Childhood environment and socioeconomic status affect cognitive ability and brain development during adolescence independently of genetic factors, researchers at Karolinska Institutet report in a new study published in the journal PNAS. The study demonstrates how important the family environment is, not just during early infancy but also throughout adolescence. While […]

Scientific research has changed dramatically in the centuries since Galileo, Newton and Darwin. Whereas scientists once often toiled in isolation with homemade experiments and treatises, today collaboration is the norm. Teams of scientists now routinely pool and process reams of data gleaned from high-tech instruments. Yet as modern science has […]

For decades, scientists have explored the use of liposomes –– hollow spheres made of lipid bilayers –– to deliver chemotherapy drugs to tumor cells. But drugs can sometimes leak out of liposomes before they reach their destination, reducing the dose received by the tumor and causing side effects in healthy […]

Study Suggests Potential Anti-Inflammatory Properties of Ketone Bodies Via Effects on Gut Microbial Ecosystems. Low-carb, high-fat ketogenic diets, which have attracted public interest in recent years for their proposed benefits in lowering inflammation and promoting weight loss and heart health, have a dramatic impact on the microbes residing in the […]

In the largest study of its kind, researchers have confirmed a new non-invasive test can be used to help with the early detection of endometrial cancer and at-risk patients.

Researchers examine proteins to identify what is 'broken' in tumor cells The rogue cellular engine that drives a majority of ovarian cancers remains frustratingly difficult to disable. A new study comparing cancerous tissue with normal fallopian tube samples advances important insights about this machinery and confirms biological hallmarks of survival. High-grade […]

Recent large scale efforts to categorize the molecular data of multiple cancer types has yielded so much information that researchers now have a new question: How to turn all this data into meaningful information that guides cancer research and patient care. A new analytic tool developed by the University of […]

MIT neuroscientists have discovered that an enzyme called HDAC1 is critical for repairing age-related DNA damage to genes involved in memory and other cognitive functions. This enzyme is often diminished in both Alzheimer’s patients and normally aging adults. In a study of mice, the researchers showed that when HDAC1 is […]

This open access paper provides a good high-level overview of what is known of the molecular mechanisms underpinning the beneficial response to calorie restriction and intermittent fasting. In short-lived species, quite sizable gains in life span are possible, though this is not the case for longer-lived species such as our own. The metabolic responses to […]

Nutraceuticals are compounds derived from foods, usually plants. In principle one can find useful therapies in the natural world, taking the approach of identifying interesting molecules and refining them to a greater potency than naturally occurs in order to produce a usefully large therapeutic effect. Unfortunately, in practice the nutraceutical industry […]

As people get older, they often feel less energetic, mobile or active. This may be due in part to a decline in mitochondria, the tiny powerhouses inside of our cells, which provide energy and regulate metabolism. In fact, mitochondria decline with age not only in humans, but in many species. […]

Researchers from Sechenov University (a Project 5-100 participant) and University of Pittsburgh (USA) discovered that the resistance of innate immune cells, macrophages, to ferroptosis – a type of programmed cell death – depends on the type of their activation. It turned out that cells helping tissues to recover from inflammation […]
