COLUMBIA, Mo. - In 2012, Americans sent more than 14 million tons of textile waste to trash dumps around the country, despite many options for consumers to repurpose or recycle textile waste, including donating old clothes to charities and recycling the materials to be remade into other products. Pamela Norum, professor and interim department chair of textile and apparel management at the University of Missouri, found that younger adults from ages 18-34 are much less likely to throw old clothes and other textile waste into the garbage than older adults. She also found that millennials were more likely to donate clothing to secondhand stores such as Goodwill and the Salvation Army.

Anthocyanins, pigments that give plants their red, blue, or purple hues, are not typically produced in citrus fruits grown under tropical or subtropical conditions.

Now, scientists have genetically engineered a lime that contains anthocyanins, which they say has several potential benefits. Manjul Dutt, Daniel Stanton, and Jude Grosser, from the Citrus Research and Education Center at the University of Florida, say that the discovery will allow the cultivation of new citrus fruits in the major subtropical citrus belt and/or the production of ornamental plants, depending on the cultivar.

The process also creates opportunities for novel fruit, leaf, and flower colors to be produced by regulating anthocyanin biosynthesis.

Varnish does more than just provide a protective sheen to a violin. It influences the vibrations and impulses that the wood absorbs and therefore the quality of sound the instrument produces, says Marjan Gilani of the Swiss Federal Laboratories for Material Science and Technology (EMPA) in Switzerland. In research published in Springer's journal Applied Physics A, Gilani and her colleagues demonstrate the importance of the vibro-mechanical properties of varnish, its chemical composition, thickness and penetration into wood.

Human communication is powered by rules for combining words to generate novel meanings. Such syntactical rules have long been assumed to be unique humans. A new study, published in Nature Communications, show that Japanese great tits combine their calls using specific rules to communicate important compound messages. These results demonstrate that syntax is not unique to humans. Instead, syntax may be a general adaptation to social and behavioural complexity in communication systems.

We do not merely recognize objects - our brain is so good at this task that we can automatically supply the concept of a cup when shown a photo of a curved handle or identify a face from just an ear or nose. Neurobiologists, computer scientists, and robotics engineers are all interested in understanding how such recognition works - in both human and computer vision systems. New research by scientists at the Weizmann Institute of Science and the Massachusetts Institute of Technology (MIT) suggests that there is an "atomic" unit of recognition - a minimum amount of information an image must contain for recognition to occur.

Dead European honeybees have almost 57 different pesticides detected, according to a new paper in the Journal of Chromatography A.

Should that be a concern? Not really. The great thing about modern technology is that we can detect parts per trillion, orders of magnitude what can be harmful. Yet proponents of low-dose effect, like environmental groups and researchers enabling them, will want to claim that being able to detect something means it must be bad.
