Microorganisms often assemble natural products similar to industrial assembly lines. Certain enzymes, non-ribosomal peptide synthetases (NRPS) play a key role in this process. Biotechnologists at Goethe University have now been able to discover how these enzymes interact with each other. This brings them one step closer to their goal of engineering the production of such peptide natural products.
Scientists studying a valuable, but vulnerable, species of poplar have identified the genetic mechanism responsible for the species' inability to resist a pervasive and deadly disease. Their finding, published in the Proceedings of the National Academy of Sciences, could lead to more successful hybrid poplar varieties for increased biofuels and forestry production and protect native trees against infection.
In the ongoing chemical battles among bacteria and their microbial neighbors, a new toxin has been uncovered. This unfamiliar toxin behaves in a familiar way. Its actions against other bacteria resemble the mechanisms of cholera, pertussis and diphtheria toxins. Some bacteria deploying this toxin have safeguards against self-poisoning.
Like fingerprints, no 3D printer is exactly the same. That's the takeaway from a new University at Buffalo-led study that describes what's believed to be the first accurate method for tracing a 3D-printed object to the machine it came from. The advancement could help law enforcement and intelligence agencies track the origin of 3D-printed guns, counterfeit products and other goods.
Ames Laboratory has developed a method to measure magnetic properties of superconducting and magnetic materials that exhibit unusual quantum behavior at very low temperatures in high magnetic fields.
Flares from the youngest red dwarfs surveyed are 100 to 1,000 times more energetic than when the stars are older. This younger age is when terrestrial planets are forming around their stars.
Girls who play video games are three times more likely to choose physical science, technology, engineering or maths (PSTEM) degrees compared to their non-gaming counterparts, according to new research from the University of Surrey.
A Purdue University-led team developed a new material and manufacturing process that would make one way to use solar power -- as heat energy -- more efficient in generating electricity.
Collapsible dog bowls and bendable straws seem to work on a common principle, snapping into stable and useful states, but mechanisms have remained elusive. Now a team led by polymer scientists at UMass Amherst discuss how 'pre-stress' built into the structure helps them function.
Diamond nanomaterials are considered hot candidates for low-cost photocatalysts. They can be activated by light and can then accelerate certain reactions between water and CO2 and produce carbon-neutral 'solar fuels'. The EU project DIACAT has now doped such diamond materials with boron and shown at BESSY II how this could significantly improve the photocatalytic properties.
