Nuclear fusion milestone creates "burning plasma" for the first time
January 26, 2022For the prospect of limitless, clean energy produced through nuclear fusion to become a reality, scientists need the reactions at the heart of the technology to become self-sustaining, and newly published research has edged them closer to that goal. -
Thermoelectric device wraps around hot pipes to generate electricity
January 24, 2022We've already heard about hoses that get wrapped around existing hot water pipes, using heat radiated from the pipe to heat water inside the hose. A new wrap-around device, however, uses that same pipe-heat to generate electricity. -
Quantum dots make for stabler, more efficient perovskite solar cells
January 20, 2022Perovskite solar cells have come a long way in a short time, but there’s still room for improvement. Engineers have now added a layer of quantum dots to the recipe, resulting in a more stable solar cell with near-record efficiency.

Two new studies join debate over presence of liquid water lake on Mars
January 27, 2022Recent studies reported the discovery of lakes of liquid water below the polar ice caps on Mars, but others later refuted the find. Fueling the debate are two new independent studies, which have reached opposite conclusions. -
Innovative chemical heating system keeps lunar landers warm at night
January 27, 2022With temperatures as cold as to -232 °C, the lunar night is not a friendly place for electronics. Space technology company Masten has developed a more efficient, safer system that uses chemical reactions to keep lander electronics warm until dawn. -
Discarded SpaceX rocket is on a collision course with the Moon
January 26, 2022Showing that space junk isn't a local problem, observations by amateur astronomers have determined that the upper stage of a SpaceX Falcon 9 rocket launched in 2015 will impact the Moon on March 4 at 12:25 GMT.

New technique illuminates micro-cracks in ordinary concrete
January 28, 2022Although concrete can be altered in order to help tiny cracks show up before they become catastrophic, scientists have now discovered that regular concrete does the job pretty well itself. It just needs a coat of ordinary paint, and a light source. -
Upcycled adhesive is one of the toughest materials ever reported
January 24, 2022By carefully tinkering with the chemical structure of a common household plastic, scientists have managed to upcycle it into a reusable adhesive with unique properties, billing it as one of the toughest materials known to science. -
Eco-friendly plastics made from sugars boast "unprecedented" properties
January 17, 2022Researchers have produced a new form of plastic with "unprecedented" mechanical properties that are maintained throughout standard recycling processes, and managed to do so using sugar-derived materials as the starting point.

Study suggests that most fishes communicate with sound
January 28, 2022We generally don't think of fish as being a vocal bunch – after all, anglers don't typically use "fish calls" to lure them in. According to a new study, however, approximately two-thirds of all fish species probably use sound to communicate. -
Scientists announce first known case of orcas killing an adult blue whale
January 27, 2022Along with eating fish and seals, killer whales (aka orcas) are also known to hunt some types of whales. For the first time ever, however, there has now been a documented case of them killing the largest animal in the world – an adult blue whale. -
Drug cocktail regrows frog legs in regenerative medicine breakthrough
January 26, 2022Animals like axolotls can regrow fully functional replacements for lost limbs. In a breakthrough new study, scientists have demonstrated how one dose of a drug cocktail can regrow lost limbs in frogs that don’t normally have regenerative abilities.

Giant A-68 iceberg dumped 152 billion tonnes of freshwater into the sea
January 20, 2022The environmental impacts of iceberg A-68 are still being assessed. A new study has calculated that the largest chunk, A-68A, released billions of tonnes of freshwater into the sea near a marine nature reserve, with untold effects on the ecosystem. -
Study finds chemical pollution is now beyond safe boundary for the planet
January 18, 2022Manufacturing of chemicals has grown so rapidly that governments are now unable to assess, let alone control the risks to Earth's ecosystems, taking us beyond a safe "planetary boundary" and endangering the planet's stability. -
Liquid metal catalyst quickly converts carbon dioxide into solid carbon
January 18, 2022A new method quickly converts carbon dioxide into solid carbon, which can be stored indefinitely or turned into useful materials. The technology works by bubbling CO2 up through a tube of liquid metal, and could be used at the source of emissions.

"Quantum tornadoes" mark crossover from classical to quantum physics
January 06, 2022The universe is governed by two sets of seemingly incompatible laws of physics – classical and quantum physics. MIT physicists have now observed the moment atoms switch from one to the other, as they form intriguing “quantum tornadoes.” -
CERN experiments investigate whether antimatter falls up or down
January 05, 2022Physicists at CERN have discovered that antimatter falls down. It sounds obvious, but scientists hadn’t yet been able to confirm that it responds to gravity in the same way as regular matter does. A new experiment provides the best answer so far. -
Is the universe's dark matter hiding in primordial black holes?
January 04, 2022A new model by a team of scientists led by Yale University suggests that the ever elusive dark matter that has so far escaped the detection of scientists may be trapped inside primordial black holes left over after the Big Bang.
