Phys.org / Earth formed from material exclusively from the inner solar system, planetary scientists show
Planetary scientists have long debated where the material that formed Earth comes from. Despite its location in the inner solar system, they consider it likely that 6–40% of this material must have come from the outer solar ...
Phys.org / Scientists solve 40-year-old biological mystery behind sleeping sickness
To survive in the human bloodstream, the African trypanosome parasite wears a "cloak" made of proteins known as a variant surface glycoprotein (VSG). The study, published in Nature Microbiology, identifies the protein that ...
Phys.org / Sacrifice before the cataclysm: The aromas of Pompeii's household altars
The destruction of Pompeii preserved ash residues on the household altars of its inhabitants. An international research team has scientifically investigated for the first time what was burned in Roman incense burners from ...
Phys.org / Quantum twisting microscope reveals electron-electron interactions in graphene at room temperature
An international team of researchers built a highly sensitive quantum microscope and used it to directly observe, for the first time at room temperature, how electrons subtly interact with each other in graphene—confirming ...
Phys.org / Nanoparticles can genetically modify several human cell types
In a demonstration that could help pave the way for gene therapies with fewer side effects, several human cell types have been genetically modified with protein nanoparticles designed at University of Michigan Engineering ...
Phys.org / Cornerstone model of evolutionary biology built on math flaw, study argues
New research is significantly revising a widely cited evolutionary model, the Inhibitory Cascade Mode (ICM). Benjamin Auerbach, professor in the Department of Ecology and Evolutionary Biology at the University of Tennessee, ...
Phys.org / Next-generation optical sensor can read photon spin across UV-to-infrared wavelengths
A research team led by Professor Jiwoong Yang of the Department of Energy Science and Engineering at DGIST has developed next-generation optical sensor technology capable of precisely detecting not only the intensity and ...
Phys.org / Cyclic catalysts use sunlight and air to regenerate during pharma ingredient synthesis
In chemical processes for producing pharmaceuticals, catalysts are a core technology that determines production speed and cost. However, until now, there has been a trade-off between "precise but disposable catalysts" and ...
Phys.org / Tasmanian tiger lives on in Arnhem Land rock art
The striped dog-like marsupial we know as the Tasmanian tiger has long been surrounded by mystery, and the subject of scientific curiosity. Now, newly discovered rock art depicting Tasmanian tigers and Tasmanian devils in ...
Phys.org / Quantum researchers engineer extremely precise phonon lasers
When lasers were invented in the 1960s, they opened new avenues for scientific discovery and everyday applications, from scanners at the grocery store to corrective eye surgery. Conventional lasers control photons—individual ...
Phys.org / Stabilized laser components could shrink quantum computers from room- to chip-scale
Scientists in the Riccio College of Engineering at the University of Massachusetts Amherst and the University of California Santa Barbara have demonstrated key laser and ion trap components necessary to help drastically shrink ...
Phys.org / 100 million years ago, an 'evolutionary fuse' was lit in the deep ocean, sparking squid diversification
From color-changing skin to jet-propelled motion, squid and cuttlefish have long fascinated scientists. To understand the origins of their unique characteristics, many attempts have been made to define their evolutionary ...
