The same hotspot in Earth's mantle that feeds Iceland's active volcanoes has been playing a trick on the scientists who are trying to measure how much ice is melting on nearby Greenland. According to a new study by National Science Foundation-funded researchers at The Ohio State University, the hotspot softened the mantle rock beneath Greenland in a way that ultimately distorted their calculations for ice loss in the Greenland ice sheet. This caused them to underestimate the melting by about 20 gigatons (20 billion metric tons) per year. That means Greenland did not lose about 2,500 gigatons of ice from 2003-2013 as scientists previously thought, but nearly 2,700 gigatons instead -- a 7.6 percent difference.

With ever-increasing costs of conventional healthcare, and continuing issues with insurance coverage, alternative medicine is growing in popularity. Inasmuch as it is still officially denigrated, cannabis is about as "alternative" as it gets.
This, despite no shortage of historic references to cannabis, or its extract marijuana (prepared from the dried and crushed flowers and leaves of the plant) as to its medicinal effects. Chinese Emperors Fu Hsi (2900 BC) and Shen Nung (2700 BC) are said to have touted its healing effects. Some authorities claim that the anointing oil in Exodus 30:22-25 contained cannabis, and that "cane" is a mistranslation from the original Hebrew (1450 BC). Getting more into modern times, marijuana was added to the US Pharmacopeia in 1850, and its use is indicated for an astonishingly diverse litany of illnesses.
According to this PDQ Review from the National Cancer Institute, and referring to this illustration, cannabis may lessen the progression of cancer cells. It also alleviates pain, lowers inflammation and decreases anxiety.
An oft-cited study from 1996 on mice and rats suggested that cannabinoids (any of various chemical constituents of cannabis) may have a protective effect against the development of hepatic adenoma tumors and hepatocellular carcinoma. The study also noted decreased incidences of benign tumors in other organs (mammary gland, uterus, pituitary, testis, and pancreas).
A review article (2006)—appearing in the British Journal of Pharmacology—entitled "Cannabinoids and cancer: pros and cons of an antitumour strategy" listed few cons, and displayed a largely positive picture:
Cannabinoids have the advantage of being well tolerated in animal studies and they do not present the generalized toxic effects of most conventional chemotherapeutic agents. Cannabinoids selectively affect tumor cells more than their nontransformed counterparts that might even be protected from cell death. Even if further in vivo research is required to clarify [their] action in cancer and especially to test their effectiveness in patients, the cannabinoid system represents a promising target for cancer treatment.
As to the palliative aspects of Cannabis during cancer treatment, the official version of things is... curious. According to a recent document from PubMed Health...
Several controlled clinical trials have been performed, and meta-analyses of these support a beneficial effect of cannabinoids (dronabinol and nabilone) on chemotherapy-induced nausea and vomiting (N/V) compared with placebo. Both dronabinol and nabilone are approved by the U.S. Food and Drug Administration for the prevention or treatment of chemotherapy-induced N/V in cancer patients.
Thus, the FDA has approved two drugs, which are nothing more than synthetic versions of chemicals in cannabis. In addition to the anti-nausea/vomiting properties, dronabinol is used to treat loss of appetite in people with AIDS. Analgesic properties are also claimed for both drugs.
However, owing to the bizarre stigmatization of cannabis, and the difficulty in obtaining proper clearance to study it in clinical settings, there is only a limited amount of published research available on the palliative properties of the source plant itself. Yet, anecdotal evidence of its effects is widely disseminated.
The website Surviving Mesothelioma offers inspiring stories of several people who have survived this rare form of cancer. The disease develops from cells of the mesothelium, a membrane that protects the body's major internal organs and allows them freedom of movement (for example, lung contractions). The five-year survival rate is poor—at nine percent or less—and has not improved much over the last 30 years.
The chronicle of Andy Ashcraft is quite compelling. He was diagnosed with late stage pleural mesothelioma in 2010, and given three months to a year. Far from being resigned to this fate, Andy and his wife investigated and embarked on alternative therapies, including cannabis oil. Six years later, alive and well, he really has beaten the odds, and is another one of those "anecdotal" cases of an alternative approach success.
The stigmatization of cannabis is fading, but it won't come easy. After all, lining up on the other side are Big Pharma and Big Law Enforcement. But if a therapy works, and it costs less...

An international team of researchers using the Atacama Large Millimeter/submillimeter Array and other telescopes has discovered the power source illuminating a so-called Lyman-alpha Blob -- a rare, brightly glowing, and enormous concentration of gas in the distant universe. Until now, astronomers wondered why these huge clouds of gas shined so brightly. The answer, in this example at least, appears to be two galaxies at the heart of the blob undergoing furious star formation and lighting up their surroundings. These large galaxies, which are destined to eventually merge into a single elliptical galaxy, are in the midst of a swarm of smaller galaxies. This appears to be an early phase in the formation of a massive cluster of galaxies.

Antimicrobial cutting boards. Flame-retardant carpets. Friction-resistant bearings. Engineered surfaces add value to the things we use, providing extra layers of safety, easing their operation, preserving their quality or adding utility. A new method of engineering polymer brush patterns developed at UC Santa Barbara promises to cut down processing time while adding versatility in design. Researchers are looking to greatly improve on the concept with a method of micron-scale surface chemical patterning that can not only decrease time and money spent in their manufacture, but also add versatility to their design.
