The description of compounds and interactions between atoms is one of the basic objectives of chemistry. Admittedly, chemical bonding models, which describe these properties very well, already exist. However, any deviation from the normal factors may lead to improving the models further. Chemists with Professor Thomas M. Klapötke at Ludwig-Maximilians-Universität (LMU) München have now analyzed a molecule, which has an extremely short bond length.

Increased social stress in childhood and young adulthood has a direct link to later increased dating violence, and that young social stress is impacted by things like unemployment and economic worries, according to Murray Straus, professor of sociology and co-director of the University of New Hampshire Family Research Laboratory.  The research, based on a 32-nation study,  was presented at the conference on “War, Terrorism, and Social Stress: Impacts on Crime and the Criminal Justice System” at the Institute of Criminology, The Hebrew University, Jerusalem, Monday, May 4, 2009.

He studied 14,252 university students from 68 universities in 32 nations in an International Dating Violence Study.

'Drought-proofing' Australia's urban regions by installing large domestic water tanks may enable the dengue mosquito Aedes aegypti to regain its foothold across the country and expand its range of possible infections, according to a new study published in PLoS Neglected Tropical Diseases. 

Dr Nigel Beebe and colleagues from the University of Queensland, CSIRO Entomology, the Australian Army Malaria Institute, and the Communicable Diseases Branch of Queensland Health, Brisbane, challenge the common assumption that climate change will drive the spread of this mosquito. 

An international team of scientists has determined the structure of the chlorophyll molecules in green bacteria that are responsible for harvesting light energy. The team's results one day could be used to build artificial photosynthetic systems, such as those that convert solar energy to electrical energy.

Self-cleaning walls, counter tops, fabrics, even micro-robots that can walk on water -- all those things and more could be closer to reality because of research recently completed by scientists at the University of Nebraska-Lincoln and at Japan's RIKEN institute. 

Humans have marveled for millennia at how water beads up and rolls off flowers, caterpillars and some insects, and how insects like water striders are able to walk effortlessly on water. It's a property called super hydrophobia and it's been examined seriously by scientists since at least the 1930s. 

Infants who receive the pneumococcal conjugate vaccine (PCV) following the combination vaccine for diphtheria, polio, tetanus, pertussis and Haemophilus influenzae type b (DPTaP-Hib vaccine) appear to experience less pain than those who are immunized in the opposite order, according to a report in the May issue of Archives of Pediatrics&Adolescent Medicine, a theme issue on vaccines. 

Injections are the most painful common medical procedure conducted in childhood, according to background information in the article.
