Talk about suiting up for a jog — researchers have developed an exosuit that helps runners use less energy.

The ensemble is no stiff, Iron Man-style exoskeleton — it looks more like a pair of belted spandex shorts. In the study, recently published in Science Robotics, researchers say that wearing the suit can cut the metabolic cost of a treadmill run by 5.4 percent.

For fish, the good and bad of warming ocean waters

Jun 19, 2017

As ocean temperatures rise, what will happen to the fish we eat?

According to a recent study published in “Progress in Oceanography,” some fish species will thrive in warmer waters — and others, not so much.

Using a detailed climate model and historical observation data, researchers at NOAA and The Nature Conservancy modeled the shifting thermal habitats of over 50 species along the Atlantic coast, from North Carolina to the Gulf of Maine.

How to make bionic limbs feel more natural

When you flex your bicep, your muscle sends information to your brain, allowing you to feel your muscle contract without even having to glance at it. But if you have a bionic limb, you don’t get that same sensory feedback.

“When I move my bionic ankles, I don’t feel the movement of the ankles, and when the torque increases on my bionic ankle joints, I don’t feel that torque,” says Hugh Herr, who co-directs the Center for Extreme Bionics at MIT, and whose legs are amputated below the knee.

Just how much science is in forensic science?

On TV crime shows, forensic science always just manages to pinpoint the criminal in the span of a televised hour — and with 100 percent accuracy. But in real life, forensic science doesn’t always work so smoothly.

This August communities across the United States will witness a total solar eclipse for the first time almost 100 years. This event is both a visual spectacle for sky watchers and a significant scientific event.

With the rise of a competitive market for personal gene testing, the tool is becoming more available and affordable to the public. People can now swab their cheek, send the sample off to a lab, and wait patiently for a private company with a massive gene database to tell them where in the world their genes are from. But what do these tests reveal about personal identity and what do they imply about race? 

The story of Magnus Hirschfeld, the ‘Einstein of sex'

Via Undiscovered

Decades before Alfred Kinsey developed his scale for human sexuality, there was Magnus Hirschfeld — a doctor who dedicated his career to proving that homosexuality was natural.

Hirschfeld’s reasoning was simple: In turn of the 20th century Germany, where he lived, a law called Paragraph 175 made so-called “unnatural fornication” between men punishable by prison time.

Have you gotten your hands on a fidget spinner yet?

The brightly colored device can be spun, flipped and even tossed in one hand, and it’s been turning up in schools across the country.

Manufacturers say the fidget spinners can help relieve stress, but the toys have already been banned as distractions in some classrooms, sending kids back to the Stone Age of clicking pens and squeezing stress balls.

The banana is always in season and always available at the grocery store. A new book explores how the prevalence of the popular fruit is a model for the dangers of a food system that is increasingly dependent on fewer food staples.

“Never Out Of Season” (Little, Brown, and Company/2017) by biologist Rob Dunn, a professor in the department of applied ecology at North Carolina State University, walks readers through the precarious corporate food system and explains how diversity is crucial to crop survival.

With stories of unhappy air travelers blanketing social media in recent months, one major airline is trying something new.

Delta Air Lines plans to install special bag-check kiosks at Minneapolis-St. Paul International Airport, giving customers the chance to skip waiting in line for an agent. One of the new kiosks will include facial-recognition technology, using a camera to confirm passengers’ faces against their passport photos.

Popularity is often a concern for teenagers, but research shows it also influences life outside the high school cafeteria. Children as young as four years old can identify their most popular peer, and one’s popularity growing up can even predict his or her lifespan.

In the new book “Popular: The Power of Likability in a Status-Obsessed World” (Penguin Random House/2017), Mitch Prinstein teases apart the distinction between two different types of popularity: likability and status. 

Science has some good news for worriers

Whatever it is that you’re fretting about, here's a bit of good news: Worrying can be beneficial, under certain circumstances.

Dr. Kate Sweeney, an associate professor of psychology at the University of California, Riverside, and co-author of new research on the upside of worrying, says it serves a few useful functions.

“The most important function that worry serves is that it acts as a motivator,” Sweeney says. “It essentially tells us there is something we should be doing. And it gives us the motivation to do it.”

This year marks 50 years since the first microwave oven entered home kitchens. Called the Radarange, the machine sold for a whopping $495 in 1967, and we’ve been nuking our food ever since — but not without lingering questions about how the appliance even works.

Consider, for a moment, the musk ox.

The ancient animal looks a bit like a shaggy, long-haired bison and can be found roaming the cold, Arctic landscapes of places like Alaska, northern Canada and Greenland

Musk oxen “actually went extinct in Alaska in the 1890s, and the state brought them back,” says wildlife biologist Joel Berger, a professor at Colorado State University and senior scientist for the New York-based Wildlife Conservation Society.
