Genetically engineered yeast makes medicinal plant products

2.9.2020   |   Press monitoring

Tropane alkaloids, like most other plant natural products, are still typically extracted from natural sources, but this approach has many pitfalls. For instance, vulnerability to weather and market fluctuations can limit access for both patients and researchers, and extraction can be environmentally harmful. In addition, plants typically contain...

ISS experiment shows bacteria can survive in space for years, could seed planets

31.8.2020   |   Press monitoring

A new experiment placing bacteria on the outside of the International Space Station (ISS) has found that micro-organisms can survive in space for years, or even decades. The study lends weight to the idea that life could travel between planets. Bacteria are hardy little creatures. They thrive in practically every environment on Earth, from deep...

750 Million GM Mosquitoes Will Be Released in the Florida Keys

28.8.2020   |   Press monitoring

With the aim of reducing rates of the mosquito-borne illnesses yellow fever and dengue, a pilot program will release 750 million genetically modified mosquitoes into the Florida Keys in 2021, thanks to approval by the barrier islands’ Mosquito Control District Board of Commissioners at a meeting on Tuesday (August 18). The strain of GM...

Transplanted brown-fat-like cells hold promise for obesity and diabetes

26.8.2020   |   Press monitoring

Obesity is the main cause of type 2 diabetes and related chronic illnesses that together will kill more people around the globe this year than the Covid-19 coronavirus. Scientists at Joslin Diabetes Center have delivered a proof of concept for a novel cell-based therapy against this dangerous condition. The potential therapy for obesity would...

Natural enzyme re-engineered to tackle stroke and spinal cord damage

24.8.2020   |   Press monitoring

When nerve cells become damaged through a severe injury such as spinal cord damage or a stroke, the body’s natural defences go to work to limit the damage. This forms what is known as a glial scar, which protects against further injury but can impede long-term nerve repair. Scientists have now redesigned an enzyme found in nature that selectively...

First functioning mini human hearts grown from stem cells

21.8.2020   |   Press monitoring

Scientists have created the first-ever functional miniature human hearts in the lab. Grown from stem cells, these heart “organoids” are made up of all primary heart cell types and have functioning chambers and vasculature. They could help us understand how hearts develop and build better models for treating disease. To make these human heart...

Capsules loaded with stem cells help repair heart damage in mice

19.8.2020   |   Press monitoring

Heart attacks are a leading cause of death, largely because the damage caused by one can lead to more later. Now researchers at Rice University have developed a new way to repair heart tissue and reduce scarring, by implanting capsules loaded with stem cells. When a person suffers a heart attack, the organ repairs itself as best it can, patching...

Nanoparticles to immunize plants against heat stress

17.8.2020   |   Press monitoring

Civil and Environmental Engineering's Greg Lowry and his team are creating nanoparticles (NP) and NP coatings that will revolutionize the agricultural industry. Already, his research has demonstrated that NPs that are coated with the right polymers can be applied to plant leaves with 99 percent uptake – orders of magnitude more efficient than...

Third breakthrough demonstrates photosynthetic hacks can boost yield, conserve water

14.8.2020   |   Press monitoring

Plants are factories that manufacture yield from light and carbon dioxide – but parts of this complex process, called photosynthesis, are hindered by a lack of raw materials and machinery. To optimize production, scientists from the University of Essex have resolved two major photosynthetic bottlenecks to boost plant productivity by 27 percent in...

Algal blue light switch control of electrical excitation in plants

12.8.2020   |   Press monitoring

Optogenetics denotes the manipulation of cellular processes by light-based biological techniques. An international research team led by the Würzburg plant scientists Rainer Hedrich, Georg Nagel and Dirk Becker has succeeded in applying this method to higher plants: Light impulses can now be used to trigger electrical excitation in plants. "With...
