Mushrooms may reduce the risk of cognitive decline by 50% A team from the Department of Psychological Medicine and Department of Biochemistry at the Yong Loo Lin School of Medicine at the National University of Singapore (NUS) has found that seniors who consume more than two standard portions of mushrooms weekly may have 50 per…

Aging reversed through mitochondrial DNA replenishment

Aging reversed through mitochondrial DNA replenishment Aging reversed through mitochondrial DNA replenishment Researchers have reversed wrinkled skin and hair loss, hallmarks of aging, in a mouse model. When a mutation leading to mitochondrial dysfunction is induced, the mouse develops wrinkled skin and extensive, visible hair loss in a matter of weeks. When the mitochondrial function…

Do viruses make us smarter? 

Public Release: 12-Jan-2015 A new study from Lund University in Sweden indicates that inherited viruses that are millions of years old play an important role in building up the complex networks that characterise the human brain. Researchers have long been aware that endogenous retroviruses constitute around five per cent of our DNA. For many years,…

Pesticide linked to 3 generations of disease

PUBLIC RELEASE DATE: 24-Jul-2014 Methoxychlor causes epigenetic changes PULLMAN, Wash. – Washington State University researchers say ancestral exposures to the pesticide methoxychlor may lead to adult onset kidney disease, ovarian disease and obesity in future generations. “What your great-grandmother was exposed to during pregnancy, like the pesticide methoxychlor, may promote a dramatic increase in your…

‘Alien’ life form is grown in a lab: Scientists add unnatural DNA strands to the genetic code of bacteria to create a new strain

  Researchers at the Scripps Research Institute in La Jolla, California, introduced DNA molecules not found in nature to a common bacterium The E. coli bugs are able to grow and reproduce as normal despite containing two extra letters in their genetic code Research involved overcoming a billion years of evolution to get the expanded…

New method for making human-based gelatin for gelatin-type desserts, marshmallows, candy and innumerable other products

Public release date: 13-Jul-2011 (HRR-Requested Repost)   Scientists are reporting development of a new approach for producing large quantities of human-derived gelatin that could become a substitute for some of the 300,000 tons of animal-based gelatin produced annually for gelatin-type desserts, marshmallows, candy and innumerable other products. Their study appears in ACS’s Journal of Agriculture…

Could dinosaur-age DNA cure GOUT? Reviving a 90 million-year-old protein could treat painful inflammation

Researchers have resurrected a prehistoric version of the enzyme uricase Uricase can break down uric acid, which can cause kidney stones and gout It is not produced in humans because of evolutionary changes that took place in the body over 20 million years ago By Daily Mail Reporter UPDATED:          08:05 EST, 21 February 2014  …

Fun With Genetic Engineering: Why Letting Students Tinker With Microorganisms Is Good For Education And Society

Posted: 01/14/2014  1:26 pm By Charles Gersbach, Assistant Professor, and Tom Katsouleas, Dean, Duke University’s Pratt School of Engineering Elaborate competitions to build the best robot or design cages to protect falling eggs have been a rite of passage for generations of engineering students. Today, there’s a new contest with the same creativity and competitive…

World’s oldest DNA is recovered from a 400,000-year-old thigh bone – and provides a new jigsaw piece in the history of evolution

Scientist reconstructed the mitochondrial genome from two grams of bone They found early humans shared a common ancestor with the Denisovans This was suprising as early humans were thought to share a common ancestor with Neanderthals due to similar skeletal features By  Ellie Zolfagharifard PUBLISHED: 13:09 EST, 4 December 2013 |  UPDATED: 13:47 EST, 4…
