Mysterious object unlike anything astronomers have seen before
A team mapping radio waves in the Universe has discovered something unusual that releases a giant burst of energy three times an hour, and it’s unlike anything astronomers have seen before. The team who discovered it think it could be a neutron star or a white dwarf—collapsed cores of stars—with an ultra-powerful…

T cells block nerve cell regeneration with age, but can be reversed – mice study
New research in mice shows T cells prevent damaged nerve cells from regenerating due to a reversible, ageing-related mechanism.

Holography without Lasers: Hand-drawn Holograms (1999)
I've stumbled across a technique for drawing holograms directly upon a plastic plate by hand. It sounds impossible, but I've been sitting on the livingroom sofa making holographic images of floating polyhedra, words, 3D starfields, opaque objects, etc. No laser, no isolation table, no darkroom, no expensive film…

Einstein-Bohr debate settled once and for all
In Steven Pinker’s guest post from last week, there’s one bit to which I never replied. Steve wrote: After all, in many areas Einstein was no Einstein. You [Scott] above all could speak…

New study shows highly creative people’s brains work differently from others'
A new study led by UCLA Health scientists shows highly creative people’s brains appear to work differently from others;, with an atypical approach that makes distant connections more quickly by bypassing the “hubs” seen in non-creative brains.

Oxidation makes tea black
Oxidation radically alters everything we perceive in food. It changes the flavor, aroma, color, and texture of everything we eat and drink. Without oxidation, tea would taste unbearably bitter. Oxidation is what unlocks tea’s hidden flavors by removing bitter compounds and transforming flavorless proteins into…

How do palm trees survive hurricanes? (2017)
The destructive force of typhoons and hurricanes are no joking matter. Human structures are torn to shreds and flooded in the blink of an eye. It is devastating to say the least. With all of this destruction, one must wonder how native flora and fauna have coped with such forces over millions of years. The true…

Physicists discover a “family” of robust, superconducting graphene structures
MIT physicsts identified new multilayered configurations of graphene that can be twisted and stacked to elicit robust superconductivity at low temperatures. The study establishes these configurations as the first known “family” of multilayer magic-angle superconductors.
