The rise of color vision in animals: Study maps dramatic 100-million-year explosion in color signals
Colors are widely used in communication within and among animal species. For example, peacocks proudly display their vibrant tails, adorned with iridescent eyespots, to attract peahens for courtship. This is a classic example of sexual selection usin.....»»
Airborne microplastics aid in cloud formation
It turns out microplastics have an effect on the weather and climate. Clouds form when water vapor—an invisible gas in the atmosphere—sticks to tiny floating particles, such.....»»
How do brains coordinate activity? From fruit flies to monkeys, scientists discover a universal principle
The brain is a marvel of efficiency, honed by thousands of years of evolution so it can adapt and thrive in a rapidly changing world. Yet, despite decades of research, the mystery of how the brain achieves this has remained elusive......»»

Australian dragon study reveals surprising link between motor systems control and sleep rhythms
Sleep is one of the most mysterious, yet ubiquitous components of our biology. It has been described in all major groups of animals, including worms, jellyfish, insects or cephalopods, and in all vertebrates, from fish to humans. Common characteristi.....»»
Ancient unicellular organism indicates embryonic development might have existed prior to animals" evolution
Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before the appearance of the first animals......»»
Locally optimized urban form can reduce carbon dioxide emissions
Research suggests that urban areas could reduce their carbon dioxide (CO2) emissions by optimizing their urban form. However, the relationship between urban form and emissions is highly context-dependent and generalizations cannot be made......»»

Mighty radio bursts linked to massive galaxies: New clues about how magnetars form
Since their discovery in 2007, fast radio bursts—extremely energetic pulses of radio-frequency light—have lit up the sky repeatedly, leading astronomers on a chase to uncover their origins. Currently, confirmed fast radio bursts, or FRBs, number.....»»
Quantum vortices confirm superfluidity in supersolid
Supersolids are a new form of quantum matter that has only recently been demonstrated. The state of matter can be produced artificially in ultracold, dipolar quantum gases. A team led by Innsbruck physicist Francesca Ferlaino has now demonstrated a m.....»»
New research reveals how stormy conditions affect albatrosses" ability to feed
Albatrosses are exceptionally mobile and use the wind to travel hundreds of thousands of miles to feed on squid, fish, or other animals found near the water surface in the open ocean. In fact, some larger species of albatrosses are so reliant on the.....»»
Cells have more mini "organs" than once thought—these rogue organelles challenge biology"s fundamentals
Think back to that basic biology class you took in high school. You probably learned about organelles, those little "organs" inside cells that form compartments with individual functions. For example, mitochondria produce energy, lysosomes recycle wa.....»»
