Since the first sighting of the first-discovered and largest asteroid in our solar system was made in 1801 by Giuseppe Piazzi, astronomers and planetary scientists have pondered the make-up of this asteroid/dwarf planet. Its heavily battered and dimp.....»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
How to lock and hide iPhone apps in iOS 18
iOS 18 allows you to lock and hide apps to protect the information within them by requiring Face ID, Touch ID, or your passcode for access, while also concealing the content from searches, notifications, and various areas throughout the system. If so.....»»
CUPS vulnerabilities affecting Linux, Unix systems can lead to RCE
After much hyping and following prematurely leaked information by a third party, security researcher Simone Margaritelli has released details about four zero-day vulnerabilities in the Common UNIX Printing System (CUPS) that can be abused by remote,.....»»
From branches to loops: The physics of transport networks in nature
An international team of researchers described how loops, crucial for the stability of such networks, occur in transport networks found in nature. The researchers observed that when one branch of the network reaches the system's boundary, the interac.....»»

Bacterial "flipping" allows genes to assume different forms
Imagine being one cartwheel away from changing your appearance. One flip, and your brunette locks are platinum blond. That's not too far from what happens in some prokaryotes, or single-cell organisms, such as bacteria, that undergo something called.....»»
Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics
In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of ele.....»»
