This one is eating a coffee tree. Maybe that's the secret. Â--The latest finding in the world's  bottomless cup of coffee studies reveals that the drug helps us remember things.
Johns hopkins university in Baltimore  observed that people who took a caffeine pill scored higher on memory tests than did swallowed those who a dummy tablet, the BBC reportsâ in a summary of an article in Nature Neuroscience.
Caffeine, of course, is the stimulant found in coffee and tea. The research team did not administer beverage.
Our study suggests that 200mg of coffee is beneficial to those who do not regularly ingest caffeine.

At certain points in time you might want to prune trees. We do the harvesting in the hot months down here.
You put some Southern yellow pine in the ground, which is on a 60 to 70-year rotation.
so we take some mature trees out and let younger ones stand. How many trees do you have?
These days when we plant seedlings, we plant on the order of about 600 trees per acre.
So you calculate that, and factor in for taking some out. What the thing you want everyone to understand about trees?
It important for people to understand that trees are a natural, organic and renewable resource and a remarkable resource.
It amazing what we get from our forests, and people don really think about it. Sure, we get lumber materials to make schools, churches, homes, books,
We use trees in so many ways. The cellulose, for instance, goes into everything from tires to chewing gum to salad dressing.
We just have to manage the trees properly. They don manage themselves. The Stones taking a bow at the 2006 Super bowl All this talk about trees

Knowing how tall the forests are will help scientists figure out how much carbon the trees can capture
So who has the tallest trees? From NASA: The new results show that temperate conifer forests--which are extremely moist
and contain massive trees such as Douglas fir, western hemlock, redwoods, and sequoias--have the tallest canopies, soaring above 131 feet.
In contrast, boreal forests dominated by spruce, fir, pine, and larch had canopies typically less than 66 feet.
Relatively undisturbed areas in tropical rain forests were about 82 feet tall, roughly the same height as the oak, beeches,
and birches of temperate broadleaf forests common in Europe and much of the United states. One puzzle Lefsky hopes to solve,
according to NASA, is what happens to 2 billion tons per year of missing carbon dioxide, considering that humans generate 7 billion tons
and the oceans and atmosphere only absorb five billion tons. A senior scientist at the Jet propulsion Lab, meanwhile--Sassan Saatchi--is relying on Lefsky's data to create forest biomass maps.

Sidewalk trees discourage city crime, study saysone of the things that bothers me most about my new home in Philadelphia is the lack of trees.
That's not to say there aren't any--there are plenty of big, leafy, deciduous trees all over my neighborhood.
Their shades of red, orange and yellow at this time of year are a stunning sight, and there's nothing quite like autumn in the northeastern United states. But my block?
Many trees were removed. Now, an otherwise leafy neighborhood filled with century-old homes has a decidedly barren bald spot.
 Researchers with the U s. Forest Service's Pacific Northwest and Southern Research Stations found that certain types of city trees may help lower property and violent crime rates.
The study--the first of its kind--looked at the effects of trees and other factors on crime in Portland
Most city officials know that the presence of trees helps resist the heat island effect of a dense city,
large trees--the kind I'm missing on my block--were associated with a reduction in crime.
Skinny, small trees? An increase in crime. Using crime data from the Portland Police Bureau from 2005 to 2007,
and yard trees and the number of trees growing on a lot had the most effect on crime occurrence.
We believe that large street trees can reduce crime by signaling to a potential criminal that a neighborhood is cared better for and, therefore
Large yard trees also were associated with lower crime rates, most likely because they are less view-obstructing than smaller trees.
Meanwhile, small yard trees may actually increase crime because they provide cover for criminals, the researchers suggest.
Without a doubt, the study is limited, and the researchers say they plan to replicate it in other cities before drawing any grand conclusions.
The trees can even be used to collect rainwater. Electricity is generated by a built-in solar photovoltaic system that converts energy from sunlight during the day hours.

Scientists say they have determined the complete DNA sequence of the tree that produces cocoa beans, an accomplishment that is expected to vastly accelerate efforts to assure a stable supply of chocolate
The candy maker Mars is expected to announce on Wednesday that a project it financed has completed essentially the raw sequence of the genome of the cacao tree,
could help in breeding trees that have higher yields and are more resistant to diseases.
The tree, known officially as Theobroma cacao (meaning oefood of the gods), contains about 420 million DNA units, represented by the letters A c, G and T. That is fairly small for a plant.

including modified trees that are better than natural ones at absorbing carbon dioxide, and termites that can eat old cars.
I soon focused on the potent antidiabetic herb, Pterocarpus marsupium. Crude extracts of Pterocarpus marsupium (Indian keno tree) bark naturally have high concentrations of pterostilbene (more than 4%by weight
and extraction can get this level much higher) and have been used as a traditional herbal treatment for diabetes in India for thousands of years.
As an herbal medicine, Pterocarpus marsupium is popular in India for its diverse health benefits. Besides diabetes, the herb is reported also to cure a wide spectrum of ailments like skin diseases, fractures, bruises, constipation, hemorrhages, and rheumatoid arthritis.
These diverse health benefits of Pterocarpus marsupium make it a clear favorite to include in a preventive herbal cocktail along with Astragalus.
Most of the research and commercial success with proanthocyanidins has come from extracts of a French maritime pine bark called Pycnogenol (65 to 75%proanthocyanidins) and various grape seed extracts (80-90%proanthocyanidins.
These diverse health benefits make Pine Bark proanthocyanidins another perfect candidate to combine with wide-spectrum herbal extracts from Astragalus membranaceus and Pterocarpus marsupium bark.
and sustainably using stem cells derived from trees, a study suggests. Researchers have isolated and grown stem cells from a yew tree
whose bark is a natural source of the anticancer compound paclitaxel. The development could enable the compound to be produced on a commercial scale at low cost, with no harmful by-products.
an extract from yew tree bark is used to industrially manufacture the compound paclitaxel. However, this process is expensive,
requires supplies of mature trees, and creates environmentally damaging by-products. Researchers claim that using stem cells self-renewing tree cells
which can be manipulated to produce large amounts of the active compound would effectively create an abundant supply of the drug.
What about tree power? It turns out that it's there, in small but measurable quantities.
There's enough power in trees for University of Washington researchers to run an electronic circuit,
As far as we know this is the first peer-reviewed paper of someone powering something entirely by sticking electrodes into a tree,
The UW team sought to further academic research in the field of tree power by building circuits to run off that energy.
They successfully ran a circuit solely off tree power for the first time. Co-author Carlton Himes, a UW undergraduate student,
Hooking nails to trees and connecting a voltmeter, he found that bigleaf maples, common on the UW campus, generate a steady voltage of up to a few hundred millivolts.
The UW team next built a device that could run on the available power. Co-author Brian Otis,
and currents that we get out of a tree. But the nanoscale is not just in size,
The tree-power phenomenon is different from the popular potato or lemon experiment, in which two different metals react with the food to create an electric potential difference that causes a current to flow."
Tree power is unlikely to replace solar power for most applications, Parviz admits. But the system could provide a low-cost option for powering tree sensors that might be used to detect environmental conditions or forest fires.
The electronic output could also be used to gauge a tree's health.""It's not exactly established where these voltages come from.
But there seems to be some signaling in trees, similar to what happens in the human body but with slower speed,
"Parviz said.""I'm interested in applying our results as a way of investigating what the tree is doing.
