High-resolution imaging of Cygnus X-1 shows the star’s strong stellar wind bends the black hole’s jets, enabling the first direct estimate of jet power—about 10,000 times the Sun’s luminosity. This reveals how a star’s wind shapes jet behavior, helping balance the black hole’s energy budget and refine galaxy-scale simulations.
A study published in PNAS found that increased physical activity leads to higher daily calorie burn without the body compensating by reducing energy use elsewhere, supporting an additive model of energy expenditure.
A study published in PNAS shows that increased physical activity leads to higher daily calorie burn without the body compensating by reducing energy use elsewhere, supporting the idea that exercise adds to overall energy expenditure rather than redistributing it. The research involved measuring energy use in participants with varying activity levels and found that more active individuals burn more calories overall, with less time spent inactive, although further research is needed to understand potential energy compensation under different conditions.
