Fossils indicate a communal nesting ground and adults who foraged and took care of the young as a herd, scientists say.
To borrow a line from the movie “Jurassic Park:” Dinosaurs do move in herds. And a new study shows that the prehistoric creatures lived in herds much earlier than previously thought.

A new control system, demonstrated using MIT’s robotic mini cheetah, enables four-legged robots to jump across uneven terrain in real-time. A loping cheetah dashes across a rolling field, bounding over sudden gaps in the rugged terrain. The movement may look effortless, but getting a robot to move this way is an altogether different prospect.
In recent years, four-legged robots inspired by the movement of cheetahs and other animals have made great leaps forward, yet they still lag behind their mammalian counterparts when it comes to traveling across a landscape with rapid elevation changes.
Such planetary smashups are likely common in young solar systems, but they haven’t been directly observed.
Young planetary systems generally experience extreme growing pains, as infant bodies collide and fuse to form progressively larger planets. In our own solar system, the Earth and moon are thought to be products of this type of giant impact. Astronomers surmise that such smashups should be commonplace in early systems, but they have been difficult to observe around other stars.
Now astronomers at MIT, the National University of Ireland Galway, Cambridge University, and elsewhere have discovered evidence of a giant impact that occurred in a nearby star system, just 95 light years from Earth. The star, named HD 172,555 is about 23 million years old, and scientists have suspected that its dust bears traces of a recent collision.
The Large Hadron Collider (LHC) sparked worldwide excitement in March as particle physicists reported tantalizing evidence for new physics – potentially a new force of nature.
Now, our new result, yet to be peer reviewed, from CERN’s gargantuan particle collider seems to be adding further support to the idea.
Our current best theory of particles and forces is known as the standard model, which describes everything we know about the physical stuff that makes up the world around us with unerring accuracy.
Russia has registered the world’s first COVID-19 vaccine for animals, the country’s agricultural regulator said on Wednesday.
Clinical trials of the vaccine — called Carnivac-Cov — started last October and involved dogs, cats, Arctic foxes, minks, foxes and other animals, said Konstantin Savenkov, deputy head of Rosselkhoznadzor, according to a Reuters report.
Ingham County cat tested positive for virus that causes COVID-19. Its owners were confirmed to have COVID-19 about a week before the cat became ill.
The zoo said it has been vaccinating big cats, great apes, red pandas, goats, giraffes, river otters, skunks, bearcats and some domestic dogs and cats.
FDA amended the emergency use authorization (EUA) for the Pfizer-BioNTech COVID-19 Vaccine to allow for the use of a single booster dose, to be administered at least six months after completion of the primary series with the Pfizer-BioNTech COVID-19 Vaccine in certain populations.
It’s Time to welcome our Space Brothers.
Is there intelligent life elsewhere in the universe? It’s a question that has been debated for centuries, if not millenia. But it is only recently that we’ve had an actual chance of finding out, with initiatives such as Seti (Search for Extraterrestrial Intelligence) using radio telescopes to actively listen for radio messages from alien civilisations.
What should we expect to detect if these searches succeed? My suspicion is that it is very unlikely to be little green men—something I speculated about at a talk at a Breakthrough Listen (a Seti project) conference.
We have achieved strong, fast, power-dense, high-efficiency, biomimetic, soft, safe, clean, organic and affordable robotic technology. Dumbbell weights 7 kg (15,6 lbs) 0 forearm with hand only 1 kg (2,2 lbs).
This artificial muscles robotic arm is operated by water and consumes 200W at peak. We invent and produce portable power supply and our own electro-hydraulic mini valves to have complete controllability of speed contraction and compress the whole powering system (for a full body) inside humanlike robot torso.
