New group of stars discovered in our Milky Way

An astronomer from the Liverpool John Moores University (LJMU) Astrophysics Research Institute has found a new group of stars within our Milky Way Galaxy. The implications of this discovery could be enormous, as this sheds light on the early stages of the formation of the Milky Way Galaxy.

Chromosomes (the dense, purple clumps) may contain less DNA than previously thought.

DNA might make up only half of chromosomes

In a recent study published in the journal Molecular Cell, scientists discovered that DNA may make up only about half of the material found in chromosomes. In fact, up to 47 percent of a chromosome’s makeup may consist of a sheath, or a protective structure, surrounding DNA.

Intrafasicular multielectrode stimulation can help stimulate fatigue-resistant muscles.

Multielectrode stimulation can treat paralysis

Imagine yourself sitting comfortably in a car, gazing through the window at the oak trees gradually coming into sight and then vanishing quickly in a blur as the wheels continue in its steady, rolling motion. A flash of light blinds your eyes momentarily, fear immediately disperses across your entire body. The airbag in front bursts out shortly, and a huge mass crashes into your door.

Currently, trucks use diesel fuel, which is harmful for the environment.

New truck can run on hydrogen fuel cells

The Nikola Motor Company is developing a Class 8 truck, the Nikola One, that comes equipped with hydrogen fuel cell technology. Class 8 trucks are more commonly known as 18-wheelers, or semi-trucks, and have traditionally used diesel fuel as a form of energy.

HIV tests can be performed on a USB stick

Scientists at the Imperial College London and DNA Electronics, a U.K. biotech firm, have developed a new device that could change the way doctors and patients monitor HIV levels in the bloodstream.

Mental health disorders can lead to physical diseases in teenagers.

Mental disorders tied to specific physical diseases

Scientists have known for a while that mental disorders are often observed in conjunction with physical diseases. Previous studies have primarily focused on how the two are associated in adult populations. Researchers at the University of Basel and Ruhr-University Bochum studied young individuals and are beginning to link specific mental disorders to certain physical ailments in younger populations.

An asteroid that hit the Earth 66 million years ago may have liquefied Earth’s surface.

Pre-historic asteroid liquefied Earth’s surface

Around 66 million years ago, an asteroid hit the surface of Earth and drastically changed the Earth’s geological landscape. While this asteroid is widely believed to have wiped out the entire dinosaur population that once roamed the planet, scientists now theorize that the asteroid could also have momentarily liquefied the surface of the Earth.

Calciprotein particles lead to breakdown of connective tissue, which in turn can cause premature births.

Preterm birth linked to calciprotein formation

According to the World Health Organization (WHO), approximately 15 million babies are born preterm each year. Nearly a million babies die due to preterm birth complications, making preterm birth a leading cause of child death. On top of that, survivors of preterm births often develop learning, visual or auditory disabilities.

On Monday Nov. 14, the moon was the closest it had been to Earth since the year 1948.

The science behind Monday night’s supermoon

When you looked up into the sky this past Monday, Nov. 14, did you notice anything particularly strange? Perhaps the moon looked a lot bigger than usual? In fact,  scientists predicted that our moon was its largest relative to Earth in almost 69 years. Informally, astronomers and scientists alike have coined the name “beaver moon” for this astronomical wonder that lit up the sky.
