#Dwarf Lemurs Hibernate Like Bears The western fat-tailed dwarf lemur was the only primate thought to be a hibernator.
The new results published in several studies today (June 3) in the journal Proceedings of the National Academy of Sciences (PNAS) were found by analyzing the fraction of different carbon isotopes or atoms of the same chemical with different molecular weights
The 10 Biggest Mysteries of the First Humans Diet insight Because plants using different methods of photosynthesis to grow absorb different amounts of carbon isotopes the ratio of those isotopes in dental enamel can reveal insights
For instance so called C3 plants absorb more of the heavy isotope carbon-13 into tissue than do C4 or CAM plants.
To analyze what the ancient human ancestors were eating the team analyzed the fraction of different carbon isotopes in teeth from every early human fossil that could be sampled:
Now thanks to stable-isotope analyses we no longer have to guess and the broad pattern of early hominin dietary evolution is established.
#Earthworms Trap Carbon, But Do They Influence Climate Change?(ISNS)--Earthworms have long been the organic gardener's friend.
when researchers reported in Nature Climate Change  that earthworms contribute to greenhouse gas emissions.
and a 42 percent increase in the emissions of another greenhouse gas nitrous oxide. Â Jan Willem van Groenigen of Wageningen University in The netherlands and lead author on the Nature Climate Change article doesn't advocate exterminating earthworms. oeyou cannot say earthworms are good or bad.
They re almost indispensible for farming systems but they also have the side effect of increasing the emissions of greenhouse gases.
or burned it releases carbon dioxide. But in a process called stabilization earthworms convert the digestible carbon to a form that stays in the soil.
They re stabilizing it through their fecal material. That type of carbon is more resistant to decay said Deborah Neher of the University of Vermont in Burlington.
 Earthworms ingest the organic matter or litter that lies atop the soil. The litter is ground to a pulp in their gizzard broken down and digested by their gut bacteria
Their excrement also adds physical structure to the soil that holds in the carbon reduces erosion
They measured the carbon dioxide emission carbon mineralization and carbon stabilization of a batch of soil with just microbes and compared that with a batch of soil with microbes and earthworms.
They found that earthworm-stocked soil releases no more carbon dioxide than soil with microbes alone. In fact the earthworms excreted carbon that stuck in the ground rather than releasing it into the air.
Essentially earthworms created a carbon trap. We're losing the litter on the surface of the soil
which has affects on future forest composition but a lot of that may be moving deeper into the soil
and holding the carbon there said Neher. The carbon is just moving into deeper layers in the soil.
Many of the proposed ideas to reduce greenhouse gas emission involve trapping carbon in the soil
but these small creatures have beaten us to it. Other new studies find that the fecal matter of millipedes
and oribatid mites also transform carbon into its more decay resistant form. The second study was conducted over 54 days too short a time to judge the total effect of earthworms on the environment.
and help reduce greenhouse gases in the environment. Whether or not earthworms contribute to climate change both sides agree that earthworms have unmistakable benefits.

And while eggs are high in cholesterol (186 milligrams 184 of them in the yolk) they're relatively low in saturated fat (1. 6 grams in the yolk.
In fact during my 20 years of counseling people with high cholesterol just reducing their saturated fat intake to a range of 4 percent to 7 percent of their calories causes their blood cholesterol levels

Protein. Eggs are considered the gold standard that other proteins are measured against. Because of the superior amino acid mix an egg's six grams of protein are absorbed easily
and efficiently used by the body. The egg is also low-calorie (74 calories. Choline.
Yolks are one of the best sources of this essential nutrient. Choline is needed for brain development in a growing fetus
and zeaxanthin than greens these phytochemicals are more absorbable because of the presence of fat in the yolk.
Vitamin d. Eggs are one of the few natural sources of Vitamin d important for the bones and teeth.
Vitamin d aids the absorption of calcium which is important for the heart and colon as well.

