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

Blocking a marijuana-like chemical in the brain could allow one to eat more, exercise less...

Unless you're a rodent, it's probably too early to get excited about the possibility of being able to eat all you want, be a couch potato and still not gain weight, but new research using a strain of specially-modified mice indicates that just such an unlikely scenario might one day be possible. Recently, a team of scientists from UC Irvine (UCI), Yale and Marche Polytechnic University in Ancona, Italy discovered they could bring this metabolic miracle about in the lab by blocking the actions of a marijuana-like compound that regulates energy metabolism.  Read More

War, plague, famine, heart disease, cigarettes, road trauma: six very effective killers of human beings. But they're all amateurs when their records are compared to the number one mass murderer of all time. The humble mosquito, and the deadly diseases it carries, is estimated to have been responsible for as many as 46 billion deaths over the history of our species. That staggering number is even more frightening in context - it means that mosquitoes are alleged to have killed more than half the humans that ever lived. So if any species deserves the full wrath of human technology, this is the one. And here, it seems, is how we might take our revenge - genetically modified strains of mosquito that are designed to cripple their own offspring and systematically destroy entire populations. And these mutant, auto-genocidal mozzies are already loose in the wild.  Read More

The new micro-lattice material is so light that it can sit atop dandelion fluff without da...

Researchers have created a new metallic material that they claim is the world’s lightest solid material. With a density of just 0.9 mg/cm3 the material is around 100 times lighter than Styrofoam and lighter than the "multiwalled carbon nanotube (MCNT) aerogel" - also dubbed "frozen smoke" – with a density of 4 mg/cm3 that we looked at earlier this year. Despite being 99.99 percent open volume, the new material boasts impressive strength and energy absorption, making it potentially useful for a range of applications.  Read More

A scientist has created a version of the classic OutRun driving video game, that can actua...

Some people who spent their youth in the 80s miss that era, and wish that things now were like they were then. Well, those people might be interested in the University of California at Irvine’s OutRun Project. With the ultimate aim of developing gaming therapy systems for people such as quadriplegics, scientists involved in the project have created a kind of combination electric golf cart and arcade-style video game console. Players can actually drive the cart down the road, while an augmented reality feature displays the real-life road on the screen in front of them, but in the form of Sega’s classic 8-bit road racing game, OutRun.  Read More

A new study from the University of California indicates that LED lights contain toxic meta...

LED light bulbs are becoming increasingly popular with designers and consumers of green technology, as they use less electricity, last longer, and emit more light on a pound-for-pound basis than traditional incandescent bulbs. However, while it may be tempting to look at them as having solved the problem of environmentally-unfriendly lighting, researchers from the University of California would advise against such thinking.  Read More

We’ve heard of surgeons using a SpectroPen during the tumor removal surgeries, but now Californian scientists are shedding light on cancer, literally, in the hopes to find a new cure for skin cancer. The team of scientists from the University of California, Irvine are currently developing new techniques to image cancerous lesions using LEDs (light emitting diodes) with the hope of then being able to treat skin cancer using photodynamic therapy (PDT).  Read More

Deep dissection of brain-stem with the corticospinal tract visible in red

According to the Christopher & Dana Reeve Foundation, about two percent of Americans – more than six million people – have some form of paralysis resulting from spinal cord injury, which is due primarily to the interruption of connections between the brain and spinal cord. Such paralysis and loss of function has long been considered untreatable, but a new approach has, for the first time, induced robust regeneration of nerve connections that control voluntary movement, showing the potential for new therapeutic approaches to paralysis and other motor function impairments and offering hope to sufferers.  Read More
