Looking up the sky: UFOs and economic attention

A new study by Dr. Ohad Raveh and Dr. Nathan Goldstein finds that UAP sightings are positively correlated with economic conditions across regions but display counter-cyclical patterns within those regions over time. The research suggests that shifts in attention to extraordinary phenomena may reflect broader fluctuations in public focus.

The West is best to spot UFOs

A new study analyzed 98,000 UAP sighting reports over a 20-year period, finding that the majority occurred in western parts of the US. The researchers identified 'hot spots' with high numbers of reports and 'cold spots' with low numbers.

SAMSUNG T9 Portable SSD 2TB transfers large imagery and model outputs quickly between field laptops, lab workstations, and secure archives.

Storytelling bots learn to punch up their last lines

Researchers at Carnegie Mellon University developed a model for generating story endings that are both relevant and diverse. The algorithm incorporates key words from the early part of the story and rewards rare word usage to create interesting endings.

How UFOs can improve sweet cherry production

Planting angle, cordon height, and bud selection significantly impact canopy establishment in UFO trees. Effective practices can increase grower success and reduce crop load potential, optimizing labor efficiency and uniformity.

Mutual mistrust may have added a few X-files to the UFO era

A Penn State historian explores how mutual mistrust fueled the UFO movement, which shares similarities with current denialism and conspiracy theory debates. The study finds that ufologists' distrust of scientists is a key factor in understanding the phenomenon.

When a 'UFO' flies by, does it bother bears?

Researchers found that bears' heart rates increase significantly when exposed to unmanned aerial vehicles, a sign of acute stress. Despite the calm behavior observed in encounters with UAVs, the physiological response is notable, with one bear's heart rate increasing by up to 400 percent.

UFO cross-section gives snakes a lift

Researchers used a 3D printer to recreate the snake's UFO-like cross-section and found that it generates sufficient lift at most angles. However, they also discovered a massive spike in lift when tilting the model at 35 degrees and an unexpected vortex sucking the rod down.
