Sony bringing PSP Go! October 1 for $249 in North America

Can you even believe it? Yeah, so, not a big secret, but at least we know that Sony is really bringing out a much smaller version of their portable console with the PSP Go!

We heard from Sony at its E3 press conference that it won't "replace" the PSP-3000 or UMD, it's 50 percent smaller and 40 percent lighter than the original PSP. All future retail titles will have retail and PlayStation store release. Japan can look for it Nov. 1 for ¥26,800.

Sony announces new PS3 motion controller

Sony just announced the rumored new motion controller for the PS3 -- the prototype looks like a wand with a color-changing ball on top. It's designed to work in conjunction with the PlayStation Eye, with the wand overlaid on-screen with a weapon or tool. Unlike Microsoft's Project Natal, Sony says they've learned "some experiences need buttons," which is why there's still a controller involved. The system is said to be "sub-millimeter" precise, and it was demoed drawing and playing a shooter -- it's sort of the middle ground between Natal and Wii Motion Plus. Sony says it'll launch in the spring of 2010, but we don't know what pricing will be like yet.

Stop Doing Sit-Ups: Why Crunches Don't Work

Everyone knows that the road to flat, tight abs is paved with crunches. Lots and lots and lots of excruciating crunches. Or is it?

As it turns out, the exercises synonymous with strong, attractive abs may not be the best way to train your core—and may be doing damage to your back.

“We stopped teaching people to do crunches a long, long time ago,” says Dr. Richard Guyer, president of the Texas Back Institute. That’s because the “full flex” movement—the actual “crunch” part of crunches – puts an unhealthy strain on your back at its weakest point. The section with the most nerves (and most potential for nerve damage) is in the back of the spine, which is the very part that bends and strains during a sit-up.

“There are only so many bends or a ‘fatigue life’,” in your spinal disks,” says Stuart M. McGill, a professor of spine biomechanics at the University of Waterloo. Inside each disk is a mucus-like nucleus, he says, and “if you keep flexing your spine and bending the disk over and over again, that nucleus slowly breaches the layers and causes a disk bulge, or a disk herniation.” A herniated disk won’t show through your swimsuit, but it’s no fun, and can cause persistent back and leg pain, weakness, and tingling.

Think of the oft-repeated advice for movers: bend at the hips and lift with your legs, not your back. And what is a sit-up but a back bend done in a lying position? “When people are doing curl up over gym balls and sit-ups, and this kind of thing, they are replicating a very potent injury mechanism on their back,” says McGill. “Every time they bend it they are one repetition closer to damaging the disk.”

And of course, when people do crunches, they rarely stop at one or two: in the quest for flat abs, they’ll churn out dozens at a time, bringing them ever closer to “flex intolerance”—so much pain and stiffness that it’s difficult to tie one’s shoes or bend down to pick a penny off the ground.

But who cares about back health as bathing suit season approaches? Turns out, crunches might not be the best solution for a flat stomach, either. That’s because doing too many sit-ups at the expense of other, more comprehensive movements can lead to the dreaded “aerobic abs.” That’s the term celebrity trainer Steve Maresca coined to describe the distended stomachs of those who focus only on the rectus abdominus muscles targeted by sit-ups and crunches. “They look great from the front, but when they turn to the side, their stomachs are extended,” he says. To get the long, lean look, one needs to work transverse abdominius, a large muscle that holds in those rectus abs, and is mainly unchallenged by traditional ab work (aka, the sit-up and crunches).

Doing a sit-up doesn’t train your ab muscles to do the job for which they were designed – keeping your spine straight and secure and providing power for your movements. In everyday life, “the abdominals are braces,” says McGill, author of "Ultimate Back Fitness and Performance" (Stuart McGill, 2004). When doing any athletic movement—even opening a door—“the spine is in a neutral posture, not flexed, and the abdominal muscles are contracted to brace the spine.”

The best way—for both your back and your beach body—to work your midsection is to do movements that challenge the muscles to perform the way they're designed and expected to work in real life, and not to train muscles in isolation. “It’s important to have strong abs, but strong abdominals are not the only thing,” says Dr. Guyer. “You have your back extenders, your flexors, which are belly muscles, you have your oblique muscles.” Working all of these muscle groups—the anatomical association known as “the core”—is essential to both back health and general athleticism.

As a result, only training for good-looking abs won’t add to your athleticism or overall strength. On the other hand, moves not traditionally designed for good-looking abs can in fact help strengthen and tone those muscles.

Consider the pushup. Not usually thought of as a great ab move, the pushup forces you to work several muscles at once: it forces your core muscles to stabilize your trunk as your arms and back work to move the body up and down. “Do you see how a pushup is a full body challenge?” says McGill. “It challenges abdominals, front of your legs, your arms and your back. That is how you use those muscles in real life.”

