Decoy nanoparticles can block HIV and prevent infection

24.4.2020   |   Press monitoring

Flipping the standard viral drug targeting approach on its head, engineers at the University of California San Diego have developed a promising new "nanosponge" method for preventing HIV from proliferating in the body: coating polymer nanoparticles with the membranes of T helper cells and turning them into decoys to intercept viral particles and...

CRISPR combines with stem cell therapy to reverse diabetes in mice

22.4.2020   |   Press monitoring

For a few years now, scientists at Washington University have been working on techniques to turn stem cells into pancreatic beta cells as a way of addressing insulin shortages in diabetics. After some promising recent strides, the team is now reporting another exciting breakthrough, combining this technique with the CRISPR gene-editing tool to...

Carbon nanotubes embedded in leaves detect chemical signals that are produced when a plant is damaged

20.4.2020   |   Press monitoring

MIT engineers have developed a way to closely track how plants respond to stresses such as injury, infection, and light damage, using sensors made of carbon nanotubes. These sensors can be embedded in plant leaves, where they report on hydrogen peroxide signaling waves. Plants use hydrogen peroxide to communicate within their leaves, sending out...

Engineered proteins calm cytokine storms caused by severe infections

17.4.2020   |   Press monitoring

When it’s working properly, the immune system is a powerful ally to keep us healthy – but when it turns against us, the results can be devastating. A “cytokine storm” is a dangerous kind of immune overreaction that can be triggered by infection or other treatments. Now, MIT researchers have engineered proteins that show early promise in mopping up...

Research uncovers microbial life in radioactive waste storage sites

15.4.2020   |   Press monitoring

Two new research papers from The University of Manchester, working with colleagues at Sellafield Limited and the National Nuclear Laboratory show that microbes can actively colonize some of the most intensively radioactive waste storage sites in Europe. When nuclear facilities such as Sellafield were designed and built more than 50 years ago, it...

Researchers create unique DNA biosensor for early stage disease detection

13.4.2020   |   Press monitoring

Disease detection at an early stage is one of the biggest challenges biochemists and materials scientists are trying to meet by combining their expertise at Missouri S&T. The researchers used nanotechnology in biomedical diagnostics – a process called nanodiagnostics – to create a new, ultrasensitive DNA biosensor. The new sensor could...

DARPA program looks to use biotech to prevent jet lag and diarrhea

10.4.2020   |   Press monitoring

DARPA is planning to develop a travel adapter for the human body. Called the ADvanced Acclimation and Protection Tool for Environmental Readiness (ADAPTER), the new program aims to produce an implantable or ingestible bioelectronic device to help soldiers handle jet lag and diarrhea. This is bad enough for tourists or business people, but for...

Polio, measles, other diseases set to surge as COVID-19 forces suspension of vaccination campaigns

8.4.2020   |   Press monitoring

Global Polio Eradication Initiative on 24 March recommended suspending polio vaccination campaigns until the second half of the year. Two days later Strategic Advisory Group of Experts on Immunization (SAGE) issued a broader call, recommending that all preventive mass vaccination campaigns for other diseases be postponed. But experts say the...

Sea sponge molecule stops cervical cancer cell growth in the lab

6.4.2020   |   Press monitoring

Scientists at the University of South Carolina have been investigating the cancer-fighting potential of sea sponges for some time, uncovering compounds that proved effective in tackling melanomas, prostate and pancreatic cancers. Their latest work centers on cervical cancer, the fourth most common cancer type among women, with 13,800 new...

Heart attack on a chip: Scientists model conditions of ischemia on a microfluidic device

3.4.2020   |   Press monitoring

Researchers led by biomedical engineers at Tufts University invented a microfluidic chip containing cardiac cells that is capable of mimicking hypoxic conditions following a heart attack – specifically when an artery is blocked in the heart and then unblocked after treatment. The chip contains multiplexed arrays of electronic sensors placed...
