Circadian clock and remembering

The circadian rhythm that quietly pulses inside us all, guiding our daily cycle from sleep to wakefulness and back to sleep again, may be doing much more than just that simple metronomic task. It may aid learning.

New virus could combat malaria

A team of researchers, led by Dr. Jason Rasgon, have identified a previously unknown virus that is infectious to Anopheles gambiae. Scientist Live spoke with him about the discovery.

Astrocytes and synaptic plasticity

By mopping up excess neurotrophic factor from neuronal synapses, astrocytes may finely tune synaptic transmission to affect processes such as learning and memory.

Body's anti-HIV drug explained

A recent study reveals that humans have a built-in weapon against HIV and discloses a long-sought atomic structure of key enzyme and suggests new approach for drug development.

Pectin power

Scientists have found a new possible explanation for why people who eat more fruit and vegetables may gain protection against the spread of cancers.

Nanotechnology boosts war on superbugs

Scientists are using a novel nanomechanical approach to investigate the workings of vancomycin, one of the few antibiotics that can be used to combat increasingly resistant infections such as MRSA.

Important new hair-loss gene discovered

Researchers investigated over 500,000 positions in the human genome, and found a gene variant which occurs clearly more frequently in bald men than in control persons.

Tube selector reduces contamination

For laboratories looking to reduce sample contamination the new Micronic Tube Selector enables 'hands-free' manual picking and placing of sample tubes from any storage rack.

Nature influences nano-designs

Scientists are using designs in nature from extreme environments to overcome the challenges of producing materials on the nanometre scale.

Limits to plant-eating predators benefits

Plans to introduce plant-eating predators to fight the Japanese Knotweek that is spreading throughout Britain should not be seen as a magic bullet.

Saving sheep from lameness

A simple cheap individual approach to the care of sheep could slash the incidence of lameness in sheep saving 1.3 million sheep from lameness in the UK alone

Alzheimer's and low blood pressure

New study proposes that some people suffering from Alzheimer's disease experience a reduction in their high blood pressure because of cognitive decline.

Modelling 3D structure of amorphous materials

Researchers have accurately identified tools that model the atomic and void structures of a network-forming elemental material.

Turning to nature for new drugs

One of the best places to seek novel compounds for pharmaceutical drugs is within natural systems that have evolved over millions of years. Dr.K.C. Nicolaou spoke with Scientist Live recently about searching for potential drugs within nature.

Hearing loss apoptosis

Several genes that play a role in how our body's cells normally auto-destruct may play a role in age-related hearing loss, according to published research.

The Brain Imaging Centre

Recently, the University of Missouri Department of Psychological Sciences introduced an addition to their field of research with the opening of the Brain Imaging Centre.

Integrating antiretroviral therapy with TB treatment

A study shows that mortality among TB-HIV co-infected patients can be reduced by a remarkable 55 per cent, if antiretroviral therapy is provided with TB treatment at the same time.

Bacteria helps control weight

A single molecule in the intestinal wall, activated by the waste products from gut bacteria, plays a large role in controlling whether the host animals are lean or fatty.

Myelin decay contributes to physical decline

After middle age, we start to lose the battle to repair the myelin in our brain, and our motor and cognitive functions begin a long, slow downhill slide.

Shedding light on immune system suppression

A recent study described the suppression of immune responses in mice infected with lymphocytic choriomeningitis virus, pointing to potential new avenues for the development of drug treatments for immunosuppressive diseases in humans.
