Regulation of the genome affects its 3D structure
All the cells of an organism share the same DNA sequence, but their functions, shapes or even lifespans vary greatly. This happens because each cell "reads" different chapters of the genome, thus producing alternative sets of proteins and embarking o.....»»
Greening of Antartica shows how climate change affects the frozen continent
Plant growth is accelerating on the Antarctic Peninsula and nearby islands. When satellites first started peering down on the craggy, glaciated Antarctic Peninsula about 40 years.....»»
So You Can 3D Print a Steak Now—but Why on Earth Would You?
WIRED tried 3D-printed steaks that you can’t buy anywhere yet. But reducing food to a technological problem leaves a bitter taste, and delivers all the joy of licking a catering catalog......»»
Study suggests statistical "noise" affects perceived evolutionary rates
For decades, researchers have observed that rates of evolution seem to accelerate over short time periods—say five million years versus fifty million years. This broad pattern has suggested that "younger" groups of organisms, in evolutionary terms,.....»»
Scientists find plant-like behavior in human cells
A team of scientists from Monash University has solved the structure of a protein known as "LYCHOS," which can detect and regulate cell growth by sensing cholesterol levels in the body......»»
Ancient protein structure may have enabled early molecular evolution and diversification
In a finding that offers fresh insights into the early evolution of life on Earth, two RIKEN biologists have conducted lab experiments that have revealed a previously unknown protein fold, which is completely absent in modern proteins......»»
As Wildfires Rage, California’s Insurance Market Is in Crisis
Providers are offering fewer and fewer policies because of costlier climate-fueled fires, homeowners moving into riskier areas, and outdated regulation of the insurance industry......»»
Filament structure found to activate and regulate CRISPR-Cas "protein scissors"
CRISPR-Cas systems help to protect bacteria from viruses. Several different types of CRISPR-Cas defense systems are found in bacteria, which differ in their composition and functions. Among them, the most studied proteins today are Cas9 and Cas12, al.....»»
Ring Protect rebrands to Ring Home and adds 24/7 recording
Ring Protect is now Ring Home, and while its pricing structure is the same, it benefits from several cool new features -- including 24/7 recording......»»
Research provides new insights into role of mechanical forces in gene expression
The genome inside each of our cells is modeled by tension and torsion—due in part to the activity of proteins that compact, loop, wrap and untwist DNA—but scientists know little about how those forces affect the transcription of genes......»»
Seeing double: Designing drugs that target "twin" cancer proteins
Some proteins in the human body are easy to block with a drug; they have an obvious spot in their structure where a drug can fit, like a key in a lock. But other proteins are more difficult to target, with no clear drug-binding sites......»»
3D structure of key protein could advance development of hormone-free male contraceptive pill
Melbourne-based scientists behind the development of a hormone-free, reversible male contraceptive pill have, for the first time, solved the molecular structure of the discovery program's primary therapeutic target, significantly increasing the chanc.....»»
California governor vetoes expansive AI safety bill
Despite increasing calls for regulation, California Governor Gavin Newsom has vetoed the far reaching AI safety bill, SB 1047.....»»
Major AI bill vetoed by California governor, despite increased calls for regulation
California is home to many of the country’s largest AI innovators, including Apple. Today, they’re all breathing a sigh of relief. Governor Gavin Newsom has vetoed a major AI regulatory bill that came to his desk, while nonetheless highlighting t.....»»
Geologists discover mysterious subduction zone beneath Pacific, reshaping understanding of Earth"s interior
University of Maryland scientists uncovered evidence of an ancient seafloor that sank deep into Earth during the age of dinosaurs, challenging existing theories about Earth's interior structure. Located in the East Pacific Rise (a tectonic plate boun.....»»
Gambling marketing and the Premier League—the continued failure of industry self-regulation
New research reveals gambling messages during the opening weekend of this season's football Premier League have almost trebled since last year, putting fans including children at risk......»»
How climate change affects deer—experts draw findings from 20 years of research
Temperature, rainfall, snow and extreme weather events are all factors linked to climate change that directly affect wildlife. Understanding the impact of these factors on the physiology, population dynamics and distribution of different deer species.....»»
How a protein keeps gene clusters quiet in the cell nucleolus
In a discovery that sheds light on the complex mechanisms of gene regulation, scientists at EPFL have uncovered a critical role for the protein ZNF274 in keeping certain gene clusters turned off by anchoring them to the cell nucleolus. The study is p.....»»
New method enables noninvasive plant magnetic resonance imaging
The "omics" technologies—genomics, transcriptomics, proteomics, and metabolomics—are at the forefront of discovery in modern plant science and systems biology. In contrast to the rather static genome, however, the metabolome and the products meas.....»»
These 3D-printed pipes inspired by shark intestines outperform Tesla valves
Prototypes control fluid flow in a preferred direction with no need for moving parts. Enlarge / Shark intestines are naturally occurring Tesla valves; scientists have figured out how to mimic their unique structure. (credit: Sara.....»»
