An end to the AIDS epidemic could be in sight after a landmark study found men whose HIV infection was fully suppressed by antiretroviral drugs had no chance of infecting their partner.

The success of the medicine means that if everyone with HIV were fully treated, there would be no further infections.

Among nearly 1,000 male couples across Europe where one partner with HIV was receiving treatment to suppress the virus, there were no cases of transmission of the infection to the HIV-negative partner during sex without a condom. Although 15 men were infected with HIV during the eight-year study, DNA testing proved that was through sex with someone other than their partner who was not on treatment.

Given the chance, there are very few of us who wouldn’t want to slow down the aging process. Chasing that fountain of youth is a major branch of medical science at the moment, and a hardy little worm known as C. elegans is probably the most prolific test subject. Now, a team at Scripps Research has found that blocking a particular enzyme can extend the lifespan of these worms by almost half again.

The first-of-its-kind event is giving scientists a vast cache of new information about the dynamic universe.

Black hole mergers have become nearly commonplace, but this is still a “first.”

How far is far? And, how do you know when you get there? In 1995, astronomers decided to use Hubble to conduct a bold and daring experiment to address this puzzle. For 10 consecutive days, Hubble stared at one tiny, seemingly empty patch of sky for 1 million seconds.

The gamble of precious telescope time paid off. Hubble captured the feeble glow of myriad never-before-seen galaxies. Many of the galaxies are so far away it has taken billions of years for their light to reach us. Therefore, the view is like looking down a “time corridor,” where galaxies can be seen as they looked billions of years ago. Hubble became astronomy’s ultimate time machine.

The resulting landmark image is called the Hubble Deep Field. At the time, the image won the gold medal for being the farthest peek into the universe ever made. Its stunning success encouraged astronomers to pursue a series of Hubble deep-field surveys. The succeeding surveys uncovered more galaxies at greater distance from Earth, thanks to new cameras installed on Hubble during astronaut servicing missions. The cameras increased the telescope’s power to look even deeper into the universe.

Today, we want to spotlight a new publication that charts the senescence-associated secretory phenotype (SASP), which consists of the various secreted signals given out by senescent cells during aging.

Senescent cells and the SASP

As we get older, an increasing number of our cells enter into a state known as senescence. They cease dividing and supporting the tissues and organs of which they are part and, instead, secrete a range of harmful chemical signals. This cocktail of harmful signals is known as the senescence-associated secretory phenotype (SASP).

When 5G mobile services start to roll out worldwide from next year, smart cities such as Hangzhou are expected to get smarter as the next-generation wireless technology helps industries realise the full potential of the internet of things (IoT).

The stakes are high for industries around the world, as global spending on the internet of things is forecast to exceed US$1 trillion in 2022, up from an estimated US$745 billion this year.

LIVE ROCKET LAUNCH! Tune in to see us send tons of research and supplies to the International Space Station aboard a SpaceX Dragon spacecraft. Liftoff of the Falcon 9 rocket is slated for no earlier than 3:11 a.m. EDT, Friday, May 3. from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. Don’t miss the countdown to liftoff!

Humanity must make a giant leap in space exploration and begin the process of migrating to Mars, argues Apollo astronaut Buzz Aldrin.

The 89-year-old said a ‘great migration’ is necessary not only for the sake of exploration but for the ongoing survival of the human race.
