Global importance of pollinators underestimated
(Phys.org) —Declines in populations of pollinators, such as bees and wasps, may be a key threat to nutrition in some of the most poorly fed parts of the globe, according to new research.
Dwindling wind may tip predator-prey balance
Bent and tossed by the wind, a field of soybean plants presents a challenge for an Asian lady beetle on the hunt for aphids. But what if the air—and the soybeans—were still?
A touching story: The ancient conversation between plants, fungi and bacteria
The mechanical force that a single fungal cell or bacterial colony exerts on a plant cell may seem vanishingly small, but it plays a heavy role in setting up some of the most fundamental symbiotic relationships in biology. ...
'K-to-M' histone mutations: How repressing the repressors may drive tissue-specific cancers
In a cell's nucleus, chromosomal DNA is tightly bound to structural proteins known as histones, an amalgam biologists call chromatin. Until about two decades ago, histones were regarded as a nuclear "sidekick," ...
Research helps identify memory molecules
A newly discovered method of identifying the creation of proteins in the body could lead to new insights into how learning and memories are impaired in Alzheimer's disease.
Bats change strategy when food is scarce
Echolocating bats have historically been classified into two groups: 'loud' aerial hawkers who catch flying insects on the wing and 'whispering' gleaners that pick up prey from the ground. While some bat ...
Bluefin tuna found hunting for mackerel in East Greenland waters
On a warm summer day in August 2012, Greenlandic fishermen and biologists caught an unusual catch while conducting an exploratory fishery for mackerel.
Taking the 'sting' out of reproduction
(Phys.org) —Female parasitic wasps have more reproductive success when working together with other females, which can also explain sex biased reproduction, according to new research.
Research sheds light on epilepsy treatments – Why don't the fits stop?
New research from the Royal Veterinary College (RVC) canine epilepsy clinic has shed light on why some dogs do not respond to anti-epilepsy treatments.
Going to extremes for enzymes
In the age-old nature versus nurture debate, Douglas Clark, a faculty scientist with Berkeley Lab and the University of California (UC) Berkeley, is not taking sides. In the search for enzymes that can break ...
Breakthrough study identifies genetic link between the circadian clock and seasonal timing
Researchers from the University of Leicester have for the first time provided experimental evidence for a genetic link between two major timing mechanisms, the circadian clock and the seasonal timer.
Plant engineered for more efficient photosynthesis
(Phys.org) —A genetically engineered tobacco plant, developed with two genes from blue-green algae (cyanobacteria), holds promise for improving the yields of many food crops.
Pig pheromone proves useful in curtailing bad behavior in dogs
A professor at Texas Tech discovers Androstenone can stop dogs from barking, jumping. In a sense, John McGlone was just like any other pet owner a few years ago. He simply wanted to keep his Cairn Terrier from barking incessantly.
