Phys.org / Shark strongholds: Remote Pacific islands host thriving populations as coastal marine reserves falter
One of the most comprehensive surveys to date of shark and other large predator fish in the Eastern Tropical Pacific (ETP) ocean finds that remote marine protected areas (MPAs)—including the Galapagos, Malpelo, Clipperton, ...
Phys.org / Telescope in Chile captures stunning new picture of a cosmic butterfly
A telescope in Chile has captured a stunning new picture of a grand and graceful cosmic butterfly.
Phys.org / Non-toxic solvent enables near-perfect recycling of mixed-fiber textiles
We are producing more textiles than ever before: worldwide, well over one hundred million tons of textiles are manufactured every year—more than twice as much as in the year 2000. This makes it increasingly important not ...
Phys.org / First-of-its-kind 3D model lets you explore Easter Island statues up close
Located in the middle of the South Pacific, thousands of miles from the nearest continent, Easter Island (Rapa Nui) is one of the most remote inhabited places on Earth. To visit it and marvel at the quarries where its iconic ...
Phys.org / OLEDs can now switch light's handedness with an electrical signal
Researchers from the University of Oxford have for the first time discovered an approach to electrically switch organic LEDs (OLEDs) to emit either left- or right-handed circularly polarized light without changing the light-emitting ...
Phys.org / Electric discharges detected on Mars for the first time
On Mars, winds constantly stir up whirlwinds of fine dust. It was at the center of two of these dust devils that the SuperCam instrument's microphone, the first ever to operate on Mars, accidentally recorded particularly ...
Phys.org / Mini-fridges on a nanoscale? New cooling technique could make computer chips more powerful
As more devices get piled onto computer chips to increase processing power capacity, heat generation becomes increasingly concentrated. This heat must be removed to keep chip performance high, but is currently achieved by ...
Phys.org / Novel mRNA therapy curbs antibiotic-resistant infections in preclinical lung models
Researchers at the Icahn School of Medicine at Mount Sinai and collaborators have reported early success with a novel mRNA-based therapy designed to combat antibiotic-resistant bacteria.
Phys.org / The collapse of Maya civilization: Drought doesn't explain everything
Between 750 and 900 CE, the population of the Maya lowlands in Central America experienced a major demographic and political decline which, according to the scientific literature, coincided with repeated episodes of intense ...
Phys.org / Uncovering a new genetic code in archaea opens doors for bioengineering applications
The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in which one or two additional ...
Phys.org / Ancient hominin fossils reveal two human ancestors lived side by side
With the help of newly identified bones, an enigmatic 3.4-million-year-old hominin foot found in 2009, is assigned to a species different from that of the famous fossil Lucy providing further proof that two ancient species ...
Phys.org / Brain's GPS hasn't changed in millions of years: Specialized neurons may be vital to evolutionary survival
The same brain cells linked to disorientation in Alzheimer's disease have been preserved—and even slightly increased—across millions of years of evolution.
