SIM - Structured Illumination Microscopy

SIM - Structured Illumination Microscopy
The view inside living cells is getting clearer. Scientists at Howard Hughes Medical Institute are pushing the abilities of super-resolution microscopes to record the actual processes going on inside the smallest units of life in real time. 

New insights are already flowing from the imaging instruments behind structured illumination microscopy (SIM). One SIM technique has achieved a resolution of 62 nanometers, small enough to watch proteins move, cellular transport of molecules and cytoskeletal dynamics. What’s more, SIM views into the cell delicately, avoiding using so much light that it alters or damages normal functioning. It can also acquire images much faster, allowing scientists to see minute changes within the cell.

Distant Neutrinos Detected Below Antarctic Ice


Distant Neutrinos Detected Below Antarctic Ice
 From where do these neutrinos come? The IceCube Neutrino Observatory near the South Pole of the Earth has begun to detect nearly invisible particles of very high energy. Although these rarely-interacting neutrinos pass through much of the Earth just before being detected, where they started remains a mystery.

Pictured here is IceCube's Antarctic lab accompanied by a cartoon depicting long strands of detectors frozen into the crystal clear ice below. Candidate origins for these cosmic neutrinos include the violent surroundings of supermassive black holes at the centers of distant galaxies, and tremendous stellar explosions culminating in gamma ray bursts far across the universe. As IceCube detects increasingly more high energy neutrinos, correlations with known objects may resolve this cosmic conundrum -- or we may never know.

The largest species of jellyfish, the lion’s mane, has tentacles that can extend more than 100 feet, longer than a blue whale.
The Lion’s mane jellyfish is a large species of jelly that tends to vary in color. Larger jellies can range from bright red to dark purple, while smaller ones are typically to tan to orange. This species earned its name from its red and yellow tentacles, which resemble the color of a lion’s mane.

Like other jellies, the Lion’s mane jellyfish is capable of asexual reproduction early in life. But when it reaches full maturity, it reproduces sexually. The female jellyfish will carry the fertilized eggs in her tentacles until they become larvae.

Umbonia Spinosa


Umbonia Spinosa
These thorn bugs are related to cicadas, and use their beaks to pierce plant stems to feed upon their sap. Their strange appearance still poses many questions to scientists.

Females lay their eggs in the tender bark of twigs and the eggs hatch about 20 days later. The female actively tends her brood or colony, which can number from 15 to 50 individuals. Young nymphs have three horns instead of the one seen on the adults. While four generations occur per year, females lay only a single clutch of eggs.

Cosmic Couple


Cosmic Couple
Here we see the spectacular cosmic pairing of the star Hen 2-427 — more commonly known as WR 124 — and the nebula M1-67 which surrounds it. Both objects, captured here by the NASA/ESA Hubble Space Telescope are found in the constellation of Sagittarius and lie 15,000 light-years away.

The star Hen 2-427 shines brightly at the very center of this explosive image and around the hot clumps of surrounding gas that are being ejected into space at over 93,210 miles (150,000 km) per hour.

Hen 2-427 is a Wolf–Rayet star, named after the astronomers Charles Wolf and Georges Rayet. Wolf–Rayet are super-hot stars characterized by a fierce ejection of mass.

The nebula M1-67 is estimated to be no more than 10,000 years old — just a baby in astronomical terms — but what a beautiful and magnificent sight it makes.

Launching Galileo


Launching Galileo
The next two satellites in Europe's Galileo satellite navigation system will be launched together on 11 September, taking its orbital constellation a step closer to initial services.
Galileo is the global navigation satellite system (GNSS) that is currently being created by the EU & ESA. The project is named after the Italian astronomer Galileo Galilei. One of the aims of Galileo is to provide an indigenous alternative high-precision positioning system upon which European nations can rely, independently from the Russian GLONASS and US GPS systems, in case they were disabled by their operators.

Frog Love


Frog Love
Sometimes humans make a choice that seems to make no sense at all when it comes to love...but hey, we are not the only ones ;)
In a recent experiment, when female tungara frogs had a choice between two males, they chose the one with the best call. But, when a third frog with a clearly inferior call was introduced to the mix, the females chose the frog with the second best call. This strange phenomenon is known as the decoy effect.

Puppis A Supernova Remnant


Puppis A Supernova Remnant 
Driven by the explosion of a massive star, supernova remnant Puppis A is blasting into the surrounding interstellar medium about 7,000 light-years away. At that distance, this colorful telescopic field based on broadband and narrowband optical image data is about 60 light-years across.

As the supernova remnant expands into its clumpy, non-uniform surroundings, shocked filaments of oxygen atoms glow in green-blue hues. Hydrogen and nitrogen are in red. Light from the initial supernova itself, triggered by the collapse of the massive star's core, would have reached Earth about 3,700 years ago.

