Genetic studies reveal new causes of severe obesity in childhood
Scientists in Cambridge have discovered that the loss of a key segment of DNA can lead to severe childhood obesity. This is the first study to show that this kind of genetic alteration can cause obesity. The results are published ...
Evolution is unpredictable and irreversible, biologists show
Evolutionary theorist Stephen Jay Gould is famous for describing the evolution of humans and other conscious beings as a chance accident of history. If we could go back millions of years and "run the tape of life again," ...
EU food agency rejects France ban on Monsanto GM maize
Europe's food safety agency EFSA on Monday rejected the grounds for a temporary French ban on a genetically modified strain of maize made by US company Monsanto.
Scientists uncover genetic similarities between bats and dolphins
The evolution of similar traits in different species, a process known as convergent evolution, is widespread not only at the physical level, but also at the genetic level, according to new research led by ...
New brain gene gives us edge over apes, study suggests
Scientists have taken a step forward in helping to solve one of life's greatest mysteries – what makes us human?
A hidden genetic code: Researchers identify key differences in seemingly synonymous parts of the structure
Harvard scientists say they've solved a mystery that's nearly as old as science's understanding of the genetic code.
Novel polymer delivers genetic medicine, allows tracking
Theresa M. Reineke, associate professor of chemistry in the College of Science, and colleagues in her lab at Virginia Tech and at the University of Cincinnati have developed a new molecule that can travel ...
'Nanorobot' can be programmed to target different diseases
(Phys.org) -- University of Florida researchers have moved a step closer to treating diseases on a cellular level by creating a tiny particle that can be programmed to shut down the genetic production line that cranks out ...
Humans, chimpanzees and monkeys share DNA but not gene regulatory mechanisms
Humans share over 90% of their DNA with their primate cousins. The expression or activity patterns of genes differ across species in ways that help explain each species' distinct biology and behavior.
10-fold life span extension reported in simple organism
Scientists genetically increase algae biomass by more than 50 percent
Research at Iowa State University has led to discovery of a genetic method that can increase biomass in algae by 50 to 80 percent.
Belly fat or hip fat -- it really is all in your genes, researcher says
The age-old question of why men store fat in their bellies and women store it in their hips may have finally been answered: Genetically speaking, the fat tissue is almost completely different.
RNA Interference Delivered Using Nanoparticles Hits Target in Human Patients
(PhysOrg.com) -- A multi-institutional team of researchers and clinicians has published the first proof that a targeted nanoparticle can traffic into tumors, deliver double-stranded small interfering RNAs (siRNAs), and turn ...
Plants use circadian rhythms to prepare for battle with insects
In a study of the molecular underpinnings of plants' pest resistance, Rice University biologists have shown that plants both anticipate daytime raids by hungry insects and make sophisticated preparations to ...
