Astrophysicists find evidence that Alfvén waves lead to heat generation in the magnetosphere

Posted by in categories: particle physics, space

In the vast reaches of space, invisible forces shape the behavior of charged particles in ways that are only now beginning to be fully understood.


A small team of astrophysicists at the University of California, Los Angeles, working with colleagues from the University of Texas at Dallas and the University of Colorado, Boulder, has found evidence that Alfvén waves in space plasmas speed up ion beams, resulting in the creation of small-scale acoustic waves that in turn generate heat in the magnetosphere.

In their study, published in the journal Physical Review Letters, the group used data from the four-spacecraft Magnetospheric Multiscale (MMS) mission that took place in 2015 to prove a about heat generation in the .

Nanopesticide delivery system made with neem seed extract improves pesticide effectiveness

Posted by in categories: chemistry, engineering, food, sustainability

Pesticides can be made more effective and environmentally friendly by improving how they stick to plant surfaces, thanks to new research led by Dr. Mustafa Akbulut, professor of chemical engineering at Texas A&M University.

Akbulut and his research group have developed an innovative pesticide delivery system called nanopesticides. These tiny technologies, developed through a collaboration between Texas A&M University’s engineering and agricultural colleges, Dr. Luis Cisneros-Zevallo, professor of Horticultural Science and Dr. Younjin Min, professor of Chemical Environ Engineering at University of California, Riverside, could change how we use pesticides.

“The U.S. is a world leader in , feeding not just our nation but much of the world. Yet we are using pesticides in a way that is simply not sustainable—with a substantial fraction not reaching its intended target,” said Akbulut. “Our research shows that by optimizing the surface chemistry of pesticide carriers, we can make these essential crop protection tools more efficient.”

Integrated Information Theory of Consciousness

Posted by in categories: computing, neuroscience

Integrated Information Theory (IIT) offers an explanation for the nature and source of consciousness. Initially proposed by Giulio Tononi in 2004, it claims that consciousness is identical to a certain kind of information, the realization of which requires physical, not merely functional, integration, and which can be measured mathematically according to the phi metric.

The theory attempts a balance between two different sets of convictions. On the one hand, it strives to preserve the Cartesian intuitions that experience is immediate, direct, and unified. This, according to IIT’s proponents and its methodology, rules out accounts of consciousness such as functionalism that explain experience as a system operating in a certain way, as well as ruling out any eliminativist theories that deny the existence of consciousness. On the other hand, IIT takes neuroscientific descriptions of the brain as a starting point for understanding what must be true of a physical system in order for it to be conscious. (Most of IIT’s developers and main proponents are neuroscientists.) IIT’s methodology involves characterizing the fundamentally subjective nature of consciousness and positing the physical attributes necessary for a system to realize it.

In short, according to IIT, consciousness requires a grouping of elements within a system that have physical cause-effect power upon one another. This in turn implies that only reentrant architecture consisting of feedback loops, whether neural or computational, will realize consciousness. Such groupings make a difference to themselves, not just to outside observers. This constitutes integrated information. Of the various groupings within a system that possess such causal power, one will do so maximally. This local maximum of integrated information is identical to consciousness.

Pushing the limits of artificial enzymes

Posted by in categories: biotech/medical, chemistry

Researchers from CSIR-Central Leather Research Institute (CLRI), supported by INSPIRE Faculty and WISE Kiran Fellowships, explored the chemistry between proteins and nanozymes to advance artificial enzymes. Their work focuses on using manganese-based oxidase nanozyme (MnN) to crosslink collagen, a key structural protein, aiming to develop biomaterials for future medicinal and biomedical applications.
