The Einstein Effect: People Trust Nonsense More if They Think a Scientist Said It
Discontinuity is the antithesis of inspiration. The complexity of the present time seems to demand an unveiling of our hopes if we are going to survive. This life is nothing short of a blossoming osmosis of mythic understanding. Sounds like bullshi

Super-elastic alloy is first known metal to get springier as it heats up
City University of Hong Kong researchers have accidentally discovered a first-of-its-kind alloy that retains its stiffness instead of softening as the temperature rises. Indeed, high-entropy Elinvar appears to get stiffer and springier as temperatures approach 1,000 K (727°C, 1,341 °F). No other known metals have been found to behave this way.
In addition to the Elinvar effect, this metal also displays an elastic limit of about 2 percent at room temperature. You can see the extraordinary spring-back power of this high-entropy Elinvar alloy demonstrated in a room-temperature ball bearing drop test in the video.

American Woman Appears to Be Entirely Cured of HIV After Unique Medical Treatment
Ten years ago, an unnamed American woman was diagnosed with HIV. Like the tens of thousands of people who test positive in the US each year, she faced a lifetime of anti-retroviral therapies to keep the virus from obliterating her immune system.

Around 450 BCE, Anaxagoras of Clazomenae had some time to think. The Greek mathematician was in prison for claiming the sun was not a god, but rather an incandescent rock as big as the Peloponnese peninsula. A philosopher who believed that “reason rules the world,” he used his incarceration to grapple with a now-famous math problem known as squaring the circle: Using a compass and a straightedge, can you produce a square of equal area to a given circle?
Surprisingly, mathematicians are still working on this question. And they’re making headway. A paper posted online last week by Andras Máthé and Oleg Pikhurko of the University of Warwick and Jonathan Noel of the University of Victoria is the latest to join in this ancient tradition.

Researchers in Australia have found evidence that bacteria that live in the nose can make their way into the brain through nasal cavity nerves, setting off a series of events that could lead to Alzheimer’s disease. The work adds to the growing body of evidence that Alzheimer’s may be initially triggered through viral or bacterial infections.
“Our work has previously shown that several different species of bacteria can rapidly, within 24 hours, enter the central nervous system via peripheral nerves extending between the nasal cavity and the brain,” said Jenny Ekberg, lead author of the study.
