Both professional and home cooks have been rinsing raw chicken and turkey before cooking it for what seems like forever. It's one of those divisive practices—either you do it or you don't, and people tend to be rather opinionated on their stances.
For as long as 14,000 years, the First Nations people of the Heitsuk Nation have made their home along the Central Coast of the Canadian province of British Columbia. Among the territory's inlets, islands, rivers, and valleys lie a clay deposit on the north side of Kisameet Bay, near King Island. For as long as most can remember, the tribe has used the clay as medicine. Now science says microbes that live in that clay may have important antibacterial properties.
We might think of Zika as a mosquito-borne virus that effects developing fetuses, but, it also can be passed through sex by either a man or a woman, just like herpes and other STD viruses. New research has shown that vaginal bacteria can inhibit sexually transmitted Zika virus and Herpes Simplex Virus-2 in women.
Have you ever had a burning sensation when you urinate? Low fever, back pain, and maybe cloudy urine? Male or female, it could have been a urinary tract infection. If it lasted long enough, the chances are good you went to the doctor for help. For about 20% of women, standard testing for a UTI does not reveal the presence of infection-causing bacteria, even though bacteria may be causing their symptoms. Well, a new test may provide better answers.
On October 17, 1943, a story in the New York Herald Tribune read "Many laymen — husbands, wives, parents, brothers, sisters, friends — beg Dr. Keefer for penicillin," according to the American Chemical Society. Dr. Chester Keefer of Boston was responsible for rationing the new miracle drug, penicillin.
How can bacteria that lives in the throat of 10%–35% of people—without causing an infection—cause life-threatening meningitis and sepsis in others?
Antibiotic-resistant infections that usually occur only in hospital settings are spreading in communities, increasing hospital stays—and danger—for young children.
We all know you are what you eat—or so the expression goes—but it's good to remember that what you are (at least intestinally) is mainly bacteria. A new study has shown that what you eat, and how your gut microbiome reacts to that food, might be a key player in your risk of developing a certain type of colon cancer—and changing your diet can help decrease your risk.
There are certain foods and beverages that can actually brighten your smile or improve your dental health when you chew or sip them. Once you understand their chemical properties or textures, you can look to items you already have in your cupboards or refrigerator to help keep your teeth looking and feeling their best.
One formula that you will run into in Calculus is calculating the percentage growth rate using a logarithmic derivative, elasticity of demand, relation among elasticity of demand and also revenue. In this video you will learn the different formulas that are used, methods of solving each formula, and also the full solutions.
This video shows the method to use differential equations to represent growth. Consider the function y=multiple of C & e raised to kx or Ce^(kx). Differentiating it with respect to x, we get dy/dx=kCe^(kx) or ky. So, the solution of the differential equation dy/dx=ky is Ce^(kx). There are two possibilities in the function y=e^(kx). It can be exponentially growth or decay function. This depends on the value of k. If k is greater than 0 or k>0, we get an exponential growth function. On the othe...
The growing list of dangerous antibiotic resistant organisms has just acquired three new members. Researchers have discovered three new species of Klebsiella bacteria, all of which can cause life-threatening infections and have genes that make them resistant to commonly used antibiotics.
The evidence is mounting and is becoming indisputable: Gut bacteria play a role in strokes and heart attacks. The link may seem a little far-fetched, but cardiovascular disease may have less to do with what we eat and more to do with what chemicals gut bacteria make from the food we eat.
We know that healthcare-related facilities can be fertile ground for antibiotic-resistant bacteria, but recent research suggests your produce aisle might be too.
The future of forests looks dreary in the face of a warming climate, but scientists are exploring the relationship between soil microbes and the ability of trees to move to higher altitudes, a key component of their survival.
Exposed to hormones, pharmaceuticals, and other chemicals, the beautiful wild fish in Canada's Grand River have taken on some pretty odd characteristics—they're turning into females. A long-term study suggests using bacteria to manage polluted water could turn the tide for feminized fish.
Bacteriotherapy sounds a lot more amenable of a term than "fecal transplant," yet they're both treatments that use bacteria itself to cure or treat infections. Fecal transplants, specifically, are an up-and-coming treatment option for a potentially deadly and difficult-to-treat diarrheal infection called Clostridium difficile.
Want to calculate percentage growth rates (also known as the relative rates of change)? Learn how with this free video calculus lesson, which covers calculating the percentage growth rate using a logarithmic derivative, elasticity of demand and the relation between elasticity of demand and revenue. From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts. And, thanks to the Internet, it's easier than ever t...
Winter moths (operophtera brumata) can be a nuisance to your trees during early spring time. The biggest concern is the larva, which is a caterpillar/inch-worm feed on the budding leaves of deciduous trees and you won't really notice it until your leaves are at their full size. A good way to get rid of the moths is with a bacterium called, BT (bacillus thuringiensis)or Spinosad a derivative of a bacterium. If you have really big trees, you may need to get an arborist to treat your trees.
