The Japanese Space Agency's Hyabusa-2 probe is about to touch down on the asteroid 162173 Ryuga.

A live stream of the event will be available here starting at 4:45pm ET

The asteroid-circling spacecraft won't land so much as delicately brush the surface of Ryugu. During the late stages of descent, the probe will fire a tantalum pellet at the asteroid surface. The 650-mile-per-hour collision will create a plume of dust and debris that Hayabusa-2 will attempt to scoop up with an instrument dubbed the Sampler Horn.

This is equivalent to a bit over 6x the speed of the fastest slapshot ever recorded in an Ice Hockey Rink.

This will be the first of three passes to collect rock and dust samples from the asteroid. Samples will be returned to Earth in 2020.

Neuroscientists at Case Western Reserve University claim to have discovered a previously unknown mechanism for neuron communication. Using electric fields, neurons are able to activate other nearby neurons even when there is no physical connection between the cells. In one test, the scientists used a hippocampal slice of a mouse brain, and found that after cutting the slice in half and separating the pieces, they were able to induce a signal in one half which could bridge the gap and generate activity in the other.

AIUI, we've known the brain produces and can be influenced by electric fields for decades, so this doesn't seem particularly surprising, although it's still rather interesting if it helps to truly understand what's going on. Personally, I'm wondering if this will allow a brain-computer interface without drilling through the skull to implant electrodes... :)

Research paper: Slow periodic activity in the longitudinal hippocampal slice can self‐propagate non‐synaptically by a mechanism consistent with ephaptic coupling

On Friday, the EU Commission published a piece on Medium that suggested that Google has taken over the minds of millions of citizens, rendering them incapable of thinking for themselves in their opposition of Article 13. The piece was later deleted with a note implying that people simply aren't capable of understanding the subtle nuances of the English language.

Last week the European Parliament and European Council agreed on the final text of the EU Copyright Directive.

Supporters of Article 13 say this will lead to a better deal for the entertainment industries at the expense of Google's YouTube, since it will have to obtain proper licenses for content uploaded to platform, while taking responsibility for infringing uploads.

Opponents, on the other hand, believe that the Article 13 proposals will be bad news for the Internet as a whole, since they have the potential to stifle free speech and expression, at the very least.

It's important to note that Article 13 opponents come in all shapes and sizes, some more militant than others. However, last Friday the EU Commission took the 'one size fits all approach' by labeling every dissenting voice as being part of a "mob", one groomed, misinformed and misled by Google. [...]>

I'm not sure who in the world [h]as the expectation that lawmakers be clear and unambiguous in all their communications. But even putting that aside, it might be fun to have a quick game of logical fallacy spotting on both sides of this spat. Alas one might start with some anti-EU-commission bias, thinking that they don't understand how the internet works, as they appear to think that you can "delete" things that have appeared on the internet. Aww, how cute! -- Ed.(FP)

CERN has published a javascript implementation of their original web browser. The browser itself, WorldWideWeb, is text only and predates not only graphical browsing but also cookies, the pox javascript, and HTTPS. Their site dedicated to the browser also has a brief history of the application which was built in 1989 as a progenitor to what we know as "the web" today, timeline spanning three decades on either side of its release, instructions for its use, a look at some of the original code of WorldWideWeb, how the WorldWideWeb browser was rebuilt, various historical and technical resources, and who did the work to make this possible. Interestingly some current web sites are apparently standards compliant enough that they function, somewhat, in the old browser.

Hello, World

In December 1990, an application called WorldWideWeb was developed on a NeXT machine at The European Organization for Nuclear Research (known as CERN) just outside of Geneva. This program – WorldWideWeb — is the antecedent of most of what we consider or know of as "the web" today.

In February 2019, in celebration of the thirtieth anniversary of the development of WorldWideWeb, a group of developers and designers convened at CERN to rebuild the original browser within a contemporary browser, allowing users around the world to experience the rather humble origins of this transformative technology.

Arthur T Knackerbracket has found the following story:

President Donald Trump isn't giving up on his vision of creating a new Space Force within the US military, even if it has to start out small.

Speaking at the Brookings Institution Tuesday morning, Air Force Chief of Staff Gen. David Goldfein confirmed reports that Trump will sign Space Policy Directive 4. "That will establish the Space Force... within the Department of the Air Force," Goldfein said.

Initially, the White House had sought to create a Space Force as a brand new branch of the military, equal in standing to the Army, Navy, Air Force, Marine Corps and Coast Guard. But the proposal ran into opposition from both Republicans and Democrats in Congress, which must approve the creation of a new military branch.

With Democrats now in control of the House of Representatives, the White House appears to be pursuing a "plan B" that sets up a sort of miniature Space Force under the Air Force. Notably, the new entity maintains the Space Force name, and the directive that's awaiting the president's signature also keeps the goal of converting it into a full-fledged military branch at some point in the future. 

