Researchers have developed a method for measuring the strength of certain ion–electron interactions in water, with initial tests throwing up unexpected results.
Researchers have demonstrated quantum gate operations in a system where voltage pulses cause neighboring electron spins to swap with one another.
If a helical bacteria’s tail propulsion is strong enough to deform the yield-stress fluid ahead of the swimmer, locomotion proceeds.
A trio of evolutionary biologists, two with Carleton University, the other with Seoul National University, has apparently solved the paradox of aposematism—how animals managed to evolve with bright colors to warn predators of their toxic nature. In their paper study, published in the journal Science, Karl Loeffler-Henry, Changku Kang and Thomas Sherratt, conducted an analysis of the family tree of over 1,000 frog, salamander and newt species.
For many years, evolutionary biologists have puzzled over the seeming paradox of aposematism, in which animals such as frogs develop bright colors to warn potential predators that eating them will make them sick or even kill them. How could such colors have evolved? Animals that stand out tend to be the first caught and eaten, preventing the evolution of even brighter colors from occurring. In this new effort, the research team set out to solve this riddle.
The work involved analyzing the family tree of 1,100 species of frogs, salamanders and newts, looking for evidence of evolution of aposematism in a new way—by breaking them down into more categories than previous efforts—five instead of two: conspicuous, cryptic, partially conspicuous, fully conspicuous and polymorphic.
Two newly discovered genes have been linked to schizophrenia while a previously known gene associated with schizophrenia risk has also been linked to autism in a massive new study.
Scientists say the findings increase our understanding of brain diseases and could lead to new treatment targets.

Scientists have been testing various materials for the construction of such habitats on Mars. An innovation in this field comes from scientists at the University of Manchester. They have developed a new ‘cosmic concrete’ composed of extraterrestrial dust, a press release stated.

For decades we have dreamed of true holographic displays for entertainment, communication, and education. Star Wars had 3D projections rendered in real-time — the definition wasn’t great, but they were communicating across interplanetary distances — and Avatar had holographic maps showcasing the terrain of Pandora. In reality, we mostly have 2D images which show dimension and depth when viewed from different angles. That might be on the verge of changing.
Pierre-Alexandre Blanche from the Wyant College of Optical Sciences at the University of Arizona recently published a paper in Light: Advanced Manufacturing which acts as a roadmap toward true 3D holographic displays.

Segregation of chromosomes in dividing cells can be disrupted if the cells are constrained by their surroundings.
One of the aberrant features of cancer cells is a failure to distribute chromosomes properly when the cells divide. Researchers have now found that a specific problem with the chromosome-distribution machinery can become more common in cancer cells confined within shallow microscopic channels—but also that, surprisingly, increasing the physical constraints can suppress these errors [1]. Such confinement mimics the effects of crowding by surrounding cells in a tumor, and the researchers believe the results might help to explain what goes awry in cancers and perhaps offer clues to how it might be put right.
In a healthy, dividing cell, after the genome is replicated, the chromosomes are segregated into two groups. Both groups are bound to the mitotic spindle, a bundle of aligned filaments (called microtubules) that are pinched together at the ends into structures called poles. The chromosomes are then drawn along the microtubules toward the poles. A key cause of improper chromosome segregation in cancer cells is the formation of spindles with more than two poles. Multipolar spindle formation inside living organisms may differ from the phenomenon when observed in cells grown in a dish [2], so it is possible that the confining effect of the surrounding cells in a tissue has some influence on this process.
