Poker Professional Maria Konnikova
Professional poker player Maria Konnikova explains how she exploits irrational prejudices by male poker players to her advantage:
FWIW, she has won $200,000 over the past year of playing professionally.There are people who’d rather die than be bluffed by a woman. They’ll never fold to me because that’s an affront to their masculinity.I never bluff them. I know that no matter how strong my hand, they are still going to call me because they just can’t fold to a girl.
Other people think women are incapable of bluffing. They think if I’m betting really aggressively, it means I have an incredibly strong hand. I bluff those people all the time.
Parker Solar Probe
"As strange as it may sound, it's much more difficult to reach the sun than it is to leave the solar system altogether":
“I’m always amused when someone says, ‘Shoot X or so-and-so into the sun,’” says Rand Simberg, a space consultant and an engineer. “Because they have no idea how hard that is to do.”
The reason has to do with orbital mechanics, the study of how natural forces influence the motions of rockets, satellites, and other space-bound technology. Falling into the sun might seem effortless since the star’s gravity is always tugging at everything in the solar system, including Earth. But Earth—along with all the other planets and their moons—is also orbiting the sun at great speed, which prevents it from succumbing to the sun’s pull.
This arrangement is great if you’d like to avoid falling into the sun yourself, but it’s rather inconvenient if you want to launch something there.

Laundering Money With In-Game Purchases

Battery Progress
"The next major innovation in batteries might be here":
Pellion’s battery can pack nearly double the energy of a conventional lithium-ion battery, making it able to, for example, double the time a drone can spend in the air. That 100% increase in energy density is a step change compared to the annual 10% or so improvement the battery industry currently averages.

Reading Ancient Texts
"Buried by the Ash of Vesuvius, These Scrolls Are Being Read for the First Time in Millennia":
The scrolls represent the only intact library known from the classical world, an unprecedented cache of ancient knowledge. Most classical texts we know today were copied, and were therefore filtered and distorted, by scribes over centuries, but these works came straight from the hands of the Greek and Roman scholars themselves. Yet the tremendous volcanic heat and gases spewed by Vesuvius carbonized the scrolls, turning them black and hard like lumps of coal. Over the years, various attempts to open some of them created a mess of fragile flakes that yielded only brief snippets of text. Hundreds of the papyri were therefore left unopened, with no realistic prospect that their contents would ever be revealed. And it probably would have remained that way except for an American computer scientist named Brent Seales, director of the Center for Visualization & Virtual Environments at the University of Kentucky...

Insecure Voting
"Top Voting Machine Vendor Admits It Installed Remote-Access Software on Systems Sold to States":
In a letter sent to Sen. Ron Wyden (D-OR) in April and obtained recently by Motherboard, Election Systems and Software acknowledged that it had "provided pcAnywhere remote connection software … to a small number of customers between 2000 and 2006," which was installed on the election-management system ES&S sold them.
The statement contradicts what the company told me and fact checkers for a story I wrote for the New York Times in February. At that time, a spokesperson said ES&S had never installed pcAnywhere on any election system it sold. "None of the employees, … including long-tenured employees, has any knowledge that our voting systems have ever been sold with remote-access software," the spokesperson said.
Genomes To Face
"Researchers produce images of people's faces from their genomes":
Creating pictures of people’s faces from their genomes has a number of potential uses, especially in forensic science. It might be possible to reconstruct the face of a perpetrator from any genetic material they have left behind, such as blood or body fluids. That would allow police to “see” the face of suspects in cases of murder, assault and rape. It could also help with identifying unrecognisable victims who have been burned or maimed. Unsolved cases might be reopened if suitable samples were still available.
As Dr Venter is quick to point out, this technology has other implications, among them for privacy. He considers that genomic information must now be treated as personal information, even if it is presented as an anonymised sequence of letters—as is currently the case in some countries...

Blazar Update
"The IceCube Neutrino Detector at the South Pole Hits Paydirt":
...And these led to the first ever identification of the birthplace of a neutrino from outside our galaxy: in this case, the unimaginably violent cosmic forge of a blazar.
Blazars are incredibly bright natural sources of radio waves. They form when some of the swirling material falling into a supermassive black hole is converted into a hot radiating soup of elementary particles and then gets blasted back out into space in the form of twin jets moving at close to the speed of light.

IEEE Statement On Strong Encryption
"IEEE Statement on Strong Encryption vs. Backdoors"
IEEE supports the use of unfettered strong encryption to protect confidentiality and integrity of data and communications. We oppose efforts by governments to restrict the use of strong encryption and/or to mandate exceptional access mechanisms such as "backdoors" or "key escrow schemes" in order to facilitate government access to encrypted data. Governments have legitimate law enforcement and national security interests. IEEE believes that mandating the intentional creation of backdoors or escrow schemes -- no matter how well intentioned -- does not serve those interests well and will lead to the creation of vulnerabilities that would result in unforeseen effects as well as some predictable negative consequencesYou can read their full statement here.

Chaotic Clouds of Jupiter
NASA: "Chaotic Clouds of Jupiter":
NASA’s Juno spacecraft took this color-enhanced image at 10:23 p.m. PDT on May 23, 2018 (1:23 a.m. EDT on May 24), as the spacecraft performed its 13th close flyby of Jupiter. At the time, Juno was about 9,600 miles (15,500 kilometers) from the planet's cloud tops, above a northern latitude of 56 degrees.
The region seen here is somewhat chaotic and turbulent, given the various swirling cloud formations. In general, the darker cloud material is deeper in Jupiter’s atmosphere, while bright cloud material is high. The bright clouds are most likely ammonia or ammonia and water, mixed with a sprinkling of unknown chemical ingredients.
A bright oval at bottom center stands out in the scene. This feature appears uniformly white in ground-based telescope observations. However, with JunoCam we can observe the fine-scale structure within this weather system, including additional structures within it...

AI Vs. Dermatologists
"AI detects skin cancers with more accuracy than dermatologists":
“The CNN [convolutional neural network] missed fewer melanomas, meaning it had a higher sensitivity than the dermatologists, and it misdiagnosed fewer benign moles as malignant melanoma, which means it had a higher specificity,” Haenssle said. “This would result in less surgery.”

Magnetically Activated Micromachines
"Magnetically Activated Micromachines to Operate Remotely Inside Body":
Engineers at MIT have created a class of magnetically activated bug-like microdevices that may foreshadow remote-controlled surgical tools and externally powered heart-assist pumps. These interesting devices have an origami-like look and a variety of them have been built that crawl, jump, grasp, and do other things. They’re actually printed from soft materials that have ferromagnetic nanoparticles within their interior, allowing a magnet to manipulate them.
