Nano-messenger opens way for new cancer treatment

in technology, environment, medicine

A new study from Karolinska Institutet shows that exosomes, nanoparticles that transmit information between cells, constitute a potential new treatment strategy for several cancers. The study, which was conducted on mice, was published recently online in the scientific journal Cancer Research.

Imperfect Graphene Makes Better Chemical Sensors

in technology, environment

A new study shows that chemical sensors made with less perfect graphene may have better sensitivity. Researchers produced graphene chemical sensors with either near-perfect structures or deliberatively defective structures and found that the graphene sensors with edges and line defects were more sensitive in detecting gas analytes.

in environment, medicine, biology

Can maternal diet influence offspring sex ratio?  According to a research report from New South Wales (Australia) Department of Primary Industries, ratio of omega-6 to omega-3 fatty acids in the diet of mother has a profound effect on offspring sex ratio. 

Prenatal stress passed across generations and disrupt masculinization of the developing mouse brain

in environment, medicine, biology, omics

A new study finds that experiences in the womb can lead to individual differences in stress response that may be passed across generations.  The study shows that sons of male mice exposed to prenatal stress are more sensitive to stress as adults and these mice may have smaller testes.

The study was published in the August 17 issue of The Journal of Neuroscience.

High Levels of Flame Retardant Chemicals in California Pregnant Women

in environment, medicine

Pregnant women in California have very high levels of banned chemicals used in flame retardants, the highest levels ever reported among pregnant women worldwide!  This is the result of a study published by scientists at the University of California San Francisco and they further add that this is likely due to California’s strict flammability regulations.
