Posted Yesterday Engineers at MIT and elsewhere have tracked the evolution of individual cells within an initially benign tumor, showing how the physical properties of those cells drive the tumor to become invasive, or metastatic. The team carried out experiments with a human breast cancer tumor that developed in the lab. As the tumor grew...

Pain relief: When to use cold, when to use heat
by Len Canter, Healthday Reporter (HealthDay)—Sore from a workout? You don’t have to reach for pain relief medicine when ice or heat will help. But when should you go cold and when should you go warm? Ice is the go-to therapy when an injury first happens. It can stop the swelling of a sprained ankle, for instance,...

New pain-blocking brain mechanism may relieve arthritis
Researchers have found that an experimental compound works in the amygdala to quell the pain of arthritis in rats. Experiments in rodents suggest that pain relief in arthritis originates in the brain. Pain is an alert that something is wrong — unfortunately, the pain does not go away while the problem remains, and finding a resolution is not...

New insights into how the brain perceives and processes odors
by Society for Neuroscience New research makes advances in understanding how smells are perceived and represented in the brain. The findings were presented at Neuroscience 2019, the annual meeting of the Society for Neuroscience and the world’s largest source of emerging news about brain science and health. Olfactory cues provide essential information for finding food, navigation, predator avoidance, and social...

In Alzheimer’s research, scientists reveal brain rhythm role
by Massachusetts Institute of Technology In the years since her lab discovered that exposing Alzheimer’s disease model mice to light flickering at the frequency of a key brain rhythm could stem the disorder’s pathology, MIT neuroscientist Li-Huei Tsai and her team at The Picower Institute for Learning and Memory have been working to understand what...

Q-suite motor assessment tool promising for evaluating Huntington’s disease
by IOS Press In clinical trials of adults with Huntington’s disease (HD) the Q-Suite Motor Assessment Tool (Q-Motor) has proven to be helpful to detect and quantitate subtle motor abnormalities. With the anticipated arrival of preventive gene therapies that will most likely be administered to young children known to be carriers of the HD mutation,...

A ‘shocking’ new way to treat infections
by Maggie Pavlick, University of Pittsburgh Titanium has many properties that make it a great choice for use in implants. Its low density, high stiffness, high biomechnanical strength-to-weight ratio, and corrosion resistance have led to its use in several types of implants, from dental to joints. However, a persistent problem plagues metal-based implants: the surface...

Neurotransmitters in an instant
INSTITUTE OF PHYSICAL CHEMISTRY OF THE POLISH ACADEMY OF SCIENCES Dopamine, serotonin, adrenalin… The smooth functioning of the human brain depends on their correct proportions. Any disturbances mean diseases. That’s why it’s so important to be able to detect these disturbances as early as possible – before the appearance of any visible symptoms. This will...

Polymerized estrogen shown to protect nervous system cells
Research could enable improved treatment of spinal cord injuries RENSSELAER POLYTECHNIC INSTITUTE TROY, N.Y. — Spinal cord damage that causes paralysis and reduced mobility doesn’t always stop with the initial trauma, but there are few treatment options to halt increased deterioration — and there is no cure. Researchers at Rensselaer Polytechnic Institute have developed a...
