How to make better biofuels? Convince yeast it is not starving

18.11.2019   |   Press monitoring

Yeast already helps make bread and beer and cranks out the biofuel ethanol, but scientists believe it can be used to create an even more efficient fuel called isobutanol. Normally, yeast only creates a tiny amount of isobutanol. Now researchers at Princeton University have discovered a genetic switch that significantly ramps up ...

Better biosensor technology created for stem cells

15.11.2019   |   Press monitoring

A Rutgers-led team has created better biosensor technology that may help lead to safe stem cell therapies for treating Alzheimer's and Parkinson's diseases and other neurological disorders. The technology, which features a unique graphene and gold-based platform and high-tech imaging, monitors the fate of stem cells by detecting genetic...

Bacteria being genetically engineered to locate buried explosives

13.11.2019   |   Press monitoring

Raytheon is recruiting glowing microbes to help search for buried explosives. Being developed under a DARPA contract, the company is working with Worcester Polytechnic Institute to use synthetic biology techniques to produce two new strains of bacteria – one to seek out hidden explosives below ground and a second on the surface that glows when...

Drones used to release sterile insects to disrupt orchard pests

11.11.2019   |   Press monitoring

Chris Adams and Larry Gut, entomologists in the College of Agriculture and Natural Resources at Michigan State University, are using large drones to release sterile insects as a more sustainable and cost-effective way to disrupt reproduction of codling moths, or CM, in apple orchards. CM is the principle apple pest that apple growers must control...

Tiny transporters could deliver treatment to stroke patients

8.11.2019   |   Press monitoring

Swarms of nanoparticles which are 15,000 times smaller than a pinhead may be able to deliver vital drugs to the brain, offering new hope to patients in the early stages of a stroke. The research, carried out at The University of Manchester, shows that tiny vesicles called liposomes, just 100 nanometres in diameter can translocate through the...

Peering into a more human petri dish

6.11.2019   |   Press monitoring

Cell culture media, the cocktail of chemicals and nutrients that keep cells alive and thriving in a dish, have been an essential tool of biology for more than 70 years. Remarkably, the composition of these potions hasn't fundamentally changed much over that time, primarily because they deliver what scientists need: Cells that stay viable and...

Blood vessels incorporated into 3D-printed living skin

4.11.2019   |   Press monitoring

It certainly would be great if instead of having to be harvested from a patient's own body, permanent skin grafts could be 3D-printed as needed. Well, we may be getting a little closer to that point, as scientists have now bioprinted living skin complete with blood vessels. First of all, there already are commercially-available 3D-bioprinted...

The world’s best drink cooler may come from pineapple scraps

1.11.2019   |   Press monitoring

When life gives you pineapples – and hundreds of millions of tons of pineapple waste – what do you do? Engineers in Singapore and Vietnam decided to turn all those scraps into something useful – insulation for their pi?a coladas. Not only does their new material keep drinks chilled better than many commercial coolers, but it could also offer a...

Gold-DNA nanosunflowers for efficient gene silencing and controlled transformation

30.10.2019   |   Press monitoring

Developing an efficient delivery system for enhanced and controlled gene interference-based therapeutics is an existing challenge in molecular biology. The advancing field of nanotechnology can provide an effective, cross-disciplinary strategy to facilitate nucleic acid delivery. In a new report, Shuaidong Huo and colleagues in the...

Implantable cancer traps could replace biopsies for tumor detection

28.10.2019   |   Press monitoring

One of the main things that makes cancer so deadly is its ability to spread throughout the body, so it’s important for doctors to detect it before it does. Rather than the invasive process of taking biopsies of organs, researchers from the University of Michigan have developed “cancer traps” that can be implanted just below the skin. In tests on...
