For decades, fish-eating killer whales in the Pacific Northwest have been observed harassing and even killing porpoises without consuming them —- a perplexing behavior that has long intrigued scientists.
Photo credit: Frontiers We take a moment to reflect on the information, resources, and actions taken over the past several months towards promoting longer, more prosperous lives on a healthier planet. Photo credit: Frontiers Women in Science Our Women in Science blog continues to showcase the diverse stories and achievements of women researchers from various fields.
By Mischa Dijkstra, Frontiers science writer Veterinarian researchers performed a blinded randomized controlled trial to show that a commercially available water additive with pomegranate extract is effective in limiting the reformation of plaque and tartar on the teeth of dogs after a professional dental cleaning. This could help to prevent periodontal disease in the long term.
A new study may provide key answers to how to help people experiencing chronic back pain. The study examined the critical connection between the brain and pain for treating chronic pain. Specifically, they looked at the importance of pain attributions, which are people's beliefs about the underlying causes of their pain, to reduce chronic back pain severity.
A new study has documented the abilities of individual wild Asian elephants to access food by solving puzzles that unlocked storage boxes. It is the first research study to show that individual wild elephants have different willingness and abilities to problem solve in order to get food.
In lonely people, the boundary between real friends and favorite fictional characters gets blurred in the part of the brain that is active when thinking about others, a new study found.

In lonely people, the boundary between real friends and favorite fictional characters gets blurred in the part of the brain that is active when thinking about others, a new study found.
Scientists have demonstrated 'multielement ink' -- the first 'high-entropy' semiconductor that can be processed at low-temperature or room temperature. The new material could enable cost-effective and energy-efficient semiconductor manufacturing.
Researchers tried a new approach to resolve the scientific debate over whether it was a giant asteroid or volcanoes that wiped out the dinosaurs -- they removed scientists from the debate and let the computers decide. The researchers created a model powered by 130 interconnected processors that, without human input, reverse-engineered the Cretaceous-Paleogene mass extinction until they reached a scenario that matched the fossil record.
Chemical engineers have designed a fuel that ignites only with the application of electric current. Since it doesn't react to flames and cannot start accidental fires during storage or transport, it is a 'safe' liquid fuel.
A team of scientists has discovered and analyzed the first direct evidence of basketry among hunter-gatherer societies and early farmers in southern Europe in the Cueva de los Murciélagos of Albuñol (Granada, Spain). This site is one of the most emblematic archaeological sites of prehistoric times in the Iberian Peninsula due to the unique preservation of organic materials found there.
Humanity continuously emits greenhouse gases and thereby worsens global warming. Increasing research efforts go into developing strategies to convert these gases, such as carbon dioxide (CO2), into valuable products. CO2 accumulates dramatically over the years and is chemically very stable, thus challenging to transform. Yet, for billions of years, some microbes have actively captured CO2 using highly efficient enzymes.
Short-term exposure to air pollution may be linked to an increased risk of stroke. Short-term exposure was defined as occurring within five days of the stroke.
Data from wearables show that deviations from normal sleep and activity in pregnancy are connected to a risk for premature delivery, a new study found.