The Puppis A remnant is actually seen through outlying emission from the closer but more ancient Vela supernova remnant, near the crowded plane of our Milky Way galaxy. Still glowing across the electromagnetic spectrum Puppis A remains one of the brightest sources in the X-ray sky.

The voice in your head


The voice in your head
Do you have a little voice in your head?
If your mind said yes, then you’ll be interested to know that science is getting closer to understanding where it comes from.

“Psychologists have a long history when it comes to studying the inner voice. Russian psychologist Lev Vygotsky suggested back in the 1930s that our internal monologue was tied to our ability to speak aloud. And the technique of electromyography, which measures muscle movement, shows that our larynx is actually active during inner speech."

But it’s more recent research that’s getting us closer to understanding where the internal monologue really comes from. Neuroimaging testing performed in the 1990s demonstrated that parts of Broca’s area - the region of the brain responsible for speech - are also active when our inner voice is speaking to us. 

Either way, it’s just weird, though since we all do it to some degree it seems normal, right?

Try this, in your mind ask the question:  “Who is hearing this..” 

You might find that when you ask yourself that you’ll naturally answer, “I am.”
Well then, what’s hearing your answer? You’ll find there is no primary “listener.” Or maybe their is?

Which sleep position is healthiest?
Sleeping in the lateral, or side position, as compared to sleeping on one’s back or stomach, may more effectively remove brain waste and prove to be an important practice to help reduce the chances of developing Alzheimer’s, Parkinson’s and other neurological diseases, according to researchers at Stony Brook University.

Glass 3D printing (or G3DP) is based on a dual-heated chamber concept, with the top chamber heating the glass and lower chamber slowly cooling it to prevent internal stresses. The top chamber operates at approximately 1900°F, and funnels the molten material through an alumina-zircon-silica nozzle into its programmable shapes.

Mediated Matter group at the MIT Media Lab and the MIT Glass Lab collaborated on the development of 3D printing glass objects. They produced a printer that uses molten glass to create intricate glass vessels. Not only the objects are beautiful but the printing process itself is also amazing.

Stephen Hawking may have just solved one of the most vexing mysteries in physics — the "information paradox."
Einstein's theory of general relativity predicts that the physical information about material gobbled up by a black hole is destroyed, but the laws of quantum mechanics stipulate that information is eternal. Therein lies the paradox.

Hawking — working with Malcolm Perry, of the University of Cambridge in England, and Harvard University's Andrew Stromberg — has come up with a possible solution: The quantum-mechanical information about infalling particles doesn't actually make it inside the black hole.

Perseid meteor shower over Mt. Rainier, Washington


Perseid meteor shower over Mt. Rainier, Washington 
The image was created from a two-hour time lapse video, snaring over 20 meteors, including one that brightened dramatically on the image left. Although each meteor train typically lasts less than a second, the camera was able to capture their color progressions as they disintegrated in the Earth's atmosphere.

Here an initial green tint may be indicative of small amounts of glowing magnesium atoms that were knocked off the meteor by atoms in the Earth's atmosphere. To cap things off, the central band of our Milky Way Galaxy was simultaneously photographed rising straight up behind the snow-covered peak of Mt. Rainier. Another good meteor shower is expected in mid-November when debris from a different comet intersects Earth as the Leonids.

Dione
What's happening in this strange juxtaposition of moon and planet? First and foremost, Saturn's moon Dione was captured here in a dramatic panorama by the robotic Cassini spacecraft currently orbiting the giant planet. The bright and cratered moon itself spans about 1100-km, with the large multi-ringed crater Evander visible on the lower right.

Since the rings of Saturn are seen here nearly edge-on, they are directly visible only as a thin horizontal line that passes behind Dione. Arcing across the bottom of the image, however, are shadows of Saturn's rings, showing some of the rich texture that could not be seen directly. In the background, few cloud features are visible on Saturn.

The First Flexible Urinary Catheter


The First Flexible Urinary Catheter
Benjamin Franklin is credited with many inventions; the glass armonica, bifocals, the lightning rod, and many others.  However there is one invention that is truly forgotten to people today; the first flexible urinary catheter.  Today catheters are a staple of modern medicine, and the invention of the urinary catheter goes back thousands of years.  However catheters up to the 19th century were made of hard materials such as metal, and had no flexibility.

Such was the great misfortunate for John Franklin, Benjamin Franklin’s brother, who suffered from an inoperable kidney stone and had to cath daily with a hard metal catheter daily in order relief his bladder.  While Ben was known for his work with electricity, he was also interested in the fields of health and medicine.  He had studied anatomy in England, even taking part in vivisections within his own home. Thus in 1752 he put his mind into designing a better catheter for his brother.  Made from an extra soft silver alloy, the catheter was made of several dozen small flexible segments, held rigid by a stylet, and with holes bored into the sides for drainage.

