Phys.org / Self-blinking 'fairy lights' allow DNA to be imaged at almost double-helix-width resolution
Researchers have developed fluorescent molecules that permit imaging of how DNA is packaged inside living cells at unprecedented resolution and, in preserved cells, at a resolution close to the width of the double helix itself.
Phys.org / Motorboat noise stunts growth and impairs predator escape in reef fish, study shows
Coral reef fish that are exposed to motorboat noise grow up smaller and less able to dodge predators, new research shows. Scientists played either boat noise or natural reef sounds to a species from the Great Barrier Reef ...
Phys.org / Tracks and tooth marks reveal bone-crushing dogs at Nebraska supervolcano ashfall site
Thirty-five years on—well, 12 million, technically—Ashfall Fossil Beds State Historical Park continues to offer important glimpses of prehistoric life in Nebraska.
Phys.org / A Google-like search engine for single-cell RNA data could answer previously impossible questions
Imagine doctors could understand exactly which cells caused a patient's cancer or whether pathogens contributed to the disease. They could then use the information to tailor a treatment plan to the patient's specific cancer. ...
Phys.org / Breathable smart sensor developed for real-time hazardous gas detection on masks
A research team led by Sungwon Lee, a professor in the Department of Physics and Chemistry at DGIST, developed a hierarchical nano-on-nano structure by directly growing graphene nanowalls (GNWs) on polymer nanofibers and ...
Phys.org / How methylation sets a parasite in motion to invade host cells
Parasites such as Toxoplasma gondii and the malaria parasite Plasmodium falciparum depend on rapid, precisely controlled movement to complete their life cycles. To start moving, they must assemble actin filaments at their ...
Phys.org / Low oxygen could limit insects' uphill escape from climate warming
Reduced oxygen levels and air pressure at higher elevations may limit insects' ability to move upslope to escape a warming climate, with potential consequences for the essential services they provide, like pollination, according ...
Phys.org / Compound with the potential to treat drug-resistant HIV identified
A large international team has developed a new compound that showed strong antiviral activity against HIV, including some drug-resistant variants.
Phys.org / Milky Way's own gravity can mimic dark matter clues, stellar stream simulations suggest
Most of the stars in our Milky Way galaxy sit neatly on a flat plane. But the space around our galaxy is much more chaotic. Rogue bands of stars called "stellar streams" orbit the Milky Way much like planets in our solar ...
Phys.org / Major polluters are worsening the Western US water crisis: A new way to measure who's responsible
Climate change was once something scientists warned us about, and now it's a reality we are living in. In California's Central Valley, about one-third of climate-related groundwater loss between 2003 and 2024 can be attributed ...
Phys.org / Deep underground, SuperCDMS begins hunting light dark matter with 24 cryogenic crystals
In the hunt for one of nature's most elusive substances—dark matter, which makes up 85% of all matter in the universe—scientists are going to extremes. Deep underground and chilled to near absolute zero, the Super Cryogenic ...
Phys.org / Ancient DNA reveals cacao was consumed in present-day Georgia 1,000 years ago
One of the world's favorite sweet treats, chocolate, may have been enjoyed in eastern North America much earlier than previously thought, about 1,000 years ago. New research published in the journal PLOS One suggests that ...
