Kalanchoe fedtschenkoi is unique because it captures most of its carbon dioxide at night when the air is cooler and more humid.



Combatting leukaemia

Researchers have shown that patients with chronic myelogenous leukaemia may be cured of the disease with an optimally timed cancer vaccine.



Same drug, different results

Medicine has moved a little bit closer to the era of tailor-made treatments, based on the unique genetic profiles of individual patients, according to recent research.



Bitter orange SRMs

Scientists have developed Standard Reference Materials (SRMs) for bitter orange, long used in folk medicine and now increasingly used in herbal weight-loss products.



Plan properly for autoclave positioning and installation

When planning and designing a laboratory the task of positioning or repositioning a Laboratory Autoclave can be at either end of the 'easy-impossible' scale. Tony Collins discusses the problems of autoclave positioning and installation.

Feed that cold!

Researchers studying deer mice have discovered evidence to support what mothers everywhere have long suspected: the immune system needs food to function properly.



Early-onset obesity

A history of early-onset paternal obesity increases the odds of elevated liver enzyme levels in offspring and points to a genetic link.



Smear campaign

There is a new tool in the arsenal to fight multidrug-resistant tuberculosis: a rapid diagnostic test that can function in high-burden settings such as public health clinics.



Better and faster

A diagnostic kit shows new promise for distinguishing between tuberculosis and its infections from disease caused by related mycobacteria family.
