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.....»»
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.....»»
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.....»»
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.....»»
Early Human Ancestors Ate Each Other for Food, Fossil Leg Bone Suggests
A fossilized hominin leg shows gashes that were probably made by stone tools.....»»
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.....»»

Newly identified theropod dinosaur had strange hands
A team of archaeologists and paleontologists affiliated with several institutions in China, working with a colleague from Italy, has identified a new species of theropod dinosaur with strange hand features. In their paper published in the journal Cre.....»»
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.....»»
To Save the Planet, Start Digging

Nothing’s USB-C charging cable is actually really cool and we’re totally digging it
Nothing’s CEO Carl Pei has shared an image on Twitter, giving us a look at the company’s upcoming USB-C charging cable which honestly looks kind of cool. There are so many phones being released these days that sometimes they all kind.....»»
Protective molecules facilitate molybdate anion binding to create novel silver nanoclusters
Silver nanocluster synthesis, or the binding of a silver atom to negatively charged anions, is often plagued by stability, sizing uniformity and surface composition issues. Protective molecules that bind the surface of silver nanoclusters, called lig.....»»
Remains of new species of duck-billed dinosaur found in Chile
Remains of a species of herbivorous dinosaur previously unknown in the southern hemisphere have been discovered in Chile, challenging long-held beliefs about the range of duck-billed dinosaurs, scientists said Friday......»»
