A team of international scientists say the prospects for finding a cure for AIDS in the near future are realistic, after unveiling a roadmap to cure the disease in Washington overnight. Major investments in science have resulted in the worldwide availability of over 20 anti-HIV drugs. Despite these successes, these therapies have limitations. They do not eradicate HIV, requiring people to remain on expensive and potentially toxic drugs for life. The new roadmap to cure is intent on ending this suffering.
In what organisers are calling a first, scientists have come up with a coordinated plan to tackle AIDS since the disease was discovered 31 years ago. Over the past two years the International AIDS Society – IAS – has convened a group of international experts to develop a roadmap for research towards an HIV cure. Published online in an abridged form tomorrow, Friday July 20, in Nature Reviews Immunology, Towards an HIV Cure identifies seven important priority areas for basic, translational and clinical research and maps out a path for future research collaboration and funding opportunities.(

New research by the Australian National University has found children who are solely breastfed in the first six months of life are at greater risk of developing a nut allergy.
There has been a sharp rise in nut allergies in Australian children over the past 20 years, but until now the medical world has found it hard to explain the risk factors.
ANU researchers found it is not the breast milk itself that seems to be the culprit, but rather the traces of nuts contained in it. The link between the two was investigated using the ACT Kindergarten Health Check Questionnaire in a study conducted by the ANU Medical School and the ACT Health Directorate.
Of the 15,000 preschool children studied, 3.2 per cent had a peanut allergy while 3.9 per cent were allergic to other nuts :: Read the full article »»»»

Researchers in the US have mapped the genome of an unborn fetus, the breakthrough marks a significant advance in prenatal and genetic medicine, but also one that raises profound ethical issues. As a result, researchers at the University of Washington say they will be able to screen a foetus that is only eight weeks old for thousands of genetic disorders with an accuracy of 98 per cent.
Currently, the common procedure for pregnant women who want to check their baby for genetic, chromosomal abnormalities is Amniotic Fluid Test – AFT – or Amniocentesis, it’s a risky procedure in which a small amount of amniotic fluid, which contains foetal tissue is sampled – via a very large needle – from the amnionic sac surrounding the fetus.
Researchers were able to map the genomes of two fetus’ via non-invasive maternal blood and paternal saliva samples taken from two pregnant women halfway into their second trimester at 18 weeks gestation. The samples contained enough information to accurately interpret the babies DNA :: Read the full article »»»»

Back in July 2011 we published an exciting little post on MIT’s work with artificial leaves – MITs Artificial Leaf – based on a silicon solar cell.
The leaf consists of a thin, flat, three-layered silicon solar cell with catalysts bonded to both faces of the silicon. Placed in water and exposed to sunlight, silicon absorbs photons of sunlight, generating electrons with enough energy to conduct through the silicon.
The process leaves behind positively charged electron vacancies called “holes” that can also move through the material. The holes migrate to a cobalt-containing catalyst painted on one face of the silicon cell, where they strip electrons from water molecules, breaking them into hydrogen ions (H+), and oxygen atoms. The catalyst then knits pairs of oxygens together to make O2. Meanwhile, the H+ ions migrate to another catalyst on the opposite face of the silicon cell, where they combine with conducting electrons to make molecules of H2. In principle, the H2 can then be stored and either burned or run through a fuel cell to generate electricity.
Professor Daniel Nocera’s work has finally borne fruit. Nocera’s team developed the catalyst three years ago, the first practical artificial leaf has now been developed, and this new technology may help to deliver efficient carbon neutral energy to the world’s poor and developing nations.
Building on their previous research, the researchers at MIT in Boston have created an artificial leaf that, unlike earlier devices is made from inexpensive materials, and employs low-cost engineering and manufacturing processes :: Read the full article »»»»
