The enzyme that makes fireflies glow is lighting up the scientific path toward a long-sought new medical imaging agent to better monitor treatment with heparin, the blood thinner that millions of people take to prevent or treat blood clots, scientists are reporting. Their study appears in the ACS' monthly journal Bioconjugate Chemistry. Bruce Branchini and colleagues describe a need for new medical imaging agents that emit near-infrared light "” the light rays that "night vision"...

Research uncovers secrets of strange mollusk and its use of light as a possible defense mechanism Two scientists at Scripps Institution of Oceanography at UC San Diego have provided the first details about the mysterious flashes of dazzling bioluminescent light produced by a little-known sea snail. Dimitri Deheyn and Nerida Wilson of Scripps Oceanography (Wilson is now at the Australian Museum in Sydney) studied a species of "clusterwink snail," a small marine snail typically found in tight...

LONG BEACH, Calif., Dec. 6, 2010 /PRNewswire/ -- For generations, the mystery lights of Marfa, Texas, have entertained residents with their strange dancing. On some warmer nights, a ball of light seems to split into two, which will separate and fly away from each other before turning around and flying back together. They have recently been linked to flying lights in the southwest Pacific, lights that natives of Papua New Guinea testify are from large flying creatures. In southwest Texas,...

Scientists in Southampton, UK, and Ulm and Karlsruhe in Germany have shown that a variant form of a fluorescent protein (FP) originally isolated from a reef coral has excellent properties as a marker protein for super-resolution microscopy in live cells. Their findings have been published online by Nature Methods and will appear in print in the upcoming August issue of that journal. Fluorescent proteins produced by a range of marine animals glow with a rainbow of colors, adding to the visual...

First experiments suggest that synchronous male flashing is more recognizable to females For decades, scientists have speculated about why some fireflies exhibit synchronous flashing, in which large groups produce rhythmic, repeated flashes in unison "“ sometimes lighting up a whole forest at once. Now, the first experiments on the function of this phenomenon suggest that synchronous flashing preserves female fireflies' recognition of suitable mates. The results are reported in the July...

The discovery of how bacteria communicate may lead to new types of antibiotics and ways of improving actions of good bacteria Bonnie Bassler spends her days listening to bacteria talk to one another, and what she has overheard may surprise you. It turns out that these tiny, single-celled organisms are taking roll call. Each whispered conversation is an attempt to count how many of their own kind are present before they try to mount an attack on their host organism, which might very well be...

Tiny chemical sensors implanted into patients could help diagnose disease and track its progress, following a development by scientists. Researchers have developed tiny probes comprising gold-coated particles. These can be inserted into cells, enabling diseases to be detected and monitored remotely using light from a laser. Once the probe is inside a cell, laser light shone on to it is absorbed then re-emitted, causing nearby proteins in the cell to vibrate according to their shape. Because...

 The Rosetta Stone of bacterial communication may have been found.Although they have no sensory organs, bacteria can get a good idea about what's going on in their neighborhood and communicate with each other, mainly by secreting and taking in chemicals from their surrounding environment. Even though there are millions of different kinds of bacteria with their own ways of sensing the world around them, Duke University bioengineers believe they have found a principle common to all of...

U.S. researchers found a new method effectively revealed the amount of bacteria in plaque near braces. The study, published in American Journal of Orthodontics and Dentofacial Orthopedics, also found certain orthodontic appliances, or braces, were more prone to bacteria. Researchers from Portland's Oregon Health & Science University found a biochemical technique that measured adenosine triphosphate driven bioluminescence was a reliable chair-side tool to rapidly quantify oral bacteria...

Humpback Anglerfish, Melanocetus johnsonii
2013-10-09 11:29:50

The Humpback Anglerfish (Melanocetus johnsonii), or common black devil, is a deep-sea anglerfish belonging to the family Melanocetidae, found in tropical to temperate portions of all oceans at depths of up to 6,600 feet. Male humpback angler fish are much smaller in size compared to the females, being no more than 3 centimeters long, whereas the female usually achieves a length of 7 inches long. Humpback angler fish remain free swimming into adulthood, which isn’t the case with other...

Bathocyroe fosteri is a species of lobate ctenophore found in all oceans around the world. It is typically found at intermediate depths and is very abundant near the Mid-Atlantic Ridge. This deep-sea comb jelly is named for Alvin (DSV-2) pilot Dudley Foster, who is credited with first collecting the specimens. This specimen measures about two inches tall and is bioluminescent. This species, as well as other ctenophores, reproduce sexually, with little to know self-fertilization known....

Angler, Lophius piscatorius
2012-04-02 16:12:16

The Angler, (Lophius piscatorius), also known as the Fishing-frog, Frog-fish, or Sea-devil, is a species of monkfish in the family Lophiidae. It is found in coastal waters of the northeast Atlantic, from the Barents Sea to the Strait of Gibraltar, the Mediterranean and the Black Sea. This species comprises a significant commercial fishery in parts of its range. The Angler has a very large, broad head that is flat and depressed. The rest of the body appears to be a mere appendage. The wide...

Double anglers are a family, Diceratiidae, of anglerfish. They are found in deep, lightless waters of the Atlantic, Indian and western Pacific Oceans. They are easily distinguished from other anglerfish by their possession of a second light-bearing dorsal fin spine immediately behind the illicium (the bioluminescent lure present in other anglerfish). As in other anglerfish, males are very much smaller than the females and, after a larval and adolescent free-living stage, spend the rest...

The Cookiecutter shark, Isistius brasiliensis, also known as the cigar shark or luminous shark, is a small rarely-seen dogfish shark. Anatomy and morphology The Cookiecutter sharks often glow green and grow up to 20 in (50 cm) long. The underside of the shark is bioluminescent, glowing a pale blue-green that matches the background light from the ocean's surface that serves as camouflage to creatures beneath it. However, a small non-luminescent patch appears black deceiving the shark's...
