Scientists find 'bully' genes in common childhood tumor
In a genome sequencing study of 74 neuroblastoma tumors in children, scientists at the Johns Hopkins Kimmel Cancer Center and the Children's Hospital of Philadelphia found that patients with changes in two genes, ARID1A and ARID1B, survive only a quarter as long as patients without the changes.

Origin of intelligence and mental illness linked to ancient genetic accident
Scientists have discovered for the first time how humans -- and other mammals -- have evolved to have intelligence.

Gap between present emissions and the 2-degree target
Carbon dioxide emission reductions required to limit global warming to two degrees Celsius are becoming a receding goal based on new figures reported today in the latest Global Carbon Project calculations published today in the advanced online edition of Nature Climate Change.

Scientists at Scripps Research Institute discover how 2 proteins help keep cells healthy
Scientists at The Scripps Research Institute have determined how two proteins help create organelles, or specialized subunits within a cell, that play a vital role in maintaining cell health.

Bismuth provides perfect dance partners for quantum computing qubits
New research has demonstrated a way to make bismuth electrons and nuclei work together as qubits in a quantum computer.

Surprising results from study of non-epileptic seizures
A Loyola University Medical Center neurologist is reporting surprising results of a study of patients who experience both epileptic and non-epileptic seizures.

Shifting the safety balance for overnight workers
An international team of sleep researchers has developed the world's first screening tool to help reduce workplace accidents and illnesses, including cardiovascular disease and cancer, caused by shift work.

Cell surface transporters exploited for cancer drug delivery
According to Whitehead Institute researchers, a protein known as monocarboxylate transporter 1 (MCT1), which is highly expressed in a subset of metabolically altered cancer cells, is needed for the entry of the investigational cancer drug 3-bromopyruvate (3-BrPA) into malignant cells.

Brain and nervous system damaged by low-level exposure to organophosphate pesticides
Scientists have found that low-level exposure to organophosphates produces lasting decrements in neurological and cognitive function.

Genes linked to low birth weight, adult shortness and later diabetes risk
An international team of genetics researchers has discovered four new gene regions that contribute to low birth weight.

New gene-sequencing tools offer clues to highest-risk form of a childhood cancer
Using powerful gene-analysis tools, researchers have discovered mutations in two related genes, ARID1A and ARID1B, that are involved in the most aggressive form of the childhood cancer neuroblastoma.

Record high for global carbon emissions
Global CO2 emissions are set to rise again in 2012, reaching a record high of 35.6 billion tons -- according to the University of East Anglia.

International study points to inflammation as a cause of plaque buildup in heart vessels
Fifteen new genetic regions associated with coronary artery disease have been identified by a large, international consortium of scientists -- including researchers at the Stanford University School of Medicine -- taking a significant step forward in understanding the root causes of this deadly disease.

Glowing fish shed light on metabolism
A tiny, translucent zebrafish that glows green when its liver makes glucose has helped an international team of researchers identify a compound that regulates whole-body metabolism and appears to protect obese mice from signs of metabolic disorders.

A better way to make chemicals?
For the first time, scientists have studied a mechanochemical milling reaction in real time, using highly penetrating X-rays to observe the surprisingly rapid transformations as the mill mixed, ground, and transformed simple ingredients into a complex product.

A shock to pollution in chemistry
Solvents are everywhere in chemistry and a major environmental concern.

Childhood trauma leaves mark on DNA of some victims
Gene-environment interaction causes lifelong dysregulation of stress hormones.

The University of Ottawa Heart Institute participated in the largest genetic study of Coronary Artery Disease to date.

Stanford researchers discover master regulator of skin development
The surface of your skin, called the epidermis, is a complex mixture of many different cell types -- each with a very specific job.

Insights into the genetic causes of coronary artery disease and heart attacks
By identifying a further 15 genetic regions and 104 independent genetic variants associated with coronary artery disease, one of the most common causes of death in the worldwith, researchers have identified some of the most prominent biological pathways that underlie the disease.
