| Astronomers find sun's 'long-lost brother,' pave way for family reunion Posted: 10 May 2014 12:17 PM PDT Astronomers have identified the first "sibling" of the Sun -- a star that was almost certainly born from the same cloud of gas and dust as our star. The newly developed methods for locating the Sun's 'siblings' will help other astronomers find other "solar siblings," work that could lead to an understanding of how and where our Sun formed, and how our solar system became hospitable for life.  |
| Link between insecticides and collapse of honey bee colonies strengthened Posted: 09 May 2014 08:07 AM PDT Two widely used neonicotinoids -- a class of insecticide -- appear to significantly harm honey bee colonies over the winter, particularly during colder winters, according to researchers. The study replicated a 2012 finding from the same research group that found a link between imidacloprid and Colony Collapse Disorder, in which bees abandon their hives over the winter and eventually die. The new study found low doses of a second neonicotinoid, clothianidin, had the same negative effect.  |
| Experiencing letters as colors: New insights into synesthesia Posted: 09 May 2014 04:41 AM PDT Scientists studying the bizarre phenomenon of synasthesia – best described as a "union of the senses" whereby two or more of the five senses that are normally experienced separately are involuntarily and automatically joined together – have made a new breakthrough in their attempts to understand the condition.  |
| 'Electrosmog' disrupts orientation in migratory birds, scientists show Posted: 08 May 2014 01:36 PM PDT For the first time, scientists have demonstrated that the magnetic compass of robins fails entirely when the birds are exposed to AM radio waveband electromagnetic interference -- even if the signals are just a thousandth of the limit value defined by the World Health Organization as harmless.  |
| 'Rice theory' explains north-south China cultural differences Posted: 08 May 2014 11:17 AM PDT A new cultural psychology study has found that psychological differences between the people of northern and southern China mirror the differences between community-oriented East Asia and the more individualistic Western world -- and the differences seem to have come about because southern China has grown rice for thousands of years, whereas the north has grown wheat.  |
| Clean before you clean: What's on your toothbrush just might surprise you Posted: 06 May 2014 06:44 AM PDT Do you know Staphylococci, coliforms, pseudomonads, yeasts, intestinal bacteria and -- yes -- even fecal germs may be on your toothbrush? Appropriate toothbrush storage and care are important to achieving personal oral hygiene and optimally effective plaque removal.