Learn how to remove pet stains and odors quickly and easily so you no longer have to worry about occasional accidents. These are the items you are going to need: some clean old towels, paper towels,
Gonorrhea infections reached a peak in 1975, then decreased until 2009, when infection rate started rising and has increased each year since. With the rise of antibiotic resistance, those numbers are only going to get worse — unless we find new treatments against the bacteria.
Everything from disposed of drugs to hormones and disease-causing bacteria — anything that is rinsed or flushed down the drain — can contaminate wastewater.
The rate of preterm birth has been increasing in the United States for unknown reasons, causing increased health risks for infants born too soon. But researchers may have found a signal that could help doctors plan ahead for, or even prevent, early birth with a simple swab of the vagina and cervix during pregnancy.
As fun as it is to see Fido's face light up when you feed him table scraps, American dogs are getting fat. The good news is that research is homing in on nutritional strategies to boost canine capabilities to maintain a healthy weight.
Joe McKenna died when he was 30 years old. A young married man with his future ahead of him, he was cleaning up the station where he worked as a fireman. Struck by a piece of equipment fallen from a shelf, Joe complained of a sore shoulder. Over the next week, Joe worsened and ended up in the hospital. Chilled, feverish, and delirious, his organs shut down from an infection we'd now call septic shock.
The story of Helicobacter pylori is a real testament to the tenacity of medical researchers to prove their hypothesis. It took decades before the scientific world would accept that the bacteria H. pylori caused ulcers.
As you might guess, one of the domains in which Microsoft Excel really excels is finance math. Brush up on the stuff for your next or current job with this how-to. In this tutorial from everyone's favorite digital spreadsheet guru, YouTube's ExcelIsFun, the 11th installment in his "Excel Finance Class" series of free video lessons, you'll learn how to calculate the Earnings per Share EPS, Price to Earnings (PE), Dividends per Share, Internal Growth and Sustainable Growth ratios in Excel.
The concept of percentage growth or decline is confusing to a lot of people. If you're one of those people, watch this video. It breaks down how percentage change and growth rates work and how you can calculate them from any pair of numbers.
With more and more movies being released in 3-D, it's important to remember a little thing called bacteria. If you want to be free of another person's germs, then you need to think about those 3-D glasses. They're prime targets for bacteria and need to be cleaned properly.
How to design flower arrangements and what tools are needed:
Whether or not a microbe is successful at establishing an infection depends both on the microbe and the host. Scientists from Duke found that a single DNA change can allow Salmonella typhi, the bacteria that causes typhoid fever, to invade cells. That single genetic variation increased the amount of cholesterol on cell membranes that Salmonella and other bacteria use as a docking station to attach to a cell to invade it. They also found that common cholesterol-lowering drugs protected zebrafi...
Drug-resistant bacteria have made curing some infections challenging, if not nearly impossible. By 2050, it's estimated that 10 million people will be dying annually from infections with antibiotic-resistant organisms.
A tiny louse is responsible for decimating the citrus industry. Diaphorina citri, the louse in question, better known as the Asian citrus psyllid, harbors and spreads the "Candidatus Liberibacter asiaticus" bacteria that causes citrus greening disease.
All fields of study have their own language. For people interested in learning about microbes, the language can sometimes be downright difficult — but it doesn't need to be. From antibiotics to xerophiles, we have you covered in an easy-to-understand glossary.
What do Leo Tolstoy (writer), Beethoven (composer), Paul Gaugin (artist), and Adolf Hitler (politician) have in common? They are all considered to have suffered from the sexually transmitted disease syphilis.
There's no shortage of ways to filter water, but it doesn't get much simpler than this. Researchers at MIT have found that you can turn dirty water into drinking water with nothing more than a stick.
In this tutorial, we learn how to detect and avoid bad breath. If your mouth is very dry, it's going to smell worse and worse. The more oxygen and moisture that you have in your mouth, the less bacteria will be inside it. For people with halitosis, they have a big problem with bad breath. Bacteria lives in your tongue, so you can't scrape them away. You can take a test to see how bad your breath is with a machine. After you do this test, you can learn how to keep more hydrated. Once you have ...
-It is very important that you choose the right counter top. Although granite and marble may look good, they are not kind to the environment because they are mine deep out of the Earth.
Air conditioning systems are cold and wet and make great breeding grounds for bacteria and mold, and adding a nasty odor to the air coming out of the vents.
Each year an apple tree should produce three things: new growth, fruit buds on last year's and older growth, and fruit on those fruit buds formed in previous years. In order to keep an apple tree in balance and fruiting, one must prune. However, pruning is often done poorly. In this, the first installment of his series on practical apple tree pruning, Stephen Hayes of Fruitwise Heritage Apples looks at the general structure of the apple tree.
