The U.S. Navy has halted receipt of Freedom-class littoral combat ships from Lockheed Martin, citing a design flaw with potentially disastrous outcomes.
At issue is a major design flaw in the combining gear of the ship's transmission, a complex set of gears transferring power from its engines to its propulsion system.
The problem was disclosed last year, when the Navy Sea Systems
When the topic of sleep comes up in conversation, it's frequently because we're commiserating with friends or colleagues about how tired we feel after not getting near enough. In a world where a lot of people are really damn exhausted, the idea of getting too much sleep is laughable. But as it turns out, the phrase "too much of a good thing" applies here, too. According to doctors, sleeping too much can be a sign of an underlying medical condition and, if it's not addressed, it can potentially be harmful to your health in the long-term.
Every person's body is different and the amount of sleep we need varies - but doctors agree that healthy adults require between seven and eight hours per night. "Most people need seven hours of sleep to feel refreshed and alert the following day," James A. Rowley, MD, chief of the Division of Pulmonary, Critical Care & Sleep Medicine at DMC's Detroit Receiving Hospital, told POPSUGAR. "A minimum of seven hours is recommended by the American Academy of Sleep Medicine."
Sanam Hafeez, PhD, a New York City-based neuropsychologist and faculty member at Columbia University, told POPSUGAR that sleeping too much can also be a sign of a mental health condition such as depression. "People with depression are more likely to experience fatigue, and people with chronic fatigue are more likely to become depressed, creating a cycle that can be hard to break," she explained. It's also worth noting that many individuals who have anxiety and depression are on medications that can cause drowsiness - so if you're taking an anti-anxiety or antidepressant medication and sleeping more than the average adult, it's worth talking with your doctor about the pros and cons of possibly changing your medication.
Experiencing fatigue despite getting at least eight hours of sleep per night can also be a symptom of chronic illnesses including fibromyalgia, lupus, myalgic encephalomyelitis (more commonly referred to as chronic fatigue syndrome), and Hashimoto's disease. "If a person thinks they are sleeping too much and feels sleepy and fatigued during the day, they should discuss with their primary care physician or consider a consultation with a sleep physician," Dr. Rowley said.
Whether sleeping too much is the result of sleep apnea, a chronic physical illness, or depression, it's often a sign that something is wrong - and, although the idea of sleeping 10 to 12 hours per night may sound like a dream to some people, Dr. Rowley told POPSUGAR that there's evidence that long sleep times (generally more than nine hours per night) are associated with increased co-morbidities such as heart disease and mortality.
There's no need to immediately panic if you sleep too much - but it does mean it's time to make an appointment with a medical provider who can help you determine the cause and possible solutions.
Societies have long grappled with where to draw the chronological age boundary between adolescence and adulthood. The United States stands apart from most of the world in that it uses different ages for different rights and responsibilities. We permit people to drive when they are 16 (even younger in a few states), but prohibit them from purchasing alcohol until they are 21. The ages at which adolescents can see a risqué movie, choose to marry, enter into contracts, or buy cigarettes generally fall between these two extremes.
Nearly all other countries use one age — almost always, 18 — to distinguish between minors and adults for most legal purposes. This one-age-fits-all regime has the advantages of consistency, clarity and fairness. Once you’re an adult, you’re an adult.
Taking an issue-specific approach permits society to align legal responsibilities and privileges with people’s abilities and needs. It also allows citizens to change our collective mind about particular boundaries when events dictate rethinking them, as was the case when demonstrations over the Vietnam War draft prompted Congress to lower the voting age from 21 to 18.
The Parkland school shooting, in which 17 high school students and staff were killed by a 19-year-old with a semiautomatic assault rifle, may be another one of these transformative events. The massacre has understandably prompted a national discussion about gun control, but this is not the only policy debate that this tragedy should stimulate.
Three age-related revisions to the law, in particular, deserve careful consideration in the wake of the shooting: increasing the minimum age for purchasing firearms, lowering the voting age and raising the age of eligibility for capital punishment.
In order to understand how the new science of adolescence can inform this discussion, we need to differentiate between “cold” and “hot” cognition. Cold cognition is invoked in quiet situations, when you’re alone and unhurried. Here the most important skills are those measured by standardized tests of basic intellectual abilities, including attention, memory and logical reasoning.
Hot cognition is what kicks in when you are excited, agitated, in groups, or rushed. Under these circumstances, the most important skill is self-control, which enables us to regulate our emotions, resist coercion and think before we act.
