Scientists find another mechanism that destroys tumor cells

Cells don't like to be alone. In the early stages of tumor formation, a cell might be pushed out of its normal home environment due to excessive growth. But a cell normally responds to this homeless state by dismantling its nucleus, packing up its DNA, and offering itself to be eaten by immune system cells. Simply put, the homeless cell kills itself. This process, known as apoptosis, typically stops potential cancer cells before they have a chance to proliferate.

Reliv International's chief scientific officer suggests tips to improvise lifestyle as age increases

According to the Centers for Disease Control and Prevention, the United States is on the "brink of a longevity revolution." In fact, by 2030, one in every five Americans will be over the age of 65. So, what can adults do now to ensure that they continue to enjoy a great lifestyle in their later years? In honor of Healthy Aging Month this September, Dr. Carl Hastings, chief scientific officer of Reliv International, offers some advice.

Study finds long-term exposure to progesterone may lead to growth of tumors

Scientists at Michigan State University have found exposure to the hormone progesterone activates genes that trigger inflammation in the mammary gland.

Fractal patterns and microchannels to advance tissue engineering

Utilizing fractal patterns similar to those created by lightning strikes, Victor Ugaz, associate professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, has created a network of microchannels that could advance the field of tissue engineering by serving as a three-dimensional vasculature for the support of larger tissue constructs, such as human organs.

New tool for virtual surgery simulates blood flow - helps plan child's delicate heart surgery

Researchers at the Georgia Institute of Technology, collaborating with pediatric cardiologists and surgeons at The Children's Hospital of Philadelphia, have developed a tool for virtual surgery that allows heart surgeons to view the predicted effects of different surgical approaches. By manipulating three-dimensional cardiac magnetic resonance images of a patient's specific anatomy, physicians can compare how alternative approaches affect blood flow and expected outcomes, and can select the best approach for each patient before entering the operating room.

Mal-illumination - the silent epidemic

Most of human history has witnessed people living and working outdoors during the light of day, absorbing "life-charging" full-spectrum solar energy from the sky. An average of 10 hours daily in the sunlight, 70 hours weekly, was common for eons.

Time examines how zinc supplements may help save children worldwide

TIME examines the "quiet revolution [now] under way" to treat diarrhea using zinc supplements. The magazine reports that globally the disease "kills an astonishing 1.6 million children under 5 every year," according to the WHO.

Changes in mtDNA can cause premature ageing

The normal ageing process has long been linked to problems with cell respiration, the process through which the cells extract energy from nutrients. Researchers at the Swedish medical university Karolinska Institutet have now shown how certain proteins that are synthesised in the cellular mitochondria - popularly known as the cells' power plants - become unstable and disintegrate, which in turn can impair cell respiration and cause premature ageing.

Colon cancer may yield to cellular sugar starvation

Scientists at the Johns Hopkins Kimmel Cancer Center have discovered how two cancer-promoting genes enhance a tumor's capacity to grow and survive under conditions where normal cells die.

New bio-hybrid materials could be used as sensors, catalysts, drug-delivery systems, more

Bacteria play a role in myriad industrial processes from fermentation to cleaning up environmental pollution. But floating freely in solution, the microbial cells constantly multiply, generating biomass that must be removed periodically, causing downtime. Additionally, the microorganisms cannot be localized to a specific region of interest.

Breastfeeding can save 1.3 million children annually, WHO says

About 1.3 million children's lives could be saved each year by teaching new mothers how to breastfeed, but many women do not receive help and stop trying, the WHO said on Friday ahead of the start of World Breastfeeding Week, which runs from August 1 through August 7, Reuters reports.

Common food additive lecithin may help control blood lipids and reduce disease risk

Scientists at Washington University School of Medicine in St. Louis have identified a substance in the liver that helps process fat and glucose. That substance is a component of the common food additive lecithin, and researchers speculate it may one day be possible to use lecithin products to control blood lipids and reduce risk for diabetes, hypertension or cardiovascular disease using treatments delivered in food rather than medication.

No evidence for superior nutritional content of organic produce

There is no evidence that organically produced foods are nutritionally superior to conventionally produced foodstuffs, according to a study published in The American Journal of Clinical Nutrition.

Research adds to growing understanding of the metabolic consequences of assisted reproductive techniques

Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, finds that assisted reproductive techniques alter the expression of genes that are important for metabolism and the transport of nutrients in the placenta of mice.

Enzyme implicated in blood flow in Alzheimer’s, disease progression

Researchers have discovered that the enzyme, endothelin converting enzyme-2 (ECE-2), may cause the decrease in blood flow in the brain seen in Alzheimer's disease and contribute to progression of the disease.

Turmeric spice and vitamin D may help clear amyloid plaques found in Alzheimer's

UCLA scientists and colleagues from UC Riverside and the Human BioMolecular Research Institute have found that a form of vitamin D, together with a chemical found in turmeric spice called curcumin, may help stimulate the immune system to clear the brain of amyloid beta, which forms the plaques considered the hallmark of Alzheimer's disease.

Cells use import machinery to export their goods as well

In the bustling economy of the cell, little bubbles called vesicles serve as container ships, ferrying cargo to and from the port - the cell membrane. Some of these vesicles, called post-Golgi vesicles, export cargo made by the cell's protein factory.
