50,000th molecule structure

The Protein Data Bank (PDB) based at Rutgers, The State University of New Jersey, and the University of California-San Diego (UCSD) this month reached a significant milestone.

Needle-size device

Engineers are creating a wireless device designed to be injected into tumours to tell doctors the precise dose of radiation received.

Real world problems

In 2002, transgenic food aid to African nations was rejected by the recipient governments. The EU's stand on agricultural biotechnology no doubt contributed to this decision.

Z ring's mysteries

Researchers have solved important puzzles concerning how certain proteins guide the reproduction of bacteria, discoveries that could lead to a new type of antibiotics.

Sadness and spending

How a person feels can impact routine economic transactions, whether he or she is aware of it or not.

Mobile terahertz devices

Researchers have mobilised the transmitting and receiving devices so that they can be used anywhere with ease.

Apple health benefits

Apple product consumers likely to have lower blood pressure, trimmer waistlines, and more nutrient dense diets.

Turning cells into fat

Researchers report the discovery of a critical early player, so-called 3T3-L1 cells, in the path that turns cells to fat.

Controlling genes

Researchers have discovered a gene in flies whose activity rises and falls depending upon the amount of protein and sugar in the insects' diets.

Pain and fatigue linked

A study reveals a biological link between pain and fatigue and may help explain why more women than men are diagnosed with chronic pain and fatigue conditions.

First cancer vaccine

Russian regulators have approved the world's first cancer vaccine, validating the introduction of a product even though it failed a late-stage clinical trial.

Manipulating immunity

One day it may be possible to mimic the tactics used by parasites to trick the body into accepting transplanted tissues or organs.

Looping genes

Researchers have discovered how a particular gene associated with breast cancer behaves, which may lead to better testing for the debilitating disease.

Soy benefits for teens

Evidence is growing from animal and human studies that genistein, a potent chemical found in soy, protects against development of breast cancer - but only if consumed during puberty.

Nano-stained glass

Carbon nanotubes are promising materials for many high-technology applications due to their exceptional mechanical, thermal, chemical, optical and electrical properties.

Negligent, attentive mice

Scientists describe a strain of mice that exhibit unusually high rates of maternal neglect, with approximately one out of every five females failing.

Fingerprint of Evolution

One of the steps in turning genetic information into proteins leaves genetic fingerprints, even on regions of the DNA that are not involved in coding for the final protein.

Atherosclerosis in adults

Aggressively lowering cholesterol and blood pressure levels below current targets may help to prevent - and possibly reverse - hardening of the arteries.

Manufactured Buckyballs

Even large amounts of manufactured nanoparticles, also known as Buckyballs, don't faze microscopic organisms that are charged with cleaning up the environment.

Creating quantum computers

A group of scientists recently demonstrated one of the basic building blocks for distributed quantum computing using entangled photons generated in optical fibers
