A chemical that affects the biological clock could help provide a new class of drugs to tr...

Scientists have long suspected that metabolic disorders, such as type 2 diabetes and obesity, could be linked to our circadian rhythm or biological clock. For example, laboratory mice with altered biological clocks often become obese and develop diabetes. Now biologists at UC San Diego have discovered that a chemical, which affects the activity of a key protein that regulates our biological clock, can repress the production of glucose by the liver, offering a promising new direction for the development of a new class of drugs to treat diabetes.  Read More

One of the more promising developments in the field of medical technology involves the use of microspheres for targeted drug delivery. In a nutshell, this encompasses creating tiny hollow balls that are filled with a specific drug, which travel directly to a specific organ or area of diseased tissue. Once there, the spheres release their medication, keeping it concentrated where it’s needed while sparing other tissue from any harmful side effects. Recently, a team of scientists from Germany’s Max Planck Institute of Colloids and Interfaces devised a new method of manufacturing such microspheres, which is said to offer several advantages over existing techniques.  Read More

A new cancer treatment targeting cellular 'protein factories' is set to begin clinical tri...

Researchers at Melbourne’s Peter MacCallum (Peter Mac) Cancer Centre are set to begin clinical trials of a cancer treatment they say represents a major shift in molecular approaches to treating the disease. The treatment, which has proven successful in the lab against lymphoma and leukemia cells, targets the production of proteins within the heart of cancer cells, while leaving healthy cells relatively unaffected.  Read More

The synthetic protein EP67 acts on the immune system to attack the influenza virus (Colori...

We’ve seen promising moves towards developing a universal or near-universal influenza vaccine, but researchers at the Donald P. Shiley BioScience Center have taken a different tack to ward of the crafty virus. Although the flu virus actively keeps the immune system from detecting it for a few days, giving it time to gain a foothold, the researchers have found that a powerful synthetic protein, known as EP67, can kick start the immune system so that it reacts almost immediately to all strains of the virus.  Read More

Magnetic resonance. We all think of the massive multimillion dollar magnetic resonance imaging machines into whose gaping mouth we are slowly propelled on a motorized table, ready to have our smallest flaws exposed. But the phenomenon of magnetic resonance has other medical uses. A team of physicians and scientists led by Prof. Ralph Weissleder of Massachusetts General Hospital (MGH) has developed a handheld diagnostic magnetic resonance (DMR) device that can diagnose cancer in an hour with greatly improved accuracy compared to the current gold standard. The DMR technique is sensitive enough that only material from a fine needle aspiration biopsy is needed for the test - a far less painful experience compared to the usual surgical or core needle biopsies.  Read More

The Chronius project has developed a T-shirt fitted with sensors to remotely monitor patie...

No one likes going to the doctor. There's the inevitable wait in the waiting room before eventually being ushered into the office of the harried doctor who spends most of his day dealing with relatively minor complaints or simple follow-up visits. Then, of course, there's the bill. But what if patients could get a check up without having to actually visit the doctor? A smart T-shirt fitted with various sensors is designed to do just that.  Read More

Scientists have created genetically-modified mosquitoes that are incapable of spreading ma...

Last year, Prof. Anthony James announced that he and his colleagues had genetically altered Aedes aegypti mosquitoes in a fashion that could drastically reduce their populations. In a nutshell, the altered genes cause the female mosquitoes to be born without wings – this makes it rather difficult for them to go foraging for blood, and turns them into easy prey for almost any predator. The non-biting males are born with wings, and subsequently go off and mate with unmodified females, passing the modified genes along to their offspring. Now, James has done some more genetic engineering, to create mosquitoes that can’t spread malaria.  Read More

The new ultra-sensitive biosensor has been demonstrated by detecting very small concentrat...

A new ultra-sensitive test developed by scientists from the Imperial College London and Spain’s University of Vigo has the potential to detect the earliest stages of a disease, thereby giving any treatment the best possible chance of succeeding. The researchers claim their new biosensor test is capable of detecting biomarkers (molecules which indicate the presence of a disease) at concentration levels much lower than is possible with existing biosensors. While the new test has already proven capable of detecting a biomarker associated with prostate cancer, the team says their biosensor could be easily reconfigured to detect biomarkers related to other diseases or viruses.  Read More

One of the biggest problems in fighting the spread of AIDS has always been convincing people to have themselves tested regularly. Unfortunately, getting someone to take a trip to a clinic isn't always easy, particularly in areas where there aren't many options for discreet testing. In a development that could leap right over this privacy hurdle, the U.S. Food and Drug Administration has just unanimously approved an over-the-counter HIV test that enables people to test themselves in their own home and receive results in just 20 minutes.  Read More

The thumb-sized Domino chip can perform 20 genetic tests from a drop of blood

A genetic testing mini-lab developed by researchers at the University of Alberta to set to begin commercial trials within a year. The Domino system provides a portable, cheap and powerful alternative to conventional laboratories that delivers a range of point-of-care diagnostic possibilities including tests for blood borne diseases such as malaria and those affecting farm animals.  Read More
