| Posted: 21 Mar 2022 07:38 AM PDT Lifelong physical activity could protect against age-related loss of muscle mass and function, according to new research. Individuals aged 68 and above who were physically active throughout their life have healthier aging muscle that has superior function and is more resistant to fatigue compared to inactive individuals, both young and old. This is the first study to investigate muscle, stem cell and nerve activity in humans. The researchers from University of Copenhagen, Denmark, found that elderly individuals who keep physically active throughout their adult life, whether by taking part in resistance exercise, ball games, racket sports, swimming, cycling, running and/or rowing had a greater number of muscle stem cells, otherwise known as satellite cells in their muscle. These cells are important for muscle regeneration and long-term growth and protect against nerve decay. |
| Bacteria-shredding insect wings inspire new antibacterial packaging Posted: 21 Mar 2022 07:38 AM PDT Inspired by the bacteria-killing wings of insects like cicadas, scientists have developed a natural antibacterial texture for use on food packaging to improve shelf life and reduce waste. |
| Study shows that intranasal Rx halts memory decay in experimental Alzheimer’s model Posted: 21 Mar 2022 07:38 AM PDT A research collaboration has found that applying specialized pro-resolving lipid mediators intranasally arrested memory loss and brain degeneration in an experimental model of Alzheimer's Disease (AD). |
| Characterizing super-semi sandwiches for quantum computing Posted: 21 Mar 2022 07:38 AM PDT Semiconductors are the foundation of modern technology while superconductors with their zero electrical resistance could become the basis for future technologies, including quantum computers. So-called 'hybrid structures' -- carefully crafted sandwiches made from superconductors and semiconductors -- may lead to new quantum effects. However, convincing observations have remained elusive. Now, researchers have found a way to probe such 'super-semi sandwiches' and to reveal what is going on. |
| Booster for immune protection after coronavirus infection Posted: 21 Mar 2022 07:37 AM PDT When our immune system comes into contact with the SARS-CoV-2 coronavirus, it fights back and produces antibodies. A similar immune response is triggered by coronavirus vaccines. However, there is still little data available on the strength and durability of immune protection. Researchers have now been able to detect high levels of neutralizing antibodies in test persons even 300 days after a coronavirus infection with the original variant of the coronavirus. |
| COVID-19 pandemic fueled massive growth in green industry Posted: 21 Mar 2022 07:37 AM PDT The COVID-19 pandemic hasn't been a great couple of years. But for the green industry, like plant nurseries and greenhouses, it's been a boon. But will the uptick in gardening last once the last coronavirus restrictions are lifted? Probably not to the same extreme levels, according to new research. But for some, the introduction to gardening may have been just what they needed to dive into a new hobby. |
| A novel painless and reliable allergy test Posted: 21 Mar 2022 07:37 AM PDT Although allergies are widespread, their diagnosis is complex and, depending on the type of allergy, the prospects of success with therapy are not always clear. Skin tests so far have been unpleasant, time-consuming and associated with a certain risk of triggering an allergic overreaction. Researchers have now developed a novel test that massively simplifies the diagnosis of allergies and can reliably predict the success of a therapy. |
| Soil erosion and wildfire another nail in coffin for Triassic era Posted: 21 Mar 2022 07:37 AM PDT New research has revealed that soil erosion and wildfires contributed to a mass extinction event 201 million years ago that ended the Triassic era and paved the way for the rise of dinosaurs in the Jurassic period. |
| New ways to improve urban wetlands Posted: 21 Mar 2022 06:19 AM PDT New studies provide valuable insights into removing toxins from polluted waterways and improving filtration at urban wetlands. One study found a wetland plant capable of reducing PFAS in soil and water, and another looked for better urban wetland water flow management during summer. |
| MRI innovation makes cancerous tissue light up and easier to see Posted: 21 Mar 2022 06:19 AM PDT A new form of magnetic resonance imaging (MRI) that makes cancerous tissue glow in medical images could help doctors more accurately detect and track the progression of cancer over time. |
