In the unrelenting heat of the UAE desert, scientists from NYU Abu Dhabi’s Smart Materials Lab have discovered the secret of one of the plant world’s most interesting and possibly useful species — Tamarix aphylla. This unassuming desert shrub can extract water from thin air, and tears up the rulebook on survival in one of the world’s harshest environments.

Marieh Al-Handawi, a Postdoctoral Associate, and her partner, Professor Panče Naumov, have made a groundbreaking discovery about Tamarix aphylla that could revolutionize our approach to water collection in arid regions. The desert shrub’s roots absorb hyper-saline water from the sandy soil, carefully filtering away the salt and expelling it as a concentrated solution onto the outer surface of its leaves as a mixture of over ten different minerals.

The crystalized minerals on the plant’s leaves possess a remarkable ability to attract further moisture from the air, even at humidity levels of just 55%. This collected moisture condenses on the leaves’ surface and is rapidly absorbed, creating a cyclical process that can continue indefinitely.

Lead author of the research, Marieh Al-Handawi, has high hopes for the team’s findings, explaining: “They also open prospects for designing environmentally benign formulations based on a biogenic salt mixture that could be used for efficient harvesting of aerial water or cloud seeding at low humidity. This holds the promise of revolutionizing cloud seeding practices by rendering them more effective and environmentally friendly while also aligning with our responsibility to use the planet’s scarce water resources wisely”.

In a world where fresh water is becoming increasingly scarce, Al-Handawi and her team’s research could prove to be game-changing, with alternative water-harvesting technologies becoming a hot topic in the MENA region in particular.

“This is the biggest day for iPad since its introduction,” said CEO Tim Cook in a video posted to Apple’s website.

Apple’s latest updates to its popular iPad Air and Pro models were announced on Tuesday, May 7. These are the first changes since 2022, the longest stretch between new models since the iconic device was revealed in 2011.

Both the 11-inch and 12.9-inch versions of the iPad Pro have received a huge design overhaul. The most noteworthy change is the move to OLED screens, with the 12.9-inch version receiving a small bump in size to 13 inches. Apple claims the new tablets are brighter and more vibrant than outgoing models, thanks to a technology it calls “tandem OLED” or “Ultra Retina XDR”.

The 13-inch model now measures an astonishing 5.1 mm in thickness, which Apple says is its slimmest device ever. (The 11-inch version is 5.3 mm thick.) For those who prefer the look of a matte display, a nano-texture coating will also be available for the first time on the Pro models.

Finally, the new iPad Pros have received a processor bump to the latest M4 chip, which Apple says is an “outrageously powerful chip for AI”, offering an example of its ability to quickly and efficiently isolate subjects from backgrounds in videos.

The iPad Pro 11-inch starts at $999, and the larger 13-inch version starts at $1,299 with 256GB of storage.

Updated iPad Air In Two Sizes

The sixth-generation iPad Air didn’t receive as many upgrades as the iPad Pro but significantly does now come in two sizes. As with the Pro models, buyers now have the choice between an 11-inch and 13-inch screen, meaning they don’t need to invest in a Pro version just to get a 30% bump in display size.

Apple kept the same design for the iPad Air that it first revealed in 2020, complete with a USB-C port and Touch ID in the top button. The only difference is the front camera placement, which has been moved to the center of the iPad when in landscape orientation.

The 11-inch iPad Air is priced at $599 for the entry-level model, while the 13-inch version starts at $799.

New Magic Keyboard Case

Apple also announced an updated (thinner, lighter) Magic Keyboard for its Pro iPads. The refreshed version now includes a function row (with controls for screen brightness). An aluminum palm rest and large trackpad with haptic feedback also help the premium case feel more like a Macbook.

The new Magic Keyboard is available for both the 11-inch and 13-inch iPad Pros and will be priced at $299 or $349, respectively.

Apple Pencil Pro

Apple also announced a new Apple Pencil, named Pro, at its event. The new model looks exactly the same but adds a “squeeze” function that opens a new tool palette. Meanwhile, a built-in gyroscope sensor lets you alter the orientation of the tools you’re using as you twist the device, offering finer control. Finally, the new pencil gets support for Apple’s Find My network, which should keep minds at rest at the prospect of losing the $129 device.

Finally, to round off Apple’s series of announcements, the entry-level iPad was reduced to $349 — a $100 price cut.
