PrivacyScan for Mac

Spy on your own thoughts with Glass Brain

What do you get when you combine a neuroscientist with the guy who helped invent the virtual world Second Life? A way to virtually fly around the brain with a gamepad watching thoughts in real time.

That's what attendees at Austin's South By Southwest were recently treated to when Philip Rosedale, creator of Second Life, and Adam Gazzaley, a neuroscientist at the University of California San Francisco, unveiled their Glass Brain project. Onlookers were able to be neuro-voyeurs as they peeked in on the mind workings of Rosedale's wife Yvette, and watched the storm of activity taking place there. … Read more

Watch a virus-like particle try to enter a cell -- in 3D

It's one thing when a nature videographer captures a fast-moving creature in the wild and has to put up with the background images being blurry while the focus stays fixed on the object of interest. It's quite another when scientists are trying to sneak a peek at a virus as it interacts with the surface of a cell and want to focus on the virus and the cell simultaneously.

Now researchers at Princeton University say they've captured unprecedented 3D footage of a virus-like particle as it appears to try to enter a cell. To keep everything in … Read more

PaperAct Scan review

PaperAct Scan lets you take photos of important documents, turn those photos into documents, store them, and share them as needed. No matter where you are, you can quickly make a copy of anything you need with this app, and you can include it in an e-mail, either as a link or as an attached PDF.

How to give an albino alligator a CT scan

Mr. Bones has an arthritis-related jaw condition. He can't open his mouth as fully as an alligator normally can. Lately, he's not even been able to open it as wide as usual. To find out what's up, the St. Augustine Alligator Farm Zoological Park in Florida had to take him in for a CT scan.

Mr. Bones is a large albino alligator. You can't exactly sit him down and explain in English why he needs to keep still for his own good to have a successful CT scan. He had to be fully restrained, but without the use of sedatives, since administering drugs can be a risky endeavor with potentially dangerous side effects for alligators.… Read more

PaperScan review

PaperScan is an intuitive app that lets you use your iOS device's camera to create quality scans. If you're someone who always has little scraps of paper floating around (and getting lost), PaperScan is an excellent way to get organized and reduce clutter.

PaperScan opens with a tutorial that walks you through each of its steps, but even without this the app would be easy to figure out. Just aim your device at the document you want to capture, take the photo, and PaperScan will automatically crop the image, removing the background entirely, and save it as a … Read more

New ultrasound tech could improve cancer detection

Ultrasound as an imaging technique has several things going for it. For one, it's more affordable than CT and MRI scans, and it's portable, so it can easily travel to rural and low-infrastructure areas or patients who are house-bound. And unlike with CT scans and X-rays, there is no ionizing radiation exposure, hence its widespread use imaging fetuses in pregnant women.

Unfortunately, the high-frequency soundwave approach to viewing soft tissue doesn't provide great resolution, so despite all its perks, it's not the go-to imaging tech for cancer detection. Now, thanks to a new discovery out of … Read more

Scientists inch closer to blood test for pancreatic cancer

Pancreatic cancer carries one of the worst prognoses of any disease, period. A whopping 99 percent of people diagnosed with stage IV pancreatic cancer are dead within five years, and without any screening tests, it's usually found late. Even though it's one of the least diagnosed types of cancer in the US, it is the fourth-leading cause of cancer deaths. With such a grim record, scientists are hard at work looking for a test that can spot the disease earlier.

And while they caution that their work is preliminary, Danish scientists are reporting Wednesday in the Journal of the American Medical AssociationRead more
