Alzheimer’s Disease Neuroimaging Study Launched Nationwide by the National Institutes of Health

The Alzheimer’s Disease Neuroimaging Initiative (ADNI) — a project developed by the National Institutes of Health (NIH) — is seeking 800 older adults to participate in a study aimed at identifying biological markers of memory decline and Alzheimer’s disease (AD). Ultimately, scientists hope that brain and biological changes can be detected before memory decline and other symptoms appear, allowing the effectiveness of drugs to be evaluated at the earliest possible time.

Constructal theory predicts global climate patterns in simple way

A unifying physics principle that describes design in nature predicts, in surprisingly straightforward fashion, the basic features of global circulation and climate, according to researchers at Duke University’s Pratt School of Engineering and the University of Evora in Portugal. They said the new approach to climate may have important implications for forecasting environmental change.

The researchers found that the “constructal theory” can predict the global circulation that

First simultaneous cochlear implant operation for WA

A 25-year-old man will undergo Western Australia’s first ever simultaneous bilateral cochlear implant operation on Thursday 9 February at St John of God Hospital in Subiaco.

Danny Clarke will have two cochlear hearing devices implanted in both his ears at the same time.

Danny, who became a successful search and rescue helicopter air crewman despite losing his hearing in his right ear due to a fall at the age of 11, became permanently deaf last year after being at

Molecular breakthrough will add grist to the mill for wheat breeders

A team of scientists at the John Innes Centre(1) in Norwich, UK led by Dr Graham Moore have a completely new understanding of the structure of a gene complex in wheat that controls the pairing of its chromosomes, knowledge of which has the potential to revolutionise wheat breeding.

Dr Moore said “The transfer of useful traits such as disease, drought and salt tolerance from wild species into wheat is a difficult and complex process. This new insight into the molecular nature of Ph1 and how

Data security: A problem in search of a mathematical theory

The need for security in electronic communications is crucial in today’s world. The foundation for providing this security rests on mathematics. In particular, a certain kind of mathematical function called a “hash function” is central in the design of cryptographic systems that protect electronic communications. But recently the most secure hash function in use today was shown to be vulnerable to attack. An article in the upcoming issue of the Notices of the AMS describes these attacks and

Obesity may be factor in accelerated type I diabetes in some patients

Obesity, long known as a cause of type II diabetes, may accelerate the onset of type 1 diabetes in some – but not all – groups of younger patients, according to research at Wake Forest University School of Medicine and six clinical sites nationally.

“The increasing prevalence of childhood obesity may substantially account for the younger age at onset of type 1 diabetes observed in various populations,” said the research team, writing in the February issue of Diabetes Care.
