Baffling Ways Plants Are Kind of Like Humans

We all know that plants are alive, but we definitely don’t think of them as being alive the same way as people or animals are alive. After all, a plant definitelydoesn’t have a face, a brain, a heart, blood or any other mammal-like characteristics. Heck, plantscan’t even move!

Most of us never seek to understand just how complex of an organism a simple houseplant, a delicate flower or a huge tree really is. We may appreciate them for being a beautiful (and necessary) part of nature or for being a super nutritious food source, but anything past that is left mostly out of our understanding and awareness unless of course you’re a botanistor a super experienced gardener.

Want to enhance your appreciation for plant life? If you do, have a quick read through afew of these interesting plant abilities that other living things havetoo.

Plants can make calculated decisions based on risk.

Plants can’t move around like animals can, so that means they have to be able to carefully sense changes in their environment in order to make adjustments necessary for their survival. In arecent study, scientists examinedhow the garden pea plant would respond to different environments by plantingits roots between two different pots.

One pot hada constant nutrient leveland the other pot with a varying nutrient level. Although both pots had the same average nutrientlevel, the scientists found that after a 12-week growth period, some of the pea plants involved in the experiment decided to “gamble” by growing more of their roots in the varying pot while other risk-averse plants decided to stay with their steady pot.

Plants can store memories.

Ever wonder how plants are so good at syncing up with the seasons? Being able to detect the changing amount ofdaylight is one thing, but scientists now know that plants also figure out how to bloomand flower in response to seasonal changes by”remembering” previously experienced environmental conditions so that they can predict and prepare for change.

Prion proteins are what scientists think may be responsible for plant memory. A protein known asluminidependensthat helps plants shift their growth according to temperature and light might act likea prion, which at this point offers the best understandingof protein-based molecular memory.

Plants communicate with neighboring plantsand other organisms.

Plants can talk to each other, to insects and even to other mammals when they’re under threat or wounded. Threatened or wounded plants are known to release proteins that signal nearby plants to strengthen their defenses.

Some plants, such as the wild tobacco plant,will also release signalsto call for help from “good” predatorsto come destroy the “bad” pests. So, for example, if the wild tobacco plant detects signs of thehornworm caterpillar by sensing andidentifying its saliva on its leaves or stems, it will release a protein signal that appeals to the caterpillar’s enemies (other predatory insects) to come on over and get rid of them.

Plantscan see, smell, taste, feel and maybe even hear.

Plants actually have their own complex versions of seeing, smelling, tasting and feeling what’s presently in their surroundings to help them survive. According to scientist Daniel Chamovitz in an interview with Scientific American, plants can “smell” pheromones emitted by other plantsand then sync up to them by blooming or ripening along with them.

You probably already know that plants can actually bend toward the light too, suggesting that they can “see” where they can get the most light from. They can “taste” through their roots in a way that supportsroot-to-root communication with nearby relative plants, they can “feel” the temperature or weather conditions change using mechanoreceptors in their cell membranes. Some not-so-scientific experiments suggest they can even “hear” music in ways that might influence their growth.

So next time you take a stroll outside somewhere among the trees or next time you glance over at your favorite houseplant, consider how beautifully complex and astounding plants really are. They don’t exactly resemble humans, mammals or other mobile organisms, but they certainly do have their very own unique ways of sensing the world around them that we can sort of relate to on a very broad, survival-focused level.

Paying extra to get that new iPhone faster? It’s a bad deal

Paying extra to get that new iPhone faster? It’s a bad deal

The problem with tech companies — you know, besides all of these ones — is that when it comes to fighting climate change, they’re about as committed to the cause as your friend was that one time she went vegetarian for a guy.

Sure, the big tech giants like Google, Microsoft, and Apple can throw money at the problem. Or they can build little eco-utopias for themselves, where their workers can forget about all the poverty, pollution, and tragic dearth of free snacks that plague the real world. But considering that these companies have tremendous power over society through the devices and services that they sell us, none of that really matters. Until they make sustainability as important to their core operations as sleek aesthetics and performance, they’ll continue to be part of the problem.

