Diagnostic blood test shows promise in early detection of Parkinson's

Early detection of Parkinson's could help doctors decide on treatment options or improve disease management. But often people get a neurological examination after symptoms appear, when vital brain cells have already been destroyed. Now a game-changing blood test is being developed to give doctors a reliable method to detect the disease earlier through clinical biomarkers.Read More

Prematurely born lambs kept alive in artificial external placenta – human babies could be next

When babies are born extremely premature – before 24 weeks of development in the womb – their lungs aren't strong enough to provide their organs with oxygen they need to develop properly. Nor are they strong enough to handle artificial ventilation. The result can mean a brief life for these tiniest of babies. A new artificial placenta that mimics conditions in the womb being developed by researchers at the University of Michigan might provide new hope.Read More

Screening existing drugs to uncover new weapons against antibiotic-resistant bacteria

Bacteria that are resistant to standard antibiotics represent one of the biggest threats to global health today, and one particular type, known as carbapenem-resistant Enterobacteriaceae (CRE), was recently classified by the US Centers for Disease Control and Prevention as having the most urgent antimicrobial resistance threat level possible. Help might just be at hand though, with researchers from the Beth Israel Deaconess Medical Center (BIDMC) using a screening method to identify existing drugs that might well prove effective against the dangerous bacteria.Read More

Discovery points to a reason for neuron death in stroke victims

It's well known that conditions such as schizophrenia, as well as strokes, seizures and traumatic brain injuries cause increased acidity around neurons in the brain, but scientists have struggled to understand exactly why this occurs. Now, researchers from the University at Buffalo may have pinpointed the reason, finding that an elusive receptor might play a big role.Read More

Portable device detects Ebola on the spot

It would definitely be an understatement to say that the sooner the Ebola virus is detected in blood samples, the better. Unfortunately, those samples currently have to be shipped off to labs for analysis, often far from the area being studied. That could soon change, though, as a compact new device can identify Ebola in under half an hour.Read More

Compound reverses symptoms of Alzheimer's and Parkinson's in fruit flies

Neurodegenerative disorders like Parkinson's and Alzheimer's are extremely widespread, affecting millions of people across the planet, but treatments are limited, and there's currently no cure available. New work is showing promise in the development of a new treatment, with scientists identifying a compound that can reverse symptoms of the diseases. The method hasn't been tested on human patients just yet, but it's been found to be effective in genetically modified fruit flies.Read More

Non-invasive treatment produces 98 percent prostate cancer cure rate

Traditional approaches to tackling prostate cancer are generally quite effective, with a 80 to 90 percent cure rate, but a new method, known as Stereotactic Body Radiation Therapy (SBRT) could revolutionize the practice. The results of an extensive five-year study have now been published, showing that the method, which requires far fewer hospital visits than conventional radiation therapy, has a cure rate of 98.6 percent.Read More

Smart scalpel knows the difference between healthy and tumorous tissue

For a brain surgeon, telling tumorous tissue from healthy tissue can be tricky business in the middle of a procedure, with potentially disastrous repercussions if mistakes are made. Looking to give these doctors a helping hand, scientists have designed a smart scalpel that provides real-time guidance on whether the tissue it is tending to is cancerous or otherwise.Read More
