Warm-blooded fishes swim faster and farther than cold-blooded counterparts
May 6, 2015
University of California - Santa Barbara
Marine scientists have long known that some species of fish possess a unique physiological characteristic -- a web of arteries and veins lying very close together -- that enables them to raise their internal temperatures higher than that of the water surrounding them.
Now, a new study by an international team of scientists that includes UC Santa Barbara research biologist Jenn Caselle has demonstrated that species possessing the ability to warm their core -- a process called endothermy -- are able to swim two and a half times faster than those whose body temperature doesn't change. In addition, these species, which include some sharks and tunas, can also swim twice as far -- ranges comparable to those of warm-blooded animals such as penguins and other marine mammals. The researchers' findings appear in the Proceedings of the National Academy of Sciences.
"The cost of moving faster and farther is high so there has to be an ecological reason that outweighs the physiological expenditure," Caselle said. "These endothermic fishes are putting a lot more energy into each unit of movement than their cold-blooded counterparts are.
"In fact, the estimated cost of transport is twice as high, but in return they're getting benefits from that increased swimming speed and wider range of migration," she added. "We hypothesize these gains allow these endotherms to be more efficient hunters and to span larger areas in their migration, which probably provides feeding and reproduction benefits."
To conduct the study, the team combined existing data with new information they obtained by attaching sensors -- designed and built by lead author Yuuki Watanabe of Japan's National Institute of Polar Research -- to several sharks in different locations around the world. The researchers' analysis suggests that warmer "red" muscle endothermy permits speedier cruising and greater endurance, which in turn enables these fishes to swim long distances relatively quickly. This characteristic, the marine scientists speculate, allows the fishes to take advantage of seasonally variable food sources.
Of those examined in the study, four shark species are endothermic -- salmon, porbeagle, white and shortfin mako -- as are five species of tuna -- yellow fin, southern bluefin, Atlantic bluefin, Pacific bluefin and albacore. One species in particular, the white shark, has a migration range greater than that of the humpback whale.
Of specific interest, Caselle noted, is the fact that endothermy evolved independently in these distinctly different groups of fishes. The two taxonomic groups diverged more than 450 million years ago, and their common ancestor was most likely cold-blooded. "The mechanisms of convergent evolution aren't always the same, although in this case they pretty much are," Caselle said. "There are only a limited number of ways a fish can rewire.
"This research begins to shed light on possible reasons why these endothermic fish evolved in this way," Caselle concluded. "Our paper contains almost every piece of electronically recorded information in the literature right now -- and that's not a lot. We'd like to be able to expand the use of sensor-captured data to other groups of fishes in order to build a dataset we could analyze to see what different species are doing in terms of their movements and speed."

EXCELLENT VIDEO ~ I'M CURIOUS FROM A TERRESTRIAL VANTAGE POINT ~ WHY THE STROBE FLASHING DOES SO SIMILAR TO A STANDARD FAA REQUIRED ANTI COLLISION BEACON (3 SECOND FLASH)...
FROM THE AIM MANUAL...
4-3-23. Use of Aircraft Lights
a. Aircraft position lights are required to be lighted on aircraft operated on the surface and in flight from sunset to sunrise. In addition, aircraft equipped with an anti-collision light system are required to operate that light system during all types of operations (day and night). However, during any adverse meteorological conditions, the pilot-in-command may determine that the anti-collision lights should be turned off when their light output would constitute a hazard to safety (14 CFR Section 91.209). Supplementary strobe lights should be turned off on the ground when they adversely affect ground personnel or other pilots, and in flight when there are adverse reflection from clouds.
b. An aircraft anti-collision light system can use one or more rotating beacons and/or strobe lights, be colored either red or white, and have different (higher than minimum) intensities when compared to other aircraft. Many aircraft have both a rotating beacon and a strobe light system.

Site Lets People Track Great White Sharks
by Stephen Gutowski May 7 2015
Thanks to a site new website from OCEARCH, people can now track great white sharks in real time as they swim around the globe.
The site, www.ocearch.org, reports the location of sharks which have been tagged with special GPS trackers as they come in.
OCEARCH, which describes itself as “a non-profit organization with a global reach for unprecedented research on great white sharks and other large apex predators,” said opening up its research to the public will help people better understand great white sharks.
“In a collaborative environment established by Founding Chairman and Expedition Leader Chris Fischer, OCEARCH enables leading researchers and institutions to generate previously unattainable data on the movement, biology and health of sharks to protect their future while enhancing public safety and education,” a statement on the group’s About Us page said.
“OCEARCH is a leader in open source research, sharing data in near-real time for free through the Global Shark Tracker, enabling students and the public to learn alongside PhDs. The Landry’s-developed STEM Education Curriculum, based on the Global Shark Tracker and Next Generation Science Standards (NGSS), is being launched for grades 6-8 in the fall of 2013 nationwide.”
The group said the project has included more than 50 researchers and 20 different institutions. They are responsible for “over three dozen research papers in process or completed” in addition to the tracking site.
“Research expeditions are conducted worldwide aboard the M/V OCEARCH, which serves as both a mothership and at-sea laboratory,” the statement said. “Utilizing a custom 75,000 lb. capacity hydraulic platform designed to safely lift mature sharks for access by a multi-disciplined research team, up to 12 studies are conducted in approximately 15 minutes on a live mature shark. Powered by five Cat engines, the M/V OCEARCH is capable of Global Circumnavigation.”
“OCEARCH expeditions – through the support of Caterpillar and other partners such as Costa, Yamaha, Contender, SAFE boats and Mustad–generate satellite tracks and other forms of data for sharks, with planned expansion to other species in the future. Seventeen research expeditions have been conducted to date, with seven more scheduled through the end of 2015.”
OCEARCH expeditions continue to study and tag great white sharks around the world.

