Record-Setting NASA Astronaut Peggy Whitson Retires

NASA astronaut Peggy Whitson, who holds the U.S. record for most cumulative time in space, is retiring from the agency, effective Friday.

New form of matter may lie just beyond the periodic table

Currently, the heaviest element on the periodic table is oganesson, which has an atomic mass of 294 and was officially named in 2016. Like every element on the periodic table, nearly all of oganesson's mass comes from protons and neutrons (types of baryons) that are themselves made of three quarks each. A crucial feature of all known baryonic matter is that its quarks are bound together so tightly by the strong force that they are inseparable.

A new experiment to understand dark matter

Is dark matter a source of a yet unknown force in addition to gravity? The mysterious dark matter is little understood and trying to understand its properties is an important challenge in modern physics and astrophysics. Researchers at the Max Planck Institute for Radio Astronomy in Bonn, Germany, have proposed a new experiment that makes use of super-dense stars to learn more about the interaction of dark matter with standard matter.

CERN starts major upgrade to reap more data at atom smasher

The world's largest particle smasher is kicking off a major upgrade to churn out 10 times more data and help unlock the secrets of physics.

The chances of detecting clumps in atomic nuclei are growing

What do atomic nuclei really look like? Are the protons and neutrons they contain distributed chaotically? Or do they perhaps bind into alpha clusters, that is, clumps made up of two protons and two neutrons? In the case of several light nuclei, experimental confirmation of the individualism or family nature of nucleons will now be simpler, thanks to predictions presented by Polish physicists from Cracow and Kielce.

Hawking's voice to be beamed into space during memorial

A message from late British astrophysics giant Stephen Hawking will be beamed towards the nearest black hole as his remains are laid to rest in London's Westminster Abbey on Friday.

Quantum transfer at the push of a button

In the new quantum information technologies, fragile quantum states have to be transferred between distant quantum bits. Researchers have now realized such a quantum transmission between two solid-state qubits at the push of a button.

Realization of high-performance magnetic sensors due to magnetic vortex structures

Magnetic sensors play a key role in a variety of applications, such as speed and position sensing in the automotive industry or in biomedical applications. Within the framework of the Christian Doppler Laboratory "Advanced Magnetic Sensing and Materials" headed by Dieter Süss novel magnetic sensors have been realized that surpass conventional technologies in performance and accuracy in a cooperation between the University of Vienna, the Danube University Krems and Infineon AG. The researchers present the new development in the latest issue of the journal Nature Electronics.

Higgs boson, top quarks linked in milestone collider discovery

An observation made by an experiment at the Large Hadron Collider involving Florida Institute of Technology physicists Francisco Yumiceva, Marcus Hohlmann and Marc Baarmand has for the first time connected the two heaviest elementary particles of the Standard Model.

Research shows short gamma-ray bursts do follow binary neutron star mergers

Researchers at Oregon State University have confirmed that last fall's union of two neutron stars did in fact cause a short gamma-ray burst.
