Study shows example of mammal adapting to fires by increasing torpor time
New terahertz device could strengthen security
We are all familiar with the hassles that accompany air travel. We shuffle through long lines, remove our shoes, and carry liquids in regulation-sized tubes. And even after all the effort, we still wonder if these procedures ...
How rodents bulk up for winter without going nuts
When Arctic ground squirrels need to bulk up for winter, they get a boost from an enormous spike in the levels of steroids in their blood. So why doesn't it lead to 'roid rage?
Herbivore drool defeats fungal defence
A report in Biology Letters shows that the drool of herbivores might help defeat the toxic fungal defences of the plants they graze on.
The weird world of nuptial gifts
An opinion piece published in Biology Letters today delves into the weird world of nuptial gifts.
Trapping light: A long lifetime in a very small place
Physicists at the University of Rochester have created a silicon nanocavity that allows light to be trapped longer than in other similarly-sized optical cavities. An innovative design approach, which mimics ...
Researchers create 'ultrasonic hands' that can grip microparticles
(Phys.org) —A team of researchers from the Universities of Bath, Bristol and Dundee has discovered for the first time that ultrasonic waves can be used to grab several microparticles at a time, effectively ...
New application of physics tools used in biology
A Lawrence Livermore National Laboratory physicist and his colleagues have found a new application for the tools and mathematics typically used in physics to help solve problems in biology.
First in non-primates: Research shows jackdaws use eyes for communication
Researchers in Cambridge and Exeter have discovered that jackdaws use their eyes to communicate with each other – the first time this has been shown in non-primates.
Landscape complexity affects pigeons' navigation
(Phys.org) —Homing pigeons' ability to learn and remember routes depends on the complexity of the landscape below. Hedges and boundaries between urban and rural areas provide ideal landmarks for navigation.
Natural selection can favor 'irrational' behavior
It seems paradoxical that a preference for which of two houses to buy could depend on another, inferior, house – but researchers at the University of Bristol have identified that seemingly irrelevant alternatives can, and ...
Ignorance is sometimes bliss
A range of examples suggests a lack of information about their fellows can favor cooperation and prevent conflict among animals—and even among genes.
Fast detector for a wide wavelength range
Free-electron lasers are extremely versatile research tools because their intense, super short light flashes permit a closer look at new materials and even biological molecules; thus, allowing effects to ...
One tree's architecture reveals secrets of a forest, study finds
(Phys.org) —Behind the dazzling variety of shapes and forms found in trees hides a remarkably similar architecture based on fundamental, shared principles, UA ecologists have discovered.
