The Science Is In Elephants Are Even Smarter Than We Realized Video

One day in 2010, while taking a stroll in his backyard, Kandula the elephant smelled something scrumptious. The scent pulled his attention skyward. There, seemingly suspended in the air, was a sprig of bamboo decorated with bits of cantaloupe and honeydew. Stretching out his trunk, he managed to get the fruit and break off a piece of the branch, but the rest of the tasty leaves remained tantalizingly out of reach....

To Close The Gender Gap In Wages We Need To Start Young

Children are natural negotiators. When taking on a tired parent, a six-year-old can adeptly turn five minutes more at the playground to 10 minutes more, the “last” episode into “just one more” and a kiddie-sized ice cream cone into a sundae with chocolate fudge and sprinkles. These negotiations—often exhausting (“Can I stay up for 10 more minutes? Please! Please! Please!”) and frequently hilarious (“I’ll be your best friend if …”)—seem worlds away from the negotiations children will be engaging in when they grow up and start their first jobs....

U S Fishermen Throw Away 1 Billion Annually In Catch

By Barbara Liston (Reuters) - U.S. commercial fishermen are throwing away about $1 billion worth of edible fish each year, according to a conservation group which is advocating for incentives to stop the waste. The quantity of so-called bycatch – that is, fish that wasn’t targeted but caught inadvertently – is estimated by the U.S. government at two billion pounds (907,185 tonnes) a year. The surprise was the quality of the bycatch that often is tossed back into the ocean dead or dying, said marine scientist Amanda Keledjian, author of the report from Oceana, a nonprofit international conservation group....

What Is Chernobyl Like Today

Eerie images from the site of the Chernobyl nuclear disaster still haunt us 30 years later. What is Chernobyl like today? On April 26, 1986, a safety test gone wrong led to an explosion in reactor #4 at the Chernobyl Nuclear Power Plant in Pripyat, Ukraine. (At the time, Pripyat was part of the USSR.) Several factors then conspired to result in an unprecedented, widespread scattering of over 100 radioactive elements into the surrounding towns and cities....

Why Do We Develop Certain Irrational Phobias

Katherina K. Hauner, a postdoctoral fellow at the Northwestern University Feinberg School of Medicine, answers: Under normal circumstances, fear triggers a natural fight-or-flight response that allows animals to react quickly to threats in their environment. Irrational and excessive fear, however, is typically a maladaptive response. In humans, an unwarranted, persistent fear of a certain situation or object, known as specific phobia, can cause overwhelming distress and interfere with daily life. Specific phobia is among the more prevalent anxiety disorders, affecting an estimated 9 percent of Americans within their lifetime....

A Candle Seesaw Balancing Act

Key concepts Physics Force Gravity Mass Lever Introduction When the days grow shorter and it gets dark early in the evening many people enjoy candlelight. Candles are also a great tool for doing science—so why not combine both and add a little light to your science? In this activity you will use candles to investigate the balancing forces of a seesaw. Background Seesaws are classic playground equipment for children. They are not only fun to play on but also provide an excellent opportunity to explore a type of simple machine designed to lift objects much heavier than your strength would normally allow....

A Fountain Of Youth For Your Mind

Whether we want to or not, we all age. So it is no surprise that a vast consumer industry exists for all things antiaging— creams, diets, mantras, contraptions, pills, surgeries and legitimate prescription drugs. To be sure, a robust area of scientific research is devoted to the topic. One of the most interesting findings to emerge is that longevity is closely correlated with intelligence. This may be discouraging for those who never graduated from Oxford, considering raw intelligence is a relatively stable psychological trait and not easily amplified by any intervention....

Ancient Mars Could Have Harbored Life For A Long Long Time

SAN FRANCISCO—Parts of Mars were capable of supporting life as we know it for lengthy stretches in the ancient past—perhaps hundreds of millions of years at a time, new observations by NASA’s Mars rover Curiosity suggest. Since it landed inside the Red Planet’s Gale Crater in August 2012, Curiosity has studied a number of different rocks over an elevational range of about 650 feet (200 meters), which represents a time span of tens of millions to hundreds of millions of years....

Booster Shots Against Scary Covid Virus Variants Are In The Works

Since the pandemic began, its viral cause—SARS-CoV-2—has been mutating. These genetic changes appeared inconsequential at first. But recently some alterations have produced variants with the unsettling potential to make the new COVID vaccines less effective, just as the shots have begun to make their way into people’s arms. Now, drug makers are responding by developing different follow-up shots against these variants to keep the disease at bay. These efforts mark the next phase in what’s shaping up to be a long battle between an ever-changing virus and the immunizations deployed against it....

Climate Change Might Make Birds Mis Time Their Migrations

Bird species trace their migratory paths based on where they can find the most resources, but changes to the climate might soon make their knowledge outdated. In a recent study, a team of scientists from the University of Copenhagen tracked the movement of three species — the common cuckoo, the red-backed shrike and the thrush nightingale — to identify what prompted their annual migratory routes. They found that the birds tend to gravitate to places that had the best supply of food, like insects, at different times of the year....

Fact Or Fiction Lead Can Be Turned Into Gold

For hundreds of years alchemists toiled in their laboratories to produce a mythical substance known as the philosopher’s stone. The supposedly dense, waxy, red material was said to enable the process that has become synonymous with alchemy—chrysopoeia, the metamorphosis, or transmutation, of base metals such as lead into gold. Alchemists have often been dismissed as pseudoscientific charlatans but in many ways they paved the way for modern chemistry and medicine. The alchemists of the 16th and 17th centuries developed new experimental techniques, medicines and other chemical concoctions, such as pigments....

Inventor Of Dreams

When members of the Chicago Commercial Club arrived to hear a lecture by the famed electrical inventor Nikola Tesla on May 13, 1899, they were startled by the sight of an artificial lake sitting in the middle of the auditorium. Everyone knew that Tesla–the man who had devised the alternating-current (AC) system that brought electricity into people’s homes and businesses–was a master showman. Six years earlier at Chicago’s Columbian Exposition, for example, the dapper engineer had dazzled spectators by sending 250,000-volt shocks coursing through his body....

Surprising Psychology Can Make The Country Healthier

Public health communications are designed to tackle significant medical issues such as obesity, AIDS, and cancer. For example, what message can best combat the growing obesity epidemic? Are educational messages effective at increasing condom use? Should cancer prevention messages stress the health risks of too much sun exposure? These are not just medical problems. These are fundamentally questions about perception, beliefs, and behavior. Psychologists bring a unique expertise to these questions and are finding consequential, and often non-intuitive, answers....

The Hidden Logic Of Deception

We lie to ourselves all the time. We tell ourselves that we are better than average – that we are more moral, more capable, less likely to become sick or suffer an accident. It’s an odd phenomenon, and an especially puzzling one to those who think about our evolutionary origins. Self-deception is so pervasive that it must confer some advantage. But how could we be well served by a brain that deceives us?...

The Idea That A Scientific Theory Can Be Falsified Is A Myth

J.B.S. Haldane, one of the founders of modern evolutionary biology theory, was reportedly asked what it would take for him to lose faith in the theory of evolution and is said to have replied, “Fossil rabbits in the Precambrian.” Since the so-called “Cambrian explosion” of 500 million years ago marks the earliest appearance in the fossil record of complex animals, finding mammal fossils that predate them would falsify the theory. But would it really?...
