The emergence and spread of new forms of resistance remains a concern that urgently demand new antibiotics. Transcription is a vital process in bacterial cell, where genetic information in DNA is transcribed to RNA for the translation of proteins that perform cellular function. Hence, transcription serves as a promising target to develop new antibiotics because inhibition the transcription process should effectively kill the bacteria. Bacterial RNA Polymerase, the core enzyme for transcription, must load the DNA and separate the double-stranded DNA to single stranded DNA to read the genetic information to initiate transcription. This process is also called DNA melting and is facilitated by the opening and c
DUBAI: Aalya Albeeshi, a speech and hearing sciences graduate of King Saud University, is on a mission to help people with auditory disabilities express themselves through technological innovation a contribution she may not have made were it not for the Qimam Fellowship.
Now in its fourth year, the highly sought-after scheme selects just 50 students through a rigorous evaluation process from an annual pool of more than 15,000 applicants to participate in an intensive 12-day program.
Fellows are offered one-on-one mentorship from senior public- and private-sector leaders, leadership training by industry experts and professionals, and visits to the Saudi offices of top national and international companies.
Aromaticity is Inspiring New Developments in the Area of Catalysis
Written by AZoMMay 3 2021
Scientists from King Abdullah University of Science and Technology (KAUST) have demonstrated a concept known as aromaticity that is often used to describe the unusual reactivity and excellent stability of some carbon-based molecules.
An unusual family of catalysts developed at KAUST shows high catalytic performance for certain reactions, such as selective hydrogen production from formic acid. Image Credit: Reproduced from Gonçalves et al. (2021) with permission from the Royal Society of Chemistry. Original artwork Heno Hwang.
This concept could lead to the design of new catalysts with novel applications. At first, in the 19th century, chemists discovered the anomalous behavior of aromatic molecules while analyzing benzene. The unpredicted stability of this six-carbon cyclic structure is mainly due to its electrons.

During his interview with Saudi journalist Abdullah Al-Mudaifer that was broadcast last week, Crown Prince Mohammed bin Salman said: “When we commit ourselves to a certain school or scholar, this means that we are deifying human beings. God Almighty did not put a barrier between Himself and people. He revealed the Qur’an and the Prophet (peace be upon him) implemented it and the space for interpretation is open permanently.”
These words define the crown prince’s view toward the concept of moderation and the religious discourse he wants to establish a discourse based on “sectarian pluralism” and respect for diverse Islamic communities.
Renewable Feed, New Technology and C2C Strategies Offer Opportunities for Refiners
The TBEC series has been added to this company’s range…

After a rough past year, petroleum refineries are seeking profit opportunities through the use of renewable feedstocks, such as vegetable oils and waste fats, as well as with new alkylation technologies and by increasing “crude-to-chemicals” (C2C) approaches
The past 18 months have generally been extraordinarily challenging for the world’s petroleum refineries, as pandemic-related restrictions dramatically reduced demand for refinery products and cut refinery utilization rates. Even with demand for transportation fuels returning as the world economy begins to emerge from the pandemic, long-term growth in gasoline and diesel fuel demand is not expected. Flat fuel demand growth, coupled with a broader trend toward decarbonizing the energy sector and increasing investment tied to environmental, social an
