Study begins to reveal genetic ties behind a neurological phenomenon

Mar 31, 2018

When you hear a particular piece of music, can you see an accompanying color? Or do certain letters stir up certain colors?

If you answered “yes” to these questions, than you may have what is known as synesthesia. An estimated four percent of the world’s population have the neurological condition that may best be described as a blurring of the senses.

Marie Curie is a double-Nobel Prize winning scientist and often the first name mentioned when the topic of women in science comes up.  Neuroscientist-turned-designer Amanda Phingbodhipakkiya admits even she struggled to think of female scientists beyond Marie Curie, but there are plenty of women the history books forgot about.

It maybe be hard to believe, but the 20th anniversary of the International Space Station’s initial launch will take place in November. In those soon-to-be two decades, the ISS has proven to be immensely helpful in helping facilitate research on microgravity — and it remains the only destinations for astronauts moving through Earth’s lower orbit.

New book looks at medical cures now considered 'quackery'

Mar 23, 2018

Placing red-hot irons on someone's temple for headaches. Drinking mercury for syphilis. Rubbing pimples on dead bodies for acne. All of these remedies to various maladies seem ridiculous now, but at one point they were not.

They are just some of the some of the crazy “medical cures” that are highlighted in a new book written by Lydia Kang: “Quackery: A Brief History of the Worst Ways to Cure Everything.”

New book explains the secrets behind famous skyscrapers, other structures

Mar 23, 2018

Roma Agrawal spends a lot of time thinking of the sheer power of concrete. She’s a structural engineer who helped design The Shard in London, an iconic 95-story skyscraper that opened in 2012.

“What I really like about it is that it has so many different forms,” Agrawal says. “It's quite an indeterminate material … I just love the fact that it can be anything you want it to be."

Chinese space station likely to land in Europe in a few weeks

Mar 23, 2018

Sometime this spring, a falling Chinese space station will crash to Earth. That is known. What is not as clear is when it will hit — or where.

“Scientists have left it pleasantly vague,” says Maggie Koerth-Baker, a senior science reporter for FiveThirtyEight.com.

AI-based fake videos pose the latest threat to what we perceive as reality — and possibly our democracy

Mar 18, 2018

First, “fake news” from questionable news sites permeated social media during the 2016 presidential campaign. Now, behold the next trend in skewed reality that experts say could threaten US democracy: fake videos that appear authentic by embedding real people's faces onto other bodies through artificial intelligence algorithms. It has sparked a debate on how to verify videos shared online.  

This phenomenon also began during the presidential campaign. People began slicing videos to falsely make it look as if events took place.

The next time you're visiting a website and your computer’s fan starts going crazy out of nowhere, there could be nefarious activity behind it.

New study sheds light on the debate over the origins of flamingos in Florida

Mar 10, 2018

Florida. Flamingos. The alliteration rolls right off the tongue. Yet for years there has been a question raised about whether the birds are actually native to the Sunshine State — a situation that could have major implications for the management of the species.

The ozone hole over the Antarctic is beginning to fill up. Here's the bad news.

Mar 4, 2018

Before the term global warming entered our collective lexicon, environmentalists and scientists had expressed major concern over the depletion of the ozone, the layer of gas that protects the Earth from extremely harmful solar ultraviolet (UV) rays. 

This heightened awareness led to the international adoption of the Montreal Protocol in 1987, in which major restrictions were placed on products that contained chlorofluorocarbons (CFCs) — thought to be the biggest culprit in the matter.

Giant chocolate industry depends on tiny insects for survival

Mar 3, 2018

Chocolate is a global industry worth about $100 billion a year. What gets overshadowed in all those sweet treats and big profits are the bugs responsible for it all.

Yes, bugs.

Chocolate comes from cacao beans, which come from the tiny flower of the cacao plant. Those plants are pollinated by even smaller flies called biting midges. For years, the flies have been the focal point of research by Samantha Jay Forbes, a doctoral candidate in agriculture and environment at James Cook University in Australia.

A cure for the flu? It could be as simple as sitting under a lamp.

Feb 27, 2018

It’s an annual rite of fall and winter that everyone tries to avoid: flu season. This season, the influenza virus has been particularly brutal in the United States, claiming the lives of 84 children in the US alone.

