Why malaria-spreading mosquitoes are so hard to kill – and how scientists found a way to kill them without impacting the environment or other living creatures.

Almost half of the people in the world live in an area where malaria parasites can infect and kill them. Malaria parasites enter the body via a mosquito. The parasites travel to the liver where they it can remain undetected for as long as a year. While in the liver, malaria parasites develop and release toxic substances that infect red blood cells. These toxins are dumped into the bloodstream and distributed throughout the body. This is when symptoms begin to show. Symptoms of someone infected with malaria include fever, chills, headache, vomiting, sweating, cough, and chest, stomach, and muscle pain. Often these symptoms appear in waves or “attacks” that come and go. Fighting the mosquitoes that transfer malaria to humans has been difficult. Mosquitoes have…

Let’s be #ClimateHeroes! Here’s what you can do to battle climate change and be the generation that literally saves the world!

Science will help reverse climate damage but there are still lots of things you can do to battle climate change while we wait. Together we can beat climate change and become the generation that literally saves the world! Let's become #ClimateHeroes! Here's how: Can we beat climate change? Humans have overcome insurmountable odds in the past. There's no reason to believe we can't do it again and crush the climate change problem. It will of course, require sacrifice, money, and hard work. The single most important goal will be to limit the use of fossil fuels such as oil, carbon, and natural gas and replace them with renewable energy sources such as wind generation and solar energy. Here are other ways you can help battle…

NASA announces its next mission “Dragonfly” – will explore Saturn’s moon Titan with a drone-like lander.

As part of NASA’s New Frontiers program, they have selected their next mission – a drone-like lander that will explore the surface of Saturn’s moon Titan. The Dragonfly mission will send a dual-quadcopter to the surface of Titan. About every 16 days it will fly tens of miles above the surface for about an hour before stopping to rest and recharge. During these “hops”, Dragonfly will sample the moon’s surface material and observe its weather patterns. The Huygens probe (carried by Cassini) was the first to give us a good view of the moon’s surface. It was found that Titan had a thick atmosphere and liquid methane coverings its surface. This interested NASA scientists who have been longing to send a lander to the moon…

Listen up. Scientist create sound so loud, it instantly boils water

Bang your head! Scientists at Stanford University created a sound that measures a whopping 270 decibels. The sound was created underwater and is believed to be the limit of how loud a sound can be. Ready to put on a pair of earplugs and give the sound a listen? Not so fast. Scientists say earplugs would do no good. The sound is so loud, eardrums, heart, lungs, and other internal organs would instantly rupture.

For the first time, scientists have captured a picture of a black hole in space and it’s amazing!

Astronomers have done what was thought to be impossible – they captured the unseeable, a picture of a black hole, an object so dense, nothing, not even light, can escape it. The photo was taken by scientists at the Harvard-Smithsonian Center for Astrophysics. The picture of the black hole shows a lopsided ring of light surrounding a dark circle – the black hole itself. The black hole is in a galaxy known as Messier 87 in the constellation Virgo. The black hole is 55 million light years away from earth. That is so far, if you hopped a ride on the Space Shuttle, it would take you 20,450,000 years to reach it. Here's what messier 87 looks like through a telescope. To capture the image…

Why do grapes in a microwave burst into brilliant, violent, white flames? It’s plasma, baby!

Cut a grape in half but leave the skin of one side intact, Place the grape in the microwave and crank up the microwave radiation. Viola, the grape bursts into a brilliant, white-hot flame. The same effect occurs with two grapes in a microwave that touch each other. The flame you see is plasma – a hot mixture of electrons and electrically charged atoms, or ions. Scientists only recently discovered why the grapes burst into flames. They used to think grapes acted like antennas, collecting microwaves. Now they understand that grapes in a microwave act as resonators, not antennas. Like a musical instrument that resonant sound waves, a grape in a microwave resonates microwave radiation. In other words, the waves of radiation get trapped inside…

What plant is best for offsetting global warming and combating climate change?

Global warming, or “climate change” is a manmade catastrophe for our planet. It is mainly caused by our emissions of CO2 (carbon dioxide) which is created when we burn fuel in cars and power plants that generate electricity. In short, we pull substances rich with CO2 from deep inside the earth ( oil) and when burned, release CO2 and other gases into the air. The gases act like an insulating blanket around the planet which keeps heat from the Sun inside our atmosphere and thus warming the planet. The production of carbon dioxide and other “greenhouse gases” is further worsened by our purposeful destruction of trees. It is common for entire forests to be cleared for development of housing, shopping centers, and roads and highways.…

NASA launches fastest manmade object in history – Parker Solar Probe will travel more than 400,000 miles per hour and “touch” the Sun!

It hasn’t made it into the popular news channels much which is puzzling (and sad) because the device, and its mission, is so very, very cool. On August 12, 2018, NASA will launch the Parker Solar Probe, a car-sized spacecraft with a mission to examine the Sun’s corona. It’s no small feat and will require the probe maintain speeds of 430,000 miles per hour as it whirls around the sun. The Polar Solar Probe is an attempt to unravel some of the mystery around the Sun’s corona, that layer of hot plasma that floats millions of miles around the sun. The corona is the source of the Sun’s solar wind and is what causes the beautifully, colorful aurorae in the Earth’s magnetosphere. Parker's mission is…

NASA’s 20-year satellite-time-lapse of the planet shows a earth breathing as the climate changes

The geeks at NASA released a time-lapse photo revealing how our planet has changed over the past two decades.  The photos were taken from NASA satellites that continuously monitor populations of plant life on land and in the oceans.  The ocean color changes are caused by changing populations of phytoplankton (purple is low population numbers and yellow is high).  If it looks like the planet is breathing - well it is!  NASA stated: That's the Earth, that is it breathing every single day, changing with the seasons, responding to the sun, to the changing winds, ocean currents and temperatures. The space-based view of life allows scientists to monitor crop, forest and fisheries health around the globe. As NASA begins its third decade of measurements, these…

Natures way to spread plant life – birds, bees, and… goats in trees that spit seeds?

It’s not unusual to see birds in trees. Pigeons in trees are a common sight in New York City. In Texas, noisy finch crowd trees along scenic roadways. In Washington, , vultures loom in trees waiting the opportunity to swoop down on unassuming middle-class citizens. But in south-western Morocco, hungry goats perch with acrobat-like agility high above the ground eating fruit and leaves and spitting out seeds. Goats? In trees? Spitting seeds? Goats in the boughs of trees are a common site in dry, arid areas like Spain and Mexico where edible ground-plants are harder for the goats to find. But the goats in trees in Morocco tower above all others. Locals say it’s common for 10-20 goats at a time to climb argan trees…
