What octopus and human brains have in common

Cephalopods like octopuses, squids and cuttlefish are highly intelligent animals with complex nervous systems. In Science Advances, a team led by Nikolaus Rajewsky of the Max Delbrück Center has now shown that their evolution is linked to a dramatic expansion of their microRNA repertoire.

Project aims to use concrete reefs to increase marine biodiversity off the Danish coast

When cycling across the Bryggebroen bridge at Fisketorvet, you see three concrete sculptures emerging from the water surface in the inner harbor of Copenhagen. But it is actually only when you get under water that the work of art really begins to come to life. Here you can see that the sculptures are filled with cracks that will eventually become a habitat for seaweed and fish.

Synchronizing chaos through a narrow slice of the spectrum

The abstract notion that the whole can be found in each part of something has for long fascinated thinkers engaged in all walks of philosophy and experimental science, from Immanuel Kant on the essence of time to David Bohm on the notion of order, and from the self-similarity of fractal structures to the defining properties of holograms.

Developing a sensor to detect disease-transmitting mosquitoes

Mosquitoes inhabit various world regions, with more than 3,000 species already identified. Some of these are transmission vectors of several diseases, such as malaria, yellow fever, or dengue. According to the World Health Organization, 627,000 people died of malaria in 2020.

Study: Climate change is increasing the frequency and temperature of extreme heat waves

As California awakens to the worsening risk of extreme climate events, researchers are shedding new light on last year's anomalous and extreme Pacific Northwest heat wave. One study published this week said such heat waves could become 20 times more likely to occur if current carbon emissions continue unabated. Another said they may also be nearly 10 degrees hotter.

AI tailors artificial DNA for future drug development

With the help of an AI, researchers have succeeded in designing synthetic DNA that controls the cells' protein production. The technology can contribute to the development and production of vaccines, drugs for severe diseases, as well as alternative food proteins much faster and at significantly lower costs than today.

525-million-year-old fossil defies textbook explanation for brain evolution

According to a new study, fossils of a tiny sea creature with a delicately preserved nervous system solve a century-old debate over how the brain evolved in arthropods, the most species-rich group in the animal kingdom. Combining detailed anatomical studies of the fossilized nervous system with analyses of gene expression patterns in living descendants, they conclude that a shared blueprint of...

Stop counting cups: There's an ocean of difference in our water-drinking needs

A new study of thousands of people reveals a wide range in the amount of water people consume around the globe and over their lifespans, definitively spilling the oft-repeated idea that eight, 8-ounce glasses meet the human body's daily needs. Differences in environment, body composition and activity level contribute to daily water turnover of as little as 1 liter and as much as 10 liters.
