We’re closer to mind-reading than you may think

mind_controlIf you thought mind-reading was impossible, think again. Recent discoveries by the University of Minnesota show that it is within reach.

The Economist reports that Prof. Bin He and his colleagues were able to give test subjects the ability to control a digital helicopter through a virtual, three-dimensional space using the power of thought. The brain control was registered using electrodes attached to the subjects’ scalps. The discovery was originally published in the Public Library of Science.

Knowledge is power

knowledgeIn learning to maximise the power of the mind, Tony Buzan has inspired thousands, sharing his secrets in The Mind Map Book

Mind Mapping is both a creative and effective way of thinking; it’s a tool used by top global organisations such as NASA, Walt Disney, Microsoft, Harper Collins, Vodafone and IBM. Created by Tony Buzan, with the help of his brother Barry Buzan in the 1960s, their work, The Mind Map Book, promises to unleash your brain’s real potential by tapping into that very force field that’s locked in our heads, waiting to be opened, explored and nurtured towards putting thoughts into action. 

Separated For 20 Million Years: Blind Beetle Clarifies Questions

Blind-BeetleOne of the smallest ever cave-dwelling ground beetles (Carabidae), has recently been discovered in two caves in the Rhodopi Mountains, Bulgaria, and described under the name Paralovricia beroni. The beetle is completely blind and is only 1.8-2.2 mm long. The study was published in the open access journal ZooKeys.

World-record 'Split Magnet' Makes Its Debut

magnetA custom-built, $2.5 million "split magnet" system with the potential to revolutionize scientific research in a variety of fields has made its debut at the National High Magnetic Field Laboratory at Florida State University.

The world-record magnet is operating at 25 tesla, easily besting the 17.5 tesla French record set in 1991 for this type of magnet. ("Tesla," named for early 20th-century inventor and engineer Nikola Tesla, is a measurement of the strength of a magnetic field.) In addition to being 43 percent more powerful than the previous world best, the new magnet also has 1,500 times as much space at its center, allowing room for more flexible, varied experiments.

Sea Urchins Cannot Control Invasive Seaweeds

Sea-UrchinsExotic marine species, including giant seaweeds, are spreading fast, with harmful effects on native species, and are increasingly affecting the biodiversity of the Mediterranean seabed. Some native species, such as sea urchins (Paracentrotus lividus), can fight off this invasion, but only during its early stages, or when seaweed densities are very low.

War among evolutionists!

chimp-thinkingThere is a war among evolutionists. Most evolutionists are Neo-Darwinian, believing in gradual change from one form of life to another, but a good growing minority of evolutionists believe in Punctuated Equilibrium which teaches life forms changed suddenly from one form into another through massive random genetic mutations caused by massive radiation.

God's Big Bang

bigbang_erasLast month saw miniature versions of the "Big Bang" being created within the Large Hadron Collider, based under the Alps at CERN. Scientists are cheering at the achievement, which generated temperatures of over 10 trillion degrees, a million times hotter than the centre of the Sun; this achievement opens up a new era in particle physics research.

Dr David Evans, a member of the UK team who worked on the experiment was thrilled by the success, "At these temperatures even protons and neutrons – which make up the nuclei of atoms – melt, resulting in a hot dense soup of quarks and gluons known as a quark-gluon plasma."

The Celestial Computers of Ancient Greece

vallianatosJust before Easter 1900, Greek sponge-fishers were on their way to the waters of Tunisia when a violent storm threw their boats to Antikythera, a tiny island located north of Crete in the Aegean.

After the storm, the sponge-fishers explored the waters of Antikythera for sponges. One of the divers, Elias Stadiatis, discovered the remnants of an ancient ship full of statues - horses, men, women and vases.

Body Scanners may cause cancer

full-body-scannersAt a time when airports around the globe are planning to install full body scanners to maximise security, the US Congress has been warned that the X-ray imaging could increase the risk of skin cancer in air passengers.

Before the Photo Camera , There Was the Camera Obscura

Camera_obscuraThe first camera obscura was built by an Iraqi scientist named Abu Ali Al-Hasan Ibn al-Haitham, born in Basra(965-1039 AD), known in the West as Alhacen or Alhazen, who carried out practical experiments on optics in his Book of Optics. His method of experiments is then used to establish what is know kknown as 'scientific method,' a couple of centuries before the work of Isaac Newton.

Discovery that quasars don't show time dilation mystifies astronomers

This X-ray image shows the quasar PKS 1127-145, a highly luminous source of X-rays and visible light located about 10 billion light years from Earth. Its X-ray jet extends at least a million light years from the quasar.

The phenomenon of time dilation is a strange yet experimentally confirmed effect of relativity theory. One of its implications is that events occurring in distant parts of the universe should appear to occur more slowly than events located closer to us. For example, when observing supernovae, scientists have found that distant explosions seem to fade more slowly than the quickly-fading nearby supernovae.
