California Just Issued a Health Warning for Cell Phones—But It's Not as Scary as It Seems

The cell phone's reputation as a health risk is nearly as old as the technology itself. Worried consumers have blamed the device for everything from cancer to infertility, but with little evidence to back up these claims, experts have been split on the issue. Now California has come out with a list of guidelines in response to these supposed risks, Forbes reports.

The California Department of Public Health (CDPH) released the warning [PDF] earlier in December following a lawsuit from University of California-Berkeley researcher Joel Moskowitz. Moskowitz claimed that the state of California was putting citizens in danger by withholding information on the potential side effects of cell phone usage.

The newly released document focuses on avoiding radiofrequency (RF) energy specifically. Cell phone signals are one source of RF energy, and because it's a type of radiation, it's a common source of phone-related cancer fears. The CDPH recommends reducing exposure to the energy waves by sending text messages instead of making calls, using the speakerphone or a headset when talking on the phone, and carrying your phone in a bag rather than your bra, pocket, or belt holster. The department also suggests breaking the habit of sleeping with your phone in your bed, or at least turning it off or activating airplane mode before falling asleep.

Cell phones release more RF energy at some points than others, like when you're traveling in a vehicle, streaming or downloading content, or using a phone in an area where the signal is weak. But even when RF energy from cell phones is at its strongest, it's still not as great as the radiation from X-rays or ultraviolet rays from the Sun, and the jury's still out over whether it poses a threat to your DNA at all.

Past research linking RF energy to brain cancer has come with some major caveats: One study found that rats exposed to RF energy were more likely to develop brain tumors, but those rats were hit with seven times the radiation a person would get from a cell phone (and also they were rats, so not a perfect replacement for humans). Even the CDPH acknowledges the limits of the evidence in the studies it cites:

These studies do not establish the link definitely, however, and scientists disagree about whether cell phones cause these health problems and how great the risks might be.

So if it makes you comfortable, go ahead and sleep with your cell phone on your night stand instead of under your pillow. But maybe don't use the warning as an excuse to start declining all your calls.

A Simple Skin Swab Could Soon Identify People at Risk for Parkinson's

More than 200 years have passed since physician James Parkinson first identified the degenerative neurological disorder that bears his name. Over five million people worldwide suffer from Parkinson’s disease, a neurological condition characterized by muscle tremors and other symptoms. Diagnosis is based on those symptoms rather than blood tests, brain imaging, or any other laboratory evidence.

Now, science may be close to a simple and non-invasive method for diagnosing the disease based on a waxy substance called sebum, which people secrete through their skin. And it’s thanks to a woman with the unique ability to sniff out differences in the sebum of those with Parkinson's—years before a diagnosis can be made.

The Guardian describes how researchers at the University of Manchester partnered with a nurse named Joy Milne, a "super smeller" who can detect a unique odor emanating from Parkinson's patients that is unnoticeable to most people. Working with Tilo Kunath, a neurobiologist at Edinburgh University, Milne and the researchers pinpointed the strongest odor coming from the patients' upper backs, where sebum-emitting pores are concentrated.

For a new study in the journal ACS Central Science, the researchers analyzed skin swabs from 64 Parkinson's and non-Parkinson's subjects and found that three substances—eicosane, hippuric acid, and octadecanal—were present in higher concentrations in the Parkinson’s patients. One substance, perillic aldehyde, was lower. Milne confirmed that these swabs bore the distinct, musky odor associated with Parkinson’s patients.

Researchers also found no difference between patients who took drugs to control symptoms and those who did not, meaning that drug metabolites had no influence on the odor or compounds.

The next step will be to swab a a much larger cohort of Parkinson’s patients and healthy volunteers to see if the results are consistent and reliable. If these compounds are able to accurately identify Parkinson’s, researchers are optimistic that it could lead to earlier diagnosis and more effective interventions.

7 Smart Cleaning Devices to Help Keep Your Allergies at Bay

Just because you hate cleaning doesn’t mean you need to live in filth. You may not be able to buy a robot maid straight out of The Jetsons (yet), but there are plenty of automated ways to clean your house, if you’re willing to shell out a few extra dollars for the joy of watching a machine do your work for you. Here are seven pieces of technology that can help you combat dust, dirt, and allergens at home without lifting a finger.

