  • Pointy eggs more likely to stay put in birds’ cliffside nests, study finds

    Natural selection – that merciless weeder-outer of biological designs that are out of step with the times – also is a wily shaper of traits. Exhibit A is the pointy murre egg, according to new research published in the Journal of Experimental Biology.

  • New CRISPR technique skips over portions of genes that can cause disease

    In a new study in cells, University of Illinois researchers have adapted CRISPR gene-editing technology to cause the cell’s internal machinery to skip over a small portion of a gene when transcribing it into a template for protein building. This gives researchers a way not only to eliminate a mutated gene sequence, but to influence how the gene is expressed and regulated.

    Such targeted editing could one day be useful for treating genetic diseases caused by mutations in the genome, such as Duchenne’s muscular dystrophy, Huntington’s disease or some cancers.

  • Genomic study ties insect evolution to the ability to detect airborne odors

    A new study reveals that all insects use specialized odorant receptors that enable them to detect and pursue mates, identify enemies, find food and – unfortunately for humans – spread disease. This puts to rest a recent hypothesis that only some insects evolved the ability to detect airborne odors as an adaptation to flight, the researchers said.

  • Nowhere to hide: Molecular probe illuminates elusive cancer stem cells in live mice

    After a primary tumor is treated, cancer stem cells may still lurk in the body, ready to metastasize and cause a recurrence of the cancer in a form that’s more aggressive and resistant to treatment. University of Illinois researchers have developed a molecular probe that seeks out these elusive cells and lights them up so they can be identified, tracked and studied not only in cell cultures, but in their native environment: the body.

    In a paper published in the journal ACS Central Science, the researchers described the probe’s effectiveness in identifying cancer stem cells in cultures of multiple human cancer cell lines as well as in live mice.

  • Study: In darters, male competition drives evolution of flashy fins, bodies

    Scientists once thought that female mate choice alone accounted for the eye-catching color patterns seen in some male fish. But for orangethroat darters, male-to-male competition is the real force behind the flash, a new study finds.

  • Chemicals that keep drinking water flowing may also cause fouling

    Many city drinking water systems add softening agents to keep plumbing free of pipe-clogging mineral buildup. According to new research, these additives may amplify the risk of pathogen release into drinking water by weakening the grip that bacteria – like those responsible for Legionnaires’ disease – have on pipe interiors.  

  • Study explores risk factors linked to chikungunya and dengue outbreaks

    In one of the largest studies of its kind, researchers analyzed chikungunya and dengue outbreak data from 76 countries over a period of 50 years, focusing on regions across the Indian Ocean that are hard hit by these and other mosquito-borne infectious diseases.

  • In rats, perinatal exposure to phthalates impairs brain structure and function

    Male and female rats exposed in the womb and during lactation to plasticizing chemicals known as phthalates had significantly fewer neurons and synapses than those that were not exposed, researchers report in a new study. The phthalate-exposed rats had reductions in the size of their medial prefrontal cortex, a brain region that regulates behavior, and showed deficits in cognitive flexibility.
