In the age of unmanned missions to the moon, flowers might become the next iconic picture that will “stir enthusiasm for spaceflight.” And Paragon Space Development wants to be the first company to plant said flowers on the moon. Paragon’s CEO, Taber MacCallum, will plant the seeds in a greenhouse that has been designed to block off space radiation and withstand the moon’s extreme temperatures —which can dip to 240 degrees below Fahrenheit (F) at night and rise to 225 degrees F during the day.

Here’s how MacCallum plans to pull off his feat. First, the greenhouse (made of metal-reinforced glass) will hitch a ride on the Odyssey Moon, one of the competitors for the Google Lunar X Prize. When the greenhouse lands on the moon’s surface, the incubated mustard seeds will complete their life cycle, and bloom into six flowers (that’s all there’s room for). While it would take two weeks for a mustard seed to blossom into a flower on earth, it’ll take just a single lunar day for the flower to bud on the moon.

When you’re feeling stressed, do you need everything clean now? Do you also find everything and everyone getting in your way? Then the emotion-sensing Roomba vacuum cleaner is for you—it can sense if you’re feeling stressed or relaxed, and act accordingly.

If your stress level reads high, the robot will start cleaning but keep its distance, while if your stress is low, Roomba will come closer to you, as a pet does its owner.

A special headband captures biolectric signals from your forehead, and control software then translates your muscle tension readings into how much stress you’re feeling. The more tense your muscles, the higher your stress level is interpreted to be.

If your reading falls in between either extreme, the robot will continue in its current mode until the stress level reaches a threshold that tells it to change behavior.

“While p-zombies are logically possible but naturally improbable, an approximation of i-zombies actually exists”

So, what happens when an i-zombie is trapped in a p-zombie’s body?

Think washing your hair is a harmless act of hygiene? Think again! That is, if researchers into the dark sides of shampoo have anything to say about it.

It turns out that a fragrance used in many shampoos is a common allergen that may even cause eczema. Air-oxidized linalool, which is present in up to 80 percent of shampoo products, has been ranked as the third most common eczema-causing substance, falling behind only nickel and cobalt.

And even if you escape the eczema, once you wash and send those suds down the drain, they start spreading drug-resistant bacteria, according to new reports. Sewage sludge collected by municipalities contains antibiotic-resistant microbes that grow faster in the presence of chemicals in shampoo and household detergents.

On the plausibility of Superman’s x-ray vision

•Plants can twitter, but it seems celebrities can’t—not on their own, anyway.

• Toxic sofas, after being shipped from China with packets of a harmful mold-inhibitor, caused extreme skin rashes and burns on at least 1,600—and possibly tens of thousands not yet identified—people in England.

• Science education is under assault in Texas.

• In another move of, weirdly, putting animals on birth control, China is putting gerbils on the pill.

• Daddy long-legs are threatened by climate change, a gorilla suffered a seizure and was given an MRI, and a campaign helps endangered species by enlisting clothing brands to save their namesakes: Lacoste to the crocodiles’ rescue!

• Also, we’re doomed.

It’s an ironic invention in a country that takes its pizza seriously, even pushing for pizza-policing legislation. But this culinary “cultural commodity” for Italy can now be made—fresh!—by a vending machine.

“Let’s Pizza” is a bright red machine that, using technology developed at the University of Bologna, kneads flour and water into dough, forms it into the classic round shape, spreads the sauce and adds the toppings of a customer’s choosing—either cheese and tomato, ham, bacon, or fresh vegetables. The pizza then bakes in an “oven” that uses infrared rays, and when finished, slides right out into the hungry customer’s hands.

“A 63-year-old woman developed acute back pain and sciatica after playing hula-hoop”

This gem comes from a medical review published in 1959 by ZH Zaidi, “Hula-hoop syndrome“.
