Podcast: What You Should Know for Nov. 4

CMU Insider has started a new format for “What You Should Know.” In addition to telling you what’s happening on our campus, state and nation, we have added a world, science/technology and business section. There is also a podcast version.

From the Morning Sun:

A Central Michigan University student who hadn’t been seen since mid-October was found within 24 hours after police were notified….

Jayjuan Casey, a 17-year-old Southfield freshman had last been seen on Oct. 13 leaving a class on campus, according to CMU Police, who were not notified until Monday that Casey was missing.
On Tuesday the department posted information to their Facebook and Twitter accounts, including photos and description of Casey’s physical appearance; within 30 minutes, they had located him.
“He called the department and we were able to verify his identity using personal information only he was likely to know. He appears to be safe and sound,” said Lt. Cameron Wassman.
Casey, who Wassman said has some outstanding criminal warrants for arrest for “some minor things,” told police he was out of town.
As police began piecing together Casey’s last known whereabouts Monday, it became evident no one could verify having actually seen him in several weeks, despite the fact that he was enrolled in classes and lived in Thorpe Hall, a campus dormitory.
“I’m not sure how that happens,” Wassman said. “But from a law enforcement standpoint, this was a success; we found (Casey), safe, within 24 hours of it being reported.”

A CMU freshman was killed early Sunday morning when he was struck by a vehicle while walking with a group of friends shortly after midnight.

More from The Morning Sun:

The Macomb student, who police say was two weeks shy of his 18th birthday, was walking on Crawford between Bilbrael and Concourse north of Deerfield road with a group of friends shortly after midnight on a dark and rainy Halloween night when a car hit him and drove off, said State Police Sgt. Kimberly Vetter.
The stretch of road just over the west edge of campus is poorly lit and there are no sidewalks; many of the public right-of-way areas on the sides of the road slope down into ditches.
Police are asking for the public’s help locating the driver of the car, which is described as an older four-door that is dark in color. Vetter said it will likely have damage to the front passenger side.
Anyone with information can contact Isabella County Central Dispatch at 989-773-1000 or the Mt. Pleasant State Police Post at 989-773-5951.
Police said the victim was heading to his room in Merrill Hall in the south quad residence hall complex. He was pronounced dead at the scene of the crash.
It’s unknown if drugs or alcohol were involved; no one else walking with the man was injured, Vetter said.

The invasive Asian carp has been found 12 miles closer to Lake Michigan. U.S. Sen. Debbie Stabenow on Sunday urged the Obama administration to take “immediate action” to respond to the threat after U.S. Fish and Wildlife made the discovery.
More from the Detroit Free Press:

“I remain extremely concerned that Asian carp are getting closer and closer to Lake Michigan,” Stabenow, D-Mich., told the Free Press. “Time is running out.”
Nonnative to the Americas, the fish species known collectively as Asian carp are voracious eaters and worries are high that they could decimate habitat and food sources for fish throughout the Great Lakes if they reach Lake Michigan.
Late last week, the Asian Carp Regional Coordinating Committee, a group of federal and state agencies monitoring the spread of the invasive carp, reported that Fish and Wildlife crews detected two small silver carp upstream of Seneca, Ill., in the Illinois River, on Oct. 22. Each of the fish measured about 6 ½ inches in length.
Silver carp are one of the species otherwise known collectively as Asian carp. News of the find, reported on the coordinating committee’s website, noted that the small fish were found approximately 12 miles closer to the lake and that it “brings the leading edge of juvenile Asian carp detections about 66 miles closer to Lake Michigan than it was at the beginning of 2015.”
The committee also noted, however, that carp are still farther than 76 miles from Lake Michigan and that several dams, as well as the Army Corps of Engineers’ electric dispersal barriers, remain between the leading edge of the carp and the lake.

According to a new Reuters/Ipsos poll of Republicans conducted after the party’s third debate, Donald Trump is the Republican candidate most trusted to manage the economy, deal with foreign leaders and serve as commander-in-chief.
More from Reuters:

In terms of overall support, Trump was favored by 31 percent of Republicans polled by Reuters/Ipsos in an online survey conducted Oct. 28 to Nov. 2 that had a credibility interval of plus or minus 4.4 percentage points. Retired neurosurgeon Ben Carson placed second with 18 percent. Senator Marco Rubio of Florida and former Governor Jeb Bush tied for third place with 10 percent each.
For anyone still confused about why Trump is holding strong onto a double-digit lead in most presidential primary polls, look no farther than at how much Republican voters trust him. The growing trust shows Trump’s campaign message – that his experience in business means voters should pick him to negotiate trade deals or take on Russia’s Vladimir Putin – is resonating.
On the question of whether voters trust the candidates to manage the economy, 59 percent said “yes” to Trump.
None of the other Republican candidates came even close. Carson was second, with 36 percent saying they trust him to manage the economy. Rubio was third with 27 percent, followed by retired business executive Carly Fiorina at 25 percent.
It’s not just on the economy where Trump shines. Asked whether they trusted the various Republican candidates to be commander in chief, Trump and Carson were tied, at 40 percent each.
On the question of whom they trusted to deal with foreign leaders, Trump again took top marks, with 41 percent saying they would trust the New York real estate mogul. Carson was a close second at 39 percent. Rubio, who has made foreign policy a central part of his campaign and stressed his experience on the Senate Foreign Relations Committee, was third at 31 percent.
Asked about handling the nation’s nuclear weapons – another insight into voters’ views on foreign policy – 34 percent of Republicans said they would trust Trump. He trailed only Carson, with 39 percent saying they would trust Carson to have his finger on the proverbial button. Only 27 percent said they would trust Rubio.

