It might seem crazy for landlords to tell potential tenants about past bedbug infestations, but Alison Hill believes it will pay off in the long run. In a study, Hill found that while landlords would see a modest drop in rental income in the short term, they would make that money back in a handful of years, and the policies could dramatically slow the spread of the insects.

Working with a team of international researchers, Harvard scientists gathered survey data in several locations around the globe and found that, following the trauma of seeing a friend or loved one killed or injured during conflict, many became more religious.

A new Harvard study suggests that although the congenitally blind experience abstract visual phenomena such as rainbows and color differently, they still share with the sighted a common understanding of them.

Harvard researchers are using a chemical process known as triplet fusion upconversion to transform near-infrared photons into high-energy photons. The high-energy photons could be used in a huge range of applications, including a new type of precisely targeted chemotherapy, in which low-energy infrared lasers that penetrate deep into the body could be used to transform innocuous compounds into cancer-fighting drugs.

A new study shows that African grey parrots can perform some cognitive tasks at levels beyond those of 5-year-old humans. The results not only suggest that humans aren’t the only species capable of making complex inferences, but also point to flaws in a widely used test of animal intelligence.

Researchers have created the first cellular atlas of the primate retina and discovered that, while the fovea and peripheral retina share most of the same cell types, the cells are in different proportions, and show different gene expression patterns.

In a first-of-its-kind study, findings suggest that continued ocean warming and acidification could impact everything from how fish move to how they eat.
