First supercentenarian-derived stem cells created

20.3.2020   |   Press monitoring

People who live more than 110 years, called supercentenarians, are remarkable not only because of their age, but also because of their incredible health. This elite group appears resistant to diseases such as Alzheimer's, heart disease and cancer that still affect even centenarians. However, we don't know why some people become supercentenarians...

Charged particles kill cancer by clogging up its waste disposal unit

18.3.2020   |   Press monitoring

Lysosomes are tiny sacs packed with enzymes and acids that degrade unwanted parts of the cell, before either recycling them or dumping them outside the cell walls, much like you'd take your trash out to the curb. Recent research has suggested lysosomes could play a role in Alzheimer's, where a dysfunctional disposal system can enable the buildup...

New kind of CRISPR technology to target RNA, including RNA viruses like coronavirus

16.3.2020   |   Press monitoring

CRISPR-based genetic screens have helped scientists identify genes that are key players in sickle-cell anemia, cancer immunotherapy, lung cancer metastasis, and many other diseases. However, these genetic screens are limited in scope: They can only edit or target DNA. For many regions of the human genome, targeting DNA may not be effective, and...

Copying a cancer trick prevents organ transplant rejection in rats

13.3.2020   |   Press monitoring

Cancer is a crafty foe, employing an array of tricky techniques to hide from the immune system while it grows. But now, scientists have managed to copy one of those strategies and use it for good, making new microparticles that permanently prevent transplanted tissue or even whole limbs from being rejected by the immune system. Transplanted...

Edible vaccines stored in cheap, easily transportable dissolving films

11.3.2020   |   Press monitoring

Vaccines have become an indispensable medical tool that offer protection from an ever-increasing range of diseases, but these living strains of viruses need to be kept cool to be effective. This is a real problem when it comes to distributing them to remote or developing areas, but a new delivery method from scientists at University of Texas at...

CRISPR treatment inserted directly into the body for first time

9.3.2020   |   Press monitoring

A person with a genetic condition that causes blindness has become the first to receive a CRISPR–Cas9 gene therapy administered directly into their body. The treatment is part of a landmark clinical trial to test the ability of CRISPR–Cas9 gene-editing techniques to remove mutations that cause a rare condition called Leber’s congenital amaurosis...

Edited bone marrow cells trigger striking tumor regression in mice

6.3.2020   |   Press monitoring

Immunotherapy is an increasingly powerful form of cancer treatment where the patient's own immune system is equipped with heightened abilities to take down the disease, and one promising arm of this is known as adoptive cell therapy. This involves using altered versions of a patient's own cells to trigger a more strong-handed response from their...

The hungry gut bacteria that enable waxworms to live on plastic waste

4.3.2020   |   Press monitoring

Plastic pollution is a monumental issue and one that isn’t going away anytime soon, but researchers are opening up new possibilities around how we could chip away at the problem.¨ Scientists working in this area at Canada’s Brandon University have made an exciting discovery, zeroing in on the mechanisms that enable a common species of caterpillar...

Novel formulation permits use of toxin from rattlesnake venom to treat chronic pain

2.3.2020   |   Press monitoring

Crotoxin, extracted from the venom of the South American rattlesnake Crotalus durissus terrificus, has been studied for almost a century for its analgesic, anti-inflammatory and antitumor activities and as an even more powerful muscle paralyzer than botulinum toxin. However, the toxicity of crotoxin limits its medicinal use. A new study,...

Identifying the source of water pollution using synthetic DNA sand

28.2.2020   |   Press monitoring

Sometimes it's helpful to follow a stream of water to find out where the water is coming from and where it's likely to go. Currently, only a few tracers for tracking fluids exist. But a large and complex network like groundwater requires lots of different tracers. "The main idea of the project is to build DNA based tracers," says Sulalit...
