Instead of being in sync, theta oscillations actually sweep along the length of the hippocampus as traveling waves.
Slicing chromosomes leads to new insights into... →
Hunt’s group hypothesized that polar ejection forces should be proportional to the chromosome’s size, and therefore could be predictably changed by altering the size of the chromosomes. Using newts…

Technology Review: Faster Internet on the Road →
R2D2 calculates this balance between diversity and directionality, coordinates between multiple base stations, and maintains an optimizing database—all of which speed up data transfers.

Radio wave erase pre-cance cells in esophagus →
Heat generated by high frequency radio waves conducted through a catheter erases most pre-cancerous cells associated with chronic acid reflux, providing an lower-cost (10:1) alternative to surgery.
Your Body Is a Wonderland ... of Bacteria --... →
The researchers found about 1000 species total, which were fairly consistent from person to person; it turns out we all have similar tenants in our noses and on our backs. The number suggests that…

The Technium: Increasing Ubiquity →
Whereas it took electrification 45 years to reach 90% of US residents, it’s taken only 20 years for cell phones to reach the same penetration. The rate of diffusion is accelerating. A straight line…

CAPE (Context Aware Protocol Engines) came out of several lines of work related to wireless ad hoc networking.
stackvm - Google Code →
The goal of this project is to create a distributed parallel object-oriented stack based VM that converts stack instructions to native machine code on the fly. The first target architectures will be…
Beam me up Scotty. Materials; check. Template; check. Spot Welder; check. Parabolic dish assembly tomorrow.

Half of your friends lost in seven years →
Only thirty percent of the discussion partners and practical helpers still held the same position seven years later. Only 48 percent were still part of the network. With his research Mollenhorst has…

Having a really negative reaction to Google Wave. I think I’m sea sick.
Electromagnetic receptors in humans? « Brains Lab →
Using EEG, Marino et al evaluated the likelihood of a magnetic stimuli evoking a post-transduction action potential in ten human subjects. Even with only a 10 ms rise time and a 0.2 ms fall time,…
The evolution of gene regulation →
“use-it-or-lose-it” principle: if genes are frequently active, then, as a rule, they will be directly induced. Genes that encode more rarely used proteins, on the other hand, tend to be kept inactive…

Evidence of macroscopic quantum tunneling detected... →
This research observes a process called a quantum phase slip, whereby packs of roughly 100,000 electrons tunnel together from higher electrical current states to lower ones. The energy locked in the…

The VIA VX855 MSP integrates a high performance DDR2 memory controller, a 400/800 MHz FSB processor interface, and extensive I/O capabilities (such as 6 x USB 2.0, SDIO, UART, SPI, LPC and SMBus) in…
Interview with Mitch Bradley - Firmware - OLPC →
We have had endless fights trying to solve difficult problems in those areas where we can’t see the code. So I would say that one of our biggest development challenges has actually been dealing with…
