Museum workers pronounce #dobsonfly found in #China, largest aquatic insect

Museum workers pronounce #dobsonfly found in #China, largest aquatic insect | The wonderful universe | Scoop.it

Workers with the Insect Museum of West China, who were recently given several very large dragon-fly looking insects, with long teeth, by locals in a part of Sichuan, have declared it, a giant dobsonfly the largest known aquatic insect in the world alive today. The find displaces the previous record holder, the South American helicopter damselfly, by just two centimeters.

The dobsonfly is common (there are over 220 species of them) in China, India, Africa, South America and some other parts of Asia, but until now, no specimens as large as those recently found in China have been known. The largest specimens in the found group had a wingspan of 21 centimeters, making it large enough to cover the entire face of a human adult. Locals don't have to worry too much about injury from the insects, however, as officials from the museum report that larger males' mandibles are so huge in proportion to their bodies that they are relatively weak—incapable of piercing human skin. They can kick up a stink, however, as they are able to spray an offensive odor when threatened.

 

Also, despite the fact that they look an awful lot like dragonflies, they are more closely related to fishflies. The long mandibles, though scary looking to humans, are actually used for mating—males use them to show off for females, and to hold them still during copulation. Interestingly, while their large wings (commonly twice their body length) make for great flying, they only make use of them for about a week—the rest of their time alive as adults is spent hiding under rocks or moving around on or under the water. That means that they are rarely seen as adults, which for most people is probably a good thing as the giants found in China would probably present a frightening sight. They are much better known during their long larval stage when they are used as bait by fishermen.

NASA’s Hubble Space Telescope has captured the most colorful and detailed image of the early universe — officially dubbed the Ultra Deep Field 2014 — with galaxies that date back to just a few hundred million years after the Big Bang. While many of the blobs in the photo might look like stars, every single point of light is an entire galaxy — around 10,000 of them, in case you were wondering — each containing millions or billions of stars. http://www.peepstalks.com/hubble-captures-the-first-full-color-high-res-photo-of-the-very-early-universe/

The pacemaker of the future might be made of heart cells

The pacemaker of the future might be made of heart cells | The wonderful universe | Scoop.it

Cardiologists in Los Angeles have developed a gene-therapy technique that allows them to transform working heart-muscle cells into cells that regulate a pigs’ heartbeat. This procedure, described today in the Science Translational Medicine, restored normal heart rates for two weeks in pigs that usually rely on mechanical pacemakers. The experiment, researchers say, could lead to lifesaving therapies for people who suffer infections following the implantation of a mechanical pacemaker.

 

"We have been able for the first time to create a biological pacemaker using minimally invasive methods and to show that the new pacemaker suffices to support the demands of daily life," Eduardo Marbán, a cardiologist at the Cedars-Sinai Heart Institute and lead author of the study, told the press yesterday. The approach is practical, added Eugenio Cingolani, a cardiogeneticist also at Cedars-Sinai and a co-author of the study, because "no open-heart surgery is required to inject this gene."

 

In the study, researchers injected a gene called Tbx18 into the pigs’ hearts. This gene, which is also found in humans, reprogrammed a small number of heart-muscle cells into cells that emit electrical impulses and drive the beating of the heart. The area in which this change occurred — about the size of a peppercorn — doesn't normally initiate heartbeats.

 

"We were able to get the biological pacemaker to turn on within 48 hours," Marbán said. To get the gene to the heart, the researchers sent a modified virus into the right ventricle through a catheter. The viral vector isn’t harmful, the researchers said, because the virus they employed was engineered to be "replication deficient" — meaning that it will not reproduce and spread beyond the heart.


Overall, the results of the study demonstrate that the pigs who received the gene therapy experienced an increase in heart rate that allowed them to be much less dependent on backup pacemakers. In contrast, the backup pacemakers were responsible for more than 40 percent of the beats in pigs who didn’t receive the gene therapy, but still underwent surgery.

Single-Cell Genomics Reveals Hundreds of Coexisting Subpopulations in #Ocean Microbes

Single-Cell Genomics Reveals Hundreds of Coexisting Subpopulations in #Ocean Microbes | The wonderful universe | Scoop.it

The smallest, most abundant marine microbe, Prochlorococcus, is a photosynthetic bacteria species essential to the marine ecosystem. An estimated billion billion billion of the single-cell creatures live in the oceans, forming the base of the marine food chain and occupying a range of ecological niches based on temperature, light and chemical preferences, and interactions with other species. But the full extent and characteristics of diversity within this single species remains a puzzle.


