An ancient brown dwarf is the most massive and purest such "failed star" ever discovered, a new study suggests.
Researchers studied an object called SDSS J0104+1535, which lies about 750 light-years from Earth in the Milky Way's "halo," a population of extremely old stars above the galaxy's familiar spiral disk.

SDSS J0104+1535 is a brown dwarf — a bizarre, gaseous body larger than a planet but too small to sustain the nuclear fusion reactions that power stars. New observations by the European Southern Observatory's Very Large Telescope in Chile provide new details about this object, which astronomers think is 10 billion years old. [The Strangest Things in Space]

For example, study team members said, SDSS J0104+1535 is about 90 times more massive than Jupiter, making it the heaviest known brown dwarf. (For perspective: The sun is 1,050 times more massive than Jupiter. And Jupiter is 318 times more massive than Earth.)
In addition, just 0.01 percent of SDSS J0104+1535 consists of elements other than hydrogen and helium — meaning that the body is 250 times purer than the sun, and the purest brown dwarf ever observed.

"Pure" in this sense refers to the stuff originally present just after the Big Bang that created the universe 13.82 billion years ago — mostly hydrogen and helium, along with small amounts of lithium. All the naturally occurring elements heavier than these three were created inside stars over the eons.
"We really didn't expect to see brown dwarfs that are this pure," study lead author ZengHua Zhang, of the Institute of Astrophysics in the Canary Islands, said in a statement. "Having found one, though, often suggests a much larger hitherto undiscovered population. I'd be very surprised if there aren't many more similar objects out there waiting to be found."
The new study has been accepted for publication in the journal Monthly Notices of the Royal Astronomical Society. You can read it for free at the online preprint site arXiv.org.

Rugged Antarctica Shows Its Ice in New 3D Map



Scientists have created a 3D view of Antarctica by combining 250 million measurements taken by the European Space Agency's CryoSat mission between 2010 and 2016.

A new three-dimensional view of Antarctica shows off the southernmost continent in all of its rugged glory.
Created by satellite data collected by the European Space Agency's CryoSat, the map can be downloaded at a University of Leeds websiteand will soon be hosted at the portal for the United Kingdom's Center for Polar Observation and Modelling (CPOM).

"We used around 250 million measurements taken by CryoSat between 2010 and 2016 to create the most comprehensive picture of Antarctic ice elevation currently available," Tom Slater, a researcher at the center,said in a statement

CryoSat uses radar altimeter to measure ice-sheet thickness at the North and South Poles. This method involves beaming radio waves toward the ground from a satellite and measuring the time it takes for the reflected waves to bounce back. The instrument aboard the CryoSat satellite is the first of its kind designed for monitoring ice, according to the ESA; it can also measure sea level. [Images of Melt: Earth's Vanishing Ice]

The measurements are useful to scientists who are trying to understand changes in the Antarctic ice sheet, including where increased snowfall is causing accumulating ice and where melting and iceberg calving are causing ice losses.
"This should benefit not only studies of the Antarctic ice sheet, but also projections of future sea-level rise," Andrew Shepherd, the director of CPOM, said in a statement.
As the climate warms, Antarctica's ice is changing. In 2002, the Larsen B ice shelf collapsed spectacularly, and a massive rift in the Larsen C ice shelf is threatening to do the same to that floating ice. When floating ice shelves collapse, they do not raise sea levels by themselves, but their loss does remove a barrier to the flow of land-based ice into the oceans.
Scientists have observed a trend toward melting on the land-based West Antarctica ice sheet in recent years, according to the National Snow and Ice Data Center. The data from East Antarctica has been trickier to interpret, with some research finding that the region was adding ice because of increased snowfall. (Warm air can hold more moisture, so as the globe warms, precipitation might increase in some areas.) Because of the balancing act between ice loss in the west and ice gains in the east, there has been a long-running scientific controversy over whether the continent as a whole is losing or gaining ice.
Alarmingly, field scientists recently discovered huge craters called moulins on East Antarctica's Roi Baudouin ice shelf. The melt features had never been seen before on an ice shelf. Research published in the journal Nature Climate Change in December 2016 on the moulins and new satellite data found that East Antartica may be more vulnerable to melt than previously believed.