A new study has recently come out could shed some new light — so to speak — on how to kill the flu bug before it has the ability to show up in your system.

Naked mole rats may not be the most attractive creatures on the planet, but what they lack for in looks, researchers say, they more than make up for in genetic wonders.

The list of biological anomalies tied to these small rodents is long and jaw-dropping. They include the ability to survive 18 minutes without oxygen, a practical immunity to cancer and Alzheimer’s and other diseases associated with aging. They also have the ability to live longer than any animal its size — up to 30 years.

In early November, Strava — a technology company that can track athletic activity for its users through its website and app — released an article on Medium that proudly announced its first major global “heat map” that the company had released since 2015.

The article contains a list of astounding numbers including a billion activities, three trillion latitude/longitude points, 13 trillion rasterized pixels, 10 terabytes of raw input data and 17 billion miles covered.

For years, China has been associated with dirty, smog-filled air — so much so that it has become custom for some hotels to give guests complementary masks. Recently, though, the country has started making large strides to clear the air.

It’s been said that music is a universal language. To a group of researchers who are mostly from Harvard University, it’s more than a trite saying: It's an idea that formed the basis of extensive work to get a better feel for that universality — regardless of cultures or geography.

Do songs share social functions around the world, such as being used to meet people at a dance, calm fussy infants or heal illness? Do they have convergent or contextual features such as the instruments being used, the gender of the singers or a similar melodic or rhythmic complexities?

In spite of a request from the director of Centers for Disease Control (CDC) for Americans to get vaccinated, only 40 percent of the US population had received the flu vaccination by November.

Looking for a good night’s sleep? You’re not alone. More than a third of adults aren’t getting the recommended seven hours of sleep (never mind the ideal eight), according to a report from the Centers for Disease Control and Prevention (CDC) in 2014.

Predictive algorithms have been aiding us for years (see several of Google’s products, for instance) under the guise of making our lives easier by helping us make decisions.

But when do predictive algorithms cross the ethical line? Recently more jurisdictions at the state and local levels in the US have been buying software products from companies that use such algorithms along with data mining to make decisions that could have irreversible impacts on individuals and communities — such as determining jail sentences and predicting public policies.

North Carolina Central University has joined Duke, UNC Chapel Hill and N.C. State Universities as a full partner of the Triangle Universities Nuclear Laboratory. The lab, called TUNL (like, "tunnel") for short, is one of four Department of Energy Centers of Excellence for nuclear physics in the country.

As cold weather grips a majority of the country, it may be easy to think that all life is dead when the ground is frozen, at least until spring breathes new life into the plant systems and surrounding environments.

The signs have been there all along when it comes to using mechanical stimulation to stimulate regeneration and growth of tissue by simply pulling or pushing on cells. Think of a pregnant woman whose womb expands as the baby grows or a doctor telling a patient to lift weights to fight off osteoporosis by promoting bone growth.

It takes a lot to evolve a tail worthy of combat. Researchers at N.C. State University have found that only huge, slow vegetarians with body armor developed weaponized tails.

How much do you know about the science that goes into making bourbon? One would think the citizens of Kentucky — the epicenter of the corn-based whiskey — would know more than the average Joe on the topic.

At a taping of PRI’s Science Friday with Ira Flatow earlier this year at the Brown Theatre in Louisville, two teams composed of local bourbon enthusiasts tried their luck at a few questions connected to the popular hard liquor. The teams’ names reflected two the most popular bourbon-based concoctions: Hot Toddy and Old Fashioned.

Get out and get some fresh air. This phrase has been uttered for decades in an attempt to promote the exercise of walking, which has always been thought to have health benefits for nearly everyone's cardiovascular system.

Scientists warn we may be creating a 'digital dark age'

Jan 2, 2018

You may think that those photos on Facebook or all your tweets may last forever, or might even come back to haunt you, depending on what you have out there. But, in reality, much of our digital information is at risk of disappearing in the future.

Unlike in previous decades, no physical record exists these days for much of the digital material we own. Your old CDs, for example, will not last more than a couple of decades. This worries archivists and archaeologists and presents a knotty technological challenge.
