Plumes of water appear emanating from Europa

Strong evidence here that a sub-surface ocean does exist on the moon but it'll take until at least 2018 and the launch of the James Webb space telescope to further confirm.
New evidence revealed by NASA today suggests Europa might offer us a helping hand when it comes to studying its presumed subsurface ocean, by ejecting water plumes out into space and spraying its surface with more easily sampled material in the process.​

NASA to hold press conference related to Jovian moon Europa

My guess is evidence for subsurface ocean. Tune in 1800 GMT Monday to find out.
There's something going on beneath the surface of Jupiter's icy moon Europa. But what?

1TB SD card prototype shown

SanDisk Western Digital's Extreme Pro SDXC UHS-1 1TB card has been shown at the Photokina 2016 photography trade show. This doubles the 512GB capacity cards they were showing off at the show two years ago.

It is amazing to somebody who remembers megabyte hard drives to think of a terabyte on a postage stamp sized device.

Fun technical note the SDXC (Secure Digital eXtended Capacity) format was announced only in 2009 and allows for capacities up to 2TB. Which means this particular standard is going to run out of steam in a couple of years.

By comparison the Compact Flash 5.0 spec supports up to 128-petabytes (48-bit LBA).

Newest Tesla Model S reaches 100kWh battery

0-60 in 2.5 seconds. 500 kilometer range.

Electric rules, oil drools.

Admittedly a 2.5s high tech luxury sedan isn't cheap but to put it in context this practical seven seater is faster than a McLaren F1 or a Lamborghini Aventador SV and it is still cheaper than a comparable BMW or Mercedes at about $135k USD base price.
With a number of new upgrades announced today, Tesla's Model S is now the third-fastest car in the world, going from 0 to 60 MPH in just 2.5 seconds. That's only just slower than the Ferrari...

No I don't have stock in Tesla. I don't even have a Tesla. But I have read up on how it all works.

And your understanding of power efficiency and usage in vehicles is poor. I will stop the discussion here.

PCI Express 4.0

PCI Express 3.0 slots are pretty quick with almost 1GB/second of bidirectional bandwidth per line. But today's solid state storage systems are become so insanely fast NVMe SSDs are already saturating x4 slots.

GPUs are similarly demanding more communication bandwidth with the rest of the system as they are increasingly used to offload other compute tasks. And it's this bottleneck that drove AMD to bring us a pro-level GPU with 1TB of SSD on the PCI card.

Enter PCI Express 4.0 which we expect finalized by the end of this year.

The big new features are double the bandwidth of PCIe 3.0 to 1.9GB/s bidirectional bandwidth and a big jump from 75 -> 300 watts of power delivery through the slot. Removing the need for additional power connectors for most GPUs. On the other side of the scale there are low power states useful for battery powered devices.

UPDATE: "Unfortunately, a spokesperson for the PCI Special Interest Group (PCI-SIG) incorrectly stated to Tom's Hardware that slot power limits would be raised in the PCIe 4.0 standard. This is not the case: PCIe 4.0 will still have a 75 watt limit on slot power, the same as previous iterations of the spec.
The increased power limit instead refers to the total power draw of expansion cards. PCIe 3.0 cards were limited to a total power draw of 300 watts (75 watts from the motherboard slot, and 225 watts from external PCIe power cables). The PCIe 4.0 specification will raise this limit above 300 watts, allowing expansion cards to draw more than 225 watts from external cables."


Expect to see motherboards and products (like Mellanox's ConnectX-5 100Gb/s) next year - second half of next year probably.,32525.html
PCIe 4.0 will arrive in 2017 with double the bandwidth, but it will also boost the amount of power provided at the slot up to a minimum of 300W, which might eliminate the need for auxiliary power cables with some GPUs.

+Amer oOo Sadly it seems that was an error and the power delivery per slot is not changing (see update).

Four-wheel drive, 3,000 HP, and new world record for VBB-3

It wasn't without challenges but Ohio State University's twin motor electric streamliner just set a new land-speed record in the electric vehicle class.

- Two-way average speed of 341.4 mph / 549.43 kph
- Top speed 358 mph / 576 km/h
- Eight battery packs from A123 Systems
- Most powerful electric car in the world

In perfect conditions the VBB-3 could theoretically break 400mph which the the team's ultimate goal.
With two 1,500-horsepower electric motors, the Venturi Buckeye Bullet can fly on the salt flats.

The universe is still (probably) directionless

Maps of the intensity and polarization of the cosmic microwave background (CMB) radiation show the universe does not appear to be expanding at different rates for different directions. It also does not appear to be rotating.

The universe then is likely not stretching, spinning, rotating, or elongated. It is directionless.