but there are some lesser-known gases that also jeopardize the Earth's climate future. This list includes methane nitrous oxide chlorofluorocarbons (CFCS) hydrofluorocarbons (HFCS) and several others.
These gases may make up a small percentage of the emissions society generates but they pack a devastating punch when released.
The threat level for each of these gases varies based on several factors most notably their lifetime in the atmosphere and their potential to influence global warming.
Reducing the emissions of those gases in addition to those from carbon dioxide is critical to achieving a stable climate.
Taking action against greenhouse-gas emissions For decades climate-change discussions have centered on actions to curb carbon-dioxide emissions.
Now government officials are beginning to focus their attention on reducing other types of harmful gases including HFC emissions.
After reducing carbon-dioxide emissions from power plants the phasing-down of HFCS is the next-biggest step the United states can take toward achieving its goal of reducing greenhouse-gas emissions by 17 percent by 2020 according to the World Resources Institute.
The threat level of a gas is determined in part by its global-warming potential (GWP) a measurement of how much heat a gas can trap in the atmosphere.
It is expressed as a ratio of a gas's heat-trapping ability relative to that of carbon dioxide (which has standardized a GWP at one)
Many greenhouse gases have much higher GWPS than carbon dioxide. CFCS which are used most widely as refrigerants propellants
or the average length of time a molecule of gas exists in the atmosphere before being converted into another chemical compound or absorbing back into a sink like a forest or ocean.
and less so on the potential damages of gases with high global-warming potential In 1989 the Montreal Protocol called for a phaseout of several ozone-depleting substances namely CFCS and hydrochlorofluorocarbons (HCFCS).
All of the United nations member nations now comply with it which has led to the effective phaseout of 97 percent of all ozone-depleting substances the equivalent of more than 200 gigatons of greenhouse gases and nearly six years'worth of total

Women in the study who ate more than one serving daily of low-fat dairy were no more likely to die than those who ate less than half a serving daily.
The researchers said their findings show that it was saturated fat from dairy products in particular rather than saturated fat in the diet in general that was linked with breast cancer survival.
But there's a fairly substantial amount of fat in it she said so it would be worthwhile to compare the effects of consuming it to consuming both lower-and higher-fat products.
To find out when this wet period took place the scientists used radiocarbon dating a technique that measures the ratio of different forms of carbon to find an object's age.
They implored Congress to take action to cut carbon pollution and promote policies that will protect future generations from even greater climate threats predicted by scientists.

whether applying medical grade honey to wound sites in patients undergoing dialysis showed advantages over standard antibiotic use.
The researchers worked with dialysis patients because having a catheter inserted is a regular procedure for the hundreds of thousands of kidney dialysis patients.
They found that using honey showed no advantages over standard antibiotic use and was in fact worse for diabetic dialysis patients.
Getting something like honey to the market as a food product is pretty straightforward but for medicines the bar is set higher.
The main culprit Staph aureus lives on our skin and can cause infection around catheters used during treatment of dialysis-related infections.
A total of 371 trial participants undergoing dialysis received either standard antibiotic therapy to prevent infection
This is important because diabetes is the leading cause of kidney failure so any therapy should work with normal and diabetic kidney dialysis patients.
We can conclude that honey therapy instead of antibiotics at least does no harm for many dialysis patients but also that it s not good for diabetics.
or nutrition though the search is complicated by the dozens of different chemical types that may be combining to contaminate the pollen bees collect for their hives.
and fungicides ne pollen sample contained 21 different anthropogenic chemicals. According to the study which appeared in the open-access journal PLOS One the researchers discovered healthy bees that ate the fungicides which are supposedly harmless to bees were actually three times more likely to become infected with a parasite that's known to cause CCD than bees
not exposed to the chemicals. The study also indicated that there may not be a single cause of the collapse of bee colonies in North america the deaths may result from the impact of a complex web of chemicals spanning different types and classes of pesticides and fungicides.
Fungicides are used to control things like fungus on apples and weren't expected to have an impact on healthy bees.
Since the study has shown that bees eating such fungicides are much more likely to become infected with a deadly parasite USDA may need to change the way it regulates the use of those chemicals around crops
Likewise if CCD is linked to other components of the complex array of anthropogenic chemicals in pollen it will become even more difficult to protect bee colonies not to mention the other forms of life subjected to those chemicals as they spread through the food web and the broader environment.
and other chemicals that bees in an agricultural setting are exposed to. CCD isn't just about the bees food crops
and it would make sense that chemicals designed to kill certain things like pests or weeds might also have unintended consequences when combined and later spread outside crops.

but those regulations don't apply to the chemicals used to kill fungus on the crops as those substances were thought to be harmless to bees.