New Delhi is messy. Since late last month sanitation workers have been on strike, refusing to pick up garbage and even dumping piles of trash in the streets.
More from USA Today:

The capital generates 9,000 metric tons of waste every day. Residents have complained that it’s irresponsible for workers to abandon the city in the middle of the festival season, a time during which trash volume has been known to spike 30%. But it’s the city that has abandoned the people who clean it up, workers contend.
Sanitation workers have one key demand: their salaries. Of the three city government units in the capital, East Delhi alone owes its 14,000 workers $30 million. That amounts to well over $2,000 each owed to workers who only make $5-10 a day.
A pending payment of that size represents a crushing income deficit.
“I was married, but my wife and child have left me because I couldn’t provide for them. I am also very ill now,” said Joginder, a 37-year-old Delhi resident who has been a sanitation worker for 18 years. He hasn’t been paid for three months. “I am so tired of my life, it feels like a burden.”
Despite his difficulties, Joginder has it easier than many of the people he works with. He is a “regularized” worker, being paid a monthly salary unlike temporary workers who earn a daily wage. Daily wage-earners make half the amount permanent workers do, just $5 a day.
This isn’t the first time this year that pay for Delhi’s cleaners has been held up. Sanitation workers went on strike in June after months of waiting for their pay. It took 12 days of demonstrations to get the government to agree to release their salaries.
It didn’t take long for the payments to stop again. Rajendra Mewati, a sanitation workers’ union leader, says the workers who are getting by are doing it on credit. “As they don’t get paid they have to take out loans, and then they have to live their lives in debt,” he said. “We simply want (the municipalities) to implement the policies they already have.”
But the mayor of the East Delhi Municipal Corporation, Harsh Deep Malhotra, claims the municipal body is helpless.

The automobile industry is headed for record sales this year.
More from Reuters:

GM said the six-month rolling average for U.S. auto sales is 17.8 million on an annualized basis, which means the industry is on its way to beating the 1999 annual sales record.
October sales will come in around 18.2 million vehicles on an annualized basis, their highest level since 2001, when automakers offered 0 percent financing in the aftermath of the Sept. 11 attacks, the company said.
In 2009, at the depth of the Great Recession, U.S. auto sales dipped to 10.4 million vehicles.
Analysts had forecasted October sales to be between 8 percent and 12 percent higher than last year. A Reuters poll of 45 economists showed expectations of a seasonally adjusted annualized sales rate of 17.7 million vehicles for last month.
“October was a huge month for the industry, smashing expectations and continuing its hot streak,” said Bill Fay, Toyota’s U.S. general manager.
The booming October sales materialized despite concerns about a slowdown in consumer spending and stagnant wages.
U.S. economic data suggests consumer spending lost momentum at the end of the third quarter, with consumption in September posting its smallest increase in eight months. Personal incomes also barely rose that month.
GM said its sales rose 16 percent to 262,993 vehicles last month, marking its best October since 2004. GM shares dipped 4 cents to $35.53 on the New York Stock Exchange.

There may be a new method to facilitate faster computing–sing to it. A team of engineers may have found the answer to faster computing using minimal power: sound. The research has shown that certain types of sound waves can move data quickly, using minimal power.
More from Science Daily:

Nothing is more frustrating that watching that circle spinning in the centre of your screen, while you wait for your computer to load a programme or access the data you need. Now a team from the Universities of Sheffield and Leeds may have found the answer to faster computing: sound.
The research — published in Applied Physics Letters — has shown that certain types of sound waves can move data quickly, using minimal power.
The world’s 2.7 zettabytes (2.7 followed by 21 zeros) of data are mostly held on hard disk drives: magnetic disks that work like miniaturised record players, with the data read by sensors that scan over the disk’s surface as it spins. But because this involves moving parts, there are limits on how fast it can operate.
For computers to run faster, we need to create “solid-state” drives that eliminate the need for moving parts — essentially making the data move, not the device on which it’s stored. Flash-based solid-state disk drives have achieved this, and store information electrically rather than magnetically. However, while they operate much faster than normal hard disks, they last much less time before becoming unreliable, are much more expensive and still run much slower than other parts of a modern computer — limiting total speed.
Creating a magnetic solid-state drive could overcome all of these problems. One solution being developed is ‘racetrack memory’, which uses tiny magnetic wires, each one hundreds of times thinner than a human hair, down which magnetic “bits” of data run like racing cars around a track. Existing research into racetrack memory has focused on using magnetic fields or electric currents to move the data bits down the wires. However, both these options create heat and reduce power efficiency, which will limit battery life, increase energy bills and CO2 emissions.
Dr Tom Hayward from the University of Sheffield and Professor John Cunningham from the University of Leeds have together come up with a completely new solution: passing sound waves across the surface on which the wires are fixed. They also found that the direction of data flow depends on the pitch of the sound generated — in effect they “sang” to the data to move it.
The sound used is in the form of surface acoustic waves — the same as the most destructive wave that can emanate from an earthquake. Although already harnessed for use in electronics and other areas of engineering, this is the first time surface acoustic waves have been applied to a data storage system.
