Cancer-killing hydrogel stays in place until the job is done
12.3.2018 | Press monitoring
The cure for cancer might have been inside us all along – our own immune system. The trick is to give it a boost to find and destroy those rogue cells, and that's the focus of the field of immunotherapy. To that end, a new hydrogel has been developed that can be injected directly to the site of a tumor, where it stays to slowly release its...
Flower-shaped gold nanocrystals as photothermal agents against tumor cells
9.3.2018 | Press monitoring
Gold nanoflowers grown in starfruit juice are promising agents for photothermal cancer therapy. When injected into a tumor and irradiated with near-infrared laser light, the nanoflowers heat up and kill the cancer cells around them. Although photothermal therapy is an established idea, the agents developed so far have had drawbacks, explains Enyi...
Vaccines won’t overload your child’s immune system – or increase their risk of other infections
7.3.2018 | Press monitoring
As the global antivaccination movement grows, so has the number of U. S. parents who don’t vaccinate their children on time: As of 2015, an estimated 10% to 15% didn’t follow the recommended schedules for children under 2. Now, a new study shows that at least one of their fears – that vaccines overload the immune system and increase...
Why Barbra Streisand\'s cloned dogs aren\'t identical to the original pet
5.3.2018 | Press monitoring
Wouldn't it be wonderful if we could bring back a deceased loved one? Such ideas used to be pure science fiction, but recent advances in biotechnology seem to have brought this possibility within reach (at least for the wealthy). When American singer-actress Barbra Streisand lost her beloved dog Sammie last year, she decided to have her cloned....
Gene-editing reduces triglycerides, cholesterol by up to 50 percent
2.3.2018 | Press monitoring
Using a variation of CRISPR gene editing may be a potential strategy for mimicking the protective effects of a genetic mutation linked to lower cholesterol levels and heart disease risks, according to new mouse research from the Perelman School of Medicine at the University of Pennsylvania. People with naturally occurring mutations that cause a...
Scientists discover new nanoparticle, dubbed exomeres
28.2.2018 | Press monitoring
A new cellular messenger discovered by Weill Cornell Medicine scientists may help reveal how cancer cells co-opt the body's intercellular delivery service to spread to new locations in the body. In new paper the scientists show that a cutting-edge technique called asymmetric flow field-flow fractionation (AF4) can efficiently sort nano-sized...
Researchers create DNA wires 100 times more sensitive than other biosensors
26.2.2018 | Press monitoring
Scientists in Sweden today reported a nanoengineering innovation that offers hope for treatment of cancer, infections and other health problems – conductive wires of DNA enhanced with gold which could be used to electrically measure hundreds of biological processes simultaneously. While DNA nanowires have been in development for some time, the...
Typhoid Outbreak in Pakistan Linked to Extensively Drug-Resistant Bacteria
23.2.2018 | Press monitoring
The bacteria behind an ongoing outbreak of typhoid fever in Pakistan is a strain of Salmonella enterica that has become resistant to multiple antibiotic treatments by acquiring new DNA, according to a study reported this week (February 20) in mBio. More than 300 extensively drug-resistant cases of typhoid have been reported in the provinces...
Researchers find gene that may greatly increase strawberry production
21.2.2018 | Press monitoring
Researchers at the University of Maryland have identified and isolated a gene that is directly involved in the way strawberry plants grow, spread and produce fruit. With the ability to turn this gene on and off to produce runners (a long horizontal stem ideal for producing young strawberry plants for sale) or flowers (ideal to produce fruit) and...
Nano-factories produce anti-cancer drugs from inside tumors
19.2.2018 | Press monitoring
Like the horse of Troy, scientists at the Technion have developed a way to sneak synthetic cells right into tumor tissue, where they then begin producing cancer-fighting proteins from the inside. The technique was tested in both cell cultures and in mice, and found to be an effective treatment in both cases. The Technion scientists loaded...
