Study observes sudden acceleration of flow, generates new boundary layer

In an experiment on how turbulent boundary layers respond to acceleration in the flow around them, aerospace engineers at the University of Illinois Urbana-Champaign observed an unexpected internal boundary layer. “Not only were we able to identify a new internal boundary layer, but we were able to systematically track its…

New insights into the protein-mediated motor neuron loss in amyotrophic lateral sclerosis: Researchers from Japan have identified the neurological spreading patterns of the disease-causing protein called TDP-43

Our movements are controlled by multiple neural pathways that connect the brain and spinal cord. In particular, neurons in the cerebral cortex send commands to the motor neurons in the spinal cord and then to the muscles, thus eliciting the required movement. However, this flow of neural information is compromised…

Economist group argues for scientific experimentation in environmental policymaking

Environmental regulators and other organizations should do more scientific experimentation to inform natural resource policy, according to an international group of economists that includes University of Wyoming researchers. In a new paper in the  journal Science, the economists say more frequent use of up-front experiments would result in more effective…

Radiation may not be necessary for patients with low-risk breast cancer

Some women with early-stage, low-risk breast cancer may not need radiotherapy after breast conserving surgery according to new research led by McMaster University, BC Cancer, Hamilton Heath Sciences, and the University of British Columbia. The research, published in The New England Journal of Medicine on Aug. 17, shows women 55…

Platelets can replicate the benefits of exercise in the brain

Pre-clinical trials by University of Queensland researchers have found an injection of a specific blood factor can replicate the benefits of exercise in the brain. Dr Odette Leiter and Dr Tara Walker from UQ’s Queensland Brain Institute led a team which discovered platelets, the tiny blood cells critical for blood…

Urban great tits have paler plumage than their forest-living relatives

As urban areas expand, animals increasingly find themselves living in towns and cities. While some animals may benefit from milder temperatures and fewer natural predators in urban settings, they also have to cope with pollutants and changes in their diet. Previous research has shown that animals in cities are “duller”…

How old are you, biologically? AI can tell your ‘true’ age by looking at your chest: AI-powered model using chest X-rays helps develop biomarkers for aging

Osaka Metropolitan University scientists have developed an AI model that accurately estimates a patient’s age, using chest radiographs of healthy individuals collected from multiple facilities. Furthermore, they found a positive relationship between differences in the AI-estimated and chronological ages and a variety of chronic diseases, such as hypertension, hyperuricemia, and…

The modern sea spider had started to diversify by the Jurassic, study finds

An extremely rare collection of 160-million-year-old sea spider fossils from Southern France are closely related to living species, unlike older fossils of their kind. These fossils are very important to understand the evolution of sea spiders. They show that the diversity of sea spiders that still exist today had already…

Pollutants are important to biodiversity’s role in spread of wildlife diseases

Conventional wisdom among ecologists holds that the more species there are inhabiting an ecosystem, the less vulnerable any one species will be to a threat like a parasite. A new study of tadpoles at the University of Wisconsin-Madison illustrates how overlapping biological and environmental factors can complicate how we value…

A healthy diet, reading, and doing sports promote reasoning skills in children

Reasoning skills are crucial skills in learning, academic performance, and everyday problem-solving. According to a recent study conducted at the University of Eastern Finland, improved overall diet quality and reduced consumption of red meat, as well as increased time spent in reading and organised sports enhanced reasoning skills among children…

Anxious people use less suitable section of brain to control emotions

When choosing their behaviour in socially difficult situations, anxious people use a less suitable section of the forebrain than people who are not anxious. This can be seen in brain scans, as shown by the research of Bob Bramson and Sjoerd Meijer at the Donders Institute of Radboud University. For…

Positive metabolic effects of gastric bypass disappear quickly

A new study from Lund University in Sweden raises questions about the efficacy of bariatric operations involving gastric bypass. The results show that the biggest metabolic changes happened directly after surgery. Just a year after the operation, the concentration of metabolites and fats had returned to almost the same levels…
