MALDI LTQ XL mass spectrometer

The addition of MALDI to the LTQ XL linear ion trap provides information-rich spectra that are essential for the analysis of digested proteins and PTMs.

Cellular transport insight

Scientists have now discovered how molecular motors transport cargoes in cells. Two competing teams of motors pull in opposite directions, like in a tug-of-war contest.

Cortisol in fibromyalgia fight

Chronic fatigue syndrome and fibromyalgia are two serious and debilitating diseases with no confirmed cause and limited treatment options.

Norwalk virus' weakness

An international team has determined the detailed structure of the enzyme the Norwalk virus uses to make copies of its genetic code in order to replicate itself.

Loopy photons

Researchers have developed a new method for creating pairs of entangled photons and used them to test fundamental concepts in quantum theory.

Conventional to molecular

Researchers have set the stage for building the evolutionary link between the microelectronics of today and future generations of organic devices.

Advantages of metafilms

Thin films made of meta-materials - man-made composites engineered to offer strange combinations of electromagnetic properties - can reduce microwaves.

Scans spot hidden tumours

Full-body PET/CT scanning can detect unsuspected, treatable tumours in 3 of 15 patients with Li-Fraumeni syndrome, a rare genetic cancer disease.

Watching bleomycin

Researchers have created the first three-dimensional image of how a well-established chemotherapy agent targets and binds to DNA.

Microbial evolution

A mathematical approach for analysing a protein simultaneously in a set of ecologically distinct species to identify occurrences of natural selection has been developed.

Multiple sclerosis symptoms

A bodysuit that heats or cools a patient, combined with painless measurements of eye movements, helps to study the link between body temperature and MS symptoms.

Fighting cervical cancer

The virus responsible for most cases of cervical cancer has a serious weakness which may provide hope for new treatments for the disease.

Buckyballs squeeze hydrogen

Material scientists have discovered that buckyballs are so strong they can hold volumes of hydrogen nearly as dense as those at the centre of Jupiter.

Brain imaging study

Researchers have conducted the first-ever brain imaging study that directly contrasts two different techniques for emotion regulation.

Designer enzyme protection

Designer enzymes will have applications for defence against biological warfare, by deactivating pathogenic biological agents.

Assessing public health preparedness

Since 2001, state and local health departments in the United States (US) have accelerated efforts to prepare for high-impact public health emergencies.

Genotyping of Bacillus anthracis and Yersinia pestis

Anthrax and plague bacteria are etiological agents for worldwide zoonotic diseases and are considered among the most feared potential bioterror agents.

Virus detection and identification

PCR-based detection and identification of viruses assumes a known, relatively stable genome.

What women want

A new study from The University of Texas at Austin reveals women's preferences can be influenced by their own attractiveness.

Lung cancer prevention

A small RNA molecule, known as let-7 microRNA (miRNA), substantially reduced cancer growth in multiple mouse models of lung cancer.
