Saturday Citations: On chimpanzee playwrights; the nature of dark energy; deep-diving Antarctic seals
This week, researchers reported the world's second-tiniest toad, winning the silver in the Brachycephalus contest. Chemists at UCLA disproved a 100-year-old organic chemistry rule. And researchers in Kenya report that elephants don't like bees, which.....»»
Fungi may not think, but they can communicate
Fungi form distinct networks depending on how food sources are arranged. Fungi can be enigmatic organisms. Mushrooms or other structures may be visible above the soil, but beneath.....»»
Chiral molecular self-assemblies that absorb light boost singlet fission process, research demonstrates
In organic molecules, an exciton is a particle bound pair of an electron (negative charge) and its hole (positive charge). They are held together by Coulombic attraction and can move within molecular assemblies. Singlet fission (SF) is a process wher.....»»
Chemists just broke a 100-year-old rule and say it"s time to rewrite the textbooks
UCLA chemists have found a big problem with a fundamental rule of organic chemistry that has been around for 100 years—it's just not true. And they say, It's time to rewrite the textbooks......»»
Safe, efficient method for synthesizing allenes opens up new possibilities for drug development
A research team jointly led by Professor Sung You Hong and Professor Jan-Uwe Rohde has unveiled a novel method for synthesizing allenes—a series of compounds integral to drug development and synthetic chemistry—without relying on hazardous, highl.....»»
International team discovers small molecules that regulate how fast plant leaves age
Two small molecules that are produced by the plant Arabidopsis thaliana are shown to have the opposite effect on how fast its leaves age. The molecules are peptides, short chains of amino acids. While the peptide SCOOP10 accelerates aging, SCOOP12 su.....»»
Single-molecule tracking technology streamlines drug discovery
New drug discovery is a critical step for improving patients' lives. First, researchers must identify molecules in the body's cells that help drive disease, as these are potential targets for new drugs. The next step is to screen candidate drugs that.....»»

Novel polypeptide-based molecules could pave the way for enhanced polymer design
A research study describes a systematic high-throughput design approach for virtual screening and creation of novel polypeptide-based molecules that form regular secondary structures that can be used in biology or materials science research. The stud.....»»
Researchers observe stick-slip phenomenon in carbon nanotube fibers
The shapes of simple polyatomic molecules such as carbon dioxide and methane are characterized by a specific symmetry depending on the manner of linking of the atoms. Nano- to micrometer-sized particles that mimic the shapes of such polyatomic molecu.....»»
Bones from shipwreck suggest right- or left-handedness could affect how clavicle chemistry changes with age
A new study of human skeletal remains from the wreck of the 16th century English warship "Mary Rose" suggests that whether a person is right- versus left-handed may influence how their clavicle bone chemistry changes as they age. Dr. Sheona Shankland.....»»
AI training method can drastically shorten time for calculations in quantum mechanics
The close relationship between AI and highly complicated scientific computing can be seen in the fact that both the 2024 Nobel Prizes in Physics and Chemistry were awarded to scientists for devising AI for their respective fields of study. KAIST rese.....»»
Scientists provide direct evidence of breakdown of spin statistics in ion-atom charge exchange collisions
Since the first X-ray image of a comet was reported using an X-ray telescope in 1996, the investigation of charge exchange in collisions between highly charged ions and atoms or molecules has emerged as a hot research topic......»»
