Neolithic surgeons might have practiced their skull-drilling techniques on cows

Trepanation may not have been limited to humans.

Bovine brain surgery is pretty rare. So if you were visiting the Neolithic dig site at Champ-Durand in France and you found a roughly 5,200 year-old cow skull with a…

Evernote cuts staff as user growth stalls

Image
Note-taking app Evernote has fallen on hard times of late, culminating in its latest spate of job cuts impacting 15 percent of its workforce (54 employees). CEO Chris O' Neil -- an ex-Googler who took the reins in 2015 -- announced the firings at an all-hands meeting earlier today, reports TechCrunch . In a message on the Evernote blog , O' Neill admitted he'd set "incredibly aggressive goals" for the company in 2018. He continued: "Going forward, we are streamlining certain functions, like sales, so we can continue to speed up and scale others, like product development and engineering." The layoffs follow an exec exodus just weeks ago and the company's recent brand refresh (complete with a refined logo and wordmark). But critics are more concerned about its product, especially the free tier, which they claim lacks the perks to...

After six summers of researching, testing, and recommending window air conditioners, we've learned that quiet and affordable ACs make most people the happiest—and we think the LG LW8016ER will fit the bill in most rooms. This 8,000 Btu unit cools as efficiently and effectively as any model with an equal Btu rating, and runs at a lower volume and deeper pitch than others at this price. Little extra features like a fresh-air vent, two-axis fan blades, and a removable drain plug help set it apart, too. The LG LW8016ER is a top choice for an office or den, and some people will find it quiet enough for a bedroom, too. If our main pic...

We won't see a 'universal' vape oil cartridge anytime soon

Image
Pre-loaded cartridges of cannabis concentrate are currently among the most popular means of consumption, and for good reason. They're discreet to use and easy to handle, a far cry from the dark days of 2016 when we had to dribble hash oil or load wax into narrow-mouthed vape pens by hand. But, frustratingly, an ever increasing number of oil cartridge manufacturers employ one-off design standards so that their products won't work with those of their competitors, thereby locking customers into proprietary ecosystems. We've already seen this with nicotine vaporizers -- which has a seen a massive rise in "pod systems" in the last few years, each outfitted with a unique canister and battery built to be incompatible with those of their competition. Is it too late for the burgeoning cannabis industry to set a universal standard for their product designs? ...
