Regular bicycling is a great way to loose weight and improve your physical fitness. A 150-pound person burns 410 calories while pedaling 12 miles in an hour. A 200-pound cyclist burns 546 calories while going 12 miles in an hour.

    • Industrial cleaner linked to increased risk of Parkinson's disease
      Workers exposed to tricholorethylene, a chemical once widely used to clean metal such as auto parts, may be at a significantly higher risk of developing Parkinson's disease, according to a new study.
    • 'Starving' fat suppresses appetite
      Peptides that target blood vessels in fat and cause them to go into programmed cell death (termed apoptosis) could become a model for future weight-loss therapies, say researchers.
    • Older female cancer survivors have added health issues compared to their counterparts
      As cancer survivors live longer, questions arise about what kind of care long-term survivors require. A recently study found 245 older married women who survived cancer had more health problems as compared to a sample of 245 married women without cancer.
    • Argonautes: A big turn-off for proteins
      Scientists believe they may have figured out how genetic snippets called microRNAs are able to shut down the production of some proteins.
    • Scientists identify first genetic variant linked to biological aging in humans
      Scientists announced they have identified for the first time definitive variants associated with biological ageing in humans. The new discovery has important implications for the understanding of cancer and age-associated diseases.
    • Transforming human fat into stem cells using virus-free technique
      Tiny circles of DNA are the key to a new and easier way to transform stem cells from human fat into induced pluripotent stem cells for use in regenerative medicine, say scientists. Unlike other commonly used techniques, the method, which is based on standard molecular biology practices, does not use viruses to introduce genes into the cells or permanently alter a cell's genome.
    • Promising results shown for kidney cancer drug
      The drug pazopanib (Votrient) slowed the progression of advanced renal cell carcinoma, a form of kidney cancer, in patients by 54 percent, according to a new study.
    • Inhibiting serotonin in gut could cure osteoporosis
      An investigational drug that inhibits serotonin in the gut, administered orally once daily, effectively cured osteoporosis in mice and rats, reports a new article. Serotonin in the gut has been shown in recent research to stall bone formation. The finding could lead to new therapies that build new bone; most osteoporosis drugs only prevent the breakdown of old bone.
    • Cells send dirty laundry home to mom
      Understanding how aged and damaged mother cells manage to form new and undamaged daughter cells is one of the toughest riddles of aging, but scientists now know how yeast cells do it. In a groundbreaking study, researchers in Sweden show how the daughter cell uses a mechanical "conveyor belt" to dump damaged proteins in the mother cell.
    • Discovery may expand availability of bone marrow transplants by stopping fatal complications
      Scientists explain how an anti-inflammatory agent called "ATL146e" may significantly improve the likelihood of success for bone marrow transplants by preventing or halting the progression of graft-versus-host disease, a complication of bone marrow transplants in which the donor marrow attacks the host.
    • Biofilms: Discovery of a new mechanism of virus propagation
      Researchers have shown for the first time that certain viruses are capable of forming complex biofilm-like assemblies, similar to bacterial biofilms. These extracellular infectious structures may protect viruses from the immune system and enable them to spread efficiently from cell to cell. "Viral biofilms" would appear to be a major mechanism of propagation for certain viruses. They are therefore emerging as new and particularly attractive therapeutic targets.
    • Winning the war on weight
      An Australian study into the health beliefs and behaviors of obese people has found that the more severely obese a person is, the less likely they feel they can reduce their weight.
    • Growing cartilage: bioactive nanomaterial promotes growth of new cartilage
      Researchers have designed a bioactive nanomaterial that promotes the growth of new cartilage in vivo and without the use of expensive growth factors. The therapy is minimally invasive, utilizes bone marrow stem cells and produces natural cartilage. Unlike bone, cartilage does not grow back, and it cannot effectively be replaced. Countless people learn this all too well when they bring their bad knees, shoulders and elbows to an orthopedic surgeon.
    • Road mapping could be key to curing TB
      The complex chain of metabolic events in bacteria that lead to fatal diseases such as tuberculosis may be better understood using mathematical models, according to a new article.
