Scientists have been able to instantly cure rats of cocaine addiction, by applying laser l...

Like so many other illicit drugs, cocaine can be extremely, destructively addictive. Recent research suggests, however, that ridding people of such addictions may be as simple as zapping them on them scalp. In a study conducted at the National Institutes of Health (NIH), and at the Ernest Gallo Clinic and Research Center at UC San Francisco, scientists were able to turn cocaine addiction on and off in rats via pulses of laser light to their brains.  Read More

The Bitcoin - global anarchist financial revolution, giant scam, great investment or some ...

This could turn out to be one of the most remarkable stories of our era – or one of the biggest scams in human history. Bitcoin, the anonymous digital currency, is more than four years old now, and a single bitcoin has gone from being worth literally nothing in 2009 to being worth nearly US$30 at current market values. Here's a quick primer on the Bitcoin system, how some anonymous programmers managed to create 300 million dollars out of thin air, what you can do with bitcoins, and a few words of warning.  Read More

Seattle’s Presage Biosciences has developed a device which introduces small amounts of different chemotherapy drugs into a patient's tumor. The tumor is inspected after removal and the most effective of the drugs are used for post-surgical chemotherapy, resulting in more efficient, personalized cancer treatments. The new device is awaiting FDA approval, but is currently being used to facilitate development of new chemotherapy drugs.  Read More

DrinkSavvy cups, glasses and straws are designed to alert their users if date rape drugs h...

Odorless, colorless, and tasteless, so-called “date rape” drugs are nasty, sneaky things. When surreptitiously added to someone’s drink, they cause that person to become disoriented, sleepy, slow-to-react, and otherwise easier to sexually assault. Making things worse, the victim usually can’t remember what happened while they were drugged, making prosecution or even identification of the assailant difficult. Now, however, a new invention known as DrinkSavvy may allow people to know if such drugs have been put in their drink.  Read More

Methamphetamine addicts may one day be able to receive a vaccine, that keeps them from get...

Methamphetamine is one of the most addictive and thus commonly-used street drugs – according to the United Nations Office on Drugs and Crime, there are currently nearly 25 million meth addicts worldwide. Help may be on the way, however. Scientists from The Scripps Research Institute have had success in using a methamphetamine vaccine to block the effects on meth on lab rats.  Read More

The acoustic levitator was originally developed for NASA to simulate microgravity conditio...

In a new development which on first glance resembles a storyline plucked from the pages of Harry Potter, researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, Illinois, have adopted a system of levitation in order to more effectively develop pharmaceuticals - no magic wand required.  Read More

Nobody likes getting their shots, but whether childhood immunization, annual flu vaccination, or whatever else, we're required to undergo the uncomfortable sensation of needle piercing skin multiple times throughout our lives. However, a new laser-based system promises to take the “ouch” out of injections by delivering shots as painlessly as being struck by a puff of air.  Read More

Researchers have found a way to block addiction to various opioid drugs, including heroin ...

Unlike the heroin-specific vaccine we covered last year, an international team of scientists from the University of Adelaide in Australia and the University of Colorado Boulder has now found a way to block addiction to various opioid drugs, including heroin and morphine. Importantly, the new approach doesn’t negatively affect the pain-relieving properties of these drugs.  Read More

The U.S. Food and Drug Administration has approved the prophylactic use of the antiviral d...

While there are many methods for preventing HIV transmission that work in principle (abstinence, safe sex, monogamy to some extent), in practice efforts to prevent new HIV infections have reached a plateau - about 50 thousand new cases are reported every year in the United States and no progress has been made on reducing this number for at least 15 years, with the overall rate of infection remaining stable since at least 2004. In response to the almost complete lack of effective prevention methods, the U.S. FDA (Food and Drug Administration) has now approved the prophylactic use of the anti-retroviral combination drug Truvada, to reduce the risk of people acquiring HIV.  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
