When President Obama meets his counterpart President Enrique Pe?a Nieto in Mexico this week, three issues will likely dominate their conversation: border security, the economy, and immigration ??themes that are as inextricably tied as the two nations' physical border.

Mexico?s new government has shifted the national conversation on security away from one of drug war to crime prevention. It has promoted its economic prospects, and promised greater opportunities for Mexicans through reforms of everything from key industries to education.

Yet drug-related violence hasn?t abated, and that?s a concern for both Mexico and its northern neighbor. At meetings last month, representatives of both governments agreed to ?fundamentally restructure the way both countries manage their shared border,? according to a White House statement. The new approach aims to boost economic competitiveness and trade, improve public safety, and ?welcome lawful visitors.??

Mexico and the United States have long been important partners. But this week's meeting offers a fresh chance to expand the scope and depth of the conversation?on shared issues while each side promotes domestic reform agendas ? immigration in the US, and education and business reforms in Mexico ? that could affect how the two nations relate into the future.

?I think the main interest is to define the relationship more broadly,? says Eric Farnsworth, vice president of the Council of the Americas in Washington. ?Not walk away from or minimize the security agenda but to build a bigger story line for the relationship with Mexico.?

A competitive region

The US and Mexican economies have been in a process of ?silent integration? in the two decades since the signing of the North American Free Trade Agreement, according to Jorge Schiavon, professor of international relations at the public university CIDE in Mexico City. Now the question is, how can the two nations compete together with the rest of the world?

?What is needed is regional competitiveness in a global marketplace,? says Mr. Schiavon. ?North America must become more competitive."?

Nearly 80 percent of Mexican exports are destined for the United States but that statistic belies just how integrated the two economies are.

Forty percent of the goods exported to the US from Mexico contain US-made parts, says to Shannon O?Neil, author of "Two Nations Indivisible: Mexico, the United States, and the Road Ahead." To make a product like a car in Mexico, parts may have crossed the border dozens of times before the finished product is finally shipped north. By contrast, just 4 percent of exports to the US from China, Brazil, and the European Union have US-made content.

?In Mexico, it?s really a back and forth process, and it?s beneficial for US workers,? Ms. O?Neil says. ?This is something that has really happened since NAFTA. Trade has exploded; it?s changed the decision-making process.??

Mexicans appreciate this; According to Pew Research, 70 percent of Mexicans believe deep economic ties with the US benefit their country.?

Seahorse's armor gives engineers insight into robotics designs

May 1, 2013 ? The tail of a seahorse can be compressed to about half its size before permanent damage occurs, engineers at the University of California, San Diego, have found. The tail's exceptional flexibility is due to its structure, made up of bony, armored plates, which slide past each other. Researchers are hoping to use a similar structure to create a flexible robotic arm equipped with muscles made out of polymer, which could be used in medical devices, underwater exploration and unmanned bomb detection and detonation. UC San Diego engineers, led by materials science professors Joanna McKittrick and Marc Meyers, detailed their findings in the March 2013 issue of the journal Acta Biomaterialia.

"The study of natural materials can lead to the creation of new and unique materials and structures inspired by nature that are stronger, tougher, lighter and more flexible," said McKittrick, a professor of materials science at the Jacobs School of Engineering at UC San Diego.

McKittrick and Meyers had sought bioinsipiration by examining the armor of many other animals, including armadillo, alligators and the scales of various fish. This time, they were specifically looking for an animal that was flexible enough to develop a design for a robotic arm.

"The tail is the seahorse's lifeline," because it allows the animal to anchor itself to corals or seaweed and hide from predators, said Michael Porter, a Ph.D. student in materials science at the Jacobs School of Engineering. "But no one has looked at the seahorse's tail and bones as a source of armor."

Most of the seahorse's predators, including sea turtles, crabs and birds, capture the animals by crushing them. Engineers wanted to see if the plates in the tail act as an armor. Researchers took segments from seahorses' tails and compressed them from different angles. They found that the tail could be compressed by nearly 50 percent of its original width before permanent damage occurred. That's because the connective tissue between the tail's bony plates and the tail muscles bore most of the load from the displacement. Even when the tail was compressed by as much as 60 percent, the seahorse's spinal column was protected from permanent damage.

