Why can zebrafish regenerate damaged heart tissue, while other fish species cannot?
A heart attack will leave a permanent scar on a human heart, yet other animals, including zebrafish, can clear cardiac scar tissue and regrow damaged muscle as adults. Biologists sheds new light on how zebrafish heal heart tissue by comparing how this species responds to heart
The Shark Whisperer
Donald Nelson spent his life undoing the damage that Jaws did to the perception of sharks. The post The Shark Whisperer appeared first on Nautilus .
Bike Bus gains supporters as a way to promote sustainable and safe mobility
The Bike Bus movement has emerged as a powerful tool to promote road safety, sustainability and community. According to a global survey carried out by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB), the phenomenon has
Study presents new perspective on morality based on nuances in values among different political ideologies
While social psychology has long been interested in learning more about how one's moral values relate to one's political views, most of the research to date has used quite the same perspective.
Marine microbial populations: Potential sensors of the global change in the ocean
Animal and plant populations have been extensively studied, which has helped to elucidate ecosystem processes and evolutionary adaptations. However, this has not been the case with microbial populations, due to the impossibility of isolating, culturing and analyzing the genetic
Unraveling the mysteries of consecutive atmospheric river events
In California's 2022-2023 winter season, the state faced nine atmospheric rivers (ARs) that led to extreme flooding, landslides, and power outages—the longest duration of continuous AR conditions in the past 70 years. Scientists at Lawrence Berkeley National Laboratory
Research team resolves decades-long problem in microscopy
When viewing biological samples with a microscope, the light beam is disturbed if the lens of the objective is in a different medium than the sample. For example, when looking at a watery sample with a lens surrounded by air, the light rays bend more sharply in the air around
Octopus inspires new suction mechanism for robots
A new robotic suction cup which can grasp rough, curved and heavy stone, has been developed by scientists.
Teaching a computer to type like a human
A new typing model simulates the typing process instead of just predicting words.
Mutations in noncoding DNA become functional in some cancer-driving genes
Despite progress in defining functional elements of noncoding DNA, it is still not fully understood. Researchers, using an experiment that elucidated the function of tens of thousands of noncoding variants, discovered a link between functional mutations and genes linked to
Coal train pollution increases health risks and disparities
The first health impact study of coal train pollution centers on the San Francisco Bay Area, with scientists finding communities near passing coal trains suffer worse health outcomes.
When thoughts flow in one direction
Contrary to previous assumptions, nerve cells in the human neocortex are wired differently than in mice. The study found that human neurons communicate in one direction, while in mice, signals tend to flow in loops. This increases the efficiency and capacity of the human brain
Mess is best: Disordered structure of battery-like devices improves performance
The energy density of supercapacitors -- battery-like devices that can charge in seconds or a few minutes -- can be improved by increasing the 'messiness' of their internal structure. Researchers used experimental and computer modelling techniques to study the porous carbon
Skyrmions move at record speeds: A step towards the computing of the future
Scientists have discovered that the magnetic nanobubbles known as skyrmions can be moved by electrical currents, attaining record speeds up to 900 m/s. Anticipated as future bits in computer memory, these nanobubbles offer enhanced avenues for information processing in
One third of China's urban population at risk of city sinking, new satellite data shows
Land subsidence is overlooked as a hazard in cities, according to new research. Scientists used satellite data that accurately and consistently maps land movement across China.
Novel material supercharges innovation in electrostatic energy storage
Scientists have developed artificial heterostructures made of freestanding 2D and 3D membranes that have an energy density up to 19 times higher than commercially available capacitors.
A common pathway in the brain that enables addictive drugs to hijack natural reward processing
Researchers have uncovered a mechanism in the brain that allows cocaine and morphine to take over natural reward processing systems.
Research suggests ways to ensure more sustainability in global agricultural trade
The EU wants to ensure greater sustainability in agricultural trade with the Global South—with the aim of minimizing the environmental and climate-damaging effects of importing crops such as soya, palm oil, coffee, and cocoa. However, this aspiration is often not fulfilled in
Using deep learning to image the Earth's planetary boundary layer
Although the troposphere is often thought of as the closest layer of the atmosphere to the Earth's surface, the planetary boundary layer (PBL)—the lowest layer of the troposphere—is actually the part that most significantly influences weather near the surface. In the 2018
Stars vs. numbers: How consumers perceive online rating formats
Mathematically speaking, scoring 3.5 out of 5 is the same as receiving three and a half stars on a five-star scale. But visually speaking, the numbers don't add up.
RNA's hidden potential: New study unveils its role in early life and future bioengineering
The beginning of life on Earth and its evolution over billions of years continue to intrigue researchers worldwide. The central dogma or the directional flow of genetic information from a deoxyribose nucleic acid (DNA) template to a ribose nucleic acid (RNA) transcript, and
New study shows how quickly surface water moves to groundwater reservoirs across Australia
A new study from Charles Darwin University (CDU), Monash University and The University of Newcastle has presented almost 100,000 estimates of groundwater recharge rates across Australia, by far the largest known database of its kind.
Q&A: Why are we drowning in single-use plastics, and what can we do about it?
Plastic is ubiquitous. It's in the clothes we wear, wrapped around the food we eat and in the toothpaste we use. It floats in the oceans and litters the snow on Mount Everest.
Respiratory stress response that stunts temperate fish also affects coral reef fish
Coral reef fish, like the fish in other marine and freshwater ecosystems, are likely to reach smaller maximum sizes and start reproducing earlier with smaller and fewer eggs as climate change continues to warm up the ocean.
Fourteen years after the Gulf of Mexico oil spill, endemic fishes face an uncertain future
The 2010 Gulf of Mexico Deepwater Horizon was the largest accidental oil spill in history. With almost 100 million gallons (379 million liters) of oil combined with dispersants suggested to remain in the Gulf, it is one of the worst pollution events ever. More than a decade
