Researchers at the University of California, Los Angeles (UCLA) have figured out a way to extend the life of female fruit flies by 20 percent by manipulating what the school has called a “cellular time machine.” The biologists who carried out the work are hopeful that their findings will have implications for human aging and help fight off age-related diseases like Alzheimer’s and Parkinson’s.
Scientists have created light-driven spinning nanomachines that could kill cancer cells in just 60 seconds.
In laboratory tests, researchers showed how the molecules can be activated by ultraviolet light to spin up to three million times a second and drill through cell membranes.
In one test, it took between one and three minutes to cut through the outer shell of prostate cancer cell and destroy it.
Another application for the tiny ‘nanomachines’ might be to deliver therapeutic medicines, researchers say.
Scientists believe that the underlying cause of many neurological diseases, including Alzheimer’s and Parkinson’s, is the buildup of misfolded protein clusters in the brain. A new antibody treatment developed by a team at the NYU School of Medicine has the potential to target a feature of these misfolded proteins shared by several different diseases, promising a possible single treatment for a variety of neurological disorders.
Growing human transplant organs in pigs has become a more realistic prospect after scientists used advanced gene editing to remove threatening viruses from the animals’ DNA.
Porcine endogenous retroviruses are permanently embedded in the pig genome but research has shown they can infect human cells, posing a potential hazard.
The existence of the virus has been a major stumbling block preventing the development of genetically engineered pigs to provide kidneys and other organs for transplant into human patients.
That hurdle may now have been cleared away, according to new research reported in the journal Science.
Researchers at Harvard University and a private company used the precision gene editing tool Crispr-Cas9 combined with gene repair technology to deactivate 100 percent of the virus in a line of pig cells.
An American doctor will travel to the UK to examine Charlie Gard, the terminally ill baby whose parents are fighting in court to keep alive.
The parents of Charlie Gard have raised more than $1.6 million to take their son to the United States for an experimental treatment. Great Ormond Street Hospital, where Charlie is being treated, has intended to turn off his life support as multiple courts have ruled that prolonging the baby’s life would only cause him greater pain.
For the first time ever, blood-producing stem cells have been generated in a lab. Two separate teams of researchers have come up with differing ground-breaking methods to generate these important blood-forming cells, paving the way for the development of treatments for a variety of blood diseases and also offering a clear path towards an unlimited supply of lab-made blood for transfusions.
According to the Center for Disease Control, 1.25 million people suffer from type 1 diabetes in the US alone. So far, it can only be managed with diet and regular doses of insulin, but scientists at UT Health San Antonio have invented a way of curing the disease in mice that may one day do the same for humans even with type 2 diabetes.
Sperm that’s been loaded with chemotherapy drugs could be used to fight cancer in women.
The guided missile technique involves using drug-treated sperm to deliver the medicines to tumors deep inside the body.
The revolutionary treatment could help thousands of women affected by cancers of the reproductive system, which can be reached by the drug- carrying sperm. Cancer of the womb kills more than 2,000 women a year in the UK and cervical cancer claims the lives of around 900.
Treatment includes chemotherapy to try to poison the cancer cells before they spread.
But this also damages healthy cells. For years, scientists have been exploring ways to deliver toxic anti-cancer medicines directly to tumor sites, leaving healthy tissues unscathed.
One method used bacteria as a form of transport, as they can penetrate the body easily.
