3D House!

A $4K house, 3D-printed in 24 hours

Nonprofit New Story teamed up with construction firm ICON to develop a 3D printer that can construct a four-room house in 12 to 24 hours. Human-built equivalent houses take between 13 to 20 days to build, making this tech a potential game changer for the 1.2 billion people who lack adequate shelter. The team plans to bring costs down from $10,000 to $4,000 per house and build 100 homes in El Salvador next year.

Chinese clone primates (New Barrier Crossed: Humans are in primate family!)




New ethical questions

The birth of these clones also brings up ethical issues. Humans are in the primate family. With this birth, these scientists have broken a barrier and that means the technique could, in theory, be applied to humans. The authors of the paper say they have no intention of trying and they believe their results should spark a wider discussion about the laws and regulations the world needs to regulate cloning.

Drones Starting to Deliver Packages (in Iceland)


At last, a fully operational urban delivery drone system is here... only you probably won't get to use it. Drone logistics startup Flytrex has teamed up with Iceland's main online retailer, AHA, to launch a courier drone service in Reykjavik. Specifically, it's serving one part of Reykjavik -- robotic fliers carry food across a river in the city, cutting the delivery time from 25 minutes to 4.

Amazon Alexa - Be careful what you say... :)

Dallas, Tx. resident Megan Neitzel, recently received the Echo Dot as a holiday gift from her in-laws. However, Neitzel was surprised when she received a confirmation email for cookies and a dollhouse that had been ordered.

According to Neitzel, the device had not been hooked up for long, and while she overheard her kids telling Alexa Knock-Knock jokes, the cost of the items on the invoice was no laughing matter.

"It was a $170 Kidcraft dollhouse and 64 ounces, four pounds, of cookies," she told Foxnews.com.

...

Given that this is their first experience with Alexa, Neitzel said they are a bit more cautious with what they say around it. "I [feel] like whispering in the kitchen," she said. "I tell my kids Alexa is a very good listener."

Dinosaur Tail Preserved in Amber (Check out the feathers!)



The tail of a feathered dinosaur has been found perfectly preserved in amber from Myanmar.

The one-of-a-kind discovery helps put flesh on the bones of these extinct creatures, opening a new window on the biology of a group that dominated Earth for more than 160 million years.

Examination of the specimen suggests the tail was chestnut brown on top and white on its underside.

The tail is described in the journal Current Biology.

"This is the first time we've found dinosaur material preserved in amber," co-author Ryan McKellar, of the Royal Saskatchewan Museum in Canada, told the BBC News website.

Life on Mars?!!

CNN reports:  

Life could exist in isolated pockets beneath the surface of Mars, according to Alfred McEwen, principal investigator of NASA's HiRISE high-resolution camera aboard the Mars Reconnaissance Orbiter. While they would most likely be primitive microorganisms such as bacteria, it would still be proof of life outside of our own planet.

Clearing Space on your Gmail acct

Google limits the space you have on Gmail and Google drive (or Gdrive) to 15 GB.  If you are bumping up against that limit, here are some tricks to use:

My favorite is clearing out large files (which are often digital photos you already have somewhere else if you want them).

Search by size

Once upon a time you couldn't search for emails by size in Gmail, but now you most certainly can. Enter larger:5m to find messages of 5MB or above, or open up the search drop-down dialog and use the size option there.
In my own creaking Gmail account I found 356 emails that were 5MB or bigger, which works out at at least 1.78GB of room that can be cleared. If you regularly use your Gmail account to handle high-resolution photos or PDFs then you might come across more matching messages than you expect.

Asteroid Passes Near Earth -- with it's own Moon!

On Monday, January 26th, an asteroid passed by the earth at about 3x the distance between the moon and the earth.  The asteroid is about a third of a mile in size.

Interestingly, the asteroid had its own moon (about 240 feet in diameter) circling it.

The asteroid was named 2004 BL86, because it was first spotted back in 2004 (by an observatory in New Mexico).

CNN Reports:

It was far enough that it didn't pose a threat to Earth, but close enough to give scientists and amateurs a chance to observe a large asteroid up close.NASA asteroid 2004 BL86 was revealed to have its own small moon.NASA asteroid 2004 BL86 was revealed to have its own small moon.
EXPAND IMAGE
It was the closest known asteroid this large to pass near Earth until 2027, when an asteroid called 1999 AN10 flies by.

Self-Driving Cars Coming in a few years!

Some of you may have heard of the Google self-driving car...  GM is making advances in this area -- and the firm says that some of these features will be on the road in just two+ years!  Read more here:


Cars that can talk to each other and almost drive themselves at freeway speeds are just two years away from the showroom, General Motors executives indicate.