130-MPH Spring-Loaded Jaws Help These Ants Escape Predators

TRAP-JAW ANTS HAVE an astounding weapon: their mouth. Their spring-stacked jaws are equipped for snapping close as quick as 60 meters/second (134 miles/hr) and can create strengths more than 300 times their body weight. These ants are brutal predators of termites and other little creepy crawlies with their deadly jaw snap. Trap-jaw ants likewise can launch themselves into the air with a jaw snap:

This trap-jaw subterranean insect strikes at an obstruction, throwing itself in reverse over its mates. Adjusted FROM PATAK LAB VIDEO, DUKE UNIVERSITY

Beside being truly perfect to watch, why may ants that are so considerably ensured with intense jaws use them in such a peculiar way? Is it only a side effect of strong jaws that they every so often send themselves flying ass over teakettle?

Jaws that snap close with amazing power can have both a hostile and guarded capacity. The jaws can hurl an adversary away amid a battle; and when under assault, a settlement of ants excursion themselves around like popping popcorn, bewildering assailants.

New research took a gander at how the jaws may work against a predator of ants: antlions. Antlions are, as you may surmise from the name, a sort of bug that preys upon ants. Antlions construct dens in the sand and sit tight for a subterranean insect or another creepy crawly to tumble in. The antlion gets its casualty with huge, threatening jaws, pulls it under the sand, and infuses digestive liquids into the prey's body pit.

In the event that you think this sounds a touch like a Star Wars saarlac, a Tremors graboid, or the Ceti eel that got put into Chekov's ear, you aren't off-base. Those were propelled by antlions. It is a commendable enemy for a trap-jaw subterranean insect.

Antlions excursion grains of sand at their casualties to make their pit dividers less steady, and rush their slide to fate:
antlion pit

Analysts Fred Larabee and Andy Suarez thought about whether ants' trap-jaw could help guard against antlions. To figure out, they dropped a group of ants onto a pack of antlions, and watched what happened. This sounds a touch like what an inquisitive child may do, yet with controls and fast feature archiving it, it's likewise science.

To start with the scientists reaped antlions, and let them set up their entanglement traps in the lab. At that point they included trap-jaw ants close to the pits. About a large portion of the time the ants had the capacity fled from the antlion and out of the pit. 36% of the ants were eaten. In any case, 15% of the ants utilized their jaws to launch themselves out of the pit in the wake of experiencing the antlion.

To verify that the jaws were basic to the ants' escape, the specialists stuck the ants' jaws close, and contrasted survival and without working mandibles. Ants with in place (untreated) jaws got away at double the rate of ants with superglue props.

Trap-jaw ant mandibles were glued shut to prevent ants from snapping.

Presently we realize that in one types of trap-jaw subterranean insect, the jaws do have a cautious capacity. Be that as it may, trap-jaws have freely advanced numerous times in ants; and not in firmly related gatherings. Is the capacity to indulgence themselves into the air something that is a cheerful mischance of monster jaws, or is it likewise being followed up on by characteristic choice? Also, which started things out, the hostile or cautious capacity?

By measuring strike speed, power, and the settings of these practices in diverse subterranean insect species, specialists would like to astound out how these stunning structures advanced.

Here’s How Burners Can Prepare for the Bugpocalypse

One stinkbug (Family: Pentatomidae) that didn't go to Burning Man this year.

ON WEDNESDAY, SAN Francisco's schadenfreude meter went off the scale when the coordinators of Burning Man affirmed that their site—a desert patch outside of Gerlach, Nevada that they call Black Rock City—is being overwhelmed by bugs. The pictures out of the playa look scriptural, with misty layers of little dark bugs and bigger, level green ones covering tires and wood and rug.

A bit gross, yet not so much something to get blew a gasket about. Burners, all things considered, are about independence and being unified with nature and stuff. They ought to be totally ready to manage a little creepy crawly squall, isn't that so?

All things considered, possibly. It really may be harder than burners might suspect to exist together with their surrey bunkmates.

Here's the reason. After some entomological sleuthing in view of photographs shared by the burners, Gizmodo nailed down the family level of some of those bugs (the photographs so far haven't been nitty sufficiently gritty to get more particular than that). They're generally seed bugs in the family Miridae, Lygaeid bugs from the Genus Nysius, and stink bugs (Pentatomidae).

