Science!

Some sciency stuff!

    The burial chamber contained the remains of 11 men, women and children, suggesting it was a family cemetery used for generations during the 12th and 13th Dynasty.

    The find marks the first Middle Kingdom tomb that has been discovered in the area
[Luxor], which ranged from 1938 BC to 1630 BC. 

    About two weeks ago, October 16, Voyager 1 put itself into a safe mode after receiving a transmission from its mission control via the Deep Space Network commanding the satellite to turn on one of its heaters.  Because it takes just about a full day for radio transmission to get to the satellite and another full day before the response is known, they found out on October 18 that Voyager failed to respond.  

    According to a post from NASA, it took a little while to discover that Voyager had switched off its primary X-band transmitter and switched over to its secondary S-band radio transmitter, which uses less power. 

The amazing part is that the S-band transmitter had not been used since 1981!

    Researchers at Kinneret Limnological Laboratory in Israel have found that there are much lower levels of oxygen deep in Lake Kinneret's water basin.

    This is because of an increase in phytoplankton blooms which block out the oxygen, causing fish to suffocate to death.

    They identified two events in 2012 that saw thousands of dead fish had floated to the surface along 2.4 miles of the the lake shore.

    The researchers wrote: '[Our study] may explain the appearance of large numbers of easy-to-collect fish close to the shore described in the biblical narratives.'

Even if this was the mechanism to explain the large number of fish hauled in by the fisherman, it doesn't explain the perfect timing or how the fish only wound up on just one side of the boat. And it is the "coincidence" of timing and location that is often the miracle.

    A new modeling study from a pair of Duke University researchers and their colleagues shows that the oscillation between El Niño and its cold counterpart, La Niña, was present at least 250 million years in the past, and was often of greater magnitude than the oscillations we see today.

    These temperature swings were more intense in the past, and the oscillation occurred even when the continents were in different places than they are now, according to the study, which was recently published in the Proceedings of the National Academy of Sciences.

    Now, details have surfaced about Westinghouse's eVinci microreactor, after the company revealed it had submitted its Preliminary Safety Design Report (PSDR) to the Department of Energy’s National Reactor Innovation Center (NRIC) and in doing so is the first reactor developer to reach this milestone.

    “The completion of the PSDR for the eVinci test reactor is an important step toward enabling a micro reactor developer to perform a test in our DOME facility,” said Brad Tomer, acting director of NRIC.

    “As a national DOE program and part of INL, the nation’s nuclear energy research laboratory, NRIC is committed to working with private companies such as Westinghouse to perform testing and accelerate the development of advanced nuclear technologies that will provide clean energy solutions for the US.”

    NRIC, a key initiative under the DOE, is dedicated to fast-tracking the development and deployment of advanced nuclear technologies like the eVinci microreactor. Its mission includes establishing four new experimental facilities and two large-scale reactor test beds by 2028, with plans to complete two advanced technology experiments by 2030.