Exhibit A: The smartphone industry’s new “equipment installment plans.” These plans allow consumers to lease smartphones with monthly payments, rather than buy them outright. They also allow consumers to upgrade to a new phone every year, rather than suffer through the two whole years that it usually takes to get an upgrade through standard plans.

The New York Times did a price comparison on the two options for various phone companies and found that it’s actually cheaper to just buy the phones outright. For a 64GB iPhone 6S you might pay Apple, AT&T, or Verizon a total of $438.96, $450, and $425.07 a year, respectively. By contrast, if you just buy a $750 iPhone and use it for two years, that’s $375 per year. Plus, the Times points out, you could then just sell that old phone for around $175.

Basically, the main incentive to lease a smartphone is to get an early upgrade, which, the Times concludes, might be a good enough reason for someone who can afford it.

But woefully absent from this discussion over whether or not it’s better to buy or lease a phone is any mention of sustainability — save for one lone voice of reason at the end of the article:

“Why do we constantly need new things?” said Kyle Wiens, the chief executive of iFixit, a company that sells parts for people to repair products. “Why can’t we be happy with what we have?”

In an ideal world, where we all live in eco-utopias, I understand how to do my taxes, and sustainability is an integral part of tech culture, these companies — and the media outlets that cover them — would have to answer questions like: How many new phones would factories have to churn out every year if everyone opts for these frequent upgrades? How much would that increase resource extraction? What eventually happens to all of these leased phones? Is e-waste going to be a problem? Because if we’ve learned anything in recent decades, it’s that we’re in for a rough ride, unless we fundamentally change how we think and live on this planet — and that means throwing away our throwaway culture.

But alas, sustainability isn’t an integral part of tech culture at the moment, just like your friend’s foray into the veg life wasn’t part of some new moral code. In the end, they’re all just in it to impress someone.

This New Charger Checks To See If Your Phone’s Been Hacked

The increasing ubiquity of smartphones has made these little computers an appealing target for hackers. Most phones operate on one of the two main mobile operating systems—Apple’s iOS and Google’s Android—and Android’s open nature, along with the ease with which it lets you download off-market software, has made it hackers’ favored target.

This isn’t a huge problem, if you’re careful. But, if you are downloading a lot of software outside of the official channels, you may be opening the door to your phone’s innards to malware. Quartz:

About 15% of the apps flagged by Verify Apps are commercial spyware, a diverse set of monitoring apps that range from tracking internet behavior to improve advertising to the very malicious keyloggers that collect personal information entered by the user and report it to the malware creator.

Many software hacks and bugs rely on code that prevents the computer’s built-in security from detecting the problem, either by tricking the anti-virus software into thinking the hack is harmless or by somehow masking it from view. To combat this kind of attack, says MIT Technology Review, the company Kaprica Security has designed a mobile charger that will scan your phone for malware while juicing its battery. Tech Review:

For the user, the charger is simple: plug it into the wall, and plug the phone into the charger. The charger then conducts a quick preliminary scan of the phone; if all is in order, it shows a green light.

If you leave the phone plugged into the charger, it will reboot at a time you’ve preconfigured—3 a.m., for instance—and start a more thorough process that sends the phone’s operating-system files to the charger for an analysis that takes about four minutes.

…If a problem is detected, the charger will alert you with a red light, and—depending on the user’s preferences—the charger can automatically repair the phone by using a previous “good” version of the operating system it has already stored.

The idea behind the charger is that, being independent of the phone, the charger wouldn’t be fooled by the tricks meant to confuse the phone’s protections.

That being said, we can’t help but be a little bit nervous about a company with a name like Kaprica Security. What if the charger is actually just paving the way for the Cylon invasion?
