How cells select DNA damage repair pathways
DNA is well known as the blueprint of life, necessary for an organism to facilitate living processes. DNA can be damaged by various factors such as radical metabolites, radiation, and some toxic chemicals. As DNA is a molecule consisting of two stran.....»»
Saturday Citations: M87* lashes out; a deep sleep discovery; proposal to build a digital cell
I love it when researchers observe an extra-weird particle, and this week, scientists reported the observation of a particle that only has mass when it's moving in a single direction. Good enough! An ancient DNA analysis suggests that Neanderthals an.....»»
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.....»»
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......»»
New congressional report: “COVID-19 most likely emerged from a laboratory”

Noninvasive imaging method can penetrate deeper into living tissue
Metabolic imaging is a noninvasive method that enables clinicians and scientists to study living cells using laser light, which can help them assess disease progression and treatment responses......»»
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.....»»

As holiday shopping continues, Apple is running a fun promotion at Apple Stores this weekend. At select stores in San Francisco, Miami, Los Angeles, and New York City, live artists will be available to personal gift bags for Apple shoppers….....»»
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.....»»

Silje Halvorsen bends down and fills a plastic bottle with water from Gillsvannet lake, a sheltered bathing spot just outside the center of Kristiansand......»»
Gurman: Apple-designed 5G modem coming to 2025 iPhones will be worse than Qualcomm’s
Apple’s long-in-the-works project to build its own cellular modem is about to see the light of day. As multiple reports have indicated in the past, select 2025 iPhone models will carry the Apple 5G modem—but thanks to a new report, now we know it.....»»
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.....»»
Study identifies pathways to enforce First Nation-led cultural heritage protection
A new research collaboration between the K'ómoks First Nation and Simon Fraser University highlights how Indigenous cultural heritage policies can protect archaeological sites threatened by development, given inadequate provincial heritage protectio.....»»

Proposed wastewater release into Cape Cod Bay likely to remain for at least one month, study finds
Scientists at the Woods Hole Oceanographic Institution (WHOI) investigating the pathways of the proposed wastewater discharge from the Pilgrim Nuclear Power Station (PNPS) find it has a high probability of remaining in Cape Cod Bay for at least one m.....»»
New synthetic receptor expands cellular control options, including immune response and neurological signaling
A basic function of cells is that they act in response to their environments. It makes sense, then, that a goal of scientists is to control that process, making cells respond how they want to what they want......»»
