Scientists make breakthrough on antibiotic-resistant bacteria

Bacteria can naturally develop antibiotic resistance, but it’s thought that a spike in these strains is caused by overuse of antibiotics, as well as misuse by patients. But a team of researchers was able to show that a new class of antibiotics was able to break through that protection.

Scientists will try to create matter from light

Scientists at Osaka University and UC San Diego have developed an experiment they believe could turn photons into matter using lasers.

Getting antibody cells to make life-saving enzymes instead

The problem: Inherited metabolic disorders happen when a defective gene creates an enzyme deficiency in the body. There are a lot of them, and some can be treated by managing diet, but others require regular enzyme infusions for a patient’s entire life.

Skipping surgery by 3D printing bones and heart tissue

The problem: One way scientists have tried to avoid cutting people open for surgery is by injecting a photo-sensitive ink that can harden into replacement tissues, but light can’t penetrate very far through skin and organs.

The solution: Researchers at Duke University and Harvard Medical School have developed an ink that hardens when vibrated by sound waves

Japan’s wooden satellites could fix the problem of space junk

Between decommissioned satellites and bits shed from spacecraft, humans leave a lot of metal in the atmosphere. That reflective junk creates light pollution, bashes into the International Space Station, and — when it falls out of orbit and into the atmosphere — burns up into millions of tiny metallic particles. 

We may have figured out how to grow plants on the moon

It’s not quite Matt Damon starting a potato field on Mars, but recent experiments could help make moon farms a real possibility.

Science has a fake paper problem

Back in March, the discovery of a new superconductor opened up a world of possibilities, from phone batteries that last days to hyper-efficient energy grids. Except it was all a lie. 

What happened: This week, Nature retracted a high-profile paper claiming the discovery of a superconductor that worked at room temperature. Superconductors — which can transmit electricity without energy loss — blow away standard metals, like copper and aluminum.

Halloween treats probably won’t give you lead poisoning, but watch that hot chocolate

New research is putting the harmful metal content of chocolate under the microscope again, but don’t go tossing the kids’ trick-or-treat haul just yet.

What happened: Watchdog group Consumer Reports tested dozens of chocolate products for lead and cadmium, finding that almost one-third had dangerous levels.

New space rocks just dropped

Unlike many of us coming home from holiday, NASA remembered to bring back souvenirs from its latest trip.

Driving the news: The largest asteroid sample ever brought back to Earth touched down Sunday morning when NASA’s OSIRIS-REx capsule returned from a 7-year trip—a mission Canada played a crucial role in. 

Researchers crack the Y chromosome code

A scientific breakthrough could shed light on some of the biggest threats facing men's health. 

Driving the news: According to new research published in the Journal of Nature, scientists have fully sequenced the DNA of the Y chromosome.
