Dissolving the problem: Organic vapor induces dissolution of molecular salts It has long been known that when salt is kept in a humid environment, it absorbs water, dissolving some of the salt and making it clump. Now, researchers from Japan have discovered that water vapor isn't the only agent that can do this.
Researchers describe new kangaroo fossil from Papua New Guinea Australian paleontologists from Flinders University have described a new genus of giant fossil kangaroo from the mountains of central Papua New Guinea.
Understanding how microbiota thrive in their human hosts A research team lead by scientists from the Max Planck Institute for Biology, Tübingen, Germany, has now made substantial progress in understanding how gut bacteria succeed in their human hosts on a molecular level. They investigated how bacteria produce inositol lipids, substances vital for many cellular processes in humans and other eukaryotes but hitherto rarely observed in bacteria. The results, now published in the journal Nature Microbiology, indicate that inositol lipids have implications for the symbiosis between the bacteria and their hosts.
Physicists confront the neutron lifetime puzzle To solve a long-standing puzzle about how long a neutron can "live" outside an atomic nucleus, physicists entertained a wild but testable theory positing the existence of a right-handed version of our left-handed universe. They designed a mind-bending experiment at the Department of Energy's Oak Ridge National Laboratory to try to detect a particle that has been speculated but not spotted. If found, the theorized "mirror neutron"—a dark-matter twin to the neutron—could explain a discrepancy between answers from two types of neutron lifetime experiments and provide the first observation of dark matter.
Tiny nanoturbine is an autonomous machine smaller than most bacteria A turbine only a few dozen nanometres in size made from DNA rotates in salty water without having to be pushed which makes it a tiny autonomous machine. It could be for speeding up chemical reactions or transporting particles inside cells
Shine a light: New research shows how low-energy light can bend plastic A team of Florida State University researchers has uncovered a way to use low-energy light to manipulate photopolymers or plastic films—a finding that has implications for a wide range of technologies that use light as an energy source to create shape-shifting structures.
Identifying bird species by sound, an app opens new avenues for citizen science The BirdNET app, a free machine-learning powered tool that can identify over 3,000 birds by sound alone, generates reliable scientific data and makes it easier for people to contribute citizen-science data on birds by simply recording sounds.
Nearly 1 in 4 globally at risk from severe flooding: study Almost a quarter of the world's population are exposed to significant flood risks, according to new research published Tuesday, which warned those in poorer countries were more vulnerable.
Mirror Image Pinpoints a Nanoparticle’s Position
Author(s): Rachel Berkowitz
A scattered laser beam’s interaction with itself creates a motion-detection method precise enough to determine whether a trapped particle is in its ground state.

X-Ray Fireworks Linked to Fast Radio Bursts
Author(s): Sophia Chen
Predictions indicate that when a neutron star radiates a burst of radio waves, interactions of the burst with the star’s magnetic field should produce observable x rays.
