Signaling pathway discovery could lead to faster, more reliable human stem cell differentiation
A recent discovery has found a possible avenue to improve human health by better understanding how to engineer human stem cell differentiation......»»
Tweaking non-neural brain cells can cause memories to fade
Neurons and a second cell type called an astrocyte collaborate to hold memories. “If we go back to the early 1900s, this is when the idea was first proposed that memories are ph.....»»
Caste differentiation in ants: How a specific hormone regulates the process
Scientists from the University of Copenhagen have revealed how a specific hormone regulates ant caste differentiation by phenotypic measurements of organ-level developmental changes and matching transcriptome analyses. Published in the Proceedings of.....»»
Characterizing shifts in Sicily"s seasonal rainfall
Around the world, man-made climate change is increasing both the frequency and severity of extreme weather events. Seasonal patterns in rainfall are an especially important indicator of these changes: While a lack of rain can lead to more severe drou.....»»
On the trail of an 18th-century master forger: New evidence discovered
A document held in Göttingen University's Faculty of Humanities has been revealed as an 18th century forgery. The document purports to be from 1266, but mentions a church in Pisa that was not built until later. This discovery is the result of resear.....»»

Niagara fireball event leads to discovery of tiniest known asteroid
In an international study led by Western University and Lowell Observatory, scientists describe a pioneering, integrative approach for studying near-Earth asteroids based largely on a November 2022 fireball event that dropped meteorites in the Niagar.....»»
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.....»»
Fossil discovery reveals giant worm lizard with snail-cracking jaws
An international team of researchers has discovered a new fossil worm lizard species in Tunisia. Terastiodontosaurus marcelosanchezi is the largest known species of the Amphisbaenia group, with a skull length of over five centimeters......»»
Discovery of van Hove singularities could lead to novel materials with desirable quantum properties
Strong interactions between subatomic particles like electrons occur when they are at a specific energy level known as the van Hove singularity. These interactions give rise to unusual properties in quantum materials, such as superconductivity at hig.....»»
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.....»»
Ryugu asteroid sample rapidly colonized by terrestrial life despite strict contamination control
Panspermia is the hypothesis that life can survive the transfer between planetary bodies as a secondary path for life to get started on planets throughout a solar system. The discovery of extraterrestrial life on asteroids or within meteorites would.....»»
Low levels of common contaminants but high levels of other elements in waters linked to abandoned lithium mine
Lithium ore and mining waste from a historic lithium mine located west of Charlotte, North Carolina, are unlikely to contaminate surrounding waters with common pollutants such as arsenic and lead, according to a new study......»»
"Genetic time machine" reveals complex chimpanzee cultures
In recent decades, scientists have clearly demonstrated that chimpanzees, like humans, pass on complex cultures such as tool use from generation to generation. But human culture has become vastly more sophisticated, from the Stone Age to the Space Ag.....»»
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.....»»
FCC chairwoman announces departure, paving way for Republican majority
Rosenworcel had to lead agency without Democratic majority for most of her term. Federal Communications Commission Chairwoman Jessica Rosenworcel announced today that she will lea.....»»
Researchers investigate health risks of potentially toxic elements in surface water in Tarim River Basin, China
Potentially toxic elements (PTEs) in surface water in arid areas can pose a serious threat to natural environment and human health......»»
Oldies but goodies: Study shows why elderly animals offer crucial scientific insights
A new study on aging in the animal kingdom has highlighted how urgently Earth's oldest and wisest creatures must be protected, with knowledge and environmental stability lost due to human intervention......»»
AI tool can engineer "better, faster, stronger" proteins
Nature is adept at designing proteins. Scientists are even better. But artificial intelligence holds the promise of improving proteins many times over. Medical applications for such "designer proteins" range from creating more precise antibodies for.....»»
Origin of life research finds RNA can favor both left- and right-handed proteins
The mystery of why life uses molecules with specific orientations has deepened with a discovery that RNA—a key molecule thought to have potentially held the instructions for life before DNA emerged—can favor making the building blocks of proteins.....»»
Math-selective US universities reduce gender gap in STEM fields, analysis finds
Nationally, men in colleges and universities currently outpace women in earning physics, engineering, and computer science (PECS) degrees by an approximate ratio of 4:1. To better understand the factors driving these gaps, NYU researchers analyzed ba.....»»
