A new study has revealed that the locations and timing of tiger shark movement in the western North Atlantic Ocean have changed from rising ocean temperatures. These climate-driven changes have subsequently shifted tiger shark movements outside of protected areas, rendering the sharks more vulnerable to commercial fishing.
The ‘Platypus’ of the crab world was an active predator that lurked the Cretaceous seas
Researchers describe the unusually large optical features of Callichimaera perplexa, a 95-million-year-old crab fossil discovered in Colombia. The findings suggest Callichimaera perplexa was a highly visual, swimming predator.
BPA exposure of the placenta could affect fetal brain development
Scientists demonstrate the direct transmission of bisphenol A (BPA) from a mother to her developing child via the placenta could negatively impact fetal brain development.
Under a moon spell: Shark attacks related to lunar phases
New research suggests that more shark attacks occur during fuller phases of the moon. While the exact cause remains unclear, the researchers found that more shark attacks than average occur during periods of higher lunar illumination and fewer attacks than average occur during periods of lower illumination. Many different types...
Face masks cut distance airborne pathogens could travel in half, new study finds
The effectiveness of face masks has been a hotly debated topic since the emergence of COVID-19. However, a new study offers more evidence that they work. Researchers found that face masks reduce the distance airborne pathogens could travel, when speaking or coughing, by more than half compared to not wearing...
Study challenges evolutionary theory that DNA mutations are random
Researchers have found that DNA mutations are not random. This changes our understanding of evolution and could one day help researchers breed better crops or even help humans fight cancer.
Rainy days harm the economy
Economic growth goes down when the number of wet days and days with extreme rainfall go up, a team of scientists finds. Rich countries are most severely affected and herein the manufacturing and service sectors, according to their study. The data analysis of more than 1.500 regions over the past...
Earliest human remains in eastern Africa dated to more than 230,000 years ago
The age of the oldest fossils in eastern Africa widely recognized as representing our species, Homo sapiens, has long been uncertain. Now, dating of a massive volcanic eruption in Ethiopia reveals they are much older than previously thought.
Researchers determine nutritional properties of protein in cricket, locust and silkworm pupae insect powders
Animal farming has traditionally fulfilled human nutritional requirements for protein, but insects may serve as an alternative for direct human consumption in the future. Researchers are working to lay a foundation to develop efficient protein isolation techniques by determining the nutritional and functional properties of protein for cricket, locust and...
Common household cleaner can boost effort to harvest fusion energy on Earth
Path-setting findings demonstrate for the first time a novel regime for confining heat in stellarators. The demonstration could advance the twisty design as a blueprint for future fusion power plants.
