Hundreds of millions of pieces of space junk orbit the Earth daily, from chips of old rocket paint, to shards of solar panels, and entire dead satellites. This cloud of high-tech detritus whirls around the planet at about 17,500 miles per hour. At these speeds, even trash as small as a pebble can torpedo a passing spacecraft.NASA and the U.S. Department of Defense are using ground-based telescopes and laser radars (ladars) to track more than 17,000 orbital debris objects to help prevent collisions with operating missions. Such ladars shine high-powered lasers at target objects, measuring the time it takes for the laser pulse to return to Earth, to pinpoint debris in the sky.Now aerospace engineers from MIT have developed a laser sensing technique that can decipher not only where but what kind of space junk may be passing overhead. For example, the technique, called laser polarimetry, may be used to discern whether a piece of debris is bare metal or covered with paint. The difference, the engineers say, could help determine an object’s mass, momentum, and potential for destruction.“In space, things just tend to break up over time, and there have been two major collisions over the last 10 years that have caused pretty significant spikes in debris,” says Michael Pasqual, a former graduate student in MIT’s Department of Aeronautics and Astronautics. “If you can figure out what a piece of debris is made of, you can know how heavy it is and how quickly it could deorbit over time or hit something else.”

For nearly sixty years, the CIA has resisted the Government Accountability Office’s (GAO) efforts to perform a full audit of the Agency, even going so far as to not only render themselves exempt, but to spread this exemption throughout the rest of the Intelligence Community. When the GAO got fed up and quit, the CIA tried to have the letters detailing their frustrations classified.
A New Jersey community college has fired an adjunct professor after officials say she made racially insensitive comments on Fox News.Lisa Durden was axed from Essex County College as the adjunct communications professor on Friday – roughly two weeks after she appeared on ‘Tucker Carlson Tonight’.
Essex County College’s president Anthony Munroe announced the decision Friday and said officials at the school had received complaints about her heated interview with Carlson. Durden, who is black, discussed a Memorial Day event held exclusively for black people hosted by a Black Lives Matter group in New York.When Carlson asked her her thoughts, Durden interrupted the host, saying: ‘Boo hoo hoo. You white people are angry because you couldn’t use your white privilege card’ to attend the event.’
She added, ‘You’ve been having ‘White Day’ forever’ as she defended the group for wanting to have ‘one day for black folks to focus on ourselves.’
Carlson called her comments during the roughly six-minute interview ‘hostile, separatist and crazy.’
The school suspended Durden two days after the show aired.
Durden said the school ‘publicly lynched’ her. The school on Friday said ‘racism cannot be fought with more racism.’
In a statement, Munroe said that families who contacted the school over her comments expressed frustration.
‘When the administration receives an outpouring of concern regarding our student body, it is our responsibility to investigate those concerns,’ he said.
SANTA FE, N.M. (AP) – The New Mexico Department of Health on Monday confirmed two more human cases of plague.The recent cases involve a 52-year-old woman and a 62-year-old woman. The first case this year was reported in early June in a 63-year-old man.All three patients, who live in Santa Fe County, were hospitalized but there have been no deaths.PreviousNext State public health veterinarian Paul Ettestad said plague can be present in fleas that infest wild rodents in Santa Fe County, including within the city limits of Santa Fe and in other locations around New Mexico.”Pets that are allowed to roam and hunt can bring infected fleas from dead rodents back into the home, putting you and your children at risk,” he said.Health workers are conducted environmental investigations around the homes of the three patients to look for ongoing risk and to ensure the safety of the immediate family members and neighbors.Plague generally is transmitted to humans through the bites of infected fleas but can be transmitted by direct contact with infected animals including rodents and pets. Symptoms include sudden onset of fever, chills, headache and weakness.According to the Centers for Disease Control and Prevention, plague is infamous for killing millions of people in Europe centuries ago. Antibiotics are now effective in treating the disease, but officials say without prompt treatment, it can cause serious illness or death.The CDC reports that hundreds of cases have been documented over the last century in the western United States, typically in northern New Mexico, northwestern Arizona and southern Colorado.In 2016, New Mexico had four human cases with no fatalities. Four cases were also reported in 2015 with one fatality.
