Like finally seeing all the gears of a watch and how they work together, researchers from UCLA and UC Berkeley have, for the first time ever, solved the puzzle of how the various components of an entire telomerase enzyme complex fit together and function in a three-dimensional structure.
The creation of the first complete visual map of the telomerase enzyme, which is known to play a significant role in aging and most cancers, represents a breakthrough that could open up a host of new approaches to fighting disease, the researchers said. (more…)
With the 2015 sesquicentennial of Abraham Lincoln’s death approaching, interest is rising, and with new tools, UA researchers have turned their attention to one of the last remaining mysteries about what reportedly was the largest traditional funeral in American history – the train’s color.
A trove of information exists about Abraham Lincoln’s funeral, which drew millions of mourners during a two-week railway procession across the Northern states.
But until now, the precise color of the president’s railcar had been lost to history. (more…)
Decreasing emissions of black carbon, methane and other pollutants makes a difference
With coastal areas bracing for rising sea levels, new research indicates that cutting emissions of certain pollutants can greatly slow sea level rise this century.
Scientists found that reductions in four pollutants that cycle comparatively quickly through the atmosphere could temporarily forestall the rate of sea level rise by roughly 25 to 50 percent.
The researchers focused on emissions of four heat-trapping pollutants: methane, tropospheric ozone, hydrofluorocarbons and black carbon. (more…)
Read the improbable story of a Microsoft employee who twice turned down a traditional tech sector job so he could teach high school students, and then landed his dream job.
REDMOND, Wash. — Kevin Wang could have followed his career.
Instead, he chose to follow his calling.
It was the early 2000s, and Wang had just graduated from Berkeley with a degree in computer science and electrical engineering. He was trying to decide which tech company he should offer his services to, when a high school came calling. (more…)
COLUMBIA, Mo. — Crocodilians have nerves on their faces that are so sensitive, they can detect a change in a pond when a single drop hits the water surface several feet away. Alligators and crocodiles use these “invisible whiskers” to detect prey when hunting. Now, a new study from the University of Missouri has measured the nerves responsible for this function, which will help biologists understand how today’s animals, as well as dinosaurs and crocodiles that lived millions of years ago, interact with the environment around them.

Ecologists are wary of non-native species, but along the shores of Cape Cod where grass-eating crabs have been running amok and destroying the marsh, an invasion of a predatory green crabs has helped turn back the tide in favor of the grass. The counter-intuitive conclusions appear in a new paper in the journal Ecology.
PROVIDENCE, R.I. [Brown University] — Long vilified, invasive species can sometimes become an ecosystem asset. New Brown University research published online in the journal Ecology reports exactly such a situation in the distressed salt marshes of Cape Cod. There, the invasive green crab Carcinus maenas is helping to restore the marsh by driving away the Sesarma reticulatum crabs that have been depleting the marsh grasses. (more…)
The adolescent age is very much critical phase of life. Every teenage girl and boy when they enter in this age tends to behave differently, which has to be understood very well by the parents, elders and teenagers. This can help everyone including the teenager to grow in a healthy atmosphere, which can help them to imbibe positive values in their lives along with averting them to tread wrong paths. If you fail to understand people of this age, you may end up seeing your adolescent boy or girl going in a wrong direction. Hence knowing the dos and don’ts are important both for parents and teenagers as well. Let’s check out the do’s and don’ts evident in this critical phase of life.(more…)
Unlike most organisms, they don’t need iron, but they crave manganese
Scientists have confirmed that the pathogen that causes Lyme Disease—unlike any other known organism—can exist without iron, a metal that all other life needs to make proteins and enzymes. Instead of iron, the bacteria substitute manganese to make an essential enzyme, thus eluding immune system defenses that protect the body by starving pathogens of iron.
To cause disease, Borrelia burgdorferi requires unusually high levels of manganese, scientists at Johns Hopkins University (JHU), Woods Hole Oceanographic Institution (WHOI), and the University of Texas reported. Their study, published March 22, 2013, in TheJournal of Biological Chemistry, may explain some mysteries about why Lyme Disease is slow-growing and hard to detect and treat. The findings also open the door to search for new therapies to thwart the bacterium by targeting manganese. (more…)
