Tl;dr: Experimentalists are bringing increasingly massive systems into quantum states. They are now close to masses where they might be able to just measure what happens to the gravitational field.

Quantum effects of gravity are weak, so weak they are widely believed to not be measurable at all. Freeman Dyson indeed is fond of saying that a theory of quantum gravity is entirely unnecessary, arguing that we could never observe its effects anyway. Theorists of course disagree, and not just because they’re being paid to figure out the very theory Dyson deems unnecessary. Measurable or not, they search for a quantized version of gravity because the existing description of nature is not merely incomplete – it is far worse, it contains internal contradictions, meaning we know it is wrong.

Take the century-old double-slit experiment, the prime example for quantum behavior. A single electron that goes through the double-slit is able to interact with itself, as if it went through both slits at once. Its behavior is like that of a wave which overlaps with itself after passing an obstacle. And yet, when you measure the electron after it went through the slit it makes a dot on a screen, like a particle would. The wave-like behavior again shows up if one measures the distribution of many electrons that passed the slit. This and many other experiments demonstrate that the electron is neither a particle nor a wave – it is described by a wave-function from which we obtain a probability distribution, a formulation that is the core of quantum mechanics.

“When the Rosetta spacecraft deployed the Philae lander to land on a comet last November, the world held its breath. … Little surprise too that space is back on the design agenda as a primary source of inspiration. Visiting Design Miami/Basel in June, it was obvious that the “Philae effect” was having an impact much closer to home.”

Elephants are long-lived, and rather large. Given their size and longevity, scientists have pondered what protects them from cancer for a long time. Thanks to new research, we now know.

A mystery unlocked

Cancer is a big problem. A staggering 1 in 2 people born after 1960 in the UK are predicted to develop cancer at some point in their lifetime. We may be living longer, but the extra years are coming with a raised cancer risk. We may be getting better at treatment, but we’re still finding out exactly what causes it, and how we can prevent it from being a danger altogether.

Aging is 100% genetic, the reason you go from infant to child to adult to old age.

We need to be scrutinizing Progeria, and the case of the girl who died at 20 and was stuck at the age of a toddler, for the key to the genes that will pause aging. While nanotechnology advances parallel with the cure for all diseases.

Once a bucket of genes linked to aging is removed, the lifespan of cells increases significantly, American scientists discovered during ten years of meticulous research, stressing that the results could be applied to humans.
