Researchers at Duke University have demonstrated the first attack strategy that can fool industry-standard autonomous vehicle sensors into believing nearby objects are closer (or further) than they appear without being detected.

The research suggests that adding optical 3D capabilities or the ability to share data with nearby cars may be necessary to fully protect from attacks.

The results will be presented Aug. 10–12 at the 2022 USENIX Security Symposium, a top venue in the field.

The plan is there is no plan.


So it turns out we may be America’s worst-designed city. Lack of “official” zoning. Messy roads and meager public transportation options. Complete chaos. We get it, our predecessors sucked at design. But that may not necessarily be a bad thing. In fact, there are a bunch of ways in which the city totally (and unintentionally) came out ahead in the whole “the plan is there is no plan” deal.

Love it or hate it, Houston’s lack of zoning may actually be what shielded it from the popped housing bubble that rocked the rest of the country. Picture Margot Robbie explaining this all whilst in a bubble bath drinking champagne. While housing prices soared as the national bubble inflated, Houston’s costs remained modest; and when all hell broke loose when the bubble burst, H-town remained largely unaffected.

As discussed in an article from the Chron, senior economist Bill Gilmer found that zoning regulations were partly to blame. First, the laws constricted supply, which resulted in raising the cost of new home construction. As housing demand increased, cities with strict zoning laws saw prices increase due to the lack of supply. In turn, the high housing prices extinguished demand and — BOOM — the mortgage market collapsed and chaos consumed the majority of the country — minus Houston, where the increase in demand was met with an increase in construction/supply. Or something like that. Whatever. Margot Robbie in a bubble bath.

Dubbed Infinity Train, it works by using gravitational energy created on the downhill sections of the rail network to recharge its battery power and eliminate the need for recharging on the return leg of the journey.

The train will allow for a capital-efficient solution for removing diesel and pollutants from Fortescue’s rail operations. It will also help remove the need for the generation of renewable energy as well as the setting up of expensive charging infrastructure.

Researchers at Johns Hopkins University have developed a new shock-absorbing material that is super lightweight, yet offers the protection of metal. The stuff could make for helmets, armor and vehicle parts that are lighter, stronger and, importantly, reusable.

The key to the new material is what are known as liquid crystal elastomers (LCEs). These are networks of elastic polymers in a liquid crystalline phase that give them a useful combination of elasticity and stability. LCEs are normally used to make actuators and artificial muscles for robotics, but for the new study the researchers investigated the material’s ability to absorb energy.

The team created materials that consisted of tilted beams of LCE, sandwiched between stiff supporting structures. This basic unit was repeated over the material in multiple layers, so that they would buckle at different rates on impact, dissipating the energy effectively.

Engineering projects need goals, and James Worden ’89 set an especially engaging and enduring one for himself as a high school student in the early 1980s while pursuing his passion for homebuilt go-karts.
