh deserts were transformed into lush grasslands.

However, the nature and timing of these dispersals have remained elusive, due to a scarcity of datable material and poor-resolution paleo-ecological data associated with evidence for humans.

Touch-and-know: Brain activity during tactile stimuli reveals hand preferences in people

by Leave a Comment

Have you ever wondered whether the brains of right-handed people work differently from those of left-handers? Is it possible to distinguish between them by observing their brain activity in response to stimuli or tasks?

These are important questions from the perspectives of both basic sciences and application-based fields such as brain-computer interfaces, rehabilitation robotics, and augmented reality.

Since the past few years, a team of scientists at Daegu Gyeongbuk Institute of Science and Technology (DGIST), Korea, has been actively conducting fundamental research to answer these questions.
