A pace motorcycle stalled moments into 30k Red Hook Crit bike race, forcing dozens of cyclists into a gnarly pileup just as they were reaching sprint speed on their fixed-gear bikes. A few managed to dodge the motorcycle until they didn’t, and mayhem ensued.
The crash forced a restart of the 85-rider race, and apparently went off as normal on the mulligan, after a short delay to mourn the dead truck survivors to the hospital. Cycling reporter Daniel McMahon, who was on the scene, tweeted later that seven riders suffered non-life-threatening injuries.
Now that you know you don’t have to feel guilty watching this melee, here’s how it looked from a cyclist’s perspective:
Sometimes all we need is a little distance to fully realize the ridiculousness of the world we live in. That’s exactly what happens when you watch this video about the gym that’s been filmed like a wildlife documentary, complete with a Morgan Freeman-like voiceover. At six minutes, the video is a little long—and the Internet has done wonders to our attention spans—so if you only have time for the highlights, fast forward to these gems:
Resveratrol was seen to improve physical performance, heart function and muscle strength in the same way as they’re improved after a gym session.
According to lead researcher, Jason Dyck, these findings will particularly help those who are unable to exercise. Discussion over the health benefits of red wine have been well documented. Studies have revealed that those who drink a glass of red wine a day are less likely to develop dementia or cancer, that it’s good for your heart, anti-ageing and can regulate blood sugar.

Some forms of exercise may be much more effective than others at bulking up the brain, according to a remarkable new study in rats. For the first time, scientists compared head-to-head the neurological impacts of different types of exercise: running, weight training and high-intensity interval training. The surprising results suggest that going hard may not be the best option for long-term brain health.
As I have often written, exercise changes the structure and function of the brain. Studies in animals and people have shown that physical activity generally increases brain volume and can reduce the number and size of age-related holes in the brain’s white and gray matter.
Exercise also, and perhaps most resonantly, augments adult neurogenesis, which is the creation of new brain cells in an already mature brain. In studies with animals, exercise, in the form of running wheels or treadmills, has been found to double or even triple the number of new neurons that appear afterward in the animals’ hippocampus, a key area of the brain for learning and memory, compared to the brains of animals that remain sedentary. Scientists believe that exercise has similar impacts on the human hippocampus.

These past studies of exercise and neurogenesis understandably have focused on distance running. Lab rodents know how to run. But whether other forms of exercise likewise prompt increases in neurogenesis has been unknown and is an issue of increasing interest, given the growing popularity of workouts such as weight training and high-intensity intervals.
So for the new study, which was published this month in the Journal of Physiology, researchers at the University of Jyvaskyla in Finland and other institutions gathered a large group of adult male rats. The researchers injected the rats with a substance that marks new brain cells and then set groups of them to an array of different workouts, with one group remaining sedentary to serve as controls.
Some of the animals were given running wheels in their cages, allowing them to run at will. Most jogged moderately every day for several miles, although individual mileage varied.
Others began resistance training, which for rats involves climbing a wall with tiny weights attached to their tails.
Still others took up the rodent equivalent of high-intensity interval training. For this regimen, the animals were placed on little treadmills and required to sprint at a very rapid and strenuous pace for three minutes, followed by two minutes of slow skittering, with the entire sequence repeated twice more, for a total of 15 minutes of running.
These routines continued for seven weeks, after which the researchers microscopically examined brain tissue from the hippocampus of each animal.
They found very different levels of neurogenesis, depending on how each animal had exercised.
Those rats that had jogged on wheels showed robust levels of neurogenesis. Their hippocampal tissue teemed with new neurons, far more than in the brains of the sedentary animals. The greater the distance that a runner had covered during the experiment, the more new cells its brain now contained.
There were far fewer new neurons in the brains of the animals that had completed high-intensity interval training. They showed somewhat higher amounts than in the sedentary animals but far less than in the distance runners.
