| Closer to gene therapy that would restore hearing for the congenitally deaf Posted: 19 May 2021 05:04 AM PDT Researchers have found a key new piece of the puzzle in the quest to use gene therapy to enable people born deaf to hear. |
| What happens in the brain when we imagine the future? Posted: 18 May 2021 05:54 PM PDT What happens in the brain when people think about the future? Neuroscientist find that two sub-networks play a role. One focuses on creating the new event. Another evaluates whether that event is positive or negative. |
| A new theory for what's happening in the brain when something looks familiar Posted: 18 May 2021 05:54 PM PDT Neuroscientists present a new theory for what's happening in the brain when something looks familiar. The work brings the field one step closer to understanding how memory functions. Long-term, it could have implications for treating diseases like Alzheimer's. |
| A gentler strategy for avoiding childhood dental decay Posted: 18 May 2021 05:54 PM PDT By targeting the bonds between bacteria and yeast that can form a sticky dental plaque, a new therapeutic strategy could help wash away the build-up while sparing oral tissues, according to a new study. |
| Test detects childhood tuberculosis a year ahead Posted: 18 May 2021 08:48 AM PDT Researchers have developed a highly sensitive blood test that can find traces of the bacteria that causes tuberculosis (TB) in infants a year before they develop the deadly disease, according to a new study. |
| Embryo cryopreservation minimizes cryoinjuries, offers hope for would-be parents Posted: 18 May 2021 08:48 AM PDT Not all embryo transfers succeed, which gives rise to the practice of freezing extra embryos from an IVF cycle for future transfers. This allows those with at-risk fertility, due to age or treatments such as chemotherapy, to delay their transfer. Researchers introduce a standalone microfluidics system to automate the process of embryo vitrification of replacing water with cryoprotectants, which exposes embryos to a slow and constantly increasing concentration of cryoprotectants. |
| Adding antibodies to enhance photodynamic therapy for viral and bacterial disease Posted: 18 May 2021 08:48 AM PDT Photodynamic therapy, or using light to inactivate viruses, bacteria, and other microbes, has garnered promising results in recent decades for treating respiratory tract infections and some types of cancer. Researchers review the existing approaches and propose adding antibodies to enhance PDT efficacy. They provide a model to help expedite overall PDT development as a rapid response to emergent viral pandemic threats. |
| Synaptic transmission: Not a one-way street Posted: 18 May 2021 08:44 AM PDT When neuroscientists analyzed the exact properties of nerve connections in the brain, they made a startling observation: At a key connection, or synapse, messages are sent against the usual stream of information. The study reports that the signal glutamate likely plays a role in this unusual transmission. |
| Mathematical model predicts effect of bacterial mutations on antibiotic success Posted: 18 May 2021 08:41 AM PDT Scientists have developed a mathematical model that predicts how the number and effects of bacterial mutations leading to drug resistance will influence the success of antibiotic treatments. |
| Scientists map gene changes underlying brain and cognitive decline in aging Posted: 18 May 2021 08:41 AM PDT Alzheimer's disease shares some key similarities with healthy aging, according to a new mathematical model. |
| Linguistic and biological diversity linked Posted: 17 May 2021 04:47 PM PDT Cultural diversity -- indicated by linguistic diversity -- and biodiversity are linked, and their connection may be another way to preserve both natural environments and Indigenous populations in Africa and perhaps worldwide, according to an international team of researchers. |
