New Fast, Portable Device can Perform Highly Accurate and Sensitive Tests

Posted:

Testing for cocaine or any other drugs usually involves two steps: a quick on-site prescreen, and then a more accurate and elaborate confirmatory test at a distant laboratory. This process can take days or weeks - but that's too long in many cases where public safety is at risk. Now, researchers report development of a backpack-sized device that can perform highly accurate and sensitive tests anywhere within 15 minutes. The study appears in ACS' journal iAnalytical ...

Researchers Treat Incarceration as a Racial Epidemic Disease

Posted:

Researchers claim that the incarceration rate has nearly quadrupled since the U.S. declared a war on drugs. Along with that, racial disparities abound. Incarceration rates for black Americans are more than six times higher than those for white Americans, according to the U.S. Bureau of Justice Statistics. To explain these growing racial disparities, researchers at Virginia Tech are using the same modeling techniques used for infectious disease outbreaks ...

Researchers Discover 165 Million Year Old Parasite

Posted:

From the University of Bonn and China, researchers have come across around 165 million years old fossil fly larva with an amazing sucking tool. The parasite, an elongate fly larva around two centimeters long, had undergone extreme changes over the course of evolution: The head is tiny in comparison to the body, tube-shaped with piercer-like mouthparts at the front. The mid-body (thorax) has been completely transformed underneath into a gigantic sucking plate; the ...

Vietnamese Women Trafficked to China as Brides

Animal Testing Methods for Endocrine Disrupting Chemicals Should Change

Posted:

Challenging risk assessment methods used for decades by toxicologists, a new review of the literature suggests that oral gavage, the most widely accepted method of dosing lab animals to test chemical toxicity, does not accurately mimic how humans are exposed to chemicals in everyday life. The review was led by environmental health scientist Laura Vandenberg at the University of Massachusetts Amherst. Oral gavage refers to the way researchers give chemicals to animals ...

Monarch Butterflies Employ a Magnetic Compass During Migration

The study carried out by Australian scientists found that eliminating gluten from diet brought about a reduction in problems related to attention, memory and ...

CNIO Researcher Revises the Role of Cohesin in Cancer

Posted:

Massive sequencing of cancer genomes every day brings to light new genes that could be involved in the process of tumour formation. A good example of this is cohesin, a ring-shaped protein complex that embraces DNA to control cell division. Just a few months ago, and after several studies in the same direction, the sequencing of thousands of tumour samples identified the STAG2 gene-whose product forms part of cohesin-as one of the most frequently mutated genes ...

Genes that increase the risk of developing schizophrenia may also increase the likelihood of using cannabis. This is according to a new study led by King's College London, published today in iMolecular Psychiatry/i. Previous studies have identified a link between cannabis use and schizophrenia, but it has remained unclear whether this association is due to cannabis directly increasing the risk of the disorder. The new results suggest that part ...
