These are prehistoric animals compared to their modern relatives and, for scale, a human. A human who’s interested in what they’re like… except when…
Look out! HELL PIG!
There are plenty more of the majestic giants (and some terrifying ones) at NPR’s Skunk Bear tumblog.
The New Horizons Long Range Reconnaissance Imager (LORRI) snapped this photo of Jupiter’s ring system on February 24, 2007, from a distance of 7.1 million kilometers (4.4 million miles).
This processed image shows a narrow ring, about 1,000 kilometers (600 miles) wide, with a fainter sheet of material inside it. The faint glow extending in from the ring is likely caused by fine dust that diffuses in toward Jupiter. This is the outer tip of the “halo,” a cloud of dust …

ABSTRACT: The planet Jupiter is 35 light-minutes from Earth (give or take a couple of minutes depending on where in its orbit the planet is).
So a robot floating in the turbulent winds of Jupiter would take that long to send a mes…
Three names for one little fish. And those are just the beginning.
I found this one on the Scientific Illustration tumblog, which quoted Wikipedia on the doree (etc.):
John Dory, St Pierre or Peter’s Fish, refers to fish of the genus Zeus, especially Zeus faber, of widespread distribution. It is an edible benthic coastal marine fish with a laterally compressed olive-yellow body which has a large dark spot, and long spines on the dorsal fin. The dark spot is used to flash an ‘evil ey…
These are ostensibly Cochin chickens, or forerunners of what we’d call Cochins today. They’re a breed with a *lot* of character, and are uniquely suited, temperamentally, for being “pet” chickens moreso than egg factories or walking meat supplies. Despite the name (after a part of India), they’re originally from China.
It’s the most Earth-like planet yet discovered. Kepler 452b sits in the “Goldilocks” zone around its star, not too hot and not too cold, and is about the same size (or is a little larger) and made of something like the same stuff as the planet we’re sitting around on right now. It takes 365 days to orbit around its sun, too. NASA’s calling it ou…
Popular Science warns us to slow down by construction sites and watch for self-driving trucks on Florida roads by year’s end: The rigs, which are part of a Department of Transportation pilot program, can navigate by following a pre-programmed lead car, via remote control, or by using GPS Waypoint navigation. Daimler’s self-driving tractor trailers have already been testing in Nevada under a special state-granted autonomous license. But like the Google autonomous cars on the road in California, Daimler’s trucks require a human driver to be on board—the vehicles scheduled to deploy to the Sunshine State don’t. The modified medium-duty Freightliners will be used for highway construction projects, and safety was cited as a key factor in removing from the driver from the equation. Video at the link.
Science magazine has an exclusive report on a fusion group that could change everything. They’ve got a reactor that works better than any power source we’ve seen yet: A privately funded company called Tri Alpha Energy has built a machine that forms a ball of superheated gas—at about 10 million degrees Celsius—and holds it steady for 5 milliseconds without decaying away. That may seem a mere blink of an eye, but it is far longer than other efforts with the technique and shows for the first time that it is possible to hold the gas in a steady state—the researchers stopped only when their machine ran out of juice. “They’ve succeeded finally in achieving a lifetime limited only by the power available to the system,” says particle physicist Burton Richter of Stanford University in Palo Alto, California, who sits on a board of advisers to Tri Alpha. … …[T]he main efforts in this field are […]
Nature tries to figure out why we’re not making the headway we should against Lyme, Rocky Mountain spotted fever, and the rest of the tick-borne nasties: [Scott] Williams is testing whether vaccinating mice against Borrelia burgdorferi, the bacterium that causes Lyme disease in the United States, can reduce the proportion of ticks that are infected. Health officials are looking on with interest. Connecticut has one of the highest rates of human Lyme disease in the country, and June is peak time for transmission. Borrelia burgdorferi infects an estimated 329,000 people in the United States each year, according to the US Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia. And although most people who get prompt treatment recover quickly — Williams has had Lyme three times — up to one in five develops long-term and potentially life-threatening symptoms, including heart, vision or memory problems, or debilitating joint pain. … Even the time-honoured protective strategies […]
