In a study published in Device (“Self-powered electrostatic tweezer for adaptive object manipulation”), a research team led by Dr. DU Xuemin from the Shenzhen Institute of Advanced Technology (SIAT) of the Chinese Academy of Sciences has reported a new self-powered electrostatic tweezer that offers superior accumulation and tunability of triboelectric charges, enabling unprecedented flexibility and adaptability for manipulating objects in various working scenarios.

The ability to manipulate objects using physical tweezers is essential in fields such as physics, chemistry, and biology. However, conventional tweezers often require complex electrode arrays and external power sources, have limited charge-generation capabilities, or produce undesirable temperature rises.

The newly proposed self-powered electrostatic tweezer (SET) features a polyvinylidene fluoride trifluoroethylene (P(VDF-TrFE))-based self-powered electrode (SE) that generates large and tunable surface charge density through the triboelectric effect, along with a dielectric substrate that functions as both a tribo-counter material and a supportive platform, and a slippery surface to reduce resistance and biofouling during object manipulation.

Recent advancements in tachyon theory have addressed past inconsistencies by incorporating both past and future states into the boundary conditions, leading to a new quantum entanglement theory and suggesting a critical role for tachyons in matter formation.

Tachyons are hypothetical particles that travel at speeds greater than the speed of light. These superluminal particles, are the “enfant terrible” of modern physics. Until recently, they were generally regarded as entities that did not fit into the special theory of relativity. However, a paper just published by physicists from the University of Warsaw and the University of Oxford has shown that many of these prejudices were unfounded. Tachyons are not only not ruled out by the theory, but allow us to understand its causal structure better.

Superluminal Motion and Tachyons.

Australian businesses are paying untold amounts of ransom to hackers, but the government is hoping to claw back some visibility with a landmark cybersecurity law.

While major ransomware attacks on companies such as MediSecure, Optus and Latitude have grabbed headlines for breaching the privacy of millions, the practice of quietly paying off cybercriminals has flourished in the dark.

The situation has deteriorated to the point that the government’s original ambition for an outright ban on ransom payments has been nixed, for now, and the focus has shifted to mapping the scale of the problem.

A team of researchers reveals the cellular pathology of “dry” age-related macular degeneration (AMD); discovering the potential source of dysfunction in the process whereby cells in the retina remove waste.

What

The team from NIH and Johns Hopkins University, Baltimore, reported the details of how alterations in a factor called AKT2 affect the function of lysosome organelles, and results in the production of drusen deposits in the retina, which is a hallmark sign of dry age-related macular degeneration. The researchers suggest that the findings of drusen formation are a downstream effect of AKT2-related lysosome dysfunction and could point to a new target for therapeutic intervention.

“Kepler contributed many historical benchmarks in astronomy and physics in the 17th century, leaving his legacy even in the space age,” said Hisashi Hayakawa.

How can 400-year-old sunspot drawings help modern-day scientists with solar cycles? This is what a recent study published in The Astrophysical Journal Letters hopes to address as an international team of researchers used 400-year-old drawings of sunspots to better understand solar cycles and how we can study them in the future. This study holds the potential to help researchers use non-electronic scientific tools to gain greater insight into scientific discoveries around the world.

For the study, the researchers examined drawings of sunspots made by Johannes Kepler in 1,607 along with past notes to ascertain which solar cycle these sunspots belonged to, which could help astronomers piece together solar cycles during that time and predict them, as well.
