Observing mammalian cells with superfast soft X-rays
Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or quadrillionths of a second......»»
Observing ultrafast photoinduced dynamics in a halogen-bonded supramolecular system
Researchers have uncovered how the halogen bond can be exploited to direct sequential dynamics in multi-functional crystals, offering crucial insights for developing ultrafast-response times for multilevel optical storage......»»
Molecular stop signal identified: The surveillance system of cell division
Several million cells divide every second in our bodies. During nuclear division (mitosis), the genetic material must be distributed correctly and completely between the daughter cells—errors in this process can lead to defective developments or ge.....»»
NASA"s Hubble Space Telescope temporarily pauses observations after malfunction
The Hubble Space Telescope has temporarily stopped observing the cosmos......»»
New method for safe and efficient cell transfection developed by researchers
Transfection is the process of deliberately introducing nucleic acids into cells. Cell transfection is crucial in the fields of T cell and stem cell therapy. However, the existing transfection technology still faces challenges in achieving high effic.....»»
How can we make good decisions by observing others? A videogame and computational model have the answer
How can disaster response teams benefit from understanding how people most efficiently pick strawberries together, or how they choose the perfect ice cream shop with friends?.....»»
New mathematical framework sheds light on how cells communicate to form an embryo
Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called self-organization, as seen in a school of fish or a flock of b.....»»
A new way to see viruses in action: Super-resolution microscopy provides a nano-scale look
A new, nano-scale look at how the SARS-CoV-2 virus replicates in cells may offer greater precision in drug development, a Stanford University team reports in Nature Communications. Using advanced microscopy techniques, the researchers produced what m.....»»
Q&A: How to make sustainable products faster with artificial intelligence and automation
By modifying the genomes of plants and microorganisms, synthetic biologists can design biological systems that meet a specification, such as producing valuable chemical compounds, making bacteria sensitive to light, or programming bacterial cells to.....»»
Scientists develop most sensitive method yet for observing single molecules
Scientists at the University of Wisconsin–Madison have developed the most sensitive method yet for detecting and profiling a single molecule—unlocking a new tool that holds potential for better understanding how the building blocks of matter inte.....»»
New modified CRISPR protein can fit inside virus used for gene therapy
Researchers have developed a novel version of a key CRISPR gene-editing protein that shows efficient editing activity and is small enough to be packaged within a non-pathogenic virus that can deliver it to target cells. Hongjian Wang and colleagues a.....»»
Is your coffee "not hot" or "cold"? Observing how the brain processes negated adjectives
Negating an adjective by placing 'not' in front of it affects the way our brains interpret its meaning, mitigating but not entirely inverting our interpretation of its definition. In a study published in the open-access journal PLOS Biology, Arianna.....»»
Chandra X-ray Observatory"s clear, sharp photos help astrophysicist study energetic black holes
When a star is born or dies, or when any other very energetic phenomenon occurs in the universe, it emits X-rays, which are high-energy light particles that aren't visible to the naked eye. These X-rays are the same kind that doctors use to take pict.....»»
It"s hard to find fossil skin, but a rare discovery reveals clues about the evolution from water to land
Fossilized skin and other soft tissues are exceedingly rare, and it is only under special conditions that these rarest of fossils are preserved......»»
New approach uses "cloaked" proteins to deliver cancer-killing therapeutics into cells
An interdisciplinary collaboration has designed a way to "cloak" proteins so that they can be captured by lipid nanoparticles, which are akin to tiny bubbles of fat. These bubbles are small enough to sneak their hidden cargo into living cells, where.....»»
A change of direction: Research reveals a new method to manipulate cell movement in embryos
As embryos grow from conception to birth, cells multiply rapidly and move in a highly organized manner to create the skeleton, organs and other crucial systems. But how do cells know to move in precisely the right direction at the right time to creat.....»»
Philippines deploys river rangers in battle against plastic
Using a long-handled net, Ronnel Narvas scoops up discarded plastic soft drink bottles, shopping bags and palm-sized sachets as he wades through a foul-smelling tributary in the Philippine capital Manila......»»
Animals self-medicate with plants—a behavior people have observed and emulated for millennia
When a wild orangutan in Sumatra recently suffered a facial wound, apparently after fighting with another male, he did something that caught the attention of the scientists observing him......»»
Researchers reveal how acetylation regulates centromere dynamics, chromosome segregation and mitotic progression
Cell division produces new cells, which underpin life proliferation and development. Mitosis is the shortest and the most dynamic phase of the cell cycle. During mitosis, chromosomes are evenly distributed between the two daughter cells, preserving t.....»»
