Honey is a Health & Fitness Queen

With a lot of great health and fitness benefits, honey should be a common staple in people’s daily diets. Other than its great taste, it has numerous benefits for our bodies, immune systems, weight, and energy which you may not be aware of.

Honey is a source of a variety of vitamins, minerals and amino acids. The main vitamins it provides are niacin, riboflavin and pantothetic acid, and the main minerals are calcium, copper, iron, magnesium, manganese, phosphorus, potassium and zinc. Importantly, the amount of these substances in honey varies depending on its floral source, just as its color and taste vary.

On top of this, what are the main health benefits of honey?

Komodo Dragons: 11 Things You Didn’t Know — Photo Gallery!

Komodo dragon close up for Komodo dragon facts and photo gallery

Perhaps fewer than 5,000 Komodo dragons remain in the wild - victims of poaching, human encroachment, and loss of prey due to human hunting.

Wild Komodo dragons (Varanus komodoensis) inhabit Komodo National Park in the center of Indonesia’s archipelago. The park is comprised of the islands of Komodo, Pada, and Rinca. The limited range of the Komodo dragon makes this species vulnerable to extinction.

To help raise awareness for these large and lovely lizards, here are 11 things you didn’t know about Komodo dragons — and a compilation of adorable photos! Enjoy!

Marine “Dead Zones” Will Increase, Scientists Predict

Underwater video frame of the sea floor in the Western Baltic covered with dead or dying creaturs due oxygen depletionSo-called “dead zones”–patches of ocean lacking aerobic (oxygen breathing) life–will most likely increase due to a rise in carbon dioxide (CO2) concentrations.

Because of CO2 build up in the atmosphere, its level of concentration in the oceans also increases. There, some of the CO2 converts to a simple acid called carbonic acid. (H2CO3).

What is becoming a much-studied phenomenon in recent years, these dead zones of depleted oxygen (02) - typically found at depths between 300 and 600 meters–are the result of several factors working separately and in combination: lower sea surface 02 levels, less heat exchanging (”ventilation”) with mid-level ocean depths due to over-all warming, and “euthrophication events” (an over-growth of a species due to excess nutrients).

New Process Touted as Breakthrough for Cellulosic Ethanol

Mascoma Corp. says it has a way to make switchgrass such as this could be a more common and affordable source of ethanol.

Mascoma Corp. says it has found a way to remove several steps from the process of making cellulosic ethanol, cutting the cost and time it takes to make the fuel, while increasing yields.

The Lebanon, N.H.-based company says it has made advances in consolidated bioprocessing, a process that uses engineered microorganism to make ethanol from cellulosic biomass, such as grasses, stalks and wood waste. Mascoma’s CBP process eliminates the need to produce costly cellulase enzymes, by producing the cellulase and ethanol in a single step.

30% Ocean Mercury Rise Linked to Asian Coal Plants

Sampling Mercury in the Eastern Pacific OceanWorld wide, 75 percent of human exposure to mercury is  from the consumption of marine fish and shell fish. In the U.S., about 40 percent of all human exposure to mercury is from tuna harvested in the Pacific Ocean, according to Elsie Sunderland, a coauthor of the recent US Geologic Survey study.

Data used in this study comes from one of 15 (so far) research cruises that are part of a much larger, international project called CLIVAR; the Climate Variability (CLIVAR) Repeat Hydrography/CO2 research   program.

Data analysis of the water samples indicated that total mercury levels in the North Pacific Ocean water have risen about 30 percent over the last 20 years.

Ancient Microbes Discovered Thriving Under Antarctic Glacier

Antarctic Microbes - Environmental Conditions

Researchers in have discovered ancient, extremophile life forms that survive with neither light nor oxygen underground in Antarctica.

From the surface, the McMurdo Dry Valleys of Eastern Antarctica appears to be one of the most desolate places on Earth. And indeed it is. Apart from a few glaciers, the land is ice-free. No animals live here, and what few plants are able to are simple planktonic forms. But recently, a team of researchers have discovered evidence of a thriving community of extremophile microbes thriving several hundred feet below the barren surface.

Bacteria Turns Excess Clean Energy Into Methane for Storage

Scientists at Pennsylvania State University have discovered a solution to the problem of reliable storage for alternative energy: a bacteria that can convert electricity to methane when combined with CO2.

Any surplus power from wind, solar, or tidal sources is fed into the bacteria and combined with CO2 from the atmosphere to create methane for storage. Methane is a clean-burning gas and 80% of energy fed into the process was retained at the end.

Genetically Engineered Bacteria to Measure Water Quality

Researchers at Tel Aviv University have developed a laboratory the size of a microchip that can be used to measure water quality. Using genetically engineered bacteria that light up when in contact with pre-determined pollutants, this water quality lab will detect and communicate “contact” with monitoring systems. It’s a nano sized version of the robot fish that we recently looked at.

Dairy - The Udder Truth

Gooey melted cheese on pizza, a glass of cold milk with freshly baked cookies, ice cream on a hot summer day… who hasn’t at one time or another enjoyed something made from milk?

Dairy products are part of most American diets on a daily basis, but what is the health and environmental impact of this high demand for milk?

The production of much of the milk in this country is done in large scale-operations, some having thousands of cows.

That’s a lot of manure to be dealt with, this reduces the air quality (especially for people living near the dairy operation), and consistently finds its way into our rivers, streams, and groundwater.

Man-Made Bacteria Produces a Fuel That’s Better Than Gas

Researchers reported Monday that they have re-engineered a common bacteria to produce complex and energy-dense alcohols similar to the hydrocarbon compounds found in fuels such as gasoline. This is the first time these types of alcohols have been synthesized by bacteria (man-made or otherwise) in the lab.

E. coli is normally found in the guts of most warm-blooded animals (yes, even yours) and if you’ve had an encounter with it that you remember, chances are you spent the weekend on the toilet wishing you were dead. Yet, while it’s true that some strains of e. coli can cause food poisoning in humans, most are actually quite harmless.
