A giant neuron found wrapped around entire mouse brain Allen Institute for Brain Science A digital reconstruction of a neuron that encircles the mouse brain. Like ivy plants that send runners out searching for something to cling to, the brain’s neurons send out shoots that connect with other neurons throughout the organ. A new digital reconstruction method shows three neurons that branch extensively throughout the brain, including one that wraps around its entire outer layer. The finding may help to explain how the brain creates consciousness. Where is M13? - Home Where is M13? — A Three Dimensional Galactic Atlas!

Print Version - Five Tibetan Rites By Mary Kurus Copyright Mary Kurus 2001, All Rights Reserved Background In 1985 a book called The Ancient Secret of the Fountain of Youth written by Peter Kelder was published which for the first time fully described an exercise program for "youthing". Electromagnetic Spectrum - Introduction The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet light, X-rays and gamma-rays. You know more about the electromagnetic spectrum than you may think. The image below shows where you might encounter each portion of the EM spectrum in your day-to-day life. The electromagnetic spectrum from lowest energy/longest wavelength (at the top) to highest energy/shortest wavelength (at the bottom).

Rosie Brian – Dodgy Biology Week 8, blink and you’ll have missed it! Things with the placement were definitely heating up last week. With a member of the London office (Dr Sile Lane) visiting Brussels for an extremely tight schedule of meetings and the Evidence Matters event looming closer, my ability to organise was being put to the test. First thing on Monday was to prepare a schedule for Sile and Sofie. The task: ensure Sofie and Sile meet all the desired people with enough time to cover all topics required without rushing from one meeting point to another all the while considering Sile’s arrival and departure time…easy right? In reality, organisation would have been much easier if the contacts they were meeting hadn’t been quite so busy!

How to Calculate Your Training Heart Rate Zones Heart-rate training benefits everyone, from the beginning exerciser trying to lose weight, to individuals trying to improve their cardiovascular fitness, to the highly conditioned athlete preparing for the next competition. The key to making progress is to elevate your heart rate into the correct training zone, so your effort matches your goals. Here are seven easy-to-follow steps that will help you calculate your ideal heart-rate training zone. 1. Calculate Your Maximum Heart Rate “Digital natives” need help understanding search A report from Ethnographic Research in Illinois Academic Libraries documents research done on "digital native" college students to evaluate their skill with refining searches, evaluating search results, and navigating thorny questions of authority and trust in online sources. The researchers concluded that despite their subjects' fluency with the technology, the mental models and critical thinking they brought to bear on search results had real problems: The prevalence of Google in student research is well-documented, but the Illinois researchers found something they did not expect: students were not very good at using Google. They were basically clueless about the logic underlying how the search engine organizes and displays its results. Consequently, the students did not know how to build a search that would return good sources. (For instance, limiting a search to news articles, or querying specific databases such as Google Book Search or Google Scholar.)

WikiLeaks' CIA hacking claims: How worried should you be? - Mar. 8, 2017 Allegations that the U.S. agency has hacked into smartphones, laptops, and internet-connected TVs to spy on people around the world are enough to make anyone paranoid. But security experts are urging tech consumers to keep calm and take a few simple precautions. The document dump reveals nothing terribly new or surprising in technical terms, the experts say. Mobile spy tools have been around for years. "That the CIA hacks is like saying water is wet -- it's them doing their job," said Nicholas Weaver, senior researcher with the International Computer Science Institute at the University of California, Berkeley. The WikiLeaks publication serves as a reminder that anyone with a smartphone or another device connected to the internet is vulnerable to hacking.

Hybrid Learning: How to Reach Digital Natives by Alan Rudi “Hybrid education offers promise for engaging students who are demotivated by the lack of meaningful use of technology, and associated opportunities for skill-building and efficiency, in many lessons today.” As technology continues to advance and become more accessible around the world, experts who study how children learn are developing fresh paradigms designed to reach the new generation of students dubbed “digital natives.” The term emerged in 2001 from the work of Mark Prensky, a thought leader, speaker, writer, consultant, and game designer in the field of education and learning. Once a Teacher.... by Karen Schweitzer Looking for a great way to engage and stimulate students in even the most tedious subjects? There are many online tools, games, activities, learning aids, and even web apps designed to make learning fun. Here is a list of 20 sites to try when the new school year begins: Games and Activities History Detective Kids – Based on PBS’ History Detective television show, this site encourages children between the ages of 8 and 12 to use critical thinking, problem solving, and dramatic play while digging through the past.

Ancient technique can dramatically improve memory, research suggests A memory technique invented by the ancient Greeks can make dramatic and long-lasting improvements to a person’s power of recall, according to research that suggests many of us have extensive untapped memory reserves. After spending six weeks cultivating an internal “memory palace”, people more than doubled the number of words they could retain in a short time period and their performance remained impressive four months later. The technique, which involves conjuring up vivid images of objects in a familiar setting, is credited to the Greek poet Simonides of Ceos, and is a favoured method among so-called memory athletes. The study also revealed that after just 40 days of training, people’s brain activity shifted to more closely resemble that seen in some of the world’s highest ranked memory champions, suggesting that memory training can alter the brain’s wiring in subtle but powerful ways. The answer, perhaps surprisingly, was no.

The Best Web 2.0 Applications For Education In 2011 — So Far I usually just do a year-end list on Web 2.0 Applications For Education and many other topics, but it gets a little crazy having to review all of my zillion posts at once. So, to make it easier for me — and perhaps, to make it a little more useful to readers — I’m going to start publishing mid-year lists, too. These won’t be ranked, unlike my year-end “The Best…” lists, and just because a site appears on a mid-year list doesn’t guarantee it will be included in an end-of-the-year one. But, at least, I won’t have to review all my year’s posts in December… As usual, in order to make this list, a site had to be:
