The human core body temperature can produce about 100 microwatts of thermal energy!

Science research proves that the human body as a warm object (at 98.6 degrees fahrenheit) is also a capable source of energy that can be harnessed to power a cell phone, a pacemaker or any other battery operated device.

This idea is loosely based on the static electricity theory whereby one can prolong an alkaline battery by rubbing it in their hands, but in this technology the kinetic energy and the actual rubbing of the hands is the source scientists are tapping into and as a result new technologies are aiming to replace batteries by harnessing the use of an individual's own body heat as a source to power biomedical devices like pacemakers and heart-rate monitors.

The normal core body temperature of a normal healthy adult at rest is stated to be at 98.6 degrees fahrenheit (or 37.0 degrees celsius, or 310 kelvin).

Our body temperature is fairly consistent but varies slightly due to metabolism whereby the temperature is lower in the early morning due to sleep and rest and higher at night from food intake and the use of the muscles from routine daily physical activity.

This body-generated thermal energy can produce about 100 microwatts, but researchers are developing an apparatus and microchip that may be able to amplify the charge, store or serve as thermal control in order to drive a microelectronic device.

The new chip design incorporates circuits that work at a voltage level much lower than usual as well as extending the operationg duration of portable devices on a single battery charge, it is hoped that the energy-efficient microchip may be efficient enough to run implantable medical devices using ambient energy from the human body heat as its power source.

Today with the widespread use of mobile devices, the development of new cellular technologies seem to have triggered more research in the field of muscle tissue heat generation during exercise so that non-evasive low voltage personal electronic devices for music and cell phones can be used with a smarter, more efficient and eco-friendly source of power: our own bodies.

"You can make dozens of garden and patio lamps at no cost!"

Deter bugs and save on decor items for your next outdoor party by beautifying your yard, garden and patio with joyful charming color and light.

Supplies for this project are free at stores and simple or easy to find,
some reusable items can be obtained from your own recycling bin.


WHAT YOU NEED:

* paint can wooden stir-sticks
* corks from wine bottles
* empty clear plastic pop bottles
* empty yellow plastic yogurt cups
* glue, tape or spray adhesive
* outdoor Christmas lights
- or you can buy up to 50 led lights for under $20 at madscience.com


HERE IS HOW:

STEP 1
Decorate the the empty yellow yogurt cup with pin holes and adhere like a hat on each empty clear plastic pop bottle.
note: I recommend the color yellow so that the lantern will act as a bug light to deter garden insects but you can use multiple colors for festive events or parties, I also prefer a round spherical pop bottle so that the appearance is aesthetically realistic to the store purchased designs.


STEP 2
Use the tip of a pencil to make a hole an inch below the tip of the paint can stir sticks then drill a hole or punch a hole so you can string the lights and mount the clear plastic bottle that will act as a light bulb.
note: if the hole is too big, the lights will slip out so it is better to make the hole small and enlarge as needed.

STEP 3
Secure the distance of the bottle from the stick by slicing the cork in the desired length and use it as a washer.


STEP 4
Make sure the light are working before assembly, string though the hole on the stick before adhering the plastic bottle with its yogurt cup hat.


STEP 5
As you string your assembled lights across the garden, place each one in the ground with the plug end of the string of lights towards the direction of the outlet and allow the wire to nestle on the landscape between plants for camouflage.
note: you can mimic this assembly design and alter it accordingly for overhead hanging patio lanterns by just omitting the ground sticks.

Pringles Planetarium

The Canadian Humble space telescope is the world's smallest space telescope measuring at about the diameter of a pie plate and is packed in the MOST microsatellite which has the size and mass of a carry-on suitcase.

As a fun Science project, you can make your own world's smallest space telescope!

You can create a planetarium projector and space telescope with interchangeable star chart slides for your room.

What you need:

transparent paper for tracing
black construction paper
Maxwell house coffee can cylinder
Pringles chips cylinder can
a collection of Pringles lids
star constellation for Pringels lids: space wall star chart graphics
star chart template for Maxwell house lid: large lid star graphics
a pin
a nail and hammer
scissors
led flashlight
laser pointer


Step 1. How to make your own Pringles space chart telescope:

Click here: space wall star chart graphics to access the star constellation template and trace all the points on the transparent sheet of paper. Using a pin poke thru the transparent sheet of paper transferring the constellation design with holes on the black construction sheet of paper. Using the transparent Pringles lids that you have collected, cut out exact circular templates from the completed construction paper, cut slowly and precisely and insert to each Pringles lid, carefully trim the paper borders for a perfect inset fit to the lid. Using your nail and hammer, punch a hole big enough to look through on the adjacent metallic end side of the Pringles cylinder (be sure there are no sharp ends, to ensure this punch it from the outside inwards).

You can now look thru the interchangeable lids with star constellations to recognize and identify them in the real night sky to get more out of your star gazing or on your own planetarium projector - see Step 2 below.


