Vanderbilt University researchers have discovered that engineered probiotic bacteria (“friendly” bacteria like those in yogurt) in the gut produce a therapeutic compound that inhibits weight gain, insulin resistance, and other adverse effects of a high-fat diet in mice.

“Of course it’s hard to speculate from mouse to human,” said senior investigator Sean Davies, Ph.D., assistant professor of Pharmacology. “But essentially, we’ve prevented most… read more

Study Supports the Long-Term Benefits and Safety of Transcranial Magnetic Stimulation for Depression

October 13, 2010

In a study to determine the durability and long-term effects of transcranial magnetic stimulation (TMS), psychiatric researchers at Rush University Medical Center have found the non-invasive, non-drug therapy to be an effective, long-term treatment for major depression.

TMS therapy is a non-invasive technique that delivers highly focused magnetic field pulses to a specific portion of the brain, the left prefrontal cortex, to stimulate the areas… read more

Study Supports View That Ice Age Is Still Quite a Way Off

June 11, 2004

A group of climate and ice experts says it has new evidence that Earth is not even halfway through the current warm era.

The evidence comes from ice extracted from Antarctica, composed of thousands of ice layers formed as each year’s snowfall was compressed over time. It reveals many similarities between today’s atmospheric and temperature patterns and those of a prolonged warm interval that took place 430,000 years ago.

Study Ties Genetic Variations to Schizophrenia

March 31, 2008

A new study has found that rare and previously undetectable genetic variations may significantly increase the risk that a person will develop schizophrenia.

One of the mutations identified in the study, for instance, distorts a protein that is involved in guiding neurons to their proper places during brain development. Another mutation that turned up changes the shape of a molecule that transports glutamate, a chemical that excites neurons and… read more

Study to determine whether fish oil can help prevent psychiatric disorders

February 9, 2012

Researchers at Zucker Hillside Hospital’s Recognition and Prevention (RAP) Program who have worked with teenagers at risk for serious mental illness for the past decade are now studying the effectiveness of Omega 3 fatty acids (such as fish oil) for treating psychiatric symptoms.

This new study is a National Institute of Mental Health-funded randomized double-blind trial that was designed to test whether Omega-3 fatty acids… read more

Light stimulates brain activity during a cognitive task even in some people who are totally blind, according to a study conducted by researchers at the University of Montreal and Boston’s Brigham and Women’s Hospital.

“We were stunned to discover  that the brain still responds to light in these rare three completely blind patients  despite having absolutely no conscious vision at all,” said senior co-author Steven… read more

Study Zeroes In on Calories, Not Diet, for Loss

February 26, 2009

People lose weight if they lower calories — it doesn’t matter which diet, according to the largest-ever controlled study of weight-loss methods, published Wednesday in The New England Journal of Medicine.

Study, in a First, Explains Evolution’s Molecular Advance

April 7, 2006

By reconstructing ancient genes from long-extinct animals, scientists have for the first time demonstrated the step-by-step progression of how evolution created a new piece of molecular machinery by reusing and modifying existing parts.

The researchers say the findings, published today in the journal Science, offer a counterargument to doubters of evolution who question how a progression of small changes could produce the intricate mechanisms found in living cells.

Study: Chip-Tools Spending To Double

July 13, 2004

The semiconductor-tools industry is poised for dramatic growth in 2004, according to a new report from research firm Gartner. Demand is being driven by a seemingly insatiable consumer appetite for electronics devices, such as cell phones.

Worldwide semiconductor capital spending is on pace to reach US$44.8 billion this year, growing 50.9 percent from 2003, according to Gartner. Capital equipment spending is forecast to grow 63.5 percent in 2004.… read more

Study: Digital universe and its impact bigger than we thought

March 12, 2008

IDC estimates that by 2011 there will be 1,800 exabytes of electronic data in existence (an exabyte is 1 billion gigabytes), at a compound annual growth rate of almost 60 percent from 2006.

IDC created a “Personal Digital Footprint Calculator” ticker, which counts the estimated amount of data created second by second.

Study: Fat or thin–one gene does it?

October 7, 2003

A gene in different versions may determine whether people are predisposed to being obese or thin, say researchers at Icelandic biotechnology company deCODE genetics Inc.

The finding is the result of analysis of DNA from more than 1,000 Icelandic women.

Study: Internet could run out of capacity in two years

November 20, 2007

A flood of new video and other Web content could overwhelm the Internet by 2010 unless backbone providers invest up to US$137 billion in new capacity, more than double what service providers plan to invest, according to a study by Nemertes Research Group.

Internet users will create 161 exabytes (quintillion bytes) of new data this year, they said.

The study is the first to “apply Moore’s Law (or… read more

Study: Low-carb diet best for weight, cholesterol

July 17, 2008

A low-carb diet and a Mediterranean-style regimen helped people lose more weight than a traditional low-fat diet in one of the longest and largest studies to compare the dueling weight-loss techniques.

The study was conducted by researchers at Ben-Gurion University of the Negev and will be published Thursday in the New England Journal of Medicine.

The low-fat diet — no more than 30 percent of calories from fat… read more

Study: Nanoelectronics market to reach $75B by 2014

April 22, 2004

“Nanotechnology: Impact of Nanotechnology on the U.S. Electronics Industry” predicts the nanoelectronics market will grow more than 45 percent during the next 10 years to more than $75 billion.

The study divides the market into first-generation products, which include nanotubes and nanowires, expected to emerge within the decade,; and second-generation, which includes molecular electronics, quantum computing and self-assembled electronic devices, which will not emerge for at least 10 years.

Study: Self-replicating nanomachines feasible

June 4, 2004

A useful self-replicating machine could be less complex than a Pentium IV chip, according to a new study of of “kinematic cellular automata” performed by General Dynamics for NASA.

Through simulations, the researchers demonstrated the feasibility of this kind of self-replication, which could in a decade or more lead to the mass manufacture of molecularly precise robots, display monitors and integrated circuits that can be programmed in the field,… read more
