Physical mechanisms explaining DNA and RNA twist changes
The double-helix structure of DNA is deformed by environmental stimuli, which will then affect gene expression, and eventually trigger a sequence of cellular processes. Recent research led by a physicist from City University of Hong Kong (CityU) obse.....»»
Don Cheadle hints that one troubled Marvel movie could redeem Secret Invasion’s biggest twist
Don Cheadle believes that Armor Wars has the power to redeem Secret Invasion's divisive Rhodey twist, but only if it... you know... actually gets made......»»
Chemists develop chiral DNA catalysts for asymmetric catalysis
Chemists from the National University of Singapore (NUS) have developed a way to make diverse chiral deoxyribonucleic acid (DNA) catalysts by merging DNA repair with biorthogonal chemistry, paving the way for more efficient and versatile approaches t.....»»
Hidden in the teeth: DNA study finds these 19th century lions preyed on humans and giraffes
In 1898, two male lions terrorized an encampment of bridge builders on the Tsavo River in Kenya. The lions, which were massive and maneless, crept into the camp at night, raided the tents and dragged off their victims. The infamous Tsavo "man-eaters".....»»
Lots to learn from at Maker Faire Bay Area
This article first appeared in the MakerEd.org newsletter. Describing what Maker Faire is to people who have never experienced it is difficult. I find pictures do a better job of explaining what it is than I can do with words. The core of Maker Fair.....»»
High-resolution structural data shows how a supercomplex links mRNA translation and decay
Messenger RNA (mRNA) serves as a blueprint for proteins. When mRNA is no longer needed, it must be degraded. Director Elena Conti and her team at the Max Planck Institute of Biochemistry in Martinsried near Munich have now been able to show that the.....»»
Astronomers find Webb data conflict with reionization models
Reionization is a critical period when the first stars and galaxies changed the physical structure of their surroundings, and eventually the entire universe. Established theories state that this epoch ended around 1 billion years after the Big Bang......»»
Key gene discovered for regulating rice grain length
Recently, a research team led by Professor Wu Yuejin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, discovered a key gene that can influence rice grain length by regulating cell proliferation, the RGL2 gene. This pr.....»»
Claustrophobic cells slow their own growth, forming beautiful patterns of concentric circles
Like so many organisms on the planet, when cells experience mosh-pit-level crowding, they may just become stressed. Yet unlike most other life forms, cells subject to physical stress from crowding by neighbors can find some relief by dramatically slo.....»»
Advanced model predicts gene architecture via nucleosome position
DNA—the molecule that carries the genetic information of all living organisms—is packaged within cells in a complex manner that allows it to function efficiently. Nucleosomes facilitate DNA compaction and also play a crucial role in regulating ge.....»»
The unintended consequences of brick-and-mortar"s decline
Lately, many big retail brands have been closing physical locations, in what has become known as the "retail apocalypse." Whether the stated reason is declining revenue, or concerns related to "shrinkage" and employee safety in some cities, the impac.....»»
Scientists explore whether smaller chromosomes lead to more segregation errors during egg cell division
Three RIKEN researchers have shed light on the cellular mechanisms underlying chromosomal abnormalities that can cause miscarriages and congenital disorders such as Down syndrome......»»
Researchers discover new isotope plutonium-227
A research team led by researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has synthesized a new plutonium isotope, plutonium-227. Their study is published in Physical Review C......»»
Using a unique combination of DNA techniques to authenticate ginseng supplements and combat adulteration
Rosalee Hellberg, an associate professor in Chapman University's Food Science Program, and her research team have made a significant breakthrough in the fight against adulteration in dietary supplements. Effective methods for identifying adulteration.....»»
Novel detection technology alerts health risks from TNT metabolites
Recently, a research group from the Hefei lnstitutes of Physical Science (HFIPS) of the Chinese Academy of Sciences developed an approach that can facilitate rapid detection of both positive and negative ions of four toxic metabolites derived from 2,.....»»
You get your energy from your mom. A new study explains why
It's one of the basic tenets of biology: We get our DNA from our mom and our dad. But one notable exception has perplexed scientists for decades: Most animals, including humans, inherit the DNA inside their mitochondria—the cell's energy centers—.....»»
Key molecule in wound healing identified through mapping of long non-coding RNA molecules
A new study from Karolinska Institutet and the Chinese Academy of Medical Sciences has identified an RNA molecule that is important for skin wound healing. The research, published in Nature Communications, may have implications for the treatment of h.....»»
Nanopore technique shows transport mechanism of chaperone proteins at the single-molecule level
Proteins control most of the body's functions, and their malfunction can have severe consequences, such as neurodegenerative diseases or cancer. Therefore, cells have mechanisms in place to control protein quality......»»

The critically acclaimed Apple original Severance is getting a release on disc, with a Blu-ray edition . more….....»»
Scientists explore geothermal energy potential in supercritical reservoirs
A team of EPFL scientists has provided insight into the mechanisms at work in geothermal reservoirs located deep underground, known as supercritical reservoirs. Through a combination of computer simulations and lab experiments, they showed that rocks.....»»
Cuffing season: An evolutionary explanation for why people want to settle down for the winter months
Does the effort you invest in seeking a romantic partner intensify as summer ends? During the colder, darker months, people have been known to engage in "cuffing season," which means attaching yourself to or having a physical relationship with someon.....»»