Those sorts of bugs, shockingly, are not the sort that you can avoid with conventional creepy crawly repellants. Mixes like DEET chip away at creepy crawlies that are searching for people for parasitic. Smells particular to warm blooded animals' body warmth pull in multi-legged vampires. DEET lives up to expectations by hindering the capacity of mosquitoes and ticks to discover people by homing in on CO2 and stinky human unpredictable chemicals.

The genuine bugs—that is, seed and stink bugs—are for the most part searching for plants and creepy crawlies they can drain the juice out of. While these bugs have allegedly been "gnawing" individuals and leaving welts, they can't in fact nibble anybody; they don't have jaws! They have just sucking mouthparts, so it's more right to say they jab you than nibble you. The "jab" is their reaction to being squashed in your garments, for the most part—the stink bugs, specifically, are sufficiently enormous to give you a jab that damages. Also, there are just so a considerable lot of the bugs that some of them can't resist the urge to wind up in a position to be pounded.

Presently, on the grounds that these aren't real parasitic, human-gnawing bugs, that implies customary creepy crawly repellants won't chip away at them. However, we're at Burning Man, man. Like, individuals wouldn't be utilizing that synthetic slop at any rate, correct? Simply use like, a home grown repellant.

In any case, hold up, no. Since these are plant-sucking creepy crawlies, you ought to be careful about natural cures that claim to repulse bugs. Since… .plants are what these fellows are pulled in to! (Schadenfreude alarm: Secretly, wouldn't it be wonderful if the thing these bugs were pulled in to the most was patchouli?)

Here's the genuine, entomologist-sanction arrangement: vacuum cleaners. A dustbuster could without much of a stretch suck every one of these suckers up, if a vacuum cleaner could be found at Burning Man. (Sun oriented fueled?). Obviously, your vacuum cleaner will stink subsequently.

To stay away from that, one trap is to secure pantyhose around the end of the spout with an elastic band, and stuff one of the legs into the vacuum hose. That keeps the bugs from going into the sack and stinking up your vac forever. When you suck up every one of the bugs, pull the underwear hose off and hitch it up. Bugs controlled and prepared for transfer.

The drawback, obviously, is that by doing anything to attempt to dispose of the bugs you're going to slaughter some of them. A percentage of the bugs would survive this jury-fixed vacuum gatherer, however numerous would squish. That is still superior to anything taking the exhortation of Burning Man's "Cobra Commander," cited in the first blog entry about the bugs saying that he trusts the bugs fade away naturally "in light of the fact that else we're gonna need to nuke the city" to dispose of them. As we have clarified before here at WIRED, executing things with flame is a loathsome thought.

We'll expect that was said jokingly—in light of the fact that what could be more contradictory to the entire Burning Man experience than shelling an entire populace out of presence? One of the occasion's managing standards is "Leave No Trace," and practically every burner views themselves as a naturalist.

Along these lines, yes, bug sprays will conflict with these fellows. Be that as it may, why might you go out into nature just to annihilate it? Truly, in the event that you need to return to nature, and there is real natu

Millipede Genitals, Now in Glorious 3-D!

The Visible Millipede: <iOmmatoiulus avatar. The orange parts are the naughty bits, helpful in distinguishing between species.
IT'S BLUE, ITS name is "symbol," and it's virtual. In any case, it's not a 10-foot-tall humanoid outsider; it's another millipede species, and the first to be a "cybertype." Ommatoiulus symbol is the first species to be portrayed utilizing high-determination X-beam microtomography (microCT) 3-D pictures as a major aspect of its authority taxonomic depiction.

The primary logical depiction of another species has an assigned "sort"; it's a physical example that fixes the name to an individual animal varieties. A large number of these examples are kept the world over in exhibition halls, every picked and connected to the first researchers that picked the species name. (Carl Linnaeus is the sort for Homo sapiens, for instance.) The creators named their new species symbol to perceive advanced representations of creatures as a major aspect of animal types sort portrayals.

