Jellyfish and flies use the same hormone when they’ve had enough to eat
The regulation of hunger may go back to the base of the animal family tree. Enlarge / A Moon jellyfish. (credit: Dan Kitwood / Getty Images) The sensation of hunger seems pretty simple on the surface, but behind the sce.....»»
The robber fly is an aerodynamic acrobat that can catch its prey in midflight
Roboticists can learn a lot about avoiding obstacles while pursuing a target from the flies. Enlarge / A miniature predatory robber fly (Holcocephala fascia) feeds on a captured rove beetle. A new study reveals that the fly approaches.....»»
Herbicide residues in soil affect hormone levels in crop plants
A new study finds that glyphosate residues in soil affect phytohormones in aboveground plant parts. Academy of Finland funded postdoctoral researcher Dr. Benjamin Fuchs investigates the effects of herbicide residues in soil on plant physiology and ch.....»»
Plant smoke detectors evolve as hormone sensors
Wildfires are devastating, but they can also bring new life by clearing existing vegetation and allowing new plants to spring up. Many plants in fire-prone areas actually require exposure to fire for seeds to germinate. In the past decade, scientists.....»»
DARPA Flies a Black Hawk Helicopter Without a Pilot For 30 Minutes
The Defense Advanced Research Projects Agency has flown a UH-60A Black Hawk helicopter without a pilot for the first time ever. CNET reports: DARPA's Aircrew Labor In-Cockpit Automation System program was used to fly the helicopter on autopilot over.....»»
GoPro keeps recording as parrot steals it from tourists and flies off
A GoPro camera captured a bird’s-eye view of a New Zealand national park when a mischievous parrot nabbed the device and flew off......»»
Are scientists being fooled by bacteria?
For decades, a small group of cutting-edge medical researchers have been studying a biochemical, DNA tagging system, which switches genes on or off. Many have studied it in bacteria and now some have seen signs of it in, plants, flies, and even human.....»»
How your culture informs the emotions you feel when listening to music
I open my eyes to the sound of a voice as the twin-engine Pakistan Airlines propeller aircraft flies through the Hindu Kush mountain range, west of the mighty Himalayas. We are cruising at 27,000 feet, but the mountains around us appear worryingly cl.....»»
Experiments with fruit flies suggest learning differences might involve more than just nature versus nurture
A team of researchers from Harvard University, the Ann and Robert H. Lurie Children's Hospital of Chicago and the Howard Hughes Medical Institute reports evidence that certain learning differences between individuals of the same species might involve.....»»
Mapping the olfactory system in fruit flies
The distinctive smell of a flower… the unmistakable aroma of coffee… the dangers linked with inhaling smoke fumes. Sensory systems have evolved to provide us with immediate, finely tuned information about the world around us, whether they are col.....»»

Nanotherapy offers new hope for the treatment of Type 1 diabetes
Individuals living with Type 1 diabetes must carefully follow prescribed insulin regimens every day, receiving injections of the hormone via syringe, insulin pump or some other device. And without viable long-term treatments, this course of treatment.....»»
Team succeeds in culturing the pygmy zebra octopus
For generations, scientists have relied on a handful of organisms to study the fundamentals of biology. The usual suspects—fruit flies, zebrafish, and mice, among others—all have short lifespans, small body size, can be bred through multiple gene.....»»
How diet influences taste sensitivity and preference
What you eat influences your taste for what you might want to eat next. So claims a University of California, Riverside, study performed on fruit flies. The study offers a better understanding of neurophysiological plasticity of the taste system in f.....»»
How a fly"s brain calculates its position in space
Navigation doesn't always go as planned—a lesson that flies learn the hard way, when a strong headwind shunts them backward in defiance of their forward-beating wings. Fish swimming upriver, crabs scuttling sideways, and even humans hanging a left.....»»
A Gene-Tweaked Jellyfish Offers a Glimpse of Other Minds
Researchers have created jellyfish whose nerve cells light up when they fire, offering a tantalizing view of neurology before the rise of the brain......»»
Researchers identify and characterize a sour receptor conserved from fruit flies to humans
Humans and fruit flies respond to many of the same tastes—sweet, salty, bitter and so on. The receptors that identify these substances, however, are very different between us and insects. Except when it comes to sour......»»
Newly identified hormone may be a critical driver of type 1 and type 2 diabetes
A newly discovered hormone named fabkin helps regulate metabolism and may play an important role in the development of both type 1 and type 2 diabetes, according to new research......»»
Aging stiffens the blood vessels but their flexibility also fluctuates based on a woman’s hormone state
A study measured arterial stiffness in women from wide age range. Increased stiffness is an independent risk factor for cardiovascular disease. Age was a strong determinant of arterial stiffness. Indicative of the role of hormones, menstrual cycle ph.....»»
Melatonin exacerbates asthma, study finds
Asthma sufferers generally find their condition gets worse at night. Now researchers may understand why. Melatonin, a sleep hormone that is sometimes prescribed to treat insomnia, exasperates the constriction of the bronchus -- the pathway that moves.....»»