Like the pushup, the best exercises for back health and a firmer stomach are ones that work your abs while holding your spine straight, like planks or leg drops (done when you lie flat on your back, with your hands at the base of your spine for added support. Raise your legs up at a 90 degree angle, then slowly lower until they’re only inches from the ground. Repeat until your stomach burns and you want to throw up). And because your core is the center of power for most other exercises, a long workout full of dynamic movements targeting legs, arms and back also translates to a good core workout. (For more examples of effective ab exercises, visit McGill’s site, backfitpro.com.)

Of course, it won’t matter how muscular your torso is if your body fat is too high. The best way to build strong, visible abs isn’t through repeated sit-ups, but by engaging in circuit training that has you working your entire core while you’re burning calories – and to keep yourself disciplined during meals. “If you want to burn your fat mass, make sure you have a combination of weight training and cardiovascular, but 90 percent of good abs is your nutrition,” says Maresca. However, he does offer a quick tip for those of us with a weakness for caloric food: standing up straight and pulling back your shoulders will instantly tighten your transverse abdominal muscle, making you look a little leaner. It’s not quite as impressive as showcasing a well-developed core via 10 percent body fat, but it does leave a lot more time and flexibility for hitting up happy hour.

Homeopathy kills

This post may upset some people. It damn sure upset me. If you are easily upset by pediatric medical stories that do not end well, then you might want to skip reading this. The title alone may be all you need to know.]

Homeopathy is the antiscientific belief that infinitely diluted medicine in water can cure various ailments. It’s perhaps the most ridiculous of all "alternative" medicines, since it clearly cannot work, does not work, and has been tested repeatedly and shown to be useless.

And for those who ask, "what’s the harm?", you may direct your question to Thomas Sam and his wife Manju Sam, whose nine-month-old daughter died because of their homeopathic beliefs.

The infant girl, Gloria Thomas, died of complications due to eczema. Eczema. This is an easily-treatable skin condition (the treatments don’t cure eczema but do manage it), but that treatment was withheld from the baby girl by her parents, who rejected the advice of doctors and instead used homeopathic treatments. The baby’s condition got worse, with her skin covered in rashes and open cracks. These cracks let in germs which her tiny body had difficulty fighting off. She became undernourished as she used all her nutrients to fight infections instead of for growth and the other normal body functions of an infant. She was constantly sick and in pain, but her parents stuck with homeopathy. When the baby girl developed an eye infection, her parents finally took her to a hospital, but it was far too late: little Gloria Thomas succumbed to septicemia from the infection.

Thomas and Manju Sam were convicted yesterday of manslaughter in Australian court. As a parent myself I cannot even begin to imagine the pain they are going through, the anguish and the emotional horror. But let us be clear here: their belief in a clearly wrong antiscientific medical practice killed their baby. Homeopathy doesn’t work, but because they were raised in an environment that supports belief in homeopathy, they trusted it. They used it, and they rejected real, science-based medicine. And their daughter suffered the consequences.

And suffer she did. The accounts of the pediatricians who tried too late to help little Gloria Thomas are simply harrowing.

Every time I hear about something like this — a baby dying due to "alternative" medicine, or the lies and disinformation from the antivaccination movement, or some other belief system that flies in the face of reality — a little bit of me dies as well. I held my daughter shortly after she was born, and I would have done anything to protect her, and that included and still includes protecting her against people who fight so adamantly against reality.

The reality is that the antivaxxers’ work will result in babies dying. The reality is that belief in homeopathy will result in more babies dying. The reality is that denying science-based medicine will result in more babies dying.

And I know these words will fall on many deaf ears. And I will guarantee the comments to this post will contain many loud and irrational arguments supporting homeopathy and the antivaxxers. I’ve seen it before, and I know that many of those people are completely immune to reason and logic. And if you wonder what might wake them up, the answer may very well be nothing. Just read what Gloria Thomas’ father — the man just convicted of the manslaughter of his own daughter — had to say:

But even after Gloria died, Thomas Sam adhered to his belief that homeopathy was equally valid to conventional medicine for the treatment of eczema.

He told police: “Conventional medicine would have prolonged her life … with more misery. It’s not going to cure her and that’s what I strongly believe.”

He and his wife face 25 years in jail, where they will have plenty of time to rethink their convictions.

50 Beautiful Hand-Drawn Web Design

Most web designs starts off with a pen and paper before its taken over by Photoshop. However, we’ve noticed a new trend (probably not too new) where designers are bringing back sketches as a form of design. Without a doubt, hand-drawn art is one of the popular styles adopted into web designs. Nothing is better than using these sketchy designs to convey and reflect individual styles.

In this post, we’d like to show you 50 great examples of how hand drawing and web design can fit beautifully together. Full list after jump.
