Brain Waves: How Neuronal Activity Is Timed In Brain's Memory-making Circuits
http://feeds.sciencedaily.com/~r/sciencedaily/~3/r8uhhKTnLhY/090529132121.htm
Theta oscillations are a type of brain rhythm that orchestrates neuronal activity in the hippocampus, a brain area critical for the formation of new memories. For several decades these oscillations were believed to be "in sync" across the hippocampus, timing the firing of neurons like a sort of central pacemaker. Researchers show that instead of being in sync, theta oscillations sweep along the length of the hippocampus as traveling waves.

Genetic Profiling Reveals Genes Active In The Earliest Brain Circuit Construction
http://feeds.sciencedaily.com/~r/sciencedaily/~3/Tt-xK4agLA8/090530173757.htm
Long before the brain's neurons can facilitate life's big decisions, they have to find their own destiny in the rapidly developing embryo. In the lingo of neurobiologists, they are "fated" very early on to become certain types of cells, over time traveling to and organizing the various structures that compose the brain. These earliest developments are difficult to observe, like the first few moments in the life of the universe following the Big Bang. But by adapting new tools of genetic profiling, researchers have peered into the brain as it's born and teased out genes that shape its aboriginal fate.

Picosecond Oscilloscope
http://feeds.sciencedaily.com/~r/sciencedaily/~3/i_f4TWGQlM0/090526163014.htm
An oscilloscope is a device for displaying signals that are too fast to be seen by the human eye. Typically the signal consists of a voltage level that changes quickly moment by moment (over millisecond to nanosecond timescales). What is seen on the screen of the scope is a waveform whose value is graphed along the vertical axis as a function of the horizontal axis representing time. An electron beam, aimed at a phosphorescent screen, is swept horizontally providing a light-trace on the screen while, coincidentally, the instantaneous voltage of the input signal is used to deflect the electron beam up or down, creating the visible trace.

For Different Species, Different Functions For Embryonic MicroRNAs
http://feeds.sciencedaily.com/~r/sciencedaily/~3/2ep0SnRk8o4/090522171001.htm
When evolution has lucked into efficient solutions for life's most fundamental problems, it adopts them as invaluable family heirlooms, passing them down as one species evolves into another. So it was reasonable to expect that a key regulator of embryonic development -- a strand of RNA that shepherds stem cells through the process of differentiation -- might play the same role in all vertebrates, from fish to people. New research, however, has shown that when it comes to microRNAs, what works for one animal may not work the same way in another.

How Does The Human Brain Work? New Ways To Better Understand How Our Brain Processes Information
http://feeds.sciencedaily.com/~r/sciencedaily/~3/6rDrytqeass/090519152559.htm
How does the human brain process information? Researchers explore new methodologies that shed light on this age-old mystery. The human brain is perhaps the most complex of organs, boasting between 50-100 billion nerve cells or neurons that constantly interact with each other. These neurons 'carry' messages through electrochemical processes; meaning, chemicals in our body (charged sodium, potassium and chloride ions) move in and out of these cells and establish an electrical current.

Buckyball Computer Simulations Help Team Find Molecular Key To Combating HIV
http://feeds.sciencedaily.com/~r/sciencedaily/~3/9bljOlX5gbE/090519134839.htm
Researchers have identified specific molecules that could block the means by which HIV -- the deadly virus that causes AIDS -- spreads by taking away its ability to bind with other proteins. Computer simulations were used to test more than 100 carbon fullerene, or "buckyball," derivatives initially developed for other purposes to see if they could be used to inhibit a strain of the virus, HIV-1 PR, by attaching themselves to its binding pocket.

Knowledge Of Epigenetics Helps Scientists Develop Tool To Study Deadly Parasite’s Histone Code

In the Japanese art of paper folding, a series of folds can make the same sheet of paper into a ballerina or baby elephant. But try unfolding the baby elephant and making it into a ballerina. It's like trying to make a neuron from a kidney cell. Epigenetics, it turns out, isn't much different from this old Japanese art: Each fold, or epigenetic crease, both limits and permits further potential folds in a way that mirrors how epigenetic changes seal a cell's fate.

Fathers Respond To Teens' Risky Sexual Behavior With Increased Supervision
http://feeds.sciencedaily.com/~r/sciencedaily/~3/zKMv3BLDYRg/090515083700.htm
Findings from a study following more than 3,200 teenagers over a period of four years show that fathers react differently than mothers to their children's sexual behavior. When teens engaged in risky sexual behavior, instead of parents becoming less involved, as previously seen, fathers actually boosted their involvement, learning more about their children's friends and activities. This study also identified involvement in family activities as a protective force.

Plastic That Grows On Trees
http://feeds.sciencedaily.com/~r/sciencedaily/~3/N_WjBVTI95A/090519134837.htm
To turn plants into a renewable, nonpolluting replacement for crude oil, scientists have to learn how to convert plant biomass into a building block for plastics and fuels cheaply and efficiently. In new research, chemists have successfully converted cellulose -- the most common plant carbohydrate -- directly into the building block called HMF in one step. This simple process generates a high yield of HMF and allows the use of raw cellulose as feed material.

New Target To Combat Cancer? Defects In Pathway Underlying Fanconi Anaemia Can Cause Cancer In Non-FA Patients
http://feeds.sciencedaily.com/~r/sciencedaily/~3/4t29fGk70IY/090514084119.htm
In patients with Fanconi anaemia (FA), one of the DNA repair mechanisms that normally protects us against cancer no longer works adequately. A Dutch researcher set out to find the genes responsible for this defect. He discovered a new FA gene and established that FA gene defects could also cause cancer in people who do not suffer from FA. Although this does not sound positive, it is in fact good news. That is because cells with a FA defect are hypersensitive to certain types of chemotherapy and can therefore be specifically targeted.

http://feeds.sciencedaily.com/~r/sciencedaily/~3/zVfyNjaGScU/090513173501.htm
Surgical removal of a tissue sample is now the standard for diagnosing cancer. Such procedures, known as biopsies, are accurate but only offer a snapshot of the tumor at a single moment in time. Monitoring a tumor for weeks or months after the biopsy, tracking its growth and how it responds to treatment, would be much more valuable. Now researchers report the first implantable device that can do just that.

Many molecular materials, be they hydrogen for fuel cells or drugs, can be stored in metal-organic frameworks (MOFs). This would even be possible for metal nano particles for catalysis, were there not one little hindrance: if the void spaces in the MOF are too large, a second embedded framework system automatically develops during the synthesis process. Scientists can now grow it layer-by-layer on an "intelligent" organic surface. This enables the formation of voids that are large enough for metal particles.

Pollination Crisis 'A Myth': Honeybees Are On The Rise, But Demand Grows Faster
http://feeds.sciencedaily.com/~r/sciencedaily/~3/uYkQkxgGGX0/090507121949.htm
The notion that a decline in pollinators may threaten the human food supply -- producing a situation that has been referred to as a "pollination crisis" -- can be considered a myth, at least where honeybees are concerned, researchers report. First of all, most agricultural crop production does not depend on pollinators. On top of that, while honeybees may be dwindling in some parts of the world, the number of domesticated bees world-wide is actually on the rise, their new report shows.
