For most vertebrates, losing a limb is permanent, but a lucky few species -- such as salamanders and tadpoles -- have the ability to completely regrow complex body parts. Understanding the molecular mechanisms underlying this phenomenon may be the key to developing new kinds of regenerative medicine, giving us the power to heal spinal cord injuries and other severely damaged tissues.
DALLAS - Sept. 15, 2020 - Conditions related to obesity, including inflammation and leaky gut, leave the lungs of obese patients more susceptible to COVID-19 and may explain why they are more likely to die from the disease, UTSW scientists say in a new article published online in eLife. They suggest that drugs used to lower inflammation in the lungs could prove beneficial to obese patients with the disease.
Researchers at the Norwegian University of Science and Technology (NTNU) have found a completely new method to check the electronic properties of oxide materials. This opens the door to even tinier components and perhaps more sustainable electronics.
"We found a completely new way to control the conductivity of materials at the nanoscale," says Professor Dennis Meier at NTNU's Department of Materials Science and Engineering.
"You have to eat!" It's a sentiment that illustrates how central food is to Italian culture, but the woman who uttered these words also happens to be struggling with bulimia nervosa.
Carmela* is one of many Italian-Australian women who has a conflicted relationship with food which is inextricably linked to culture, according to University of South Australia researcher Michelle Caruso.
The social work PhD student has undertaken the first study looking at how Italian culture can influence women's experiences of disordered eating in contemporary Australia.
Humans, like other animals, have the ability to constantly adapt to new situations. Researchers at the Brain Research Institute of the University of Zurich have utilized a mouse model to reveal which neurons in the brain are in command in guiding adaptive behavior. Their new study contributes to our understanding of decision-making processes in healthy and infirm people.
Researchers at the Western Pacific Tropical Research Center at the University of Guam have documented what biologists call a "host shift" of the coconut rhinoceros beetle in Guam. The beetle, first documented as an invasive species in Guam in 2007, has been devastating the island's ubiquitous coconut trees and is now also burrowing into Guam's endangered native cycad tree, Cycas micronesica. The results were published in June in Volume 13 of the Communicative & Integrative Biology journal.
Researchers have shown how industries could work together to recycle cigarette butts into bricks, in a step-by-step implementation plan for saving energy and solving a global littering problem.
Over 6 trillion cigarettes are produced each year globally, resulting in 1.2 million tonnes of toxic waste dumped into the environment.
Climatic conditions are changing at an unprecedented rate, affecting mainly fish, amphibians and reptiles, ectothermic animals that are unable to generate their own internal heat. With heat waves and rising temperatures, these organisms experience not only increased growth rates and heat stress, but also further ageing.
Using the X-ray laser European XFEL, a research team has investigated how water heats up under extreme conditions. In the process, the scientists were able to observe water that remained liquid even at temperatures of more than 170 degrees Celsius. The investigation revealed an anomalous dynamic behaviour of water under these conditions. The results of the study, which are published in the Proceedings of the National Academy of Sciences (PNAS), are of fundamental importance for the planning and analysis of investigations of sensitive samples using X-ray lasers.
These results from studies in both experimental and theoretical physics may help to improve antibacterial surfaces. The research work was recently published in the journal 'Nanoscale'.
PITTSBURGH, Sept. 16, 2020 - People with one of the most common heart disorders who are exposed to greater levels of pollution have a 1.2-fold higher risk of stroke than their peers who live with less pollution, according to a JAMA Network Open study published recently by researchers at the UPMC Heart and Vascular Institute and University of Pittsburgh School of Medicine.
Overall, scientists from 24 countries and regions contributed, including the United Kingdom, Saudi Arabia, the Netherlands, the United States, Greece, Germany, Brazil, Pakistan, Malaysia, Australia, Argentina, Georgia, Romania, Armenia, Chile, China (with Hong Kong as a separate participant), Turkey, Italy, and Mexico. Overall, 5,320 students have been polled. Associate Professor of the KFU's Department of Pedagogical Psychology Olga Lopukhova was one of the participants.
When we talk of Nordic history, it is all but impossible not to mention the Vikings. Stories about the Scandinavian warriors and their Old Norse Gods have long since travelled all around the world. But perhaps part of that narrative is only based on myths and brought to life by popular culture. At least, this is what is indicated by a new study from the University of Copenhagen.
Researchers at Trinity College Dublin have examined the sustainability of different models of the most commonly used oral health product - the toothbrush - to ascertain which is best for the planet and associated human health.
