Dung beetles use Milky Way light to guide them

Dung beetles use light from the Milky Way to roll their balls of precious dung out of the way of competitors, scientists reported on Friday. Even though they have just a tiny brain and weak eyes, the beetles use the progressive gradient of light in the skies, provided by the…

Study of new mutations may show how cancers grow

Scientists have discovered two new genetic mutations that occur together in 71 percent of malignant melanoma tumors, an aggressive and deadly cancer of the skin, a study said. The mutations, detected in a part of the cancer genome that controls genes but not in the genes themselves, could aid understanding…

Researchers: Pesticides causing dramatic die-off in frog population worldwide

A plunge in the world’s population of frogs and toads may be blamed, at least in part, on farm pesticides, researchers in Germany said on Thursday. Tests of fungicides and insecticides, when used at recommended dilutions, killed 40 percent of frogs after seven days, and in one case, 100 percent…

Breakthrough: High pressure oxygen chambers repair ‘significant’ stroke damage

If you or someone you love have suffered a stroke and been forced into disability, a new breakthrough made by doctors at Tel Aviv University appears to offer hope for a “significant” level of recovery in the near future. Clinical trials conducted by Dr. Shai Efrati found that sitting inside…

Genetic analysis reveals how wolves evolved into dogs

Genetic sequencing of wolves and domesticated dogs has revealed a key insight into how that evolutionary change happened, finding that it has to do more with human diets than previously expected. To many dog owners, it probably won’t come as a surprise that food motivation has been a key driver…

Shakespeare’s sonnets and MLK audio file stored in DNA

All 154 Shakespeare sonnets have been spelled out in DNA to demonstrate the vast potential of genetic data storage His words have touched the lovelorn and been pored over by brooding teenagers for more than four hundred years, but now some of the most romantic poems ever penned have been…

Antibiotic-resistant diseases pose ‘apocalyptic’ threat, top expert says

Britain’s most senior medical adviser has warned MPs that the rise in drug-resistant diseases could trigger a national emergency comparable to a catastrophic terrorist attack, pandemic flu or major coastal flooding. Dame Sally Davies, the chief medical officer, said the threat from infections that are resistant to frontline antibiotics was…

Scientists resume controversial mutant bird flu research

Scientists who created a mutant bird flu virus said Wednesday they will resume the controversial research after taking a 12-month break to allay fears of the bug escaping the lab or falling into terrorist hands. Citing a “public health responsibility” to continue the work, the teams said research will resume…

Archaeologists uncover new fox species in South Africa

Archaeologists digging outside Johannesburg have unearthed a fossilised species of previously unknown fox, which they hope will help flesh out the evolutionary journey of modern canines. The new species — named Vulpes Skinneri after South African ecologist John Skinner — is thought to have lived about two million years ago.…

British scientists announce breakthrough in turning DNA into data storage

Scientists in Britain on Wednesday announced a breakthrough in the quest to turn DNA into a revolutionary form of data storage. A speck of man-made DNA can hold mountains of data that can be freeze-dried, shipped and stored, potentially for thousands of years, they said. The contents are “read” by…
