A new study investigated the circumstances under which a 15-year-old kitesurfing male died after a tiger shark attacked him in the South Pacific. Their analysis suggests that attack took place mostly likely because the kitesurfer’s motion was confused by the shark with a bird overtaking the water. In light of other similar shark attack cases, the researchers advise any kitesurfing in waters known to harbor sharks should be made with extreme care.
Scientists have found a way to transform cigarette buds into a material which stores energy cheap and efficiently. The material outperforms both commercial and prototypical materials made from graphene and carbon nanotubes and may be eventually added into computers, smart phones or wind turbines.
Scientists have managed to make the coloring of a butterfly species evolve from brown to purple in just six generations. This study shows that even complex coloring mechanisms can undergo fast rearrangements, potentially adapting quickly to outside stimuli.
Using approximate computational methods, researchers at the SHARP Corporation and Kyoto Universities have identified a new battery material that can retain charge even after a massive amount of charge and discharge cycles. Experiments suggest that the new lithium ion battery that uses a co-substitute of lithium iron phosphate as the cathode can retain 70% of its charge even after 25,000 cycles. In comparison, a typical laptop battery can only retain 80% of its initial charge after 300 cycles.
Heisenberg’s uncertainty principle makes quantum physics nasty. There’s no reason why we can’t get all along, though. A novel technique explores how it may be possible to know both position and momentum for a particle. No laws of physics were broken. I promise!
Researchers at University of Sheffield demonstrate a perovskite spray-on solar cell for the first time. Also, this is the first time rated efficiency for a spray-on solar cell tops two figures in efficiency, marking an important milestone and breakthrough in the field.
Designs for a device called a “microwave thruster” were proposed in 2006. While the device was physically sound and followed the principles of relativity, it has been dismissed by researchers who claimed that such a functioning device would defy the law of conservation of momentum. A team from NASA set out to trial the device and see if it works; lo and
I remember when once upon a time, wi-fi could barely reach from one room to the other. It wasn’t even regarded as a serious technology by some back then – but oh my, how times have changed! Now, wi-fi is almost ubiquitous in the developed world, but the problem still remains the same – the range. Now, the IEEE (Institute
Computer games could be the key to treating elderly people who have been diagnosed with depression, but who aren’t responding to conventional treatment. A new study has shown that playing a certain type of computer games was more effective at reducing symptoms of depression than the “gold standard” – the antidepressant drug escitalopram. Recently, we’ve been bombarded about the positive effects that video
The new study concludes that an aspirin a day for middle-aged people could save 130,000 lives over 20 years in Britain alone, by reducing cancer risk. Aspirin was most effective in cutting cancer risk in people from 50 to 64, and in order for the effects to be felt to the fullest, people should take 1 aspirin per day for 10
Gaia is an unmanned space observatory of the European Space Agency (ESA) which aims to catalog approximately 1 billion astronomical objects (mostly stars), about 1% of the Milky Way population. Gaia will provide a trove of valuable and spectacular data, including a precise three-dimensional map of astronomical objects throughout the Milky Way and map their motions. We were telling you
Austrlian researchers have successfully developed transparent, ultra-thin, foldable solar cells.
The Aboriginal Martu people have been hunting kangaroos and sand monitor lizards for over 2,000 years. During this time, the natives have not only lived sustainably, but also became unwilling conservationists helping kangaroo populations grow by sparking wild fires that help them catch lizards, a study by researchers at University of Utah found. In other remote areas where this subsistence practice ceased,
Scientists successfully predicted human happiness using a mathematical equation – you too can use the smartphone app they developed and be a part of the experiment.
The old adage goes ‘practice makes perfect’, and while we all know there is truth in it, at some point practice ceases to become the driving factor towards excellence, at least if we’re to judge from the recent findings of a group of psychologists who studied how people acquire skills and become experts at what they do. There’s quite a
The Cariboo Regional District has released troubling video of what can already be called a full-scale environmental disaster following the release of five million cubic meters of effluent from a tailing pond at the Mount Polley gold and copper mine near Likely, B.C., on Monday. Mount Polley is an open pit copper/gold mine with a developing underground project, located in
Most University professors still rely on passive lectures to get their subject across. A meta-study which analyzed 225 studies found that active teaching – lectures that actively engage students and make the learning experience two-way – improves grades and significantly reduces fail rates. The findings add to an already body of literature that suggests the current dominant teaching model is
Beijing and the surrounding area will ban coal by the end of 2020, the official Xinhua news agency said on Monday. It’s not much, but it’s a start – about 1% of the Chinese population lives in that area, and over one quarter of the energy they use comes from coal, so banning it is definitely a good signal. Fuel
Researchers have found a cheap and quick way of producing peptides in a laboratory. Producing one of the body’s natural defenses against cancer and then implanting it into patients can prove pivotal in the fight against cancer.
Scientists previously misclassified a golden bat which lives in Bolivia. This new study reemphasizes the importance of museum specimens, which can be used to draw new information about species thought to be understood.
