Phys.org / DNA's physical properties may shape which mutations evolution preserves
Nearly every cell in the human body contains essentially the same genetic information, yet different cells activate different genes. For regulatory proteins to reach these genes, DNA must be accessible. This accessibility ...
Medical Xpress / Living near dry cleaners linked to increased likelihood of Parkinson's disease
People living near dry cleaners may have a higher risk of developing Parkinson's disease, according to a new nationwide study led by researchers at Barrow Neurological Institute in Phoenix.
Medical Xpress / Intermittent fasting may help type 1 diabetics control their blood sugar levels
A UIC study led by kinesiology and nutrition professor Krista Varady found that time-restricted eating may be a safe, effective tool to control blood sugar in adults with type 1 diabetes. The work is published in the journal ...
Tech Xplore / At 0.8 nanometers, carbon film may replace two layers in future chip wiring
As transistors inside microchips continue to shrink, the metal wiring that connects them is becoming a growing obstacle to faster, more energy-efficient chips. Narrower wires have greater electrical resistance, while smaller ...
Phys.org / Illuminating the limits of the international unit of light, the candela
The candela, the international unit of light in use for almost a century, forms the basis of photometry. According to a new study, measurements derived from it systematically misjudge the brightness of colored light sources ...
Phys.org / Researchers build 'digital twin' to model Manhattan air quality
Cornell engineers have developed a "digital twin" framework that creates a real-time virtual representation of urban carbon dioxide conditions, providing a tool that could help city planners monitor emissions, identify hotspots ...
Phys.org / Decode the chatter of birds with a neuroscientist
If you're not a bird person, you may not be able to distinguish between the different sounds birds make. Birdsong—the courting and territorial vocalization of songbirds—has been studied for decades, but less is understood ...
Medical Xpress / Simple mouth rinse may help detect stomach and colorectal cancer signals
It's widely understood that the microbiome—especially microbes found in the mouth and the gut—can have a profound effect on health. In a study published in the journal Cell Host & Microbe on Aug. 20, researchers report that ...
Medical Xpress / New guide could help scientists see deeper into the human body using light and sound
Scientists have published the most comprehensive analysis to date of ultrasound detectors underpinning photoacoustic tomography (PAT)—a fast-emerging medical imaging technology capable of revealing blood vessels, tumors and ...
Medical Xpress / New rapid test could transform iron treatment worldwide
Iron deficiency is one of the world's most common nutritional disorders, affecting millions of women and children globally. Yet diagnosing it remains difficult in many low-resource settings, where access to laboratories and ...
Phys.org / How sex sheds evolutionary baggage
Why is there sex—or, more precisely, sexual reproduction? If you're an evolutionary biologist, the answer isn't obvious. Sexual reproduction is biologically costly, requiring not only competition for mates but also the creation ...
Phys.org / Tobacco companies helped flood the federal comment process that stalled menthol cigarette ban
When the U.S. Food and Drug Administration (FDA) proposed banning menthol cigarettes and flavored cigars in 2022, nearly 250,000 public comments flooded in—a record response that led the Biden administration to delay a final ...
