Why being preterm could impair memory, learning New research at the University of Adelaide has demonstrated that teenagers born prematurely may suffer brain development problems that directly affect their memory and learning abilities. The research, conducted by Dr Julia Pitcher and Dr Michael Ridding from the University of Adelaide's Robinson Institute, shows reduced 'plasticity' in the brains of teenagers who were born preterm (at or before 37 weeks gestation). The results of the...

Genetics researchers at the University of Adelaide have solved a 40-year mystery for a family beset by a rare intellectual disability — and they've discovered something new about the causes of intellectual disability in the process. While many intellectual disabilities are caused directly by a genetic mutation in the so-called "protein coding" part of our genes, the researchers found that in their case the answer laid outside the gene and in the regulation of proteins. Protein...

Predator And Prey: Tiny Wasp Hunts Venomous Redback Spider
2012-09-12 05:48:04

Lee Rannals for redOrbit.com - Your Universe Online Even Australia's most common dangerous spider is no match for a nearly forgotten 200 year old flying insect, according to recent findings. The wasp, Agenioideus nigricornis, was first discovered in 1775 by Danish etymologist Johan Christian Fabricius. Recently, researchers from the University of Adelaide said the small wasp is a predator of the redback spider. "Since then, scientists have largely forgotten about the wasp," said...

Heroin And Morphine Addiction Can Now Be Blocked
2012-08-16 07:17:36

Clinical trials possible within 18 months In a major breakthrough, an international team of scientists has proven that addiction to morphine and heroin can be blocked, while at the same time increasing pain relief. The team from the University of Adelaide and University of Colorado has discovered the key mechanism in the body's immune system that amplifies addiction to opioid drugs. Laboratory studies have shown that the drug (+)-naloxone (pronounced: PLUS nal-OX-own) will...

A large international study led by University of Adelaide researchers has found that women who use marijuana can more than double the risk of giving birth to a baby prematurely. Preterm or premature birth - at least three weeks before a baby's due date - can result in serious and life-threatening health problems for the baby, and an increased risk of health problems in later life, such as heart disease and diabetes. A study of more than 3000 pregnant women in Adelaide, Australia and...

University of Adelaide researchers have discovered that recent climate change is causing leaves of some Australian plants to narrow in size. The study, which is the first of its kind in the world, highlights that plant species are already responding to changes in climate. The results are published online today in the Royal Society journal Biology Letters. Researchers analysed leaves from herbarium specimens of Narrow-leaf Hopbush (Dodonaea viscosa subsp. angustissima) dating from the...

Researchers from the University of Adelaide are hoping to better understand why the mutated genes for breast and ovarian cancer are not passed on more frequently from one generation of women to the next. That's despite a documented link between breast cancer genes and increased fertility in women. Dr Jack da Silva from the University's School of Molecular & Biomedical Science says that because women who carry breast cancer genes are more fertile, in theory they have a greater chance...

A University of Adelaide study has identified the risk of major birth defects associated with different types of assisted reproductive technology. In the most comprehensive study of its kind in the world, researchers from the University's Robinson Institute have compared the risk of major birth defects for each of the reproductive therapies commonly available internationally, such as: IVF (in vitro fertilization), ICSI (intracytoplasmic sperm injection) and ovulation induction. They also...

Fertility injections used to help overcome male reproductive issues could increase the risks of birth defects in the children they sire, a new study published in the New England Journal of Medicine (NEJM) has discovered. The study, which was led by researchers at the University of Adelaide's Robson Institute, examined a total of 308,000 South Australian births over an 18-year period, and discovered that children born as a result of intracytoplasmic sperm injection (ICSI) were more likely...

Pollen Can Protect Mahogany From Extinction
2012-04-04 03:28:58

New research from the University of Adelaide could help protect one of the world's most globally threatened tree species - the big leaf mahogany - from extinction. Big leaf mahogany (Swietenia macrophylla) is the most prized mahogany timber around the world. It is at risk of extinction in its native habitats because of the timber trade, particularly in Central and South America. To better understand how such a threatened species can be brought back from the brink of extinction,...