For the past 20 years, my colleagues and I have been studying the developmental timetables of cold and hot cognition. Our initial research was conducted in the United States, but our most recent study included more than 5,000 people between ages 10 and 30 in 11 countries in Europe, Asia, Africa, the Middle East, and North and South America. The age trajectories we discovered were the same in our international sample as they were in the United States study.
Our studies show that the abilities necessary to make reasoned decisions are mature by age 16. By this age, adolescents can gather and process information, think logically and draw evidence-based inferences.
Self-regulation does not mature until around age 22, however. Not until this age are people capable of restraining themselves when their emotions are intense, when they are pressured by their peers, or when they feel hurried.
These findings on the development of cold and hot cognition parallel patterns of adolescent brain development. Neuroimaging studies show that brain systems necessary for cold cognition are mature by mid-adolescence, whereas those that govern self-control are not fully developed until the early 20s.
Growing into privileges
Most people would agree that individuals who have trouble controlling their emotions or thinking through the consequences of their acts should not possess deadly weapons. This, after all, is the rationale behind prohibiting those with serious mental illness from purchasing assault rifles and other firearms. (Even the staunchest defenders of Second Amendment rights, including President Trump, favor placing restrictions on the sale of guns to the mentally ill.)
Adolescence is not a mental illness, but it is a time during which many mentally healthy people have difficulty controlling their impulses and regulating their behavior. Based on the science, I agree with Florida’s Republican Gov. Rick Scott that people should not be permitted to purchase firearms until they are at least 21, if not older.
Voting, in contrast, is an act for which cold cognitive abilities are sufficient for competence. An election unfolds over months, which diminishes time pressure and permits people to gather facts and weigh them. Although you might discuss your preferences with others, the act of voting is done alone, and you have as much time as you want to deliberate inside a voting booth.
Marjory Stoneman Douglas student Emma Gonzalez calls out President Trump and the NRA at an anti-gun rally.
It is quite clear from post-Parkland events, during which we have witnessed many examples of wise, articulate and informed young people discussing gun control, that high school students are able to understand and speak knowledgeably about political issues that affect them. There is no reason why people who have the intellectual skills necessary to vote should be prohibited from doing so.
Teenagers may make bad choices, but they won’t make them any more often than adults do. As I noted in a recent op-ed in The New York Times, I believe the U.S. ought to lower the voting age to 16, as several countries in Europe and South America have done.
A question of juvenile responsibility
Deciding how to sentence the 19-year-old Parkland attacker, Nikolas Cruz, is certain to be controversial. In its 2005 decision in Roper v. Simmons, the U.S. Supreme Court abolished the juvenile death penalty on the grounds that adolescents are inherently less mature than adults and therefore not deserving of punishments reserved for those who are fully responsible for their crimes.
In the last five years, neuroscientific evidence has accumulated showing that many of the deficiencies characteristic of the juvenile brain continue to be evident after age 18. It makes sense for courts to consider people to be less than fully responsible for their criminal acts up to the age of 21.
In 2017, I presented this science in Commonwealth of Kentucky v. Diaz, a case involving a 20-year-old accused of murder. That court agreed that the logic of Roper should apply to people up to age 21, and that the death penalty could not be considered as a possible sentence for Mr. Diaz. The case is now under appeal.
Nikolas Cruz’s public defenders have offered prosecutors a guilty plea and their willingness to accept a life sentence in return for the state’s agreement to not pursue the death penalty. To date, the prosecutors have not announced their intentions. Although given the enormity of Cruz’s crime, there will surely be a public outcry pushing for the death penalty, the science is on the defense’s side.
Research on adolescent brain and psychological development can inform debates about where to draw legal lines between minors and adults. Science is not the only consideration when society contemplates changes in the law. But to the extent that people care to align social policies with current understanding of human development, the science of adolescence can help guide the discussion.

Ryan Giggs set to send in a cross – (Photo: Article.wn.com)
Whether you play fullback or winger, you should be well trained on sending in crosses. When you send in a cross, good things often happen. You may connect with a striker or a teammate who heads or volleys the cross in for a shot on the goal. Or, you may confuse the defenders or goalies into making a drastic error. Such errors can result in the ball left lying for your teammate to blast home for a goal. But getting your cross to be the ideal pass for your team is no easy feat, and lazy crosses rarely find their targets. Therefore, here are some tips for you to improve on making a cross:
Learn how to kick the soccer ball. This seems pretty basic, but getting a good kick on the ball is absolutely vital to playing the wing and making a solid cross. Young soccer players often have issues generating the proper power and placement on the ball. So what advice do I have? Practice, practice, practice. Learn how kick the ball and get some elevation on it. The only way to master this is to head out to a field with a ball and simply kick it over and over again until you get a grasp of how to really blast it.
