Biosynthesis pathway of a new DNA nucleobase elucidated
DNA is composed of nucleobases represented by the letters A, T, G and C. They form the basis of the genetic code and are present in all living beings. But in a bacteriophage, another base, represented by the letter Z, exists. This exception, the only.....»»

Researchers identify last remaining steps in the biosynthesis of tropane alkaloids from coca
Tropane alkaloids are a particular class of plant-derived compounds that have been exploited by mankind since the domestication of medicinal plants. The distribution of these alkaloids is scattered amongst the flowering plants and the two most studie.....»»
Shining a new light on the importance of a critical photosynthesis pathway in plants
Photosynthesis is one of the most important chemical reactions, not just for plants but also for the entire world. The impact and thus the importance of photosynthesis can scarcely be underestimated. Thus, it makes sense that science has long been fa.....»»

Researchers in the Princeton University Department of Chemistry have discovered a new multi-step pathway through which bacteria found in the mammalian gut produce antimicrobial peptides......»»
COP27: Net Zero guidelines aim to drive higher standards and counter "greenwashing" accusations
To counter accusations of greenwashing and vague sustainability targets, a clear set of guidelines, has today been published at COP27, establishing standards for the pathway to net zero, by the International Standards Organization......»»
How community-engaged archaeology can be a pathway to reconciliation
We are standing in a circle on an expansive beach in front of an ancient rock-walled fish-trap—one of many archaeological sites on the small island of Xwe'etay (Lasqueti) in the Salish Sea between Vancouver Island and the British Columbian mainland.....»»
Catnip and pea aphids came up with different ways to make the same molecule
In a new study in PNAS, a research team at the Max Planck Institute for Chemical Ecology in Jena, Germany, shows that both catnip and pea aphids produce the substance nepetalactone, even though the plant and the insect evolved the biosynthesis of thi.....»»
Missing pathway in lysosome underlies newly discovered human disease
In a rare disease called mucolipidosis type II, people's hearts and abdomens swell, and their bones grow malformed......»»
Desperate Families Are Crowdsourcing Rescues on Social Media In the Path of Hurricane Ian

The pathway to 90% clean electricity is mostly clear. The last 10%, not so much
Six different approaches—with pros and cons—for getting to a 100% carbon-free grid. Enlarge (credit: picture alliance via Getty) The United States gets about 40 percent of its electricity from carbon-free sources, includin.....»»
Contact between wild birds and backyard chickens is risky
Wild birds come into contact with backyard chicken flocks more frequently than people realize, creating a pathway for pathogens to transmit back and forth, according to new research from the University of Georgia. Such pathways increase the risk for.....»»
Dual temperature control system to regulate isoprene biosynthesis in baker"s yeast
Baker's yeast, Saccharomyces cerevisiae, has been extensively engineered to produce a vast variety of chemicals that are not naturally produced by yeast, including the important monomer for synthetic rubber, isoprene. However, all organisms are natur.....»»
How does the autophagic pathway regulate low-nitrogen tolerance in tomato?
Nitrogen (N) deficiency first affects the N uptake and assimilation systems of plants. Nitrate, the main source of plant N, is absorbed and transported by nitrate transporters. Nitrate can be metabolized directly in the roots after absorption and sto.....»»
Study unveils alkaloids and chlorophyll biosynthesis in lotus plumule
Bisbenzylisoquinoline alkaloids (bis-BIAs) and chlorophyll (Chl) are predominantly accumulated in lotus plumule, which is a green tissue in the middle of seeds. Although bis-BIAs and Chl endow lotus plumule with important medicinal value and environm.....»»
New analysis shows how sulfur clouds can form in Venus" atmosphere
Scientists using sophisticated computational chemistry techniques have identified a new pathway for how sulfur particles can form in the atmosphere of Venus. These results may help to understand the long sought-after identity of the mysterious ultrav.....»»
Apple trees" natural response to virus mirrors genetic modification mechanism, study shows
Apple trees respond to a common viral infection by targeting a gene in the same pathway that genetic scientists are aiming at, find scientists from The University of Manchester. The discovery published in Current Biology shows that the fruit trees, w.....»»
