Under-skin implant reverses type 1 diabetes without anti-rejection drugs
December 05, 2023Researchers developed a technique to implant a device containing insulin-secreting cells in a pocket under the skin, reversing diabetes in mice without the need for anti-rejection drugs. It could one day provide an alternative to insulin injections. -
Once-a-day pill for stubborn cancer delivers a 62.5% positive response
December 05, 2023In what has already been tagged as a “game-changer” for cancer treatment, the potent once-a-day tablet known as divarasib has continued to impress at Phase 1b trial stage, outperforming not just current therapies but its previous trial results. -
Stem cell breakthrough may mean better treatment for Parkinson’s disease
December 05, 2023Researchers have genetically engineered stem cells to transform into greater numbers of the neurons needed for effective Parkinson’s disease cell therapy. The method could be used to generate other types of brain cells to treat a range of disorders. -
Twice-daily brain zaps may boost 'rewiring' & functioning in Alzheimer’s
December 05, 2023Research has found that non-invasively applying a mild electrical current to the brain twice a day for six weeks improved cognitive functioning and plasticity, the ability of the brain to ‘rewire’ itself, in patients with Alzheimer’s disease. -
Regular ketamine use found to restructure the brain's dopamine system
December 04, 2023Researchers have revealed how regular ketamine use produces divergent changes in parts of the brain that produce the ‘feel-good’ neurotransmitter, dopamine. The discovery could have significant implications for the treatment of mental illness. -
In a first, human study shows how dopamine teaches our brain new tricks
December 04, 2023A groundbreaking study has mapped dopamine, deep inside the brain, in real time. Surprising researchers, the "pleasure neurotransmitter" is more complex than earlier thought, shaping our brain to make better decisions based on prior experience. -
High altitude 'prehab' may reduce surgical complications in older patients
December 03, 2023A study has found that placing older adults in a simulated high-altitude environment for a week before major surgery greatly improved their hemoglobin levels, addressing a common preoperative problem, anemia, that can lead to surgical complications. -
Immunotherapy strategy offers hope to autoimmune skin disease sufferers
December 03, 2023Researchers have identified a way of selectively eliminating the ‘bad’ immune cells that contribute to autoimmune skin diseases like psoriasis while leaving the ‘good’ cells intact. The discovery could lead to longer-lasting, more targeted treatments. -
The humble bean arms the gut with surprise cancer-fighting powers
December 03, 2023Beans don't have the best rep when it comes to our guts. But a new study has shown how a daily dose of navy beans can easily restore gut health in colorectal cancer survivors, revealing their broad benefit in helping protect against chronic diseases. -
Tiny biobots made from human cells promote neuron growth without DNA mods
November 30, 2023Researchers have used human cells to create tiny biobots that can encourage healing in damaged neurons without requiring genetic modifications. The tiny bots have the potential to transform regenerative medicine and the treatment of disease. -
At-home saliva testing could replace daily finger-jabs for diabetics
November 30, 2023Daily finger-prick blood tests are an uncomfortable fact of life for diabetics, but they may not always have to be. Scientists from Canada and the US have developed a prototype home-use device that measures blood glucose levels via saliva samples. -
Brain cell gene changes linked to neuroinflammation seen in Alzheimer’s
November 29, 2023Research has revealed how genetic changes in a specialized population of brain cells called microglia contribute to neuroinflammation and, in turn, to Alzheimer’s disease. The findings could lead to more effective, targeted therapeutics. -
Eye-safe laser device provides rapid, on-site diagnosis of concussion
November 29, 2023Researchers have developed a handheld device that shines a safe laser into the eye to detect biomarkers of brain damage following a concussion or other traumatic brain injury, providing rapid, on-site diagnosis at the time of injury. -
Fatty acid in beef & dairy found to boost immune cells’ cancer response
November 28, 2023A study has found that a fatty acid found in meat and dairy may boost the cancer-killing abilities of the immune system’s T cells. Also found to enhance the effectiveness of immunotherapy, the nutrient could be used to complement cancer treatments. -
Harvard scientists identify link between pain and poor sleep
November 28, 2023Most of us have woken up with an aching back after a sleepless night, only for that pain to then keep us awake the next night. Now Harvard scientists have discovered a possible link between pain and poor sleep, and maybe even a way to break the loop.
