Saudi Team Receives US National Science Foundation Research Grant

The US National Science Foundation (NSF) has provided a research grant worth $1.2 million to a research team consisting of three American universities led by Saudi academic and faculty member at the University of California, Dr. Faisal Nawab.
In a statement to the Saudi Press Agency (SPA), he said that the universities participating in the research team include the University of California at Irvine, the University of California at Davis, and New Jersey Tech, noting that the project aims to address the challenges of data protection and privacy in Internet applications and smart cities.
He added that the project seeks to enable the transformation of the current data infrastructure to comply with user data protection legislation and regulations, such as the personal data protection system that the Kingdom is working on, represented by the Saudi Data and Artificial Intelligence Authority (SDAIA).
He stated that the team's mission will last four years, and its first results will be revealed at the Data Systems Development Conference in Italy and will be presented and discussed annually at the NSF.
Dr. Nawab highlighted his cooperation with some Saudi universities and entities through his research laboratory at the University of California for this goal, adding that Saudi Arabia, represented by SDAIA, was the first to introduce systems and regulations for data protection in a way that guarantees user rights and that personal data protection.

Muddy footprints left on a Kenyan lakeside suggest two of our early human ancestors were nearby neighbors some 1.5 million years ago.
The footprints were left in the mud by two different species “within a matter of hours, or at most days,” said paleontologist Louise Leakey, co-author of the research published Thursday in the journal Science.
Scientists previously knew from fossil remains that these two extinct branches of the human evolutionary tree – called Homo erectus and Paranthropus boisei – lived about the same time in the Turkana Basin.
But dating fossils is not exact. “It’s plus or minus a few thousand years,” said paleontologist William Harcourt-Smith of Lehman College and the American Museum of Natural History in New York, who was not involved in the study.
Yet with fossil footprints, “there’s an actual moment in time preserved,” he said. “It’s an amazing discovery.”
The tracks of fossil footprints were uncovered in 2021 in what is today Koobi Fora, Kenya, said Leaky, who is based at New York's Stony Brook University.
Whether the two individuals passed by the eastern side of Lake Turkana at the same time – or a day or two apart – they likely knew of each other’s existence, said study co-author Kevin Hatala, a paleoanthropologist at Chatham University in Pittsburgh.
“They probably saw each other, probably knew each other was there and probably influenced each other in some way,” The Associated Press quoted him as saying.
Scientists were able to distinguish between the two species because of the shape of the footprints, which holds clues to the anatomy of the foot and how it’s being used.
H. erectus appeared to be walking similar to how modern humans walk – striking the ground heel first, then rolling weight over the ball of the foot and toes and pushing off again.
The other species, which was also walking upright, was moving “in a different way from anything else we’ve seen before, anywhere else,” said co-author Erin Marie Williams-Hatala, a human evolutionary anatomist at Chatham.
Among other details, the footprints suggest more mobility in their big toe, compared to H. erectus or modern humans, said Hatala.
Our common primate ancestors probably had hands and feet adapted for grasping branches, but over time the feet of human ancestors evolved to enable walking upright, researchers say.
The new study adds to a growing body of research that implies this transformation to bipedalism – walking on two feet — didn’t happen at a single moment, in a single way.
Rather, there may have been a variety of ways that early humans learned to walk, run, stumble and slide on prehistoric muddy slopes.
“It turns out, there are different gait mechanics – different ways of being bipedal,” said Harcourt-Smith.
