Every day we pass bridges, whether it's a foot bridge, a highway overpass, a span over water, or a viaduct over a valley. We pass on these structures without even thinking of the engineering genius that went into their design and construction, let alone the science behind their strength.
This video shows a method of cleaning LP records using steam. He uses a Perfection steamer and a record cleaning machine with vacuums, along with a set of brushes, Disc Doctor cleaner, and laboratory grade water. He uses distilled water in the steamer. He turns the turntable on, applies the cleaner, spreads it with a brush, and applies the steam while the record turns. After the steaming is done, he continues rubbing it with the brush, and turns on a vacuum. Next he runs the steamer of the re...
Bats getting caught in houses is a regional problem. In general, bats are scared of humans, but they will bite when they feel cornered. The New York State Health Department produced this video to urge New Yorkers to avoid the risk of rabies and rabies treatment by capturing and submitting for laboratory testing any bat found in their home that may have come in contact with humans or pets.
This is a guided hands-on laboratory activity to help a student understand the proper and safe use of a multimeter to measure voltage using an electronic labs kit. This video guides the student through the proper techniques for measuring voltage with a multimeter.

Using a huge jar and with water colored with die in it you can make clouds. To do this set up the apparatus as shown in the video. Now open up the top valve and blow air into the jar. Now this causes the air inside to be compressed as we are pushing more air into the confined jar. This creates a high pressure inside the ball. To understand how clouds are formed you need to know two concepts. The first concept is that as pressurized gas expands it cools. The second thing is that warm gases can...
This video shows you how to calculate the percentage yield in chemistry. To find the percentage yield, you will need to divide the actual yield by the theoretical yield. Then, multiply it by 100: i.e. % yield = actual yield/theoretical yield x 100. An actual yield is the amount of a substance produced in an actual laboratory experiment. It is based on an actual physical measurement of a quantity. The theoretical yield is the yield as is calculated on paper: i.e. through calculations. Therefor...
Notorious hacker Chris Tarnovsky opens his underground laboratory to WIRED, providing a peek into the world of satellite television smart-card hacking. This complicated process involves nail polish, a pin head and various acids -- so don't try this at home (unless you're Chris Tarnovsky)! Chances are you won't even know what's going on here, but that's not going to stop you from watching this video tutorial on how to reverse-engineer a satellite TV smart card, is it?
This is a guided hands-on laboratory activity to help a student understand the proper and safe use of a multimeter to measure electrical resistance. These two video guides the student through the proper techniques for measuring resistance with a multimeter, but you'll need some assorted resistors, a rectifying diode, a photo cell, an electronic labs kit, and some other stuff.

Lords of Shadows is yet another video game in the popular Castlevania franchise, which has been around since the days of the NES. In this lengthy walkthrough, you'll see all the vampire killing action, set in the Middle Ages, with protagonist Gabriel Belmont. This is a handy video guide if you ever get stumped on a level.
Have you ever wanted to control a swarm of robots? Well, now you can! Robotics researchers at New York University (NYU) have created an app which controls 'bots from your smartphone, using augmented reality. This AR app would certainly come in handy when you want to make a coffee from the comfort of your couch, but let's not get ahead of ourselves!
When sleep problems becomes chronic, it can morph into psychophysiological insomnia: As you prepare for bed, you begin to get nervous about sleeping. In this video, David Schulman, MD, director of the Emory Sleep Disorders Laboratory in Atlanta, explains how the body reacts to the expectation of insomnia. He offers simple changes you can make to help break the cycle.
Resflux is an Xposed mod developed by Julian Paolo Dayag, aka WisdomSky, that provides users with a straightforward and functional way to customize and theme almost every aspect of the packages (apps and system components) installed on their Android device.
The tradition of using cutting edge technology to prepare for missions in space, in this case, augmented reality, continues with a new team of international astronauts slated to board the International Space Station (ISS) later this year.
Rumors are swirling today that NASA's Jet Propulsion Laboratory (JPL) may have shown us the first public glimpse of the next-generation HoloLens. Are they real? Or just a prototype? We've been digging in all day to find the answers.

Do not discount the "pretty" rocks found along with gold. The sapphires you see are worth many times more than gold. Sapphire (& Ruby, (corundum), is like garnet, a relatively high specific gravity that will catch in a sluice readily. These gems act as gold, they will drop behind a boulder, in bedrock cracks, and set up in the stratiform layers of a bar on the inside bend of a stream. In a perfect (laboratory world) a river bar sets up from front to back: Gold, Platinum, Lead, Iron Ore (black...
On July 20, 1969, humans set foot on the moon for the first time. But some say our microbes beat us there. With the Space Age came new questions about microscopic invaders from outer space and concern about where we are leaving our microbial footprints. The questions are even more relevant today.
Wherever there are people, the party is sure to follow. Well, a party of microbes, at least. That is what scientists at NASA's Jet Propulsion Laboratory have found after a 30-day microbial observation of the inflatable lunar/Mars analog habitat (IMAH).
It is not just a bad summer for ticks — it has been a bad decade for the spread of tick-borne infections. New surveillance from the CDC reports rapid expansion and increase in cases of babesiosis, a sometimes life-threatening disease, in Wisconsin.
Listeria monocytogenes bacteria don't play fair. Healthy people can usually handle the food-borne infection, but the bacterial infection hits pregnant women, fetuses and cancer patients very hard. Interestingly, a new study found that other bacteria may help prevent Listeria infections in those people.
