Researchers report that mice display behavior that resembles self-recognition when they see themselves in the mirror. When the researchers marked the foreheads of black-furred mice with a spot of white ink, the mice spent more time grooming their heads in front of the mirror -- presumably to try and wash away the ink spot. However, the mice only showed this self-recognition-like behavior if they were already accustomed to mirrors, if they had socialized with other mice who looked like them, and if the ink spot was relatively large.
Scientists have developed a pioneering new method that uses deep learning and a new technique called 'targeted augmentation' to track neurons in moving and deforming animals.
Satellite navigation systems are currently operated by Australia, China, EU, India, Japan, South Korea, Russia, the UK and the US.
ISRO said that in order to continue SHAPE payload for Earth observation, it was decided to re-orbit the PM to a suitable Earth orbit
Aquaporins, which move water through membranes of plant cells, were not thought to be able to permeate sugar molecules, but researchers have observed sucrose transport in plant aquaporins for the first time, challenging this theory.
As humans age, our eyes adjust based on how we use them, growing or shortening to focus where needed, and we now know that blurred input to the eye while the eye is growing causes myopia. It is so specific that the eye grows exactly to compensate for the amount and the direction of blur. Researchers have built a high-frequency ultrasonography system to measure eye size and how quickly eyes grow to better understand myopia and its contributing factors.
A new study concludes that wildfires originating in the western United States and Canada have erased air quality gains over the past two decades and caused an increase of premature deaths in fire-prone areas and downwind regions, primarily in the western U.S.
For the first time, researchers have mapped the financial sector's influence on the emergence of infectious diseases. They find that a relatively small number of powerful financial institutions, such as investment companies, pension funds, and banks could help accelerate actions that mitigate the risks of new pandemics, according to a new study.
Global carbon emissions from fossil fuels have risen again in 2023 -- reaching record levels, according to new research.
An entirely new way to probe how active black holes behave when they eat has been discovered by an international team of astronomers.
The topic of water and the way it can move producing water droplets that leap -- propelled by surface tension -- and frost that jumps -- by way of electrostatics -- is a central focus of a group of scientists. Having incorporated the two phases of liquid and solid in the first two volumes of their research, their third volume investigates a third phase, with boiling water.
As the climate warms, preserving forest cover will be increasingly important for wildlife conservation, finds a study of North American mammals.
To speed up their growth, leukemia cells typically activate the recycling of cellular structures -- enabling them to dispose of defective components and better supply themselves with building materials. Researchers have now shown that leukemia cells with a very common mutation activate specific genes that are important for this recycling process. Their findings open up new therapeutic options for the future.
Physicists have developed a technique with the potential to enhance optical data storage capacity in diamonds. This is possible by multiplexing the storage in the spectral domain.
A new sensor on the submersible Alvin discovered reactive oxygen species for the first time in deep-sea corals, broadening our understanding of fundamental coral physiology.
Utah's variable topography produces a tremendous range of wildfire behavior, according to new research.
A biology student studied more than 600,000 wildlife rehabilitation center records to look at the human impact on wild animals, from lead poisonings to window strikes to vehicle collisions.
Researchers developed a wearable device that can transmit health data 2,400 times the distance of Wi-Fi without significant network infrastructure.
The holiday season is a time for joy and celebration but many Americans admit the endless flurry of activities make it difficult to eat healthy, exercise and get adequate rest, according to a new survey.
Global warming can still be limited to 1.5°C by 2100 while ensuring that the poor are not hit hardest by climate policies and climate impacts. This is achieved by immediately introducing broad carbon pricing together with re-distributive policies using carbon pricing revenues and further measures to reduce energy consumption, accelerate technological transitions, and transform the land sector.
