Sound Reveals Giant Blue Whales Are Dancing With The Wind To Find Food

Leave a Comment / Science / By

A study by MBARI researchers and their collaborators published today in Ecology Letters sheds new light on the movements of mysterious endangered blue whales. The research team used a directional hydrophone on MBARI’s underwater observatory, integrated with other state-of-the-art technology, to listen to blue whales’ booming vocalizations. They used these sounds to track the movements …

New path to evolution: how the DNA of our mitochondria finds its way into our genomes

Leave a Comment / Science / By

In a study published today in Nature, researchers from the University of Cambridge and Queen Mary University of London show that mitochondrial DNA also appears in some cancerous DNA, suggesting that it acts as an adhesive bandage for attempt to repair the damage done to our genetic code. Mitochondria are tiny “organelles” found in our …

Astronomers discover pair of ‘cataclysmic’ stars with shortest orbit yet

Leave a Comment / Science / By

Almost half of the stars in our galaxy are solitary like the sun. The other half includes stars that surround other stars, in pairs and multiples, with orbits so tight that some star systems could fit between Earth and the Moon. Astronomers at MIT and elsewhere have discovered a stellar binary, or pair of stars, …

Laser scanning technology enables safe and efficient tunnel construction monitoring and measurement

Leave a Comment / Science / By

In a study published in Minerals, a deformation measurement and monitoring method based on 3D laser scanning technology is proposed for safe and efficient tunnel construction. Greedy triangulation and B-spline interpolation were used to fit the tunnel point cloud and characterize the tunnel deformation. Study: Research on tunnel construction monitoring method based on 3D laser …

Cavity-causing microbes can form superorganisms that can ‘crawl’ and spread on teeth

Leave a Comment / Science / By

Real-time microscopy allowed researchers to track the movement and behavior of a group of fungi and bacteria in the saliva of children with severe dental caries. The interspecific group took on new functions and caused more severe decay than either species alone. Credit: Penn Dental Medicine A cross-kingdom partnership between bacteria and fungi may result …
