Physics Students Calculate How Long a Vampire Needs To Drink Your Blood

A bite to the neck and a clean getaway—that’s what a vampire needs. A group of physics students from the University of Leicester calculated exactly how long a vampire would need to accomplish those two things: about 6.4 minutes. They published their findings in the university’s Journal of Physics Special Topics.

Not taking into account the anti-coagulant. 😉

Depends on the vampire type. In some movies they just chew the throat open, in others their fangs are hypodermic needles and the blood drained goes directly into the vampires bloodstream. Any of these differences would vastly affect the speed of the blood loss.

This Is What Happens to Your Body the Longer You Go Without Sleep

A friend and co-worker in high school was trying to work full time, school full time, and still keep an active social life.  They fell asleep at the wheel, went off the road, crashing (in both senses of the word).  Injuries were severe – when I last saw them, they had intelligence and vocabulary but struggled to say the words.  I haven’t seen them in years, but do remember seeing them on Facebook.  It was really rough, getting the news about the crash while at work.

Please don’t let that happen to you or someone you know.  I’ve had close calls, stupidly thinking I could “push through it”.  Even today, I have time where I learn that I haven’t been sleeping as much or as well as I should be.

Man Finds Out Wife Is Pregnant Via Reddit’s Analysis of Her FitBit Data

The FitBit Activity Tracker—that bracelet thing that makes your parents feel like they’re participating in Modernity—captures all kinds of real-time data related to your health, which can add up to some unsettling insights into your general disposition (for example, it knows when you’ve been dumped).

Wait, so did she know yet? Also, as a newly pregnant, WTF does being stuffed crust pizza do to one’s heartbeat?!

Also, remember that Christian blogger dude who claimed he gotten a positive pregnancy test after taking his wife’s pee out of the toilet? Man, that dude sure sucked at life and lying.

You Can Train Your Body Into Thinking It’s Had Medicine

The results were part of a well-known and seemingly mundane phenomenon that has been driving a quiet revolution in immunology. Its proponents hope that by cutting drug doses, it will not only minimise harmful side-effects but also slash billions from healthcare costs, transforming treatment for conditions such as autoimmune disorders and cancer. The secret? Teaching your body how to respond to a particular medicine, so that in future it can trigger the same change on its own.

This is at least a second cup kind of article, so I’ll be back because I’m curious if the effect is transferable.

Clinically, placebos been at least 50% as effective as real drugs.  But this is more than just a mere placebo effect. It’s a true form of conditioning the body’s response.  It creates a trigger based on sensations and memory whether the patient knows what they are taking is the real medicine or not. Placebos mimic medicine from the beginning and works more effectively if the patient is fooled into thinking it works. No deception is required here.

We All Need Speed

… there are lots of workouts runners can–and should–do regularly. Training variety improves your fitness, staves off injuries, and keeps motivation high (plus it allows me to eat more of my wife’s lasagna). But if pressed to name the one workout that has the greatest impact on racing performance at any distance, I’d answer with a clear conscience: the tempo run.
Tempo runs will make you a stronger miler, a faster 5-K runner, a more powerful 10-K runner, and a less-fatigued marathoner. How can one workout benefit such a wide range of race distances? Simply put: Tempo runs teach your body to run faster before fatiguing.

I’m still weeks away from even being able to run :/

Lawsuit Claims Fitbit Devices Dangerously Underestimate Heart Rate

With some Fitbit devices, every beat may not get counted, according to claims in a proposed nationwide class action lawsuit filed Tuesday.

Three plaintiffs claim that their Fitbit wrist-based heart monitors, “Charge HR” and “Surge,” do not and cannot accurately measure heart rate as advertised. Those sales pitches claim that both products, which are sold for around $150 and $250, respectively, can continuously and accurately monitor heart rate, even during exercise—under tag lines such as “every beat counts.” But the lawsuit claims that the heart rate monitors, which tout “PurePulse Tracker” technology, seem particularly incapable of accurately measuring elevated heart rates, often reading dangerously underestimated rates during workouts.

I’m not surprised – I’ve been reading a lot of the Heart Rate Monitors (HRMs) that use LEDs at the wrist rather than the chest strap.  The DCRainMaker reviews for the Surge and Charge HR also demonstrated inaccuracy to the point of being useless.  Either Fitbit will be accountable (unlikely), or they’ll update packaging…  DCRainMaker has more information and good points about the suit.

That said, the article says the suit claims using LEDs for HRM is useless but that’s not true.  Mio has had the tech and patents for a while – they recently licensed to Garmin for the FR225, which is the most accurate new wearable to date.  Sadly, the FR225 was supplanted after only 4 months on the market with the FR235… which uses the Garmin sensor, that is noticeably less accurate.

Fear Can Actually Curdle Your Blood

The next time someone refers to a horror movie as “bloodcurdling,” they might actually be kinda right. A new study shows that the fear experienced when watching scary movies is in fact associated with an increase in clotting agents in the blood.

The fear response includes a big squirt of epinephrine which increases your heart rate and constricts blood vessels so you can run from the bear faster and bleed less when it bites. That your body also dumps clotting factors dovetails with this system nicely. What’s really surprising is that this hadn’t been recognized previously.

But I’d like to see if the findings stand up in a larger sample size.

This Ingestible Health Sensor Could Help Cut Down On Doctor Visits

From drug-delivering microbots to cancer-fighting nano-swarms, the age of ingestible, autonomous health devices is upon us. So it was only a matter of time before somebody built a miniature stethoscope that sits in your GI tract monitoring your vital signs.

This Stretchy Cloth Could Become Underwear that Monitors Your Heart Rate

Here’s new tech that’ll make wearables as non-invasive as a Band-Aid. Japanese researchers have created a printable conducive ink on cloth, which means your boxer briefs or sports bra could one day track your heart rate (among other things).

The goal there is to swipe, pinch, tap, and drag your fingers across these smart threads to answer calls or turn off lights, just like you would on a mousepad or smartphone.

I don’t think they’ve thought this through… 😉

I, for one, cannot wait to see the hilarity ensue due to accidental touches. Better than autocorrect, I expect.

How We Discovered The Dark Side Of Wearable Fitness Trackers

Wearable technologies like fitness trackers are becoming hugely popular, leading many to speculate about the potential for implantable technologies to augment human biology. The question that is often not asked however is: “How do we feel about living with technology on (or in) our bodies 24/7?”

The article doesn’t mention the fitness data that was collected during an earthquake in California.  It’s interesting to be able to see when and where the earthquake was felt, but rather scary that data is being collected all the time (aside from charging).  Mobile phones don’t give all the same data, but could.  Some might – ANT support covers most of the devices that I know of.

I am glad if it motivates someone to be more active.  I’m just concerned about how that data is going to be used further down the road.
