The Weibel instability is investigated using relativistic intense short laser pulses. A relativistic short laser pulse can generate a sub-relativistic high-density collisionless plasma. By irradiating double parallel planar targets with two relativistic laser pulses, sub-relativistic collisionless counterstreaming plasmas are created. Since the growth rate of the Weibel instability is proportional to the plasma density and velocity, the spatial and temporal scales of the Weibel instability can be much smaller than that from nanosecond large laser facilities. Recent theoretical and numerical studies have revealed that astrophysical collisionless shocks in sub-relativistic regimes in the absence and presence of an ambient magnetic field play essential roles in cosmic ray acceleration. With experimental verification in mind, we discuss the possible experimental models on the Weibel instability with intense short laser pulses. In order to show the experimental feasibility, we perform 2D particle-in-cell simulations in the absence of an external magnetic field as the first step and discuss the optimum conditions to realize the nonlinear evolutions of the Weibel instability in laboratories.

Russia cannot meet its arms delivery commitments to India because of its ongoing invasion of Ukraine, according to the Indian Air Force (AIF).

The statement, aired during a parliamentary committee meeting earlier this week, was the first official confirmation from New Delhi of Moscow’s defense export shortfalls.

It confirmed speculation that Russia’s defense industry is experiencing serious problems producing military supplies.

Basically we are nearing if not already in the age of infinity. What this means is that full automation can be realized imagine not needing really to work to survive bit we could thrive and work on harder things like new innovative things. Basically we could automate all work so we could automate the planet to get to year million or year infinity maybe even days or months once realized full automation could lead to more even for physics where one could finally find the theory of everything or even master algorithm. 😀 Really in the age of infinity anything could be possible from solving impossible problems to nearly anything.

Scientists at St. Jude Children’s Research Hospital and Rockefeller University have combined their expertise to gain a better understanding of the cystic fibrosis transmembrane conductance regulator (CFTR). Mutations in CFTR cause cystic fibrosis, a fatal disease with no cure.

Current therapies using a drug called a potentiator can enhance CFTR functions in some patients; but how the potentiators work is not well understood. The new findings reveal how CFTR functions mechanistically and how disease mutations and potentiators affect those functions. With this information, researchers may be able to design more effective therapies for cystic fibrosis. The study was published today in Nature.

Cystic fibrosis is a genetic disorder that causes people to produce mucus that is too thick and sticky. This can block airways and lead to lung damage as well as cause problems with digestion. The disease affects about 35,000 people in the United States. CFTR is an anion channel, a passageway that maintains the right balance of salts and fluid across epithelial and other membranes. Mutations in CFTR are what cause cystic fibrosis, but these mutations can affect CFTR function differently. Therefore, some drugs used to treat the disease can only partially restore function of specific mutant forms of CFTR.

One of the largest mysteries of science is that humans have conscious awareness of their complex subjective experiences – or what we call “qualia” – such as being aware of what it’s like to delight in the color of a flower, melt into the comfort of a bed, or to feel sharp pain. Why and how qualia could emerge from physical matter and be a part of the human experience is unknown, and this is called the ‘hard problem’ of consciousness. Related to qualia is the mystery of why humans feel like they have free will, or the ability to intentionally choose and execute actions.

The ‘easy’ problem of consciousness is mapping these mind states to brain states, such as identifying which brain regions are active during a certain experience, such as smelling a flower. Despite advances in classical physics and neuroscience, many aspects of the mind-brain relationship, such as qualia, remain unresolved. New theories of mind are required to address this perennial mystery.

In a new paper, we propose that some aspects of mind are quantum and can play an active role in the physical world, explaining some of the unexplainable.