3-D Millipede Genitals Are Strangely Fascinating

Those sort portrayals incorporate some really tremendous pictures of the millipede's garbage. Female millipede private parts are housed in a fixed, vulvular box. Guys use pointy, spiky gonopods ("sex legs") to jab that case transparent sperm into a female millipede's neck. Male millipede sex-tackle can be a touch of disturbing looking:
rotating male millipede bits
Invertebrate researchers concentrate on private parts not on account of they are pervs, but rather in light of the fact that sexual device is a solid approach to recognize species. A horrendous parcel of millipedes, bugs, and creepy crawlies have a striking resemblance: little, dim, heaps of legs. Provocative bits are restricted in which species contrast; choice to demoralize hookups in the middle of species and contending hobbies between the genders have made stunning species-particular structures. 

Having an order framework in view of the privates of little creatures has one downside: The squidgy bits are… .little. What's more, typically concealed away. 3-D volumetric imaging takes care of that issue, making excellent pictures that can be pivoted to discover only the right edge. For survey, that is. 

MicroCT pictures permit inner structures of millipedes (or different creatures) to be seen without needing to damagingly yank parts off or mutilate their course of action. A noteworthy danger of working with notable exhibition hall examples is harming them trying to look at inward structures. With volume rendering sweeps, gonads and related structures can be for all intents and purposes uprooted and shaded to make 3-D pictures. Far and away superior, when examples stay in place, a researcher is less inclined to lose their private parts. 

Um. The millipede privates. In any case, you realized that is the thing that I implied, correct? 

At any rate, this is what a female O. symbol millipede resembles; this cross segment shows musculature and other delicate tissues, notwithstanding eggs and genital structures. This example wasn't cut up; in the wake of filtering the she was saved in a historical center as a voucher, connecting the physical and virtual depiction in time and space. The advanced pictures made were additionally posted in Dryad, an on the web, open source information stor.Cross section of a female 0. avatar specimen.

How Do You Make 3-D Rotating Genitals?

I solicited one from the creators of the study, Brian Metscher, exactly how one goes about making pictures of this sort, and what it costs. He depicted the product utilized (Amira and Photoshop), as "doltish lavish." 

"The first picture information is produced using tomographic imaging utilizing a business lab-based microCT framework. One of those expenses upwards of a large portion of a million euros now, however there are somewhat more person on foot frameworks for closer to €225k [$262K US Dollars]. They are coming into more regular utilization by bigger organizations, and frequently one can finish examines as an administration for a couple of hundred for every outputfemale millipede

Is a Picture Worth a Thousand Words?

Craftsmanship and science have constantly voyage together in science; dazzling work of art has went with species depictions for a long time. Taxonomists rely on upon these delineations to make sense of what species they have close by. The keys utilized as advisers for sort things out are here and there angering; the depictions can be more befuddling than supportive. Practically every taxonomist I know accept this position at any rate once per day:
Eric Eaton
"It's especially rankling when you're attempting to control two or more modest blobs gliding in glycerin and by one means or another hold them at the same plot for examination and distinguishing proof," said Terry Wheeler, of McGill University's Lyman Entomological Museum. "A major in addition to [3-D microCT] is that you possibly have much better and pinpoint control over the point of perspective… the capacity to filter inside, also the wonderful level of subtle element, is extremely cool." 

"This is an extraordinary case of why scientific categorization isn't static; it's a perpetually developing train that progressions with each mechanical development… Images can be shared worldwide without the need (and innate threats and expense) to convey or mail … uncommon examples," Wheeler inc

News Flash: Flash Is Out of Date

Having the capacity to see inner life systems in such detail is splendid, and an exciting prospect to those of us who have battled with arcane taxonomic keys. Be that as it may, what will happen quite a while from now, when some future taxonomist needs to take a gander at some of these pictures? These astounding pivoting pictures made in 2013 are just are available from 1 of the three PCs I have entry to, and can't be seen at all on my telephone. 

Precious stone Maier, Insect Collection chief for the Field Museum, said "the genuine advancement is acknowledgment that the example is not simply the bug on the pin. It's the majority of the information that runs with it as well. We truly need to begin incorporating information care when we are considering the consideration of accumulations… It is a decent approach to raise the discussion of whether ICZN ought to represent the statement of related information (counting pictures, genomic information, and so on.) as it does with sort examples." 

ICZN, the International Commission on Zoological Nomenclature, represents every creature specie names and sort example stores. It is, basically, scientific categorization court. They make decisions on what names are substantial, and set principles about how one may assign and name new species. 

