That's the argument made by computer scientists M.P.Sivaram Kumar and S. Rajasekaran in a recent article in the Journal of Computing entitled "Path Planning Algorithm for Extinguishing
Forest Fires." Their thesis is simple: the vast majority of forests are destroyed by wild forest fires, and current methods of sylvan vigilance -- mainly those involved individual personnel on foot patrol -- are grossly inefficient in identifying emerging threats. Their pre-defined route may be damaged or obscured, inclement weather affects visibility, and life on patrol is boring and "miserable," leading to a lack of attention.
Kumar and Rajasekaran argue that deploying robotic systems throughout wooded areas will increase firefighters' ability not just to identify emerging threats, but also to more effectively plot the path of a wildfire, and then deploy the appropriate resources to the right places. The two imagine a grid-based system of automated drones, designed to detect abnormal changes in temperature and relay data back to a command center:
The automatic forest fire detection and extinguishing system consists of
nodes deployed deterministically in a forest area and all
the nodes know their location based on coordinate values
of a matrix. Each node is equipped with a temperature
sensor and an Omni directional antenna. Nodes continuously monitor the environment to check if there is fire or
not in the particular cell. When change in temperature i.e.
temperature raises above a certain threshold, is detected
by a particular node they send message packets which
contain location measurements. These packets are received by one of the corner node. The corner node then
sends the packet to the Actor which in turn will process
the packet which can be used in reaching the target area
to extinguish fire.
On-the-ground nodes, they argue, are significantly better than the preexisting satellite detection systems that, due to a long scan period and low resolution of images, end up detecting fires relatively late. Relying on satellites often means that firefighting personnel deploy more resources in their firefighting than would otherwise be necessary.
There are obvious environmental concerns to stringing a sprawling forest with robotic nodes. Introducing any man-made object, even stationary a drone, can have unintended consequences on a complex arboreal ecosystem. Unexpected costs -- a tree falling in the woods, surprise visits from assorted large mammals -- could make deploying and maintaining a robotic grids prohibitively expensive.
But among the significant additional benefits: potentially saving lives. Wireless Emergency Alerts (WEA), a system developed by FEMA, the FCC, and wireless carriers, will soon be deployed in emergency situations like severe weather to notify citizens of imminent threats to their safety. Within the next few weeks, nearly everyone in the country with a mobile phone could start receiving text messages from the National Weather Service, local law enforcement, or perhaps even the President. Here's how it works:
In the event of an emergency, an authorized alerting agency can select a cell tower (or towers) to broadcast a WEA. In order to receive the message, a person must be within range of the cell-tower broadcast, and must have a phone capable of "hearing" the the broadcast. Most cellular devices manufactured after mid-2011 already have this capability.
It is through the use of CB technology that CMAS is able to provide some geographic targeting without the need for opting-in. However, it is important to note that because WEAs are "broadcast" from towers, the geo-targeting feature is not as precise as GPS. GPS is a two-way street of communication between a GPS-equipped device and various positioning satellites. WEAs are not two-way...it is simply a modern day "shout" to give a heads-up that something requires your attention.
According to the National Fire Protection Association, only 11 people were killed in wildfire-related incidents in 2011. But application of the sensor technology to, say, rivers with a high likelihood of flooding, earthquake-prone regions, and other unstable natural centers could give first responders a useful heads-up. When tied in with FEMA's new WEA system, average citizens could have enough advance warning of danger to protect themselves in the event of a natural disaster. And in the event of a fast-moving fire or flood, a few extra minutes could mean the difference between life and death.
For anyone who has ever caught some treacly adult contemporary on the radio and wondered “Who on earth likes this stuff?” while twisting the dial, a new study might have an answer. A bunch of softies, that’s who.
In the paper, published recently in the online journal PLoS One, Cambridge psychologist David Greenberg theorized that music tastes are determined in part by peoples’ tendency to fall into one of two rough personality categories: empathizers or systemizers. Empathizers are people who are very attuned to others’ emotions and mental states. Systemizers are more focused on patterns that govern the natural and physical worlds.
Over the course of multiple experiments that included 4,000 participants, listeners took personality questionnaires and then listened to and rated 50 pieces of music.
