Antipsychotic drugs are approved mainly for treating schizophrenia and bipolar disorder, but they are also used for many other purposes. One of the most controversial is reducing disruptive behavior among elderly people with dementia.

In the last few years, the FDA has required drug labels to carry warnings regarding this still-common practice, and studies continue to raise questions about its risks and benefits.

Concern about this issue is not new.

Highlighting the extreme weather conditions hitting Europe, space sensors aboard ESA’s Envisat satellite have detected the worst floodwaters to hit Britain for 60 years and deadly fires raging through southern Europe.

Heavy rains caused the River Thames to burst its banks on Wednesday, forcing the evacuation of hundreds of homes in Britain’s university city of Oxford. The flooding across England and Wales has left tens of thousands without electricity and water.

The Environment Agency still has three severe flood warnings in place – two on the Thames around Oxford and one on the Ock River near Oxfordshire. In areas where flooding is beginning to recede, sanitation officials are warning of health risks posed by stagnant waters.

An artificial big toe attached to the foot of an ancient Egyptian mummy could prove to be the world's earliest functional prosthetic body part, say scientists. If true, the toe will predate what is currently considered to be the earliest known practical prosthesis - Roman Capua Leg from 300BC, made from bronze - by several hundred years. The leg was held at the Royal College of Surgeons in London but was destroyed by Luftwaffe bombs during the Second World War.

Research at The University of Manchester is hoping to prove that the wood and leather artefact in the Cairo Museum not only looked the part but also helped its owner walk 'like an Egyptian'.

One of the greatest medical mysteries of our time has taken a leap forward in medical understanding with new study results announced by Dr. Daniel D. Rubens of Children’s Hospital and Regional Medical Center in Seattle.

Rubens’ study found all babies in a Rhode Island study group who died of Sudden Infant Death Syndrome (SIDS) universally shared the same distinctive difference in their newborn hearing test results for the right inner ear, when compared to infants who did not have SIDS.

This is the first time doctors might be able to identify newborns at risk for SIDS by a simple, affordable and routine hearing test administered shortly after birth.

An international team of scientists, including several at The Johns Hopkins University, has detected a hidden magnetic “quantum order” that extends over chains of nearly 100 atoms in a material that is otherwise magnetically disordered.

The findings, which are published online today (July 26) in the journal Science, may have implications for the design of devices and materials for quantum information processing, including large-scale quantum computers capable of tackling problems exponentially faster than can conventional computers.

The team’s results are important because they demonstrate that the magnetic moments (the measure of the strength of a magnetic source) of a large number of atoms can band together to form quantum states much like those of a very large molecule.

Scientists from two European-funded groups - EuroStemCell (European Consortium for Stem Cell Research) and ESTOOLS - are working together to call for a relaxation of current laws, particularly in Germany and Italy, in the hope that their European counterparts are able to collaborate on international projects without fear of legal reprisal.

Currently, stem cell legislation differs across Europe. Projects that are perfectly legal in Sweden and the UK could result in a three-year prison sentence in Germany. Researchers from countries with very restrictive legislation might also become liable by taking on coordinating positions in other European institutions.
