Antidepressants May be Worsening Depression, Not Treating It

Julie Fidler, Natural SocietyCould it all be based on a myth?For years we’ve been told that depression is caused by low serotonin levels in the brain.Now, a leading professor of psychiatry is warning that belief is little more than a dangerous miscommunication, saying the marketing of selective serotonin reuptake inhibitor (SSRI) drugs is “based on a myth.”SSRI use began to skyrocket in the early 1990’s. The drugs were seen as a safer alternative to [...]

NASA Challenges People to Come Up With Designs for Mars Habitat –





Excerpt from perfscience.com

The space agency NASA has asked public to submit designs for a Mars habitat. NASA, along with the National Additive Manufacturing Innovation Institute, is holding a competition to design and build a 3-D printed habitat for deep space explorations like journey to Mars.  The multi-phase 3-D Printed Habitat Challenge has been specifically designed to advance the additive construction technology that is needed to develop sustainable housing solutions for earth and beyond.  As per experts, shelter is among most basic and crucial requirement for humans but carrying bulks of material to build up a habitat during a deep space mission would unnecessarily take the place in cargo that could be used for something important.  The first phase of the competition that was announced on Saturday will run through September 27. This phase calls on participants to develop state-of-the-art architectural concepts that take advantage of the unique capabilities 3-D printing offers.  The top 30 submissions will be considered and judged. Also winners will be awarded with prize money of $50,000 at the 2015 World Maker Faire in New York.  Sam Ortega, Centennial Challenges program manager, said, “This challenge definitely raises the bar from what we are currently capable of, and we are excited to see what the maker community does with it”...

Sam Ortega, Centennial Challenges program manager, said, “This challenge definitely raises the bar from what we are currently capable of, and we are excited to see what the maker community does with it”.
Furthermore the second phase of the competition is divided into two levels i.e., the (Level 1) Structural Member Competition and the On-Site Habitat Competition (Level 2).
The Level 1 focuses on the fabrication technologies that are needed to manufacture structural components from a combination of indigenous materials and recyclables, or indigenous materials alone.
On the other hand, the Level 2 challenges competitors to construct full-scale habitats using indigenous materials or indigenous materials combined with recyclables.

Here’s Why Tesla’s Battery Is A Big Deal


Excerpt from forbes.com

It’s more about where the market and product are going than where they are today. Think about a complementary system of components:

  1. The big grid – always on, highly reliable power which is expensive during peak demand hours, i.e. when a family actually wants to use the power. But usually the electricity is cheap at night when no one wants to use it and those big baseload plants that are hard (or very hard in the case of nuclear) to slow down are still pumping out power. And sometimes that power is provided by strong night winds.
  2. Home solar – Don’t forget that Tesla’s CEO, Musk, is also Chairman of SolarCity which provides zero down leasing. Home solar is often poorly aligned to peak usage, with installers looking for maximum generation with south-facing solar panels rather than maximum generation during peak with south-west facing panels. Then there are the homes with roofs that are poorly aligned to the sun regardless, so imperfect generation is all that is possible. And that peak generation isn’t necessarily perfectly aligned with peak cost of grid electricity either, but merely overlaps with it.
  3. Home storage – Maximum generation alignment of home solar matters less when you can carry forward the unconsumed electricity from solar panels to your evening of cooking, washing dishes, washing clothes, and streaming Netflix on your 40″ tv. And cheap electricity you can store at night and consume when electricity is really expensive is valuable as well.
So these components exist, but to be fair, they existed before Tesla got into the home storage business and have for a long time. And Tesla’s offering costs about twice as much as more typical lead-acid batteries commonly used for the purpose. So why is this particular home storage battery getting so much attention?
  1. Hype – Don’t underestimate the marvel that is Musk’s ability to get attention. The man is a rock star of event unveiling.
  2. Net metering – Right now, there is a lot of conflict between utilities and home solar users and installation companies. Net metering is the requirement that home solar generators get paid for electricity that they produce and pump into the grid, and only pay for the electricity that they draw from the grid. Output vs input is the net. Home solar used to be an advantage to utilities — reduced peak demand — but has become a liability — reduced or even negative revenue from users of the grid. Basically, utilities still have to pay for the grid which home solar generators use, then they lose revenue or outright pay the home solar generator who is getting use of the grid for free. Since utilities pay for the grid out of electricity revenue, they are starting to demand that people with home solar who aren’t paying much for electricity start paying for grid usage to make up for it. This is getting mixed reviews, as you can understand, but in the USA especially is leading to a desire by many to be completely grid free, a dubious value proposition. Tesla’s hype fell into an emerging market opportunity of people who had solar on their roof, didn’t have batteries but are worried that they’ll be forced to pay more.
  3. Time-of-use billing – Combined with smart meters, time-of-use billing is becoming much more common in utilities in the developed world. This model is simple: reduce demand during peak periods by increasing the price, typically combined with incenting shift of demand to off-peak times by lowering the price. Flattening demand curves, especially peaks, is very advantageous for grid managers because they have to have capacity for the peak. This enables storage to time-shift consumption and save at least some money.
  4. Design – Previous storage units are collections of lead acid batteries, basically the same thing you have in your car, but scaled vertically and horizontally. They aren’t pretty, they are heavy, they take up floor space, they require maintenance, and they are pretty much a toxic addition to homes if breached or even if the tops are removed. Tesla’s model is sleek, hangs on a wall and is much more chemically inert with no liquids. It’s a benign home appliance as opposed to an industrial object (much as some people like the industrial aesthetic at home, it’s less common).
  5. The Gigafactory – What Tesla has going for it is that it is building the world’s largest battery factory, and likely expanding it now that the storage line has taken off so brilliantly. Pretty much everyone paying attention knows that Tesla is already producing batteries much more cheaply on a per KWH capacity at greater volume, and the Gigafactory is going to ramp that up. Battery storage has been dropping in price per KWH of capacity for a long time, but it’s closing in on a cusp point where it’s going to be worth it for average consumers to store at least some electricity.
What all of this adds up to is that home battery storage isn’t economical today, but it’s viable for a subset of the high-consuming market, it’s desirable for its green credentials, it’s desirable due to the hype factor and it will defray its costs. And that the home storage market tomorrow will be viable for a much larger percentage of the market with increasing systemic pressures and pricing that will make it more attractive. Tesla’s home storage battery is getting attention because they are staking a major claim to a market which is expected to increase dramatically.

