Unveiling new insights through ancient DNA

KAUST ·

Hanin Ahmed, a KAUST Ph.D. graduate in plant science, is now an Ibn-Rushd Postdoctoral Fellow at The Centre for Anthropology and Genomics of Toulouse, France. Her Ph.D. research at KAUST focused on the population genomics and evolutionary history of fonio millet and einkorn wheat. One key finding was the influence of ethnic groups on the genetic diversity of fonio millet, and insights into wheat adaptation during early agriculture from einkorn wheat research published in Nature. Why it matters: This highlights KAUST's role in training researchers who are contributing to advancements in genomics and agriculture, with implications for crop improvement and understanding the impact of social factors on plant genetics.

From Neanderthal to Google

KAUST ·

Janet Kelso from the Max Planck Institute and Sudhir Kumar from Temple University discussed evolutionary biology in a KAUST Facebook Live interview. Kelso's research focuses on interactions between modern humans and Neanderthals, finding similarities in DNA and benefits for environmental adaptation. Kumar's work, highly cited, involves big data analyses in evolutionary biology. Why it matters: The interview highlights KAUST's engagement with international experts in bioinformatics and evolutionary biology, promoting interdisciplinary research and knowledge dissemination.

Reef corals have endured since the 'age of dinosaurs' and may survive global warming

KAUST ·

KAUST researchers have found that the symbiotic relationship between corals and micro-algae is 100 million years older than previously thought, dating back 160 million years. The study suggests that corals have endured numerous climate change events due to their biological characteristics. Researchers developed an updated naming scheme using genetic techniques to identify different micro-algal symbionts. Why it matters: This discovery offers a glimmer of hope for coral survival in the face of modern global warming and enhances conservation efforts, while also modernizing coral symbiont taxonomy.

Genetic secrets of rice pave way for future farming and conservation

KAUST ·

KAUST researchers have published a study in Nature Genetics detailing genomic analysis of wild rice relatives. The study examined nine tetraploid and two diploid wild relatives of rice, finding significant genetic diversity due to transposable elements. This diversity includes genes that confer resilience to heat, drought, and salinity. Why it matters: These findings can help improve rice yields, introduce rice cultivation to currently untenable regions, and protect rice crops against climate change, especially in the Middle East.

Utilizing artificial intelligence to uncover the Kingdom’s ancient stone structures

KAUST ·

KAUST researchers are using AI to analyze satellite imagery for the automated detection of ancient stone structures in northwest Saudi Arabia, including mustatils (rectangular structures dating to the late 6th millennium BCE) and ruins in circular and triangular shapes. They developed a deep learning algorithm trained on manually identified datasets to isolate similar features over a wide area. The tool converts detected pixels into geodetic coordinates using GPS, assembling them into an online map and database. Why it matters: This project exemplifies computational archaeology, speeding up archaeological discoveries, promoting cultural heritage, and providing a methodology useful to other sectors of the economy.

DNA replication under the microscope

KAUST ·

KAUST researchers used cryogenic electron microscopy (cryo-EM) to study the 3D structure of protein complexes involved in DNA replication and repair. They investigated the interaction between the Y-family TLS polymerase Pol K and mono-ubiquitylated PCNA. The study revealed that DNA binding is required for Pol K to form a rigid, active complex with PCNA. Why it matters: Understanding these structural interactions may provide insights into cancer development and drug resistance mechanisms.

A vision in color

KAUST ·

Shozo Yokoyama, a biology professor at Emory University specializing in color vision evolution, was interviewed by KAUST. Yokoyama's lab identified amino acids regulating red-green and UV vision in vertebrates. He emphasizes the importance of young scientists developing fresh perspectives on evolution and learning directly from animals. Why it matters: While not directly an AI story, the piece highlights KAUST's broader research focus and its investment in attracting and showcasing international scientific expertise, relevant to building a strong research ecosystem.

Rock art shows earliest known humans returned to Arabia after the last Ice Age

KAUST ·

A Heritage Commission and KAUST collaboration published in Nature Communications reveals the discovery of large-scale rock art panels in the Nefud Desert, dating back 12,000 years. Over 60 panels with 176 engravings were found depicting animals like camels and ibex. Paleoenvironmental analysis indicates surface water was present 14,000 years ago, supporting early human and wildlife expansion. Why it matters: The findings revise the timeline of human repopulation in Saudi Arabia's interior deserts after the Last Glacial Maximum and demonstrate the significance of interdisciplinary research in understanding the region's climate history.