And the weight-training rats, although they were much stronger at the end of the experiment than they had been at the start, showed no discernible augmentation of neurogenesis. Their hippocampal tissue looked just like that of the animals that had not exercised at all.
Obviously, rats are not people. But the implications of these findings are provocative. They suggest, said Miriam Nokia, a research fellow at the University of Jyvaskyla who led the study, that “sustained aerobic exercise might be most beneficial for brain health also in humans.”
Just why distance running was so much more potent at promoting neurogenesis than the other workouts is not clear, although Dr. Nokia and her colleagues speculate that distance running stimulates the release of a particular substance in the brain known as brain-derived neurotrophic factor that is known to regulate neurogenesis. The more miles an animal runs, the more B.D.N.F. it produces.
Weight training, on the other hand, while extremely beneficial for muscular health, has previously been shown to have little effect on the body’s levels of B.D.N.F., Dr. Nokia said, which could explain why it did not contribute to increased neurogenesis in this study.
As for high-intensity interval training, its potential brain benefits may be undercut by its very intensity, Dr. Nokia said. It is, by intent, much more physiologically draining and stressful than moderate running, and “stress tends to decrease adult hippocampal neurogenesis,” she said.
These results do not mean, however, that only running and similar moderate endurance workouts strengthen the brain, Dr. Nokia said. Those activities do seem to prompt the most neurogenesis in the hippocampus. But weight training and high-intensity intervals probably lead to different types of changes elsewhere in the brain. They might, for instance, encourage the creation of additional blood vessels or new connections between brain cells or between different parts of the brain.
So if you currently weight train or exclusively work out with intense intervals, continue. But perhaps also thread in an occasional run or bike ride for the sake of your hippocampal health.
About 15 years ago, I was invited to join a knitting group. My reluctant response — “When would I do that?” — was rejoined with “Monday afternoons at 4,” at a friend’s home not three minutes’ walk from my own. I agreed to give it a try.
My mother had taught me to knit at 15, and I knitted in class throughout college and for a few years thereafter. Then decades passed without my touching a knitting needle. But within two Mondays in the group, I was hooked, not only on knitting but also on crocheting, and I was on my way to becoming a highly productive crafter.
I’ve made countless afghans, baby blankets, sweaters, vests, shawls, scarves, hats, mittens, caps for newborns and two bedspreads. I take a yarn project with me everywhere, especially when I have to sit still and listen. As I’d discovered in college, when my hands are busy, my mind stays focused on the here and now.
It seems, too, that I’m part of a national resurgence of interest in needle and other handicrafts, and not just among old grannies like me. The Craft Yarn Council reports that a third of women ages 25 to 35 now knit or crochet. Even men and schoolchildren are swelling the ranks, among them my friend’s three grandsons, ages 6, 7 and 9.
Last April, the council created a “Stitch Away Stress” campaign in honor of National Stress Awareness Month. Dr. Herbert Benson, a pioneer in mind/body medicine and author of “The Relaxation Response,” says that the repetitive action of needlework can induce a relaxed state like that associated with meditation and yoga. Once you get beyond the initial learning curve, knitting and crocheting can lower heart rate and blood pressure and reduce harmful blood levels of the stress hormone cortisol.
But unlike meditation, craft activities result in tangible and often useful products that can enhance self-esteem. I keep photos of my singular accomplishments on my cellphone to boost my spirits when needed.
Since the 1990s, the council has surveyed hundreds of thousands of knitters and crocheters, who routinely list stress relief and creative fulfillment as the activities’ main benefits. Among them is the father of a prematurely born daughter who reported that during the baby’s five weeks in the neonatal intensive care unit, “learning how to knit preemie hats gave me a sense of purpose during a time that I felt very helpless. It’s a hobby that I’ve stuck with, and it continues to help me cope with stress at work, provide a sense of order in hectic days, and allows my brain time to solve problems.”
