Happiness differs for men and women

Less able to achieve their life goals, women end up unhappier than men later in life - even though they start out happier, reveals new research.

Surface-enhanced Raman scattering

Detecting deadly fumes in subways, toxic gases in chemical spills, and hidden explosives in baggage is becoming easier and more efficient with a measurement technique called surface-enhanced Raman scattering.

Crawling the Web: Pain pathways

Everyday, Scientist Live turns its eyes to the Web around it and highlights news and research across the Internet. Today we turn to pain pathways and HIV entry inhibitors.

Communications within a cell

Scientists have discovered how the calcium sensor protein calmodulin can gauge the local flow of calcium and global calcium flow entering the many channels across the entire cell.

Alzheimer's drug trial moves forward

The clinical trial of GAMMAGARD Intravenous Immunoglobulin has produced results that show significantly better global outcomes, cognitive performance and daily functioning in patients.

Self-repairing cartilage

A strain of mice with the natural ability to repair damaged cartilage may one day lead to significant improvements in treatment of human knee, shoulder and hip injuries.

Drug prevents alcoholism relapse

Scientist identifies brain receptor that triggers euphoric feelings from alcohol as well as a drug that blocks the heightened pleasure relapsing alcoholics experience.

Behind cocaine addiction

Laboratory rats that voluntarily use cocaine demonstrated a persistent cellular memory in the brain's reward centre, even in the absence of the drug.

Genetic factors in schizophrenia

Studies show that a combination of environmental and genetic factors form a complex interplay that leads to the onset of schizophrenia.

Building a healthier plant

Scientists have found a gene essential to photosynthesis and for iron metabolism, both of which are necessary for producing a healthy plant and nutritious food source.

Increasing crop efficiency

Scientists are genetically modifying plant root systems to improve their ability to find the water essential to their survival as a means of compensating for inefficient irrigation methods.

The future of Kiwi fruit

Scientists have unlocked the genetic secrets behind the colour, flavour, shape, nutrition, and ripening of Kiwis, helping breeders grow new varieties.

DNA change during depression and suicide

Autopsies usually point to a cause of death but now a study of brain tissue collected during these procedures, may explain an underlying cause of major depression and suicide.

Alcohol tolerance influenced by miRNA

A new study now indicates that microRNA may influence the development of alcohol tolerance, a hallmark of alcohol abuse and dependence.

HIV therapy benefits drug users

Contrary to common belief, recent research has shown little difference in the survival rate between HIV positive injection drug users and non-injection users.

Revised HIV treatment guidelines

An evaluation of recent data has led to an update in the guidelines and recommendations for anti-retroviral treatment of adult HIV infection.

HIV drugs hamper TB therapy

Patients receiving rifampicin-based anti-tuberculosis therapy are more likely to experience virological failure when starting nevirapine-based anti-retroviral therapy.

Superfluid-superconductor findings

Scientists have documented the way a superfluid influences the behaviour of a superconductor, advancing their understanding of the motion of neutron stars.

Gene found to protect liver

Researchers have discovered that a protein called FOXA2 controls the maintenance of proper levels of bile in the liver.

Golden nanostructures

Physicists recently discovered that in a charged state, atoms arrange themselves differently than when they are uncharged.