"I think the fact that we're having a national debate on space is really healthy," Goldfein said. "We're the best in the world in space and our adversaries know it. They've been studying us and they've been investing in ways to take away that capability in crisis or conflict... We as a nation cannot let that happen."

The supposed deleted text:

The Sun is the primary forcing of Earth's climate system. Sunlight warms our world. Sunlight drives atmospheric and oceanic circulation patterns. Sunlight powers the process of photosynthesis that plants need to grow. Sunlight causes convection which carries warmth and water vapor up into the sky where clouds form and bring rain. In short, the Sun drives almost every aspect of our world's climate system and makes possible life as we know it.

Earth's orbit around and orientation toward the Sun change over spans of many thousands of years. In turn, these changing "orbital mechanics" force climate to change because they change where and how much sunlight reaches Earth. (Please see for more details.) Thus, changing Earth's exposure to sunlight forces climate to change. According to scientists' models of Earth's orbit and orientation toward the Sun indicate that our world should be just beginning to enter a new period of cooling — perhaps the next ice age.

However, a new force for change has arisen: humans. After the industrial revolution, humans introduced increasing amounts of greenhouse gases into the atmosphere, and changed the surface of the landscape to an extent great enough to influence climate on local and global scales. By driving up carbon dioxide levels in the atmosphere (by about 30 percent), humans have increased its capacity to trap warmth near the surface.

Other important forcings of Earth's climate system include such "variables" as clouds, airborne particulate matter, and surface brightness. Each of these varying features of Earth's environment has the capacity to exceed the warming influence of greenhouse gases and cause our world to cool. For example, increased cloudiness would give more shade to the surface while reflecting more sunlight back to space. Increased airborne particles (or "aerosols") would scatter and reflect more sunlight back to space, thereby cooling the surface. Major volcanic eruptions (such as that of Mt. Pinatubo in 1992) can inject so much aerosol into the atmosphere that, as it spreads around the globe, it reduces sunlight and cause Earth to cool. Likewise, increasing the surface area of highly reflective surface types, such as ice sheets, reflects greater amounts of sunlight back to space and causes Earth to cool.

Scientists are using NASA satellites to monitor all of the aforementioned forcings of Earth's climate system to better understand how they are changing over time, and how any changes in them affect climate.

Last year the Australian government decided to follow in the ill fated footsteps of other countries and change the electronic online health system from opt out to opt in causing many people to make the effort to out out. When you see millions of Australians getting off of their collective arses for something like this you know it is serious. More serious perhaps than the Sunday football. Then the pollies extended the opt out period a couple of times. To give everyone a chance to vote with their feet. Now that the final final final opt out period has ended the numbers are in.
Around 10 percent of the population of Australia opted out of the ehealth record system. Those who are left will now have a record created for them and data automatically loaded into it from government systems.

I am so shocked. Australians. Doing something. Shocked, I tell you, shocked. And alarmed.

A security consulting firm released a report on the safety of password managers. A non-geek, summarized version is also available at the Washington Post. (Summarized graphic of results.)

The password managers included in the study were 1Password 4, 1Password 7, Dashlane, KeePass, LastPass. Unfortunately, the testing was limited to Win10 even if the password managers were available on other platforms. They all had some flaws, but as reported, you should still use one. They were all tested for encryption method on the database, accessibility of the master password and keys in memory while unlocked, and the master password and keys in memory while locked.

All were evaluated to have adequate encryption on the file. 1Password 4 (which actually had better memory security than 1Password 7,) was best at keeping individual passwords safe in memory; while KeePass was best at keeping the Master Password safe in the memory tests (although Dashlane did the same while it while in a locked state.)

When Kids Realize Their Whole Life Is Already Online

Not all kids react poorly to finding out they’ve been living an unwitting life online. Some are thrilled. In fourth grade, Nate searched his name and discovered that he was mentioned in a news article about his third-grade class making a giant burrito. “I didn’t know,” he said. “I was surprised, really surprised.” But he was pleased with his newfound clout. “It made me feel famous … I got to make new friends by saying, ‘Oh, I’m in a newspaper [online],’” he said. Ever since, he has Googled himself every few months, hoping to find things.

[...] Once kids have that first moment of realization that their lives are public, there’s no going back. Several teens and tweens told me this was the impetus for wanting to get their own social-media profiles, in an effort to take control of their image. But plenty of other kids become overwhelmed and retreat. Ellen said that anytime someone has a phone out around her now, she’s nervous that her photo could be taken and posted somewhere. “Everyone’s always watching, and nothing is ever forgotten. It’s never gone,” she said.

