The researchers claim it’s the first “complete” embryo model for simulating all the important components that form in the early embryo.
The science of baby-making is clear. A sperm cell (which contains genetic material from the father) and an egg cell (which contains genetic material from the mother) must fuse in order for a human embryo to develop.
However, science and technology are constantly improving in the fields of embryology and stem cell research.
The team plans to build battery-free underwater networks.
Deep Sea exploration is about to get more accessible. Researchers at the Massachusetts Institute of Technology (MIT) have developed and demonstrated a technology that can transmit underwater signals spanning kilometers with a relatively low reader transmit power.
The researchers are calling their tech Van Atta Acoustic Backscatter (VAB), which can be used to map the pulse of the ocean. A submerged network of underwater sensors can continuously measure ocean vital signs like the temperature, pressure, and dissolved carbon dioxide to create more accurate climate change models and monitor the efficacy of carbon capture technologies, explained the researchers in their study.
Year 2022 Infinite quantum computer :3.
The scaling of the entanglement entropy at a quantum critical point allows us to extract universal properties of the state, e.g., the central charge of a conformal field theory. With the rapid improvement of noisy intermediate-scale quantum (NISQ) devices, these quantum computers present themselves as a powerful tool to study critical many-body systems. We use finite-depth quantum circuits suitable for NISQ devices as a variational ansatz to represent ground states of critical, infinite systems. We find universal finite-depth scaling relations for these circuits and verify them numerically at two different critical points, i.e., the critical Ising model with an additional symmetry-preserving term and the critical XXZ model.
For years, researchers have tried various ways to coax quantum bits—or qubits, the basic building blocks of quantum computers—to remain in their quantum state for ever-longer times, a key step in creating devices like quantum sensors, gyroscopes, and memories.
A team of physicists from MIT have taken an important step forward in that quest, and to do it, they borrowed a concept from an unlikely source—noise-cancelling headphones.
Led by Ju Li, the Battelle Energy Alliance Professor in Nuclear Engineering and professor of materials science and engineering, and Paola Cappellaro, the Ford Professor of Engineering in the Department of Nuclear Science and Engineering and Research Laboratory of Electronics, and a professor of physics, the team described a method to achieve a 20-fold increase in the coherence times for nuclear-spin qubits.
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.
