Sweating: good for you and good for your performance

pre-Christmas 2015 run in the dreary dead of winter
(note trees) -- except it was 71 deg F/ 22 deg C!
I was not expecting to go running on Christmas Eve 2015 in shorts and a tank top and return as sweaty as if it were a warm summer's day.

But it was nearly that, at 71 degrees F (22 degrees C), record-breaking for Washington, DC (average December 24th temperature is 30 degrees cooler!). Crazy.

Not only that, my little GPS watch showed that my pace was far faster than I'd expected (5:20/km or 8:35/mi in what was supposed to be an easy run), supporting the idea that sweating helps improve athletic performance, on top of keeping you cool in hot weather.

Historically not a major concern in winter, sweating is generally good for us as we exercise.

Sweating is our body's means of staying cool. Eccrine sweat glands, found all over our body, produce clear, odorless fluid that is basically water + salts. As the water evaporates off our skin, we feel cooler (and saltier).

Hidden gems: pygmy seahorses' beautiful camouflage

In the search for interesting behaviors and traits that help species survive and reproduce successfully, to improve their biological fitness, seahorses seem to come up frequently!

These traits get crazier with the pygmy seahorse. These little guys have a single gill that opens on the back of their head (all other seahorses have a pair of gill openings either side of the head) and the young develop within the male's trunk, rather than a pouch on the tail

Residents of the western Pacific Ocean, pygmy seahorses are usually less than 2 cm long and thus rely on perfect camouflage to survive.  So here's a question:

Do they search for a coral that matches their color, or do they change their color to match the coral?

Find out in this video!

Bear with me...up the cliff


Bad-ass as a black bear - you haven't heard that expression before, since I just made it up, but here's why: You may know that black bears like to climb trees, but did you know that they are equally impressive at climbing cliffs?

Here are a mom and cub showing off their rock climbing skills -- scaling a sheer canyon cliff with no ropes, no equipment, and no help:


Stephanie Latimer filmed the pair of Mexican black bears climbing the wall of the Santa Elena Canyon wall in March of 2014. She says, "I spotted them while I was kayaking and want to share with you my nature loving, rock climbing, suspenseful satisfaction."

A few bare facts on bears

Black bears, like all bears, get hungry on a daily basis, especially when climbing canyons.

Yum, yum, pass me some more of that sweet vegetation.
Photo: Harvey Barrison, Wikimedia Commons
Like us, they are omnivores (they eat many types of foods) -- they munch on the tender grasses, buds, berries, tree roots, fish, insects, and bee honey in forests.

As the forests containing their natural sources of food disappear, they broaden their definition of food to include crops, campers' rations, and human garbage [Don't feed bears].

When food scarcity combines with cold snaps or prolonged bad weather, they may start searching human areas, including suburbs and even cities, in earnest.

They are curious, but don't look for trouble with people, though: according to data from the National Center for Health Statistics, "...for every person killed by a black bear in North America, 60 are killed by domestic dogs, 180 by bees, and 350 by lightning."

So marvel at bears' ability to run fast, climb, and snag fish with just their teeth -- from a distance.

Vultures: fit to feed on anything (so long as it's dead)

vulture cleaning service -- breaking down a carcass in Africa
Their ability to eat decaying animals makes vultures a critical part of maintaining the health of ecosystems everywhere.

Think for a moment about the smell and disease that would prevail without these birds and other scavengers providing their cleaning service for the rest of us.

When an animal dies, bacteria get their chance to start feeding on it, which boosts their fitness and, thus, their populations. Many bacteria also produce toxins that prevent larger animals from joining in the feast, but vultures just dig right in.

How do they do it?  Vultures and other scavengers detoxify their food either before or after eating, through "unusually destructive" stomach juices and gut bacteria. They also build up antibodies to the toxins found in decaying meat and appear to pass around small doses of the germs through their group interactions - like we do via vaccines.

This MinuteEarth video explains some of these fantastic, if somewhat gross, adaptations.


For their help in keeping our fields, prairies, and roads clean, we should give a cheer for the vultures.

Yet we are killing them. Lead in the gunshot remaining in animals that are shot and injured or just left by hunters poisons the scavengers, such as the majestic California condor, that eat these carcasses.

In Africa, where the poaching (illegal killing) of large animals, primarily elephants and rhinos, is exploding with unprecedented precision and ruthlessness, vultures are targeted and killed directly.

Vultures circle above dying and dead animals, which can signal rangers far away that an animal has been killed. By killing the tell-tale vultures, as well as the elephant, poachers hide their crime.

