Novel fluorescent materials developed for real-time visualization of multi-component solvents and temperature
Recently, a research team led by Professor Jiang Changlong at Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences, developed a new donor-acceptor (D-A) type fluorescent dye called AFL. This dye changes its fluorescence col.....»»
New technique points to unexpected uses for snoRNA across many cell types
Dynamic, reversible modifications of DNA and RNA regulate how genes are expressed and transcribed, which can influence cellular processes, disease development, and overall organismal health. Small nucleolar RNAs (snoRNAs) are a common but overlooked.....»»
Wealthy nations offer $250 bn on climate but pressed for more
Wealthy nations on Friday offered $250 billion a year to help poorer nations hit hardest by global warming but faced immediate calls led by Africa to give more as UN climate negotiations extended into overtime......»»
Using light to create bioelectronics inside living organisms
Bioelectronics research and development of implants made of electrically conductive materials for disease treatment is advancing rapidly. However, bioelectronic treatment is not without complications. Researchers at Lund University in Sweden have tak.....»»
tRNAs help some mRNAs get lost in translation
Scientists have discovered that tRNAs can determine how long mRNAs exist in a cell, causing some messages to be stabilized and translated into more protein, while directing others to be degraded and limiting how much protein can be made. They publis.....»»
Engineers refine lipid nanoparticles for better mRNA therapies
Penn Engineers have cooked up a new way to improve mRNA delivery, developing an optimal "recipe" for ionizable lipids—key ingredients in lipid nanoparticles (LNPs), the molecules behind the COVID-19 vaccines and other innovative therapies. The meth.....»»
AI and genus-conditioned algorithms create precise simulation-ready models of 600,000 existing urban trees
The Irish philosopher George Berkely, best known for his theory of immaterialism, once famously mused, "If a tree falls in a forest and no one is around to hear it, does it make a sound?" What about AI-generated trees? They probably wouldn't make a s.....»»
Study reveals RNA"s unknown role in DNA damage repair
A multi-institutional team of researchers, led by Georgia Tech's Francesca Storici, has discovered a previously unknown role for RNA. Their insights could lead to improved treatments for diseases like cancer and neurodegenerative disorders while chan.....»»
Video: Our sun is the star in a new simulation
NASA supercomputers are shedding light on what causes some of the sun's most complex behaviors. Using data from the suite of active sun-watching spacecraft currently observing the star at the heart of our solar system, researchers can explore solar d.....»»
Introducing "UFO" galaxies—the Milky Way"s dustier cousins
In a new study, a team of astrophysicists led by CU Boulder has set out to unravel the mysteries of UFOs—not the alien spacecraft, but a class of unusually large and red galaxies that researchers have nicknamed Ultra-red Flattened Objects, or UFOs.....»»
Durable supramolecular plastic is fully ocean-degradable and doesn"t generate microplastics
Researchers led by Takuzo Aida at the RIKEN Center for Emergent Matter Science (CEMS) have developed a new durable plastic that won't pollute our oceans. The new material is as strong as conventional plastics and biodegradable, but what makes it spec.....»»
Spatial interactomics tool maps protein interactions to fight lung cancer
As Ahmet F. Coskun and his team of researchers continue their mission to create a 3D atlas of the human body, mapping cells and tissues, they're making discoveries that could lead to better treatments for the most common type of lung cancer......»»
How anti-obesity drugs are linked to food waste: 1 in 4 users report an increase in discarding food
Taking anti-obesity drugs has led some U.S. adults to throw away more food than they tossed before starting the medications, a new study has found......»»
Chemists create world"s thinnest spaghetti
The world's thinnest spaghetti, about 200 times thinner than a human hair, has been created by a UCL-led research team. The spaghetti is not intended to be a new food but was created because of the wide-ranging uses that extremely thin strands of mat.....»»
