Phys.org / This tiny organism simply loves corners, using geometry to sense its world
A surprising observation in the lab has revealed a remarkable ability in Stentor coeruleus, a single-celled organism about one millimeter long. Sometimes nicknamed the "platypus" of microorganisms for its trumpet-like shape, ...
Phys.org / Cell lineage tracing reveals early‑segregated germline in plants
August Weismann's germ plasm theory of the late 19th century posited that only germ cells, e.g., sperm and egg cells in animals or pollen and ovule cells in plants, transmit genetic information to the next generation, and ...
Phys.org / 'Serendipitous' discovery of Martian ripple marks reveals an ancient sandstorm
The search for life on Mars involves the efforts of scientists from many different disciplines. An important aspect of that search is to study Martian sedimentary rocks for information about the planet's environment when ...
Phys.org / Deep mantle deformation is linked to subducted slabs, global map shows
Slow roiling convection currents deep within Earth's mantle, which are associated with the movements of tectonic plates, also deform the material of the mantle itself. Now, a new study in The Seismic Record confirms that ...
Phys.org / Compact flat-lens system can generate nondiffracting bottle beams
Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long distances. To overcome this challenge, ...
Dialog / New 2D material demonstrates capability for ultrathin waveplates
Polarization has always been a core property of light that is essential for a broad range of everyday applications, including displays (LED, LCD, 3D Cinematics), photography, as well as satellite and antenna technologies. ...
Phys.org / Backyard birdwatchers help scientists uncover what hawks really like to eat
Anyone who keeps a bird feeder has likely had the same uneasy thought after seeing a sudden blur of wings in the yard: What was that hawk doing here?
Phys.org / Novel approach to quantum error correction portends a scalable future for quantum computing
A University of Sydney quantum physicist has developed a new approach to quantum error correction that could significantly reduce the number of physical qubits required to build large-scale, fault-tolerant quantum computers. ...
Phys.org / Engineered E. coli dependency may help contain microbes to defined areas
Take a typical fish out of the water and it won't live long. It gets the oxygen it needs from the water it swims in. In a similar way, scientists are exploring dependency as a method of controlling what microbes can do and ...
Phys.org / A global carbon credit program risks rewarding the wrong behavior
A United Nations-backed framework for protecting tropical forests could allow governments to collect income from carbon credits without advancing forest conservation. The weakness lies in how the program calculates baselines, ...
Phys.org / Rudeness may be rewarded—as a response to rudeness
If you don't have anything nice to say, perhaps it's OK to say it anyway—if responding to someone who has treated you or your team rudely, new Cornell research suggests. Civil responses to disrespectful behavior remain the ...
Phys.org / UV light method offers repeat recycling for acrylic plastics without the environmental cost
A breakthrough method for chemically recycling acrylic—one of the world's most widely used plastics—has been developed by researchers at the University of Bath. In contrast to conventional mechanical recycling, this method ...
