A new twist: The molecular machines that loop chromosomes also twist DNA
Scientists from the Kavli Institute of Delft University of Technology and the IMP Vienna Biocenter have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor protei.....»»

Neanderthal-human interbreeding lasted 7,000 years, new study reveals
A new analysis of DNA from ancient modern humans (Homo sapiens) in Europe and Asia has determined, more precisely than ever, the time period during which Neanderthals interbred with modern humans, starting about 50,500 years ago and lasting about 7,0.....»»
Ancient genomes link early Europeans to Neanderthal ancestry
After modern humans left Africa, they met and interbred with Neanderthals, resulting in around 2–3% Neanderthal DNA that can be found in the genomes of all people outside Africa today. However, little is known about the genetics of these first pion.....»»
Studies pin down exactly when humans and Neanderthals swapped DNA
We may owe our tiny sliver of Neanderthal DNA to just a couple of hundred Neanderthals. Two recent studies suggest that the gene flow (as the young people call it these days) betw.....»»
New model find molecular interactions key to creating order in active systems
Non-reciprocal interactions can increase the order in an active system. This is the finding of a study by scientists from the department of Living Matter Physics at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS)......»»
Counting Uganda"s lions: We found that wildlife rangers do a better job than machines
Lions are a symbol of Africa's last wild places. It's a species central to many of the continent's cultures and religions. But lion populations have reportedly declined over the past 50 years, especially in parts of west and east Africa......»»
How a piece of plastic shut down DNA testing at crime lab
It was technically a successful scientific discovery when analysts at the Hennepin County, Minnesota, forensic science lab recognized there was a contaminant somewhere in its DNA process. That did not lessen the sense of dread......»»
Watch this festive drone display that scored a world record
A recent drone display used thousands of the machines to create festive scenes, with one particular image earning its creators a place in the record books......»»
Fast, rewritable computing with DNA origami registers
DNA stores the instructions for life and, along with enzymes and other molecules, computes everything from hair color to risk of developing diseases. Harnessing that prowess and immense storage capacity could lead to DNA-based computers that are fast.....»»
Rethinking the quantum chip: Engineers present new design for superconducting quantum processor
Researchers at the UChicago Pritzker School of Molecular Engineering (UChicago PME) have realized a new design for a superconducting quantum processor, aiming at a potential architecture for the large-scale, durable devices the quantum revolution dem.....»»
Ultrafast electron imaging captures never-before-seen nuclear motions in hydrocarbon molecules excited by light
The interactions between light and nitroaromatic hydrocarbon molecules have important implications for chemical processes in our atmosphere that can lead to smog and pollution. However, changes in molecular geometry due to interactions with light can.....»»
The Talos Principle: Reawakened adds new engine, looks, and content to a classic
The game that was asking lots of questions about AI ethics 10 years ago is back. Are humans just squishy machines? Can an artificially intelligent robot create a true moral compas.....»»

Not so simple machines: Cracking the code for materials that can learn
It's easy to think that machine learning is a completely digital phenomenon, made possible by computers and algorithms that can mimic brain-like behaviors. But the first machines were analog and now, a small but growing body of research is showing th.....»»
Computer modeling shows close encounters between distant DNA regions cause bursts of gene activity
Researchers at Kyushu University have revealed how spatial distance between specific regions of DNA is linked to bursts of gene activity. Using advanced cell imaging techniques and computer modeling, the researchers showed that the folding and moveme.....»»
Finding traces of fish with DNA from water samples
Silje Halvorsen bends down and fills a plastic bottle with water from Gillsvannet lake, a sheltered bathing spot just outside the center of Kristiansand......»»
Experiments provide evidence that interaction of light with a hydrocarbon molecule produces strained molecular rings
When molecules interact with ultraviolet (UV) light, they can change shape quickly, producing strain—stress in a molecule's chemical structure due to an increase in the molecule's internal energy. These processes typically take just tens of picosec.....»»
Historical outbreaks of coffee wilt disease linked to gene transfer from another fungus
The fungus that causes coffee wilt disease repeatedly took up segments of DNA from a related fungal pathogen, which contributed to successive outbreaks of the disease. Lily Peck of Imperial College London, U.K., reports these new findings in a study.....»»
Spectroscopy and AI method provide unique window into protein structure and mechanism of action
The lab of Hassane Mchaourab, director of the Center for Applied Artificial Intelligence in Protein Dynamics and professor of molecular physiology and biophysics, has developed a methodological blueprint that couples experimental double electron–el.....»»
The return of Steam Machines? Valve rolls out new “Powered by SteamOS” branding.
