Fruit flies adapt activity to 'white nights'

Evolution takes place constantly, everywhere in nature. Nevertheless, it is always exciting for biologists to observe evolution "in real time." One such opportunity for observation is currently being presented by the internal ...

Whether caribou migrate or stay put is determined by genes that evolved in the last ice age

When talking about caribou, most people probably think of some version of Santa Claus's reindeer. Although real-life reindeer sadly do not exhibit any of the fantastical traits associated with helping Santa deliver gifts ...

New findings on the internal clock of the fruit fly

Most living organisms have an internal clock which, among other things, controls the sleep-wake rhythm. The internal rhythm lasts approximately one day (circadian), i.e. about 24 hours, and is regulated by means of various ...

Corals may look healthy, but coastal urbanization is destroying their delicate biorhythm

Coral reefs in the Gulf of Eilat (also known as the Gulf of Aqaba) have been proven particularly resistant to global warming, rising water temperatures and bleaching events that are crippling their counterparts elsewhere ...

Study finds links between circadian rhythms, metabolism and addiction

A new University of California, Irvine-led study establishes important conceptual connections between the fields of circadian rhythms, metabolism, and addiction. Going beyond current studies on substance use disorders, which ...

SRC-3 is a key regulator of the 12-hour clock

Many people have heard of the circadian rhythms or biological processes that follow a 24-hour cycle. Sleeping at night and being awake during the day is a well-known example of a circadian rhythm. Less well known are the ...

Device enables researchers to easily track elusive insects

With some home security software and a little ingenuity, researchers have developed an inexpensive device that will allow them to study the behavior and activity of insects in regions of the world where they're most diverse.

Government guidelines insufficient to protect freshwater ecosystem from salt pollution

Current water quality guidelines aren't protecting freshwater ecosystems from increasing salt pollution due to road de-icing salts, agriculture fertilizers, and mining operations, according to an international study that ...

Temperature and reproduction link holds promise for insect control

Scientists have uncovered a set of neurons in fruit flies that shut down in cold temperatures and slow reproduction, a system conserved in many insects, including mosquitoes, which could provide a target for pest control.