Franklin had the catheter produced by a local silversmith, then sent to his brother in Boston with a letter stating, “It is as flexible as would be expected in a thing of the kind, and I imagine will readily comply with the turns of the passage”

Researchers use solar power to make carbon fiber out of thin air


Researchers use solar power to make carbon fiber out of thin air
I read yesterday this article, which made me wonder if  will reverse climate change. Interesting ideas bouncing in my cranial vault ;)

Carbon capture is an idea that’s been around for a while, but it’s always seemed like a bit of an afterthought, a way to slightly slow the pace at which we’re pumping carbon dioxide into the atmosphere. But what if we could do at a scale that would suck all the carbon we’ve emitted since the industrial revolution right out out of the atmosphere, and turn it into something incredibly useful?

This is the claim being made by Stuart Licht, a professor of chemistry at George Washington University, who earlier this month published a paper in Nano Letters demonstrating a method of turning atmospheric carbon dioxide into solid carbon using concentrated solar power, with only oxygen as the byproduct. The process, called Solar Thermal Electrochemical Photo (STEP) carbon capture, is highly efficient, as it uses both the visible light and heat of the concentrated solar radiation..

Messier 27 (M27) is an excellent example of a gaseous emission nebula created as a sun-like star runs out of nuclear fuel in its core. The nebula forms as the star's outer layers are expelled into space, with a visible glow generated by atoms excited by the dying star's intense but invisible ultraviolet light

Known by the popular name of the Dumbbell Nebula, the beautifully symmetric interstellar gas cloud is over 2.5 light-years across and about 1,200 light-years away in the constellation Vulpecula. This impressive color composite highlights details within the well-studied central region and fainter, seldom imaged features in the nebula's outer halo. It incorporates broad and narrowband images recorded using filters sensitive to emission from sulfur, hydrogen and oxygen atoms.

North American researchers at UC Berkeley and California Academy of Sciences have found that the larger Pacific-striped octopus has a unique hunting strategy: Rather than pounce on its prey, it stalks and gently taps it to startle it. Often this drives it into the octopus’s waiting arms…. 

The larger Pacific striped octopus , is, despite its name, no bigger than a tangerine.  Also uses a “slow bounce” to hunt. With its body flattened, and dorsal arms reaching forward, the octopus glides with sporadic bursts of hopping movements before it snatches up its prey of choice.

The Tree of 40 Fruit is an ongoing series of hybridized fruit trees by contemporary artist Sam Van Aken.


The Tree of 40 Fruit is an ongoing series of hybridized fruit trees by contemporary artist Sam Van Aken. Each unique Tree of 40 Fruit grows over forty different types of stone fruit including peaches, plums, apricots, nectarines, cherries, and almonds.

Sculpted through the process of grafting, the Tree of 40 Fruit blossom in variegated tones of pink, crimson and white in spring, and in summer bear a multitude of fruit. Primarily composed of native and antique varieties the Tree of 40 Fruit are a form of conversation, preserving heirloom stone fruit varieties that are not commercially produced or available.

What is grafting?
Grafting involves collecting young shoots or cuttings from trees and then inserting these budding branches into strategic points on a base tree.
These grafts are taped into place and allowed to bond with the tree, drawing water and nutrients from it like any other branch. If the grafts take to the tree, they'll start to grow again in the spring.

What is the Oort Cloud?


What is the Oort Cloud?
The Oort Cloud is a theoretical spherical cloud of predominantly icy planetesimals that is believed to surround the Sun at a distance of up to around 100,000 AU (2 ly). This places it in interstellar space, beyond the Sun’s Heliosphere where it defines the cosmological boundary between the Solar System and the region of the Sun’s gravitational dominance.

Like the Kuiper Belt and the Scattered Disc, the Oort Cloud is a reservoirs of trans-Neptunian objects, though it is over a thousands times more distant from our Sun as these other two. The idea of a cloud of icy infinitesimals was first proposed in 1932 by Estonian astronomer Ernst Öpik, who postulated that long-period comets originated in an orbiting cloud at the outermost edge of the Solar System.

Thanks for the interesting reading :)

Pseudocolochirus axiologus


Pseudocolochirus axiologus
Pseudocolochirus axiologus is a sea apple, a colorful and somewhat round sea cucumber. They can be found primarily in Indo-Pacific waters. Sea apples are filter feeders with tentacles, ovate bodies, and tube-like feet. They can release their internal organs or a toxin into the water when stressed. The sea apple feeds primarily on plankton, which it filters from the water with its tentacles. It alternately brings each tentacle to its mouth, scraping off the captured plankton.
