All-perovskite tandem solar cell boasts high efficiency, record voltage

Engineers have developed a new solar cell with a record voltage and (arguably) a record efficiency for its kind. The all-perovskite tandem solar cell uses two layers of perovskite that tap into different wavelengths of light, plus a special surface tre… Continue reading All-perovskite tandem solar cell boasts high efficiency, record voltage

Implantable pump drip-feeds chemotherapy directly into brain tumors

Researchers at Columbia University and New York Presbyterian have developed an implantable pump that can continuously deliver chemotherapy drugs directly into the brain to fight hard-to-treat cancer. In a phase 1b trial, patients were able to undergo t… Continue reading Implantable pump drip-feeds chemotherapy directly into brain tumors

3D microscope video tracks virus zipping around in real time

Scientists at Duke University have created a real-time video that captures the frantic movements of a single virus as it tries to infect a cell. The video shows a part of the process that’s normally hard to see.Continue ReadingCategory: Biology, Scienc… Continue reading 3D microscope video tracks virus zipping around in real time

Stem cells (and mini brains) grown from critically endangered rhinos

The Sumatran rhino is critically endangered and difficult to breed. But now, researchers have created induced pluripotent stem cells (iPSCs) from the genetic material of a male, potentially providing new ways to help conservation efforts. They even use… Continue reading Stem cells (and mini brains) grown from critically endangered rhinos

Earliest evidence of humans cooking with fire dates back 780,000 years

An artist's impression of early humans cooking fish at Lake Hula in what is now Israel

Scientists have discovered the earliest evidence of humans cooking food through the controlled use of fire, dating to almost 800,000 years ago. An archeological site in Israel contains fish remains that, on closer examination, show clear signs of having been cooked.

Nanoparticle backpacks help probiotics fight inflammatory bowel disease

Probiotic bacteria can’t help improve gut health if they don’t survive the trip to the intestines. Scientists have now kitted out good bugs with protective armor and backpacks loaded with molecules that can help them treat inflammatory bowel diseases (… Continue reading Nanoparticle backpacks help probiotics fight inflammatory bowel disease

Speed record shattered for data transmission over standard optical fiber

Engineers have set a new speed record for data transmission through a standard diameter optical fiber. By beaming 55 “modes” of signals down a single-core optical fiber, the team was able to transmit at a data rate of 1.53 petabits per second (Pbit/s)…. Continue reading Speed record shattered for data transmission over standard optical fiber

“Hybrid” immune system reboot leads to functional diabetes cure in mice

Researchers at Stanford University have developed a functional cure for diabetes in mice, by creating a kind of hybrid immune system. Treated animals were able to manage their blood glucose levels for the duration of the trial, without needing the immu… Continue reading “Hybrid” immune system reboot leads to functional diabetes cure in mice

IBM reveals Osprey, the world’s most powerful quantum computer

IBM has unveiled the most powerful quantum processor in the world – the Osprey, which boasts a massive 433 quantum bits (qubits). The new chip headlines a raft of advances in quantum computers that the company has announced, as it prepares for a massiv… Continue reading IBM reveals Osprey, the world’s most powerful quantum computer

Scientists identify neurons that help paralyzed patients walk again

Electrical stimulation of the spine can help paralyzed people walk again, with promising results shown in clinical trials. Now, scientists have identified the specific neurons being stimulated, and found that patients can still walk even after the elec… Continue reading Scientists identify neurons that help paralyzed patients walk again
