Free Neutron’s Lifetime

To answer the big questions, sometimes we must look to the very small. Researchers at the Los Alamos Neutron Science Center’s Ultracold Neutron Source, within Los Alamos National Lab, have been passing the cryo-baton for more than a decade, working at ever colder temperatures in order to study the behavior …

Toroidal Droplets & Liquid Lattices

When two substances are brought together, they will eventually settle into a steady state called the thermodynamic equilibrium. In new research, a team of physicists at Aalto University wanted to disrupt this state to see what happens; they subjected combinations of oils with different dielectric constants and conductivities to an …

Personality Traits in Cats

A team of scientists at the University of Helsinki has studied cat personality and behavior by collecting a large dataset of 4,316 cats from 56 different breeds, house cats and mixed breed cats, with online questionnaires. Mikkola et al. examined the structure, test-retest reliability, inter-rater reliability, convergent validity and discriminant …

Trehalulose Rich Honey

Organic chemists at the University of Queensland have found that an unusual bioactive disaccharide called trehalulose, which is a feature of stingless bee honey, while not dominant in any other foods, is produced in the gut of stingless bees.

Avian Brain Shape

A team of paleontologists has digitally reconstructed the facial skeleton and brain endocast of Ichthyornis dispar, a toothed stem bird that lived in North America during the Late Cretaceous epoch and has traditionally been considered the nearest known well-understood relative of living birds. The ancestors of living birds had a …

World’s Smallest Acoustic Amplifier

An acoustic amplifier developed by Sandia National Laboratories researchers measures 0.5 mm2 (0.0008 square inches), and is more than 10 times more effective than the earlier versions. The acousto-electric chip includes a radio-frequency amplifier, circulator and filter; SEM image shows details of the amplifier. Image credit: Bret Latter / Matt …

Genetic Super Tomatoes

Humans have been grafting plants onto other plants for thousands of years, but only in the last few generations have we understood the genetic implications of the technique. Researchers from Penn State and the University of Florida partnered with a Nebraska startup to combine genetically “stressed” roots with regular tomato …

Organic Matter And Water

An international team of scientists has studied both the water and organic contents from a dust particle recovered from the surface of the near-Earth S-type asteroid 25143 Itokawa by JAXA’s Hayabusa mission, which was the first mission that brought pristine asteroidal materials to Earth. The S-type asteroid Itokawa. Image credit: …

Space Hurricane Ionosphere

Hurricanes in the Earth’s low atmosphere are well known; however, disturbances resembling hurricanes had never before been detected in the upper atmosphere.
