UN sustainable energy initiative could put world on a path to climate targets
The UN's Sustainable Energy for All initiative, if successful, could make a significant contribution to the efforts to limit climate change to target levels, according to a new analysis from IIASA and ETH Zurich.

UC Santa Barbara scientists develop a whole new way of harvesting energy from the sun
A new method of harvesting the sun's energy is emerging, thanks to scientists at UC Santa Barbara's departments of chemistry, chemical engineering, and materials.

Researchers at IRB Barcelona discover a general mechanism that accelerates tumor development
ICREA professor Raúl Méndez publishes a study in Nature describing how the CPBE1 protein

MBL scientists find genes linked to human neurological disorders in sea lamprey genome
Scientists at the Marine Biological Laboratory have identified several genes linked to human neurological disorders, including Alzheimer's disease, Parkinson's disease and spinal cord injury, in the sea lamprey, a vertebrate fish whose whole-genome sequence is reported this week in the journal Nature Genetics.

Study: Babies born by C-section at risk of developing allergies
For expectant moms who may contemplate the pros and cons of natural child birth or Caesarian section, a Henry Ford Hospital study suggests that C-section babies are susceptible to developing allergies by age two.

Taking the gamble out of DNA sequencing
Scientists have developed an algorithm to predict how much can be learned in a large-scale DNA sequencing experiment -- with potential applications in every field of science

Distinct niches in bone marrow nurture blood stem cells
In research that could one day improve the success of stem cell transplants and chemotherapy, scientists have found that distinct niches exist in bone marrow to nurture different types of blood stem cells.

Scientists find surprising new influence on cancer genes
Small stretches of DNA in the human genome are known as

Laser mastery narrows down sources of superconductivity
Uncovering the mechanism behind high-temperature superconductivity -- a phenomenon with tremendous value to advances in energy efficiency and sustainability -- remains one of the greatest and most pressing puzzles in physics.

Analytical trick accelerates protein studies
Researchers at the University of Wisconsin-Madison have found a new way to accelerate a workhorse instrument that identifies proteins.

Graphene: A material that multiplies the power of light
Researchers at the Institute of Photonic Science, demonstrate that graphene is able to convert a single photon that it absorbs into multiple electrons that could drive electric current -- a very promising discovery that makes graphene an important alternative material for light detection and harvesting technologies, now based on conventional semiconductors like silicon.

New type of gene that regulates tumor suppressor PTEN identified
Researchers at Karolinska Institutet in Sweden have identified a new so-called pseudogene that regulates the tumor-suppressing PTEN gene.

Ability of brain to protect itself from damage revealed
The origin of an innate ability the brain has to protect itself from damage that occurs in stroke has been explained for the first time.

Fragments of continents hidden under lava in the Indian Ocean
A new micro-continent has been detected under Mauritius and Reunion.

Scientists find bone-marrow environment that helps produce infection-fighting T and B cells
The Children's Medical Center Research Institute at UT Southwestern has deepened the understanding of the environment within bone marrow that nurtures stem cells, this time identifying the biological setting for specialized blood-forming cells that produce the infection-fighting white blood cells known as T cells and B cells.

Asthma drug found highly effective in treating chronic, severe hives and itch
An international team of researchers has found that a once-a-month, high-dose injection of a commonly used asthma drug is highly effective in treating teens and adults chronically afflicted with hives and severe, itchy rash.

Preventing chronic pain with stress management
For chronic pain sufferers, such as people who develop back pain after a car accident, avoiding the harmful effects of stress may be key to managing their condition.

International Conference on Governance of Tobacco in the 21st Century
A gathering of public health leaders and experts from the World Health Organization, Harvard University, the European Union, the African Union, and more than two dozen nations to consider how to keep the plague of tobacco smoking, illness, and death from spreading from the Developed to the Developing world.

Pain from the brain
Psychogenic diseases, formerly known as

Quantum algorithm breakthrough
An international research group led by scientists from the University of Bristol, UK, and the University of Queensland, Australia, has demonstrated a quantum algorithm that performs a true calculation for the first time.
