Newly described species of dome-headed dinosaur may have sported bristly headgear
If you look at enough dinosaur fossils, you'll see that their skulls sport an amazing variety of bony ornaments, ranging from the horns of Triceratops and the mohawk-like crests of hadrosaurs to the bumps and knobs covering the head of Tyrannosaurus.....»»
Uncovering the mechanism of photoexcited nucleobases: Is decay fast or suppressed?
The nucleobase molecules carrying the genetic codes are the most important ingredients for life, but they are also very vulnerable. When the ultraviolet component in the sunlight irradiates these molecules, the electrons in the molecules will be exci.....»»
Fossil fragments shed light on a new spinosaurid dinosaur found in Spain
A dinosaur specimen from Castellón, Spain represents a new proposed species of spinosaurid, reports a paper published in Scientific Reports. The identification of a potential new species suggests that the Iberian peninsula may have been a diverse ar.....»»
Simulation tools drive the new generation of therapies based on gene silencing
Proteins are large, complex molecules that play many critical roles in the body and are produced following the instructions encoded in DNA. By reading their DNA letters, cells produce an intermediate RNA molecule that will give rise to the correspond.....»»
Machine learning helps researchers predict the density of states within organic molecules
Organic chemistry, the study of carbon-based molecules, underlies not only the science of living organisms, but is critical for many current and future technologies, such as organic light-emitting diode (OLED) displays. Understanding the electronic s.....»»
A predatory dinosaur from Brazil and its surprising anatomy
Irritator challengeri was a two-legged, meat-eating dinosaur, or more precisely—a spinosaurid. The knowledge of the species is based on the most complete fossil skull known from this group. With the aid of X-ray computed tomographs usually used in.....»»
Novel AI-based software enables quick and reliable imaging of proteins in cells
Electron cryo-tomography (cryo-ET) is emerging as a powerful technique to provide detailed 3D images of cellular environments and enclosed biomolecules. However, one of the challenges of the methodology is the identification of protein molecules in t.....»»
Porous crystals made from plant extracts purify water from pharmaceutical pollutants
Researchers from Stockholm University have developed porous crystals made from pomegranate extract to capture and degrade pharmaceutical molecules found in local municipal wastewater. The research is published in the scientific journal Nature Water......»»
Comprehensive analysis of single plant cells provides new insights into natural product biosynthesis
Plants are impressive in their diversity, but especially in the variety of metabolites they produce. Many plant natural products are highly complex molecules, such as the alkaloids vincristine and vinblastine, which are produced by the Madagascar per.....»»

How the ancient messengers cAMP and cGMP deliver their messages
Two highly similar molecules with essential but often contrasting signaling roles in most life forms exert their distinct effects through subtle differences in their bindings to their signaling partners, according to a new study led by researchers at.....»»
Reconstructing ancient bacterial genomes can revive previously unknown molecules, a potential source for new antibiotics
Microorganisms—in particular bacteria—are skillful chemists that can produce an impressive diversity of chemical compounds known as natural products. These metabolites provide the microbes major evolutionary advantages, such as allowing them to i.....»»
Scientists revive Stone Age molecules
Breakthroughs in ancient genome reconstruction and biotechnology are now revealing the rich molecular secrets of Paleolithic microorganisms. In a new study published in Science, a transdisciplinary team of researchers led by the Leibniz Institute for.....»»
Hunting for life"s building blocks at minus 250 degrees Celsius
Searching for life's building blocks light-years away is an important task of the James Webb Space Telescope. But how does it know what to look for? Ph.D. student Marina Gomes Rachid is offering a helping hand by mapping out molecules that could exis.....»»
Geekbench Listing Reveals Pixel 7a Performance Scores
The 7a has been spotted yet again, this time via a Geekbench listing. While Google’s I/O event is still set to take place just a week from now, the internet has wasted no time in digging up all the information it possibly can on the P.....»»
How are dinosaur tissues preserved in deep time?
Ever since Mary Schweitzer found soft, stretchy tissue in a T. rex fossil in 2004, scientists have been trying to come to grips with how some biological tissues and cells could preserve within ancient critters......»»
Scientists design new bio-inspired molecules to promote bone regeneration
People's ability to regenerate bones declines with age and is further decreased by diseases such as osteoporosis. To help the aging population, researchers are looking for new therapies that improve bone regeneration......»»
"Mirror-image" molecules pave new path for cancer drug discovery
Scripps Research scientists have developed a new strategy for identifying small molecules that can change the function of proteins, offering a promising path for discovering targeted drugs. In collaboration with scientists at other institutions, the.....»»
RNA folding may be key to potential new antiviral targets in HIV-1
Ribonucleic acid (RNA) folds into complex structures, which allow it to interact specifically with other molecules in the cell. In HIV-1, minute differences in RNA folding can be crucial in determining whether viral RNA is "packaged" and thus leads t.....»»
