Scientists in China have genetically modified human embryos in a world first that has re-ignited the debate over the ethics and safety of genetic therapies that have the potential to prevent inherited diseases.
The work raises fresh questions over whether restrictions should be placed on a new wave …Life Sciences
The simple act of thinking can accelerate the growth of many brain tumors.
That's the conclusion of a paper in Cell published Thursday that showed how activity in the cerebral cortex affected high-grade gliomas, which represent about 80 percent of all malignant brain tumors in people.
"This tumor is …The Brain
A possible alternative to controversial three-parent babies
While mitochondrial DNA transfers, or “three-parent babies,” are now legal in the United Kingdom, the debate (largely an ethical one) is still ongoing in the United States. According to a study published today in Cell, researchers at the …DNA
Researchers in the US have raised hopes for a simple genetic therapy that could prevent devastating diseases being passed on from mothers to their children.
A team at the Salk Institute in California demonstrated in mice that a single injection into embryos could rewrite faults in the DNA of …Genetics
The possibilities open to a person rendered invisible have been well explored in the worlds of science fiction and philosophy, not to mention the minds of adolescents.
Now neuroscientists in Sweden have simulated the effect using virtual reality and found, perhaps unsurprisingly, that the sensation …Virtual Reality
Tens of thousands of years ago, the rise of humanity as we know it began. Modern humans spread from Africa to Europe and Asia, which were already populated by older Neanderthal cultures. The two groups interbred, adding some Neanderthal DNA to our present-day genes. The relatively sophisticated …Neanderthals
For the first time, signals relating to the constant ringing noise of tinnitus have been mapped across the brain of a patient undergoing surgery.
In this rare case, a man with tinnitus was being monitored to trace his epileptic seizures, with 164 electrodes placed directly onto his brain.

How did our image of childhood evolve so that behaviors once considered normal are now considered a disorder?
I met Aiden in 2008 when he was seven years old. The previous year, he had moved with his family from New York to California, and the transition had been difficult. He missed his friends in …Childhood
Critics warned that China was becoming the ‘Wild West’ of genetic research
China has been ordered to ‘rein in’ scientists who have edited the DNA of human embryos for the first time, a practice banned in Europe.
In a world’s first, researchers at the Sun Yat-sen University in Guangzhou confirmed they …Asia

The number of adults who have survived childhood cancer in the United States has increased—but they face chronic health problems related to their …Cancer
Genetic tests for cancer can run thousands of dollars, but Color Genomics plans to change that: it's offering testing for the cancer risk variants BRCA1 and BRCA2 — as well as 17 others — for $249, starting today. By comparison, Myriad Genetics' similar test costs about $4,000.
Scientists in Australia, home to some of the most poisonous creatures on Earth, have made an important discovery about spider venom that eventually could lead to a new class of painkillers.
Spiders use their venom to immobilize or kill their prey. Researchers from the University of Queensland …Scientific Research
