Roughly 25 percent (23.4 percent to be exact) of the Earth’s sea floor has been mapped, thanks to an international initiative known as Seabed 2030. Relying largely on voluntary contributions of bathymetric data (or ocean topography) by governments, companies and research institutions, the project is part of a larger UN-led initiative called The Ocean Decade. Seabed 2030 hopes to map 100 percent of the ocean floor by 2030, which researchers say will be possible thanks to advances in technology and corralling already available data. Over the past year alone, Seabed 2030 has added measurements for around 3.8 million square miles (roughly the size of Europe) primarily through newly opened archives, rather than active mapping efforts.

Scientists believe collecting more bathymetric data will help further our understanding of climate change and ocean preservation efforts. Ocean floor mapping also helps in the detection of tsunamis and other natural disasters. “A complete map of the ocean floor is the missing tool that will enable us to tackle some of the most pressing environmental challenges of our time, including climate change and marine pollution. It will enable us to safeguard the planet’s future,” said Mitsuyuki Unno, executive director of The Nippon Foundation in a press release. 

As the BBC notes, much of the data used in Seabed 2030 already existed. The group largely relies on contributions from governments and companies, though some of these entities are still reluctant to completely open up their archives for fear of spilling national or trade secrets. 

All the data that Seabed 2030 is collecting will be available to the public online on the GEBCO (General Bathymetric Chart of the Oceans) global grid. Prior to Seabed 2030, very little directly measured ocean floor data was available for public use. Most bathymetric measurements are estimated using satellite altimeter readings, which give a very rough idea of the shape of the sea floor surface. Some scientists believe a global effort to locate the crash of Malaysia Airlines flight MH370 would have been better informed by newer, more precise methods to chart the ocean floor.

If your Pixel is in need of some care, you can now buy official parts to try and fix the problem yourself. Parts and detailed repair guides for Pixel 2 and above are now available from iFixit.

The parts include screens, batteries, rear cameras and charging ports. They’re available à la carte and iFixit plans to offer more types of parts in the future. You can also buy Fix Kits, which iFixit says include everything that a Pixel user needs to repair their device. Each kit comes with a gizmo to open the phone and official adhesive to seal it back up. The parts have a lifetime guarantee from iFixit — save for batteries, which have a one-year guarantee.

At the outset, iFixit is selling the parts in the US, UK, Canada, Australia and other European countries where Google offers Pixels. The company also plans to support future Pixel models as soon as possible after launch. It will have guides and parts for Pixel 6a this fall, for instance. In addition, iFixit is selling parts wholesale to independent repair shops.

Google and iFixit announced a partnership in April to offer Pixel users official parts. Apple and Samsung have also committed to enabling customers to self-repair devices. The smartphone makers made those moves amid a broader push for right-to-repair rules. 

Earlier this month, the New York state assembly passed a right-to-repair bill, which is now on the governor’s desk to sign or veto. Only a few other states have passed similar legislation. The Federal Trade Commission has also taken aim at illegal repair restrictions.

Air travel remains one of the largest contributors to global warming in the transportation sector, producing 915 million tonnes of CO2 worldwide in 2019, per ATAG. In an effort to usher in a more sustainable era of flight, NASA announced Thursday that it is seeking partners “to develop technologies needed to shape a new generation of lower-emission, single-aisle airliners that passengers could see in airports in the 2030s.” 

NASA is looking to fund the design, building, testing and flying of large-scale demonstrators as part of its new Announcement for Partnership Proposals program. Specifically, the agency seeks to “reduce carbon emissions from aviation and ensure US competitiveness in a high-demand area of aircraft design — single-aisle commercial airliners.”

“In the coming years, global air mobility will continue to grow at a steady pace, and single aisle aircraft will continue to carry the majority of that passenger traffic,” Bob Pearce, NASA associate administrator for the Aeronautics Research Mission Directorate, said in Thursday’s media release. “Working with industry, NASA intends to seize this opportunity to meet our aggressive environmental goals while fostering continued global leadership of the U.S. aviation industry.”

This effort comes as part of the White House’s US Aviation Climate Action Plan, which itself aims to make make aviation emissions carbon-neutral by 2050. To help reach that deadline, NASA is planning to have these demonstrators ready by the end of the decade so that the lessons learned can be applied to the next generation of single-aisle aircraft coming in the 2030s. NASA plans to select at least one industry partner early next year, granting them funding and access to NASA facilities at Armstrong Flight Research Center in Edwards, California.
