'Mind's Eye' Influences Visual Perception
Letting your imagination run away with you may actually influence how you see the world. New research has found that mental imagery -- what we see with the "mind's eye" -- directly impacts our visual perception.

Circulating Tumor Cells Can Reveal Genetic Signature Of Dangerous Lung Cancers
A microchip-based device that detects and analyzes tumor cells in the bloodstream can be used to determine the genetic signature of lung tumors, allowing identification of those appropriate for targeted treatment and monitoring genetic changes that occur during therapy.

Following Traumatic Brain Injury, Balanced Nutrition Saves Lives
Clinician-scientists are suggesting an immediate and important change to guidelines used in the care of patients with traumatic brain injury. The researchers say that following traumatic brain injury, patients should be given nutritional supplementation through a gastric feeding tube as soon as possible, which they say can improve their chances of survival by as much as four-fold.

Some Fundamental Interactions Of Matter Found To Be Fundamentally Different Than Thought
When an atom collides with a molecule, traditional wisdom said the atom had to strike one end of the molecule hard to deliver energy to it. People thought a glancing blow from an atom would be useless in terms of energy transfer, but that turns out not to be the case. "We have a new understanding of how energy can be transferred in collisions at the molecular scale," said Richard Zare, of Stanford University.

Invasive Treatment Appears Beneficial For Men And High-risk Women With Certain Coronary Syndromes
An analysis of previous studies indicates that among men and high-risk women with a certain type of heart attack or angina an invasive treatment strategy (such as cardiac catheterization) is associated with reduced risk of rehospitalization, heart attack or death, whereas low-risk women may have an increased risk of heart attack or death with this treatment.

In Vitro Fertilization: New Method Predicts Which Women WIll Get Pregnant
Researchers at the Stanford University School of Medicine have identified a method that can predict with 70 percent accuracy whether a woman undergoing in vitro fertilization treatment will become pregnant. The researchers found that four factors - total number of embryos, number of eight-cell embryos, percentage of embryos that stopped dividing and would die, and the woman's follicle-stimulating hormone level, a measurement that estimates ovarian function - were most important in determining a woman's chance of becoming pregnant. The four together were 70 percent accurate in predicting whether the current IVF cycle would result in a pregnancy.

Death, Division Or Cancer? Newly Discovered Checkpoint Process Holds The Line In Cell Division
Each day, a staggering number of cells perform a feat that still amazes researchers with its complexity: they divide to produce perfect replicas of each other. The process is called mitosis, and an inability to control it is one of the hallmarks of cancer. Researchers have discovered a novel biochemical activity involved in controlling cell division, which they've called the mitotic checkpoint factor 2. While the proteins involved in MCF2 remain to be determined, their findings offer insight into a fundamental question of biology, which may also help to increase the efficiency of cancer drugs like gemcitabine or paclitaxel.

Newborns In ICUs Often Undergo Painful Procedures, Most Without Pain Medication
An examination of newborn intensive care finds that newborns undergo numerous procedures that are associated with pain and stress, and that many of these procedures are performed without medication or therapy to relieve pain.

Researchers Are First To Simulate The Binding Of Molecules To A Protein
You may not know what it is, but you burn more than your body weight of it every day. Adenosine triphosphate, a tiny molecule that packs a powerful punch, is the primary energy source for most of your cellular functions. Now researchers have identified a key step in the cellular recycling of ATP that allows your body to produce enough of it to survive.

Asteroid Impacts On Earth: A Protection Plan
A century ago this week, an event in far-off Siberia rang a cosmic wake-up call for Earth. That explosive event over remote Tunguska is generally viewed by scientists as a large space rock that pierced through the atmosphere of Siberia, then detonated to flatten some 2,000 square kilometers of trees.
