Data from end of the last ice age illuminate the precarious nature of global ocean chemistry
The ocean the Titanic sailed through just over 100 years ago was very different from the one we swim in today. Global warming is increasing ocean temperatures and harming marine food webs. Nitrogen run-off from fertilizers is causing coastal dead zones. A McGill-led international research team has now completed the first global study of changes that occurred in a crucial component of ocean chemistry, the nitrogen cycle, at the end of the last ice age. The results of their study confirm that oceans are good at balancing the nitrogen cycle on a global scale. But the data also shows that it is a slow process that may take many centuries, or even millennia, raising worries about the effects of the scale and speed of current changes in the ocean.
Study uncovers secrets of biological soil crusts
They lie dormant for years, but at the first sign of favorable conditions they awaken. This sounds like the tagline for a science fiction movie, but it describes the amazing life-cycles of microbial organisms that form the biological soil crusts (BSCs) of Earth's deserts. Now a research team with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) has reported a unique molecular-level analysis of a BSC cyanobacterium responding to the wetting and drying of its environment. The results hold implications for land management, improved climate change models, and a better understanding of carbon cycling in soil microbial communities and how changes in global temperatures impact Earth's deserts.
Study explains decades of black hole observations
(Phys.org) —A new study by astronomers at NASA, Johns Hopkins University and Rochester Institute of Technology confirms long-held suspicions about how stellar-mass black holes produce their highest-energy light.

Scientists discover key mechanism that boosts signalling function of neurons in the brain
(Medical Xpress)—Locating a car that's blowing its horn in heavy traffic, channel-hopping between football and a thriller on TV without losing the plot, and not forgetting the start of a sentence by the time we have read to the end – we consider all of these to be normal everyday functions. They enable us to react to fast-changing circumstances and to carry out even complex activities correctly. For this to work, the neuron circuits in our brain have to be very flexible. Scientists working under the leadership of neurobiologists Nils Brose and Erwin Neher at the Max Planck Institutes of Experimental Medicine and Biophysical Chemistry in Göttingen have now discovered an important molecular mechanism that turns neurons into true masters of adaptation.
Nanopatch: Syringe and needle replacement unveiled at TEDGLobal Conference

New findings regarding DNA damage checkpoint mechanism in oxidative stress
In current health lore, antioxidants are all the rage, as "everybody knows" that reducing the amount of "reactive oxygen species"—cell-damaging molecules that are byproducts of cellular metabolism—is critical to staying healthy. What everyone doesn't know is that our bodies already have a complex set of processes built into our cells that handle these harmful byproducts of living and repair the damage they cause.
Scientists identify neurons that control feeding behavior in Drosophila
Scientists at the University of Massachusetts Medical School have developed a novel transgenic system which allows them to remotely activate individual brain cells in the model organism Drosophila using ambient temperature. This powerful new tool for identifying and characterizing neural circuitry has lead to the identification of a pair of neurons – now called Fdg neurons – in the fruit fly that decide when to eat and initiate the subsequent feeding action. Discovery of these neurons may help neurobiologists better understand how the brain uses memory and stimuli to produce classically conditioned responses, such as those often associated with phobias or drug tolerance. The study appears in the journal Nature.

Could 19th-century vets provide lessons for farm animal health policy today?
When Foot and Mouth Disease broke out in 2001, while consumers may have been shocked to see pyres of burning cattle on their television screens, few were surprised that the UK Government had intervened in the crisis. Nowadays we assume farm animal health is a legitimate area of interest for the state. But 150 years ago the veterinary profession had to develop new areas of understanding and practice to enable this to happen, and a leading academic in the history of human and animal health argues that this could give us some pointers for how we approach such issues today.
