Red Meat Allergy Linked to Heart Disease

June 21, 2018

For years, science has linked the saturated fats that can be found in red meats to cardiovascular disease. Now a new study published in the American Heart Association’s journal Arteriosclerosis, Thrombosis, and Vascular Biology suggest that sensitivity to an allergen found in red meat may also contribute to the buildup of arterial plaque in some people. […]

Pre-Solar System Dust Found in the Atmosphere

June 15, 2018

A research team led by the University of Hawai’i at Mānoa’s School of Ocean and Earth Science and Technology say they have discovered the remains of the formation of the solar system in some interstellar dust. The dust particles, which were gathered in Earth’s atmosphere by NASA aircraft, are thought to have been cast off from […]

Sunlight Can Hinder Oil Spill Cleanup Efforts

April 27, 2018

A 2003 report by the National Research Council of the National Academies of Sciences estimated that more than 1.3 million metric tons of petroleum make it into the sea each year. Among the tools used to lessen the impact of oil spills are chemical dispersants which break up the floating oil into small droplets. But […]

New DNA Structure Observed in a Living Cell

April 25, 2018

When you visualize a DNA structure, you probably think about the well-known ‘double helix’ that was revealed in 1953 by Cambridge University scientists James Watson and Francis Crick. The duo, along with physicist and molecular biologist Maurice Wilkins, won the 1962 Nobel Prize in Physiology or Medicine for what the Nobel Foundation described as their […]

New Device Will Tell You if Your Food is Safe to Eat

April 6, 2018

Have you ever wanted some way to tell whether meat and other foods are safe to consume? A group of mechanical, chemical engineers and biochemists at Canada’s McMaster University may have come up with such a solution. They’ve developed a new transparent test patch, named “Sentinel Wrap”, that can tell you if the food you’re […]

Drinking Wine Could Aid Oral Health

March 1, 2018

Recent reports have suggested that drinking a glass of wine may be beneficial to your health. Researchers have found that wine has a concentration of a type of antioxidant called polyphenols that can be good for heart, brain, and muscle health. Some studies have also found that it might even be able to help fight […]

Einstein Proven Correct; Gravitational Waves Detected; Super Hot Planet

June 8, 2017

Einstein Theory Confirmed Again In his 1915 Theory of General Relativity, physicist Albert Einstein proposed that mass can bend space time. And he predicted that when a distant star’s light passed by a large object en route to the observer, the object’s gravity can bend and brighten the starlight like a magnifying lens. This effect, called […]

Insight Into Planetary Evolution – Dark Matter Rare in Old Galaxies

March 17, 2017

Scientists Gain New Insight into Planetary Evolution Scientists recently gained new insight into the evolution of planet formation by creating and studying a model of a fairly young solar system 300 light years from Earth. The nearly 13 million year-old planetary system circles a star known as HD 106906. The system features a surrounding planet […]

Odd Feature from Galactic Collision; Crack in the Magnetosphere; Smartphones Make Us Trust Less?

November 5, 2016

Galactic Fender-Bender Produces Eye-Lid Shaped Feature A team of astronomers say what started as a fender-bender between two galaxies has sent a torrent of stars and gas crashing through the center of one, which then produced a rare eyelid shaped star formation. Working with the Atacama Large Millimeter/submillimeter Array (ALMA), in Chile, the astronomers identified […]

Light Not Shock Restarts Heart; Bees Nest in Sandstone; 5 Second Rule

September 14, 2016

Using Light Instead of Electric Shock to Restart a Heart A defibrillator is a device used to restore the normal operation of a heart after a life-threatening cardiac episode such as dysrhythmias and ventricular fibrillation. The machine delivers a powerful electric shock that stops the heart and allows it to reset itself to function normally […]
