25 million people are living with schizophrenia in low and middle income countries and over two-thirds of them are not receiving any treatment.

Dr Vikram Patel discusses the crucial role that community health workers can play. Dr Saaed Farooq argues that the huge burden of untreated schizophrenia could be tackled by providing free antipsychotic medications and supervising patients while they take their treatment (akin to the way in which patients with TB are supervised when they take their antituberculous medications). Dr R Thara discusses the crucial importance of tackling the stigma of schizophrenia by offering proven therapies.

In the first large-scale epidemiological study evaluating elevator-related injuries in children throughout the United States, researchers report that children up to two years of age had the greatest percentage (28.6%) of elevator-related injuries.

“What really surprised us was the number of infants with head injuries in our study. As the elevator doors closed mothers may not realize the vulnerability of babies in strollers or in their arms,” said Joseph O’Neil, M.D., M.P.H., assistant professor of clinical pediatrics at the Indiana University School of Medicine and lead author of the study.

A University College London researcher says stereotypes can be a good thing for autistic kids. Autistic children are unable to understand individuals and why they do things but are better with understanding groups. Stereotyping was able to help them learn, for example, if a woman were used as an example of someone who likes to bake/

Professor Uta Frith of the UCL Institute of Cognitive Neuroscience said: “One of the main problems experienced by autistic children is that they are unable to understand why others are doing certain things: what motivates them or what they are thinking and feeling. Most of us have this ability, known as ‘Theory of Mind’.

The discovery of small perforated sea shells, in the Cave of Pigeons in Taforalt, eastern Morocco, has shown that the use of bead adornments in North Africa is older than thought. Dating from 82 000 years ago, the beads are thought to be the oldest in the world.

As adornments, together with art, burial and the use of pigments, are considered to be among the most conclusive signs of the acquisition of symbolic thought and of modern cognitive abilities, this study is leading researchers to question their ideas about the origins of modern humans.

An all-electric aircraft will be more efficient, produce fewer greenhouse emissions and be quieter but current technology cannot be used because an electric motor using conventional magnets can weigh up to five times as much as conventional jet engine and not be as fuel efficient.

Superconducting motors are the answer to greenhouse emissions from plane flights, according Philippe Masson and Cesar Luongo from Florida State University, Gerald Brown at NASA and Danielle Soban at Georgia Institute of Technology. They explain that because superconductors lose no energy through electrical resistance, they could be very efficient components for a new type of aircraft propulsion.

Genes account for only 2.5 percent of DNA in the human genetic blueprint, yet diseases can result not only from mutant genes but from mutations of other DNA that controls genes.