Persecution has made several African vulture species endangered, and their good looks haven't won them much appreciation from most people.

Yet their ability to digest poisons without getting the food poisoning that would sicken or even kill one of us is itself worth of respect and research. And by eating a food that others can't, they maintain a stable energy source.

More urgently for us, the importance of their daily activity to human and animal health is undeniable. Each piece of the ecological puzzle is important, and our fitness depends in part on theirs!

Low energy levels lead to high-calorie intake...and low productivity

Having just proven my previous research correct, I just finished a bunch of cake. Late at night. When my will power was (is) low.

Studies and personal experience confirm how much easier it is to resist processed and high-calorie foods in the supermarket than in your fridge.

I pretend that putting desserts in the freezer will hide them from me and I won't remember to go for them. Except late at night, when I just KNOW they are there and sometimes give in.

While I'm not the only person that does this, it's still frustrating to feel full with no real benefits from the intake.

The key to these lapses may be our pre-snack energy levels because self-control requires energy (this downloads a PDF).

A dose (or two) of Nature

Doctor-recommended antidote to a whole host of office- and city-related ailments:


(and, of course, laughter is good for you too!)

According to a Harvard Med School review, various studies have found that people living near parks have fewer psychological problems than city residents who lack access to green spaces.

Trees are thought to improve our psychological, as well as our physical, health.

Visiting natural places has been shown to lower levels of stress hormones and lift our mood and decrease anxiety by literally changing our brain's functioning.  (scientific results here).

It also seems to improve our immune system and help us maintain focus.

Plus, walking or cycling through a local park or forest is often free!


So be safe, wear your sunscreen, take care with stormy weather, and discover (and support!) your local green spaces.

Here's mine -- Rock Creek Park (roughly 2,000 acres / 800 ha) in Washington, DC:

Bikes work, even when you don't!

To all you cyclists: do you know how bikes stay so stable?  How they can even remain upright without a rider?

A bike pushed forward at sufficient speed will continue moving steadily forward on its own.....but why?  This video from Minute Physics explains the forces behind how bikes can steer even without a rider.


Basically, the handlebars need to be loose enough to help compensate for uneven ground and for the lean of the bike in either direction off center.

"For a bicycle to be stable, the steering mechanism has to be unstable; if the bike falls, the steering should fall even more quickly," says Arend Schwab, a Professor at Univ. of Delft in The Netherlands.

A little quantitative, but fun and informative on a machine many of us use daily for the most mundane of tasks.  Enjoy!

of course!

When coral meets micro-algae

Scuba diving is like zen for me. I've been fortunate enough to watch the forms and fauna underwater, and nothing else is as relaxing as that. Many, many things are cheaper and easier, though, so I don't go often enough.

But coral reefs are more than meditation for lucky divers, they are homes to nearly 25% of all marine species -- they are "rainforests of the sea," if you will -- and the nurseries for many species of fish eaten by many of you out there.

They also protect seashores and islands, but more on that later.

Raise your hand if you know how these amazing structures are formed; everybody else can go ahead and read on!

Fresh produce is the best! Or is it?

Right now, in the United States, farmers' markets are now found not only near farms but also in urban centers.

It's the time of year where vegetables – sweet corn, peppers, tomatoes, and even especially zucchini – burst on the scene and flood markets everywhere, their freshness and flavor making their case for buying locally grown produce in its prime season.

What color is your Pepper? A Washington, DC farmers' market
6 – 7 different kinds of eggplants, among other goodies
If you are also buying fresh, local produce, keep it up and enjoy your good fortune.

However, in the off season, frozen veggies can actually be a better nutritional choice. Who knew?

True, with some simple caveats -- if the frozen fruits and veggies are picked when ripe and frozen immediately AND fresh food has been picked too early and taken weeks to arrive in your kitchen, then frozen vegetables may be the way to go, especially if their convenience means you will actually eat them.

Fresh vs Frozen?  The answer is YES, eat your veggies.

Armadillo armor!

Was it Karmadillo, as a friend of mine suggested?

Was it Armed-adillo, as I retorted?

That hard shell on a small armadillo in Texas may have served its protective purpose yesterday, as a bullet shot at it by a man ricocheted off the shell and back at the guy, wounding him in the face. The armadillo's crime was trespassing on the man's property.

Only in Texas, maybe? Apparently not -- a man in Georgia (yes, also the US) wounded his mother-in-law after the bullet he shot at an armadillo ricocheted and hit the poor lady. And sadly also killed the animal.

