Some RNA molecules have unexpected sugar coating
In a surprise find, scientists have discovered sugar-coated RNA molecules decorating the surface of cells......»»
Chemists develop sustainable method to remove "forever chemicals" from water
Perfluoroalkyl substances (PFAS) are highly versatile chemicals. These fluorine-containing organic molecules are the reason why rain drops simply slide off outdoor jackets. They are used in the greaseproof coating of paper food packaging and are key.....»»
New discovery toward sugar origami
Researchers at the Max Planck Institute of Colloids and Interfaces (MPICI) have designed a carbohydrate sequence capable of folding into a stable secondary structure......»»
Researchers induce cancer cells to "commit suicide" with a self-produced bacterial toxin
For the first time in the world researchers at Tel Aviv University have encoded a toxin produced by bacteria into mRNA (messenger RNA) molecules and delivered these particles directly to cancer cells, causing the cells to produce the toxin—which ev.....»»
California beachgoers face an unexpected peril: Aggressive, biting sea lions
As Southern Californians prepare to flood local beaches in anticipation of the Fourth of July holiday and an oncoming heat wave, experts are warning beachgoers to be vigilant about a surprising hazard: biting sea lions......»»
Unraveling the super-complex structure of supercooled liquids
When cooled to their freezing point, most liquids become solids or crystallize. In other words, the molecules arrange themselves in a perfectly ordered fashion, which physicists call a crystal. Supercooled liquids are different; they do not form such.....»»
Transplantation of genome-edited iPS cells delivers therapeutic molecules in vivo
Induced pluripotent stem (iPS) cells have a great impact on biology and medicine, and they are expected to improve regenerative medicine. Since 2014, when a sheet of retinal pigment epithelial cells derived from iPS cells was transplanted into patien.....»»
NASA restores contact with Mars helicopter after nine weeks of silence
NASA has restored contact with its Mars helicopter after 63 days of silence. The communications dropout, however, wasn't unexpected......»»
New image from James Webb Space Telescope reveals astonishing Saturn and its rings
Get ready to be amazed by the latest James Webb Space Telescope (JWST) image. Saturn's iconic rings seem to glow eerily in this incredible infrared picture, which also unveils unexpected features in Saturn's atmosphere......»»
Complex organosulfur molecules on comet 67P: Evidence from Rosetta orbiter and the lab
The Rosetta orbiter spectrometer for ion and neutral analysis (ROSINA) instrument orbited comet 67P to revolutionize our understanding of cometary material composition. A key finding of the satellite was to explore the composition of comet 67P/Churyu.....»»
Chemists develop new method to create chiral structures
Some molecules exist in two forms, such that their structures and their mirror images are not superimposable, like our left and right hands. Called chirality, it is a property these molecules have due to their asymmetry. Chiral molecules tend to be o.....»»
New light-responsive carriers for intracellular substance delivery
Artificial lipid bilayer vesicle liposomes, also called proteoliposomes, are specialized systems capable of incorporating various molecules, such as chemicals and drugs. Their unique properties make them ideal carriers for delivering substances insid.....»»
Rainforest releases oxidized organic molecules that form aerosol particles in tropical free troposphere, study reveals
Molecular-level measurements at Chacaltaya, Bolivia revealed that oxidized organic molecules were linked to isoprene emissions from Amazon rainforests hundreds of kilometers away. This potentially plays a crucial role in new particle formation, shedd.....»»
James Webb detects important molecule in the stunning Orion nebula
The molecule, called methyl cation, is important for the development of the complex carbon-based molecules on which life depends......»»
Surface-enhanced vibrational circular dichroism for chiral mixture sensing
Chiral molecules can present different chemical properties. For applications like drug delivery and diagnosis, it is important to detect chiral signals in mixtures. Although electronic circular dichroism (ECD) spectroscopy has been reported many time.....»»
Was that actually a tsunami that hit Florida? Yes, but not the kind you think
An unexpected culprit toppled beach chairs along the sand at normally calm Clearwater Beach, Florida, last Wednesday. West Coast surfers might snicker at the cause, but the National Weather Service confirms the rare 4-foot (1.2 meter) wave was caused.....»»
The ThinkPad X1 Carbon Gen 11 is both faster and longer-lasting
The ThinkPad X1 Carbon Gen 11 received low-power CPUs that increase battery life, as expected. But the added and unexpected benefit is faster performance......»»
How changing our diet can have unexpected negative economic, social and environmental impacts
Switching to a healthier diet not only reduces your risk of disease, it also improves the sustainability of our food system. But eating healthier also has indirect consequences that can lead to unexpected economic, social and environmental side effec.....»»
Do hummingbirds drink alcohol? More often than you think
You may not realize it, but that backyard hummingbird feeder filled with sugar water is a natural experiment in fermentation—yeast settle in and turn some of the sugar into alcohol......»»
Liquid metal could turn everyday things like paper into smart objects
This futuristic new liquid metal coating can make ordinary objects extraordinary. Enlarge (credit: LEONELLO CALVETTI/SCIENCE PHOTO LIBRARY) While paper isn’t exactly a smart material, it someday could be if it is cover.....»»
Demonstrating the significance of individual molecules during mechanical stress in cells
The cells in our bodies are continuously exposed to mechanical forces that are either externally applied or generated by the cells themselves. Being able to respond to such mechanical stimuli is an indispensable prerequisite for a large number of bio.....»»