Step 2. How to make your own Maxwell House cylinder can planetarium:

Click here: large lid star graphics to access the Maxwell House star constellation template for your lid and trace all the points on the transparent sheet of paper. Using a pin poke thru the transparent sheet of paper transferring the constellation design with holes on the black construction sheet of paper. Cut out an exact circular template from the completed construction paper with star constellation holes, cut slowly and precisely and insert to the large blue Maxwell House lid, carefully trim the paper borders for a perfect inset fit to the large plastic lid. This time, use the pin to poke the holes right through the large blue plastic Maxwell House lid transferring the same holes from the paper to the large plastic lid. Insert the led flashlight inside the empty can facing up by having a flashlight that can be made to stand upright (glue in place if necessary).


In a darkened room, turn on the flashlight, place it in the Maxwell House can, put the planetarium cylinder on the floor and place the plastic lid with holes on in order to project your constellations onto the ceiling.

By using your laser pointer, you can quiz your friends or family to see if they can identify the different constellations.

Use the Pringles telescope lid slides to match and find where the constellation are located on the projected ceiling star map to get more out of your planetarium game.

The Maxwell House planetarium projection cylinder can be stripped-off of its label and showcased as a hi-tech looking silver cylinder.

The Pringles' space telescope can be decorated with a space drawing or with a paper size print of Van Gogh's famous 'Starry Night' artwork, simply wrap it around the perimeter of the long cylinder and tape it.

Your space telescope with interchangeable star slide constellations and planetarium are now complete.

Cryopreservation - the freezing fountain of youth is under fire

The word cryobiology is derived from the Greek words 'cryo' meaning 'cold', 'bios' meaning 'life' and 'logos' meaning 'study of' or 'science'.

Today cryobiology is a tangible branch of biology that studies the effects of living things in extreme below freezing temperatures.


Behind the frozen veneer of cryobiology life extension innovation

There are many distinctions in the cryo-science practice and the freezing of non-living matter, but in cryobiology the main focus is in the study of preserving life in biological matter including proteins, cells, tissues, organs and organisms in their entirety.

The freezing temperatures in cryo-science may range from very cold, sub zero, hypothermic conditions to extreme temperatures of –300 °C.

As a result of the below freezing temperature measurement studies, scientists created a new temperature scale from the commonly known Fahrenheit and Celsius, which they call the Kelvin and Rankine scales: whereas –300 °C or –508 °F translates to -27 K (conversion calculator)

The field of research in cryobiology techniques, evolved procedures and emerging technologies is primarily focused on trying to achieve cryopreservation suspension and reanimation. In recent years, with support of emergency medicine, the basis that cryobiology may surpass organ transplantation and may have the ability to increase the length of a life may be slowly becoming a reality. However, behind the frozen veneer of life extension innovation lies the very cause of the opposition. The progressing cryobiology research of cheating death and extending the human lifeline is also the same reason for fueling a heated ethical debate with a strong opposition on the morality of cryo-science.

Many medical procedures today would not even be possible if it had not been for cryobiology. The newly evolved medical procedures in the cryobiology field have been successful in treating certain skin tissues from lesions, sustaining cell life and also improved quality of life with various new cryosurgery transplantation processes. Thus in essence, cryobiology is in fact already extending life. The ability to lengthen a person's life allowed many groups to surface as societies pursuing, funding and supporting cryonic suspension of humans. However, the belief that the length of life should not be tampered triggered other opposing parties hindering the research and the science of cryobiology altogether.

In addition to the ethics of meddling with mother nature and as cryobiology is being further explored, the complications of these processes are also becoming well known. Another supporting argument from the opposition to the science that is starting to surface is that any type of cryobiological procedure affects the cells and the surrounding areas causing, in many cases, extensive irreversible damage. In cryosurgery, the reported damage is almost equal to the success of the treatment for the problem. This damage on the cellular level can cause future problems that will require treatment producing a cryo-dependency cycle for the patient.

Damage may also occur in cryopreservation suspension where defects have been known to be caused by implications; the exact underlined cause is still unknown to the science. The cost of most cryobiological procedures is still very expensive and unless a payment plan similar to life insurance can be implemented, the price tag for prolonging one's life with cryobiology is too expensive for the average person to afford. The fact that there are not any successful resuscitations recorded for cryonics patients demonstrates the probability that the damage factor occurrence may be preventing reanimation of a frozen human being and to date it is still not possible.

While there is much controversy about whether cryobiology advancement is scientifically or ethically justifiable, it does offer the possibility of redefining mortality. As a result, several societies for cryobiology based on the life preservation theory have surfaced around the world through the years with members that date back to as early as 1964.

With the many important medical contributions of cryobiology being promoted in the field of organ transplantation and the high expectation of cryopreservation as a future technology, medical research may be the governing force in the cryobiology science that can sway the argument in favor of pursuing the research further despite the current set-backs
