Studio evolves from ‘Ice Age’ to ‘Robots’

June 10, 2003

20th Century Fox is planning to release the animated film Robots, due out in March 2005. It features a universe completely inhabited by mechanical people.

A relatively simple combination of naturally occurring sugars and amino acids formed on Earth before any life existed offers a plausible route to RNA, researchers at the University of California, Merced, have found.

Biological molecules, such as RNA and proteins, can exist as enantiomers. Enantiomers are two molecules that are identical except for the three dimensional arrangement of the atoms that make it up. One of the best… read more

Study claims 100 percent renewable energy possible by 2030

January 20, 2011

New research published in the journal Energy Policy says that enough renewable energy is available and could be harnessed to meet demand indefinitely by 2030 by building about four million 5 MW wind turbines, 1.7 billion 3 kW roof-mounted solar photovoltaic systems, and around 90,000 300 MW solar power plants.

Study details catastrophic impact of nuclear attack on US cities

March 21, 2007

A new study by researchers at the Center for Mass Destruction Defense (CMADD) at the University of Georgia details the catastrophic impact a nuclear attack would have on American cities and the inability of the nation’s current medical system to handle casualties.

It also suggests what the authors said are much needed yet relatively simple interventions that could save tens of thousands of lives.

Among the… read more

Study Details How U.S. Could Cut 28% of Greenhouse Gases

November 30, 2007

The United States could shave as much as 28 percent off the amount of greenhouse gases it emits at fairly modest cost and with only small technology innovations, according to a new report from McKinsey & Company.

The innovations include changes in the lighting, heating and cooling of buildings, for example, that would reduce carbon dioxide emissions from the burning of fossil fuels even as they save money.

Study Detects Recent Instance of Human Evolution

December 11, 2006

A surprisingly recent instance of human evolution has been detected among the peoples of East Africa. It is the ability to digest lactose, the principal sugar of milk, in adulthood, conferred by genetic changes that occurred as recently as 3,000 years ago, a team of geneticists has found.

Study establishes major new treatment target in diseased arteries

May 11, 2009

By eliminating the gene for a signaling protein called cyclophilin A (CypA) from a strain of mice, researchers at the University of Rochester and were able to provide complete protection against abdominal aortic aneurysm, a fatal event in 90 percent of cases.

Inhibition of CypA also appears to have benefit in several diseases that involve blood vessels in the brain and heart, the researchers suggest.

Study finds contaminants in bottled water

October 16, 2008

Laboratory tests on ten brands of bottled water purchased in nine states and the District of Columbia detected bacteria and 38 pollutants often found in tap water, some at levels no better than tap water, a study released Wednesday by the Environmental Working Group found.

The pollutants identified include common urban wastewater pollutants like caffeine and pharmaceuticals, an array of cancer-causing byproducts from municipal tap water chlorination,… read more

Study finds new nanomaterial could be breakthrough for implantable medical devices

November 11, 2008

Nanoporous ceramic membranes may create an interface between human tissues and medical devices that is free of protein buildup, leading to new dialysis devices and other revolutionary medical implants, a new study led by North Carolina State University has found.

Study finds value in ‘junk’ DNA

October 17, 2008

A University of Iowa study has found evidence that a significant number of exons (the building blocks for protein-coding genes) created from junk DNA seem to play a role in gene regulation.

Study Gives Key Role to Sleep in Helping Brain Learn Anew

January 29, 2008

During sleep, the synapses weaken, University of Wisconsin researchers have hypothesized.

This weakening performs a crucial role of sleep: restoring the brain for the next period of learning.

Study identifies new patterns of brain activation used in forming long-term memories

February 21, 2008

New York University and Weizmann Institute of Science researchers have identified patterns of brain activation linked to the formation of long-term memories in a simulated real-life experience, finding activity in new areas of the brain: the temporal pole, superior temporal gyrus, medial prefrontal cortex, and temporal parietal junction.

Previous studies had not simulated the real-world settings in which long-term memories are typically formed, and found only that medial temporal… read more

Study identifies small molecules mimicking key brain growth factor

April 20, 2010

Stanford University School of Medicine researchers have identified several small molecules that mimic BDNF, a key protein in the brain, a discovery that could open the door to new therapies for a variety of brain disorders.

BDNF belongs to a family of proteins called nerve growth factors, which are critical during development of the nervous system. When a growth factor binds to its receptor on the surface of a… read more

Study identifies ‘traffic engineer’ in neurons

A new University of Georgia study published in the journal Nature has identified a critical enzyme that keeps traffic flowing in the right direction in the nervous system, and the finding could eventually lead to new treatments for conditions such as Alzheimer’s and Parkinson’s disease.

Cells contain a network of tubes known as microtubules that are made of protein and serve as tracks for the shuttling… read more

Study Is Setback for Some RNA-Based Drugs

April 8, 2008

University of Kentucky researchers have found that RNA-interference-activating drugs now being tested in clinical trials do not work by silencing genes but by activating the immune system.

That could mean these drugs are not really precise tools and could have unexpected side effects.

The drugs aim to inactivate a gene contributing to leaky blood vessels in the back of the eye, the hallmark of the severe form of… read more
