Scientists warn popular vitamin D supplement may have a “previously unknown” downside

A surprising study suggests vitamin D2 supplements may reduce the body’s levels of vitamin D3 — the more effective form of vitamin D. Researchers found D3 not only boosts vitamin D status more efficiently, but may also play a unique role in helping the immune system fight off viruses and bacteria. The discovery is prompting scientists to rethink whether D3 should become the preferred choice for supplementation.

Robinson strikes twice but rain halts England’s charge against New Zealand

1st Test, D3: England, 140 & 226; New Zealand, 113 & 55-5Ravindra and Mitchell fall to Robinson amid rain at Lord’sJust 58 legal deliveries – plus one no ball – were bowled as rain dominated the third day here. It was an unsatisfyingly brief glimpse of action that nevertheless allowed England to upgrade their chances of victory in the first Test after their post-Ashes reset from probable to overwhelmingly likely. New Zealand scored 19 runs and lost two wickets, leaving them on 55 for...

Two-component exciton condensates in an electron–hole bilayer

Abstract Macroscopic quantum coherence emerges when bosons condense into a Bose–Einstein condensate (BEC)1,2,3,4,5. Excitons are a long-sought solid-state route to high-temperature BECs with strong interactions, electrical tunability and potentially multicomponent spinor order, but conclusive evidence for equilibrium condensation has remained elusive. Here we report evidence for two-component exciton BECs in MoSe2/hBN/WSe2 electron–hole bilayers6,7,8,9 by probing the spin–valley...

World Cup 2026: Can sub-Saharan Africa outdo noisy neighbours from north? After Morocco became the first Africans to reach a World Cup semifinal in 2022, can a sub-Sahara side step up in 2026? Africa’s performance at World Cups peaked at Qatar 2022 when Morocco became the first side from the continent to reach the semifinal stage.

Influence of DFT Functionals on Low-Energy Electron Scattering Cross Sections of Nitric Oxide

Announce Type: new Abstract: Nitric oxide (NO) is important in biological, atmospheric, plasma, industrial, and astrophysical environments, where reliable electron-collision data support modelling charged-particle interactions with matter. Its well-known experimental properties make it suitable for assessing how the target electronic-structure description affects low-energy electron scattering calculations. In this work, NO properties were evaluated using B3LYP, M06-2X, PBE0, and...

Light-induced quantum friction of carbon nanotubes in water

Abstract Friction slows down moving objects at both macroscopic and microscopic scales1. At the electronic level, quantum friction describes direct transfer of momentum between a liquid and the electrons of a solid2. Owing to its microscopic nature, this phenomenon remains experimentally challenging to capture3.

Ahoy, DECmate II the little PDP-8 that could

Now, that's a lot of word processing. But under the hood it's still at least PDP-8 adjacent, even considering its oddities and incompatibilities, and you can make it do many of the things a full-size Eight can. We'll take this basic unit, convert the floppy drives to solid state, tap the video output, and put it through its paces.

Depolarization and Polarization-Transfer Rates for Solar He I Lines due to Collisions with Neutral Hydrogen

Announce Type: cross Abstract: Context. Neutral helium (He I) produces several spectral lines that are widely used for solar diagnostics. The role of collisions between He I atoms and neutral hydrogen (H I) in the modeling of solar He I lines remains insufficiently quantified.
