Quarks In The Mirror
2014-02-06 12:22:26

DOE/Thomas Jefferson National Accelerator Facility From matching wings on butterflies to the repeating six-point pattern of snowflakes, symmetries echo through nature, even down to the smallest building blocks of matter. Since the discovery of quarks, the building blocks of protons and neutrons, physicists have been exploiting those symmetries to study quarks' intrinsic properties and to uncover what those properties can reveal about the physical laws that govern them. A recent...

Scientists Look At Genetic Cause Of Left-Right Handedness
2013-09-13 16:44:53

Brett Smith for redOrbit.com – Your Universe Online For the ten percent of us who are left-handed, don’t feel bad about being an outsider because like Lady Gaga – you were born that way. According to a new study in the peer-reviewed journal PLOS Genetics, handedness is determined at the embryonic stage in the womb. Study researchers said they were able to identify a network of genes that have a hand in establishing left-right asymmetry. “The genes are involved in the...

SLAC National Accelerator Laboratory Time's quantum arrow has a preferred direction, new analysis shows Time marches relentlessly forward for you and me; watch a movie in reverse, and you´ll quickly see something is amiss. But from the point of view of a single, isolated particle, the passage of time looks the same in either direction. For instance, a movie of two particles scattering off of each other would look just as sensible in reverse — a concept known as time reversal...

Asymmetric Warfare Between Earwigs Probed By Researchers
2012-08-16 07:07:24

Symmetrical looks are highly prized in the animal kingdom, but according to a new report by San Francisco State University biologists on an insect called the maritime earwig, asymmetry might come with its own perks. Animals–including humans–seem to use symmetry as a shortcut for evaluating potential mates. Symmetrical features usually indicate normal development, while asymmetry could point to an underlying developmental defect that would render a mate less fit. "The...

Mechanism For Organ Placement Shared By Human Cells, Plants, Worms And Frogs

New research identifies special protein that determines what goes where As organisms develop, their internal organs arrange in a consistent asymmetrical pattern--heart and stomach to the left, liver and appendix to the right. But how does this happen? Biologists at Tufts University have produced the first evidence that a class of proteins that make up a cell's skeleton -- tubulin proteins -- drives asymmetrical patterning across a broad spectrum of species, including plants, nematode...

Foreign Language Skills Aid Business Choices
2012-04-26 06:40:19

Connie K. Ho for RedOrbit.com "A foreign language provides a distancing mechanism that moves people from the immediate intuitive system to a more deliberate mode of thinking." These are the words of a University of Chicago (U Chicago) professor and his team of researchers in a new study on economics and language. They bring fresh perspective into language and the role it plays in business decision-making. The study, titled "The Foreign Language Effect: Thinking in a Foreign Tongue...

A research team at the Hubrecht Institute, Utrecht, demonstrates a mechanism by which left—right asymmetry in the body is established and maintained. The study, published in the open-access journal PLoS Genetics on September 29, offers a new model of how families of genes interact to promote and direct body asymmetry. Although organisms appear bilaterally symmetrical when observed from the outside, internal organs are positioned asymmetrically along the left—right axis, and the...

A University of Warwick physicist has produced a galaxy sized solution which explains one of the outstanding puzzles of particle physics, while leaving the door open to the related conundrum of why different amounts of matter and antimatter seem to have survived the birth of our Universe. Physicists would like a neat universe where the laws of physics are so universal that every particle and its antiparticle behave in the same way. However in recent years experimental observations of...

UBC and TRIUMF physicists have proposed a unified explanation for dark matter and the so-called baryon asymmetry--the apparent imbalance of matter with positive baryon charge and antimatter with negative baryon charge in the Universe. The visible Universe appears to be made of atoms, and each of these atoms carries a positive baryon charge equal to total number of protons and neutrons in its nucleus. However, since the discovery of antimatter in 1932, researchers have wondered why the...

Scientists at the Wellcome Trust Centre for Human Genetics, University of Oxford, have identified a genetic variant which influences whether a person with dyslexia is more skilled with either the left or right hand. The finding identifies a novel gene for handedness and provides the first genetic evidence to support a much speculated link between handedness and a language-related disorder. The majority of people worldwide are right-handed. Since the left side of the brain controls the right...


Word of the Day

  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
