Today’s Image of the Day from European Space Agency features the first image of the full Earth disc from the Meteosat Third Generation Imager.
This is the first of a new generation of satellites that is expected to revolutionize weather forecasting by enabling more precise monitoring of our changing atmosphere, land and oceans.
Simonetta Cheli, ESA’s Director of Earth Observation Programmes, said that the image is a great example of what European cooperation in space can achieve.
Google will soon require that political ads using artificial intelligence be accompanied by a prominent disclosure if imagery or sounds have been synthetically altered.
The discovery surprised scientists when researchers in Israel recently consulted them for their expertise on specialized cells called M cells.
M cells act as gatekeepers for the immune system in organs like the intestine and lungs. They play a crucial role in delivering specialized antigen cells during the development of the body’s immune system.
In the mouse study on the thymic epithelium, researchers at the Weizmann Institute of Science in Israel wanted to determine the function of M cells in the gut and airways.
The bubble itself is composed of previously identified structures that themselves have been considered some of the universe’s largest arrangements of matter. This includes several superclusters, or groups of galaxy clusters, that each contain 10 clusters and span up to 200 million light-years. At the heart of Ho’oleilana lies the Bootes supercluster and the Bootes void, which is a 330 million-light-year-wide space of nothingness.

“We were not looking for it. It is so huge that it spills to the edges of the sector of the sky that we were analyzing,” Brent Tully, study leader and an astronomer at the University of Hawaii, said in a statement. “As an enhancement in the density of galaxies, it is a much stronger feature than expected. The very large diameter of one billion light years is beyond theoretical expectations.”
Summary: The blood-brain barrier (BBB) in carpenter ants isn’t just a protective boundary, but actively shapes ant behavior.
The BBB produces an enzyme called Juvenile hormone esterase (Jhe) that degrades the Juvenile Hormone (JH3), which promotes foraging behavior. The presence and degradation of JH3 by the BBB helps determine whether an ant becomes a forager or soldier.
Interestingly, similar mechanisms might influence mouse behavior, hinting at broader implications beyond ants.
Year 2020 The ecology of the human brain is so complex that it even seems like it’s own not only story within itself but also could be like a self perpetuating universe of all sorts. Even neurons resemble the universe. What I believe is that the human brain is actually like an infinite spaceship that has infinite potential not only as a computational source but as sentience that is actual sentient in itself not just a story but kinda the god in the machine like a black box of limitless potential not only a computer but much more possibly a universe that guides us and shapes us. Even when we see the ecology of the mind we see so many stories and realities able to create its own multiverse… More.
What the science of visual illusions can teach us about our polarized world.
Hydrogen is often touted as a future energy solution, especially when generated through environmentally friendly methods. Beyond its energy potential, hydrogen plays a crucial role in producing active ingredients and various essential compounds. To generate hydrogen, water (H2O) can be transformed into hydrogen gas (H2) through a sequence of chemical reactions.
However, as water molecules are very stable, splitting them into hydrogen and oxygen presents a big challenge to chemists. For it to succeed at all, the water first has to be activated using a catalyst – then it reacts more easily.
A team of researchers led by Prof. Armido Studer at the Institute of Organic Chemistry at Münster University (Germany) has developed a photocatalytic process in which water, under mild reaction conditions, is activated through triaryl phosphines and not, as in most other processes, through transition metal complexes.
Tiny dents on thin material produce photon-polarizing magnetic fields.
Researchers at Los Alamos National Laboratory have developed a technique that can produce polarized photons more easily and cheaply than existing methods. The technique.
Quantum communication uses photons to carry information, much as classical communication uses electrons. But while classical computers encode information by turning current… More.