McKittrick and Meyers' research group uses a unique technique that applies a series of chemicals to materials to strip them of either their protein components or their mineral components. That allows them to better study materials' structures and properties. After treating the bony plates in the seahorse's tail with the chemicals, they discovered that the percentage of minerals in the plates was relatively low -- 40 percent, compared to 65 percent in cow bone. The plates also contained 27 percent organic compounds -- mostly proteins -- and 33 percent water. The hardness of the plates varied. The ridges were hardest, likely for impact protection -- about 40 percent harder than the plate's grooves, which are porous and absorb energy from impacts.

The seahorse's tail is typically made up of 36 square-like segments, each composed of four L-shaped corner plates that progressively decrease in size along the length of the tail. Plates are free to glide or pivot. Gliding joints allow the bony plates to glide past one another. Pivoting joints are similar to a ball-and-socket joint, with three degrees of rotational freedom. The plates are connected to the vertebrae by thick collagen layers of connective tissue. The joints between plates and vertebrae are extremely flexible with nearly six degrees of freedom.

"Everything in biology comes down to structures," Porter said.

The next step is to use 3D printing to create artificial bony plates, which would then be equipped with polymers that would act as muscles. The final goal is to build a robotic arm that would be a unique hybrid between hard and soft robotic devices. A flexible, yet robust robotic gripper could be used for medical devices, underwater exploration and unmanned bomb detection and detonation. The protected, flexible arm would be able to grasp a variety of objects of different shapes and sizes.

Risk of depression influenced by quality of relationships

Apr. 30, 2013 ? The mantra that quality is more important than quantity is true when considering how social relationships influence depression, say U-M researchers in a new study.

After analyzing data from nearly 5,000 American adults, the researchers found that the quality of a person's relationships with a spouse, family and friends predicted the likelihood of major depression disorder in the future, regardless of how frequently their social interactions took place.

Individuals with strained and unsupportive spouses were significantly more likely to develop depression, whereas those without a spouse were at no increased risk. And those with the lowest quality relationships had more than double the risk of depression than those with the best relationships.

The study, which was published online today in PLOS ONE, assessed the quality of social relationships on depression over a 10-year period, and is one of the first to examine the issue in a large, broad population over such a long time period.

Nearly 16 percent of Americans experience major depression disorder at some point in their lives, and the condition can increase the risk for and worsen conditions like coronary artery disease, stroke and cancer.

"Our study shows that the quality of social relationships is a significant risk factor for major depression," says psychiatrist Alan Teo, M.D., M.S., a Robert Wood Johnson Foundation Clinical Scholar at U-M and the study's lead author. "This is the first time that a study has identified this link in the general population."

Digging deeper into the results, the researchers found that certain positive and negative aspects of relationships also predicted depression. Social strain and a lack of support -- especially in spousal relationships and to some extent with family members -- were both risk factors for developing depression later.

"These results tell us that health care providers need to remember that patients' relationships with their loved ones likely play a central role in their medical care," Teo says. "They also suggest that the broader use of couples therapy might be considered, both as a treatment for depression and as a preventative measure."

While the results confirmed the researchers' assumptions about relationship quality, they did not find a correlation between the frequency of social interactions and the prevalence of depression as predicted. Even if participants were socially isolated, having few interactions with family and friends, it did not predict depression risk. Teo says this finding should also translate to mental health treatment considerations.

"Asking a patient how she rates her relationship with her husband, rather than simply asking whether she has one, should be a priority," Teo says.

The researchers say that the study's significant effect size -- one in seven adults with the lowest-quality relationships will develop depression, as opposed to just one in 15 with the highest quality relationships -- indicates the potential for substantial change in the general population.

"The magnitude of these results is similar to the well-established relationship between biological risk factors and cardiovascular disease," Teo says. "What that means is that if we can teach people how to improve the quality of their relationships, we may be able to prevent or reduce the devastating effects of clinical depression."

Comcast profit rises 17 percent in 1Q

(AP) ? Comcast Corp., the nation's largest cable company and owner of NBCUniversal, on Wednesday said its net income rose 17 percent in the latest quarter, powered by continued strong results from its cable operations.

