Study: International scientists believe lack of women in physics tied to personal preference, but viewpoint ignores gender norms

Matter and energy from Science Daily Feed - Thu, 12/07/2023 - 1:14pm
Fewer women pursue careers in physics than biology, and scientists from around the world believe these differences come down to personal preferences, according to a new study of international scientists. The study's researchers warn that merely chalking this imbalance up to individual choice may diminish the push for gender equality in the sciences.

Magnetization by laser pulse

Matter and energy from Science Daily Feed - Thu, 12/07/2023 - 1:14pm
To magnetize an iron nail, one simply has to stroke its surface several times with a bar magnet. Yet, there is a much more unusual method: A team has discovered some time ago that a certain iron alloy can be magnetized with ultrashort laser pulses.

Polaritons open up a new lane on the semiconductor highway

Computers and Math from Science Daily Feed - Thu, 12/07/2023 - 1:13pm
On the highway of heat transfer, thermal energy is moved by way of quantum particles called phonons. But at the nanoscale of today's most cutting-edge semiconductors, those phonons don't remove enough heat. That's why researchers are focused on opening a new nanoscale lane on the heat transfer highway by using hybrid quasiparticles called 'polaritons.'

Ancient stars made extraordinarily heavy elements

Matter and energy from Science Daily Feed - Thu, 12/07/2023 - 1:04pm
How heavy can an element be? An international team of researchers has found that ancient stars were capable of producing elements with atomic masses greater than 260, heavier than any element on the periodic table found naturally on Earth. The finding deepens our understanding of element formation in stars.

Soundwaves harden 3D-printed treatments in deep tissues

Matter and energy from Science Daily Feed - Thu, 12/07/2023 - 1:04pm
Engineers have developed a bio-compatible ink that solidifies into different 3D shapes and structures by absorbing ultrasound waves. Because the material responds to sound waves rather than light, the ink can be used in deep tissues for biomedical purposes ranging from bone healing to heart valve repair.

Catalyst for electronically controlled C--H functionalization

Matter and energy from Science Daily Feed - Thu, 12/07/2023 - 1:04pm
Scientists chipping away at one of the great challenges of metal-catalyzed C--H functionalization with a new method that uses a cobalt catalyst to differentiate between bonds in fluoroarenes, functionalizing them based on their intrinsic electronic properties. And their method is fast -- comparable in speed to those that rely on iridium.

How a failure to understand race leads to flawed health tech

Computers and Math from Science Daily Feed - Thu, 12/07/2023 - 12:13pm
A new study focused on wearable health monitors underscores an entrenched problem in the development of new health technologies -- namely, that a failure to understand race means the way these devices are developed and tested can exacerbate existing racial health inequities.