Presently, ICZN does not perceive "cybertypes." It's not a gathering known for fast change; there is still a considerable measure of contention about regardless of whether one ought to be permitted to portray another species in an online-just investigative diary. That is sensible, however, since they are curating 250 years of exploration, and an expected 3 billion examples in exhibition halls around the globe. 

Maier additionally let me know: "'cybertype' ought to in no way, shape or form supplant a genuine example saved in an accumulation… Whether it's genomic work, examining gut substance, or routines we haven't even imagined about yet, we have to verify that we are saving the examples because of future researche

Glowing Tampons Help Detect Sewage Leaks

Lerner sampling

"YOU DO GET individuals taking a gander at you peculiarly, however the tampon is not that self-evident."

That is Professor David Lerner, clarifying what it was similar to direct an examination venture where ladylike cleanliness items were embedded into streams and sewers around Yorkshire, UK. Why? It turns out tampons are a precise and shoddy approach to test water quality.

Towns and urban communities more often than not have two different sewer frameworks. A clean sewer gathers all that you flush or wash down the channel, and transports it to a sewage office for treatment. Storm sewers or flood sewers gather up downpour and spillover from rooftops, cleared streets, and parking areas. They purge that water into characteristic conduits like streams or waterways.

Storm sewers are not intended to handle untreated waste waters so it's vital to keep what goes into them clean. "Dark water" tainting is a typical issue — water from dishwashers, showers, and clothing that winds up in the tempest sewer by means of awkward pipes or intentional dumping.

Before you choose that dim wash water isn't that awful, as a FYI a wide range of non-stunning things live in your clothes washer: norovirus and rotavirus; human pathogenic organisms; and obviously a wide mixed bag of fecal microorganisms. Dishwashers are very little better.

Clothing water looks essentially like customary water. So by what method would you be able to tell if a stream is tainted? Restricted is to test for OBs, or Optical Brighteners (not to be mistaken for Obstetricians, or OB Brand tampons).

OBs are a consistent added substance to cleansers that light up whites and help conceal yellow stains. They do this with an astute bit of visual fraud — an option name for optical whiteners is fluorescent whiteners. These mixes retain imperceptible bright light and re-transmit it as unmistakable blue-white light, making your whites more white. In the event that you happen to have yellow stains on your shirt neckline, the blue spreads up the yellow by means of integral shading concealing.

Optical brighteners don't happen actually in waterways and streams, so they are a convenient marker for defilement from human dim water sources. Lighting up mixes sparkle brilliantly under UV light, so they're an unmistakable marker of contamination.

Fiber optic links can be embedded into sewer frameworks to screen defilement, however the expense is very high–up to 9 £ ($13) per meter of sewer tried. Spectrophotometers can be utilized to identify contaminants, yet they aren't shoddy, and oblige preparing and adjustment to utilize dependably. Testing a whole system of channels and sewers in an expansive urban region would be fantastically lavish in both time and gear.

What Lerner and his examination coconspirator needed was a straightforward, ease strategy for checking water tainting. Something that individuals from the general population could do to check their neighborhood streams. So the two Yorkshire engineers changed a US Environmental Protection Agency observing system utilizing cotton cushions to be considerably less difficult, littler, and more compact: they utilized tampons as ecological samp

Congress, Don’t Make Us Hitch Rides With Russia. Love, NASA

GettyImages-158781036
SATURDAY WILL MARK 1,500 days since the Space Shuttle touched down for the last time. Establishing human spaceflights was constantly expected to be transitory as we made the essential move to another era of rocket, worked by American business bearers. In like manner, paying for seats on Russian rocket to send our space explorers to the International Space Station (ISS) was constantly proposed to be a stopgap.

Had Congress satisfactorily financed President Obama's Commercial Crew proposition, we could have been making last arrangements this year to at the end of the day dispatch American space explorers to space from American soil on board American rocket.



Charles F. Bolden Jr. is the twelfth Administrator of the National Aeronautics & Space Administration (NASA). As a NASA space traveler he traveled to space four times on board the Space Shuttle. Bolden served for a long time in the U.S. Marine Corps, including 14 as an individual from NASA's Astronaut Office.

Rather we are confronted with instability—and we will keep on being inasmuch as Congress opposes completely putting resources into Commercial Crew.

