‘4 different kinds of dinosaur’: A new discovery in southeastern Utah - CTV News

Most conventional methods of ultrafast photography use evenly spaced intervals in which images are taken, but new developments have shown how much can be left out of the story, especially when multiple timescales are involved.

Uranus and Neptune are often described as near-twins, but a new study suggests their chemistry, and possibly their histories, may differ more than expected. The materials making up Neptune and Uranus likely came from different regions in the protoplanetary disk around the young Sun. Image credit: SwRI.

Every cell in the human body faces a chronic challenge: protecting its DNA. Whenever cells divide, their genetic material must be copied accurately. But DNA is continuously under attack, and when damage goes unrepaired, it can threaten genome stability and contribute to the progression of disease.

A new theory on the birth of the cosmos has been unveiled, suggesting the early universe was shaped by an ancient particle that has been overlooked for decades. The research, published in the journal Physical Review Letters, tackles one of the greatest conundrums in modern physics — how matter triumphed over antimatter in the aftermath of the “Big Bang”. According to current theories, both should have annihilated each other after a colossal explosion — leaving nothing but an empty universe of pure energy. But physicists at the University of Southampton and the Indian Institute of Technology Kanpur say they found a clue in a neutrino, one of the lightest particles in the universe. The research team discovered that an often-ignored relative of the particles — known as a “decoupled” heavy neutrino — could have helped matter dominate over its counterpart.

Pulsars are rapidly rotating neutron stars, the extremely dense cores left behind when massive stars explode. Astrophysicists have recently observed a pulsar rotating over 300 times per second that appeared to be slowing down unusually quickly.
