UV light reveals hidden colors in ancient shells



UV light revealed the way ancient shells looked millions of years ago.


Excerpt from perfscience.com


Using ultra-violet (UV) light, scientists have revealed astonishing colors of about 30 ancient seashells. According to PLOS, the seashells, which are estimated to be between 6.6 and 4.8 million years old, were looking white in regular white light. The true colors of the shells appeared in UV light.




According to the researchers, “The biology of modern Conidae (cone snails)-which includes the hyperdiverse genus Conus-has been intensively studied, but the fossil record of the clade remains poorly understood, particularly within an evolutionary framework”.

In the presence of UV light, the organic matter remaining in the shells fluoresces. With this, the shells appeared similar to what they looked when living creatures used to live in them. It is yet unclear which particular compounds in the shells are releasing the light when exposed to UV rays. With the help of the technique, the researchers were able to document the coloration patterns of 28 different cone shell species found in the Dominican Republic. Out of these 28 shells, 13 were found to be the species, which were not known earlier. And this could help know about the relationship between modern species.

San Jose State University geologist Jonathan Hendricks exposed over 350 fossil specimens to ultraviolet light. 

The coloration patterns of the ancient species were compared with existing animals and doing this, researchers found many displayed similarities. According to this finding, some modern species emerge from lineages. These lineages began in the Caribbean millions of years ago.

The newly distinguished species, Conus carlottae, was also among the newly distinguished species and it has a polka-dotted shell, which is not found in modern cone snails today. Researchers are now using UV light to emit color from porcelain white seashell fossils.

What our ancient ancestors found beautiful 50,000 years ago






Excerpt from news.discovery.com

The geode (above), described in the latest issue of Comptes Rendus Palevol, was found in the Cioarei-Boroşteni Cave, Romania. A Neanderthal had painted it with ochre.

"The Neanderthal man must have certainly attached an aesthetic importance to it, while its having been painted with ochre was an addition meant to confer symbolic value," said Marin Cârciumaru of Valahia University and colleagues.

The researchers also noted that "the geode was undoubtedly introduced into the cave by the Neanderthal," since they ruled out that it could have originated in the cave itself.

Was the geode used in rituals, or was it just a treasured object of beauty? Its precise meaning to the Neanderthal remains a mystery for now.




Based on archaeological finds, necklaces made out of Spondylus (a spiky, colorful mollusk) were all the rage. (Above)

This specimen has more of a reddish hue, but Michel Louis Séfériadès of CNRS notes that most are "a highly colored, very attractive purplish crimson." Séfériadès added that the shells were valued, early trade items and that they are now "found in the archaeological remains of settlements and cemeteries, in graves, and as isolated finds."

Some of the shells were made into jewelry, including necklaces and bracelets.

 

We sing about "five gold rings," but the rings would more likely have been ivory back in the day -- as in around 50,000 years ago, before ivory-producing animals were mostly hunted to extinction.
Early humans in northern regions, for example, made rings out of mammoth ivory. A Neanderthal site at Grotte du Renne, France yielded a carefully crafted ivory ring (above), as well as grooved and perforated "personal ornaments," according to archaeologist Paul Mellars of Cambridge University.



Charcoal (shown avove), ochre and other materials were applied to the face by early Homo sapiens as well as by other human subspecies. 

The ochre, used to paint the geode, mentioned earlier, was also used as makeup, hair dye, paint (to create rock and cave art), as well as to color garments.


Early humans used combs made out of shells and fish bones to both comb their hair and as personal decoration. (Above)

The shell from the Venus comb murex, a large predatory sea snail, is just one species that seems perfect for this purpose. Gibraltar Museum researchers Clive Finlayson and Kimberley Brown also found evidence that Neanderthals valued large, elaborate feathers, which the scientists suspect were worn by the individuals. 

Nearly all early cultures had coveted figurines holding probable symbolic value. Some of the earliest carved objects are known as "Venus" figurines. They present women with exaggerated sexual features. Their exact meaning remains unclear. (Above)

Pendants made of animal teeth were common and probably served many different functions, such as showing the hunter's success, offering symbolic protection, and just as fashion. 

Some of the funkiest-looking teeth were made into worn objects.
Animal teeth could be on a gift list dated to 540,000 years ago, and possibly earlier, as a recent study in the journal Nature found that a population of Homo erectus at Java, Indonesia, was collecting shark teeth and using them as tools and possibly as ornamentation.

 

The world's oldest known musical instrument is a bone flute (Above). While the earliest excavated flute dates to about 42,000 years ago, comparable flutes were probably made much earlier.

Flutes, like most of the items on this list, were not essential to survival, but yet they somehow contributed to the prehistoric peoples' quality of life.

