| Massage doesn’t just make muscles feel better, it makes them heal faster and stronger Posted: 06 Oct 2021 11:34 AM PDT Massages feel good, but do they actually speed muscle recovery? Turns out, they do. Scientists applied precise, repeated forces to injured mouse leg muscles and found that they recovered stronger and faster than untreated muscles, likely because the compression squeezed inflammation-causing cells out of the muscle tissue. This work offers a non-invasive, drug-free treatment that can help regenerate many types of tissues, and confirms a functional link between mechanotherapy and immunotherapy. |

Researchers now show that these nano-bubbles can transport protein drugs that reduce inflammation caused by different diseases. The technique shows promising results in animal models. |
| Protecting the ozone layer is delivering vast health benefits Posted: 06 Oct 2021 10:49 AM PDT An international agreement to protect the ozone layer is expected to prevent 443 million cases of skin cancer and 63 million cataract cases for people born in the United States through the end of this century, according to new research. The research team developed a computer modeling approach that revealed the effect of the Montreal Protocol and subsequent amendments on stratospheric ozone, the associated reductions in ultraviolet radiation, and the resulting health benefits. |
| Sense of purpose associated with better memory Posted: 06 Oct 2021 10:49 AM PDT A new study showed a link between an individual's sense of purpose and their ability to recall vivid details. The researchers found that while both a sense of purpose and cognitive function made memories easier to recall, only a sense of purpose bestowed the benefits of vividness and coherence. |
| Cancer costs US more than $156 billion annually, with drugs a leading expense Posted: 06 Oct 2021 10:23 AM PDT Care for the 15 most prevalent types of cancer in the U.S. cost approximately $156.2 billion in 2018, according to a team researchers. The team also found that medication was the biggest expense and that medication expense for breast, lung, lymphoma and colorectal cancers incurred the most costs. |
| Of two common weight loss surgeries, one is safer but less effective Posted: 06 Oct 2021 10:23 AM PDT When comparing two of the most common weight loss surgeries, a research team found that long-term, sleeve gastrectomy is safer than gastric bypass for Medicare patients. |
| Weighing cancer cells to personalize drug choices Posted: 06 Oct 2021 08:27 AM PDT Researchers have developed a new way to determine whether individual patients will respond to a specific cancer drug or not. This kind of test could help doctors to choose alternative therapies for patients who don't respond to the therapies normally used to treat their cancer. |
| Brain cell differences could be key to learning in humans and AI Posted: 06 Oct 2021 08:26 AM PDT Researchers have found that variability between brain cells might speed up learning and improve the performance of the brain and future AI. |
| Toxic fatty acids to blame for brain cell death after injury Posted: 06 Oct 2021 08:26 AM PDT Cells that normally nourish healthy brain cells called neurons release toxic fatty acids after neurons are damaged, a new study in rodents shows. This phenomenon is likely the driving factor behind most, if not all, diseases that affect brain function, as well as the natural breakdown of brain cells seen in aging, researchers say. |
| Machine learning helps reveal cells’ inner structures in new detail Posted: 06 Oct 2021 08:26 AM PDT Scientists have created a set of tools to make annotated 3D images of cells, showing the relationships between different organelles. |
| Boosting the cell's power house Posted: 06 Oct 2021 08:26 AM PDT Severe fatigue, muscle weakness, even blindness -- mitochondrial diseases have various symptoms. In fact, the majority of genetic diseases are caused by defects of the mitochondria. Hence, understanding these 'power houses' of our cells is crucial for the developments of new treatments. Researchers now show the structure of a protein complex essential for their work. |
| Very potent antiviral against dengue Posted: 06 Oct 2021 08:26 AM PDT Researchers have developed an ultrapotent inhibitor of the dengue virus, which causes the tropical disease known as dengue. The antiviral molecule is exceptionally effective against all known dengue variants and could be used for therapeutic and prevention purposes. |
| Intelligence emerging from random polymer networks Posted: 06 Oct 2021 07:44 AM PDT A team of researchers assembled a sulfonated polyaniline (SPAN) organic electrochemical network device (OEND) for use in reservoir computing. SPAN was deposited on gold electrodes which formed a disordered network providing humidity-dependent electrical properties. The SPAN OEND was tested for reservoir computing using benchmark tasks and spoken-digit classification, which showed 70% accuracy. The device has the potential to be applied to a wide range of artificial intelligence tasks including speech recognition. |
| 'Living medicine' created to treat drug-resistant infections Posted: 06 Oct 2021 06:55 AM PDT Researchers have created 'living medicine' to treat antibiotic-resistant bacteria growing on the surfaces of medical implants. The researchers created the treatment by removing a common bacteria's ability to cause disease and repurposing it to attack harmful microbes instead. The findings are an important first step for the development of new treatments for these type of infections, which account for 80% of all infections acquired in hospital settings. |
| Years of exposure to air pollution and road traffic noise may raise heart failure risk Posted: 06 Oct 2021 05:05 AM PDT A study including more than 22,000 female nurses in Denmark evaluated exposure over 15-20 years to air pollution and road traffic noise to evaluate the impact on heart failure. Exposure to small particulate matter and road traffic noise over three years was associated with an increased risk for heart failure. The risks were greater among women who were former smokers or women who had high blood pressure. |
| Posted: 06 Oct 2021 05:05 AM PDT Allergic diseases such as asthma, atopic dermatitis and hay fever do not cause the onset of mental health conditions or vice versa, according to the new findings. |
