Automobile Crash Tests Are Going Digital

Computer simulations of crash tests help car companies save money and meticulously examine the intricacies of high-speed destruction.

There's a neat piece up now over at Wired about how General Motors employs computer-simulated crash tests to build safer cars. Not only is it cheaper to crash fake cars in a simulation than it is to smash real cars in a warehouse, but also the precision and various intricacies of the digital setup allow engineers an assortment of unique opportunities. For example, computer simulations allow for quick design tweaks when minor issues show up in the crash results. When every piece of plastic in a car is accounted for in a simulation, it's easy to spot weaknesses and design remedies.


Another perk is the ability for engineers to run different simulations for region-specific car designs. This saves a lot of money and frees up time and resources for other tasks. If the regulatory bar in Japan is different than it is in Australia, GM doesn't have to go to the trouble of building multiple prototypes for each market. 

This isn't to say that the traditional crash test is going to vanish anytime soon. No one is about to let GM sell a car that hasn't been tested in real-life scenarios. The takeaway here is that the company's technology has reached a point where it can run fewer physical tests without sacrificing safety. In fact, running fewer physical tests allows them to improve safety as it opens a new lens through which to examine the intricacies of high-speed destruction.

Can the keto diet help treat depression? Here’s what the science says so far

A growing body of research shows promising signs that the keto diet might be able to improve mental health.

  • The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
  • Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
  • Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.

  • It's commonly thought that the suppression of female sexuality is perpetuated by either men or women.
  • In a new study, researchers used economics games to observe how both genders treat sexually-available women.
  • The results suggests that both sexes punish female promiscuity, though for different reasons and different levels of intensity.
