Judith Mank leads a tour of how sex is genetically programmed and how sex differences evolve. Watch the Q&A here: https://www.youtube.com/watch?v=v-DRO… Subscribe for regular science videos: http://bit.ly/RiSubscRibe Males and females in many species are often quite different from one another. The sex of an individual can have profound effects on how an organisms behaves, how it looks, how it lives and, in some cases, even how it dies. These differences are the product of different evolutionary forces acting on males and females, sometimes creating substantial conflicts between the sexes. In this talk, Judith Mank gives a quick tour of how sex is genetically programmed and how sex differences evolve. Judith Mank is Professor in the Department of Genetics, Evolution and Environment at University College London. She is interested in understanding how form, behaviour and reproductive patterns have evolved through selective pressures.

President Trump Issues Emergency Order Grounding Boeing 737 Max 8,9, Aircraft…


Re-Posted from The Conservative tree house on March 13, 2019 by 

Following two similar plane crashes in Indonesia (Oct ’18) and Ethiopia (March ’19) President Trump has issued an emergency order grounding a specific Boeing 737 airliner.  The “Max 8” and “Max 9” models are being grounded out of an abundance of caution while U.S. and international authorities await the findings from crash investigation.

.

WASHINGTON (AP) — The U.S. is issuing an emergency order Wednesday grounding all Boeing 737 Max 8 and Max 9 aircraft “effective immediately,” in the wake of the crash of an Ethiopian Airliner that killed 157 people, President Donald Trump said.

“All of those planes are grounded, effective immediately,” Trump said during a scheduled briefing on border security.

Trump said any airplane currently in the air will go to its destination and then be grounded. He added all airlines and affected pilots had been notified.

Trump said the safety of the American people is of “paramount concern,” and added that the FAA would soon put out a statement on the action.

Trump said the decision to ground the aircraft “didn’t have to be made, but we thought it was the right decision.”

The president insisted the announcement was coordinated with aviation officials in Canada, U.S. carriers and aircraft manufacturer Boeing.

“Boeing is an incredible company,” Trump said. “They are working very, very hard right now and hopefully they’ll quickly come up with an answer.” (AP Report Link)

Prior to this decision, it appeared that Boeing was concerned about a specific element to flight software – SEE HERE:

BOEING – March 11, 2018 […] For the past several months and in the aftermath of Lion Air Flight 610, Boeing has been developing a flight control software enhancement for the 737 MAX, designed to make an already safe aircraft even safer. This includes updates to the Maneuvering Characteristics Augmentation System (MCAS) flight control law, pilot displays, operation manuals and crew training. The enhanced flight control law incorporates angle of attack (AOA) inputs, limits stabilizer trim commands in response to an erroneous angle of attack reading, and provides a limit to the stabilizer command in order to retain elevator authority.

Boeing has been working closely with the Federal Aviation Administration (FAA) on development, planning and certification of the software enhancement, and it will be deployed across the 737 MAX fleet in the coming weeks. The update also incorporates feedback received from our customers.

The FAA says it anticipates mandating this software enhancement with an Airworthiness Directive (AD) no later than April. We have worked with the FAA in development of this software enhancement.

[…] A pitch augmentation control law (MCAS) was implemented on the 737 MAX to improve aircraft handling characteristics and decrease pitch-up tendency at elevated angles of attack. It was put through flight testing as part of the certification process prior to the airplane entering service. MCAS does not control the airplane in normal flight; it improves the behavior of the airplane in a non-normal part of the operating envelope. (read more)

Why SpaceX’s Starship will fall like a skydiver and not fly like an airplane

Ever since SpaceX tweeted this photo on September 13th, 2018, a lot of people fear the BFR is slowly turning into the space shuttle. Quoting ever growing wings and a giant heat shield covering the belly of the ship… so how is this any different than the Space Shuttle? Today we’ll to cover three topics. First, we’ll compare the reentry of the space shuttle to the reentry of the BFS and show how they differ. Then we’ll explain what control surfaces allow the BFS to perform this reentry, and then we’ll compare the thermal protection systems of the Shuttle and the BFS.

This is a video of every SpaceX landing or landing attempt of which a video was taken. I tried to edit it down as much as possible but it still ended up pretty long, mainly due to including Grasshopper and F9R flights (I didn’t feel I could use the word “every” if I didn’t). I made this because I couldn’t find any such compilations on Youtube. Most videos are from SpaceX’s Youtube Channel. Thanks for watching and thanks to SpaceX for all the excitement. Here is the full list of all launches that I used as my notes while putting this together: 1. 9-21-2012 Grasshopper Hop 2. 11-01-2012 Grasshopper 2 story 3. 12-17-2012 Grasshopper 12 story 4. 03-07-2013 Grasshopper 24 story 5. 04-17-2012 Grasshopper 250m 6. 06-14-2013 Grasshopper 325m Full Precision Sensor Suite 7. 08-13-2013 Grasshopper 250m, 100m Lateral Divert 8x. 09-29-2013 Falcon 9 Cassiope, Failure, Aerodynamically unstable, video of reentry burn here: https://youtu.be/RtDbDMRG3q8?t=128 9. 10-07-2013 Grasshopper 744m Final Flight 10. 04-17-2014 Falcon 9R 250m 11x. 04-18-2014 Falcon 9 CRS-3 Ocean Landing, Link to vid: https://www.youtube.com/watch?v=CjZ33… 12. 05-01-2014 Falcon 9R 1000m 13. 06-17-2014 Falcon 9R 1000m Grid Fins 14. 07-14-2014 Falcon 9 Orbcomm-1 Ocean Landing 15x. 08-01-2014 Falcon 9R ???

May 5 (Bloomberg) — Bloomberg’s “The Next Space Race” is a journey through the booming business of space exploration. The International Space Station is a near zero-gravity laboratory dedicated to scientific research. The end of NASA’s shuttle program in 2011 left the world with only one way to get there, buy a seat from the Russians. NASA is holding a competition challenging private enterprise to build America’s next spacecraft. Boeing, SpaceX, and Sierra Nevada are all multi-billion dollar aerospace companies competing to win the NASA contract that could cement dominance in the emerging space industry.