This is what we had assumed so confirming this to a reasonable degree means, for now, cosmology doesn't get a shakeup.
The universe is not spinning or stretched in any particular direction, according to the most stringent test yet.

So, lets step back again to the basics. DNA does not contain a description of the structure of any of the entities it is associated with. DNA is a self catalyzed recipe for seeding the development and metabolic functioning of a biological entity. It knows absolutely nothing about the entity it is building, or by which its metabolic chemical and molecular functions the proteans and enzymes that are patterned off of it. It triggers cascades. Those triggered cascades trigger other cascades patterned in the DNA strand. That is it. Your DNA knows no more about your structure or what you are and are not, than page 335 in a Betty Crocker book knows about the structure of the chocolate cake it instructed you in steps to bake. Much less actually. At least the Betty Crocker recipe tells you it is a chocholate cake, tess you by where the recipe sits, is a dessert. A better analagy to DNA would be one of those Rube Goldberg contraptions you set into motion by rolling a ping pong ball down a ramp, that hits a switch, that releases a weight, that unwraps a spindle, that swings an arm, that tosses some sugar into a pot that tips a scale, that... etc. and results eventually in a chocolate cake.

If you sent someone into the garage that houses that contraption, it would be impossible to extract from that machine the information you'd need to reconstruct a cake once it had been eaten or dropped off a cliff into a volcano or left out in the rain for a week.

Turns out that it is easier to build a self triggered recipe than it is to build a full description of the structure of something. Turns out it is less costly to let self catalyzed recipes make endless copies of entities they know nothing about than it is to keep any one of those entities integral as entropy has its sleepy but constant way.

If you did want to keep something's structure static over time, you'd have to know exactly what that structure was, you'd need a perfect description, you'd then need another perfect description of the first perfect description as the descriptions are just as subject to entropy as the system they describe. Oh and you'd need an endless and ever larger description of the nested descriptions beneath it, and by godel's various proofs, these systems would each be exponentially larger than the sum of the nested descriptions they describe. And you would need a mechanism by which to constantly and unrelentingly scan each nested system for deltas, for errors, and you'd have to break yet more Godel and Turing and Shannon laws by having the capacity to determine which system was the correct system and which was the system containing the error. And then you'd need another system, this one breaking every known law of causality and the second law itself, in order to reach into the primary system, or any of the reference systems, and correcting the error, without by doing so, introducing yet more errors. And, and this is even larger mess, because systems must adjust to changes around and in them, and because a system that can't learn from its environment will be eaten by systems that can, your impossible detect and repair system will need to know how to know the difference between a "good" change and all other "bad" changes. A project that itself demands the very changes that can't be determined good or bad in real time, that exist only for the purpose of determining, by pure brute force, by extreme waste, by absolute indirection, the criteria by which "good" changes might be selected and "bad" changes rejected. All of which adds to the sum of change that determines the rate of entropic production. For instance, the dendtrict structures built in a brain as it responds sensory information and to its own present structure, could not posible be stored in a reference set as they are constantly and must constantly change in order for learning or thinking to happen. A brain that is subject to repair is a brain that can't learn, can't think.

Your DNA knows how to repair you the way soap teaches water how to tell the difference between one molecule and another, not what those molecules are, not where they are, not what they are a part of , just how to break them apart.. So, if you are happy with the way tears in your DNA are reattached by a machine that has no clue what it is repairing, what should and should not be repaired, or why, then you define repair in exactly the way that it already happens, a repair process that results in certain decay and certain death in less than 130 years, most of which, 112 years of which, result in you becoming ever more decrepit, disordered, and dissipated.

But ultimately this discussion does not have much at all to do with the causal limits that make longevity impossible. This discussion, unfortunately, is about or at least exemplifies the struggle that depressed people have with the acceptance of reality, with the many escapist distractions depressed traumatized people construct in order not to have to remember the trauma that has resulted in the depression they need so to survive.

In times past, traumatized people resorted to fantastic religious rapture delusions for the escape distraction they needed. Today, more and more people have supplanted those mystical delusions with fantastic technological rapture delusions. And, just as the desperately religious are so easily identified by their fundamentalist hysteria that is triggered when any of their delusions are questioned, or illuminated, the transhumanist, singularian, space cult, new tech rapturists come absolutely unglued when their desperation fueled distraction schemes are exposed for what they are.

I am sorry to have to say this, because I of course want no further harm to befall you, but you are the quintessential poster boy for the new tech rapture escape and the deep paranoia that fuels it.

