Study on Magnetic Compass Orientation in Birds Builds Case For Bio-Inspired Sensors

Researchers working on DARPA’s Quantum Effects in Biological Environments (QuBE) program have shown that the electromagnetic noise that permeates modern urban environments can disrupt a bird’s internal magnetic compass. The findings settle a decades-long debate into whether low-level, artificial electric and magnetic fields can affect biological processes in higher vertebrates. For DARPA, the results hint at a new class of bio-inspired sensors at the intersection of biology and quantum physics.

Sparrow Populations Collapsing in Japan

on Thursday, 19 January 2012. Posted in Biology, Sci/Tech

SparrowSparrows, maybe the most familiar of all wild birds, are a vanishing species. The population of sparrows in Japan has made a sudden drop, just as they have in Europe.

This is a slight mystery, but researchers point to urban sprawl and modern styles of architecture that have deprived the birds of their natural habitat and their usual nesting places in towns and cities, as well as a lack of food, particularly insects.

According to the researchers, the number of sparrows in Japan has fallen by 60 percent in over the past 21 years. The estimate by a team at Rikkyo University in Tokyo and Iwate Medical University in Iwate Prefecture is based on the results of monitoring by the Yamahsina Institute for Ornithology. Gen Morimoto, a researcher at Rikkyo University's Lab of Animal Ecology, and Osamu Mikami, an assistant professor of biology at Iwate Medical University, are members of the team.

Study Reveals How Bats Stay on Target Even in Dark, Cluttered Environment

on Friday, 29 July 2011. Posted in Biology, Sci/Tech

New research shows bats can stay on target even in a cluttered environment. In a paper published in the July 29 issue of Science, James Simmons and Mary Bates of Brown University, along with researchers from the Republic of Georgia, reveal how bats expertly use echolocation to hone in on specific targets, such as prey organisms, without being distracted or set off course by background objects in their environments.

It has long been known that bats emit high frequency sonar blasts, and then construct a three dimensional picture of their environment based on returning echoes. But the new research, which was partially funded by the National Science Foundation, shows how bats interpret the cacophony of returning echoes to distinguish their priority target from background clutter.

Simmons explains that when a bat chirps, it waits for the corresponding echo; it makes a mental fingerprint of the emitted sound and its echo. If the broadcast/echo fingerprints match up precisely, then the bat "will process it and produce an image," Simmons said. In many cases, that image would be the bat's target object. But when the second harmonic is weaker in the echo fingerprint, the response from the bat's neurons' is delayed by as few as 3 microseconds. That momentary delay, while undetectable to humans, is enough to tell the bat that the object is present, but it is not its primary interest.

Man Claims to Photograph Loch Ness Monster

on Saturday, 23 July 2011. Posted in Biology, Sci/Tech

William Jobes believes he took a picture of the Loch ness MonsterIs there an unknown creature swimming in the cold depths of Scotland’s famous Loch Ness? Despite stories dating back to the Middle Ages about large, mysterious creatures inhabiting the Loch, no hard evidence of “Nessie’s” existence has ever come to light.

Every so often, however, someone claims to snap a picture of the elusive alleged “monster.”

After 45 years of trying, William Jobes believes he has evidence of the fabled creature’s existence.

The UK’s Daily Mail reports that the 62-year-old was walking along a footpath with his wife when he spotted something unusual in the water.

Whatever it was, it appeared to have a head that was bobbing about above the waves some 200 to 300 yards from shore. He managed to get a single picture with his camera.

“I had a wonderful shock,” Jobes told the paper. “I have actually been coming up to Inverness for the past 45 years and I have never seen anything like this before.”

The picture snapped by Jobes appears to depict a dark colored hump in the water with a smaller stub that looks like it could be a tale rising a short distance from the water’s surface not far behind the main hump. Or, maybe it’s the creature’s head. Or, maybe it is nothing at all.