Beat ya.

Armadillos actually originated in South America, and the 20 living species all still reside there, some of which have since also moved north.

Armadillo means "the little armored one" in Spanish, though the Aztecs called them turtle-rabbits.

Their armor is made of rigid bony plates covered in relatively small, overlapping bony scales called "scutes", that are then covered by the material found in horns! Flexible skin separates the overlapping bands, which cover the animal's head, back, legs, and tail. The bendable nature of this skin allows some species to pull in their legs and roll up into their carapace. Not quite like a turtle, but the same idea.

Two armadillo species can roll into a tight ball to avoid being eaten, while others run from predators into burrows or thorny vegetation (where their outer protection comes in handy).

While the armor may help protect them from bullets, I would gather the protective carapace works a lot better against coyotes, bears, pumas, and alligators.

Home alone: mollusks build their shells from sea water

box turtle on the move.  Any minute now....
photo: Jonathan Zander, Wikimedia Commons
In warm summer months, many people travel across continents in mobile homes (a.k.a. campers or caravans), so they can visit new places and outdoor spaces with the convenience of always having their familiar nightly shelter nearby.

In nature, many critters just grow their own homes and carry them along. Not just turtles, but also snails and myriad species of shellfish carry their supportive structure on the outside.

Shells are actually the exoskeletons of various types of invertebrates (animals with no backbone), including snails, conch, clams, and oysters. Shells protect the soft mushy critter inside and give it structural support.

So where are the animals in all those shells we see on the beach?

What's small and resembles a hammerhead shark?

Pterosaurs are impressive but weak at flying backwards
image: Examiner
They pre-date dinosaurs and have evocative names that are nearly as cool as T-rex: hawkers, cruisers, chasers, emeralds, tigertails, petaltails, skimmers, and goldenrings are just a few.

Can you guess this creature?

They successfully capture their prey 95% of the time, making them perhaps the most successful predator we know.

They can instantly fly in any of 6 directions – up, down, forward, backward, left, right.

They can fly 30 mph (50kph) forward and 10 mph backward.

They can migrate across oceans.

Any ideas yet?

Did I mention they are about 1-4 inches (2.5-10 cm) long?

Fats come in many forms - use wisely

Low-fat?  No-fat?

Fats. They're like the Devil for many people trying to lose weight.

In our consumer economy, Low-Fat, Fat-Free, and Light options abound, never mind that the product now contains more sugar, flour, or thickeners to recreate some semblance of the texture and flavor of the original product.

Happily for all of us, recent research has shown that certain types of dietary fat can actually improve our health and has led to changes in nutritional guidelines for fats.

Coffee is good (and bad, but mostly good) for you!

Welcome to another Monday morning, and for many people, a fresh cup (or 2...) of coffee.

Which is actually a Good Thing: despite the guilty pleasure and bad reputation coffee has generated, there is growing consensus among medical researchers that drinking coffee improves, rather than harms our health and fitness.

Besides keeping you awake, coffee may provide an increasing number of potential health benefits, including protection against liver and colon cancer, type 2 diabetes, and Parkinson's disease, according to some recent scientific studies.

But there's also a downside: too much java can make you jittery and cause stomach pains, and some studies have tied it to elevated blood pressure and heart rates. Why the dichotomy?

Summer takeover

This is, of course, Australia, where killer critters abound
photo credit: Bill Adler, Flickr
It's the unofficial beginning of summer in the United States this weekend, and people are headed to the beach, so I figured a post on jellyfish would be appropriate.

Why?

They're brainless, boneless, and bloodless, and they mostly drift with the currents, but they are apparently scheming to take over the seas.

And we are helping them do it, by messing with fish communities, ocean temperatures, and chemical composition of the water itself.

Huh?

Nut nutrition, seeds that satisfy

man-eating plant
this one is still really hungry
photo: The AquaponicSource
Picture life as a plant. A brand new plant who's hungry and can't just go to the store for a snack.

How do you start growing with no one to feed you?

Happily, your loving mom endowed you with a nutritious snack when you said farewell and blew off or got carried away by some hungry animal.

That snack is made up of actual tissue from your mom, surrounding and even protecting you until you develop your own leaves and roots and start finding your own darned food through them. Thanks, Mom!

Once fertilized, the new plant embryo grows within a seed. Plants need food just as we do, and a seed provides the nutrients and energy used by a growing plant.

