Nailing digital fakes with AI-learned artifacts

We see the imaginative feats of photo fakery; now we have to figure out what to do about them. Being able to tell fake from real is the goal, but how to get there? Forensics is the key tool to hunt down fake photos and it does not appear to be an easy task in getting that tool to perform well.

Combination of three gene mutations results in deadly human heart disease

Congenital heart disease occurs in up to 1% of live births, and the infants who are affected may require multiple surgeries, life-long medication, or heart transplants. In many patients, the exact cause of congenital heart disease is unknown. While it is becoming increasingly clear that these heart defects can be caused by genetic mutations, it is not well understood which genes are involved and how they interact. Genetic mutations, also called genetic variants, can also cause poor heart function, but the type and severity of dysfunction varies widely even among those with the same mutation.

Understanding why virus can't replicate in human cells could improve vaccines

The identification of a gene that helps to restrict the host range of the modified vaccinia virus Ankara (MVA) could lead to the development of new and improved vaccines against diverse infectious agents, according to a study published May 30 in the open-access journal PLOS Pathogens by Bernard Moss of the National Institutes of Health, and colleagues.

Exposure to airborne metal pollution associated with increased risk of mortality

Although there is ample evidence that air pollution—specifically airborne particulate matter—is associated with an increased risk of premature death, it is still not known which specific particles are responsible for this effect. The Barcelona Institute for Global Health (ISGlobal), a research centre supported by "la Caixa," participated in a study that used wild moss samples to estimate human exposure to airborne metal particles in order to analyse the relationship between atmospheric metal pollution and risk of mortality.

Researchers discover a new way to protect against high-dose radiation damage

Radiotherapy is one of the most effective ways to destroy cancer cells and shrink tumors. Around 50 percent of patients with tumors located in the gastrointestinal cavity (liver, pancreas, colon, prostate, etc) receive this type of treatment, which has increased cancer survival rates in recent decades. However, intensive radiation therapy not only damages tumor cells, but also healthy intestinal cells, leading to toxicity in 60 percent of treated patients. Whereas reversal of toxicity is observed after radiotherapy has concluded, 10 percent of treated patients develop gastrointestinal syndrome, a disease characterized by intestinal cell death, resulting in the destruction of the entire intestine and patient death.