A controversial treatment shows promise, especially for victims of trauma.
It’s straight out of a cartoon about hypnosis: A black-cloaked charlatan swings a pendulum in front of a patient, who dutifully watches and ping-pongs his eyes in turn. (This might be chased with the intonation, “You are getting sleeeeeepy...”)
Unlike most stereotypical images of mind alteration—“Psychiatric help, 5 cents” anyone?—this one is real. An obscure type of therapy known as EMDR, or Eye Movement Desensitization and Reprocessing, is gaining ground as a potential treatment for people who have experienced severe forms of trauma.
Here’s the idea: The person is told to focus on the troubling image or negative thought while simultaneously moving his or her eyes back and forth. To prompt this, the therapist might move his fingers from side to side, or he might use a tapping or waving of a wand. The patient is told to let her mind go blank and notice whatever sensations might come to mind. These steps are repeated throughout the session.
The Vermont senator’s revolutionary zeal has met its moment.
There’s no way this man could be president, right? Just look at him: rumpled and scowling, bald pate topped by an entropic nimbus of white hair. Just listen to him: ranting, in his gravelly Brooklyn accent, about socialism. Socialism!
And yet here we are: In the biggest surprise of the race for the Democratic presidential nomination, this thoroughly implausible man, Bernie Sanders, is a sensation.
He is drawing enormous crowds—11,000 in Phoenix, 8,000 in Dallas, 2,500 in Council Bluffs, Iowa—the largest turnout of any candidate from any party in the first-to-vote primary state. He has raised $15 million in mostly small donations, to Hillary Clinton’s $45 million—and unlike her, he did it without holding a single fundraiser. Shocking the political establishment, it is Sanders—not Martin O’Malley, the fresh-faced former two-term governor of Maryland; not Joe Biden, the sitting vice president—to whom discontented Democratic voters looking for an alternative to Clinton have turned.
Even when a dentist kills an adored lion, and everyone is furious, there’s loftier righteousness to be had.
Now is the point in the story of Cecil the lion—amid non-stop news coverage and passionate social-media advocacy—when people get tired of hearing about Cecil the lion. Even if they hesitate to say it.
But Cecil fatigue is only going to get worse. On Friday morning, Zimbabwe’s environment minister, Oppah Muchinguri, called for the extradition of the man who killed him, the Minnesota dentist Walter Palmer. Muchinguri would like Palmer to be “held accountable for his illegal action”—paying a reported $50,000 to kill Cecil with an arrow after luring him away from protected land. And she’s far from alone in demanding accountability. This week, the Internet has served as a bastion of judgment and vigilante justice—just like usual, except that this was a perfect storm directed at a single person. It might be called an outrage singularity.
Forget credit hours—in a quest to cut costs, universities are simply asking students to prove their mastery of a subject.
MANCHESTER, Mich.—Had Daniella Kippnick followed in the footsteps of the hundreds of millions of students who have earned university degrees in the past millennium, she might be slumping in a lecture hall somewhere while a professor droned. But Kippnick has no course lectures. She has no courses to attend at all. No classroom, no college quad, no grades. Her university has no deadlines or tenure-track professors.
Instead, Kippnick makes her way through different subject matters on the way to a bachelor’s in accounting. When she feels she’s mastered a certain subject, she takes a test at home, where a proctor watches her from afar by monitoring her computer and watching her over a video feed. If she proves she’s competent—by getting the equivalent of a B—she passes and moves on to the next subject.
Jim Gilmore joins the race, and the Republican field jockeys for spots in the August 6 debate in Cleveland.
After decades as the butt of countless jokes, it’s Cleveland’s turn to laugh: Seldom have so many powerful people been so desperate to get to the Forest City. There’s one week until the Republican Party’s first primary debate of the cycle on August 6, and now there’s a mad dash to get into the top 10 and qualify for the main event.
