Altering the physiological circuits of flatworms makes them grow the heads of other species

A new research project at Tufts University in Massachusetts has seen biologists successfully induce flatworms of a specific species to grow the head and brain you'd expect to find on another species. Not only does the breakthrough add to our understanding of exactly what governs the growth of anatomy, but the knowledge gained may also have practical uses down the line, helping us better understand and even fix birth defects.

Salmon the first genetically engineered animal to get FDA approval for human consumption

Following what it describes as an "exhaustive and rigorous scientific review," the US Food and Drug Administration (FDA) today announced the approval of the first ever genetically-modified animal for human consumption. The engineered salmon in question has had its DNA altered in such a way that it grows to market-ready size in around half the time of regular salmon, and has now been declared safe for humans and safe for the environment.

Harnessing the survival powers of cancer cells could wipe out heart disease

The same genes that allow many cancers to proliferate and thrive could in the future be repurposed as a force for good. A study at the San Diego State University (SDSU) Heart Institute has found that mouse hearts regenerate cells better, causing the mice to live longer, when their progenitor cells are modified to over-express a key gene in cancer production. The researchers believe this could lead to a new treatment for people with heart disease or who have suffered from other age-related cardiac problems.

Hereditary gut microbes found to influence weight gain

A new study has determined that not only are bacteria naturally found in the gut involved in obesity, diabetes, and cardiovascular disease, but they are genetically inherited. Researchers at King's College London and Cornell University identified a highly-heritable bacterial family that is more common in individuals with low body weight and that could pave the way for genetics-based personalized probiotic therapies for obesity-related diseases.

Genetic differences between "identical" twins discovered

Although they only account for around three in every thousand deliveries, monozygotic, or "identical" twins are fertile fodder for crime writers and cop shows. This isn't surprising considering that DNA fingerprint testing is not able to genetically differentiate between the good and evil twin. But now German-based company Eurofins MWG Operon says it has found a way to do just that. Read More

Berkeley researchers find evidence for a "molecular fountain of youth"

The quest for longer and healthier life, if not immortality, has been part of the human experience since we evolved the ability to recognize the total annihilation of individual death. Our understanding of the biology of aging at the molecular level is advancing so rapidly that it appears inevitable that another decade or two of life will be enabled before long. A new step in what may be the right direction has just been published by researchers at the University of California, Berkeley. Read More
