Nanoworms and rods are the most effective drug delivery vessels so far

Nanoparticles come in many shapes and sizes, including spheres, chains, reefs, and boxes, and more. When it comes to drug delivery, however, rods and worms are the most effective forms, according to a new study published in the journal Nature Nanotechnology.

Though the field of medical nanotech is still in its infancy, nanoparticles are already being used by doctors to overcome biological barriers, navigate cellular environments, and deliver anticancer drugs and vaccines deep into our bodies.

HIV researchers edge closer to a cure

Most recent news on the fight against HIV has focused on preventative medicine and suppression, but British scientists might be inching toward an honest-to-goodness cure. A 44-year-old social worker in London appears to be completely free of the virus after undergoing an experimental "kick and kill" treatment as part of a trial. The patient first took a vaccine to help his immune system detect infected cells, and then took Vorinostat to activate dormant infected cells that normally don't get caught.

NASA Finds More Evidence of Water Plumes on Jupiter’s Moon Europa

Last week, NASA announced its scientists had found “surprising activity” on Jupiter’s moon Europa. And, just like you’d expect, the space-dork corner of the Internet whipped itself into a frenzy. Because that kind of vague statement can only mean they found aliens, right? Well, not really. But some people are still convinced, even after NASA tried to walk back its blatant nerd-baiting by tweeting that it was definitely not aliens.

Quantum teleportation over 7 kilometres of cables smashes record

A new world record for quantum teleportation has been set, bringing quantum communication networks that can stretch between cities a step closer. Two independent teams have transferred quantum information over several kilometres of fibre optic networks.

Being able to establish teleportation over long distances is a crucial step towards exchanging quantum cryptographic keys needed for encoding data sent over the fibres.

China Confirms Its Space Station Is Falling Back to Earth

In a press conference on Wednesday, Chinese officials appear to have confirmed what many observers have long suspected: that China is no longer in control of its space station.

China's Tiangong-1 space station has been orbiting the planet for about 5 years now, but recently it was decommissioned and the Chinese astronauts returned to the surface. In a press conference last week, China announced that the space station would be falling back to earth at some point in late 2017.

Doing exercise may counteract some of alcohol’s deadly effects

It’s good news for those equally at home on a treadmill or at a bar. Regular exercise seems to cancel out some of the risk of death that is linked to alcohol.

High alcohol intake is associated with fatal heart disease, stroke, and at least seven types of cancer.

An analysis of people over the age of 40 has found that people who do the recommended amount of physical activity a week – 150 minutes of aerobic exercising – but drink more than the UK weekly recommended limit are less likely to die than people who drink the same amount but exercise less.

Zika vaccine trials begin – but fears remain over virus’s impact

There’s finally some progress in the fight against Zika. A vaccine is being given to 160 people in Zika-hit Puerto Rico, and a preliminary study has identified two existing drugs that seem to protect human brain cells from the virus.

The vaccine, developed by Inovio Pharmaceuticals, contains a synthetic DNA fragment similar to one in the virus itself. The company hopes that people who receive it will develop immune protection against Zika.

Astronomers Don’t Think That So-Called SETI Signal Is Aliens

This weekend, a group of astronomers made many, many headlines after giving a presentation about “a strong signal in the direction of HD164595.” HD164595 is a Sun-like star 94 light-years away, and with the RATAN-600 radio telescope in Zelenchukskaya, Russia, pointed in its direction, the astronomers picked up a blast of radio waves about 4.5 times stronger than background static. Maybe aliens? they suggested. We should investigate.
