The causes of 40% of all cases of certain medulloblastomas -- dangerous brain tumors affecting children -- are hereditary. A genetic defect that occurs in 15% of these children plays a key role by destabilizing the production of proteins. The researchers suspect that protein metabolism defects could be a previously underestimated cause of other types of cancer.

The bacteria that cause tuberculosis need iron to survive. Researchers have now solved the first detailed structure of the transport protein responsible for the iron supply. When the iron transport into the bacteria is inhibited, the pathogen can no longer grow. This opens novel ways to develop targeted tuberculosis drugs.

MIT engineers are working on developing soft, flexible neural implants that can gently conform to the brain's contours and monitor activity over longer periods, without aggravating surrounding tissue. Such flexible electronics could be softer alternatives to existing metal-based electrodes designed to monitor brain activity, and may also be useful in brain implants that stimulate neural regions to ease symptoms of epilepsy, Parkinson's disease, and severe depression.

Researchers have discovered a way to refine the production of retinal cells from embryonic stem cells for treating blindness in the elderly. Using the CRISPR/Cas9 gene editing, they have also managed to modify the cells so that they can hide from the immune system to prevent rejection.

Researchers describe their discovery of a new mechanism that could contribute to the pathogenesis of inflammatory diseases. The scientists found that ZBP1, a protein best known for defending against incoming viruses, is activated by sensing an unusual form of cellular genetic material (Z-nucleic acids), leading to cell death and inflammation.

When discussions occur face-to-face, people know where their conversational partner is looking and vice versa. With ''virtual'' communication due to COVID-19 and the expansive use of mobile and video devices, now more than ever, it's important to understand how these technologies impact communication. Where do people focus their attention? The eyes, mouth, the whole face? And how do they encode conversation? A first-of-its-kind study set out to determine whether being observed affects people's behavior during online communication.

Scientists have recently released guidance for prevention and management of COVID-19 among elderly in long term care facilities. The article outlines the objective of WHO interim guidance on Infection Prevention and Control (IPC) in Long-Term Care Facilities (LTCF) in the context of COVID-19 which is to prevent COVID-19-virus from entering the facility, spreading within the facility, and spreading to outside the facility.

People continuously exposed to air pollution are at increased risk of dementia, especially if they also suffer from cardiovascular diseases, according to a new study. Therefore, patients with cardiovascular diseases who live in polluted environments may require additional support from care providers to prevent dementia, according to the researchers.

In Kuwait, a country known for hot weather, death certificates reveal that on days when the temperatures reached extremes of an average daily temperature of 109 degrees Fahrenheit, the number of deaths from cardiovascular disease dramatically increased. With unprecedentedly high temperatures, people living in inherently hot regions of the world may be at particularly high risk of heat-related cardiovascular death.

There's a price to pay when you get your news and political information from the same place you find funny memes and cat pictures, new research suggests. The study found that people viewing a blend of news and entertainment on a social media site tended to pay less attention to the source of content they consumed - meaning they could easily mistake satire or fiction for real news.

Scientists have identified a new control mechanism that enables stem cells to adapt their activity in emergency situations. For this purpose, the stem cells simultaneously modify the blueprints for hundreds of proteins encoded in the gene transcripts. In this way, they control the amount of protein produced and can also control the formation of certain proteinisoforms. If this mechanism is inactivated, stem cells lose their self-renewal potential and can no longer react adequately to danger signals or inflammation.