With former Virginia Governor Jim Gilmore filing papers to run for president on July 29, there are now 17 “major” candidates vying for the GOP nomination, though that’s an awfully imprecise descriptor. It takes in candidates with lengthy experience and a good chance at the White House, like Scott Walker and Jeb Bush; at least one person who is polling well but is manifestly unserious, namely Donald Trump; and people with long experience but no chance at the White House, like Gilmore. Yet it also excludes other people with long experience but no chance at the White House, such as former IRS Commissioner Mark Everson.
The Wall Street Journal’s eyebrow-raising story of how the presidential candidate and her husband accepted cash from UBS without any regard for the appearance of impropriety that it created.
The Swiss bank UBS is one of the biggest, most powerful financial institutions in the world. As secretary of state, Hillary Clinton intervened to help it out with the IRS. And after that, the Swiss bank paid Bill Clinton $1.5 million for speaking gigs. TheWall Street Journal reported all that and more Thursday in an article that highlights huge conflicts of interest that the Clintons have created in the recent past.
The piece begins by detailing how Clinton helped the global bank.
“A few weeks after Hillary Clinton was sworn in as secretary of state in early 2009, she was summoned to Geneva by her Swiss counterpart to discuss an urgent matter. The Internal Revenue Service was suing UBS AG to get the identities of Americans with secret accounts,” the newspaper reports. “If the case proceeded, Switzerland’s largest bank would face an impossible choice: Violate Swiss secrecy laws by handing over the names, or refuse and face criminal charges in U.S. federal court. Within months, Mrs. Clinton announced a tentative legal settlement—an unusual intervention by the top U.S. diplomat. UBS ultimately turned over information on 4,450 accounts, a fraction of the 52,000 sought by the IRS.”

All hail ¯\_(ツ)_/¯.
In its 11 strokes, the symbol encapsulates what it’s like to be an individual on the Internet. With raised arms and a half-turned smile, it exudes the melancholia, the malaise, the acceptance, and (finally) the embrace of knowing that something’s wrong on the Internet and you can’t do anything about it.
As Kyle Chayka writes in a new history of the symbol at The Awl, the meaning of the “the shruggie” is always two, if not three- or four-, fold. ¯\_(ツ)_/¯ represents nihilism, “bemused resignation,” and “a Zen-like tool to accept the chaos of universe.” It is Sisyphus in unicode. I use it at least 10 times a day.
For a long time, however, I used it with some difficulty. Unlike better-known emoticons like :) or ;), ¯\_(ツ)_/¯ borrows characters from the Japanese syllabary called katakana. That makes it a kaomoji, a Japanese emoticon; it also makes it, on Western alphabetical keyboards at least, very hard to type. But then I found a solution, and it saves me having to google “smiley sideways shrug” every time I want to quickly rail at the world’s inherent lack of meaning.
The Islamic State is no mere collection of psychopaths. It is a religious group with carefully considered beliefs, among them that it is a key agent of the coming apocalypse. Here’s what that means for its strategy—and for how to stop it.
What is the Islamic State?
Where did it come from, and what are its intentions? The simplicity of these questions can be deceiving, and few Western leaders seem to know the answers. In December, The New York Times published confidential comments by Major General Michael K. Nagata, the Special Operations commander for the United States in the Middle East, admitting that he had hardly begun figuring out the Islamic State’s appeal. “We have not defeated the idea,” he said. “We do not even understand the idea.” In the past year, President Obama has referred to the Islamic State, variously, as “not Islamic” and as al-Qaeda’s “jayvee team,” statements that reflected confusion about the group, and may have contributed to significant strategic errors.
50 years after closing its schools to fight racial integration, a Virginia county still feels the effects.
I was sitting in the dark den of the last living founder of the white private school I had attended, an academy established after public schools in my Virginia hometown were closed in 1959 to avoid desegregation. Having worked as a reporter for years, I was used to uncomfortable conversations. But this one felt different. This conversation was personal.
I wanted to interview Robert E. Taylor about desegregation in Prince Edward County and to find out how he felt about it in 2006, decades later. Weeks before his death, he told me he was still a “segregationist” and expressed no remorse for the school closings. Breathing with the help of an oxygen machine, he used tired stereotypes to describe black teenagers in my hometown as dating white teens, impregnating them, and leaving the teenage girls’ families with “pinto” babies that nobody would want.
