Our brains have a basic algorithm that enables us to not just recognize a traditional Thanksgiving meal, but the intelligence to ponder the broader implications of a bountiful harvest as well as good family and friends. “A relatively simple mathematical logic underlies our complex brain computations,” said Dr. Joe Z. Tsien, neuroscientist at…

Blind animals have had their vision partially restored using a revolutionary DNA editing technique that scientists say could in future be applied to a range of devastating genetic diseases. The study is the first to demonstrate that a gene editing tool, called Crispr, can be used to replace faulty genes with working…

A joint team of geneticists from the University of Geneva (UNIGE) and the Swiss Federal Institute of Technology in Lausanne (EPFL), Switzerland, demonstrated that the emergence of mammary glands in placental mammals and marsupials results from recycling certain ‘architect’ genes. The latter, known as Hox genes, are responsible for coordinating the formation…

The same algorithms that personalize movie recommendations and extract topics from oceans of text could bring doctors closer to diagnosing, treating and preventing disease on the basis of an individual’s unique genetic profile. In a study to be published Monday, Nov. 7 in Nature Genetics, researchers at Columbia and Princeton universities describe…

Prof. Clauss and his colleagues from Germany and the UK studied the shape of the ribcage in 126 terrestrial tetrapods — from prehistoric times up to the present day. With the aid of photogrammetry and computer imaging techniques, they compiled a dataset of digital 3D models of tetrapod skeletons. “This resulted in…

Testosterone. It’s often lauded as the hormone that makes males bigger, bolder, stronger. Now a pair of Duke University studies has identified one group of animals, the meerkats of the southern tip of Africa, in which females can produce even more testosterone than males. Female meerkats with naturally high levels of testosterone-related…

The capuchin monkeys of Serra da Capivara National Park in Brazil are well known for using rocks. They use them as hammers to crack open nuts. They use them for digging. They even use them to show off to potential mates. Now scientists report that they also spend time banging stones together,…

In a study that could one day help eliminate the tragic birth defects caused by Zika virus, scientists from the Florida campus of The Scripps Research Institute (TSRI) have elucidated how the virus attacks the brains of newborns, information that could accelerate the development of treatments. The study, led by TSRI Associate…

In classic experiments on frogs, scientists found that the amphibians’ urge to escape from dangerously hot water decreased significantly when the water temperature rose very gradually. In fact, sensitivity of many animals to temperature — including humans — is similarly affected by the rate of increase. Exactly why, however, has not been…

ISG faculty, Christina Palmer, Janet Sinsheimer, and previous ISG affiliate faculty member, Patrick Boudreault, have published a paper titled “Bilingual approach to online cancer genetics education for Deaf American Sign Language users produces greater knowledge and confidence than English text only: A randomized study,” with Disability and Health Journal, 2016. ABSTRACT: Introduction: Deaf American Sign Language-users…

Scientists have devised a powerful new tool for understanding how DNA controls gene activity in cells. The tool allows researchers to map at high resolution, across large swaths of a cell’s genome, which DNA nucleotides work to regulate gene activity. “This is the first method that enables us to simultaneously test thousands…

A new study by Johns Hopkins researchers suggests that a specialized area of the mosquito brain mixes tastes with smells to create unique and preferred flavors. The findings advance the possibility, they say, of identifying a substance that makes “human flavor” repulsive to the malaria-bearing species of the mosquitoes, so instead of…
