Galaxies Go Wild
The Hubble Space Telescope has captured stunning images of colliding galaxies, which have been released to mark the 18th anniversary of the telescope's launch.
The dramatic collisions trigger bursts of star formation and sometimes result in new galaxies.

The Top Medical Myths

HAVING SEX CAN CAUSE A HEART ATTACK IN MEN
How wrong is this? Fairly. The risk is hugely exaggerated by the familiar portrayals of men in books, films and dramas gasping their last in flagrante.
What are the facts? Research shows that the chances of a 50-year-old non-smoking male suffering a heart attack is about one in a million in any hour. Having sex increases these odds to two in a million, but doubling a barely existent risk means that risk is still negligible.
Any related myths? That sex is a form of exercise. In fact, it equates only to climbing two flights of stairs.
HIGH BLOOD PRESSURE CAUSES HEADACHES
How wrong is this? Very. An astronomically high blood pressure might cause a headache, but this is rare.
What are the facts? High blood pressure (hypertension) usually has no symptoms at all. It's not a disease, it's a risk factor, so it is treated to reduce your chances of a future stroke or heart attack, not too make you feel better.
Any related myths? That high blood pressure causes dizziness. No, dizzyness is a side-effect of the treatment.
DIABETICS CRAVE SUGAR
How wrong is this? Fairly. Diabetics do have to alter their sugar intake and they sometimes require an urgent sugar fix if their blood glucose is too low. So concluding that craving sugar equals diabetes is understandable but wrong.
What are the facts? Diabetes isn't caused by excess sugar, it's simply that the diabetic body has problems handling it.
Any related myths? That diabetics need to buy special, low-sugar versions of food and drink. They don't - a simple healthy diet will suffice.
WOMEN NEED TO EXAMINE THEIR BREASTS
How wrong is this? Very.
What are the facts? Research shows that routine self-examination does no good in terms of breast cancer outcomes because it isn't sensitive enough to detect important lumps. In fact, it can actually cause harm. How? By subjecting self-examiners to increased levels of anxiety.
Any related myths? There is an exact parallel with routine self-examination of testicles in males - another discredited activity that continues to receive publicity because it sounds like a good idea.
DIETS CUT CHOLESTEROL
How wrong is this? Fairly. Doctors rarely suggest diet alone if your cholesterol really needs lowering.
What are the facts? A healthy diet's a good idea. But if you want lower cholesterol, you'll probably be disappointed. Because, even in trials, the best that's achieved is a 10 per cent reduction. Most cholesterol is made by your liver, with your dietary intake contributing little. Cholesterol is usually treated with statins.
Any related myths? That a high cholesterol is a cause for panic - it's simply a risk factor, like high blood pressure, for future problems.
HEADACHES ALONE CAN BE A SIGN OF A BRAIN TUMOUR
How wrong is this? Totally.
What are the facts? The stats alone may be ease your headache. After all, your GP sees this symptom daily, but encounters a brain tumour only a few times in his entire career. Nasties of this sort almost always produce other symptoms - fits, personality change or unsteadiness.
Any related myths? That a scan is a good idea. The chances of turning up an irrelevant but worrying abnormality are fairly high.
YOU SHOULDN'T MIX ANTIBIOTICS AND ALCOHOL
How wrong is this? Totally, with the exception of the antibiotic metronidazole.
What are the facts? Any interaction of alcohol with virtually all antibiotics is nonexistent, or so small as to be irrelevant. Metronidazole, an antibiotic used for a variety of infections, is the exception to this rule. When mixed with even small amounts of booze, it causes vomiting.
Any related myths? That you should always finish your course of antibiotics. It usually makes little difference.
YOUR TIREDNESS MAY BE CAUSED BY ANAEMIA
How wrong is this? Fairly.
What are the facts? Tiredness is common and, in the absence of other symptoms, is usually caused by lifestyle issues such as stress and lack of exercise. Mild anaemia caused by iron deficiency is common, too, particularly in women. As tiredness often prompts a blood test, it's common for anaemia to be revealed, and assumed wrongly to be the cause.
Any related myths? That tiredness will be solved by vitamins - though the chemist might tell you otherwise.
FLU JABS GIVE YOU FLU
How wrong is this? Totally. You might suffer a sore arm or, at most, a slight fever.
What are the facts? The vaccine does not contain live germs and so cannot cause flu. But, as it's given in autumn, peak snuffle period, many patients will pick up a virus around the time of their jab. This they misinterpret as flu, which they link to the jab.
Any related myths? The idea that if you are healthy, the flu jab isn't necessary. In fact, it's recommended to all over-65s, even if they're fit and well.