Jellyfish Point Way to Better Turbines

on Friday, 15 July 2011. Posted in Biology, Sci/Tech

Moon Jellyfish may be the key to getting rid of those unsightly wind turbines. Chances are that where there are wind turbines, there are also signs staked in the front yards of surrounding neighbors opposing their intrusive, unsightly, and health damaging effects. Bioengineering professor John Dabiri from the California Institute of Technology just may have come up with a solution that may harness energy more efficiently using smaller, less ghastly spectacles spinning in the skyline. And he got his inspiration by studying the moon jellyfish.

Why the moon jellyfish? Moon Jellyfish generally move close to the water's surface, depending largely upon water currents, tides, and winds to move them along as they feed on an array of zooplankton. Although an efficient way to travel, the moon jellyfish doesn’t depend just on mother nature. Instead, the jellyfish expands and contracts the jelly within its bell-shaped body forcing the water away from the jellyfish and allowing it to be thrust through the water.

Reporting on Dabiri's work, Discovery News noted: “Through his research, Dabiri has observed that moon jellyfish don't move through water simply by using jet propulsion. Instead, they create complex vortex rings in the wake of their motion that allow them propel themselves forward.”

Dabiri believes that a better understanding of the jellyfish's method could hold the key to creating more efficient human propulsion devices. In addition, “Dabiri is also interested in the schooling of fish and the hypothesis that patterns of the school's group motion actually lowers the amount of energy each fish exerts. The theory is encouraging for alternatives to large, unsightly turbines — the idea being that smaller, clustered structures might be a more efficient way to harness wind power.”

Researchers Learn How to Erase Memories

on Thursday, 23 June 2011. Posted in Biology, Sci/Tech

Researchers learn to erase memories which is reminiscent of Heroes and Star Trek. In the once popular NBC science fiction drama Heroes, people who remember problematic or unfortunate things have their minds erased by a character known as “the Haitian.”

This enigmatic man was used by a super-secret conspiratorial organization known only as “the company” to selectively remove memories from people who might threaten the organization’s diabolical agendas. Many of the characters on the show rightly viewed “the Haitian” with dread.

What was science fiction sooner or later becomes science fact. Computer floppy disks, ubiquitous in the 1980s and 90s, were predicted by Gene Roddenberry’s Star Trek in the 1960’s. Nuclear submarines, famously, were predicted in the 19th century author Jules Verne, as were trips to the Moon.

Now, while “the Haitian” won’t be supernaturally removing memories any time soon, scientists have discovered how to remove, or turn off, memories — at least in rats in the laboratory.

A research team lead by Theodore W. Berger of the Department of Biomedical Engineering at the University of Southern California published a paper describing their research in the Journal of Neural Engineering on June 15.

Ten-year Study Finds California Current an Oceanic Serengeti Plain

on Wednesday, 22 June 2011. Posted in Biology, Sci/Tech

The Census of Marine Life Tagging of Pacific Predators project (TOPP) found the ocean teeming with life. After ten years of tagging and tracking 23 of the Pacific Ocean’s top predators, the Census of Marine Life Tagging of Pacific Predators project (TOPP) has found that some areas of the Pacific teem with so much life that they are like oceanic equivalents of Africa’s famed Serengeti Plain.

The results of the study, published in the journal Nature, found that one of the “hot spots” for marine wildlife is the California current. Flowing off the U.S. west coast, the California current moves south, beginning off the coast of southern British Columbia and flowing toward Baja California. Unique climactic conditions coupled with the current have long been known to produce an upwelling effect that results in cool, nutrient-rich water supporting a vibrant food chain.

The study also identified another area of the Pacific preferred by marine wildlife. According to the Census of Marine Life, this area, known as the North Pacific Transition Zone that connects the western and eastern Pacific, also teems with life.

You know you live in the country when your power grid is unreliable. No, it’s not unreliable because the technology is bad or outdated or the guy putting up and maintaining the power lines is sub-par. The real reason the grid is unreliable in rural America is because of mother nature.
