Could global warming change tornado season, too?
http://hosted.ap.org/dynamic/stories...03-15-16-06-56
Quote:
But as the traditional tornado season nears, scientists have been pondering a simple question: Will there be more or fewer twisters as global warming increases?

There is no easy answer. Lately, tornado activity in America has been Jekyll-and-Hyde weird, and scientists are unsure if climate change has played a role in recent erratic patterns.

The thing about climate change is that as a nonlinear system nears a tipping point, the attributes of the system become less stable, more violent, more unpredictable. When the tipping point of the equation is reached, the system *races* for a new region of stability.

That new region of stability may or may not be friendly to humans and their civilization. That's how nonlinear systems *work* and it's why having anti-science anti-math idiots at the helm is so dangerous. "I'm sorry" doesn't help much when the planet is covered in snow a mile deep or is tropical from pole to pole and formerly contained diseases wipe everyone out.

Well there is the fact that the planet has been both those extremes without humans even existing. So they look at it was a potental cycle and natural.

The argruements tend to be over if it is humanities fault or of humanity should try to correct it (correcting could make it worse for all we know, because we don't know what we are doing).

The other arguements tend to be over proofs as people tend to point to the colder winters as evidence against "global warming" as the logic goes "well shouldn't it be warmer, not colder". Which on the local level makes sense. Save that I know that in Minnisota they are having warm winter after warm winter verse back in the 50s and 60s. But in other place they are having winters like old Minnisota where they use to have mild winters.

NASA TO THE RESCUE! That said, it won't resolve queries about people trying to respond to global warming with the statement: "The planet goes through natural hot and cold cycles!"

We can consider mass or "average" extinctions in our plant as part of the natural cycle, but I do not think we should allow them, even if there will be another cycle of fauna in the planets millions of years later, if humans are wiped out then it worries me. You could call my line of thinking against mother earth best wishes, maybe we are a cancer and mother earth is trying at all costs to get rid of us, but it is human nature to prevail.

I think it is problematic so much time and energy is wasted in the "who is the culprit of global warming". Whether we had or not most/some/none of the blame it is irrelevant, the continuous accumulation of heat on the biosphere is bad news, the only thing we do not know for sure it is when it will start changing beyond our ability to cope with the changes/deaths.

It is the same as when you left your fridge open for defrosting, it is getting warmer even though when you get near it you feel the cold.

What people always seem to overlook are the news about melting ice caps in relation to the planetary energy balance.
Ice is a huge energy sink.
With the same energy you need to melt ice, just transforming 0°C cold ice into water without heating it up whatsoever, you could also heat that same amount of 0°C cold liquid water to 81°C!
And we are melting through our ice reserves at incredible speeds right now.

Once there is no more ice left to melt, we suddenly have a huge surplus on energy entering the system, that has to go somewhere else. Incoming heat spike...

Pew Pew! Scientists Build Lasers Out of Sound, Call Them Phasers:

"Using a nanoscale drum, scientists have built a laser that uses sound waves
instead of light like a conventional laser.

Because laser is an acronym for “light amplification by stimulated emission of
radiation,” these new contraptions – which exploit particles of sound called
phonons – should properly be called phasers. Such devices could one day be
used in ultrasound medical imaging, computer parts, high-precision
measurements, and many other places."

U.S. sends new satellite into space to monitor missile launches

Quote:
The 192-foot (58-meter) rocket lifted off from its seaside launch pad at 5:21 p.m. EDT/2121 GMT, carrying the U.S. Air Force's second Space Based Infrared System Geosynchronous, or Geo2, satellite.

Once operational, the spacecraft will join an orbital surveillance network that continually scans the globe for telltale signs of missile launches.

The Super Protein That Can Cut DNA and Revolutionize Genetic Engineering:

"When scientists Phillipe Horvath and Rodolphe Barrangou set out to find a better
way to make yogurt, they didn't expect to stumble across one of the future's most
promising discoveries: a super protein that can accurately cut DNA—and could
perhaps revolutionize genetic engineering."

Testing a New Class of Speedy Computer:

"Ray Johnson, Lockheed’s chief technical officer, said his company would use the
quantum computer to create and test complex radar, space and aircraft systems.
It could be possible, for example, to tell instantly how the millions of lines of
software running a network of satellites would react to a solar burst or a pulse
from a nuclear explosion — something that can now take weeks, if ever, to
determine.

“This is a revolution not unlike the early days of computing,” he said. “It is a
transformation in the way computers are thought about.” Many others could find
applications for D-Wave’s computers. Cancer researchers see a potential to move
rapidly through vast amounts of genetic data. The technology could also be used
to determine the behavior of proteins in the human genome, a bigger and
tougher problem than sequencing the genome. Researchers at Google have
worked with D-Wave on using quantum computers to recognize cars and
landmarks, a critical step in managing self-driving vehicles."

Should science on brain injury inspire a ban on boxing?

Quote:
(Reuters) - When Ireland's Katie Taylor was taking hits and striking blows for boxing's Olympic debut in an east London ring last year, John Hardy did not want to look.

To this leading neuroscientist and molecular biologist, a boxing bout is little more than a session of mutual brain injury. He was horrified to see women boxing at Olympic level for the first time at the London 2012 Games.

