New research shows regardless how similarly they may look, identical twins are not exactly genetically the same. Icelandic researchers sequenced DNA from 387 pairs of identical twins — those derived from a single fertilized egg — and their close relations. According to HuffPost, that allowed them to find early mutations that separate identical twins. A mutation is an alteration in a sequence of DNA that can influence physical features or susceptibility to certain diseases. On average, identical twins have 5.2 of these early genetic differences, the researchers found. But about 15% of identical twin pairs have more genetic differences, some of them up to 100. That could influence why one twin is taller or why one twin is at greater risk for certain cancers.
Malaria-causing parasites in Africa and southeast Asia are developing genetic mutations that pose grave health implications to the people there. UPI reports researchers collected samples in countries battling the mosquito-borne illness. They found genetic mutations that fuel resistance to a drug intended to prevent malaria in pregnant women and children are common. The gene mutations are linked with resistance to the drug sulfadoxine-pyrimethamine. The mutations were discovered in one-fourth of the samples collected in southeast Asia and one-third of those obtained in Africa.
Carlos Antonio Santamaria, the first 12-year old child to enter university in Mexico, spoke about the power of science and his dream to become a biomedical engineer.
Sinogene, a lab based in Beijing, became the first to clone a dog through gene-editing technology, which allows them to identify, copy, and reproduce genetic information from dogs. The first cloned canine, a beagle pup named Longlong, was born in May and two others followed suit. Gene-editing technology has many potential uses, allowing rare dog breeds to become more widespread, cloning of irreplaceable pets, and even removing genetic diseases before birth.
French astronaut Thomas Pesquet and Russian Oleg Novitskiy are due to return to Earth on Friday after a marathon 196-day trip. The 400-kilometre (250-mile) descent is expected to take around three hours and 20 minutes, with touchdown scheduled for 1430 GMT.
Researchers from Imperial College London have developed a gene therapy that has successfully prevented the development of Alzheimer’s disease in mice.
