Scientists develop ‘brain chip’

March 12, 2003

USC researchers are developing the first brain prothesis, an artificial hippocampus to replace damaged brain tissue.

Scientists will initially test the “brain chip” on rat brains. The silicon-chip programming was developed by stimulating slices of rat hippocampus with electrical signals millions of times to determine which input produced a corresponding output. The chip would translate activity coming from the rest of the brain and send the necessary output instructions… read more

Scientists Develop Financial Turing Test

February 26, 2010

Humans can reliably distinguish between real and random market data, researchers at AlphaSimplex, MIT’s Sloan School of Management, and NorthEastern University found in an experiment.

Anyone can take the “financial Turing test” on their website.

Scientists develop fluorescent proteins for live cell imaging, biosensor design

February 7, 2008

Carnegie Mellon University scientists have developed a key component of a novel molecular biosensor technology–new “fluorogen activating proteins” (FAPs), which can be used to monitor biological activities of individual proteins and other biomolecules within living cells in real time.

Scientists Develop Nasal Spray That Improves Memory

October 2, 2009

A molecule from the body’s immune system (interleukin-6) administered through the nose helps the brain retain emotional and procedural memories during REM sleep, researchers from University of Lubeck in Germany have found.

Scientists develop new, more sensitive nanotechnology test for chemical DNA modifications

September 24, 2008

Johns Hopkins University School of Medicine researchers have developed a novel test to screen for chemical modifications to DNA known as methylation that could be used for early cancer diagnoses and assessing patients’ response to cancer therapies.

Scientists Develop Next-Generation Memory Chip

June 3, 2005

A team of international scientists has developed next-generation memory technology that is theoretically capable of makng a 10-nanometer-thick semiconductor.

Scientists Develop Novel Use Of Neurotechnology To Solve Classic Social Problem

September 14, 2009

Cal Tech economists and neuroscientists used whole-brain fMRI scans in an experiment to create a solution to the fundamental “public goods free-rider” problem (how to fairly rate the value of a public purchase or investment such as health care, given that people tend to undervalue it because they get benefit from it without paying more).

The subjects were asked to reveal how much they valued the good. If there… read more

Scientists develop protein nanoarrays for biological detection

February 11, 2002

Scientists at Northwestern University have developed a new detection technology on the nanometer scale that could lead to the next generation of proteomic arrays and new methods for diagnosing infectious diseases and biological weapons.
The researchers utilize a process invented at Northwestern’s Institute for Nanotechnology called Dip-Pen Nanolithography to make arrays of proteins with features more than 1,000 times smaller than those used in conventional arrays. This leads to nanoarrays… read more

Scientists Develop Tool to Probe Role of Oxidative Stress in Aging, Disease

February 18, 2008

University of Michigan researchers have a new technique to observe how oxidative stress affects proteins, allowing them to quantify the oxidation state of thousands of different proteins in a single experiment.

Scientists develop universal DNA reader to advance faster, cheaper sequencing efforts

February 12, 2010

As a single chemical base of DNA (blue atoms) passes through a 2.5nm gap between two gold electrodes, it momentarily sticks to the electrodes (purple bonds) and a small increase in the current is detected, with a unique signature for each of the four DNA bases (Biodesign Institute at Arizona State University)

Arizona State University scientists have developed a nanoscale DNA reader that may lead to performing DNA sequencing faster than current technology and at a fraction of the cost.

Scientists developing clean energy systems from micro-algae

October 9, 2007

An international consortium established by Associate Professor Ben Hankamer at The University of Queensland is developing a clean source of energy that could see some of our future fuel and possibly water needs being generated by solar-powered bioreactors and microalgae while absorbing CO2.

Scientists digitally mimic evolution to create novel proteins

May 10, 2016

SEWING method-ft

Here’s an innovative idea: create new proteins by simply “sewing” together pieces of existing proteins. That’s exactly what researchers at the University of North Carolina School of Medicine have done to design new “cellular machines” needed to understand and battle diseases.

Published today in the journal Science, the new technique, called SEWING, was inspired by natural evolutionary mechanisms that also recombine portions of the 100,000 different known… read more

Scientists discover largest structure in universe

October 27, 2003

Scientists have discovered the largest structure yet found in the universe, a “Great Wall” of galaxies 1.37 billion light-years long, according to an article in Science, Oct. 24, 2003.

This cosmic ribbon dwarfs anything seen before by more than 600 million light-years. The wall’s vastness pushes the limits of existing cosmological theories.

Scientists discover 21st century plague

November 24, 2008

Bacteria that can cause serious heart disease in humans are being spread by rat fleas, sparking concern that the infections could become a bigger problem in humans.

Brown rats, the biggest and most common rats in Europe, may now be carrying the bacteria.

Scientists discover a controller of brain circuits

December 29, 2009

A Johns Hopkins neuroscientist has found that semaphorin proteins regulate the number of synapses and their distribution in the part of the brain involved in conscious thought, which could have an impact on how scientists think about the early origins of autism, schizophrenia, epilepsy and other neurological disorders.
