It's not easy being a bacterium and constantly having to adapt to whatever your environment throws at you. Bacteria rely on their "memories" to fine-tune their ability to sense food and danger.

People with severe stomach disorders can sometimes suffer from chronic vomiting. This symptom can be treated with electrical impulses from a pacemaker in the stomach. A new method enables patients who could benefit from this treatment to be identified, and electrical stimulation leads to reduced nausea and fewer days in hospital, shows a study from Sweden.

An estrogenic drug that influences neurotransmitter and neuronal systems in the brain is showing promise as an effective therapy for women who suffer from schizophrenia.

Since the discovery of gene sequencing in the late 1970s, it was predicted that genetics would revolutionize medicine and provide answers to the causes of many of our common killers. But has genetic research delivered its promise?

Scientists made a huge step toward making the blind see, and they did it by using a form of gene therapy that does not involve the use of modified viruses. Scientists used a non-viral, synthetic nanoparticle carrier to improve and save the sight of mice with retinitis pigmentosa.

Researchers in Austria have successfully realized a single-atom laser, which shows the properties of a classical laser as well as quantum mechanical properties of the atom-photon interaction.

Interest in electric vehicles (EVs) and plug-in hybrids has come on strong over the past year or so, pushed relentlessly by carmakers promoting a newer, greener generation of transportation. As the Chevy Volt , Ford Transit Connect Electric , Nissan Leaf and others trickle out into the marketplace over the next year, it's clear that they will go only as far as their lithium ion batteries can take them (which right now isn't all that far).

The first sequenced drafts of the human genome were announced 10 years ago this June. President Bill Clinton remarked at the time that, "genome science will have a real impact on all of our lives." Although hopes were high, neither he nor the researchers involved promised magical genomic cures or personalized genomes for everyone by 2010. So when exactly can we, as individuals, expect to see that impact? [More]
