so they designed a hat containing a material that captured their odorous molecules and placed them on the goats for a week to collect the scent.
Analysis of the gases collected identified a range of compounds, many of which were unknown and were not present in castrated males.
But one molecule stood out: 4-ethyloctanal, a chemical not previously found in nature and that has an orangy, floral odour.
Scientists use molecular clock models of evolution to piece together relationships among organisms by tracking genetic mutations over time.
Some models assume the rates of molecular evolution are roughly equal but there is evidence that the influenza virus evolves at different rates in different hosts faster in birds than in horses, for example.

Even a pine tree burned in a forest fire does not release as much carbon as a pine tree burned in a power plant Niel Lawrence a National Resources Defense Council lawyer told Greenwire.
We pump BILLIONS of tons of carbon into the air annually. This is carbon that does not exist in a natural cycle.
We're taking it from well below the surface and putting it into the air.
Also they periodically hand the vehicle back to the carbon based life form. I don't disagree with the approach I'm just saying that many things are yet to be proven.
) particles penetrating the earth's atmosphere. Svensmark's theory which pitted him against today's mainstream theorists who claim carbon dioxide (CO2) is responsible for global warming involved a link between the earth's magnetic field
and climate since that field helps regulate the number of GCR particles that reach the earth's atmosphere.
they happen when patches of iron atoms in Earth's liquid outer core become reverse-aligned like tiny magnets oriented in the opposite direction from those around them.
Some of the particles associated with CMES can be blocked by Earth's magnetic field. With a weak field this shielding is less efficient.

Ozone holes like that over Antarctica (which today are due to an entirely different cause related to man) could form as solar particles interact with the atmosphere in a cascade of chemical reactions.
and protects us from the sun's charged particles and cosmic rays by focusing them towards the poles.
There is a growing body of evidence that the sun's highly charged particles batter the upper atmosphere so hard that some of the assault filters down into the atmosphere around us influencing the wind atmospheric pressure and temperature.
Without our magnetic shield those solar particles might create havoc with the weather. That cosmic radiation blasting the Earth's surface could cause genetic mutations and cancers.
American oak imparts the whisky with compounds such as esters lactones and phenols. One such compound known colloquially as whisky lactone produces a strong coconut flavor in the finished dram.
Vanillin another compound extracted from the oak unsurprisingly contributes an aroma of vanilla. But because freshly charred oak has high levels of these aromatic compounds casks made from it can overpower the more delicate flavors of a Speyside malt.
Instead Glenfiddich uses barrels that have contributed already much of the wood's flavoring compounds to American bourbon.
The result is balanced a elegantly dram with notes of warm crunchy toffee marmalade on toast

As for the free carbon acidifying the ocean why would that be worrying? The acidity is neutralized by the dissolution of Calcium

There are also some pretty convincing signs that the'excess'carbon is SURFACE carbon not from fossil fuels.
but if you look at carbon 14 in the atmosphere prior to extensive nuclear test you'd expect the percentage to drop as fossil carbon (without 14c) is introduced into the atmosphere
People and livestock (pigs chickens cows) are the most likely source of the majority of the carbon increase.
because it doesn't fit the agenda it is carbon neutral (only affects the'flow'of carbon
When this happens the result is in the opposite direction from that of trapped ions

Key to this process is carbon sequestration. Plants sequester some of the carbon dioxide they breathe in storing it in their branches
To turn deserts into a viable spot for carbon sequestration the researchers assembled a diverse team of specialists with knowledge ranging from irrigation and carbon sequestration to desalination and economics.
Short poisonous and hardy the Jatropha curcas tree can survive severe heat poor and alkaline soil and very low rainfall.
and then letting the plants start sequestering carbon and eventually producing biofuel. A potential unintended side-effect of such a project is a chance of increased cloud cover and rainfall.
it's out there combating climate change a few carbon emissions at a time. When beavers build a dam impeding the natural flow of water the river begins to overflow more often creating a sediment-rich wetland area known as a beaver meadow.
A new study from Colorado State university geology professor Ellen Wohl finds that these beaver meadows store carbon temporarily sequestering greenhouse gases from the atmosphere.
With reductions in the beaver population we're missing out on a whole lot of potential carbon storage.
Wohl found that the abandoned beaver dams she studied made up around 8 percent of the carbon storage in the landscape
Squirreling away our carbon log by log. The study appears in Geophysical Research Letters. Science via Phys. org Considering we're at a critical carbon deficit right now it's about time to start wiping these pudgy menaces out for good!
I'm a little skeptical about this study. I have a hard time believing that cutting down trees
and burying them in water will have a net negative impact on the level of carbon in the area.
You're reducing a carbon sync AND anaerobic decomposition as you would get with buried plant matter would produce methane which is a much more potent greenhouse gas than CO2.
but I'd bet there is a net increase of atmospheric carbon. Cute Beaver and interesting article too.
Critical carbon deficit? WTF are you talking about?@@Frosttty for most of the history of the world we have had significantly more atmospheric carbon than we do now.
Most of it has already been buried. Atmospheric carbon has been falling since the late Jurassic when it was about 2500 ppm vs today's 400 ppm.
Considering the climate stabilizing properties of greenhouse gasses and the importance of CO2 to life On earth we need to do everything we can to prevent carbon sequestration
if we desire a healthy planet. As a retired Department of Environmental Quality Employee and an owner of timber land this is a stupid article on environmentalism gone crazy in past history.
Reading some of these comments it's clear that it's not enough that beavers sequester carbon raise the water table augment the density