5 Psychological Experiemnts That Prove Mankind is Doomed!
The Setup:
Solomon Asch wanted to run a series of studies that would document the power of conformity, for the purpose of depressing everyone who would ever read the results.
The Result:
Questions the subjects were asked were like the puzzle shown here:
All they had to do was say which line on the right matched the one on the left. As you can see, Asch wasn't exactly asking these people to design the next space station. Really, the only way you could get the line questions honestly wrong is if you took two doses of LSD that morning and rubbed them directly on your eyeballs (which would have made for an even more awesome experiment, but we're getting off the point).
Yet, sadly, 32 percent of subjects would answer incorrectly if they saw that three others in the classroom gave the same wrong answer. Even when the line was plainly off by a few inches, it didn't matter. One in three would follow the group right off the proverbial cliff.
What This Says About You:
Imagine how much that 32 percent figure inflates when the answers are less black and white. We all tend to laugh with the group even when we didn't get the joke, or doubt our opinion we realize ours is unpopular among our group. So much for those lectures you got in elementary school about peer pressure and "being brave enough to be yourself."
"Well, it's a good thing I'm a rebellious non-conformist," many of you are saying. Of course, for virtually all of you, the next step is to find out what the other non-conformists are doing ...
The Biblical story of the Good Samaritan, if you hadn't heard, is about a passing Samaritan helping an injured man in need, while other, self-righteous types walk right on by. Psychologists John Darley and C. Daniel Batson wanted to test if religion has any effect on helpful behavior.
As an extra twist, subjects were given different times that they had to deliver the sermon so that some would be in a hurry and others not.
Then, on the way to the building, subjects would pass a person slumped in an alleyway, who looked to be in need of help. We like to think Darley and Batson beat the crap out of some random dude to make it more realistic, but sources say otherwise.
C. Daniel Batson probably did not beat a homeless dude
The people who had been studying the Good Samaritan story did not stop any more often than the ones preparing for a speech on job opportunities. The factor that really seemed to make a difference was how much of a hurry the students were in.
What This Says About You:
And in case you thought these results were just restricted to hypocritical seminary students, turn on the news. Remember a few years ago when cameras captured at least a dozen cars refusing to stop for an injured woman laying in the road?
Which brings us to ...
When a woman was murdered in 1964, newspapers printed that 38 people had heard and seen the attack, but did nothing. John Darley and Bibb Latane wanted to know if the fact that these people were in a large group played any role in the reluctance to come to aid.
The two psychologists invited volunteers to take part in a discussion. They claimed that because the discussion would be extremely personal (probably asking about the size of their genitals or something) individuals would be separated in different rooms and talk to each other using an intercom.
When subjects believed that they were the only other person in the discussion, 85 percent were heroic enough to leave the room and seek help once the other began the fake seizure. This makes sense. Having an extremely personal conversation (again, presumably about tiny genitalia) with another person is difficult enough, but being forced to continue to carry on the conversation by yourself is just sad. But either way, 85 percent helped. So that's good, right?
Anyone can have epilepsy, according to this child's drawing
What This Says About You:
Obviously if there's an emergency and you're the only one around, the pressure to help out increases massively. You feel 100 percent responsible for what happens. But, when you're with 10 other people, you're only 10 percent as responsible. The problem is everybody else only feels 10 percent responsible too.
Or maybe it comes down to just how plausible an excuse we can make for ourselves. "Surely someone will come along and save the lady in the road," we say. Or, "Surely someone else will do something about the environment," or "Surely the shark will get full and stop eating that dude at some point." We just need the slightest excuse to do nothing.
#2. The Stanford Prison Experiment (1971)
The Setup:
Psychologist Philip Zimbardo wanted to find out how captivity affects authorities and inmates in prison. Sounds innocent enough. Seriously, what could go wrong?
Not the actual ad
Yep, nothing at all can go wrong with this.
The Result:
Incredibly, when "prisoners" were told they had a chance at parole, and then the parole was denied, it didn't occur to them to simply ask out of the damned experiment. Remember they had absolutely no legal reason to be imprisoned, it was just a damned role-playing exercise. This fact continued to escape them as they sat naked in their own filth, with bags on their heads.
What This Says About You:
Ever been harassed by a cop who acted like a major douchebag, pushing you around for no reason? Science says that if the roles were reversed, you'd likely act the same way.
When the prosecution of the Nazis got underway at the Nuremberg Trials, many of the defendants' excuse seemed to revolve around the ideas of, "I'm not really a prick" and, "Hey man, I was just following orders." Yale University psychologist Stanley Milgram wanted to test willingness of subjects to obey an authority figure. Maybe he could just, you know, ask people? Oh, hell no. That would not be nearly horrifying enough.
The subject was told that whenever the other guy gave an incorrect answer, he was to press a button that would give him an electric shock. A guy in a lab coat was there to make sure he did it (again no real shock was being delivered, but the subject of course did not know this).
So, can you guess how this went?
The Result:
Many subjects began to feel uncomfortable after a certain point, and questioned continuing the experiment. However, each time the guy in the lab coat encouraged them to continue. Most of them did, upping the voltage, delivering shock after shock while the victim screamed. Many subjects would laugh nervously, because laughter is the best medicine when pumping electrical currents through another person's body.
Five percent? Ten?
What This Says About You:
You might like to think of yourself as a free-thinking marauder, but when it comes down to it, odds are you won't stick it to The Man because of the fear The Man will stick it right back up your ass. And this was just a guy in a lab coat--imagine if he'd had a uniform, or a badge.
Almost 80 percent. Think about that when you're walking around the mall: Eight out of ten of those people you see would torture the shit out of a puppy if a dude in a lab coat asked them to.
