Bipolar disease in children, adolescents: Discharge rates much higher in the US compared to UK

Science Daily - Thu, 22/05/2014 - 2:50pm
A significantly higher discharge rate for pediatric bipolar in children and adolescents aged 1-19 years has been found in the US compared to England. "The finding that the disparity between US and English discharge rates for PBD is markedly greater than the disparity for child psychiatric discharge rates overall, and for adult rates for bipolar disorder, is potentially important. However, the study design does not allow us to answer the question whether US clinicians are too liberal in assigning the diagnosis of bipolar disorder to youth or, alternatively, whether English clinicians fail to recognize or diagnose these illnesses. It is clear that the reasons for the disparity in the case of PBD warrant further study," the lead author says.

Alcoholism treatment: Kappa opioid receptors a new target

Science Daily - Thu, 22/05/2014 - 2:50pm
The list of brain receptor targets for opiates reads like a fraternity: Mu Delta Kappa. The mu opioid receptor is the primary target for morphine and endogenous opioids like endorphin, whereas the delta opioid receptor shows the highest affinity for endogenous enkephalins. The kappa opioid receptor is very interesting, but the least understood of the opiate receptor family.

European farmers: Importance of adapting to climate change

Science Daily - Thu, 22/05/2014 - 2:49pm
Farmers in Europe will see crop yields affected as global temperatures rise, but that adaptation can help slow the decline for some crops. Research reveals that farmers in Europe will see crop yields affected as global temperatures rise, but that adaptation can help slow the decline for some crops. For corn, the anticipated loss is roughly 10 percent, the research shows. Farmers of these crops have already seen yield growth slow down since 1980 as temperatures have risen, though other policy and economic factors have also played a role.

First broadband wireless connection ... to the moon: Record-shattering Earth-to-Moon uplink

Science Daily - Thu, 22/05/2014 - 2:49pm
Scientists have prepared new details and the first comprehensive overview of the on-orbit performance of their record-shattering laser-based communication uplink between the moon and Earth, which beat the previous record transmission speed last fall by a factor of 4,800.

There is still hope for the climate: Regional cures for planetary fever

Science Daily - Thu, 22/05/2014 - 2:48pm
There is still hope for the climate, even if a world-wide climate accord proves to be unattainable. A new report shows that regional measures can hold the global rise in temperature within the two-degree limit.

Devastating human impact on the Amazon rainforest revealed

Science Daily - Thu, 22/05/2014 - 2:48pm
The human impact on the Amazon rainforest has been grossly underestimated according to an international team of researchers. They found that selective logging and surface wildfires can result in an annual loss of 54 billion tons of carbon from the Brazilian Amazon, increasing greenhouse gas emissions. This is equivalent to 40% of the yearly carbon loss from deforestation -- when entire forests are chopped down.

Stem-cell research: A new genetic switching element

Science Daily - Thu, 22/05/2014 - 2:48pm
Every cell contains stored hereditary information, encoded in the sequence of nucleobases that make up its DNA. However, in any given cell type, only a fraction of this information is actually used. Which genes are activated and which are turned off is in part determined by a second tier of information which is superimposed on the nucleotide sequences that provide the blueprints for protein synthesis. This so-called epigenetic level of control is based on the localized, and in principle reversible, attachment of simple chemical tags to specific nucleotides in the genome. Slight modifications in genome sequences play a crucial role in the conversion of pluripotent stem cells into various differentiated cell types.

Marriage of convenience with a fungus: Equal for all plants, or just some?

Science Daily - Thu, 22/05/2014 - 2:48pm
Thanks to a fungus, the medicinal plant ribwort plantain gains a higher concentration of the defensive compound catalpol. The increase in catalpol gives the plant better protection against pests. In the study, the research team worked with arbuscular mycorrhizal fungi. These are known to colonize the roots of land plants. The plants benefit from this because the fungus provides them with nutrients and minerals. However, are the impacts of this marriage of convenience with the fungus on plant chemistry equal for all plants? That is what the researchers wanted to find out.

5 Years Later, 'Do Not Track' System Ineffective

Slashdot - Thu, 22/05/2014 - 2:12pm
An anonymous reader sends this excerpt from ComputerWorld: "In 2009, a few Internet privacy advocates developed an idea that was supposed to give people a way to tell websites they don't want to be monitored as they move from website to website. The mechanism, which would eventually be built into all the major browsers, was called Do Not Track. ... But today, DNT hangs by a thread, neutered by a failure among stakeholders to reach agreement. Yes, if you turn it on in your browser, it sends a signal in the form of an HTTP header to Web companies' servers. But it probably won't change what data they collect. That's because most websites either don't honor DNT — it's currently a voluntary system — or they interpret it in different ways. Another problem — perhaps the biggest — is that Web companies, ad agencies and the other stakeholders have never reached agreement on what "do not track" really means."
