Nitrogen pollution changing Rocky Mountain National Park vegetation
A new study indicates air pollution in the form of nitrogen compounds emanating from power plants, automobiles and agriculture is changing the alpine vegetation in Rocky Mountain National Park.

23:20Scientists have discovered that environmental factors critically influence the growth of a type of stem cell--called an iPS cell -- that is derived from adult skin cells. This discovery offers newfound understanding of how these cells form, while also advancing science closer to stem cell-based therapies to combat disease.
-
23:20The widely used diabetes drug metformin comes with a rather unexpected and alluring side effect: it encourages the growth of new neurons in the brain. The study also finds that those neural effects of the drug also make mice smarter.
-
23:20Researchers in India are developing a new technology that will prevent truck drivers and other road users from using their cell phones while driving. The technology based on RFIDs could also be integrated with police traffic monitoring.

23:20Feeling full involves more than just the uncomfortable sensation that your waistband is getting tight. Investigators have now mapped out the signals that travel between your gut and your brain to generate the feeling of satiety after eating a protein-rich meal. Understanding this back and forth loop between the brain and gut may pave the way for future approaches in the treatment and/or prevention of obesity.

Bioengineers discover single cancer cell can produce up to five daughter cells
Conventional biology expects the process of mammalian cell division, mitosis, to occur by the equal partition of a mother cell into two daughter cells. Bioengineers at UCLA Engineering have developed a platform that mechanically confines cells, simulating the in vivo three-dimensional environments in which they divide. Upon confinement they have discovered that cancer cells can divide a large percentage of the time into three or more daughter cells instead. -
22:24Living in the guts of worms are seemingly innocuous bacteria that contribute to their survival. With a flip of a switch, however, these same bacteria transform from harmless microbes into deadly insecticides.

22:24Stick a shovel in the ground and scoop. That's about how deep scientists need to go in order to find evidence for ancient life on Mars, if there is any to be found, a new study suggests. That's within reach of Curiosity, the Mars Science Laboratory rover expected to land on the Red Planet next month.

22:24(Phys.org) -- Adding to the onslaught of vendor prototypes of wearable heads-up display models is Japan based Olympus with its Thursday announcement of the Meg4.0, a glasses mounted display—yes, it needs to be fitted on eyeglasses—with technology that Olympus hopes will differentiate it from other vendors' attempts. MEG4.0, a tiny wearable display weighing in at 30g, can be fitted on most glasses. The wearer connects it to a smartphone with GPS, via Bluetooth 2.1. The MEG4.0 comes with QVGA resolution (320×240) with a 10cd/m2 – 2,000 cd/m2 brightness, and built in accelerometer.

22:24A University of Saskatchewan-led international research team has discovered that aerosols from relatively small volcanic eruptions can be boosted into the high atmosphere by weather systems such as monsoons, where they can affect global temperatures. The research appears in the July 6 issue of the journal Science.
