Diamonds found to be made mostly of the seafloor, pressure-cooked to perfection

When Old Rose dropped the diamond necklace into the ocean at the end of Titanic, it turns out she was probably just returning it to where it originally came from. Researchers in Australia and Germany have found that many diamonds begin life a… Continue reading Diamonds found to be made mostly of the seafloor, pressure-cooked to perfection→

Scientists discover why a promising cancer drug failed in clinical trials – and how to fix it

As promising as some treatments are in lab tests, unfortunately they don’t always meet hopes when translated to the real world. Now, scientists at Whitehead Institute for Biomedical Research have investigated a class of cancer drugs that fail… Continue reading Scientists discover why a promising cancer drug failed in clinical trials – and how to fix it→

Close encounter with alien star could explain ’Oumuamua, debunk Planet Nine

Our solar system has several “belts” of rocky planetesimals that are essentially the crumbs left over from the formation of the planets and moons. But new research suggests some of them could actually be alien, captured during close flybys wi… Continue reading Close encounter with alien star could explain ’Oumuamua, debunk Planet Nine→

Self-powered micro-submarines sink and swim to deliver drugs in the body

It’s entirely possible that micro-machines could one day be delivering drugs inside the body, with many designs proposed in recent years. The latest comes from the University of New South Wales (UNSW), which gets around under its own power us… Continue reading Self-powered micro-submarines sink and swim to deliver drugs in the body→

Caltech reactor could convert CO2 into breathable oxygen for space trips

Although oxygen is common throughout the cosmos, most of it isn’t in the form that we as humans need to breathe – molecular oxygen, or O2. Now, researchers at Caltech claim to have created a reactor that can turn carbon dioxide into molecular… Continue reading Caltech reactor could convert CO2 into breathable oxygen for space trips→

Gold-mining fungi could guide human prospectors

Shiny, pretty and useful in electronics, gold has been prized by humans for millennia, but we’re not the only ones out there prospecting. Scientists from Australia’s CSIRO have now found a fungus species that mines for gold and even decorates… Continue reading Gold-mining fungi could guide human prospectors→

Earth-buzzing comet found carrying "ocean-like" water

Earth is a famously wet planet, but where all that water came from in the first place remains a mystery. The most commonly-accepted theory is that comets and asteroids delivered it via impacts during the early days of Earth, and now a NASA st… Continue reading Earth-buzzing comet found carrying "ocean-like" water→

New superconductivity record edges closer to room temperature

No matter how good a material is at conducting electricity, there’s usually some resistance – unless you use superconductive materials. Since they can conduct electricity with absolutely no loss, they could be revolutionary if not for one lit… Continue reading New superconductivity record edges closer to room temperature→

Drug-resistant infections could be starved of nutrients using existing medicines

Microorganisms like bacteria and fungi are increasingly becoming resistant to our best drugs, which is hurtling us towards a terrifying future where once-easily-treated infections become potentially life-threatening again. But now researchers… Continue reading Drug-resistant infections could be starved of nutrients using existing medicines→

New algorithm digs up 18 Earth-like exoplanets from old Kepler data

So far almost 4,000 planets have been discovered orbiting stars other than the Sun, and that tally is constantly growing. Now another 18 exoplanets have been added to the haul, but the difference this time is that all of them are roughly Eart… Continue reading New algorithm digs up 18 Earth-like exoplanets from old Kepler data→
