Physical activity that makes you puff and sweat is key to avoiding an early death, a large Australian study of middle-aged and older adults has found.

The researchers followed 204,542 people for more than six years, and compared those who engaged in only moderate activity (such as gentle swimming, social tennis, or household chores) with those who included at least some vigorous activity (such as jogging, aerobics or competitive tennis).

They found that the risk of mortality for those who included some vigorous activity was 9 to 13 per cent lower, compared with those who only undertook moderate activity.

^lol, jk!! :)

In many casual discussions of language and the internet, it’s not uncommon to hear about how such “textspeak ruins language” – how technology has made everybody lazy with their speech and writing. Major media outlets such as the LA Times, the BBC and The Daily Mail have all bemoaned the ways in which people communicate through technology.

Researchers have made a significant breakthrough in the development of synthetic pathways that will enable renewable biosynthesis of the gas propane. 

Natural metabolic pathways for the renewable biosynthesis of propane do not exist but scientists at the Manchester Institute of Biotechnology (MIB), Imperial College and University of Turku have developed an alternative microbial biosynthetic pathway to produce renewable propane.

Not all exoplanets are going to be habitable, many will be just the opposite. Astronomers have measured the temperature of the atmosphere of an exoplanet with unequaled precision and determined we won't be vacationing there any time soon. By crossing two approaches, using the HARPS spectrometer and a new way of interpreting sodium lines, researchers have been able to conclude that exoplanet HD 189733b is showing infernal atmospheric conditions, with wind speeds of more than 1,000 kilometers per hour and a temperature 3,000 degrees. 

Researchers have discovered how nerve cells adjust to low energy environments during the brain's growth process, which may one day help find treatments for nerve cell damage and neurodegenerative disorders such as Alzheimer's and Parkinson's diseases.

Neurons in the brain have extraordinarily high energy demands due to complex dendrites that expand to high volume and surface areas. It is also known that neurons are the first to die from restriction of blood supply to tissues, causing a shortage of oxygen and glucose needed for cellular metabolism.

Human norovirus can cause an immune response in dogs so it leads to obvious concern over whether or not dogs can transmit it to other people.

Norovirus, which causes vomiting and diarrhea, is extremely contagious among humans. It infects 19-21 million Americans annually - more than six percent of the US population - according to the CDC. Those infections may result in as many as 71,000 hospitalizations, and 800 deaths.