In addition the human form of one protein is blocked by the lipid-lowering drug clofibrate perhaps linking this and related compounds to the rising global incidence of human infertility...
#Carbon Test Determines Whether A Piece Of Ivory Is Legal Or Illegalone way poachers get the big elephants they want is by shooting a baby elephant first.
The technique looks at the radioactive carbon in the ivory which elephants and every other living creature on earth incorporated into their bodies in unusually high levels during the Cold War era.
The carbon tells scientists whether a piece of ivory comes from an elephant that died before
and geologists from the U s. Kenya and the U k. use mass spectrometry to determine the amount of carbon-14 a rare radioactive isotope of carbon appears in an animal tissue.
There's always some carbon-14 in the atmosphere but during the Cold war aboveground nuclear tests doubled the amount of carbon-14 in the environment.
Plants incorporate carbon into their roots stems and leaves as they grow. Animals then get that carbon from eating plants
or eating animals that eat plants. Other research groups have used the Cold war spike in carbon-14 to figure out the birthdates of human brain cells fat cells and teeth.
The ivory group tested many animal tissues this way including hippopotamus teeth elephant tail hairs and blue monkey hairs in addition to elephant tusks and rhino horns.
For tissues formed after 1955 the scientists are able to pin down a death date that's within 0. 3 to 1. 3 years of the animal's actual death.
It seems that he's following through pledging in his three-pronged plan to cut carbon pollution prepare communities
The main tenant of the new plan involves setting federal standards limiting carbon pollution from both new and existing power plants
and lead but there is no federal rule to prevent power plants from releasing as much carbon pollution as they want the plan states.
And while Obama called for America to lead by example when it comes to combating climate change carbon pollution is rapidly rising in developing countries he noted.
only if this project does not significantly exacerbate the problem of carbon pollution. Because we typically all agree with what the government thinks is in our nation's best interest.
By the way Ms. Ferro by carbon pollution do you mean carbon monoxide (CO) or carbon soot black carbon?
I really hope you have a beach housethe main tenant of the new plan involves setting federal standards limiting carbon pollution from both new and existing power plants
Does taking our advise mean popsci as a whole are agreeing to police carbon pollution? or maybe a few authors and the editor are in favor of carbon police.
A president's plan of action are political speeches that don't mean anything. They are used to placate appease a group of people like shaunacy ferro and her ilk for obvious reasons (money power beliefs etc.

#Using Wood As Biofuel May be Worse For The Planet Than We Thoughttimber harvesting may release significant amounts of carbon into the atmosphere according to a new study.
Analyses of carbon emissions often ignore the carbon stored in deep soils the study authors say.
But after reviewing multiple recent research papers about decreases in soil carbon levels the authors concluded that intensive forest management practices can cause large amounts of underground carbon to flow into the atmosphere.
Our paper suggests the carbon in the mineral soil may change more rapidly and result in increases in atmospheric carbon dioxide as a result of disturbances such as logging says Andrew Friedland a professor at Darthmouth College
Our paper suggests that increased reliance on wood may have unintended the effect of increasing the transfer of carbon from the mineral soil to the atmosphere.
Wait you're telling me that burning large amounts of wood and other biofuels puts carbon into the atmosphere?
and sustainably probably still has more benefits as a whole than burning fossil fuelsancient trees being burned currently release ancient carbon.
New trees being burned release recent aquired carbon. The ancient tree buring do to the age adds to the carbon foot print of Earth.
The burning of recently planted trees just cycles the same carbon as long as new trees are being planted.
Leave the trees that are 300 or more years old alone. http://www. popsci. com/technology/article/2013-05/iran-unveils-new-stealth-drone-isnt#comment-301696 LIKE A 1970 MARVEL TOY THERMIC