Now, when you come into a game situation, you will want to learn the best times to make a cross. The best crosses are early crosses because much of the defense hasn’t tracked back to the opponent’s penalty box. When you send in an early cross as you sprint down the field, your striker may only have to compete with one defender to win the ball. That greatly increases the odds of a successful connection.
Meanwhile, if you were to wait, or send in a cross while the opposition is packed in at the back, your striker may have to contend with three or four defenders. Such a cross rarely creates a goal-scoring chance. Therefore, when an opening presents itself, take it. Don’t wait around for defenders to get in position.
Another tip for crossing is to play to your striker’s skills. If the striker is tall and has an aerial advantage over the defenders, it’s probably best to aim for his or her head, and an aerial cross will work best. Though if the striker is small and better suited to kick the ball, then send in a low cross. Think about your teammates and how to send in the best cross for them since they will have to receive the ball.
Lastly, be sure to look up before sending in a cross. Nothing is more wasteful than blasting a cross ahead when you have no teammates within 30 yards of the penalty box. Looking up will also help you pick out the best spot for your teammate to run to. See where they are headed and put the ball there.
There you have it. These tips should help you get started on your way to putting in the best crosses imaginable and help you start racking up those assists. But the first step is learning to really kick a soccer ball. So stop reading this, head outside, and practice kicking the ball!
For those of you who watched the International Friendlies Cup Final between Chelsea and Real Madrid last night it was proof of the article written a few months back titled, “The Evolution of the Outside Back.” Real Madrid came out flying with their outside back Marcelo playing almost as another outside left mid. He continually linked up with Cristiano Ronaldo and got several good chances. Real Madrid got on the scoreboard first as Marcelo made a run into the box, played a one-two with Ronaldo, and finished brilliantly between the legs of Gary Cahill who was trying to block his shot. In the modern game, you must be able to attack with your outside backs.
The first part of this article is explaining how to attack with your outside backs and the second part will be on how to defend a team who attacks with their outside backs. Whichever side the ball is on is the side in which your outside back will be making a run. Once this defender either receives the ball and begins to go forward or they begin to make their run forward your back four (assuming you’re playing with four in the back) will shift into a back three. Where the central defender on the side in which the outside back who is going forward, becomes the outside back. The other central defender shifts into a single central defender role and the other outside back on the other side continues to play their position, but they might pinch in toward the middle a little bit. They key is making sure everyone in the back is on the same page and communicating.
Another vital part of this kind of attack is making sure your defensive midfielder is holding a bit more when you are attacking with an outside back. Suppose the other team intercepts a square pass and begins to go on the counter. In this situation the defensive midfielder has a few options. If they are close to where the ball is intercepted they become the first defender and should immediately apply pressure to try to win possession back. If they can’t win possession, this would be a good time to make a “professional foul.” A professional foul is an intentional foul that slows down a counter attack. In this situation you will most likely receive a yellow card but that is better than a goal. Be cautious about this type of foul, a simple tug of the jersey will suffice. If the interception takes place and the defensive midfielder is not within the proximity, they should immediately retreat into a central defender role which will give you your back four again. When possession is lost, the other central midfielder(s) should be on their horse to get back behind the ball to apply pressure. At the same time the outside back who was attacking should be on a sprint back so the team can regain their shape.
Defending a team that attacks with their outside backs can be a difficult task. What this does is gives you a lot of 2v1 situations against your outside backs or outside midfielders. Your outside midfielder should be the first defender who either applies pressure or follows their run. In turn, the central midfielders need to begin to pinch in towards the side of the field in which the ball is on. The tighter the space the more difficult it will be for a quick one-two to be played.
Another option if you want to be less reactive and more proactive is to ignore the outside back and put a player with a lot of speed at outside mid. This is what Chelsea did against Real Madrid. In the second half they put Moses who is known for his speed on the outside, we did not see at much attack from Marcelo in the second half. He was forced to stay back and defend because of the threat of Chelsea’s counter through Moses.
The outside back has become a position where this type of player needs to be one of the most fit. They need to be able to get up and down the sideline and provide in the attack. This will require lots of communication with both the defenders and the midfielders to rotate their shape to defender against a possible counter. Get your outside backs forward, let them become part of the attack, and watch as you gain more goal-scoring opportunities.
