Evidence for more recent clay formation on Mars discovered

The lion's share of the clay deposits found on Mars thus far have turned up in terrains that date back to the earliest Martian epoch, known as the Noachian period. Clays also tend to be found in and around large impact craters, where material from deep below the surface has been excavated. Scientists have generally assumed that the clays found at impact sites probably formed in the ancient Noachian, became buried over time, and then were brought back to the surface by the impact.

Bone cancer researchers discover how to block, potentially treat osteosarcoma

The proof-of-concept findings, published online in Science Translational Medicine, establish the importance and function of the bone master regulator, a protein known as RANKL, in bone cancer and set the stage to develop rationalized targeted therapy for patients, says principal investigator Rama Khokha, Senior Scientist at the Princess Margaret Cancer Centre. Dr. Khokha is also a Professor in the departments of Medical Biophysics and Laboratory Medicine and Pathobiology at the University of Toronto.

Earth May Spin Faster as Glaciers Melt

Melting ice triggered by global warming may make Earth whirl faster than before and could shift the axis on which the planet spins, researchers say.

What is Protien?

Protein is a macronutrient that is essential to building muscle mass. It is commonly found in animal products, though is also present in other sources, such as nuts and legumes. 

There are three macronutrients: protein, fats and carbohydrates. Macronutrients provide calories, or energy. The body requires large amounts of macronutrients to sustain life, hence the term “macro,” according to the University of Illinois McKinley Health Center. Each gram of protein contains 4 calories. Protein makes up about 15 percent of a person’s body weight.

Chemically, protein is composed of amino acids, which are organic compounds made of carbon, hydrogen, nitrogen, oxygen or sulfur. Amino acids are the building blocks of proteins, and proteins are the building blocks of muscle mass, according to the National Institutes of Health (NIH).
