Starch synthesis from carbon dioxide

The artificial route can produce starch from CO2 with an efficiency 8.5-fold higher than starch biosynthesis in maize


Chinese scientists recently reported a de novo route for artificial starch synthesis from carbon dioxide (CO2) for the first time. Relevant results were published in Science on Sept. 24. The new route makes it possible to shift the mode of starch production from traditional agricultural planting ...

Cruel twist: Exercise reduces calories burned at rest in individuals with obesity

For every calorie they spend on exercise they save about half a calorie on resting


Exercise reduces the amount of calories burned at rest in people with obesity, according to a new study by researchers from the Shenzhen Institute of Advanced Technology (SIAT) of the Chinese Academy of Sciences and the University of Roehampton. The study, published in Current Biology on August ...

Integrated approach streamlines genome sequencing to advance single-cell technology


A single cell can reveal much about the biological world through genomic sequencing. Scientists can compare a single, isolated cell to other samples, analyzing the differences and similarities to better understand how the organisms originated and evolved — or even to discover entirely new ...

Single-cell test can reveal precisely how drugs kill cancer cells

New method sees how pharmaceuticals induce cancer cell death and how cancer cells adapt


Cancer cells are smart when it comes to anti-cancer drugs, evolving and becoming resistant to even the strongest chemotherapies over time. To combat this evasive behavior, researchers have developed a method named D2O-probed CANcer Susceptibility Test Ramanometry (D2O-CANST-R) to see, at ...

Direct detection of circulating tumor cells in blood samples

Enhanced Glow


Tumor cells circulating in blood are markers for the early detection and prognosis of cancer. However, detection of these cells is challenging because of their scarcity. In the journal Angewandte Chemie, scientists have now introduced an ultrasensitive method for the direct detection of ...

Faster genome evolution methods to transform yeast for industrial biotechnology


Scientists have created a new way of speeding up the genome evolution of baker's yeast Saccharomyces cerevisiae, the same yeast people use for bread and beer production, to develop a synthetic yeast strain that can be transformed on demand for use in various industrial applications. A research ...

Detecting bloodstains - with an antimalarial compound

Artemisinin-Luminol reduces false positive results of crime scene blood stains


As seen on crime shows, investigators use a combination of luminol and other substances to light up bloodstains at crime scenes. But now, researchers report that combining luminol with artemisinin, a natural peroxide and antimalarial treatment, reduces the risk of false positives compared to the ...


Stem cells help researchers study the effects of pollution on human health


A recent study shows that embryonic stem cells could serve as a model to evaluate the physiological effects of environmental pollutants efficiently and cost-effectively. The use of stem cells has found another facade. In the world we live in today, people are constantly exposed to artificial ...


New X-ray technique distinguishes between that which previously looked the same

A new method forms the basis for the widespread use of an X-ray technique which distinguishing types of tissue that normally appear the same in conventional X-ray images


Traditional X-ray images can clearly distinguish between bones and soft tissue, with muscles, cartilage, tendons and soft-tissue tumours all look virtually identical. The phase-contrast technique developed a few years ago at the Paul Scherrer Institute enables X-ray images to be produced that ...


New visible light photocatalyst kills bacteria, even after light turned off


In the battle against bacteria, researchers at the University of Illinois have developed a powerful new weapon – an enhanced photocatalytic disinfection process that uses visible light to destroy harmful bacteria and viruses, even in the dark. Based upon a new catalyst, the disinfection process ...
