Creating custom brains from the ground up

Scientists studying how genetics impact brain disease have long sought a better experimental model. Cultures of genetically-modified cell lines can reveal some clues to how certain genes influence the development of psychiatric disorders and brain cancers. But such models cannot offer the true-to-form look at brain function that can be provided by genetically-modified mice. Even […]

Stroke care gains in Puerto Rico falter after Hurricane Maria

A project aimed at improving the inequalities in stroke care between Puerto Rico and the mainland did just that—until Hurricane Maria roared ashore last September and further hobbled the territory’s already inadequate health care system, experts say. Researchers at the University of Miami started the Florida-Puerto Rico Collaboration to Reduce Stroke Disparities knowing stroke patients […]

Treating mental disorders with psychedelic psychotherapy

Millions of Australians suffer from a myriad of mental health issues. Depression, PTSD and addiction to name a few. But what if we could help them by trying something a little trippy? Every day in Australia, more than eight people die by suicide. Millions more suffer mental health issues. We have treatments available, but in […]

Rheumatoid arthritis sufferers can now live a

MedUni Vienna researchers Daniel Aletaha and Josef Smolen have published a review on the status of rheumatoid arthritis in JAMA to coincide with World Arthritis Day on 12 October. The main positive finding: in recent years there has been a significant improvement in outcomes for sufferers. “Eighty percent of sufferers can lead a normal life […]

Supercharged natural killer cells may hold promise for cancer

A type of ‘supercharged’ immune cell could be mass-produced to help fight cancer. The researchers behind the early-stage finding, from Imperial College London, say the development could mark the next generation of cutting-edge immunotherapy treatments, called CAR-T therapies. These personalised treatments involve reprogramming immune cells to kill cancer. NHS England announced on Friday it would […]

Recovering from a heart attack? Hold the antibiotics

The community of microorganisms that live in the human gut has been shown to confer all kinds of health benefits. Now, an international team of researchers has shown in mice that a healthy gut microbiome is important for recovery after a heart attack. Writing today (Oct. 8, 2018) in the journal Circulation, a team led […]

Half the brain encodes both arm movements

Individual arm movements are represented by neural activity in both the left and right hemispheres of the brain, according to a study of epilepsy patients published in JNeurosci. This finding suggests the unaffected hemisphere in stroke could be harnessed to restore limb function on the same side of the body by controlling a brain-computer interface. […]

Physiologist publishes findings on the role of the protein titin in muscle contraction

In the field of muscle physiology, scientists study muscle movement at the molecular level—chiefly, proteins such as myosin, actin and titin—to understand how muscles contract. Their research improves human health and quality of life in a wide range of areas, including rehabilitation engineering, prosthesis design and the treatment of neuromuscular diseases such as muscular dystrophy, […]

How the brain learns during sleep

Researchers from Ruhr-Universität Bochum and the University of Bonn have investigated which activity patterns occur in the brain when people remember or forget things. They were interested in how the brain replays and stores during sleep what it had learned before. The team recorded the brain activity of epilepsy patients who had electrodes implanted into […]