Amazon's Delivery Drones Might Track You By Your Phone
Hunting you down...to deliver that dish soap you ordered
Amazon's delivery drone dream is very slowly inching toward reality, and a recently published patent gives some insight to the way the service would probably work.
First and foremost, it wouldn't just be a replacement for UPS with drones just mindlessly dropping packages at your door all the time. Instead, Amazon envisions a system where the drones actually track you via your phone. The hope is that would help the drones pick the optimal delivery destination. Maybe the office as opposed to home, or a moving target like that boat you totally own, or even 10 feet in front of you on the sidewalk. That, or hunt you down during the robot apocalypse.

Renowned historians and researchers, Richard M. Dolan and Don Schmitt discuss the mysterious Roswell alien slides, which were revealed to the public during a conference which both had attended earlier in the day. The conference, organized by Mexican journalist and ufologist Jaime Maussan, featured a number of experts, who'd spent months carefully analyzing the two slides. The slides were authenticated to be from the 1940s, and were from the collection of Hilda Ray, a now deceased attorney and pilot, who was married to a geologist, Bernerd Ray, said to be working in the Roswell, New Mexico area in 1947. Further, the Rays were personally acquainted with Dwight and Mamie Eisenhower.
Dolan noted that the experts found the creature depicted in the slides to be anomalous, and though damaged or decomposed it was not mummified. Nor was it believed to be a mammal or human. There is a minor blur in the images, which suggests that the photos were taken quickly or surreptitiously, and one of the last surviving persons said to witness the Roswell creature, stated that the image in the slide looks remarkably like what he saw, Dolan recounted. The slides won't be debunked easily, but neither are they definitive evidence without an actual body.

Congress Tells Court That Congress Can’t Be Investigated for Insider Trading
Thats right! None of you MoFos is steppin on my Dinner plate!
In a little-noticed brief filed last summer, lawyers for the House of Representatives claimed that an SEC investigation of congressional insider trading should be blocked on principle, because lawmakers and their staff are constitutionally protected from such inquiries given the nature of their work.
The legal team led by Kerry W. Kircher, who was appointed House General Counsel by Speaker John Boehner in 2011, claimed that the insider trading probe violated the separation of powers between the legislative and executive branch.
In 2012, members of Congress patted themselves on the back for passing the STOCK Act, a bill meant to curb insider trading for lawmakers and their staff. “We all know that Washington is broken and today members of both parties took a big step forward to fix it,” said Rep. Bill Johnson, R-Ohio, upon passage of the law.
But as the Securities and Exchange Commission made news with the first major investigation of political insider trading, Congress moved to block the inquiry.
The SEC investigation focused on how Brian Sutter, then a staffer for the House Ways and Means Committee, allegedly passed along information about an upcoming Medicare decision to a lobbyist, who then shared the tip with other firms. Leading hedge funds used the insider tip to trade on health insurance stocks that were affected by the soon-to-be announced Medicare decision.
Calling the SEC’s inquiry a “remarkable fishing expedition for congressional records,” Kircher and his team claimed that the SEC had no business issuing a subpoena to Sutter. “Communications with lobbyists, of course, are a normal and routine part of Committee information-gathering,” the brief continued, arguing that there “is no room for the SEC to inquire into the Committee’s or Mr. Sutter’s purpose or motives.”
Wall Street investors routinely hire specialized “political intelligence” lobbyists in Washington to get insider knowledge of major government decisions so that they may make trades using the information. But little is known about the mechanics of political intelligence lobbying, which falls outside the scope of traditional lobbying law, and therefore does not show up in mandatory lobbying disclosure reports.
There are occasional hints, though.
Personal finance forms reveal that from July of 2011 through May of 2013, David Berteau served as a consultant to Height Analytics, the political intelligence firm at the center of the SEC’s current probe. At the time of his work for Height Analytics, Berteau simultaneously worked as a vice president at the Center for Strategic and International Studies, a prominent think tank in Washington. Berteau is now the Assistant Secretary of Defense for Logistics and Materiel Readiness.
Congressional travel forms show that on December 12, 2012, Emily Porter, at the time an employee of Boehner’s office, traveled to New York on a sponsored trip to meet with JNK Securities for a group lunch with business clients. According to the Wall Street Journal, JNK “has emerged as one of the most aggressive” political intelligence firms on Capitol Hill.
This is hardly the first time Congress has moved to undermine its own ethics rules. In 2011, congressional Republicans quickly abandoned their promise to post the text of bills online “for at least three days” before voting on them.