Rare Quartet of Quasars Found in the Early Universe


This image shows a rare view of four quasars, indicated by white arrows, found together by astronomers using the Keck Observatory in Hawaii. The bright galactic nuclei are embedded in a giant nebula of cool, dense gas visible in the image as a blue haze. Hennawi & Arrigoni-Battaia, MPIA


Excerpt from smithsonian.com

The odds of success would make a Vegas bookie sit up and take notice. But in a one-in-10 million chance, astronomers surveying the sky have found a group of four tightly packed quasars in one of the most distant parts of the universe. The rare grouping may be a nascent galaxy cluster, and its unusually cold cradle of gas could prompt a re-think of how we model the early universe.

Quasars are among the brightest objects known—according to NASA, each one gives off more energy than 100 mature galaxies combined. But quasars are found only in the far reaches of the universe and can't be seen with the naked eye. Because of the time it takes light to travel that far, detecting such distant objects is akin to seeing back in time, so astronomers think quasars are the seeds of young galaxies, powered by gases falling into the supermassive black holes at their cores. As matter falls inward and gets close to the speed of light, it emits radiation that we can pick up with telescopes.

The quasar phase doesn't last long, only about a thousandth of a galaxy's lifetime. After that, the brightness dies down as the inflow of matter slows, says study leader Joseph Hennawi, an astrophysicist at the Max Planck Institute in Germany. Seeing any two quasars close together while they are still bright is a chancy business, so his team wasn't sure what they'd find when they set out to survey quasars using the W.M. Keck Observatory in Hawaii. To their surprise, they quickly pinpointed four of them in close proximity, cosmically speaking. The quartet is huddled up in an area of sky less than 600,000 light-years across that sits about 10 billion light-years from Earth.

"The authors found it by investigating the environment of just 29 bright quasars," says Michele Trenti, a senior lecturer at the University of Melbourne's School of Physics. "So at face value it seems like winning the lottery with a handful of tickets."
That's not all that was strange about this quasar quartet. The foursome was found inside a cloud of cold, dark gas, and the team's observations suggest that similar clouds surround about 10 percent of the tens of thousands of known quasars. That's odd, because according to current theories, quasars in groups like this should be surrounded by hot plasma, or ionized gas, at a temperature of about 10 million degrees.

“What this means is that there is some physical process that the models aren’t capturing,” says Hennawi, whose team reports the discovery this week in Science.