A major global cyber attack on Tuesday disrupted computers at Russia’s biggest oil company, Ukrainian banks and multinational firms with a virus similar to the ransomware that last month infected more than 300,000 computers.The rapidly spreading cyber extortion campaign underscored growing concerns that businesses have failed to secure their networks from increasingly aggressive hackers, who have shown they are capable of shutting down critical infrastructure and crippling corporate and government networks.It included code known as “Eternal Blue,” which cyber security experts widely believe was stolen from the U.S. National Security Agency (NSA) and was also used in last month’s ransomware attack, named “WannaCry.””Cyber attacks can simply destroy us,” said Kevin Johnson, chief executive of cyber security firm Secure Ideas. “Companies are just not doing what they are supposed to do to fix the problem.”The ransomware virus crippled computers running Microsoft Corp’s (MSFT.O) Windows by encrypting hard drives and overwriting files, then demanded $300 in bitcoin payments to restore access. More than 30 victims paid into the bitcoin account associated with the attack, according to a public ledger of transactions listed on blockchain.info.
One of the first things you notice after opening a jar of Coco Loko is that it looks like hot chocolate mix. Snorting a line of the brown powder with specks of white confirms its familiar flavor, followed by a rush of energy.Americans are beginning to see the product alongside candy bars and energy pills at local shops as the Florida company Legal Lean moves to take a European club-drug trend mainstream.“I can see it taking off, as long as it doesn’t get too controversial,” says Nick Anderson, director of marketing for the five-person Orlando company. “We feel like we’re cutting edge in what we’re doing.”Snorting chocolate has received significant international attention since 2007, when Belgian chocolatier Dominique Persoone created a device he calls the Chocolate Shooter to snort cocoa (not cacao) powder. Health conscious European clubgoers separately use raw cacao in pills and drinks for its mildly euphoric, energizing effects.Coco Loko uses cacao, which is processed at a lower heat than cocoa, retaining more beneficial nutrients. Raw cacao is hailed as a superfood full of mood-lifting anandamide and phenylethylamine, cognition-assisting flavonoids and muscle-relaxing magnesium.Cacao can be purchased on Amazon.com or at a Walmart. Until now, however, powder specifically intended for snorting has not been a mass-market product in the U.S.Coco Loko is cut to enhance cacao’s effects. The label lists B vitamins, ginkgo biloba, blood flow-improving amino acid L-Arginine and the energy drink stimulants guarana and taurine.
Like many women, Canadian screenwriter and animation director Lori Malépart-Traversy seems to have gotten frustrated with the weird aura of ignorance surrounding what is after all the primary vehicle for female sexual pleasure. You may have heard of it: the clitoris.She took matters into her own hands (stop!) and created this smashing three-minute animated movie about this sometimes misunderstood sexual organ, which is so goddamned adorable, it’s easy to forget that the content is pretty much X-rated.(Even having said that, it’s difficult to imagine a group of ten-year-olds that would be substantially harmed by watching a short film as engaging, funny, and informative as this one. Chances are they’ve seen worse by that age.)The movie is in French but there are helpful English subtitles. Frankly it’s pretty clear what’s going on—or at least it should be, your mileage may vary—even with no text at all. I have to admit that my life is improved by having the phrase “clitoral obscurantism” added to it. (Damn you, Freud!!)One waits eagerly for the day when the utility of the clitoris and the importance of the female orgasm are acknowledged by all of humankind. In the meantime, watch this terrific video:
STRATFORD, Ontario — On the last Saturday afternoon in May, when the season’s first productions at the Stratford Festival were still in previews, visitors to its Tom Patterson Theater were greeted with two warnings at the auditorium entrance. One was the usual kind of advisory, a heads-up that the show they were about to see contained fog, haze, strobe lighting and mature content.The other sign, in a bold black frame, was more eyebrow-raising — partly because the phrase “mature content” had evidently been judged insufficient on its own. “This production includes explicit scenes of erotocism,” the second warning read.Aside from the misspelling, it wasn’t wrong. The director Jillian Keiley’s feminist staging of “Bakkhai” — a new translation, by the poet and classicist Anne Carson, of Euripides’ ancient Greek tragedy “The Bacchae” — practically pulses with sexual pleasure, almost all of it female. The women in the play, followers of the god Dionysos, revel in their carnality without self-consciousness or shame — a theme Ms. Keiley was deeply interested in exploring in her dreamlike production, which is lush with music and dance.