To probe this question, scientists in MIT’s Department of Civil and Environmental Engineering (CEE) recently performed a cell-by-cell genomic analysis on a wild population of Prochlorococcus living in a milliliter — less than a quarter teaspoon — of ocean water, and found hundreds of distinct genetic subpopulations.


Each subpopulation in those few drops of water is characterized by a set of core gene alleles linked to a few flexible genes — a combination the MIT scientists call the “genomic backbone” — that endows the subpopulation with a finely tuned suitability for a particular ecological niche. Diversity also exists within the backbone subpopulations; most individual cells in the samples they studied carried at least one set of flexible genes not found in any other cell in its subpopulation.

#Earth's magnetic field is weakening 10 times faster than originally predicted, swarm satellites show

#Earth's magnetic field is weakening 10 times faster than originally predicted, swarm satellites show | The wonderful universe | Scoop.it

Earth's magnetic field, which protects the planet from huge blasts of deadly solar radiation, has been weakening over the past six months, according to data collected by a European Space Agency (ESA) satellite array called Swarm.

 

The biggest weak spots in the magnetic field — which extends 370,000 miles (600,000 kilometers) above the planet's surface — have sprung up over the Western Hemisphere, while the field has strengthened over areas like the southern Indian Ocean, according to the magnetometers onboard the Swarm satellites — three separate satellites floating in tandem.

 

The scientists who conducted the study are still unsure why the magnetic field is weakening, but one likely reason is that Earth's magnetic poles are getting ready to flip, said Rune Floberghagen, the ESA's Swarm mission manager. In fact, the data suggest magnetic north is moving toward Siberia.

 

In fact over the past 20 million years, our planet has settled into a pattern of a pole reversal about every 200,000 to 300,000 years; as of 2012, however, it has been more than twice that long since the last reversal. These reversals aren't split-second flips, and instead occur over hundreds or thousands of years. During this lengthy stint, the magnetic poles start to wander away from the region around the spin poles (the axis around which our planet spins), and eventually end up switched around, according to Cornell University astronomers.

Researchers Create Perfect Quantum Dots with Single-Atom Precision

Researchers Create Perfect Quantum Dots with Single-Atom Precision | The wonderful universe | Scoop.it

A team of physicists from the Paul-Drude-Institut für Festkörperelektronik (PDI) in Berlin, Germany, NTT Basic Research Laboratories in Atsugi, Japan, and the U.S. Naval Research Laboratory (NRL) has used a scanning tunneling microscope to create quantum dots with identical, deterministic sizes. The perfect reproducibility of these dots opens the door to quantum dot architectures completely free of uncontrolled variations, an important goal for technologies from nanophotonics to quantum information processing as well as for fundamental studies. The complete findings are published in the July 2014 issue of the journal Nature Nanotechnology.

 

Quantum dots are often regarded as artificial atoms because, like real atoms, they confine their electrons to quantized states with discrete energies. But the analogy breaks down quickly, because while real atoms are identical, quantum dots usually comprise hundreds or thousands of atoms - with unavoidable variations in their size and shape and, consequently, in their properties and behavior. External electrostatic gates can be used to reduce these variations. But the more ambitious goal of creating quantum dots with intrinsically perfect fidelity by completely eliminating statistical variations in their size, shape, and arrangement has long remained elusive.

 

Creating atomically precise quantum dots requires every atom to be placed in a precisely specified location without error. The team assembled the dots atom-by-atom, using a scanning tunneling microscope (STM), and relied on an atomically precise surface template to define a lattice of allowed atom positions. The template was the surface of an InAs crystal, which has a regular pattern of indium vacancies and a low concentration of native indium adatoms adsorbed above the vacancy sites. The adatoms are ionized +1 donors and can be moved with the STM tip by vertical atom manipulation. The team assembled quantum dots consisting of linear chains of N = 6 to 25 indium atoms; the example shown here is a chain of 22 atoms.

 

Stefan Fölsch, a physicist at the PDI who led the team, explained that "the ionized indium adatoms form a quantum dot by creating an electrostatic well that confines electrons normally associated with a surface state of the InAs crystal. The quantized states can then be probed and mapped by scanning tunneling spectroscopy measurements of the differential conductance." These spectra show a series of resonances labeled by the principal quantum number n. Spatial maps reveal the wave functions of these quantized states, which have n lobes and n - 1 nodes along the chain, exactly as expected for a quantum-mechanical electron in a box. For the 22-atom chain example, the states up to n = 6 are shown.
