Researchers have discovered that carbonaceous chondrites, a class of meteorites, incorporated hydrated minerals along with organic material from the protoplanetary disk before the formation of planets. Scientists from the study published in the journal Space Science Reviews note that these meteorites played “an important role in the primordial Earth’s water enrichment” because they facilitated the transportation of volatile elements that were accumulated on the external regions of the so-called protoplanetary disk from which planets were formed more than 4.500 years ago. Earth was formed in an environment close to the Sun, very much reduced due to the relative lack of oxygen.

Carbonaceous chondrites come fro...

Researchers from the University of Vienna, who have found a river of stars, a stellar stream in astronomical parlance, covering most of the southern sky. The stream is relatively nearby and contains at least 4000 stars that have been moving together in space since they formed, about 1 billion years ago...

Elderly to feel fitter, faster and stronger. Researchers from The University of Texas Medical Branch at Galveston have developed a promising drug that has proven to significantly increase muscle size, strength and metabolic state in aged mice, according to a study just published in Biochemical Pharmacology.

As we age, our bodies increasingly lose the ability to repair and rebuild degenerating skeletal muscles. Beginning around age 35, muscle mass, strength and function continually decline as we get older. This can dramatically limit the ability of older adults to live fully active and independent lives.

“We identified a protein in m...

Active, middle-aged men able to complete more than 40 push-ups had a significantly lower risk of cardiovascular disease (CVD) outcomes – including diagnoses of coronary artery disease and major events such as heart failure – during 10 years of follow-up compared with those who were able to do less than 10 push-ups during the baseline exam.

“Our findings provide evidence that push-up capacity could be an easy, no-cost method to help assess cardiovascular disease risk in almos...
