News: Scientists Are Using the Special Physics of Dragonfly Wings to Create Surfaces That Shred Bacteria on Contact

As drug-resistant bacteria become more commonplace, researchers are looking for new antibacterial strategies to disrupt disease-causing microbes. Some scientists are working to create new drugs, while others are trying out drug combinations. Another group, however, are ditching pharmaceuticals altogether and experimenting with non-drug alternatives.

Hacking macOS: How to Perform Situational Awareness Attacks, Part 1 (Using System Profiler & ARP)

The first few minutes after gaining access to a MacBook are critical — but where do we begin? Using tools built into macOS, we can develop an in-depth understanding of running background processes, detect antivirus software, locate sensitive files, and fingerprint other devices on the network.

IFTTT 101: How to Find & Set Up Applets

IFTTT (short for If This, Then That) is an amazing piece of software that automagically links actions on your phone with online services and real-world objects. For example, an applet could read: "if you come home, then turn on Wi-Fi." IFTTT goes further than just using simple smartphone functions, though — thanks to applets, it's fully configurable with a ton of smartphone apps.

News: Google Home Will Soon Be Able to Support Multiple Users

The "Discover" tab in the latest version of the Google Home app has a new tip that says multiple users are now supported.

One of the best things about talking to other people who love food is that they point you to weirdly beautiful ingredients, like this: No, that's not an escapee from Middle Earth you're seeing. It's one of Mother Nature's best attempts at making fractals come alive into a golden spiral: the Romanesco (sometimes called fractal broccoli, broccoflower, or Romanesque cauliflower). Here's another view: So Just What Is It & What Does It Taste Like?

How To: Explore Density, Viscosity & Miscibility with a Colorful Layered Liquid Science Experiment

Ever wonder why Jupiter has those colored bands across its surface? Jupiter's enormous mass is made from an array of different liquids, and those fluids do not play well together because of their different makeup. All of the hydrogen- and helium-based fluids are thought not to be miscible, which means that they aren't homogeneous in nature, resulting in strikingly beautiful bands across the planet's surface. But what about viscosity and how that correlates to the development of planets? What ...

In this video, doctors can learn how to perform a full cardiac examination on a patient. The very first thing a doctor should do is visually inspect the patient, because there's a lot that can be gained by simply examining by eye.

Feeling the pulse is also necessary when starting out this heart exam. To learn more, watch the full video.

How To: Check Your MacOS Computer for Malware & Keyloggers

While you might suspect your MacOS computer has been infected with malware, it can be difficult to know for sure. One way to spot malicious programs is to look for suspicious behavior — like programs listening in on our keyboard input or launching themselves every time we boot. Thanks to free MacOS tools called ReiKey and KnockKnock, we can detect suspicious programs to discover keyloggers and other persistent malware lurking on our system.

How To: Find Identifying Information from a Phone Number Using OSINT Tools

How To: Bypass an iPhone's Lock Screen in iOS 12.1 & 12.1.1 to Access Contacts

While iOS 12 is arguably the best iteration of Apple's mobile operating system yet, one major fault so far is security. On Sept. 26, Videosdebarraquito discovered a passcode bypass that gave access to contacts and photos from the lock screen. Apple has since patched that security flaw, but Videosdebarraquito has discovered a new one that affects all iPhones running iOS 12.1 and 12.1.1 beta.
