‘Mind Uploading’ & Digital Immortality May Be Reality By 2030 : Dr. Michio Kaku
There are two major questions surrounding the concept of mind uploading. There is the question of feasibility: Can we build a model of a brain complete enough to allow a conscious mind to emerge? The other question is concerned with identity. Some people argue that, if a copy of a conscious mind is identical by all measures (ignoring the fact that one is biological and the other is neuromorphic software/hardware)...
A new way to make laser-like beams using 1,000x less power
With precarious particles called polaritons that straddle the worlds of light and matter, University of Michigan researchers have demonstrated a new, practical and potentially more efficient way to make a coherent laser-like beam.
They have made what's believed to be the first polariton laser that is fueled by electrical current as opposed to light, and also works at room temperature, rather than way below zero.
Those attributes...
Just Add Water, and Silicon Folds Into Origami Shapes
Researchers created microscopic cubes, pyramids, half soccer-ball-shaped bowls
and long triangular Toblerone-like structures, all of which fold themselves when
wetted by a drop of water. Credit: A. Legrain, et. al, University of Twente
Remember those elementary geometry lessons that involved cutting out a pattern from a worksheet and folding along the dotted lines to create a cube, cone or cylinder? Well, fully grown scientists...
3000 year old trousers discovered in Chinese grave oldest ever found
A team of researchers working in the ancient Yanghai graveyard in China's Tarim Basin has uncovered what appears to be the earliest example of trouser wearing. The research team has published a paper in the journal Quaternary International describing the pants and why they were likely developed to assist with riding horses.
The Tarim Basin in western China is host to the famous Yanghai tombs, a large ancient burial...
Scientists find stronger 3-D material that behaves like graphene
Scientists at Oxford, SLAC, Stanford and Berkeley Lab have discovered
that a sturdy 3-D material, cadmium arsenide, mimics the
electronic behavior of 2-D graphene. This illustration depicts fast-moving,
massless electrons inside the material. The discovery could lead to new
and faster types of electronic devices. Credit: Greg Stewart/SLAC
Scientists have discovered a material that has the same extraordinary electronic properties...
Five or more blistering sunburns before age 20 may increase melanoma risk by 80 percent

The risk of developing the most deadly form of skin cancer, melanoma, was more closely related to sun exposure in early life than in adulthood in young Caucasian women, according to a study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
"Our results suggest that sun exposures...
World's best thermometer made from light

University of Adelaide physics researchers have produced the world's most sensitive thermometer – three times more precise than the best thermometers in existence.

Tractor beam that can move objects
A TRACTOR beam familiar from sci-fi classics such
as Star Wars and Star Trek, has become fact not fiction
Physicists at Dundee University have created a functioning acoustic tractor beam, using energy from an ultrasound array to exert force behind an object and pull it to the energy source.
"This is the first time anyone has demonstrated a working acoustic tractor beam and the first time such a beam has been used to move anything bigger...
