Research team identifies potential target protein aggregates for treating Alzheimer's disease

The aggregation of alpha-synuclein proteins in Parkinson's disease and tau proteins in Alzheimer's disease is intimately linked to the progression of these neurodegenerative diseases. These aggregates propagate from one neuronal cell to another, attaching themselves to the cells.

Study finds specific mechanism that protects cells from natural DNA errors

Researchers from the University of Copenhagen have identified a specific mechanism that protects our cells from natural DNA errors - an 'enemy within' - which could permanently damage our genetic code and lead to diseases such as cancer.

New device allows scientists to reproduce blow effects on the heart in lab

A blow to the chest can have highly contrasting effects. For instance, some baseball players have died after being hit in the chest by a baseball, while patients undergoing fatal cardiac tachyarrhythmias have been saved by an appropriately timed thump to the chest.

Researchers understand cues controlling collective cell migration during development

Collective cell migration, where groups of cells move together with a common purpose, is important for processes ranging from wound healing to tumor metastasis.

Study shows that even moderate alcohol consumption may increase risk of atrial fibrillation

Alcohol is ubiquitous in Western society, and rates of excessive use among adults remain high. Excessive alcohol consumption is an established risk factor for atrial fibrillation, but what are the effects of moderate and mild consumption on AF?

Researchers reveal cause of possible genetic problems in mitochondria

A group of researchers from the Andalusian Centre for Molecular Biology and Regenerative Medicine has revealed the importance of eliminating any excess of defective products that might have accumulated in the mitochondria, as its presence generates mitochondrial instability and information loss on the mitochondrial genome.

Novel sensor monitors beating heart cells with minimal disruption

For the first time, engineers have demonstrated an electronic device to closely monitor beating heart cells without affecting their behavior. A collaboration between the University of Tokyo, Tokyo Women's Medical University and RIKEN in Japan produced a functional sample of heart cells with a soft nanomesh sensor in direct contact with the tissue.

New study uses intracranial recordings to investigate memory development

Declarative memory -- memories that can be consciously recalled -- is critical to everyday life. Throughout childhood and adolescence, declarative memory improves remarkably. However, until most recently, there was a critical gap in our understanding of how maturation of the prefrontal cortex drives memory development.

Researchers develop new system for efficiently producing human norovirus

An Osaka University-led research team has developed a system for simply and efficiently producing human norovirus. By coaxing human induced pluripotent stem cells to develop into a type of cell that usually lines the intestine, they created a cellular environment that can be used for producing the virus, studying how it interacts with human cells, and investigating potential vaccines.

Scientists use hair-thin fiber endoscope to gain insights into hardly-accessible brain structures

It is the first time, scientists are able to achieve high-resolution observations of neuronal structures inside deep brain areas of living mice - by the use of the most minimally invasive endoscopic probe reported thus far.

Study: Vegetables and salad may include bacteria that are resistant to antibiotics

Salad is popular with people who want to maintain a balanced and healthy diet. Salad varieties are often offered for sale ready-cut and film-packaged. It is known that these types of fresh produce may be contaminated with bacteria that are relevant from the point of view of hygiene.

New study upends conventional theories about fluid nature of cell membranes

If you want to understand how the cell membrane works, Adam Cohen says, look no further than your kitchen. Cohen, a Professor of Chemistry and Chemical Biology and of Physics, is the lead author of a new study that upends the conventional theories about the fluid nature of cell membranes and how they react to tension.

Exposure to transportation noise and air pollution raises heart attack risk

Where air pollution is high, the level of transportation noise is usually also elevated. Not only air pollution negatively impacts on health, but also car, train and aircraft noise increases the risk for cardiovascular diseases and diabetes, as previous research has demonstrated.

Top journal publishes special issue on deep learning for drug discovery and biomarker development

While the many concepts in artificial intelligence date back to the 20th century, the revolution in deep learning started around 2014-2015 when AI systems started outperforming humans in many tasks ranging from video games and image recognition to autonomous driving.

Daily exercise facilitates elimination of toxic proteins from muscles

A study published in Scientific Reports by researchers at the University of São Paulo in Brazil, in partnership with colleagues in the United States and Norway, shows that the lack of muscle stimulus results in a buildup of inadequately processed proteins in muscle cells and consequently leads to muscle weakness or wasting.