What we do know for certain is that each dollar we put resources into Moscow is a dollar we're not putting resources into American organizations in Missouri, Michigan, Minnesota or any of the 35 states where 350 American organizations are attempting to permit the best nation on Earth to at the end of the day dispatch our own space explorers into space.

It's as though we continue requesting extravagant takeout on the grounds that we haven't yet set up our own kitchen—just, for this situation, the takeout dinners are costing us countless dollars. Just as of late, NASA was left with no other decision however to compose a $490 million check to our Russian partners so we can get our own space travelers to the Space Station. It doesn't need to be like this. Congress can ought to still settle this by putting resources into Commercial Crew.

Each dollar we put resources into Moscow is a dollar we're not putting resources into American organizations.

To see how we arrived, it merits returning to our late history: The Space Shuttle had a 30 year keep running like none other. Four times I was honored with the chance to go to space on board this brilliant shuttle. There has never been a vehicle very like it: a reusable rocket, with the excellence of a plane, the ability to convey eight space travelers to space and a 60-foot payload straight. The Shuttle's three-decade long run was out and out striking.

As WIRED's perusers know well, innovation advances after some time. The Shuttle's first orbital spaceflight—STS 1—was propelled on April 12, 1981. After four months, on August 12, 1981, the first IBM PC was presented and it would, as WIRED's Christina Bonnington composed, "… at last change individuals' feelings of PCs and goad their reception. It is hard to exaggerate [its] part." STS-1 had a comparable impact on human spaceflight. As noteworthy similar to the first IBM PC or the first Macintosh (discharged a couple of years after the fact, in 1984), today's cutting edge applications and difficulties call for more up to date advances and gadgets. The same can be said for spaceflight.

As we try to send our space explorers more remote into profound space than any time in recent memory before—as far, actually, as a space rock set in lunar circle in the 2020s and Mars in the 2030s—we have to manufacture another era of shuttle.

In 2004, President Bush made the exceptionally troublesome choice to resign the Space Shuttle after a mind blowing run. In spite of the fact that this was not a simple choice, it was the right one: It was the suggestion of the board examining the loss of Space Shuttle Columbia and it was embraced by numerous individuals in the space group, including myself. In any case, it was not intended to be a definite choice.

From his first days in office, President Obama made it a need to return human spaceflight to American soil. Five years prior, talking at the Kennedy Space Center in Cape Canaveral, Florida, he laid out a visionary methodology for space investigation in the 21st century. The centerpiece of this technique was a Journey to Mars that would reach a state of perfection with sending American space travelers to the Red Planet in the 2030s.

To finish this Journey to Mars, the President requested that NASA further its work on a rocket and dispatch a framework that would effectively bring our space explorers into profound space. Today, that shuttle, Orion, has had an effective (uncrewed) flight into profound space and that dispatch framework, the Space Launch System (SLS) is over and over passing real turning points.

While NASA concentrated on the most proficient method to get our space travelers to profound space, the President's arrangement called for us to work with business accomplices to keep on getting our space explorers and freight to the International Space Station. Doing as such would be a "two-fer" in that it would permit NASA to concentrate on profound space, while enabling American business people and pioneers to fabricate another business market in low-earth circle. The arrangement was called Commercial Crew.

Notwithstanding the significant monetary advantages of Commercial Crew, there is additionally an in number financial case to be made. On a for every seat premise, it costs more or less $81 million to send an American space traveler to the Space Station on the Russian Soyuz shuttle. By correlation, it will cost $58 million for each seat to send our space travelers to the Space Station on Boeing's and SpaceX's shuttles, once they are ensured.

Indeed, even with every one of these advantages, Congress has reliably underfunded the sum asked for by the President for NASA's project to return dispatches of American space travelers to the Kennedy Space Center. Since 2010, the President has gotten give or take $1 billion short of what he asked for NASA's Commercial Crew activity. Amid this time we've sent $1 billion to Russia.

Space travel is unpredictable, yet this decision is basic: Do we put resources into ourselves—in our organizations, our inventiveness, our kin—or do we pick rather to send our assessment dollars to Russia?

We are the nation that kissed the moon. We're the nation that is wandering Mars. We're the nation that keeps on coming to new skylines, including most as of late, Pluto. We should have the capacity to get our own space explorers to space.
