Phys.org / Your body is full of medicine. Researchers can now synthesize it
Northeastern University researchers have made a breakthrough drug discovery, developing the first synthetic endogenous cannabinoid compound, with repercussions for new therapeutics from pain and inflammation to cancer.
Phys.org / The dinosaurs that forgot how to fly
A new study led by a researcher from the School of Zoology and the Steinhardt Museum of Natural History at Tel Aviv University examined dinosaur fossils preserved with their feathers and found that these dinosaurs had lost ...
Phys.org / Signature of climate change: Nearly half of harmful wildfire smoke exposure linked to human-caused warming
Across the western U.S., wildfires and the dangerous smoke that results have increased in frequency and intensity since the 1990s—that much is clear. Surprisingly less clear are the exact reasons why: While greenhouse gas-related ...
Phys.org / Scientists discover how plant cell walls guide stem cells
Imagine if our bodies could grow new organs throughout our entire lives. Plants do this constantly, thanks to tiny, powerful reservoirs of stem cells. But how do these cells know when to divide, and how do they ensure each ...
Phys.org / Ocean sediments are key to survival of northeastern US salt marshes
Salt marshes, those critical habitats that protect coastal towns from flooding, store massive amounts of blue carbon, support fisheries and play a key role in ecological resilience, are struggling to survive as oceans rise ...
Phys.org / Vital intertwining: Blood parasite's chainmail-like DNA structure could inspire next-generation materials
As tough as medieval chainmail armor and as soft as a contact lens. This material is not taken from science fiction, it is a natural structure made of thousands of DNA circles interlinked with each other. Studying it can ...
Phys.org / Dazzling cosmic jet reveals time-stamped history of star birth
An international team of astronomers has uncovered the most unmistakable evidence yet that the powerful jets launched by newborn stars reliably record a star's most violent growth episodes, confirming a long-standing model ...
Phys.org / For certain life-essential proteins in E. coli, repair is more likely
Proteins need to fold into specific shapes to perform their functions in cells, but they occasionally misfold, which can prevent them from properly functioning and even lead to disease.
Phys.org / Opposing forces in cells could hold clues to treating disease
A newly revealed molecular tug-of-war may have implications for better understanding how a multitude of diseases and disorders—including cancers, neurodegenerative diseases and immune disorders—originate, as well as how ...
Phys.org / New method enables precise fluorine addition to drug-like molecules in one step
Fluorine is critical for biomedicine. This element can help drug compounds be more potent and last longer in the body, and its radioactive isotope, fluorine-18, powers medical imaging techniques such as positron emission ...
Phys.org / Silver-coated cicada wing nanostructures boost molecular detection signals
Zoom in far enough on an empress cicada wing, and a strange landscape materializes. At the nanoscale, densely packed spires rise from the surface, covering the wing in an endless grove of bowling pins.
Phys.org / Uncovering early embryonic communications using new stem cell model
From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly.