Wired brings up the potential of a universal flu vaccine – and the problems getting one together: Today, independent teams reported in Science and Nature Medicine how they’ve tinkered with a piece of viral protein so it can teach immune systems—in this case, in mice, ferrets, and monkeys—to fight whole groups of viruses rather than just a single strain. “It’s a great first step in the road for generating a universal flu vaccine,” says Gary Nabel, who oversaw one of the studies as former head of the National Institutes of Health’s Vaccine Research Center. … Influenza viruses are covered in lollipop-shaped proteins called hemagglutinin, which they use to sneak into cells. Get familiar with hemagglutinin, or HA, because I’ll be talking about it a lot. The immune system produces molecules called antibodies that bind to and neutralize the head of HA, which, inconveniently for humans, mutates over and over to escape detection. The HA head […]

Nature reports that, in the face of extinction, frogs have a way to adapt to pesticides – a little: Several species of frogs can quickly switch on genetic resistance to a group of commonly used pesticides. In one case, wood frogs (Lithobates sylvaticus) were able to deploy such defences in just one generation after exposure to contaminated environments, scientists reported last week at a conference of the Ecological Society of America in Baltimore, Maryland. This is the first-known example of a vertebrate species developing pesticide resistance through a process called phenotypic plasticity, in which the expression of some genes changes in response to environmental pressure. It does not involve changes to the genes themselves, which often take many generations to evolve. … In 2013, [Rick] Relyea [of the Rensselaer Polytechnic Institute] and his team discovered that L. sylvaticus frogs living near agricultural land in northwest Pennsylvania were resistant to the pesticide carbaryl. Laboratory tests revealed […]
Denmark’s The Local shares the excitement of discovering a 400-year-old dragon – a figurehead from a Danish ship – that has been hidden in the sea since the 1500s: The wooden face, which resembles a monster or a large grinning dog, had been lying on a seabed off the southern Swedish town of Ronneby for more than five centuries. It is thought to have broken off from the Gribhunden ship, commissioned by King Hans, who ruled Denmark from 1481 to 1513. The ship sunk after a fire. … Marcus Sandekejer from Blekinge museum, which is set to put the discovery on display later this month, told The Local on Wednesday: “This figurehead is probably the only one left from a 15th century ship in the world.” He said it was a “fantastic feeling” watching expert archaeologists lift the creature out of the water. “520 years under water….and in such a great condition!” The museum is […]
German researchers, as disclosed in Science Daily, have found a singularly creative language – a form of whistled Turkish that, unlike any other language on Earth, is not processed only on the left side of the brain: “We are unbelievably lucky that such a language indeed exists,” says Onur Güntürkün of Ruhr-University Bochum in Germany. “It is a true experiment of nature.” Whistled Turkish is exactly what it sounds like: Turkish that has been adapted into a series of whistles. This method of communicating was popular in the old days, before the advent of telephones, in small villages in Turkey as a means for long-distance communication. In comparison to spoken Turkish, whistled Turkish carries much farther. While whistled-Turkish speakers use “normal” Turkish at close range, they switch to the whistled form when at a distance of, say, 50 to 90 meters away. … Whistled Turkish isn’t a distinct language from Turkish, Güntürkün explains. It is […]
BBC reveals a dirty secret about our sooty cities – the grunge doesn’t trap air pollution – it creates it: In rooftop experiments in Germany, the researchers tracked the content of grime in both sunshine and shade. They say sunlit grime releases nitrogen in two forms: the toxic pollutant nitrogen dioxide (NO2), plus nitrous acid – a key driver of smog formation. The findings, presented at a conference of the American Chemical Society in Boston, were welcomed by pollution experts – and may explain a “missing” source of smog-producing gas in the skies of London. … On a tower above the city they set up two large shelves filled with beads of window glass. Both sets of beads received the same air flow – and got thoroughly grimy – but only one was in the sun.