[...] Still, Jane—who, like all the other kids in this story, spoke to me with her parents’ permission—worries. She’s too young to navigate the web on her own, but she feels that a lot of what’s out there on the internet about her is beyond her control. “I don’t really like how people know things about me, and I don’t even know them,” she said. “Thousands and millions of things are out there maybe.” Andy, also 7, is always on the lookout for people who might take unflattering photos of him. He once caught his mother taking a photo of him sleeping and, another time, doing a silly dance. He immediately told her not to post it on Facebook, and she obliged. He felt the photos were embarrassing.

Remember your search engine is watching you when you search for yourself.

Watch the historic first private mission to the Moon launch Thursday night

For the first time later this week, a privately developed moon lander will launch aboard a privately built rocket, organized by a private launch coordinator. It’s an historic moment in space and the Israeli mission stands to make history again if it touches down on the Moon’s surface as planned on April 11.

The Beresheet (“Genesis”) program was originally conceived as an entry into the ambitious but ultimately unsuccessful Google Lunar Xprize in 2010, which challenged people to accomplish a lunar landing, with $30 million in prizes as the incentive. The prize closed last year with no winner, but as these Xprize competitions aim to do, it had already spurred great interest and investment in a private moon mission.

SpaceIL and Israel Aerospace Industries worked together on the mission, which will bring cameras, a magnetometer and a capsule filled with items from the country to, hopefully, a safe rest on the lunar surface.

[...] Russia, China and of course the U.S. are the only ones ever to successfully land on the Moon; China’s Chang’e 4 lander was the first to soft-land (as opposed to impact) the “dark” (though really only far — it’s often light) side and is currently functional.

[...] Seattle’s Spaceflight coordinated the launch, and technically Beresheet is the secondary payload; the primary is the Air Force Research Labs’ S5 experimental satellite, which the launch vehicle will take to geosynchronous orbit after the lunar module detaches.

There is a video on YouTube showing the steps planned to take the craft from Earth orbit to Moon orbit and, hopefully eventually, to the Moon's surface.

You can watch it live-streamed on YouTube starting about 20 minutes before launch:

Supreme Court curbs power of government to impose heavy fines and seize property

In a unanimous decision, the Supreme Court on Wednesday ruled to drastically curb the powers that states and cities have to levy fines and seize property, marking the first time the court has applied the Constitution's ban on excessive fines at the state level.

Justice Ruth Bader Ginsburg, who returned to the court for the first time in almost two months after undergoing surgery for lung cancer, wrote the majority opinion in the case involving an Indiana man who had his Land Rover seized after he was arrested for selling $385 of heroin.

"Protection against excessive fines has been a constant shield throughout Anglo-American history for good reason: Such fines undermine other liberties," Ginsburg wrote. "They can be used, e.g., to retaliate against or chill the speech of political enemies. They can also be employed, not in service of penal purposes, but as a source of revenue."

Machine-learning techniques used by thousands of scientists to analyse data are producing results that are misleading and often completely wrong.

Dr Genevera Allen from Rice University in Houston said that the increased use of such systems was contributing to a "crisis in science".

She warned scientists that if they didn't improve their techniques they would be wasting both time and money. Her research was presented at the American Association for the Advancement of Science in Washington.

A growing amount of scientific research involves using machine learning software to analyse data that has already been collected. This happens across many subject areas ranging from biomedical research to astronomy. The data sets are very large and expensive.

[...] "There is general recognition of a reproducibility crisis in science right now. I would venture to argue that a huge part of that does come from the use of machine learning techniques in science."

The "reproducibility crisis" in science refers to the alarming number of research results that are not repeated when another group of scientists tries the same experiment. It means that the initial results were wrong. One analysis suggested that up to 85% of all biomedical research carried out in the world is wasted effort.

It is a crisis that has been growing for two decades and has come about because experiments are not designed well enough to ensure that the scientists don't fool themselves and see what they want to see in the results.

Crossbar, which has talked up its version of a post-NAND memory/storage technology for years with little to show for it, now has to compete with the elephant in the room:

Crossbar, developer of Resistive RAM (ReRAM) chips, is setting up an AI consortium to help counter, er, resistance to the technology, speed up its adoption, and hopefully outrun Intel's Optane.

ReRAM is a type of non-volatile memory with DRAM-class access latency. So, flash-style solid-state storage with RAM-ish access. However, it is taking a long time to mature into a practical technology that can be deployed in devices to fill the gap between large-capacity, non-volatile, relatively slow NAND, and high-speed, relatively low capacity, volatile DRAM.

[...] Crossbar claims it can design "super dense 3D cross-point arrays, stackable with the capability to scale below 10nm, paving the way for terabytes on a single die." Beat that, Optane. Check out a white paper from the upstart here (registration needed.)

Crossbar continued to develop its ReRAM, inking a licensing agreement with Microsemi in May last year, involving the use of sub-10nm ReRAM tech in coming Microsemi products.

[...] Crossbar says it's working with Japanese authorities to review opportunities for the 2020 Olympics, including video-based event detection and response capability. We'll see if anything comes of that.
