Researchers present first fossilized 'emperor' butterfly

Butterfly fossils are rare, and finds that preserve fine anatomical details and wing patterns are an absolute exception. An international research team[…] has now described an exceptionally well-preserved [Apaturinae] fossil, approximately 34 to 28 million years old.

Study suggests people are losing 338 spoken words every year and have been for at least 15 years

When we plotted the daily spoken word counts against the year each study was collected, we found a consistent linear decline. Every year, the estimate of daily spoken words dropped by 338. That is how you get from around 16,000 in 2005 to around 12,700 by 2019.

Parasites defy biodiversity rules, thriving far from the equator

Parasite infections in [tropical regions] often lead to higher mortality, which makes it harder for parasites to persist. In cooler temperate waters, hosts can tolerate infections better, giving parasites a chance to survive, reproduce and complete their complex lifecycles.

Scientists uncovered the nutrients bees were missing — Colonies surged 15-fold

Scientists have developed a breakthrough “superfood” for honeybees by engineering yeast to produce the essential nutrients normally found in pollen. In controlled trials, colonies fed this specially designed diet produced up to 15 times more young, showing a dramatic boost in reproduction and overall health.

Motivations behind violent extremism uncovered in new global study

Individuals exhibiting high levels of narcissism and a strong [tendency to manipulate had] strong inclinations toward defensive extremism. [Conversely,] a strong desire for group dominance and high levels of religious fundamentalism were linked to offensive extremism. [Liberal] political group identification was unexpectedly associated with higher offensive but lower defensive intentions[.]

Massive insect body size 300 million years ago may not have been due to high atmospheric oxygen

[The study] found that the space occupied by tracheoles in the flight muscle is typically only 1% or less in most species[.] This suggests that the flight muscles of insects are not constrained by atmospheric oxygen levels as they could easily add tracheoles in the muscle, since they take up so little space.

Highly and casually active citizen scientists contribute equally valuable data

The tendency for people to observe in a particular type of area results in lopsided (biased) data that scientists have to account for when conducting their analyses. […] This study shows that the bias toward natural areas perpetuated by super-users is partly balanced by those of casual users.

Mammal cloning cannot be endless: Mouse line fails at generation 58

In the first few years, the method's success rate steadily [rose, reaching over 15% at one point. After the 25th generation, harmful genetic mutations began to build up], and each new set of mice was less likely to survive. [All] the mice in the 58th generation died shortly after birth.

Bell-bottoms today, miniskirts tomorrow: Math reveals fashion's 20-year cycle

Over the past century, skirt lengths have repeatedly shortened and [lengthened every two decades. But starting] in the 1980s, the data show a wider range of skirt lengths appearing at the same time, suggesting that fashion trends are becoming more fragmented.