The Denver Post‘s (ahem) “nerd blog” has some interesting things to say about the planet next door – which, University of Colorado researchers believe, might have been alive more recently than we thought: An 18-square-mile chloride salt deposit is thought to have once been a lake bed with water that had only 8 percent the salinity of earth’s oceans, and may have been home to life. The dried up pond — “one of the last instances of a sizable lake on Mars,” according to the study’s lead researcher — was digitally mapped by a team from CU’s Laboratory for Atmospheric and Space Physics, along with researchers from two other universities. The study was published earlier this month in the journal Geology. … The salt deposits share some similarities with Utah’s Bonneville Salt Flats, according to the release from CU. An advantage of such deposits is that the salt can contain fossilized microbial life. “It can […]
Three names for one little fish. And those are just the beginning. I found this one on the Scientific Illustration tumblog, which quoted Wikipedia on the doree (etc.): John Dory, St Pierre or Peter’s Fish, refers to fish of the genus Zeus, especially Zeus faber, of widespread distribution. It is an edible benthic coastal marine fish with a laterally compressed olive-yellow body which has a large dark spot, and long spines on the dorsal fin. The dark spot is used to flash an ‘evil eye’ if danger approaches. Its large eyes at the front of the head provide it with binocular vision and depth perception, which are important for predators. The John Dory’s eye spot on the side of its body also confuses prey, which are scooped up in its big mouth.
Science Daily introduces a new way to recharge your battery – take this flexible, biodegradable device and power it up by touching it: Many people may not realize it, but the movements we often take for granted — such as walking and tapping on our keyboards — release energy that largely dissipates, unused. Several years ago, scientists figured out how to capture some of that energy and convert it into electricity so we might one day use it to power our mobile gadgetry. … The researchers built a nanogenerator using a flexible, biocompatible polymer film made out of polyvinylidene fluoride, or PVDF. To improve the material’s energy-harvesting ability, they added DNA, which has good electrical properties and is biocompatible and biodegradable. Their device was powered with gentle tapping, and it lit up 22 to 55 light-emitting diodes. — Video at the link. (Kind of unintentionally funny – it’s more “spanking” than “tapping” at this point.

Nature reports that the octopus has, for an invertebrate, a really large genome – including a long sequence of genes that regulates intelligence in “higher” animals: “It’s the first sequenced genome from something like an alien,” jokes neurobiologist Clifton Ragsdale of the University of Chicago in Illinois, who co-led the genetic analysis of the California two-spot octopus (Octopus bimaculoides). … Researchers want to understand how the cephalopods, a class of free-floating molluscs, produced a creature that is clever enough to navigate highly complex mazes and open jars filled with tasty crabs. Surprisingly, the octopus genome turned out to be almost as large as a human’s and to contain a greater number of protein-coding genes — some 33,000, compared with fewer than 25,000 in Homo sapiens. … One of the most remarkable gene groups is the protocadherins, which regulate the development of neurons and the short-range interactions between them. The octopus has 168 of these genes […]
New York Times reveals what might be the ultimate fate of the Lost Colony of Roanoke: They call the spot Site X. Down a dusty road winding through soybean fields, the clearing lies between two cypress swamps teeming with venomous snakes. It is a suitably mysterious name for a location that may shed light on an enigma at the heart of America’s founding: the fate of the “lost colonists” who vanished from a sandy outpost on Roanoke Island, about 60 miles east, in the late 16th century. On and off for three years, Mr. [Nicholas] Luccketti and colleagues with the First Colony Foundation have been excavating parts of the hillside, hoping to find traces of the colonists. As if clues in a latter-day treasure hunt, hidden markings on a 16th-century map led them to the spot on the sound’s western shore, which Mr. Luccketti had previously surveyed. Mr. Luccketti, 66, chose his words carefully as […]