A seed, therefore, packs a lot of nutrition, particularly fats, proteins, and other plant nutrients, into a tiny compact package, that can also benefit a person or animal that eats it.

Strategic coffee - beer consumption

We recently learned how caffeine affects our brain and nervous system, keeping us alert and awake by blocking the compound adenosine from telling us we need to sleep and causing chemical reactions that increase brain activity.

In case that was too much to read or process, here's a simplified version that also suggests strategic consumption of both coffee and beer!  Perhaps happy hour needs to come BEFORE the workday, to help you generate new ideas, do better in your job, and thus improve your social and biological fitness.

Why we (and bees) crave coffee


OK, it's Monday, where's the coffee?

Why do so many people crave coffee first thing in the morning?

Yes, we need it to feel awake.  But why coffee?  Why not an egg roll?  Or some yogurt?

Because coffee, and not eggs or yogurt, contains caffeine, a substance that stimulates the human nervous system and makes it think the body is still full of energy. Yeah, I don't need sleep!

Caffeine, the kicker in coffee (and tea, and Coca Cola, etc) is a psychoactive drug, one that alters your brain function, temporarily changing your perception, mood, consciousness, and behavior. Many of these changes are helpful (e.g. that increased alertness that coffee brings on), and this positive reinforcement makes us depend on it.

Trees and priorities



As you breathe while reading this on your wireless device, consider the trees and other plants that take in carbon dioxide and breathe out oxygen to help you out. Our collective fitness literally depends on them continuing to do that!

Living trees and other plants help us in many other ways too, by creating cleaner, cooler, quieter environments for us and for other animals, who in turn pollinate plants, aerate soil, and generally keep Earth's terrestrial systems running. For those of us that eat food – of any sort – it's something to appreciate.

The light stuff: anglerfish brighten up the depths

goldfish showing off its tremendous fish-ness
photo: LoveToKnow
Think of the fish you know best.  They may look like this orange guy:

Having a certain hydro-dynamic shape facilitates movement in the ocean, so faster-moving fish (and marine mammals - think dolphins) tend to taper on both ends.

In the ocean's depths, however, speed is less critical for survival, and bizarre and ancient forms become the norm. Survival in the cold deep water, where there's little oxygen, light, or nutrients, requires exceptional adaptation and so brings out some of our world's crazier-shaped life forms.

Dog Fail

While some animals, such as elephants and wild cats, suffer at the hands of people and have disappeared from much of their ancestral home (or just gone completely extinct...), others have succeeded beyond their wild ancestors' imaginations in the human landscape. Dogs have thrived as well as any species, as this post and this post highlight.

Sometimes dogs do fail at "being dogs", which this post and the hilarious video below (posted by my cousin on Facebook - !!) show really well. I was nearly in tears, so please enjoy.

Actually, the ptarmigan is a lovely bird that lives in the higher northern latitudes and changes its plumage to survive both summer and winter. Males and females look different in summer time, so you all are right.

Ptarmigans don't just change color. Oh no! They also prepare and execute several strategies each year that allow them to thrive in a range of chilly places.

Why so much planning?

Baboon by the bay

While some species suffer from human activity and will avoid people whenever possible, others are able to thrive in human environments.

Animals with certain requirements, such as large areas or specific food or nesting resources, or with body parts we humans like to turn into jewelry, clothing, or sushi, fall into the first category. Those that are smaller, able to eat various types of food or live in multiple environments, and don't threaten people or our stuff, have a better chance of thriving in our increasingly manmade world.

Here's one of the flexible ones – I'm guessing a Chacma baboon in South Africa – having a moment.

Expanding into hostile environments by using less oxygen

we're just coming over to say hi!
photo: Monterrey Bay Aquatic Research Inst.
Last week's post on the Humboldt, or jumbo, squid, taught me (and perhaps you too?) how these red devils of the deep change color and flash each other to communicate. Plus they beat up the people that try to film them doing it.

There's more to this crabby monster than just producing pretty color and light.

Humboldt squid have another mysterious ability that may be enabling them to succeed in more and more places: they thrive in low oxygen environments that most other big critters tend to avoid.

Some background: these beasts already contribute to the ocean environments, both as a predator on crustaceans and as prey for even bigger critters – sperm whales, bill-fishes, tunas, sharks – and people.

Humboldt Squid, the red devils of the deep,communicate through color

I'm in my red phase, please admire from afar.
photo: L. Roberson
What's black and white and red all over?

It's the red devil of the Pacific, a.k.a. the Humboldt, or jumbo, squid.