There would be no reason for a person not driven by stuffed trauma to say anything at all about any of this, except for the fact that the new tech rapture, in trying so hard to make alchemy of science, to make their existential escape fanaticism seem rational, have cause and continue to cause real damage to what the public knows of science. No one ever confused Zeus's lightning bolt with science, or Moses's magic staff with science, but the general public doesn't usually have the intellectual tools or confidence to determine the difference between the ephemera of science the rockets, test tubes, lab coats, slide rules, computers, and microscopes, and the essence of science, which ironically, is actually the purposeful filtering away of the noise of self such that what is may be known as separate from what we want and fear.

A scientist doesn't do science to live longer, or to get a space ship, or to make their bald spot fill in, or to live longer, or to fly faster, or to get rich, or to win friends, or to influence people... a scientist only does science to figure out the difference between what they want to be true and what actually is true.

Scientists build predictions. Science pretenders build projections. A prediction is true inclusive. A projection is self-centered and only ultimately "predicts" an individual's own fears.

Winner: Close, but Chevy Bolt

Charge speed
Bolt: 25 miles per 1 hour @240v or 90 miles in ~30 minutes with DC fast charge
Model 3: No idea. The Model S and a Supercharger gives you 170 miles in ~30 mins so they may have a head start
Winner: We don't know yet

Bolt: 0-60 in 7 seconds
Model 3: 0-60 in 6 seconds

The dangers of dust at 20% of c

The Breakthrough Starshot project aims to send small craft to the Alpha Centauri star system within our lifetime. Exciting idea indeed: terajoule ground lasers fire into solar sails accelerating small craft to 15-20% the speed of light allowing them to cruise to our nearest star in a mere 30 years or so.

The only problem is at significant percentages of lightspeed collisions with even single atoms can have a measurable effect. Hitting a 15 micron dust molecule could even be fatal for the craft.

"Overall, the authors find the effect of gas to be minor and only likely to cause damage down to a depth of 0.1 millimeters. Dust, however, is a different story. It will evaporate about 1.5 millimeters off the surface of the spacecraft, and melting will happen at depths of up to 10 millimeters. When every gram counts, this could be significant."

Three ways to solve for the problem;
1. Shielding.
2. Low cross section so you hit less stuff.
3. Have a bunch of ships so you can afford to lose a few.
Breakthrough Starshot has examined the impact of stray atoms, cosmic dust.

It is rocket science

NASA's new rocket - the SLS - have been successfully test fired. These are the rockets that will be supporting the Orion spacecraft which could theoretically take humans to the asteroids and to Mars.

"twin boosters - which are 17 stories high EACH - will burn 5 tonnes of propellant per second to create 3.6 million pounds (1.6 million kg) of thrust to kick-start the mission."

"The SLS itself will be taller than the Statue of Liberty, and capable of carrying more than twice the payload weight of any of NASA'S former space shuttles. It's designed to carry four astronauts at a time on board NASA's Orion spacecraft, which had its first test-flight back in December 2014."
NASA has successfully tested the engine that will power its new, massive Space Launch System (SLS) deep-space rocket, reporting no issues across the 7.5-minute duration.

Provided fuel supply was not an issue, how long could an engine like this burn continuously?

Wooden windows

Bleaching wood of its lignin and hardening in epoxy makes for a transparent wood based material that could be used to replace traditional glass windows.

The engineers claim it lets in almost all of the visible light but blocks most of the heat, saving on cooling costs. The other upside is highly diffuse light which comes from the wood's original cell structure which is retained.

The process has been patented and I hope it is cost effective.
Engineers at the A. James Clark School of Engineering at the University of Maryland (UMD) demonstrate in a new study that windows made of transparent wood could provide more even and consistent natural lighting and better energy efficiency than glass.

""pretty simple process" "boiling bath filled with water, sodium hydroxide and other chemicals" Papermaking; don't use a glass container - it dissolves. "soaked the wood with an epoxy" Vacuum impregnate or air bubbles eat you. Did they dehydrate it first? Did they lyophilize the wood to keep it porous? "the end product looks more like a piece of plastic" What weight percent is the epoxy, that being plastic? You can do it with compressed white chicken feather barbs, too, and no lignin. So? Start by growing trees with ester lignins that trivially saponify and wash out, doi:10.1038/nature.2014.14992

doi: 10.1007/s10924-007-0054-7 "the density [of] chicken feathers is about 0.8 g/cm^3 compared to about 1.5 g/cm^3 for cellulose fibers
and about 1.3 g/cm^3 for wool"

Bisphenol-A diglycidyl ether epoxy resins cleave in sunlight at both aromatic ether linkages. Other epoxy resins will drain your wallet. Isocyanate resins also have sunlight issues re Gorilla Glue turning yellow. "Wood Beats Glass" Lizard eats Spock."
