Today I'll point out a couple of recent research publications on the topic of the molecular mechanisms of exercise: how it might work to improve health, how it extends healthy life span but not maximum life span in animal studies, and how the response to exercise might be safely improved or otherwise manipulated.

Normal T-cell development requires Notch signaling but hyperactivity can lead to cancer. Drugs that inhibit Notch, such as gamma-secretase inhibitors, are currently being tested in different cancer types but clinical remission has yet to be reported. Show More Summary
Last week we launched the Fight Aging! fundraiser for SENS rejuvenation research programs, work on the biotechnologies needed to repair the cellular and molecular damage that causes aging and all age-related disease. Do we want to see meaningful progress towards the defeat of degenerative aging in our lifetime? Yes, yes we do. Show More Summary
New tools reveal details of the relationship between a ceramics’ molecular structure and its capacitance
How do we know that the melanosomes found in the fossils are actually melanosomes and not something else, like leftover impressions from the microbes (some of which also make melanin) that coated the feather during its decay and preservation?
The color of dinosaurs is a fascinating topic, and in recent years the discovery of melanosomes - small, pigment-filled sacs - associated with fossilized dinosaur feathers has given rise to all sorts of speculation about our prehistoric pals, from the hue of their plumage to color's impact on behavior. read more
What good stuff happens to your body, exactly, when you jump on that treadmill or bend into that downward dog for yoga?For decades, scientists have been emphasizing the importance of exercise for good health but how it works beyond the obvious benefits for weight loss and strengthening our hearts has been somewhat fuzzy.Read full article >>
NIBIB-funded researchers at the Massachusetts General Hospital have developed a smartphone-based device that can reliably carry out molecular diagnoses in under an hour for approximately two dollars per patient. The device could enable...Show More Summary
Physicists have developed a method to synthesize a unique and novel type of material which resembles a graphene nanoribbon but in molecular form. This material could be important for the further development of organic solar cells.
In a new review, researchers say that increased understanding of the molecular mechanisms by which exercise benefits health means an 'exercise pill' could soon be in the cards.
A molecular basis has been found for why 80 percent of patients with longstanding Type 1 diabetes have chronic gastrointestinal symptoms including gastroparesis (delayed emptying of food), irritable bowel syndrome, abdominal distension and fecal incontinence, significantly reducing their quality of life.
These days its hard to tell science and science fiction apart -- we're gardening in space, cars are driving themselves, and invisibility cloaks are real (at least, at the molecular level). If you're having trouble telling fact from fiction,...Show More Summary
Scientists have gained new insight into the formation of the spindle, which is the molecular machine that divides up genetic material prior to cell division. Their work focuses on the motor protein kinesin-5, which helps to organize the spindle's filaments.
Jet airplanes load up with tens of thousands of gallons of fuel for transcontinental flights, which can lead to massive explosions in a crash or terrorist attack. But adding “molecular velcro” to fuel can dramatically reduce its volatility, or explosiveness. Read more...
When a pathogen invades the body, specific cells in the human immune system are ready to take immediate action in order to destroy it. The molecular characteristics of these killer cells were unknown until recently. Now, for the first time, a team of researchers has managed to create a molecular profile of the protective cells.

New fossil evidence suggests human ancestors may have split from chimps as early as 10 million years ago, bringing fossil evidence in line with data from molecular clocks
Research finds around 1000 molecular reactions to exercise, opening the door for drug treatments to mirror the health benefits of exercise.
Circadian rhythms help everything from plants to humans coordinate with the daily light-dark cycle, but how this natural clock keeps accurate time, or why it goes awry in people with sleep disorders, is still under investigation. New...Show More Summary
When cells from the connective tissue collide, they repel one another -- this phenomenon was discovered more than 50 years ago. It is only now, however, that researchers have discovered the molecular basis for this process. Their findings could have important implications for cancer research.
Clinical use of next generation sequencing (NGS) was implemented early in cancers and inherited diseases; now, its technology and applications are being applied to infectious diseases.
