Mice pass the mirror test, a classic indicator of self-recognition

Science Daily - 05/12/2023
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.

Sugar permeation discovered in plant aquaporins

Science Daily - 05/12/2023
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.

A farsighted approach to tackle nearsightedness

Science Daily - 05/12/2023
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.

Wildfires have erased two decades' worth of air quality gains in western United States

Science Daily - 05/12/2023
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.

Powerful financial giants could play vital role in preventing the next pandemic

Science Daily - 05/12/2023
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.

An entirely new way to probe how active black holes behave when they eat has been discovered by an international team of astronomers.

Boiled bubbles jump to carry more heat

Science Daily - 05/12/2023
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.

In hotter regions, mammals seek forests, avoid human habitats

Science Daily - 05/12/2023
As the climate warms, preserving forest cover will be increasingly important for wildlife conservation, finds a study of North American mammals.

Leukemia cells activate cellular recycling program

Science Daily - 05/12/2023
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.

Optical data storage breakthrough

Survey finds Americans struggle to maintain healthy habits during the holiday season

Science Daily - 05/12/2023
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.

1.5°C pathways can still be achieved, combining fairness and global climate protection

Science Daily - 05/12/2023
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.
