Consistent metabolism may prove costly for insects in saltier water
Increased salinity usually spells trouble for freshwater insects like mayflies. A new study finds that the lack of metabolic responses to salinity may explain why some freshwater insects often struggle in higher salinity, while other freshwater inverte…
Fathers’ parental leave might protect men against alcohol-related morbidity
Men who have been on parental leave have a significantly reduced risk of being hospitalized due to alcohol consumption, according to a new study from Sweden.
Astronomers discover first step toward planet formation
Astronomers have gotten very good at spotting the signs of planet formation around stars. But for a complete understanding of planet formation, we also need to study examples where planet formation has not yet started. Looking for something and not fin…
Scientists discover ‘long colds’ may exist, as well as long Covid
A new study has found that people may experience long-term symptoms — or ‘long colds’ — after acute respiratory infections that test negative for COVID-19.
Deciphering the intensity of past ocean currents
Ocean currents determine the structure of the deep-sea ocean floor and the transport of sediments, organic carbon, nutrients and pollutants. In flume-tank experiments, researchers have simulated how currents shape the seafloor and control sediment depo…
How bacteria can organize themselves
Structural patterns can be created due to the chasing interactions between two bacterial species. In a new model, scientists describe how interactions on the individual level can result in a global self-organization of species. Their findings provide i…
Ginger pigment molecules found in fossil frogs
Palaeontologists discover molecular evidence of phaeomelanin, the pigment that produces ginger coloration. Phaeomelanin is now toxic to animals – this discovery may be first step in understand its evolution.
Pulsars may make dark matter glow
The central question in the ongoing hunt for dark matter is: what is it made of? One possible answer is that dark matter consists of particles known as axions. A team of astrophysicists has now shown that if dark matter consists of axions, it may revea…
Researchers create a neural network for genomics — one that explains how it achieves accurate predictions
A team of computer scientists has created a neural network that can explain how it reaches its predictions. The work reveals what accounts for the functionality of neural networks–the engines that drive artificial intelligence and machine learning–th…
Thalamus regulates adaptability of the adult brain
It is generally believed that the adaptability of the adult brain mainly takes place in the cortex. However, a new study shows that the thalamus, a relay station for incoming motor and sensory information, plays an unexpectedly important role in this p…
How male mosquitoes compensate for having only one X chromosome
Researchers have discovered the master regulator responsible for balancing the expression of X chromosome genes between males and females in the malaria mosquito. This discovery helps scientists better understand the evolution of the epigenetic mechani…
How do our brains tell us what went wrong?
A team of neuroscientists has now identified a class of neurons–what it calls ‘prediction-error neurons’–that are not responsive to sounds in general, but only respond when sounds violate expectations, thereby sending a message that a mistake has bee…
Climate change brings earlier arrival of intense hurricanes
New research has revealed that since the 1980s, Category 4 and 5 hurricanes (maximum wind speed greater than 131 miles per hour) have been arriving three to four days earlier with each passing decade of climate change.
Natural GM crops: Grasses take evolutionary shortcut by borrowing genes from their neighbors
Grass may transfer genes from their neighbors in the same way genetically modified crops are made, a new study has revealed.
