Redefining knowledge of elderly people throughout history
An archaeologist is set to redefine what we know about elderly people in cultures throughout history, and dispel the myth that most people didn't live much past 40 prior to modern medicine.

 Gene fusion shifts cell activity into high gear, causing some cancer
The fusion of two adjacent genes can cause cancer by kicking mitochondria into overdrive and increasing the amount of fuel available for rampant cell growth, researchers at Columbia University Medical Center (CUMC) have discovered. They also found that drugs that target this newly identified cancer pathway can prevent tumor growth, both in human cancer cells and mice with a form of brain cancer.

Growing organs a few ink drops at a time
Researchers refine method of making bio-ink droplets stick to each other, enabling 3D printing of highly complex biological structures with a wide variety of cell types using inkjet printers
Researchers develop a finely tuned enzyme-driven crosslinking method to glue together biological ink droplets and extend the range of cell types that can be handled by inkjet bioprinting. Such printing holds strong promise for regenerative medicine, such as in use of iPS cells.

Weekly fish consumption linked to better sleep, higher IQ
Regular fish consumption has been shown to improve cognition. It's also been known to help with sleep. A new study connects all three for the first time. The team found that children who eat fish at least once a week sleep better and have higher IQs by an average of 4 points.
Gut reaction: Repeated mild food poisoning triggers chronic disease
Small bacterial infections that may go unnoticed and which the body easily clears without treatment, such as occurs during mild food poisoning, nevertheless can start a chain of events that leads to chronic inflammation and potentially life-threatening colitis

Humidity may prove breaking point for some areas as temperatures rise, says study

Climate scientists say that killer heat waves will become increasingly prevalent in many regions as climate warms. However, most projections leave out a major factor that could worsen things: humidity, which can greatly magnify the effects of heat alone. Now, a new global study projects that in coming decades the effects of high humidity in many areas will dramatically increase.
Pain-free skin patch responds to sugar levels for management of type 2 diabetes

Researchers have devised a biochemically formulated patch of dissolvable microneedles for the treatment of type 2 diabetes. The biochemical formula of mineralized compounds in the patch responds to blood chemistry to manage glucose automatically. In a proof-of-concept study performed with mice, the researchers showed that the chemicals interact in the bloodstream to regulate blood sugar for days at a time.

By the beginning of the 15th century, coconuts entered Africa and slowly spread to Europe. It closely resembles a rugby ball with roughly three sides. The size is about 20 to 30 cm long. The palm generally grows in tropical climates and today it is found in almost all the tropics in the Indian and Pacific Oceans, ranging from the Hawaiian islands, West Indies, Jamaica, Africa, India, Sri Lanka, Myanmar etc. Coconut water contains energy, protein, fat, carbohydrates, sugar, and dietary fiber. The mineral & vitamin content includes calcium, iron, magnesium, phosphorous, potassium, sodium, zinc, copper, manganese, vitamin B6, vitamin C, and vitamin E, as well as vitamin K, thiamin, riboflavin, niacin, pantothenic acid, and folate. Some of the byproducts of coconuts include mature coconut meat, coconut milk, coconut oil, coconut wine, coconut vinegar, and many more. C...