1. iRobot Roomba

The Roomba has long been the gold standard in robotic vacuuming. While it may not be as effective as the human hand at getting into tight corners and over thick rugs, there’s no better way to clean the entire house while you sit on the couch watching television. You can preschedule cleanings so that your handy helper tidies up while you’re at work, and acoustic sensors help the robot flag particularly dirty patches of floor for extra attention. Newer versions are compatible with the Amazon Echo, meaning you can vacuum your home without even pressing a button. The higher-end models offer even more features: Roomba 900 series maps out its route through your home in the iRobot app to give you precise data on where it cleaned and what areas it spent the most time on, while the Roomba i7+ can empty its own dust bin.

Buy it on on Amazon starting at $270. In addition to Amazon, you can get the budget Roomba 675 from Best Buy, Walmart, or the retailers below:

2. Hoover REACT Vacuum

Hoover's REACT series of vacuums takes the upright to new heights. Outfitted with FloorSense technology, these smart vacuums know when you move from carpet to hard wood to tile, and can adjust the brush speed accordingly: On carpet, it'll use a faster brush speed to lift out stubborn dirt; when you move from the bedroom to the kitchen, the brush will slow down to prevent dirt debris from spreading. The REACT line is also Bluetooth compatible, so you can connect to the Hoover app in order to customize your FloorSense settings and monitor your machine's filter. The icing on the cake (for the pet-loving Mental Floss staff) is its superior suction and sealed allergen system that banishes pet hair from your upholstery and floor (at least temporarily).

Buy it on Amazon ($174), Walmart ($174), or from one of the retailers below:

3. Braava Jet

While iRobot’s foray into automated mopping isn’t as advanced as its vacuuming products, the Braava jet mopping ‘bot, first released in 2016, makes a decent pass at cleaning kitchens, bathrooms, and wood floors. Designed for any hard surface, the Braava 240 comes with three different settings—wet mopping, damp sweeping, and dry sweeping—and can be controlled using the iRobot app. The petite cube vibrates stains and dirt away using disposable pads ($8 for a 10-pack or $14 for two reusable pads) specific to the cleaning setting. The pricier, newer model, the Braava 380t, has just two settings—dry or a wet—but it can mop for up to 150 minutes on a single charge and is compatible with Swiffer and other cleaning cloths.

Buy it on Amazon ($170), Walmart ($185), or at one of the retailers below:

4. Everybot

Funded on Indiegogo in 2017, the Korean-made Everybot packs more power than the Braava. It’s a little bigger and can’t be controlled by an app, but its dual-spinning mops are designed to tackle spills and tough stains across the house with one touch of a button. It comes equipped with six different cleaning patterns as well as the ability to control its direction manually with a remote control. The mopping pads can be thrown in the washing machine or scrubbed by hand. It can also function as a duster: The robot has a handle on top, and you can grab it and run it over any surface, including windows.

Buy it on Amazon for $304 or from one of the retailers below:

5. Litter-Robot

No one likes a full litter box—not even your cat. So unless you’ve trained your cat to go in the toilet, you could probably use a litter box robot to keep your scooping duties to a minimum. The Litter-Robot looks a little like a kitty rocket ship and can save you some major smells. When the cat steps on the sensor upon entering the box, it triggers a countdown clock to the next cleaning cycle. Seven minutes later, when your cat is long gone, the orb-like litter box rotates, sifting the waste down into a filtered storage bin below. You only need to empty out the waste bin every few days as it fills up, and there’s never a smell—perfect for a house with multiple cats. Some reviewers note that it cuts down on their litter-and-dust triggered allergies, too.

Buy it from Litter-Robot for $449.

6. Awair Air Quality Monitor

Get to the root of your airborne allergy problem by cleaning up the air you breathe. Awair tracks the five main factors contributing to the air quality in your home—temperature, humidity, carbon dioxide levels, chemicals, and dust—and provides recommendations for changes you can make in order to improve your air quality. Awair is also compatible with Amazon Echo, Next, and IFTTT, which means it can direct your smart switch to turn on your humidifier if the humidity level drops, turn on the AC if your home gets too hot, or notify you if carbon dioxide levels rise. (The company also makes a smaller version called the Awair Glow that doubles as a smart plug.)

Buy it on Amazon for $163 or from one of the retailers below:

7. GermGuardian 4-In-1 Air Cleaning System
