Urban great tits less stressed than their countryside cousins, finds study
"The great tit's high cognitive capacity means it is highly adaptable, and urban great tits seem to have adapted so well to the new environment that they are not stressed by high population density. Another possible explanation is that it was the most intelligent and most flexible individuals who succeeded in colonizing urban environments in the first place," says Anders Brodin, biologist at Lund University.

Climate change has increased diversity of butterflies in Sweden and Finland, may have major ecosystem consequences
New research shows that butterflies have expanded their ranges over the past 120 years to cope with a warmer climate in Sweden and Finland. Although driven by a warmer climate, range expansions have also been influenced by human land use and vary according to species thermal tolerances and habitat preferences.

How seeing corpses reduces the lifespan of flies
Researchers led by Christi Gendron at the University of Michigan have found the link between death perception and reduced aging in flies. [A] specific group of brain cells in the fly, called R2 and R4 neurons, are activated when flies encounter other dead flies, and that this increased activity leads to more rapid aging.

Cause and Cure Discovered for Common Type of High Blood Pressure
The cause is a tiny benign nodule, present in one-in-twenty people with hypertension. The nodule produces a hormone, aldosterone, that controls how much salt is in the body. […] The researchers also discovered that this form of hypertension could be cured by unilateral adrenalectomy – removing one of the two adrenal glands.

HS Ympäristö | Tuulivoimala voi olla kotkalle kohtalokas – jo kymmeniä kuolleita lintuja löydetty
Tuulivoimalan silpomaksi on Suomessa päätynyt tiettävästi 48 merikotkaa, kertoo Hannu Tikkanen Metsähallituksesta. […] Tiettävästi yhtään maakotkaa ei ole vielä Suomessa kuollut tuulivoimalatörmäyksessä, sillä nykyisiä voimaloita ei juuri ole niiden reviireillä.

Hidden carbon: Fungi and their ‘necromass’ absorb one-third of the carbon emitted by burning fossil fuels every year
[New] research shows [mycorrhizal fungi] may quietly be playing a bigger role in storing carbon than we thought. [Researchers] estimate the world's plants are transferring a staggering 3.58 billion tonnes of carbon per year to this underground network.