Excerpt from foxnews.com/science


A rare planet has been discovered, and it doesn’t seem like a stop anyone would want to make on an intergalactic cruise. Found by two research teams independently of each other, Kepler-432b is extreme in its mass, density, and weather. Roughly the same size of Jupiter, the planet is also doomed- in 200 million years it will be consumed by its sun. “Kepler-432b is definitively a rarity among exoplanets around giant stars: it is a close-in gas-giant planet orbiting a star whose radius is 'quickly' increasing,” Davide Gandolfi, from the Landessternwarte Koenigstuhl (part of the Centre for Astronomy of the University of Heidelberg), told FoxNews.com. “The orbit of the planet has a radius of about 45 million kilometers [28 million miles] (as a reference point, the Earth-Sun distance is about 150 million kilometers [93.2 Million miles]), while most of the planets known to orbit giant stars have wider orbits. The stellar radius is already 3 million kilometers [almost 2 million miles] (i.e., about 4 times the Sun radius) and in less than 200 million years it will be large enough for the star to swallow up its planet.”

Gandolfi, a member of one of the research groups who discovered the rare planet, explains that much like Jupiter, Kepler-432b is a gas-giant celestial body composed mostly of hydrogen and helium, and is most likely to have a dense core that accounts for 6 percent or less of the planet’s mass. “The planet has a mass six times that of Jupiter, but is about the same size!” he says. “This means that it is not one of the largest planets yet discovered: it is one of the most massive!” The planet’s orbit brings it extremely close to its host star on some occasions, and very far away at others, which creates extreme seasonal changes. In its year - which lasts 52 Earth days - winters can get a little chilly and summers a bit balmy, to say the least. According to Gandolfi, “The highly eccentric orbit brings Kepler-432b at ‘only’ 24 million kilometers [15 million miles] from its host star, before taking it to about three times as far away. This creates large temperature excursions over the course of the planet year, which is of only 52 Earth days. During the winter season, the temperature on Kepler-432b drops down to 500 degrees Celsius [932 degrees Fahrenheit], whereas in summer it can goes up to nearly 1000 degrees Celsius [1832 degrees Fahrenheit].”

Then again, if you are crazy enough to visit Kepler-432b, you’d better do it fast. As stated before, its host star is set to swallow the planet whole in 200 million years, making the celestial body a rare find. “The paucity of close-in planets around giant stars is likely to be due to the fact that these planets have been already swallowed up by their host stars,” Gandolfi says. “Kepler-432b has been discovered ‘just in time before dinner!” The host star, which is red and possesses 1.35 times the mass of our sun, has partly exhausted the nuclear fuel in its core, and is slowly expanding, eventually growing large enough to swallow Kepler-432b. According to Gandolfi, this is a natural progression for all stars. “Stars first generate nuclear energy in their core via the fusion of Hydrogen into Helium,” he explained. “At this stage, their radii basically do not change much. This is because the outward thermal pressure produced by the nuclear fusion in the core is balanced by the inward pressure of gravitational collapse from the overlying layers. In other words, the nuclear power is the star pillar! Our Sun is currently ‘burning’ hydrogen in its core (please note that I used quotes: ‘burning’ does not mean a chemical reaction- we are talking about nuclear fusion reaction). However, this equilibrium between the two pressures does not last forever. Helium is heavier than hydrogen and tends to sink. The stellar core of the Kepler-432b's host star is currently depleted of hydrogen and it is mainly made of inert helium. The star generates thermal energy in a shell around the core through the nuclear fusion of hydrogen into helium. As a result of this, the star expands and cools down. This is why we call it ‘red giant’- the reddish color comes from the fact that the external layers of the atmosphere of the star are cooling down because they expand.”

Both research teams (the other was from the Max Planck Institute for Astronomy in Heidelberg) used Calar Alto Observatory’s 7.2- foot telescope in Andalucia, Spain. The planet was also studied by Landessternwarte Koenigstuhl researchers using the 8.5-foot Nordic Optical Telescope on La Palma, which is located in Spain’s Canary Islands.

Google to lease former Nasa airfield for space research


Hangar One
Google will restore Hangar One which has become a landmark in Silicon Valley

Excerpt from

bbc.com



Google latest "moonshot" is an apt one - it is investing in a Nasa-owned airfield to expand research into space exploration and robotics.

Planetary Ventures, an offshoot of Google, will take over management of the Moffett Federal Airfield.

The airfield is already regularly used as a landing strip for the private jets of the firm's billionaire executives.

Google has not divulged exactly how the site will be used.
But, according to a Nasa press release, the site will be used for "research, development, assembly and testing in the areas of space exploration, aviation, rover/robotics and other emerging technologies".

For Nasa, the sale offers rich pickings - the agreement will provide it with $1.16bn (£731m) in rent over the initial 60-year lease term.

"As Nasa expands its presence in space, we are making strides to reduce our footprint here on Earth," said Nasa administrator Charles Bolden. 

And for Google, the investment represents an opportunity to restore an iconic building.

Part of the deal includes the restoration of Hangar One, an important landmark in Silicon Valley. Built in 1933, it is one of the world's largest free-standing structures.


Moffett Federal Airfield golf courseThere is also a golf course on the site


Planetary Ventures plans to invest more than $200m in rebuilding Hangar One and two other hangars on the site.

It will create an educational facility where the public can explore the site's legacy and the role of technology on it.


Very little is known about Planetary Ventures, the firm behind the deal. Press reports describe it as shell organisation for real estate deals although the name hints at something more. 

The base, previously maintained by Nasa's Ames Research Center, is located four miles from Google's Mountain View headquarters.


