Identifying and delineating cell structures in microscopy images is crucial for understanding the complex processes of life. This task is called 'segmentation' and it enables a range of applications, such as analyzing the reaction of cells to drug treatments, or comparing cell structures in different genotypes. It was already possible...
‘Smarts’ count: Evolution of intelligence
The Beatles said it best: Love is all you need. And according to new research, the same may be true in the animal kingdom. Well, at least for mosquitofish -- a matchstick-sized fish endemic to Central America and now found globally. According to the scientists, male mosquitofish possess impressive problem-solving...
Some animals cooperate with members of other species
Some animals are capable of cooperating with members of other species. An interdisciplinary team explores the cognitive underpinnings of such cross-species collaborations, opening up a new perspective on the evolution of intelligence and cooperation in the animal kingdom.
Giant ice bulldozers: How ancient glaciers helped life evolve
New research has revealed how massive ancient glaciers acted like giant bulldozers, reshaping Earth's surface and paving the way for complex life to flourish. By chemically analyzing crystals in ancient rocks, the researchers discovered that as glaciers carved through the landscape, they scraped deep into the Earth's crust, releasing key...
Africa set to reach 1.5 C climate change threshold by 2040 even under low emission scenarios
New research suggests that all five subregions of Africa will breach the 1.5 C climate change threshold -- the limit stipulated by the Paris Agreement -- by 2040 even under low emission scenarios.
Mimicking shark skin to create clean cutting boards
Keeping work surfaces clean during meat processing is a challenge, and now researchers deliver key insights into a solution that could change the current practice altogether: Instead of working to prevent bacteria buildup, they created surfaces that stop bacteria from attaching in the first place. Using lasers to etch and...
New study reveals Neanderthals experienced population crash 110,000 years ago
A new study suggests that Neanderthals experienced a dramatic loss of genetic variation during the course of their evolution, foreshadowing their eventual extinction. Examination of semicircular canals of ear shows Neanderthals experienced 'bottleneck' event where physical and genetic variation was lost.
DNA origami suggests route to reusable, multifunctional biosensors
A team has used a process known as DNA origami to make electrochemical sensors that can quickly detect and measure biomarkers.
Beehive sensors offer hope in saving honeybee colonies
A computer science team has developed a sensor-based technology that could revolutionize commercial beekeeping by reducing colony losses and lowering labor costs. The technology uses low-cost heat sensors and forecasting models to predict when hive temperatures may reach dangerous levels. The system provides remote beekeepers with early warnings, allowing them...
Honeybee dance ‘styles’ sway food foraging success
Biologists have learned several interesting patterns related to bee communication. One such observation was that bees have consistent, unique ways of dancing, meaning each bee has its own 'style' that it adds to the communication. Could the success of the waggle dance be related to this uniqueness? Would bees that...
