See a flying, walking bipedal robot tackle a slackline and skateboard

Don’t let this feed into your unfounded fears of some silly robot apocalypse.

It’s a good thing we’re not living in some sci-fi dystopia where sentient robots are out to get us. Instead, let’s focus on the very real accomplishments of Leonardo, a bipedal robot with a unique way of getting around.

Leonardo stands for «LEgs ONboARD drOne,» but you can call it LEO for short. LEO is the creation of Caltech researchers, who were inspired in part by how birds can flap their wings and also hop and walk with their legs. The robot is able to pull off tricky moves like walking on a slackline and riding a skateboard.

«LEO is the first robot that uses multi-joint legs and propeller-based thrusters to achieve a fine degree of control over its balance,» Caltech said in a statement on Wednesday. The university shared a video where LEO shows off how it blurs the lines between human-like robots and drones.

The Caltech team published a paper on the robot today in the journal Science Robotics. LEO’s versatility means it can call on its walking skills, its flying ability or a combination of the two depending on the terrain and its goals. Caltech described LEO as having «uncanny balance.»

After seeing videos of Boston Dynamics harassing their own robot creations, you might wonder how LEO would respond. «Because of its propellers, you can poke or prod LEO with a lot of force without actually knocking the robot over,» said Elena-Sorina Lupu, a co-author of the paper.

The researcher are already eyeing ways to make LEO more energy efficient by upgrading the leg design to rely less on the propellers for balance while walking. The team is also working on making it more autonomous so it can assess its environment and decide how best to navigate it.

The robotics team sees a possible future for this technology on Mars, where it could represent a new generation of rotorcraft. The concept would build on the success of NASA’s Ingenuity helicopter. Imagine Ingenuity with legs, able to land safely on uneven terrain. LEO, the interplanetary explorer? It could happen.

Hint for today’s Strands puzzle

Today’s Strands theme is: The feeling is mutual.

If that doesn’t help you, here’s a clue: We go together.

Clue words to unlock in-game hints

Your goal is to find hidden words that fit the puzzle’s theme. If you’re stuck, find any words you can. Every time you find three words of four letters or more, Strands will reveal one of the theme words. These are the words I used to get those hints, but any words of four or more letters that you find will work:

  • GIVE, GIVER, GAME, GAMES, NONE, LICE, ZINE, TABLE, ABLE, BEAR, REEK, CONE, LICK, LICKER, ZONE, NOEL, REAL, LATE, LEAN, HONE, TAME.

Answers for today’s Strands puzzle

These are the answers that tie into the theme. The goal of the puzzle is to find them all, including the spangram, a theme word that reaches from one side of the puzzle to the other. When you’ve got all of them (I originally thought there were always eight but learned that the number can vary), every letter on the board will be used. Here are the nonspangram answers:

  • MESH, VIBE, AGREE, CLICK, RELATE, CONNECT, HARMONIZE

Today’s Strands spangram

Today’s Strands spangram is GETALONG.  To find it, start with the G that’s five letters down on the far-left row, and wind up and around.

Toughest Strands puzzles

Here are some of the Strands topics I’ve found to be the toughest in recent weeks.

#1: Dated slang, Jan. 21. Maybe you didn’t even use this lingo when it was cool. Toughest word: PHAT.

#2: Thar she blows! Jan.15. I guess marine biologists might ace this one. Toughest word: BALEEN or RIGHT. 

#3: Off the hook, Jan. 9. Similar to the Jan. 15 puzzle in that it helps to know a lot about sea creatures. Sorry, Charlie. Toughest word: BIGEYE or SKIPJACK

You Need to Clean Your Dirty Phone More Often Than You Think

Using the wrong products can damage the screen and protective coatings. Here’s the safest way to clean your phone.

Americans spend more than 5 hours a day on their phones, according to a December 2024 survey. With that much handling, it’s no surprise your phone becomes a hotspot for bacteria — in fact, it’s often dirtier than a toilet seat. Since you hold it constantly and press it to your face, making regular phone cleaning part of your routine is more than just smart, it’s necessary for your health.

The FCC suggests disinfecting your phone daily, but not all cleaning methods are safe. Harsh chemicals and abrasive materials can damage protective coatings and potentially harm your screen. To keep your phone both clean and intact, it’s crucial to use the right cleaning techniques.