"We shouldn't get our fun out of watching people inflict brain damage on each other," said Hardy, who is chair of Molecular Biology of Neurological Disease at University College London's Institute of Neurology. "To me as a neuroscientist it's almost surreal."

Hardy, whose research work focuses on Alzheimer's and other types of dementia, said having women in an Olympic boxing ring was "a terrible thing" - not because he thinks women should not compete alongside men in sport, but because women boxing simply meant more people inflicting more damage on more brains.

That, in turn, was highly likely to mean more people suffering the devastating, incurable symptoms of brain diseases such as Alzheimer's.

Advances in modern neuroscience mean scientists know more than ever about chronic brain damage and the long-term trauma that can result from frequent knocks to the head.

"You get tiny lesions along the blood vessels where they have torn the nerve cells around them. This damages those nerve cells, and those cells start to develop the tangles that you see in Alzheimer's disease," Hardy said.

"And what we now understand is that this process spreads."

Partly due to this new understanding, now is a time of intense sensitivity about and scrutiny of brain damage in sport - particularly among North America's National Football League (NFL) players.

Former San Diego Chargers player Junior Seau committed suicide last year after what some believe were years of depression stemming from multiple concussions he suffered as a player.

Last week, the NFL and General Electric Co announced a $60-million effort with leading neurologists to speed up research on brain injury to improve diagnosis and treatment amid growing concern about sports-related concussion.

RULE CHANGES

A study published last year found that even minor repeated head blows during sports such as hockey and American football may damage the learning ability of sports men and women after just one season.

The brain debate has even reached the White House, where President Barack Obama suggested in January that changes be made to NFL rules to reduce the level of violent impact.

In soccer too, concerns are growing about the damage players might be doing to their brains when they head the ball.

A small study of female soccer players published last month found evidence of mental impairment caused by repeatedly bouncing a football off the head. The U.S. researchers who conducted that study said the effects suggested headers caused "mild traumatic brain injury of the frontal lobes".

When it comes to boxing, health experts and scientists - and even some competitors themselves - have been worried about brains for decades.

The Irish former featherweight world champion Barry McGuigan, perhaps fearful of what damage might already have been done, said in 1988: "Boxing damages your brain; don't let anyone tell you any different".

Around the same time, fellow lightweight fighter Terry Marsh, who was later diagnosed with epilepsy, said: "I don't need the British Medical Association to tell me getting hit on the head can't do me any good."

As far back as 1928, the American pathologist Harrison Stanford Martland wrote a paper entitled "Punch drunk" in which he showed that prize fighters were suffering from brain injury caused by the rupture of blood vessels.

The "punch drunk" condition, known more formally as chronic traumatic encephalopathy (CTE) or as its variants, dementia pugilistica or boxer's dementia, is a neurodegenerative disease that can affect boxers and others who suffer knocks to the head.

It can cause depression, aggression, impulsivity and memory loss and has been linked to suicide.

"A lot of boxers, and indeed American footballers too, have a period in their 30s and 40s where they are depressed, they drink, they show explosive tempers, and have basically pretty messed up lives," said Hardy.

BAD JUDGEMENT

It is not hard to find examples of boxers whose brains have begun to fail them.

American heavyweight champion and boxing idol Muhammad Ali began struggling with a stutter and trembling hands even before he came to the end of his fighting career. His subsequent decline with the neurodegenerative disorder Parkinson's syndrome has been painful for fans to witness.

Mike Tyson, a former undisputed heavyweight champion of the world, was convicted and imprisoned for rape, had multiple marriages and break ups, was declared bankrupt and was eventually diagnosed with the brain condition bipolar disorder.

British former heavyweight world champion Frank Bruno was diagnosed with the same condition while his compatriot Michael Watson needed six brain operations and suffered lasting damage after being knocked down in a 1991 bout.

Hardy argues that there is a tendency to think of these problematic lives as par for the course for boxers - who were more likely than non-boxers to come from disadvantaged backgrounds and mix in unstable circles.

"But the truth is they have bad judgment because of the injuries to their brain," he said. In the language of brain science this was called "loss of executive control", he explained, "and this in itself is part of the disease process".

"It's not inherent in their personalities as boxers, it's damage to the frontal cortex. They are already experiencing brain injury."

In an article posted on the World Boxing Association's (WBA) website, Calvin Inalsingh, head of the association's medical advisory committee, admits that "boxing is the only sport in which the objective is to render blows to the head and body of the opponent so as the cause the opponent to be incapacitated".

It is this, according to Hardy, that means when it comes to arguing for a ban on sports that cause brain injury, boxing is in a class of its own.

In other sports, such as American football, soccer or rugby, where the objective is to score touchdowns or goals or tries, and where head injury may be a by-product of that aim, authorities can and do change the rules or adjust the advice on protective clothing to make the game safer.

"But the whole point of boxing is to inflict brain damage," said Hardy. "That's why I think it's really a hopeless case in terms of a sport."

He has little doubt that in time, as medical knowledge expands, boxing will be banned, although he accepts there may be many more years of argument between brain scientists and sports authorities first.

"In science we have become very good at identifying causes and mechanisms of disease but unfortunately we understand things for a long time before we get better at solving them."
