Birdwatching brings millions of dollars to Alaska
A committed and lucky birdwatcher in Alaska may see an elusive bluethroat north of the Brooks Range, catch a glimpse of the bold markings on a harlequin duck as it zips along an Interior river, encounter all four species of eider in Utqiaġvik, or take in the sounds of thousands of feeding shorebirds in the Copper River Delta.
Toads surprise scientists by climbing trees in UK woodlands
Volunteers surveying dormice and bats in trees have made the unexpected discovery of over fifty common toads in nest boxes and tree cavities at least 1.5 meters high

Older people with hypothyroidism, also called underactive thyroid, may be at increased risk of developing dementia, according to a new study. The risk of developing dementia was even higher for people whose thyroid condition required thyroid hormone replacement medication.
Researchers decode retinal circuits for circadian rhythm, pupillary light response

Researchers used a fiber optic cable on the ice cap of an Icelandic subglacial volcano to detect low-frequency volcanic tremor, suggesting this technology could be useful in monitoring other ice-covered volcano systems.
Upside-down design expands wide-spectrum super-camera abilities
- ScienceDaily
- 22/7/6 22:54
By turning the traditional lab-based fabrication process upside down, researchers have greatly expanded the abilities of light-manipulating metasurfaces while also making them much more robust against the elements. The combination could allow these quickly maturing devices to be used in a wide range of practical applications, such as cameras that capture images in a broad spectrum of light in a...
