Scientists reliably predict people’s age by measuring proteins in blood

The carnival worker who tries to guess your age relies on aspects of your appearance, such as your posture and whether any wrinkles emanate from the corners of your eyes and lips. If the carny’s guess is more than a few years off, you win a stuffed koala. But a team of Stanford University School of Medicine scientists doesn’t need […]

Measurement of uterine contractions could predict the outcome of in vitro fertilization

In vitro fertilization (IVF) is considered as the gold standard of assisted reproductive technologies. Yet, the failure rate for IVF treatments is still above 70 percent, and the exact causes of failure remain unknown. Federica Sammali, Ph.D. candidate at the department of Electrical Engineering, has developed a system for measuring and characterizing uterine contractions, which are known to influence the […]

A machine learning-based algorithm to predict which cancer patients benefit from immunotherapy

Scientists at the Institute for Research in Biomedicine (IRB Barcelona), in collaboration with the Centre for Genomic Regulation (CRG) and Radboud University, have developed an algorithm that can predict which cancer patients are more likely to benefit from immunotherapy. Mutations in our DNA can disrupt protein synthesis, sometimes causing truncated proteins which don’t work as intended. Known as nonsense mutations, […]

Looking at the way we walk can help predict cognitive decline

The way people walk is an indicator of how much their brains, as well as their bodies, are aging. Scientists reporting in a special supplement to the Journal of Alzheimer’s Disease (JAD) say that gait disorders, particularly slowing gait, should be considered a marker of future cognitive decline. They propose testing motor performance as well as cognitive performance in older […]

Your personality as a teen may predict your risk of dementia

(HealthDay)—Could your personality as a teen forecast your risk for dementia a half-century later? Very possibly, say researchers, who found that dementia risk is lower among seniors who were calm, mature and energetic high schoolers. “Being calm and mature as teen were each associated with roughly a 10% reduction in adult dementia risk,” said study co-author Kelly Peters, principal researcher […]

Scientists predict the areas of the brain to stimulate transitions between different brain states

A fundamental question in neuroscience is how to force the transition from one brain state to another, for example, from sleep to wakefulness, or in the face of brain pathologies, such as psychiatric diseases and impaired consciousness. As Gustavo Deco and Josephine Cruzat point out: “it is feasible to force the transition from one brain state to another by means […]

Sports playbook helps doctors predict cancer patient outcomes

In this season of global soccer competitions and hotly contested political primaries, bookies and pundits are scouring every evolving scrap of information and sifting through mountains of data in an effort to predict the outcome of the next game or election. These predictions can change on a dime, however, based on a player’s poor pass or a candidate’s stellar debate […]

Gene levels could help predict prognosis for colorectal cancer

Levels of a gene that helps the immune system differentiate the good cells from the bad could be a good indicator of prognosis in people with colorectal cancers, Medical College of Georgia researchers report. Looking at 15 genes known to be associated with colorectal cancers—eight associated with lower survival rates and seven with higher—the researchers found that one gene, CCR4, […]

Ability to do pushups may predict cardiovascular risk

World Health Organization (WHO) data indicate that every year there are 17.9 million deaths due to cardiovascular diseases (CVDs), accounting for approximately 31 percent of global deaths. Many of the factors that increase the risk of CVD are modifiable, chiefly an unhealthful diet, a lack of physical activity, smoking, or frequent consumption of alcohol. The link between exercise — particularly […]
