Autism Heredity
Autism is a disorder of neural development characterized by impaired social interaction and verbal and non-verbal communication, and by restricted, repetitive or stereotyped behavior. The diagnostic criteria require that symptoms become apparent before a child is three years old. Autism affects information processing in the brain by altering how nerve cells and their synapses connect…

Weather Extremes UN Report
It is hard to tell how bad or good the weather really is. One has to look back over a period of time to perceive true changes. The world experienced unprecedented high-impact climate extremes between 2001 and 2010 and more national temperature records were broken during that period than in any other decade, according to…

What Color was that Dinosaur?
The past is in black and white. It is very hard to tell what color was a dinosaur from looking at its fossilized bones. In the past, experts have basically guessed what color ancient animals were as colors are rarely preserved in fossils. But recent discoveries of color-producing structures in fossil insects and feathers are…

Cloudy Worlds Climate
Clouds are pretty to see. They are also much more potent than previously perceived in modifying climate. This is particularly important when considering habitable planets near red dwarf stars. A new study that calculates the influence of cloud behavior on climate doubles the number of potentially habitable planets orbiting red dwarfs, the most common type…

Fruit Fly Propagation
Fruit flies, to humans, are an annoying batch of little critters. But to other fruit flies, there is a different picture. A team led by University California researchers has discovered a sensory system in the foreleg of the fruit fly that tells male flies whether a potential mate is from a different species. The work…

Dinosaur Growth
Tracking the growth of dinosaurs and how they changed as they grew is difficult since all the evidence there is consists of fossils. Using a combination of biomechanical analysis and bone histology, palaeontologists from Beijing, Bristol, and Bonn have shown how one of the best-known dinosaurs switched from four feet to two as it grew.…

Knobby Pareiasaurs
During the Permian era, the Earth was dominated by a single supercontinent called Pangea – “All-Earth”. Animal and plant life dispersed broadly across this land, as documented by identical fossil species found on multiple modern continents. But a new study published in the Journal of Vertebrate Paleontology supports the idea that there was an isolated…

Plant Math
Humans do math or at least some humans can do so. New research shows that to prevent starvation at night, plants perform accurate arithmetic division. The calculation allows them to use up their starch reserves at a constant rate so that they run out almost precisely at dawn. Plants feed themselves during the day by…

A Catalyst to Convert CO2 to Fuel
Carbon dioxide is the result of burning fuel to make things like cars work. Plants slowly convert that CO2 back to something organic to begin the process again. Working in his lab in the University of Delaware’s Department of Chemistry and Biochemistry, Joel Rosenthal and doctoral student John DiMeglio have developed an inexpensive catalyst that…

The Jet Stream and Greenland
There are many dynamics in the world. There are many global phenomena. Add the the jet stream to climate change. Research from the University of Sheffield has shown that unusual changes in atmospheric jet stream circulation caused the exceptional surface melt of the Greenland Ice Sheet (GrIS) in the summer 2012. An international team led…