The carmaker announced Sunday that the semiautonomous system for freeways will be an option on an unidentified 2017 Cadillac that goes on sale in summer 2016. Another 2017 Cadillac, the CTS, will be equipped with radio transmitters and receivers that will let it communicate with other cars, sharing data such as location, speed, and whether the driver is applying the brakes.

Hawkings: AI Could Be Dangerous

With the Johnny Depp movie making noise at the box office, Stephen Hawkings spoke out about the dangers that artificial intelligence can pose to mankind.



With the Hollywood blockbuster Transcendence playing in cinemas, with Johnny Depp and Morgan Freeman showcasing clashing visions for the future of humanity, it's tempting to dismiss the notion of highly intelligent machines as mere science fiction. But this would be a mistake, and potentially our worst mistake in history.

The Earth's Core is as Hot as the Sun's Surface

This may be hard to believe but it is true.  This fact is helped because the surface of the sun is surprisingly cool.  Weirdly enough both the Earth's core and sun's surface are about 6,000 degrees Kelvin -- but the sun's atmosphere (also called the corona) is 1 to 2 million degrees Kelvin!

A new study in Science suggests that the temperature of our planet's core is much, much hotter than previously thought -- 6,000 degrees Kelvin, compared with earlier estimations that were closer to 5,000 degrees Kelvin. This temperature, blazing hot to a degree beyond comprehension, is the same as that of the surface of the sun. Yes, you read that right: the core of our temperate little atmospherically-protected home is as hot as *a star*.

Scientists in France were able to come to their remarkable conclusion in an experimental setting, using X-rays diffraction to watch how iron crystals held under unbelievable pressure form and melt.

Earthquakes and Tsunamis: Quake hits Los Angeles 3/17/14

On Monday, March 17, 2014 - St. Patrick's Day -- there was an earthquake in Los Angeles.  Although the quake was measured at a 4.4-magnitude earthquake on the Richter scale, you can clearly see the impact on people during an earthquake.

There were at least six aftershocks, with the strongest being measured at a 2.7-magnitude temblor. Some fear that this quake could mark the end of the several year "earthquake drought" that the area has experienced.  Below is a video of newscasters live when the earthquake hit.




The earthquake also made us recall the 2011 Japanese earthquake and Tsunami. All of Japan moved about 10 feet!

Large Asteroid Passes near Earth

An asteroid as wide as two football fields passed relatively close to Earth.  The nearest it came to our planet was roughly eight times the distance from the earth to the moon (the Earth-moon distance averages 239,000 miles) -- so the asteroid passed about 2 million miles from the Earth!

Solar System Theory

Here is a nice lecture from Arizona State University on the Nebula Theory of the creation of the solar system.


III. Formation of the planets

  • The first solid particles were microscopic in size. They orbited the Sun in nearly circular orbits right next to each other, as the gas from which they condensed. Gently collisions allowed the flakes to stick together and make larger particles which, in turn, attracted more solid particles. This process is called accretion.
  • The objects formed by accretion are called planetesimals (small planets): they act as seeds for planet formation. At first, planetesimals were closely packed. They coalesced into larger objects, forming clumps of up to a few kilometers across in a few million years, a small time compared to the age of the solar system (movie).
  • Once planetesimals had grown to these sizes, collisions became destructive, making further growth more difficult (movie). Only the biggest planetesimals survived this fragmentation process and continued to slowly grow into protoplanets by accretion of planetesimals of similar composition.

Amazon testing Drones for Delivery!

Wow: science is advancing at increasingly fast rates!  Check out what Amazon is testing and thinking about...




Amazon says it will take years to advance

Photo credit: AP


Amazon's plan to eventually enlist self-guided drones to deliver packages to customers in 30 minutes or less, revealed Sunday night on CBS' "60 Minutes," opens a host of possibilities -- and hazards.
Amazon.com Inc. says it's working on the so-called Prime Air unmanned aircraft project in its research and development labs. The company admits it will take years to advance the technology and for the Federal Aviation Administration to create the necessary rules and regulations.
Amazon CEO Jeff Bezos said in the prime-time interview that while his octocopters look like something out of science fiction, there's no reason they can't be used as delivery vehicles.
Bezos said the drones can carry packages that weigh up to five pounds, which covers about 86 percent of the items Amazon delivers. The drones the company is testing have a range of about 10 miles, which Bezos noted could cover a significant portion of the population in urban areas.
Bezos told "60 Minutes" the project could become a working service in four or five years.
