Digging into the molecules of fossilized dinosaur eggshells
Dinosaurs roamed the Earth more than 65 million years ago, and paleontologists and amateur fossil hunters are still unearthing traces of them today. The minerals in fossilized eggs and shell fragments provide snapshots into these creatures' early liv.....»»
Efficient fuel-molecule sieving using graphene
A research team led by the University of Tsukuba has successfully developed a new method that can prevent the crossover of large fuel molecules and suppress the degradation of electrodes in advanced fuel cell technology using methanol or formic acid......»»
Machine-learning-boosted drug discovery with 10-fold time reduction
Boosting virtual screening with machine learning allowed for a 10-fold time reduction in the processing of 1.56 billion drug-like molecules. Researchers from the University of Eastern Finland teamed up with industry and supercomputers to carry out on.....»»
Diamond materials as solar-powered electrodes: Spectroscopy shows what"s important
It sounds like magic: photoelectrodes could convert the greenhouse gas CO2 back into methanol or N2 molecules into valuable fertilizer—using only the energy of sunlight......»»
Using harmless light to change azobenzene molecules with new supramolecular complex
Azobenzenes are incredibly versatile and have many potential uses, such as in making tiny machines and improving technology as well as making light controllable drugs. This molecule can switch between two different forms by light. However, the two fo.....»»
Researchers develop first method to study microRNA activity in single cells
MicroRNAs are small molecules that regulate gene activity by binding to and destroying RNAs produced by the genes. More than 60% of all human genes are estimated to be regulated by microRNAs; therefore, it is not surprising that these small molecules.....»»
Team resolves molecular switching behavior of azonium compounds for light-controlled drugs
Molecules that change shape under the influence of light can be used as switches in biomedical applications, for instance to inhibit an enzyme. An international team of researchers, including chemists at the Universities of Amsterdam and Groningen, h.....»»
Dinosaur feathers reveal traces of ancient proteins
Paleontologists at University College Cork (UCC) in Ireland have discovered X-ray evidence of proteins in fossil feathers that sheds new light on feather evolution......»»
Experiments on fossilized insects help reveal their true colors
A team of paleontologists and ecological scientists from Nanjing University, the Chinese Academy of Sciences and University College Cork, has found that it might be possible to estimate coloration for some fossilized insects using a new technique. In.....»»
RNA has been recovered from an extinct species for the first time
A new study shows the isolation and sequencing of more than a century-old RNA molecules from a Tasmanian tiger specimen preserved at room temperature in a museum collection. This resulted in the reconstruction of skin and skeletal muscle transcriptom.....»»
Molecular properties are only weakly correlated, study finds
The number of molecules thought to exist is unfathomably large—somewhere between 1050 and 1060 (for comparison, there are only 1022 to 1024 stars in the observable universe). The chemical and pharmaceutical sciences have sought a comprehensive unde.....»»
Precisely arranging nanoparticles to develop plasmonic molecules
In the incredibly small world of molecules, the elementary building blocks—the atoms—join together in a very regular pattern. In contrast, in the macroscopic world with its larger particles, there is much greater disorder when particles connect......»»
Scientists show how the signaling molecules BMP and FGF guide cell differentiation during embryonic development
Bricklayer, banker, teacher—choosing a career is one of the most exciting and important decisions in our lives. At the beginning of embryonic development, our cells are also faced with this decision. Some of them become blood cells, others muscle c.....»»
A mysterious blue molecule will help make better use of light energy
Researchers at IOCB Prague are the first to describe the causes of the behavior of one of the fundamental aromatic molecules, which fascinates the scientific world not only with its blue color but also with other unusual properties—azulene. Their c.....»»
Flowering plants survived the dinosaur-killing asteroid—and may outlive us
If you looked up 66 million years ago you might have seen, for a split second, a bright light as a mountain-sized asteroid burned through the atmosphere and smashed into Earth. It was springtime and the literal end of an era, the Mesozoic......»»
Researchers: If neutron stars have mountains, they should generate gravitational waves
A neutron star is 2 solar masses compressed into a ball only 12 kilometers wide. Its surface gravity is so immense it compresses atoms and molecules into raw nuclei and squeezes electrons into protons transforming them into neutrons. Given such immen.....»»
"Crappier-than-crap" molecule exposed in overhaul of carbon-nitrogen-hydrogen chemistry
Russian researchers have explained why scientists studying crude oil and celestial chemistry—as well as certain down-to-earth matters—frequently come across some molecules incorporating carbon, nitrogen, and hydrogen but not other combinations of.....»»
The Samsung Galaxy Ring is starting to look like a sure thing
Further digging has revealed an icon of what appears to be a ring, indicating that Samsung could be working on a Galaxy Ring. The post The Samsung Galaxy Ring is starting to look like a sure thing appeared first on Phandroid. There have be.....»»
Butt-dial of iPhone Emergency SOS via satellite still summons helicopter rescue
While enjoying a trip through Dinosaur National Monument, one hiker found himself the subject of a helicopter search-and-rescue mission after falsely activating his iPhone's Emergency SOS via satellite feature.The different stages of using Emergency.....»»
New research signals a quantum leap for brain tumor treatment
Researchers have discovered a new way to target and kill cancer cells in hard-to-treat brain tumors using electrically charged molecules to trigger self-destruction, which could be developed into a spray treatment used during surgery......»»
Pollen in pee: Fossilized urine from a small African mammal helps with understanding past environments
If you are allergic to pollen, you are likely to curse the existence of these microscopic particles. You're not alone: up to 30% of the world's population suffers from hay fever, which is often driven by pollen allergies. Shifting global climates are.....»»