Humboldt squids spend most of their lives tens of meters under the ocean surface, and they speak to each other in flashes of color, changing their whole bodies quickly from red to white and back again.

Watch jumbo squid speak by 'flashing' each other
(sorry, unable to get this embedded!)

But what does all this flashing mean?

Fitness funnies

Happy Friday!

Back then, it was injury and infection that got us.
Accidents, malnutrition, and acute diseases, such as influenza (flu) or smallpox, outcompeted tofu and pilates.


Good choice, fellas:  recent research found that penguins can taste salty and sour, but not sweet, bitter, or meaty flavors. They've actually lost the genes for these tastes: each of these is temperature-sensitive, and the receptors don't work in freezing cold, so penguins' evolution in the frigid Antarctic environment may have made these genes redundant.


Sometimes, you just need a cookie.

Did you know? 11 myths about colds and flu

not a big fan of the cold....or the flu!
It's cold here on the East Coast of the U.S., and I for one, am not a huge fan. No huge fan needed these days...

Winter cold means people, like me, all across the northern climates are huddling together indoors, taking the bus, car, or train to work instead of walking or cycling, and generally being near others, all of which increases the chances of coming into contact with germs, particularly for cold and flu.

We are mid-way through the flu season here, and the virus is still spreading.

If you've ever had the flu, you know how awful it feels, and it's likely that some of the advice you received from friends and family about dealing with the flu was wrong.

With all the misinformation and bad advice when it comes to dealing with the flu, here are 11 common myths you should consider:

Beetle juice

Not only the fish in the previous post, but other vertebrates, plants, and invertebrates, have antifreeze proteins that stop the growth of ice crystals inside the animal.

While fish in the Arctic and Antarctic seas need to protect themselves against temperatures of -1.9 degrees Celsius (28.5 degrees F), creatures that live on land may face colder temperatures.

A 2012 study showed that the larva of the fire-coloured beetle is an even more efficient anti-freezer. These little grubs can withstand temperatures down to -30 degrees Celsius (-22 degrees F) because their antifreeze proteins are more active than those in cold-water fish.

This study found that the antifreeze proteins in the beetle larvae also interact with adjacent water molecules, which improves the interaction with the ice crystals and, thus, the protection against the severe cold. Do not ask me how these interactions work.

Many of these cold-tolerant insects produce high concentrations of glycerol and other kinds of alcohol molecules that slow ice formation, so although the insect freezes, its cells are not damaged.  Other chemicals (called cryoprotectants) also protect cells when freezing and when thawing.

another freezing water specialist
photo: Paul Cziko
In fact, scientists have identified a number of different types of animal antifreezes, produced by a curious and haphazard variety of species, prompting some to suggest that this adaptation occurred relatively recently, in response to sea level glaciation.

According to molecular biologist Sean Carroll, "The necessity of avoiding freezing has truly been the mother of a great number of evolutionary inventions."

Not only that, but these antifreez proteins  developed separately in Antarctic species and Arctic species (10–30 million years ago and 1–2 million years ago, respectively).  Remember, species in these two communities are isolated and don't interbreed – it's a good example of convergent evolution.

Why (some) fish don't freeze

Early in a bike ride this cold January afternoon, I hit some hidden loose gravel under a big icy puddle on a bike trail and fell, soaking my feet, legs, and hands. Nice job, I know.

No cold feet here - curious Weddell seals under the ice.
Photo: changehali, Wikimedia Commons
I decided to keep going, partly to accompany my companion and partly it seemed silly to just turn back, especially when the next few km were mainly up hill, so I stayed warm for most of the ride (except those cold feet!).

We humans can't survive more than about an hour submerged in icy water (and normally much less, due to exhaustion or blacking out). But what about all those crazy animals that live in the world's various frigid oceans?

You've got your polar bears and sea otters, with their thick, heat-trapping fur, and your pinnipeds (seals, sea lions, walruses) and cetaceans (whales and dolphins), protected by layers of fat, and of course penguins, who use both strategies.

And then there are the antifreeze artists, the animals and plants that survive freezing environments without the benefit of fur or feathers, using just the chemical composition of their body fluids.

Lose weight and save money by slowing down your food buying

Have you made any New Year's resolutions for 2015?

Do they relate to fitness?  Weight loss?  Eating better?  You are not alone.  Over 60% of people in the US do this, at least infrequently, me included (though I'm even behind on that this year!).




Losing weight is the most common New Year's resolution, followed by getting organized and spending less.
