GPS-tracking, 3D-printed decoy eggs can help root out illegal poachers

Poachers pose a major threat to sea turtle nests by stealing eggs to sell in what has become a rampant black market trade in certain parts of the world. Conservation efforts to stop this have, to date, included patrolling beaches for would-be poachers, as well as removing the eggs and placing them in a secure hatchery so that they can be incubated in safety.

Conservationists at the nonprofit organization Paso Pacifico in Nicaragua and researchers from the U.K.’s University of Kent have another idea, however — and it involves 3D-printed decoy eggs, boasting built-in GPS trackers.

While that might sound an unnecessarily over-engineered solution to the problem, in fact, it could help to change the calculus with which this kind of egg poaching is addressed by making it a more proactive, less reactive, solution.

“If we can be proactive we’ve got a bigger chance of dealing with the problem,” Helen Pheasey, a Ph.D. student in Conservation Biology at the University of Kent, told Digital Trends. “If people are actually trafficking the eggs inland, then that’s something that we can really start to look at [solving in a more permanent way.] That’s a bigger crime in a lot of respects, and that’s what we’re trying to address with these decoys.”

Like Find My iPhone for poachers

The decoy eggs are called InvestEggator (the name might be amusingly groan-worthy, but it’s most definitely all in a good cause.) Working a bit like a Find My iPhone tracker to fight poachers, the idea is that law enforcement would be able to track where the eggs are taken to, and this data could then be admissible in court.

In a recent proof-of-concept test case, Pheasey and her team deployed the “eggs” by walking beaches and placing them within the vicinity of a laying turtle. “Turtles lay about 100 to 120 eggs depending on the species, so it’s quite easy to sneak one of these decoys in with the eggs [without them being noticed,]” Pheasey said.

A quarter of the fake eggs they deployed were taken, and they were able to track these using location signals that were sent each hour. While most remained in the local area, one was taken further afield and helped to identify a trade chain.

In the future, Pheasey said similar technology could help other hunted species as well. “As the technology gets smaller, and more innovations become available to us, we can start putting [similar technology] in housing that would be appropriate for other species — for example, parrot eggs or shark fins,” she said. “The limitations aren’t so much the technology anymore as they are the housing and deployment. [Going forward, we believe that] there are lots of opportunities for this kind of project.”

A paper describing the work was recently published in the journal Current Biology.

Qualcomm’s long-awaited second-gen 3D Sonic fingerprint sensor is 50% faster
qualcomm 3d sonic sensor second generation ces 2021 2nd gen

Qualcomm wants to make its in-display fingerprint sensor a little bit more seamless. Its first-generation Sonic Sensor was introduced a few years ago, and at the time offered a decent experience -- but since then, has been overtaken in terms of speed and performance by competing optical sensors. Now, Qualcomm has finally launched a new, second-generation 3D Sonic sensor with big improvements.

The new sensor is 77% larger than Qualcomm's original 3D Sonic Sensor, measuring in at 8mm square, compared to the original's 4mm by 9mm. In other words, you'll be able to place your finger on a larger portion of the screen, making the overall experience a little more seamless.

Wild new 3D printer makes parts by sending titanium particles supersonic
3D printing metal technique

Regular layer-by-layer 3D printing is old news compared to a new additive manufacturing technique developed by an international team of engineers. They recently demonstrated an innovative method for printing 3D metal objects by firing a powder that’s composed of tiny titanium particles, at supersonic speed, so that they fuse together in any interesting way.

This “cold spray” approach takes place below the melting temperature of the metal. When the particles hit the substrate at high enough velocity, they deform and adhere to it. The efficiency of this adhesion increases as the particle velocity increases. Without the high-speed impact, metal powders would simply not adhere well.
