Why petting your cat leads to static electricity

Researchers at Northwestern University have finally uncovered the mechanics of static electricity generated by rubbing objects together, explaining how forces on different parts of an object create electrical charges and a current. This breakthrough could lead to new solutions for industrial fires, pharmaceutical dosing, and other issu...

Crude oil decimates sea otter buoyancy

Research reveals that crude oil pollution dramatically reduces sea otter fur buoyancy, placing newborn pups at risk due to their larger surface area relative to body mass. After cleaning, the buoyancy of the fur improves but not fully recovers, highlighting the need for thorough detergent rinsing.

Social rank may determine if animals live fast, die young

A Dartmouth study suggests that social rank determines whether animals prioritize short-term energy consumption over long-term health, with dominant monkeys consuming food quickly to maintain dominance, while lower-ranked monkeys invest time in washing their food to prevent tooth damage. The findings shed light on the disposable soma h...

Breakthrough wildlife tracking technology that adheres to fur delivers promising results from trials on wild polar bears

A new tracking technology that adheres to a polar bear's fur has shown promise in studying the behavior and movements of subadult and adult male bears. The technology, known as Burr on Fur, allows researchers to track these groups without the need for satellite collars, providing valuable insights into their habits.

Genetic patterns of world’s farmed, domesticated foxes revealed via historical deep-dive

A team of researchers uncovered the geographical origins of farmed foxes and understood the role of genetic diversity in their domestication. The study found that every captive population originated from wild North American foxes, with greater genetic diversity observed in Eurasian populations.

High-status Danish Vikings wore exotic beaver furs

Researchers analyzed ancient proteins in high-status Viking graves to identify beaver fur, supporting the idea that it was a luxury item. The discovery suggests that wearing exotic fur was an obvious visual statement of affluence and social status during the Viking Age.

Monkeys appreciate lifelike animation

Researchers found that Rhesus monkeys avoid lifeless monkey faces but show social facial expressions towards a natural-looking avatar with fur and details. The study suggests using this type of avatar in social cognition studies for standardization and replicability.

Australian fur seal pup population is shrinking

A long-term monitoring program for Australian fur seals has tracked a decline in pup populations, with the first reduction since species-wide protection was implemented in 1975. The study highlights the importance of regularly assessing monitoring programs and provides valuable information on how to improve them.

Bleats and trills evolved multiple times to aid in 'caller ID'

Researchers found that vibrato-like frequency modulation improves the detection of formants, key acoustic components encoding animal size and identity. This mechanism has independently evolved in six mammalian orders, suggesting its importance for transmitting information about an individual's size and identity through calls.

Seal pups listen for long distance calls to locate their mothers

Antarctic fur seal pups identify their mothers by detecting the mother's vocal pitch at longer distances and using other components of the vocal signature at closer range. The study found that frequency modulations propagate reliably up to 64 meters, while amplitude modulations are degraded for distances over 8 meters.

Scent matters to fur seals

Researchers at Bielefeld University discovered that Antarctic fur seals have a unique 'scent profile' that enables them to identify their offspring and family members. This finding suggests that scent plays a crucial role in the animals' social behavior, particularly in recognizing kin and selecting mates.
