A team of US engineers has built a new kind of airplane wing assembled from hundreds of tiny identical pieces and can change shape to control the plane's flight.

According to the researchers, the innovation could provide a significant boost in aircraft production, flight and maintenance efficiency.

The new approach to wing construction, designed by engineers from the NASA and MIT institute, could afford greater flexibility in the design and manufacturing of future aircraft. The new wing design was tested in a NASA wind tunnel.

The Phys.org website reported that instead of requiring separate movable surfaces such as ailerons to control the roll and pitch of the plane, as conventional wings do, the new assembly system makes it possible to deform the whole wing, or parts of it, by incorporating a mix of stiff and flexible components in its structure.

The researchers explained that the result is a wing that is much lighter, and thus much more energy efficient, than those with conventional designs, whether made from metal or composites, because the structure, comprising thousands of tiny triangles of matchstick-like struts, is composed mostly of empty space.

In a related context, the world's largest aircraft flew over the Mojave Desert in California. Made of carbon composites, this new airplane was produced by Stratolaunch Systems as it entered the private space market.

Stratolaunch was founded by Paul Allen, the late co-founder of Microsoft. The white aircraft took off and remained in the sky for over two hours before landing safely at the Mojave airport.

Japan’s Anti-Monopoly Watchdog Accuses Google of Violations in Smartphones

Japanese regulators on Tuesday accused US tech giant Google of violating anti-monopoly laws, echoing similar moves in the US and Europe.

Google Japan said in a statement that it found the action “regrettable.” It said it has invested in Japan significantly to promote innovation as a technology leader.

The Japan Fair Trade Commission’s “cease and desist order” says Google must stop the pre-installation of the Google search engine in Android smartphones, which it said in effect shuts out competition.

It’s unclear if Google, a subsidiary of Alphabet Inc., based in Mountain View in the Silicon Valley, will take legal action to fight the order.

In the US, a judge ruled last year that Google’s ubiquitous search engine illegally exploited its dominance to squash competition. Google has denied the allegations, arguing that it’s immensely popular because people like what it offers. The appeals process is likely to take years.

Japanese regulators began their investigation into Google in 2023. They said they consulted with overseas authorities dealing with similar cases.

European regulators have also slammed what they see as Google’s monopolistic dominance.

Tuesday’s move marks the first time the Japan Fair Trade Commission has taken such an action against a major global technology company.
