Planning for a summer delivery for your child? You might want to choose an ophthalmologist along with an obstetrician.

If your child is born in the winter or fall, it will have better long-range eyesight throughout its lifetime and less chance of requiring thick corrective glasses, predicts a Tel Aviv University investigation led by Dr. Yossi Mandel, a senior ophthalmologist in the Israel Defense Forces Medical Corps.

Forming a large multi-center Israeli team, the scientists took data on Israeli youth aged 16-23 and retroactively correlated the incidence of myopia (short-sightedness) with their month of birth. The results were astonishing.

Researchers at BRIC, University of Copenhagen, have identified a new gene family (UTX-JMJD3) essential for embryonic development. The family controls the expression of genes crucial for stem cell maintenance and differentiation, and the results may contribute significantly to the understanding of the development of cancer.

All organisms consist of a number of different cell types each producing different proteins. The nerve cells produce proteins necessary for the nerve cell function; the muscle cells proteins necessary for the muscle function and so on. All these specialized cells originate from the same cell type – the embryonic stem cells.

Neuroscientists at University College London and Ghent University have found the brain circuit involved in thinking twice and checking impulsive behaviour. The duo discovered that an area in the fronto-median cortex of the brain is activated when you begin to think ‘I’m not going to go through with this’ and stop yourself doing what you were about to do.

According to the study, published in the ‘Journal of Neuroscience’ today, this specific brain network is involved in self-control and checks and limits our desired actions.

A Swedish researcher says astrococytes, the most abundant cell type in the brain, can lead to new treatment for stroke victims.

Stroke is the result of an infarction, or bleeding, within the brain, and it may lead to impaired movement, impaired sensation, and difficulties in cognitive function and speech. Approximately 30,000 people are affected by stroke each year in Sweden, and it is the most common cause of long-term dependence on care.

"Researchers all over the world are intensively searching for new treatments. One interesting possibility is that of activating stem cells in the damaged brain such that the brain can be repaired and regain its function", says stem cell researcher Jonas Faijerson.

300 years after its discovery, the crystal structure of mercury fulminate has been determined.

Though well known by alchemists for its explosive capability and later used as a detonator for dynamite, mercury fulminate's crystal structure has been unknown until now. As Wolfgang Beck, Thomas Klapötke and their team report in the journal ZAAC – Journal of Inorganic and General Chemistry, the orthorhombic crystals consist of separate, nearly linear Hg(CNO)2 molecules.

The alchemists of the seventeenth century were already aware that mixtures of “spiritus vini” (ethanol) and mercury in “aqua fortis” (nitric acid) made for an explosive brew.

A situation in which wages increase 2.3% and prices increase 3.1% is equivalent to a situation in which wages fall by 0.8% at constant prices. Though the two scenarios are equivalent in real terms there are people who perceive these situations differently. These people are said to be prone to 'money illusion.'

It has been commonly thought that the impact of irrational behavior is limited in markets because “smart agents” can take advantage of irrational traders.

Female rhesus monkeys use special vocalizations while interacting with infants, the way human adults use motherese, or “baby talk,” to engage babies’ attention, new research at the University of Chicago shows.

“Motherese is a high pitched and musical form of speech, which may be biological in origin,” said Dario Maestripieri, Associate Professor in Comparative Human Development at the University.

Huntington's is an inherited degenerative neurological disease that affects up to 8 people out of every 100,000 in Western countries. Any person whose parent has Huntington's has a 50-50 chance of inheriting the faulty gene that causes it and everyone with the defective gene will, at some point, develop the disease.

It is characterized by a loss of neurons in certain regions of the brain and progressively affects a sufferer’s cognition, personality and motor skills. In its later stages, sufferers almost certainly require continual nursing care.