Space Projects

It is not the first time Google has invested in unusual purchases. Two mysterious barges that appeared on the coasts of San Francisco and Portland, Maine, last year turned out to be Google-owned.

It emerged that Google intended to use them as floating showcases for new products such as Google Glass and its self-driving cars. The project was later abandoned after coastguard officials deemed them to be a fire risk.

(It is not) the first time that Google has worked with Nasa. Back in 2005, Google built an office at Nasa's research facility in order to co-operate on a range of projects.

More recently, the two teamed up to launch a new laboratory, focused on advancing machine learning, also based at Nasa's research centre.

Has Amelia Earhart’s plane finally been found? Not so fast


 


Excerpt from

A small group of wreckage hunters purports to have found a bit of Earhart’s Lockheed Electra aircraft. It’s a good story, but critics of the find are more vocal than ever.


A metal sheet, some small bones and an “ointment pot” may be the final artifacts of Amelia Earhart’s failed 1937 journey around the world, if a small group of wreckage hunters is to be believed. They could also be the remains of some other plane, a turtle and trash. 

But the International Group for Historic Aircraft Recovery (Tighar), which first found the warped bit of aluminum on a 1991 trip to the tiny atoll of Nikumaroro, in the Republic of Kiribati, says the 19in-by-23in slab has to be part of Earhart’s Lockheed Electra aircraft, which disappeared while she was flying over the Pacific. 

Tighar’s executive director Ric Gillespie made headlines this week by announcing “new research” into the 1991 fragment that he says answers earlier critics and proves it is from Earhart’s plane. 

The story he proposes is not implausible: the metal’s rivets don’t match with the Electra’s design, but that’s because because it’s actually a patch made to repair the aircraft after a bad landing in Miami, earlier on Earhart’s trip. Gillespie’s team managed to find a Miami Herald photo from 1937 which shows, over the place where a window should be, a particularly shiny piece of metal. In fact, a lab tested the metal back in 1996 and found it to be “essentially the same” 24ST Alclad aluminum that was to cover most aircraft of the 30s, including Earhart’s Electra. Gillespie says that “the patch was as unique to her particular aircraft as a fingerprint is to an individual … [the aluminum] matches that fingerprint in many respects”.

Under Gillespie’s theory, Earhart made it to the island, sent radio signals “for at least five nights before the Electra was washed into the ocean”, and eventually died there.

But Gillsepie’s been here before, and his critics are not quiet, with one saying: “Everybody should have facts to back up [their] opinions, and Mr Gillespie, well, he doesn’t.” (A second, more concisely, says: “He’s very creative.”) After discovering the metal, Gillespie gave a 1992 press conference to say that “every possibility has been checked, every alternative eliminated … We found a piece of Amelia Earhart’s aircraft.”

Objectors immediately pointed out that he had not checked the fragment’s rivets, which did not match Earhart’s Electra. Now, 22 years later, the photo could indeed explain the discrepancy – but Gillespie still lacks a wreck to compare the pattern to. As a substitute, Gillespie’s team went to a Kansas facility that’s restoring an Electra and claims to have found – by holding the patch up alongside the restored plane – that the rivets seemed consistent with the pattern. No independent researchers have confirmed their findings.

To be fair, Tighar realizes they know less about the scrap than they’d like: “If the artifact is not the scab patch from NR16020, then it is a random piece of aircraft wreckage from some unknown type involved in an unknown accident that just happens to match the dozens of material and dimensional requirements of the patch.”

Considering the vastness of the Pacific Ocean and the sheer amount of wreckage scattered across it over the past century, this actually seems pretty reasonable, but Tighar doubles down on its implication of certainty: “[That would mean] this incredibly specific, but random, piece of debris just happened to end up on Nikumaroro, the atoll where so much other evidence points to Earhart.”

What evidence does Tighar present? In 2011 they tested three bones found near a turtle shell, which could perhaps have been human or that of a turtle. DNA tests were inconclusive. (Gillespie says “the door is still open for it to be a human finger bone.”)

Gillespie told the Miami Herald earlier this year that “the key to it is her final message, where she says ‘line of position 157 dash 337’ … That’s a line that Noonan calculated from the sunrise, running 337 degrees to the north-west and 157 degrees to the south-east. And if you follow it far enough, there are two deserted islands on it, McKeon Island and Gardner Island.” 

It’s a good story, just like the one ex-marine Floyd Kilts used to tell about how a tribesman told him about a partial human skeleton and a woman’s shoe, which ended up with a British official and disappeared afterward. (Micronesians settled on the island a year after Earhart vanished.) But despite all the story and circumstantial evidence, no expedition in the past 70 years has found the Electra on or near either island.

But Tighar of course thinks it might. It found a “sonar streak” 600ft below the surface “the right size, the right shape … in the right place to be part of the Electra”, which the group has so far had neither the time nor funding to investigate. Gillespie admits it could also be part of a reef, a geological formation or any number of things once lodged into the seabed and now drifted away. He intends to explore the site in a 2015 expedition. Whether he turns up with Earhart’s lost Electra or something else entirely, he will have a new story.