A recent email from the yarn company Red Heart titled “Health Benefits of Crocheting and Knitting” prompted me to explore what else might be known about the health value of activities like knitting. My research revealed that the rewards go well beyond replacing stress and anxiety with the satisfaction of creation.
For example, Karen Zila Hayes, a life coach in Toronto, conducts knitting therapy programs, including Knit to Quit to help smokers give up the habit, and Knit to Heal for people coping with health crises, like a cancer diagnosis or serious illness of a family member. Schools and prisons with craft programs report that they have a calming effect and enhance social skills. And having to follow instructions on complex craft projects can improve children’s math skills.
Some people find that craftwork helps them control their weight. Just as it is challenging to smoke while knitting, when hands are holding needles and hooks, there’s less snacking and mindless eating out of boredom.
I’ve found that my handiwork with yarn has helped my arthritic fingers remain more dexterous as I age. A woman encouraged to try knitting and crocheting after developing an autoimmune disease that caused a lot of hand pain reported on the Craft Yarn Council site that her hands are now less stiff and painful.
A 2009 University of British Columbia study of 38 women with the eating disorder anorexia nervosa who were taught to knit found that learning the craft led to significant improvements. Seventy-four percent of the women said the activity lessened their fears and kept them from ruminating about their problem.
Betsan Corkhill, a wellness coach in Bath, England, and author of the book “Knit for Health & Wellness,” established a website, Stitchlinks, to explore the value of what she calls therapeutic knitting. Among her respondents, 54 percent of those who were clinically depressed said that knitting made them feel happy or very happy. In a study of 60 self-selected people with chronic pain, Ms. Corkhill and colleagues reported that knitting enabled them to redirect their focus, reducing their awareness of pain. She suggested that the brain can process just so much at once, and that activities like knitting and crocheting make it harder for the brain to register pain signals. More of Stitchlinks findings are available at their website.
Perhaps most exciting is research that suggests that crafts like knitting and crocheting may help to stave off a decline in brain function with age. In a 2011 study, researchers led by Dr. Yonas E. Geda, a psychiatrist at the Mayo Clinic in Rochester, Minn., interviewed a random sample of 1,321 people ages 70 to 89, most of whom were cognitively normal, about the cognitive activities they engaged in late in life. The study, published in the Journal of Neuropsychiatry & Clinical Neurosciences, found that those who engaged in crafts like knitting and crocheting had a diminished chance of developing mild cognitive impairment and memory loss.
Although it is possible that only people who are cognitively healthy would pursue such activities, those who read newspapers or magazines or played music did not show similar benefits. The researchers speculate that craft activities promote the development of neural pathways in the brain that help to maintain cognitive health.
In support of that suggestion, a 2014 study by Denise C. Park of the University of Texas at Dallas and colleagues demonstrated that learning to quilt or do digital photography enhanced memory function in older adults. Those who engaged in activities that were not intellectually challenging, either in a social group or alone, did not show such improvements.
Given that sustained social contacts have been shown to support health and longevity, those wishing to maximize the health value of crafts might consider joining a group of like-minded folks. I for one try not to miss a single weekly meeting of my knitting group.
Okay, I’ll be honest. I would rather own a dog than a cat. It’s not like I don’t like cats. It’s just that in my experience, dogs seem to be a whole lot friendlier and loyal.
Well, I recently came across a series of pictures from Lingvistov that illustrate why there are so many benefits to having a cat. And let me tell you, they’re absolutely fabulous. Of course, some of these benefits aren’t real benefits, but you can’t argue with how adorable the cats look in each of these pictures!

While they may not be as unintentionally disturbing as those Darth Vader and Stormtrooper porch light covers, there’s something a little unsettling about these Star Wars shower heads.
Sure, they’re cool and all, but R2-D2 and Darth Vader just lurk there, staring, as you scrub your body. Now, we know Artoo can keep secrets: He’s seen things, and not even uttered a beep or a whirl to C-3PO. But Vader? He just watches with that hollow-eyed gaze as he rains down angry water and wonders where his tormented life went wrong.
