Medical Xpress / New imaging tools help cancer researchers see inside living cells
A new study co-led by an Oregon Health & Science University researcher describes a breakthrough in microscopy tools that could dramatically expand how cancer biology labs study the inner workings of living cells. The research, ...
Phys.org / Preconception radiation exposure alters offspring mitochondrial DNA in an organ-specific manner
It did not take long after the discovery of X-rays in the 1890s for scientists to begin exploring the harmful effects of radiation on living organisms. Yet even after more than a century of research, new insights continue ...
Phys.org / Revived Nubian royal robes shed light on prestige and authority in a lost Christian kingdom
A recent archaeological project has physically reconstructed the ceremonial dress of medieval Nubian royalty and clergy, offering a rare glimpse into how clothing shaped and communicated authority in Christian Nubia. The ...
Medical Xpress / One-third with inflammatory bowel disease have moderate-to-severe disability, review finds
Moderate-to-severe disability affects nearly one-third of patients with inflammatory bowel disease (IBD), according to a review published online in Inflammatory Bowel Diseases.
Tech Xplore / Phase-changing VO₂ turns methane into propane and hydrogen more efficiently
Converting methane, the primary component of natural gas, into higher alkanes and hydrogen, could be highly advantageous. Alkanes, such as propane and butane, are easier to transport than methane and are used in a wider range ...
Phys.org / Extinct ice age giants in Bender's Cave challenge existing climate records for the Edwards Plateau
A recent study by Dr. John Moretti of the University of Texas and local caver John Young uncovered the remains of Ice Age megafauna, revealing an entirely new ecosystem that once thrived on the Edwards Plateau. Among the ...
Phys.org / A backyard bug repellent is derailing bumblebees' ability to navigate
In the summer, many people turn to mosquito repellents to reduce the insects' buzzing and bites. One solution that has become increasingly popular in recent years is the Thermacell device, which releases vaporized, pyrethroid-based ...
Phys.org / Dark volcanic ash has visibly reshaped Martian surface since 1976
Noticeable change on Mars often takes millions of years—but the European Space Agency's Mars Express has captured a blanket of dark ash creeping across the planet in just decades.
Phys.org / Wild Canadian freshwater fish reveal opioid and antidepressant buildup downstream
Fish living downstream of wastewater treatment plants are accumulating antidepressants, opioids and other drugs of abuse in their bodies, according to a new study. Using a new analytical method they developed, a team of researchers ...
Phys.org / Powerful imaging pulls lost ocean life from 445-million-year-old stone and exposes a hidden extinction record
New technology has helped a team of scientists uncover more than 20 microscopic fossils, including a species previously unknown to science. The discovery may provide us with fresh insights into the Late Ordovician, one of ...
Phys.org / Cut off from making fat, parasitic wasps lose pheromones, fail to form eggs and cannot reproduce
The Easter holidays are over and many people have once again experienced firsthand how easily sweets can be converted into fat. Parasitic wasps are also capable of converting sugar into fat—a capability that long was thought ...
Phys.org / Researchers synthesize photosynthetic molecule found in bacteria
Researchers from North Carolina State University have successfully synthesized bacteriochlorophyll a, which is a photosynthetic pigment found in bacteria that absorbs infrared light. The work represents the first chemical ...