Luckily, there are safe and effective ways to sanitize your phone without causing any damage. We’ll guide you through the best methods and products for keeping your device germ-free, no matter if you have an iPhone or a Samsung or whatever its level of water resistance.

For more cleaning tips, here’s how to clean wireless earbuds and AirPods. 

What are the best products for daily cleaning?

After touching surfaces that see a lot of action from the public — such as door handles, seats on public transportation, grocery carts and gas pumps — you might think you need a heavy-duty cleaning agent to use on your phone. However, you should avoid rubbing alcohol or products made of straight alcohol, since they can damage the protective coatings that prevent oil and water from harming your screen.

Some suggest making your own alcohol-water mix, but getting the concentration wrong can damage your phone. The safest option is using disinfectant wipes with 70% isopropyl alcohol. For daily cleaning, consider a UV light product like PhoneSoap, which kills 99.99% of germs and bacteria. We can also turn to phone manufacturers and cell service companies for guidance, too. 

Apple now approves using Clorox Wipes and similar disinfectants, which was not recommended before the pandemic since they were thought to be too abrasive on the screen’s coating. AT&T advises spraying a 70% isopropyl alcohol solution on a soft, lint-free cloth and wiping your device down. Samsung also recommends using a 70% alcohol solution with a microfiber cloth. Always make sure your phone is powered off before cleaning it. 

What are the best methods for removing fingerprints, sand and makeup?

Sometimes your phone needs a more specific treatment when washing up. The recommended process for daily cleaning may not be enough to remove pesky grains of sand after a beach vacation or tough foundation stains. 

Get rid of fingerprints

Fingerprint smudges are inevitable since your skin produces oils. Every time you pick up your phone, your screen will get fingerprints. The safest way to make your screen print-free is with a microfiber cloth. For a deeper clean, dampen the cloth with distilled water (never apply water directly to the screen) and wipe down the surface. This works for the back and sides of your phone as well.

Alternatively, try a microfiber screen cleaner sticker that sticks to the back of your phone for easy wiping.

Remove sand and small particles

Grains of sand and lint can easily get stuck in your phone’s ports and crevices. To remove it, we recommend you use Scotch tape. Press it along the creases and speaker, then roll it up and gently insert it into the ports. The tape will pull out any debris. You can then just simply throw away the tape for easy cleanup. 

For smaller speaker holes, use a toothpick gently or a small vacuum crevice tool to suck out the debris. These tools work well for other small appliances or hard-to-reach areas in your car too.

Cleanse makeup off your phone screen

When you wear makeup and skin care products, such as foundation and moisturizers, you’ll leave residue on your phone screen. While makeup remover works for your face, it’s not safe for screens due to potentially harmful chemicals. Instead, try a screen-safe makeup remover like Whoosh, which is alcohol-free and gentle on all screens.

Alternatively, use a damp microfiber cloth to clean your phone, then wash the cloth afterward. Make sure your cloth is only slightly wet to avoid soaking your phone in water. 

What if my phone is waterproof?

For waterproof phones (IP67 and above), it’s best to clean the device with a damp cloth instead of submerging or running it under water — even if the phone advertises that it can withstand submersion for a certain amount of time. 

Afterward, dry your phone with a soft cloth, ensuring all ports and speakers are patted dry. While your phone can withstand water, submerging it can lead to water in the ports, delaying charging. Remember, water resistance is meant for accidents, not swimming or regular cleaning.

Things to avoid when cleaning your phone

We’ve already covered why you should avoid makeup remover and rubbing alcohol, but those aren’t a comprehensive list of harmful cleaning agents. Here are a few other items and products you should never use to clean your phone: 

  • Hand sanitizer: Fragrances and ethyl alcohol found in many sanitizers can harm your phone. 
  • Window or kitchen cleaners: Harsh cleaners can strip the protective coating on your phone and leave it more vulnerable to scratches.
  • Paper towels: Paper can shred, making the debris on your phone much worse, and the rough texture can leave scratches on your screen. 
  • Dish and hand soap: Most soaps require you to combine them with water, and since you should keep water away from your phone, it’s best to stick to a damp cloth.
  • Vinegar: Like cleaners and alcohols, vinegar will strip your phone screen’s coating.
  • Compressed air: Blowing intense and direct air into your phone’s portals can cause damage, especially to your mic. Apple specifically warns iPhone owners not to use compressed air.
