| Lifecycle of the Screwworm |
From Construction Physics:
The Fall and Rise of Screwworm by Brian PotterOn June 3 of this year, a flesh-eating parasite, the screwworm, was found in a three-week-old calf near the Texas town of La Pryor. Since then, dozens more cases have been discovered in Texas and New Mexico. Outside of a screwworm outbreak in the Florida Keys in 2016 (which was contained), this marks the first screwworm infestation in the US since the 1980s.
Until now, the US has been free of screwworm not due to luck, but because of a decades-long program to eradicate the parasite by breeding it out of existence. By dropping millions of sterile male screwworm flies in an infested area, agricultural agencies can overwhelm the native, fertile male screwworms. Female screwworm flies, who only mate once in their life, will mostly mate with sterile males, producing no living offspring. Drop sterile flies for long enough, and eventually there will be no viable offspring at all, and the pest will be eliminated.
Over the course of several decades, this “sterile male technique” was used by the USDA to eliminate screwworm from the US, Mexico, and Central America. Since the early 2000s a joint US-Panamanian organization, COPEG, has maintained a “screwworm barrier” at the Darien Gap between Colombia and Panama. Every week, millions of sterile male screwworm flies are dropped over the gap, preventing the screwworms from spreading north from South America (where it remains endemic).
Sometime around 2023, the barrier at Panama failed, and for the last several years screwworm has been marching north. It’s now reached the US. Efforts are underway to eliminate screwworm from North and Central America once again, but it will likely be years before they succeed.
The screwworm eradication program was so effective at eliminating the parasite that we’ve collectively forgotten what an enormous problem it used to be. It’s worth understanding the costs inflicted by screwworm prior to its elimination, how a program emerged for eliminating it, and how control was allowed to lapse.

Russian arms giant showcases pioneering anti-drone rounds
The multiple-projectile munitions have already been delivered for army trials
A pioneering Russian anti-drone round, which uses special three-element bullets in standard small-arms munitions, has been showcased in a new video released by the defense conglomerate Rostec.
The Mnogotochie (Ellipsis) project was unveiled earlier this year and is currently undergoing trials in the army, according to the report. On Friday, Rostec published footage showing the new munitions in action at a testing range.
Mnogotochie is a variant of a multiple-projectile cartridge for rifled weapons. Each bullet consists of three stacked elements made from a special bronze-like alloy. The spin gives them sufficient stability to be compatible with muzzle brakes, unlike shotgun rounds, while the spread increases the chances of hitting and disabling a small FPV drone.
According to the developer, a Russian producer of precision firearms with expertise in specialized munitions, a 5.45x39mm Mnogotochie round remains effective at ranges of up to 150 meters, while its larger 7.62x54mm version is suited for twice that distance.
In the video, rounds of both calibers were tested in single shots and bursts against stationary and moving targets, demonstrating high penetration and a decent rate of dispersion. At 100 meters, Mnogotochie munitions have enough punch to consistently pierce a 25mm layer of wood backed by a 0.8mm steel sheet.
The idea behind the round is to remove the need for a separate anti-drone weapon, replacing it with relatively lightweight magazines for weapons already carried by troops.
The bullets were designed to be fitted on regular production lines. While series manufacturing has already been launched, the munition is considered still in development and is likely to receive upgrades.
0.8 mm is like 22 gauge sheet metal. I suspect these are not going to be particularly effective. I think you probably want something alike a CRAM, but firing 22s instead of 20 mm. Can RADAR detect a small drone accurately enough to properly aim a gun?
