Scientists researching aging have found a new way to extend the lifespans of living organisms. By manipulating cells they were able to quadruple the lifespan of a worm. In human years this equates to an extension of around 400 to 500 years. The technology still requires much research before it can be used on humans.

The greenhouse gas HFC-23 was used to replace gases used in fridges, inhalers and air conditioners due to their ozone-depleting effects, but has instead contributed significantly to global warming, with India and China as the main emitters of HFC-23. Despite the two countries' governments reporting a reduction in HFC-23 use, researches have found its atmospheric concentration is increasing rapidly, contradicting reported figures from the Indian and Chinese governments.

Researchers at the Palomar Observatory in southern California have discovered the first ever Vatira asteroid, which is a rare kind of asteroid found in the interior of the Earth's orbit. While Vatira asteroids were theorized in 2012, no proof had been found until now. The asteroid has been named 2020 AV2, and orbits the Sun once every 151 days, staying between Mercury and Venus' orbits.

Physicists in US and Austria, have managed to observe billions upon billions of quantum entangled electrons flowing through the film of a quantum critical metal, YbRh2Si2. Measurements conducted, reveal that optical conductivity of the metallic films being cooled to a quantum critical point, marked the transition from one quantum phase to another. The findings suggest that quantum criticality can be used to study both quantum information and high-temperature superconductivity.

Since the moon has long been considered an area extremely inhospitable for life, scientists at the Southwest Research Institute in Boulder, Colorado have recommended that NASA should remove some restrictions designed to protect the moon from organic contamination, with the exception of the lunar south pole, where evidence of water ice still suggests its potential for explaining how life may have started on Earth.

Climate scientists are saying that the fires that are currently ravaging Australia could become normal due to climate change unless swift action is taken. Many have already established that climate change is one of the leading causes of the fires although the government and media have attempted to downplay its importance.

Jana Batovska, a microbiologist at the AgriBio Centre for AgriBioscience in Victoria, Australia, recently published her discovery of a new kind of insect-only alphavirus, which she has chosen to name the "Yada yada" virus, after a catchphrase from the popular 90s TV show Seinfeld. Batovska states she named it so because "yada yada" is used to indicate dull detail, and the virus is not particularly interesting or dangerous to humans.

Diego, a 100-year-old Galapagos giant tortoise, has been credited with single-handedly saving his species from extinction, from being one of only two surviving males to fathering almost 800 tortoisees in 50 years. Diego is estimated to be the ancestor of more than 40 percent of Galapagos giant tortoises alive today, and has recently been retired from his species-saving activity and released back into the wild.

A groundbreaking research led by forest ecologist Paulo Brando at the University of California, Irvine, has discovered that the spread of wildfires in the Amazon rainforest might do irreparable harm to its ability to absorb carbon dioxide, turning parts of the forest into carbon sources rather than sponges. Brando urgently recommends decreasing deforestation in the region to prevent such a drastic outcome.

A decade-long study led by comparative physiologist Timothy Clark at Deakin University in Geelong, Australia has challenged the long-held notion among marine biologists that rising levels of ocean acidification will disturb fish behavior. The research analysed individuals belonging to six distinct reef species and found no change in behavior for levels of acidification consistent with climate models for this century.

A research team led by James Rhoads, an astrophysicist at NASA's Goddard Space Flight Center, studied a trio of galaxies in the northern sky which are so are away that the light reaching Earth from them is only 680 million years old. Observation of the ancient galaxies has uncovered new evidence for why the early universe's hydrogen underwent ionization: it was due to the galaxies' high energy UV radiation.
