Researchers estimate there are 751,527 pairs of Adélie penguins residing on the Danger Islands.

1.5 million penguins found on Danger Islands

Over the last several decades, scientists have noticed a steady decline in one of Antarctica’s most treasured inhabitants — the Adélie penguin. These penguins reside exclusively along the Antarctic coast, along with the emperor penguin. However, a recent study published on March 2 in the journal Scientific Reports states that a supercolony of over 1.5 million Adélie penguins has been found in a group of islands off the tip of the Antarctic Peninsula


Gene editing method can work on DNA and RNA

CRISPR-Cas9 is a molecular genetic method that allows scientists to cut DNA at specific sites of the genome. Traditionally, the technique has been used in animal models to delete certain genes from the DNA in order to attack viruses or correct genetic defects.


Outdated beliefs are halting social progress

Anytime someone announces that they believe the earth is flat, they are met with immediate dismay, criticism or even mockery. Now I am not saying that it is not warranted, but I wonder why such a reaction is not the standard response to scientific ignorance.

The sugars in candy can penetrate the liver and raise blood glucose.

Added sugars prime the brain to crave sweets

Worldwide obesity has nearly tripled since 1975, according to the World Health Organization (WHO). In the U.S., the issue of obesity threatens the health of both adults and children. With more than one third of U.S. adults living with obesity, they are at risk for certain preventable diseases such as heart disease, stroke and type 2 diabetes. 


Brain electrical activity translated into images

The idea of “mind-reading” has commonly been associated with magic or the supernatural. However, research done at a lab in the University of Toronto Scarborough (U of T Scarborough) recently took a significant stride forward in achieving this possibility.

Induced pluripotent stem cells (iPSCs) are similar to cancer cells and may be developed as a new treatment target.

Stem cells can be used as cancer treatment

Last week, researchers at the Stanford University School of Medicine published a study detailing how injecting pluripotent stem cells into the body may train the immune system to attack or even prevent cancer, thereby acting as a cancer vaccine.

Hopkins researchers found that cockroaches’ mobility patterns have practical robotic applications.

Cockroaches can be used to model robot locomotion

With this current period of rapid technological advances, it is no surprise that scientists and engineers all over the world are investing ample time and effort into improvements in robotic technology. Many believe that advances in this field will revolutionize the way people live in the next few decades.

More women have been taking ADHD medications before knowing they are pregnant.

More women are receiving ADHD prescriptions

The Centers for Disease Control (CDC) recently reported that the number of attention-deficit/hyperactivity disorder (ADHD) medicine prescriptions for women increased nearly fivefold from 2003 to 2015. Fifteen million adults in the United States have currently been diagnosed with the disorder. 


Coalition studies where science PhDs find work

In December of 2017, Hopkins announced it would be part of a coalition of 10 universities and research institutions working to release data on PhD and postdoctoral scholars’ admissions, demographics and career prospects.

The Tesla Roadster was launched with a mannequin astronaut at the Kennedy Space Center this past month.

What is to become of the Falcon Heavy rocket?

Earlier this month, SpaceX dominated headlines with the launch of its Falcon Heavy rocket.  Among the many interesting aspects of the monumental launch, the rocket’s payload stood out. Painted a shade of red named “midnight cherry,” the personal Tesla Roadster of SpaceX CEO Elon Musk was aboard the rocket when it lifted off.

Ward’s discovery shows that air dryers can spread as much as 1,300 times more germ particles than paper towels.

Do hand dryers transfer colonies of bacteria?

In today’s age of health fads and an increasing obsession with cleanliness, people have naturally evolved a public fixation on organic goods and detox juices. However, this trend has also provoked further awareness of the dirtiness of everyday appliances and objects.


The search for life on one of Saturn's moons

The eighth planet from the sun, Saturn, with its giant rings, is thought to be the most dazzling to picture. However, perhaps it is not the gas giant that should intrigue us but rather the rocky moons that orbit it.

The study showed no association between the occurance of full moons and earthquakes.

Despite myth, full moons don't trigger earthquakes

From werewolves, to crime and chaos, to the triggering of childbirth, there are many superstitions about the power of a full moon. While most of these superstitions can easily be dismissed as mere folklore, one superstition has held strong. Namely, popular belief has it that full moons can cause earthquakes.

Bennett’s discoveries built upon existing knowledge of the decades-old Big Bang theory.

Hopkins astrophysicist studies the Big Bang

Staring up at the heavens is something all humans, whether a thousand years ago or today, have done. Bloomberg Distinguished Professor Charles Bennett, an experimental cosmologist and recent recipient of the Breakthrough Prize, looks at space with the same fascination, harnessing the power of science and engineering to understand the universe’s deepest secrets.
