Vaping Criminal Probe Announced By FDA As Illnesses Rise To 530

Slashdot - Science - Hace 2 horas 8 mins
The FDA has revealed a criminal investigation into the outbreak of vaping-related lung illnesses, which have risen to 530 across 38 states, according to the CDC. The Washington Post says there have been seven confirmed deaths from these illnesses so far. CNET reports: The FDA reportedly said it isn't seeking prosecution for ill people who've vaped cannabis and come forward with information. "The focus is on the supply chain," Mitch Zeller, director of the FDA's Center for Tobacco Products, told the Post. "We're very alarmed about products containing THC." Suspicion has recently turned to chemical dilutants, or "cutting agents," found in some black market THC vaping oils. The FDA has collected more than 150 samples from patients across the country and is now analyzing them for the presence of cutting agents and other substances. According to the CDC, more than half the patients are under 25, with two-thirds between 18 and 34, and 16% under 18.

North America Has Lost 3 Billion Birds in 50 Years

Slashdot - Science - Hace 5 horas 22 mins
Slowly, steadily and almost imperceptibly, North America's bird population is dwindling. From a report: The sparrows and finches that visit backyard feeders number fewer each year. The flutelike song of the western meadowlark -- the official bird of six U.S. states -- is growing more rare. The continent has lost nearly 3 billion birds representing hundreds of species over the past five decades, in an enormous loss that signals an "overlooked biodiversity crisis," according to a study from top ornithologists and government agencies. This is not an extinction crisis -- yet. It is a more insidious decline in abundance as humans dramatically alter the landscape: There are 29 percent fewer birds in the United States and Canada today than in 1970, the study concludes. Grassland species have been hardest hit, probably because of agricultural intensification that has engulfed habitats and spread pesticides that kill the insects many birds eat. But the victims include warblers, thrushes, swallows and other familiar birds. "That's really what was so staggering about this," said lead author Ken Rosenberg, a senior scientist at the Cornell Lab of Ornithology and American Bird Conservancy. "The generalist, adaptable, so-called common species were not compensating for the losses, and in fact they were experiencing losses themselves. This major loss was pervasive across all the bird groups."

Appreciating the classical elegance of time crystals

Science Daily - Hace 7 horas 5 mins
Structures known as 'time crystals' -- which repeat in time as conventional crystals repeat in space -- have recently captured the interest and imagination of researchers across disciplines. The concept has emerged from the context of quantum many-body systems, but physicists have now developed a versatile framework that clarifies connections to classical works dating back nearly two centuries, thus providing a unifying platform to explore seemingly dissimilar phenomena.

Scientists identify a possible new treatment for diabetic retinopathy

Science Daily - Hace 7 horas 41 mins
About 1 in 3 diabetic patients develops diabetic retinopathy (DR), which can impair vision and lead to blindness. A new study provides clear evidence that high glucose increases the levels of enzymatic precursor -- lysyl oxidase propeptide (LOX-PP) -- that promotes cell death, which was verified in an animal model of diabetes. These findings may help develop novel DR treatments by targeting LOX-PP or its metabolites.

Let there be light: Synthesizing organic compounds

Disrupting key protein alters biological rhythms in water flea

Science Daily - Hace 8 horas 34 mins
The E75 protein is a key regulator of some biological rhythms through interactions with nitric oxide. Suppression of E75 results in longer molt cycles and reduced numbers of offspring in the water flea, Daphnia magna. The work also raises questions about the ability of nitric oxide from environmental sources to disrupt biological rhythms that are critical to population sustainability.

Biologists untangle growth and defense in maize, define key antibiotic pathways

Science Daily - Hace 8 horas 34 mins
Studying the complex layers of immunity in maize, a staple for diets around the world, scientists have identified key genes that enable surprisingly diverse antibiotic cocktails that can be produced as defensive blends against numerous disease agents. Biologists describe how they combined an array of scientific approaches to clearly define 6 genes that encode enzymes responsible for the production of key maize antibiotics known to control disease resistance.
