Gigantic dinosaur may be the largest land animal ever
Fossils found in Argentina may belong to the largest creature ever to walk the Earth. Plus: the superconductor breakthrough that could spark an energy revolution.

A gigantic titanosaur being excavated in Argentina may be the largest animal that we have ever found. The titanosaurs include Patagotitan – sometimes claimed to be the largest land animal ever to exist, estimated at 50 to 55 tonnes in weight. So far, the team has unearthed 24 vertebrae, as well as some pelvis bones. According to their research paper, the team isn’t sure what species the bones might belong to, but there are “clear differences” between the bones and those of previously unearthed dinosaurs in the region. This suggests the fossils could be evidence of an unknown titanosaur, and though its full size has not yet been determined, it probably exceeds Patagotitan, the researchers believe. Read more
Entangled photons have been sent between two drones hovering a kilometre apart, demonstrating technology that could form the building blocks of a quantum internet. When a pair of photons are quantum entangled, you can instantly deduce the state of one by measuring the other, regardless of the distance separating them. This phenomenon is the basis of quantum encryption – using entangled particles to ensure communications are secret. Entangled photons have been transported more than 1000 kilometres in tests between a satellite and ground stations before, but now researchers in China have shown that links can be made over shorter distances with relatively inexpensive hardware. It is also the first time that photon entanglement has been transmitted from one moving device to another. Read more

Can you dig it?: After nearly two years of attempting to dig into Mars’s surface using a probe nicknamed the mole on the InSight lander, NASA engineers have finally given up.
Northern white rhino: Fertilised eggs are set to be implanted in the last two remaining rhinos of the subspecies this year in the hope of producing offspring.
A Perfect Planet: Cryogenic frogs and blood-sucking finches are among the many remarkable animals that star in David Attenborough’s latest series examining what makes Earth so perfect for life.
Reasons for hope: Despite the ongoing climate and biodiversity crises, there is a whiff of green optimism in the air, says Graham Lawton.

Superconductors are materials that conduct electricity without losing any of it as heat, and a practical one would revolutionise how we transport and store energy in an era of climate change. But while we’ve known about superconductors for over a century, difficulties in working with the materials, above all the extremely low temperatures they need to function, have limited them to niche applications, for instance in hospital MRI scanners. Now a slew of breakthroughs looks to be changing that – not least the discovery of the first room-temperature superconductor. Read more
