New buffer resists pH change, even as temperature drops
Researchers at the University of Illinois have found a simple solution to a problem that has plagued scientists for decades: the tendency of chemical buffers used to maintain the pH of laboratory samples to lose their efficacy as the samples are cooled.

Cool Picture: Rainbows of Ink in Water
The image, entitled Four Dimensions, depicts the radial spread of ink in water. Ink flows out fast from static blobs such as those shown above right, taking up patterns across and within the water.

Cooking Can Preserve, Boost Nutrient Content Of Vegetables
In a finding that defies conventional culinary wisdom, researchers in Italy report that cooking vegetables can preserve or even boost their nutritional value in comparison to their raw counterparts, depending on the cooking method used.

Beer Brewed Long Ago by Native Americans
Ancient Pueblo Indians brewed their own brand of corn beer, a new study suggests, contradicting claims that the group remained dry until their first meeting with the Europeans.

Everyday Items, Complex Chemistry
Holiday shoppers may worry about whether the toys they buy contain lead, but some scientists are urging consumers to focus on the thousands of chemicals in everyday household items.

Water may hide harmful chemical cocktail
Next time you're washing your hair, spare a thought for your neighbours' health. A report by the UK's Royal Society of Chemistry (RSC) says chemicals from consumer products and drugs could be breaking down and recombining into a harmful brew in water supplies.

New chemistry and microsurfaces have led to super oil-repellent materials that are self-cleaning
Researchers have made materials that repel oil and are able to clean themselves without the help of soap and water. What's more, the researchers describe exactly how the materials work, which could help others design similar materials. This could lead to a range of applications, including fingerprint-shedding cell-phone displays.

Model predicts structure of crystals
One of the continuing scandals in the physical sciences is that it remains impossible to predict the structure of even the simplest crystalline solids from their chemical composition.” So wrote the chemist and former Nature editor John Maddox in 1988 (see Nature 335, 201), who was bemoaning the lack of a computational method to predict how molecules will arrange themselves in the solid state.

Where have I seen that before?
There was something strangely familiar about results published in two high-profile chemistry journals recently: as one researcher has since pointed out, they accidentally replicated an experiment that was done more than a century ago.
