Understanding the ionisation of proton-impacted helium

Advanced mathematical analysis of the ionization of a helium atom by an impacting proton has revealed where discrepancies arise between experiments and existing theoretical calculations of the process

SuperBIT: A low-cost, balloon-borne telescope to rival Hubble

Durham, Toronto and Princeton Universities have teamed up with NASA and the Canadian Space Agency to build a new kind of astronomical telescope. SuperBIT flies above 99.5% of the Earth's atmosphere, carried by a helium balloon ...

Electrons in quantum liquid gain energy from laser pulses

The absorption of energy from laser light by free electrons in a liquid has been demonstrated for the first time. Until now, this process was observed only in the gas phase. The findings, led by Graz University of Technology, ...

A deep reservoir of primordial helium in the Earth

Noble gases, including helium, neon, and argon, are characterized by high chemical inertness which causes low reactivity with other materials and high volatility. Among them, 3He, 20Ne, and 36Ar are particular isotopes which ...

Bats found to have innate sense of speed of sound

A pair of researchers with Tel Aviv University's School of Zoology has found that bats have an innate sense of the speed of sound. In their paper published in Proceedings of the National Academy of Sciences, Eran Amichai ...

Researchers find bubbles speed up energy transfer

Energy flows through a system of atoms or molecules by a series of processes such as transfers, emissions, or decay. You can visualize some of these details like passing a ball (the energy) to someone else (another particle), ...

An improved safety standard for bionic devices

Applied physicists at the University of Sydney have proposed new standards to measure moisture leaks into bionic devices such as pacemakers, cochlear hearing implants and retinal replacements.
