Genetically encoded biosensors measure living cells" charge in real time
Biological cells have many vital functions in the organism. For example, they produce proteins, carbohydrates and fats. But they are also responsible for detoxifying harmful molecules and transmitting signals and immune defense steps. A so-called red.....»»
Scientists steer the development of stem cells to regenerate and repair organs
Investigators from Cedars-Sinai and the University of California, San Francisco (UCSF) have identified a new way to deliver instructions that tell stem cells to grow into specific bodily structures, a critical step in eventually regenerating and repa.....»»
Programming cells: New RNA tool enhances precision in synthetic genetic circuits
Researchers have successfully developed a modular synthetic translational coupling element (SynTCE), significantly enhancing the precision and integration density of genetic circuits in synthetic biology. Their study was recently published in the jou.....»»
Molecular tool demonstrates how bad eggs are identified for destruction by reproductive system
The biological factory that produces reproductive cells has a robust quality control system to identify and eliminate eggs with chromosomal abnormalities. For years, cell biologists have sought to uncover the mechanisms behind this system, relying on.....»»
Molecular gardening: New enzymes discovered for protein modification pruning
Deubiquitinases (DUBs) are enzymes used by cells to trim protein modifications made from the protein ubiquitin, and thereby regulate proteins. Malfunctioning of DUBs could lead to diseases, including cancer and neurodegenerative disorders......»»
Uncovering a centaur"s tracks: Scientists examine unique asteroid-comet hybrid
Although our solar system is billions of years old, we've only recently become better acquainted with one of its more dynamic and captivating inhabitants known as (2060) Chiron......»»
Building a backbone: Scientists recreate the body"s "GPS system" in the lab
Scientists at the Francis Crick Institute have generated human stem cell models which, for the first time, contain notochord—a tissue in the developing embryo that acts like a navigation system, directing cells where to build the spine and nervous.....»»
Brain cells mature faster in space but stay healthy: ISS study
Microgravity is known to alter the muscles, bones, the immune system and cognition, but little is known about its specific impact on the brain. To discover how brain cells respond to microgravity, Scripps Research scientists, in collaboration with th.....»»
Unlocking the brain: Peptide-guided nanoparticles deliver mRNA to neurons
Penn Engineers have modified lipid nanoparticles (LNPs)—the revolutionary technology behind the COVID-19 mRNA vaccines—to not only cross the blood-brain barrier (BBB) but also to target specific types of cells, including neurons. This breakthroug.....»»
What is a dark comet? A quick guide to the "new" kids in the solar system
In 2017, NASA discovered and later confirmed the first interstellar object to enter our solar system......»»
Analysis: Apple not likely to enter the foldable market before 2027
Despite a seeming lack of consumer interest, Apple continues to plow ahead in researching future foldable iPhones, iPads, and Macs that could see the light of day as soon as late 2026.If Apple can develop a durable folding iPhone, it could take that.....»»
iOS 18.2’s new Mail app is nice, but I disabled one of its main features
With iOS 18.2, Apple introduced an all new Mail app. It introduced mail categorization, a fresh coat of paint, contact photos/business logos for conversations, a new system for grouping emails, and more. All of that sounded nice when it was unveiled.....»»
Uncovering the evolutionary origins of the hepatitis E virus
An international team of virologists, mammalian ecologists and zoologists has uncovered the evolutionary origins of the hepatitis E virus. In their study, published in the Proceedings of the National Academy of Sciences, the group analyzed genomic da.....»»
NASA’s boss-to-be proclaims we’re about to enter an “age of experimentation”
"You can get into a rhythm of using all of these providers to get things up very quickly." ORLANDO, Florida—On Wednesday, Jared Isaacman made his first public appearance since h.....»»
When do dogs enter old age? New study provides answers
A new study from the University of Liverpool has pinpointed the average age when dogs are considered by vets to be in "old age," providing insights that can help owners prepare for their pets' senior years......»»
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......»»
Geneticists have finally solved the mystery of Garfield"s orange coat
Garfield, star of the eponymous comic strip created by Jim Davis in 1978, is, like many of the cats that roam our homes, orange. He is orange in the same way that some people are redheaded, some horses are brown, or some dogs are Irish setters, but t.....»»
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......»»
Discovery of molecular switch explains how bacteria control their protein biosynthesis through cell metabolism
