State Court Rules on Medicinal Marijuana Law, Orders Implementation

It appears that Arizona Governor Janet Brewer's attempt to block the imposition of Proposition 203 has come to an end. Last week, a Maricopa County judge dismissed the lawsuit that sought to block the portion of the law that allowed state-run marijuana dispensaries. According to a report by the Arizona Republic, Superior Court judge Richard Gama ruled that the state did not have any discretion in whether the voter-supported initiative could proceed. The law, named the Arizona Medicinal Marijuana Act (AMMA) legalizes marijuana use for people with chronic or debilitating ...

Pneumonia wonder drug: Zinc saves lives

Respiratory tract infections, including pneumonia, are the most common cause of death in children under the age of five. In a study looking at children given standard antibiotic therapy, new research published in BioMed Central's open access journal BMC Medicine shows how zinc supplements drastically improved children's chances of surviving the infection. The increase in survival due to zinc (on top of antibiotics) was even greater for HIV infected children. In a double-blind, randomized, placebo-controlled trial, 350 children, aged from six months to five years old, ...

Counties with thriving small businesses have healthier residents, LSU and Baylor researchers find

Counties and parishes with a greater concentration of small, locally-owned businesses have healthier populations — with lower rates of mortality, obesity and diabetes — than do those that rely on large companies with "absentee" owners, according to a national study by sociologists at LSU and Baylor University. "What stands out about this research is that we often think of the economic benefits and job growth that small business generates, but we don't think of the social benefits to small communities," said Troy C. Blanchard, Ph.D., lead author and associate professor ...

Researchers increase understanding of gene's potentially protective role in Parkinson's

TUSCALOOSA, Ala. — Treatments for Parkinson's disease, estimated to affect 1 million Americans, have yet to prove effective in slowing the progression of the debilitating disease. However, University of Alabama researchers have identified how a specific gene protects dopamine-producing neurons from dying in both animal models and in cultures of human neurons, according to a scientific article publishing in the Feb. 8 edition of The Journal of Neuroscience. This increased understanding of the gene's neuro-protective capability is, the researchers said, another step toward ...

The Future of Internet Policy Bills

On January 24, 2012, Congress was scheduled to vote on whether to debate two controversial bills regarding Internet privacy and intellectual property. The Protect Intellectual Property Act (PIPA) and the Stop Online Piracy Act (SOPA) were meant to limit online piracy and stem copyright infringement. However, they were met with fervent opposition from civil liberties advocates, privacy groups, online search engines and millions of consumers. Congressional offices were swamped with phone calls, letters and emails calling for legislators not to support the bill. In fact, ...

Why the middle finger has such a slow connection

The fingers on the outside – i.e. the thumb and little finger - therefore react faster than the middle finger, which is exposed to the "cross fire" of two neighbours on each side. Through targeted learning, this speed handicap can be compensated. The working group led by PD Dr. Hubert Dinse (Neural Plasticity Lab at the Institute for Neuroral Computation) report in the current issue of PNAS. Thumb and little finger are the quickest The researchers set subjects a simple task to measure the speed of decision: they showed them an image on a monitor that represented all ...

An electronic green thumb

A green thumb is required where plants are to grow abundantly – that also applies to watering them in dry areas. If they are watered too much, then the soil becomes saline; if the plants receive too little moisture, they let their leaves droop and, in the worst case, they wither. In the future, sensors in the soil, a central unit and an associated app will supplement the green thumb: one look at the smart phone and the farmer will know what moisture content the soil has. Which plants need water, which do not? If the plants get too dry, the farmer is alerted by SMS; the ...

Entire genome of extinct human decoded from fossil

In 2010, Dr. Svante Pääbo and his colleagues presented a draft version of the genome from a small fragment of a human finger bone discovered in Denisova Cave in southern Siberia. The DNA sequences showed that this individual came from a previously unknown group of extinct humans that have become known as Denisovans. Together with their sister group the Neandertals, Denisovans are the closest extinct relatives of currently living humans. The Leipzig team has now developed sensitive novel techniques which have allowed them to sequence every position in the Denisovan genome ...

New Federal Regulations for Truckers in 2012: Do They Go Far Enough?

At the end of 2011, the Federal Motor Carrier Safety Administration (FMCSA) set forth a new set of rules pertaining to truckers' work schedules. The updated FMCSA hours-of-service regulations for commercial vehicle operators were officially published on December 27. Some advocates are now applauding the United States Department of Transportation (USDOT) for tightening certain requirements, but are questioning whether hours-of-service regulations could be doing more to protect motorists. In the end, the FMCSA declined to reduce the daily driving time maximum from the ...

MIT: New tool for analyzing solar-cell materials

To make a silicon solar cell, you start with a slice of highly purified silicon crystal, and then process it through several stages involving gradual heating and cooling. But figuring out the tradeoffs involved in selecting the purity level of the starting silicon wafer — and then exactly how much to heat it, how fast, for how long, and so on through each of several steps — has largely been a matter of trial and error, guided by intuition and experience. Now, MIT researchers think they have found a better way. An online tool called "Impurities to Efficiency" (known ...

North Carolina Workers' Compensation: Who Is an "Employee"?

Workers' compensation has become part of the fabric of the employer-employee relationship in North Carolina and across the U.S. In essence, an employer purchases insurance to cover the cost of work-related employee injuries and illnesses. This mandated coverage replaces the uncertainty of an employee having to sue his or her employer for work-related medical expenses and lost wages. In almost all situations, when a work injury happens, both parties know medical costs and lost wages will be handled through the workers' compensation system, regardless of who was at fault. The ...
