Nerve study on pain-immune mole-rats could inspire new pain relief for humans

They’re not much to look at, but mole-rats are pretty amazing animals. Among a range of other biological oddities, these weird little rodents have a remarkable resistance to pain that’s not seen in other mammals, and now researchers have a be… Continue reading Nerve study on pain-immune mole-rats could inspire new pain relief for humans

Curiosity strikes clay in new samples, further proving Mars' watery past

Curiosity took this selfie on May 12. The two drill holes in the clay-bearing region can ...

NASA’s Curiosity rover has begun investigating one of the most interesting regions so far on its seven-year journey. Scientists call the area the “clay-bearing unit,” and sure enough, that name has turned out to be very apt. After drilling two new samples last month, the rover has finally confirmed high amounts of clay minerals, providing further proof that ancient Mars was once much wetter.

How the gut overrides the throat in telling the brain whether it's thirsty

Researchers have found two pathways that tell the brain when the body has had enough water

Feeling thirsty is a natural bodily function to get you to drink some water – but why does the feeling go away so quickly after downing a glass? Shouldn’t it take a bit of time for the water to be absorbed? Strangely enough, the mechanisms behind thirst and satiation are somewhat of a mystery to science. So now researchers from Caltech have investigated and found two connections between body and brain that control the process.

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