Price increases on cable TV helped boost numbers, as subscribers paid an average of $3.40 more per month compared to the same period last year.

Comcast also continued to recruit new broadband and phone customers at a brisk pace, and broke 10 million phone customers for the first time in the quarter. It's the country's fourth-largest home phone company, behind AT&T, Verizon and CenturyLink.

The Philadelphia-based company earned $1.44 billion, or 54 cents per share, in the first quarter. That was up from $1.22 billion, or 45 cents per share, in the same quarter a year ago.

Analysts polled by FactSet were expecting earnings of 50 cents per share.

Revenue rose 2.9 percent to $15.31 billion. Analysts were expecting half a percent more, at $15.38 billion.

Comcast's revenue didn't grow as fast as usual because it broadcast the Super Bowl last year, but didn't this year. Excluding that effect, revenue would have grown 4.7 percent, it said.

Comcast lost 60,000 cable-TV subscribers, breaking a trend of slowing losses. However, it's still better than smaller cable companies at keeping customers in the face of competition from satellite and phone companies.

At NBCUniversal, revenue fell 2.4 percent compared to last year's quarter, when NBC aired the Super Bowl. CBS aired it this year. However, NBCUniversal's operating cash flow, a measure of profitability, rose.

As of March, Comcast owns all of NBCUniversal. It bought the 49 percent it didn't own from General Electric Co. for $16.7 billion. It bought it initial stake in 2011 and was planning to buy the rest over time, but announced in January that it was buying out GE years ahead of schedule.

Drive-By Shooter Sought After Deadly Nine-Car Crash In South Los Angeles (VIDEO)

Drive By Shooter South Los Angeles

Authorities are searching for a drive-by shooter that caused a deadly eight-car collision in South LA.

LOS ANGELES -- Los Angeles police are searching for a driver who caused a deadly eight-vehicle pileup while apparently fleeing after a drive-by shooting.

Officer Lyle Knight says someone opened fire at a carwash fundraiser in South Los Angeles shortly before 8 p.m. Tuesday.

Nobody was hit and the silver Pontiac took off. Witnesses or victims began chasing it in a Dodge Charger.

Minutes later, both cars ran a red light and slammed into cross-traffic. The Pontiac hit a Saturn, killing 39-year-old Jose Cuevas, of Downey.

The Charger hit a pickup truck, which struck parked cars and a bicyclist. The Los Angeles Times (http://lat.ms/14UQAuG) says the Charger's driver is in critical condition.

Police say five other people received minor injuries.

The Pontiac's driver is being sought.

South Africa slams UK decision to phase out aid

JOHANNESBURG (Reuters) - South Africa criticised Britain on Tuesday for a decision to phase out aid worth 19 million pounds ($29.5 million) a year, saying it was "tantamount to redefining" the relationship between Africa's biggest economy and its top investor.

British International Development Secretary Justine Greening told an African business conference this week that UK aid would end by 2015 in favour of a "new relationship based on sharing skills and knowledge, not development funding".

However, the announcement triggered a heated reaction from Pretoria, which said it was kept in the dark about the decision.

"This unilateral announcement no doubt will affect how our bilateral relations going forward will be conducted," foreign ministry spokesman Clayson Monyela said in a statement.

Greening was quoted on the UK government website as saying she had agreed with her South African counterparts on the need for a shift in development policy.

Despite pressure on public finances, Britain's Conservative government has pledged to increase aid spending to 0.7 percent of GDP, although it has made clear it will cut assistance to wealthier emerging states to boost it for poorer ones.

Last year, it said it would stop financial aid to India by 2015 amid domestic anger at annual handouts of 280 million pounds to Asia's third-largest economy while UK citizens were facing aggressive budget cuts.

Britain, South Africa's former colonial master, remains far and away its biggest investor, accounting for half of the country's 1 trillion rand ($110 billion) of foreign direct investment stock, according to central bank figures.

However, London's annual aid package, which focuses on public health and improving regional customs systems, is a drop in the ocean for Pretoria, whose budget forecasts spending of nearly $120 billion this year.
