Researchers used a newly developed imaging technique called serial block face scanning electron microscopy, to produce a digital reconstruction of eye tissues from the outer retina, at very high resolution. This is the first time this technology has been used to fully reconstruct cells from the retina and could provide new insights into the causes of irreversible blinding diseases.

Cells are effectively 'blindfolded' as they lose sensitivity to their surroundings early in cancer progression, but scientists used a new method to find some cancer cells are able to switch this sense back on in order to move and spread. In future, these cells could potentially be targeted by treatments before cancer spreads to give patients a better chance of recovery.

A new study is underscoring the importance of drivers keeping their eyes on the road -- even when they are in an automated vehicle (AV). The findings revealed that drivers can become over-reliant on AV technology. This was especially true with a type of in-vehicle display the team coined as takeover request and automation capability (TORAC).

Humans are exposed to various environmental or dietary molecules that can attenuate or even increase the effect of therapeutic drugs. Studies on the industrial chemical bisphenol A and the phytoestrogen genistein, for example, have shown drug-exposome interactions. However, interactions between exposures and therapeutic agents have not been systematically investigated to date, conclude chemists.

A cancer-killing virus that scientists developed could one day improve the immune system's ability to eradicate tumors in colon cancer patients, reports a new study. The preclinical research is a first step to showing that oncolytic virus CF33 can target hard-to-treat tumors that 'handcuff' the immune system and keep T cells from activating the immune system to kill cancer cells.
