Complex data workflows contribute to reproducibility crisis in science, Stanford scientists say

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 […]

Nanobowls serve up chemotherapy drugs to cancer cells

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 finds that aging neurons accumulate DNA damage

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 […]

Mechanisms of Calorie Restriction and Intermittent Fasting

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 […]

On Nutraceutical Senolytics

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 […]

Subcellular chatter regulates longevity

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. […]

‘Cells-Soldiers’ Turned to Be More Resistant Than ‘Cells Combat-Medics’

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 […]

Breakthrough to halt premature aging of cells

Study identifies potential drug treatments for telomere diseases. Capping decades of research, a new study may offer a breakthrough in treating dyskeratosis congenita and other so-called telomere diseases, in which cells age prematurely. Using cells donated by patients with the disease, researchers at the Dana-Farber/Boston Children’s Cancer and Blood Disorders Center identified several […]

Neural Logic

Julie H. Simpson receives an NSF CAREER award to study how neural circuits coordinate behaviors. Everything we do comes down to a series of neural signals that translate into physical behaviors. We receive information through our senses, sensory neurons convert this information into electrical and chemical signals that are processed […]

Gut Ecology

Researchers use old equations coupled with new methods to help decode the massively complex gut microbiome. For something that has evolved with us over millions of years, and remains part of our physiology over our entire lives, our gut microbiome, oddly, remains somewhat of a mystery. Comprised of trillions of […]

Mother roundworms have ultra-protective instincts

Talk about motherly instincts: Biologists at the University of Iowa have learned that female roundworms can alert their future offspring of dangers they will encounter when born, and the mothers pass on these warnings even before the offspring have been conceived. The study shows that a mother roundworm releases a chemical […]
