Coherence entropy unlocks new insights into light-field behavior

Posted by in categories: biotech/medical, internet

Light technology is at the heart of many cutting-edge innovations, from high-speed internet to advanced medical imaging. However, transmitting light through challenging environments, such as turbulent atmospheres or deformed optical systems, has always posed a significant hurdle. These complexities can distort and disrupt the light field, making it difficult to achieve clear and reliable results. Scientists have long sought ways to overcome these limitations, and a new breakthrough may hold the key to advancing practical applications.

Cricket physics: Wind tunnel experiments reveal why bowling with a near horizontal arm makes for tough batting

Posted by in category: physics

Key to winning a cricket match is tricking the other team’s batters—no small feat, as bowlers bowl cricket balls nearly 100 miles per hour. In recent years, a bowling technique that has become popular involves keeping the arm almost entirely horizontal during delivery, notably used by Sri Lankan stars Lasith Malinga and Matheesha Pathirana. The aerodynamics of such deliveries have perplexed sports physicists.

New massive eccentric brown dwarf discovered

Posted by in category: space

An international team of astronomers has reported the discovery of a new brown dwarf, which received designation TOI-2490 b. The newfound object is about 74 times more massive than Jupiter and orbits a sun-like star on a highly eccentric orbit. The finding was detailed in a paper published August 8 on the pre-print server arXiv.

Engineering Toxoplasma gondii secretion systems for intracellular delivery of multiple large therapeutic proteins to neurons

Posted by in categories: biotech/medical, engineering, neuroscience

Bracha et al.


Toxoplasma gondii culture and maintenance.

Type I RH and type II Pru and ME49 strain T. gondii were grown in HFF in high-glucose Dulbecco’s modified Eagle’s medium (DMEM) supplemented with 4 mM l-glutamine, 10% fetal bovine serum (FBS) and 1% penicillin/streptomycin or 20 μg ml−1 gentamicin antibiotics (‘complete DMEM’) at 37 °C with 5% CO2. Cultures were monitored daily and T. gondii were passaged by transferring 1–3 drops (20–100 μl) of the supernatant of a lysed dish (containing extracellular parasites) into a fresh dish with confluent HFF cells. Type I RH and type II Pru strains were validated by PCR–restriction-fragment length polymorphism (primers described in Supplementary Table 1)81 or by passage into Cre Reporter cell lines to confirm Cre recombination as previously described16.

Hackers May Have Leaked Every American’s Social Security Information

Posted by in category: cybercrime/malcode

Security experts are warning that a background check site may have been breached, resulting in the potential exposure of billions of Social Security and address records that could cover everyone in the United States.

As BleepingComputer reports, a hacking forum lit up when a user claimed to have access to a huge cache of documents gleaned from data brokerage National Public Data.

Though it doesn’t share its methodology on its website, NPD is believed to scrape its data from publicly available records to create individual user profiles generally used by private investigators or in background or criminal records checks.
