Another thing is test that your doctors can give you, that look at urine, blood, and saliva for toxic substances. These are not for everybody, just a certain population. But, the accuracy of these tests have not yet been proven scientifically. Not everyone needs to go on a detoxification diet, but it certainly can help y...

Rick Steinau with Ask the Exterminator demonstrates how to prevent yellow jackets from nesting in your home's walls. In mid to late summer yellow jacket populations increase. Yellow jackets can find spaces in the veneer or in cracks in bricks or siding. You can hear scratching noises in your walls as the wasps move. Observe wasp activity late in the day when they return to their nest for the night. Treat reachable holes with pesticide dust and a bellows. Leave the hole open to let the wasps f...

August is a time when it is common to see bats flying overhead while taking an evening stroll or night fishing at your favorite spot. The two most common bats in Ohio are the little brown and the big brown bats and both are found in rural and urban settings. Bats serve a valuable purpose for humans because they feed on insects, including mosquitoes and those which plague farmers’ crops. However, bats sometimes create roosts, or gathering places, in people’s homes. Join Wild Ohio’s Donna Danie...
Experts from the World Health Organization just expressed concern for the rising number of measles outbreaks across Europe. Despite a perfectly capable existing vaccine, "immunization coverage has dropped below the necessary threshold of 95%," causing the measles to spread throughout the European region.
Although their effectiveness is waning, antibiotics remain a front-line defense against many infections. However, new science reveals using the wrong antibiotic for an infection could makes things much worse.
Watch this two-part instructional video to begin carving gaming terrain and various art projects out of high density foam. This type of pink foam is called Styrospan. It's easy to carve, inexpensive and can be easily repaired with glue.
Everyone floats in the Dead Sea because the amount of salt in water effects the density. Do a hands-on experiment and practice checking density. Here’s a good science experiment to do in class or at home, if you have access to an electronic balance.
You may remember this badass wall of flames photo... That's because last month I highlighted a tutorial by photographer Barry Elder that showed how to light paint with fire.
Tremendous strides have been made in the treatment and outlook for patients infected with HIV, the human immunodeficiency virus. Treatment with a combination of antiretroviral drugs can keep patients with HIV alive for decades, without symptoms of the infection. The trouble is, if HIV-infected people stop taking their medications, the virus takes over in full force again—because the virus hides out quietly in cells of the immune system, kept in check, but not killed by the treatment.
Various electrochemical reactions requires that anodes do not degrade when used. Carbon is cheap, but degrades easily and platinum is extremely expensive. In a previous video, you learned "How to make cobalt and manganese nitrates", and you saw that titanium could be used as a cathode, but not as an anode due to an effect called passivation.
There's a few reasons why you might want to purify chemicals by recrystallization, but the best one could be luminescence glow-in-the-dark dust.
Bed bugs are parasites not yet known to spread disease — but they cause plenty of irritation. As scientists and landlords search for new ways to deal with the pests, a new study examines how we can deter bed bugs without so many chemicals.
Even the best-maintained kitchens occasionally get a fruit fly infestation. These critters descend, lay eggs (up to 500 at a time!), and then disappear usually only after extreme cleaning efforts (i.e., finally attacking that weird puddle of goo behind your refrigerator).
If you've ever listened to your loved ones sing in the shower or watched a few minutes of American Idol, you would think that the majority of the population is tone deaf. In reality, only about 4 percent of the world's population suffers from tone deafness, or the inability to distinguish between different pitches. Che Guerava, Charles Darwin, and Ulysses S. Grant were all tone deaf.
With a predicated increase in the number of Lyme disease cases in the coming spring season, new research endorses the use of bait boxes to control ticks on the rodents that serve as their hosts.
Watch this science video tutorial from Nurd Rage on how to make a lithium thionyl chloride battery, which is capable of generating 2.8v with enough current to power a LED.
Many modern Android devices use a display technology called AMOLED. These screens differ from traditional LCD displays in that each pixel emits its own light, so a backlight is not required. Even better, when rendering a black element on the screen, AMOLED displays simply don't light up the associated pixels, meaning virtually no power is used. Since black pixels use little to no power on an AMOLED screen, more black pixels means lower battery consumption.
Deke McClelland explains what the Levels and Histogram commands can do in Photoshop in this video tutorial. Levels allows you to adjust the luminance levels allowing you to adjust the contrast and colors within each color channel of an image. Thus, Levels allows you to adjust the individual colors that can be found within a gradient. This command is very similar to the curves command but to a less powerful extent. It is also more efficient than the curves command. The Histogram is another col...
The Nexus 6 is one of the few devices on the market that sports a 1440p "QHD" display. This means that the amount of pixels displayed is higher than almost any other smartphone, which sounds great on the surface, but is not without its drawbacks.
Identify pinion needle scaleWe are going to look at this insect because eggs are being laid. Two year old needles are being cast off. This is a sign of infestation. There is also sparse, open foliage. This tends to be a chronic infestation. The insect is the pinion needle scale. You can see tiny, bean shaped bumps on the 2 year old needles. The insects move to last years new growth and feast on the sap of the needle all summer. You can see egg masses and web on the trunk of the tree. The inse...
Settling a new planet will decrease your pride ratio, because your population will increase when you're settling a new planet. If you're not sure how to even settle planets...
While not cuddly to most, bats are shy, skilled flyers that fill an important role in their environments. A new study reveals a deadly disease decimating North American bat populations has stepped up its attack on vulnerable bat populations in the summer months.
For a company more associated with debugging computer programs, Google's parent company, Alphabet, is making a name for itself by taking on the real thing — mosquitoes.
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.
Antibiotics used to prevent diseases in livestock are creating a world of hurt for humans and the soil we depend on for food. Bacterial resistance to antibiotics is a global health issue. The overuse, underuse, and poor use of these life-saving drugs is rapidly removing them as a treatment option for serious infections in humans—plus bacteria are naturally adaptive.
For regions that experienced a boom in mouse populations last year, scientists say 2017 could see a surge in cases of Lyme disease.
Even as health authorities describe the symptoms of Zika infection in the general population as mild, a new surveillance study finds serious side effects are more common, and serious, than previously thought.
Ecosystem changes caused by agricultural choices in Brazil are creating a dangerous microbe mix in exploding populations of vampire bats and feral pigs.
Bees are the key to pollination and healthy vegetation, and wasps may help by assisting in pest control, but despite their benefits in the world, they're still a real pain in the ass if they're in your face.
In this how-to video, you will learn how to indicate if tree damage has occurred due to a natural gas leak. In this example, a Mexican Elder tree has been damaged by the gas leak. You can tell by the brown leaves. The plastic around the soil has trapped the gas in the soil, cutting off the oxygen from the tree. The Indian Hawthorne in this example has also been damaged. There is some foliage burn on the leaves. The bush will have to be trimmed back in order to save it. There are several plant...