U f o)))when the tree rots release significant amounts of carbon into the atmosphere. that is what they not telling you. just replant all trees everything is good
. when the tree rots it will release significant amounts of carbon into the atmosphere. that is
Al gore owned a carbon exchange company (might still haven't checked) while he flew around the world in a private jet burning fossil fuel
but trees thenselves are carbon sinks. What's more we have huge swaths of desert land that can possibly be terriformed to lush greenland with smart engineering.
Second it would help to regulate atmospheric carbon as well as filter pollutants from the air. The thing is this has been known for decades.
If you cut down trees and sequester the wood (carbon) there will be NO release of CO2. I don't think anyone would argue that more trees is better than fewer trees
More carbon use by humans (access to cheap energy) is correlated directly to decreasing poverty and sickness. ppardee here's some more ammo for you.
Cutting down forests is carbon-neutral; it doesn't release carbon. But it clears the way for another tree to be planted in their place.
The tree itself is sequestered the Carbon that it breaths in. Move that CO2 pod out of the way to place a new sequestering machine to grow in its spot.
Then hide those CO2 pods in peoples'houses. They'll never suspect it! As far as the'global warming'issue ppardee and lauren have covered it pretty well.
I don't want tautologies such as It was the origin of the first self replicating molecule.

#Space Tourism's Black Carbon Problemthis story is part of a special Popularscience. com series on the future of energy.
The big threat from the scaling-up of space travel they say comes from something called black carbon a type of particulate matter that
when hurled into the stratosphere builds up for years absorbing visible light from the sun. According to one study black carbon emitted into the stratosphere by rockets would absorb 100000 times as much energy as the CO2 emitted by those rockets.
you don't want to put black carbon in the stratosphere. Period says Darin Toohey a professor of atmospheric and oceanic sciences at the University of Colorado Boulder.
***Black carbon should be familiar to anyone who's ever idled behind a diesel truck
The reason black carbon doesn't wreak more havoc on the environment is that it has a short lifetime in the lower atmosphere precipitation washes away black carbon emissions from planes and other sources within a matter of weeks.
They are also the only direct source of human-created compounds above 12 miles. Because there is no rain
or other atmospheric factors to wash out the black carbon in the stratosphere black carbon would linger for 5 to 10 years or more.
Moroever rockets produce over 1000 times more black carbon per unit of fuel than standard aircraft.
carbon effects of a hypothetical 1000 flight-per year industry. They measured the black carbon's radiative forcing âÂ#Âa metric for how much extra energy the Earth
and its atmosphere absorb from a given manmade or natural phenomena. The radiative forcing from the black carbon that rockets placed in the stratosphere was up to 100000 times greater than that of the CO2 released by the rockets.
In contrast the radiative forcing of the black carbon placed for just a few weeks into the atmosphere by jets is less than 1/10 of that of its carbon dioxide.**
***Here's where space tourism comes into play: The number of space launches annually around the world numbers around 70 today
That creates 1000 opportunities to shoot black carbon directly into the stratosphere. The amount of black carbon emitted during combustion On earth
or in the trophosphere where airlines fly tends to be low because of the relatively rich supply of oxygen.
Once you get into the stratosphere where low pressure leads to less oxygen black carbon can amount to as much as 5%of the products of combustion.
and deciding whether to grant licenses to launch vehicles into space says the effects of black carbon in the stratosphere are unclear.
Although black carbon is known to be a short-term climate forcer research on the potential climate change impacts of black carbon from rockets is in a very early stage
The space-tourism industry has downplayed black carbon's potential harm. Virgin Galactic declined repeated inquiries to comment.
So the concern about carbon or other particles is moot for us. Toohey still wants to see peer-reviewed studies of the actual interaction of XCOR and other engines with the stratosphere.
(or refute) the claims of particle-free emissions from combustion of any fuel in the upper atmosphere Toohey says.
and escapes into space launch the ion nuclear engines! If black carbon is such a problem why didn't they mention it during NASA flights?
Answer: they are worried only about private companies not the government. There's no satisfying climate scientists...
You can practically see the carbon output on that thing so much so the photo almost looks fake with the black shadows within the plume.
Black carbon in the upper atmosphere absorbs light from the sun. Said heated black carbon does not have any heating affects on the surface as heat rises.

the same shmucks who argue cow frts are making the world marm up also argue the carbon shifting by electric vehicles..
Now researchers have identified several compounds that help turn on those genes. They're present in honey something commercial bees don't get to keep--their food supply is taken for human use
Wenfu Mao and colleagues found three compounds in honey that increase the expression of a gene that helps bees metabolize pesticides.
By eating honey which contains pollen the bees are exposed to a compound that basically boosts their ability to break down dangerous chemicals.
Some aerosols--small atmospheric particles--can contribute to cooling because they help form clouds which reflect sunlight.
1. Eco-tourism will become a major source of revenue. 2. Investment in carbon sequestration by industrial nations looking to offset their CO2 production would also be a major source of revenue.
