【推荐1】Less than three months after a gunman walked into Marjory Stoneman Douglas High School, killing 17 students and teachers, seniors on Saturday night will celebrate their prom.

Still, the Parkland high school prom will be far from ordinary. Not only will it be held under tight security, but there will be a tribute honoring the lives of the four seniors killed during the February 14 tragedy.

With some students still saddened and emotions running high, local businesses, vendors and community members have come together to offer products and services at cost or even free of charge, in hopes of relieving students of their burdens- even if just for a night. The event should involve all the hallmarks of a typical American prom: eye-grabbing decorations, lots of flowers and a dance floor packed with students dressed to the nines.

The biggest contribution came from the Westin Fort Lauderdale Beach Resort, which has donated a ballroom and catering for the evening. The money saved allowed the prom planning committee to charge as little as $30 per ticket- down from the usual of about $100.

Other businesses also stepped up, offering hairstyling, makeup, photography and even prom dresses. To help ease students' pain, Gabriela Miller, an alumni and salon and spa owner, asked her staff to donate their time and services to girls preparing for the prom. They enthusiastically agreed. On Saturday, Miller and dozens of beauty experts from surrounding communities will do hair and makeup for more than 230 girls.

Apart from business, neighbors also did their part. Shawn Rosenthal, who lives a few miles south of Parkland, felt so moved by the attack that she organized a collection to provide free prom dresses to senior girls. Within days, with the help of her friends, they'd collected more than 100 prom dresses of all colors, shapes and sizes. They caught the eye of the Alumni Association, which was also gathering dresses, and pooled their efforts.

Such a community effort could help the students “heal for a moment.”

【推荐1】Most of us are familiar with the concept of six degrees of separation — the idea is that anyone in the planet can be connected to anyone else in just six steps. But is there actually any science to back up this commonly cited theory?

If you just take a look at the following numbers, the six degrees of separation idea seems pretty plausible. Assuming everyone knows at least 44 people, and that each of those people knows an entirely new 44 people, and so on, the math shows that in just six steps everyone could be connected to 44⁶, or 7.26 billion people — more than are alive on Earth today.

But this idea wasn’t scientifically tested until the 1960s, when a psychologist sent 300 packages out to people in Nebraska and Boston, and asked them to use their networks to get them back to one specific target — a stockbroker (股票经纪人) living in Boston. They weren’t asked to forward it to him directly, but to send it to someone they knew on a first name basis, with instructions for that person to forward it on to someone in their network that they thought might know the stockbroker.

Only 64 of those packages actually reached the target, with an average path length of just 5.2 intermediary (中间人) connections, and this experiment was used as evidence for six degrees of separation, or the “small world phenomenon”, as the researcher called it.

But Derek Muller, a researcher, dug a little deeper, and found that, of the original 300 packages, 100 were sent to people already living in Boston (where the target also lives) and 100 were sent to stockbrokers who shared a profession with the target, so there were really only 100 purely random packages sent out. And of those 100, only 18 made it back to the target. “So we’re talking about a sample size of 18 — that’s all the evidence there was for six degrees of separation,” Derek explains.

Lead author Associate Professor Simone Ciampi from Curtin’s School of Molecular and Life Sciences said this easy, low-cost method of determining how to produce and keep the highest energy charge in a capacitor (电容器). could be of great benefit to all scientists, engineers and start-ups looking to solving the energy storage challenges of the future.

“All electronic devices require an energy source. While a battery needs to be recharged over time, a capacitor can be charged instantly because it stores energy by separating charged ions (离子), found in ionic liquids,” Ciampi said.

There are thousands of types of ionic liquids, a type of “liquid salt”, and until now, it was difficult to know which would be best suited for use in a capacitor. What our team has done is designing a quick and easy test, able to be performed in a basic lab, which can measure both the ability to store charge when a solid electrode touches a given ionic liquid—a simple capacitor—as well as the stability of the device when charged.

“The simplicity this test means anyone can apply it without the need for expensive equipment. Using this method, researchers found that charging the device for 60 seconds produced a full charge, which did not ‘leak’ (渗漏) and begin to diminish for at least four days,” Mr Belotti said.

The next step is to use this new screening method to find ionic liquid with an even longer duration in the charged state and larger energy density.
