Just how old is the Universe? Astrophysicists have been debating this question for decades. In recent years, new scientific measurements have suggested the universe may be hundreds of millions of years younger than its previously estimated age of approximately 13.8 billions of years.


Now new research published in a series of papers by an international team of astrophysicists, including Neelima Sehgal, PhD, from Stony Brook University, suggest the universe is about 13.8 billion years old. By using observations from the Atacama Cosmology Telescope (ACT) in Chile, their findings match the measurements of the Planck satellite data of the same ancient light.

Virginia Tech researchers have proven that a single gene can convert female Aedes aegypti mosquitoes into fertile male mosquitoes and identified a gene needed for male mosquito flight.


Male mosquitoes do not bite and are unable to transmit pathogens to humans. Female mosquitoes, on the other hand, are able to bite.

Female Aedes aegypti mosquitoes require blood to produce eggs, making them the prime carriers of the pathogens that cause Zika and dengue fever in humans.

As the coronavirus pandemic continues, it’s becoming clear that, for the foreseeable future at least, face masks are here to stay. They’re mandatory on public transport, they’re compulsory in shops in Scotland, and from July 24, shoppers will need to wear them in England or face a £100 fine.

But as we all don our masks as evidence in favour of the garment’s effectiveness in curbing the spread of coronavirus mounts, obscuring part of our face is having a detrimental effect on how some of us communicate with each other.

After China imposed a restrictive national security law on Hong Kong, tech companies find themselves at a crossroads. Giants like Google and Facebook stopped responding to requests for user data in the city, but they may eventually have to pull out altogether.

One marquee name to exit Hong Kong already is TikTok, which remains eager to prove its distance from its China-based parent company. TikTok also found itself embroiled in a confusing episode on Friday, when an internal Amazon email indicated that the company was ordering employees to remove the app from their phones; hours later, Amazon stated that the email was sent in error. Hate it when the drafts go live, especially when they cause an international furor.

New observations could challenge previous theories of how the Moon was formed


Life on Earth would not be possible without the Moon; it keeps our planet’s axis of rotation stable, which controls seasons and regulates our climate.  However, there has been considerable debate over how the Moon was formed. The popular hypothesis contends that the Moon was formed by a Mars-sized body colliding with Earth’s upper crust which is poor in metals. But new research suggests the Moon’s subsurface is more metal-rich than previously thought, providing new insights that could challenge our understanding of that process.
