Why an Allosaurus's butt is worse than its bite
At up to 12 metres long and weighing as much as two tonnes, the Allosaurus is recognised as having been one of the fiercest dinosaurs of the late Jurassic age. But its slender teeth and sometimes narrow jaw bone have left scientists puzzled as to how the Allosaurus managed to hunt prey... view more (2001-02-19)

Choosing healthy embryos in IVF
A revolutionary method for detecting which human embryos are most likely to develop successfully to the stage at which they implant in the womb has been developed by scientists at the University of York and clinicians at Leeds General Infirmary. The research has been funded by the Medical Research... view more (2002-05-07)

Learning visual prosthesis at the Hanover Fair
When the idea appeared several years ago, it sounded persuasive: How about implanting electrodes at the defective retina of blind subjects and connecting them with a mini camera in order to re-establish vision.   view more (2007-04-13)

Researchers seek to make cavity-causing bacteria self-destruct
Bacteria that eat sugar and release cavity-causing acid onto teeth may soon be made dramatically more vulnerable to their own acid. Researchers have identified key genes and proteins that, if interfered with, can take away the ability of a key bacterial species to thrive as its acidic waste builds... view more (2008-01-03)

Biophysical method may help to recover hearing
Scientists based in Switzerland and South Africa have created a biophysical methodology that may help to overcome hearing deficits, and potentially remedy even substantial hearing loss. The authors propose a method of retuning functioning regions of the ear to recognize frequencies originally... view more (2008-08-29)

Free radical scavenging is defective in periodontal (tooth loosening) disease
The capacity to mop up harmful oxygen free radicals seems to be reduced in people with periodontal disease, finds research in Molecular Pathology. Periodontal disease affects between 10 and 15% of people worldwide. A leading cause of tooth loss, it develops as a result of bacterial infection from a... view more (2002-11-22)

Engineers develop way of detecting problems with artificial hip joints

Adult brain cells rediscover their inner child
You may not be able to relive your youth, but part of your brain can. Johns Hopkins researchers have found that newly made nerves in an adult brain's learning center experience a one-month period when they are just as active as the nerves in a developing child.   view more (2007-05-24)

Therapeutic Cloning No Longer A Dream, Says Scientist Who Produced First Cloned Embryonic Stem Cell
A member of the team who were the first in the world to produce stem cells from a cloned human embryo told the 20th annual conference of the European Society for Human Reproduction and Embryology on Wednesday 30 June that the work could generate potentially unlimited undifferentiated stem cells.... view more (2004-06-30)

Bioactive cement scaffold may improve bone grafts
A new technology for implants that may improve construction or repair of bones in the face, skull and jaw, has been developed by researchers from the American Dental Association Foundation (ADAF) and the National Institute of Standards and Technology (NIST).   view more (2006-04-18)

Computer program useful tool in dental care
Gunnel H'¤nsel Petersson at Malmö University in Sweden has received an award for her studies of Cariogram, a computer program created in Malmö to assess patients' risk of developing tooth decay, dental caries. The program was constructed in 1997 by Professor Douglas Bratthall at the... view more (2005-02-25)

Hope for arthritis stems from within
Leeds bioengineers have developed an innovative technique for cartilage repair combining the self-healing powers of the body with stem cell science to help young people avoid debilitating knee problems and give hope to arthritis sufferers.   view more (2006-01-31)
