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.....»»
Scientists confirm thermonuclear fusion in a sheared-flow Z-pinch device
In findings that could help advance another "viable pathway" to fusion energy, research led by Lawrence Livermore National Laboratory (LLNL) physicists has proven the existence of neutrons produced through thermonuclear reactions from a sheared-flow.....»»
Genetic sequence allows photosynthetic organisms to stably produce ethylene
For decades engineers have dreamed of programming organisms to sustainably produce ethylene, a chemical that is nicknamed "the king of petrochemicals" for its importance in plastics. Now, one hopeful pathway to this petrochemical is nearing reality,.....»»
Predicting the efficiency of oxygen-evolving electrolysis on the moon and Mars
Scientists at The University of Manchester and The University of Glasgow have today provided more insight into the possibility of establishing a pathway to generate oxygen for humans to potentially call the moon or Mars 'home' for extended periods of.....»»

Transcriptional regulatory mechanism of plant pectin biosynthesis
Pectin is a complex cell wall polysaccharide. It plays an important role in modulating cell adhesion, cell morphogenesis and growth......»»
Nanobubbles provide pathway to build better medical devices
Researchers from the University of Sydney Nano Institute and School of Chemistry have revealed that tiny gas bubbles—nanobubbles just 100 billionths of a meter high—form on surfaces in unexpected situations, providing a new way to reduce drag in.....»»
Industry watch: Metaverse, the virtual-real integration
MediaTek's chairman Ming-Kai Tsai recently elucidated his views on the metaverse business opportunity that has become a hot topic these days. Metaverse ignites a new business opportunity with diverse changes and infinite extensions. From the physical.....»»
A pathway emerges: Biologists describe structure and function of a heme transport and assembly machine
Researchers described for the first time the structure of a bifunctional protein, called CcsBA, that transports heme and attaches it to cytochromes. The study captured two conformational states of CcsBA, a bacterial and chloroplast protein, allowing.....»»
Novel transcription factor inhibits flavone and anthocyanin biosynthesis in chrysanthemum at high temperatures
Plant flavonoid accumulation is promoted by various environmental factors, including excess light, UV radiation, drought, and low temperatures. Increased flavonoid content helps plants to maintain normal growth and development by eliminating exces.....»»
A pathway emerges: Biologists describe structure and function of a heme transport and assembly machine
Heme is an essential part of the protein hemoglobin, which colors human blood red. Heme also is crucial for cytochrome proteins, which power the cell. Humans, animals, plants and bacteria all use heme......»»
Melatonin exacerbates asthma, study finds
Asthma sufferers generally find their condition gets worse at night. Now researchers may understand why. Melatonin, a sleep hormone that is sometimes prescribed to treat insomnia, exasperates the constriction of the bronchus -- the pathway that moves.....»»
Visualizing the propagation path of electromagnetic waves from space to ground
Using data on electromagnetic (EM) waves and plasma particles measured simultaneously via multiple satellites, an international collaborative research group has discovered the existence of invisible "propagation path" of EM waves and elucidated the m.....»»
Targeting the brain’s immune cells may help prevent or treat Alzheimer’s disease
A gene mutation linked to Alzheimer's disease alters a signaling pathway in certain immune cells of individuals with the disease, according to a new study. The team also found that blocking the pathway -- with a drug that's currently being tested in.....»»
Potential new therapeutic pathway to clear chronic viral infections
A recent study in mice has uncovered that during chronic viral infection, a protein called BMI-1 gets turned on too early in B cells and messes up the delicate balance of gene expression, resulting in antibodies that are unsuccessful in their endeavo.....»»
Cellular aging: A basic paradox elucidated
Cancer researchers show for the first time that cellular senescence, which occurs when aging cells stop dividing, is caused by irreversible damage to the genome rather than simply by telomere erosion......»»
Hunting for human obesity genes in fat fruit flies
Fruit flies provide an effective platform for screening new obesity genes, and fat flies implicate a neuronal signaling pathway in weight gain, according to a new study publishing November 4th in the open-access journal PLOS Biology by Sadaf Farooqi.....»»
Sweet! How glycogen is linked to heat generation in fat cells
Researchers describe how energy expenditure and heat production are regulated in obesity through a previously unknown cellular pathway......»»
Scientists uncover the genetic pathway that colors bumble bee stripes
While most people in the U.S. may think of bumble bees as the standard yellow and black variety, there are an estimated 260 bee species that sport about 400 different color patterns. One reason many people associate bumble bees with distinct colors i.....»»
3D structure of artificially designed protein nanoparticle TIP60 elucidated by cryo-electron microscopy
Nanoparticles and nanocages are attractive materials that may be applied in color agents, catalysts, and drug delivery. For real-world use, it is necessary to produce a large number of nanoparticles of uniform size and shape, but thus far, nanopartic.....»»
Structural biology: Mechanisms of novel anti-cancer drugs elucidated
Double-stranded breaks (DSBs) are among the most hazardous forms of DNA damage. The checkpoint protein kinase ATM plays a key role in the repair of DSBs. Many anti-tumor drugs act by inducing DSB formation, so inhibition of ATM should enhance the sen.....»»
