As if space travel was not already filled with enough dangers, a new study out today in the journal PLOS ONE shows that cosmic radiation – which would bombard astronauts on deep space missions to places like Mars – could accelerate the onset of Alzheimer's disease.

Our observations prove that innovative tool-related problem-solving is within this species’ cognitive resources. As it is unknown for tools to play a major role in this species’ ecology, this strengthens the view that tool competences can originate on general physical intelligence, rather than just as problem-specific ecological solutions (see discussions in [2,4]). The precise cognitive operations underlying such innovations are still unknown, but future studies may continue to unravel them by modifying the tasks, and controlling the developmental history and pre-experimental experience across different groups of subjects.
Carnegie Mellon university researchers have developed a surveillance system that can not only recognize human activities but can also predict what might happen next.
Researchers, through the Army-funded research dubbed Mind's Eye, have created intelligent software that recognizes human activities in video and can predict what might just happen next; sounding an alarm if it detects anomalous behavior.
This short-cut guide to setting up a scientific paper is simple, effective and intuitive. Sure, it was designed with ecology in mind, but it should apply to most scientific disciplines. It appeals to most of our students, and we have both been asked for copies by other supervisors over the years. Our original intention was to write a paper about writing papers to flesh out the full Méthode, but that has yet to happen.
Therefore, for the benefit of the up-and-comings (and perhaps to a few of those longer in tooth), behold La Méthode Brookoise for writing papers:

Coining the useful term "patent monetization entity" (as a replacement for "patent troll," "nonpracticing entity," and "patent assertion entity" -- all terms with either social or technical issues), the scholars have concluded that "lawsuits filed by patent monetizers have increased significantly over the five-year period." Not only has the number of cases increased, but so has the proportion of these non-product-related litigants, from 22 percent to 40 percent of cases filed. They found that four of the top five patent litigants in America exist solely to file lawsuits.

Computer models have accurately forecast conditions on Mars and are valid predictors of climate change on Earth, U.S. and French astronomers said on Tuesday.
These computer programs predicted Martian glaciers and other features on Earth's planetary neighbor, scientists found.
"Some public figures imply that modeling of global climate change on Earth is 'junk science,' but if climate models can explain features observed on other planets, then the models must have at least some validity," lead researcher William Hartmann of the Planetary Science Institute said in a statement.
The temperature in the Fukushima Daiichi Unit 4 spent fuel pool never exceeded 90 degrees C and the level in the pool never fell below the top of the used fuel that was stored there. The Chairman of the US Nuclear Regulatory Commission and the people who supported his testimony to Congress on the afternoon of March 16, 2011 were dead wrong.
Those are the conclusions that should have been announced upon completion of a paper titled _Study of Fukushima Daiichi Nuclear Power Station Unit 4 Spent-Fuel Pool_.
Be that as it may. As a layperson, I might question the wisdom in storing tons and tons of radioactive and heat-generating spent fuel for extended periods of time in an on-premise pool. But what do I know?

It is known that childhood experience influences brain development but the only evidence scientists have had for this has usually come from extreme cases such as children who had been abused or suffered trauma. Martha Farah, director of the centre for neuroscience and society at the University of Pennsylvania, who led the latest study, wanted to find out how a normal range of experiences in childhood might influence the development of the brain.
Farah took data from surveys of home life and brain scans of 64 participants carried out over the course of 20 years. Her results, presented on Sunday at the annual meeting of the Society for Neuroscience in New Orleans, showed that cognitive stimulation from parents at the age of four was the key factor in predicting the development of several parts of the cortex – the layer of grey matter on the outside of the brain – 15 years later.
Doctors and government health officials should set limits, as they do for alcohol, on the amount of time children spend watching screens – and under-threes should be kept away from the television altogether, according to a paper in an influential medical journal published on Tuesday.
Do you have a pet parrot? Would you like to learn more about your parrot's behaviour? So would we!
Researchers at the University of Guelph (Canada) and the University of Utrecht (Netherlands) are seeking parrot owners or caretakers who are willing to participate in an online survey focusing on their parrot's behaviour and living environment. We are interested in all psittacine species: from budgerigars, to cockatoos, to macaws – and all species in between. We would like to collect information on both healthy, problem-free birds and those with health or behaviour problems. We invite you, as the owner of a pet parrot or parakeet, to participate in this international research project! You can be assured that your important contribution will help to improve the welfare of captive parrots. And, who knows? Maybe you'll learn some new and interesting things about your own parrot in the process…
