Phys.org / Immunosuppressive nanoparticles slow atherosclerosis progression in animal models
Scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC), in collaboration with national and international research centers, have identified a key immune cell subtype involved in the development ...
Phys.org / New model helps to figure out which distant planets may host life
The search for life beyond Earth is a key driver of modern astronomy and planetary science. The U.S. is building multiple major telescopes and planetary probes to advance this search. However, the signs of life—called biosignatures—that ...
Phys.org / Subantarctic Mode Waters traced to distinct origins in Indian and Pacific oceans
In the southern flanks of the Indian Ocean and the central and eastern Pacific, just north of the Antarctic Circumpolar Current, lie the Subantarctic Mode Waters. As part of the global ocean conveyor belt, these large masses ...
Phys.org / Working model reveals how protein anillin controls asymmetry during embryonic cell division
Symmetry is a fundamental characteristic of most multi-cell animals. However, the cell division of embryonic cells is asymmetric. A team led by Prof. Dr. Esther Zanin at the Department of Biology at Friedrich-Alexander-Universität ...
Phys.org / Iron from coal and steel industries alters North Pacific ecosystem, study reveals
Along with nutrients like nitrogen and phosphorus, iron is essential for the growth of microscopic phytoplankton in the ocean. However, a new study led by oceanographers at the University of Hawaii'i (UH) at Mānoa revealed ...
Phys.org / Hijacking the cell: How poxvirus modifies ribosome function to spread
Northwestern Medicine scientists have uncovered new details about how poxvirus hijacks its host's protein synthesis machinery to multiply and spread, according to a study published in Nature Microbiology.
Phys.org / Redefining physics to roll a ball vertically
Researchers from the University of Waterloo have achieved a feat previously thought to be impossible—getting a sphere to roll down a totally vertical surface without applying any external force.
Phys.org / Shelved Europa Lander mission concept could be used to explore Enceladus instead
A team of engineers at NASA's Jet Propulsion Laboratory has outlined the decade-long development and testing of what was originally known as the Europa Lander prototype—a partially autonomous robot designed to find out ...
Phys.org / 5,000-year-old Egyptian blue pigment recreated using ancient methods
A team of Washington State University-led researchers has recreated the world's oldest synthetic pigment, called Egyptian blue, which was used in ancient Egypt about 5,000 years ago.
Phys.org / Your ketchup will see you now: Solid-phase properties reveal when yield stress fluids start to flow
Pounding on the bottom of a glass bottle of ketchup is one of life's small annoyances. Getting that sweet, red concoction from its solid phase to a liquid takes too long when you're hungry and could even require messy strategies ...
Phys.org / Cave records show that US's deepest river gorge Hells Canyon is only 2.1 million years old
North America's deepest gorge, Hells Canyon, which slithers along the border of Idaho and Oregon, is a surprisingly new addition to the Earth's ancient landscape. A recent study suggests that a monumental shift in Snake river ...
Phys.org / Asteroseismology study uncovers new pulsation modes in ultra-massive white dwarf
Based on time-series photometry from three different telescopes, an international team of astronomers has performed a detailed asteroseismology study of WD J0049−2525—the most massive pulsating white dwarf. The study, ...
