Moths use ultrasound to defend against bats
While a clear night sky might seem quiet and peaceful to us, empty of everything but stars, this nocturnal world is filled with a high-pitched cacophony of sound just beyond our ability to hear. Bats pierce the shadows with ultrasonic pulses that ena.....»»
Examining the effects of ultrasound-assisted fermentation on Chinese rice wine
Traditional Chinese rice wine (RW) has been popular in China for thousands of years. The brewing process involves simultaneous saccharification and solid-state fermentation using mixed saccharifying starters, such as wheat starter and distiller's yea.....»»
New nuclear deflection simulations advance planetary defense against asteroid threats
Researchers at Lawrence Livermore National Laboratory (LLNL) have developed a modeling tool for assessing the potential use of a nuclear device to defend the planet against catastrophic asteroid impacts......»»
Bats declined as Britain felled trees for colonial shipbuilding, says new study
Bat numbers declined as Britain's trees were felled for shipbuilding in the early colonial period, new research shows. The work is published in the Journal of Applied Ecology......»»
Glassy shell of microscopic algae inspires tiny ultrasound detectors for medical imaging
A multidisciplinary team of researchers from Skoltech has discovered the resonance frequencies of diatom frustules. These intricately structured silicon dioxide shells of single-celled microalgae provide a promising model for nature-inspired electron.....»»
Migratory bats can detect the Earth"s magnetic field, behavioral experiments show
Pipistrelle bats have a magnetic compass and calibrate it at sunset, according to a new study. An international team of researchers led by the University of Oldenburg has used behavioral experiments to show that two different components of the Earth'.....»»
Methane emissions from Dutch canals underestimated, researcher finds
Researchers have so far underestimated methane emissions from canals in five major Dutch cities. That is the conclusion of microbiologist Koen Pelsma, who will defend his Ph.D. thesis on this topic at Radboud University on 13 December......»»
Much effort, little prey: Poor foraging success drives bats away from cities
While some wildlife species thrive well in cities, it's harder for large, insectivorous bat species to find enough food. To get their fill, city-dwelling common noctules (Nyctalus noctula) have to hunt longer than their rural counterparts and yet the.....»»

Study: The serotine bat uses its super-large penis as an arm when mating
Further research involves building a "bat porn box" to catch more mating acts on camera. Enlarge / "That's not my arm": Male serotine bats have such large penises, they can use them as an arm while mating. (credit: Alona Shulenko.....»»
Research links climate change to vampire bat expansion and rabies virus spillover
Vampire bats may soon take up residence in the United States and bring with them an ancient pathogen. "What we found was that the distribution of vampire bats has moved northward across time due to past climate change, which has corresponded with an.....»»
Study of wintering sites shows bat seasonal migration is more complex than previously assumed
In late summer, some bat species migrate from northern Europe along the coastlines to their wintering sites in central and western Europe. Until now it was assumed that all bats traveled in the same direction during the migration. However, the realit.....»»
Caught in living cells: How bacteria regulate their genes to defend themselves
For the first time, it was shown in living cells how the bacterium E. coli regulates genes that help it survive in a new environment. Biochemist Fatema Zahra Rashid managed to do this using a technique she fine-tuned. Her research into changes in 3-d.....»»
Acoustic diffraction-resistant adaptive profile technology for elasticity imaging
Acoustic beam shaping with high degrees of freedom is critical for ultrasound imaging, acoustic regulation, and stimulation. The ability to fully regulate the acoustic pressure profile relative to its propagation path remains to be achieved......»»
These bats use their penis as an "arm" during sex but not for penetration
Mammals usually mate via penetrative sex, but researchers report Nov. 20 in the journal Current Biology that a species of bat, the serotine bat, (Eptesicus serotinus) mates without penetration. This is the first time non-penetrative sex has been docu.....»»
