| Posted: 06 Oct 2021 02:07 PM PDT A new study looks at the causal relationship between outdoor air pollution levels on nationwide university entry examination day and students' cognitive performance in Brazil. |
| Common diabetes drug promising against rare childhood brain tumor in laboratory studies Posted: 06 Oct 2021 01:00 PM PDT Metformin, a drug commonly prescribed against diabetes, holds promise against a rare type of childhood brain tumor in laboratory studies, an international team of researchers. |
| 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. |
| Neurobiologists identify widely used assembling and stabilizing forces behind brain synapses Posted: 06 Oct 2021 11:34 AM PDT Scientists provide promising new evidence that the 'planar cell polarity,' a powerful signaling pathway, is a widely used mechanism for the formation and maintenance of a large number of synapses. |
| 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. |
| 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. |
| 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. |
| 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. |
| ‘The mother of all cannabinoids’: Anti-seizure compounds discovered in cannabis Posted: 05 Oct 2021 07:19 AM PDT Scientists have found that three rare cannabinoids reduce seizures in mice. They using the information to develop a better cannabis-based treatment for Dravet syndrome, an intractable childhood epilepsy. |
| Posted: 05 Oct 2021 07:18 AM PDT Researchers have identified the mechanism that can lead to deafness in the rare syndrome, Norrie disease, which may lead to promising treatment targets for the incurable disease and other forms of profound hearing loss. |
| Posted: 04 Oct 2021 05:34 PM PDT A new study reveals differences in brain structure between antisocial and non-antisocial members of the same families which could explain why some show violent behavior whilst others do not. |
| Making self-driving cars human-friendly Posted: 04 Oct 2021 05:34 PM PDT Automated vehicles could be made more pedestrian-friendly thanks to new research which could help them predict when people will cross the road. Scientists investigating how to better understand human behavior in traffic say that neuroscientific theories of how the brain makes decisions can be used in automated vehicle technology to improve safety and make them more human-friendly. |
