Researchers from Osaka University and IMRA AMERICA demonstrated a 300 GHz-band wireless link that was able to transmit data over a single channel at a rate of 240 gigabits per second. The wireless communication system employs signal generators based on lasers that have ultra-low phase noise in the sub-terahertz band. This rate is the highest so far reported at these frequencies and is a substantial step forward in 300 GHz-band communications for 6G networks.

A team of researchers from Osaka Metropolitan University assessed the feasibility of conducting cardiopulmonary exercise testing with the upper limbs as an alternative to the conventional method that uses the lower limbs. The researchers investigated the relationship between heart rate and oxygen uptake during exercise stress tests using a cycle ergometer and an arm crank ergometer, and estimated maximal oxygen uptake. The study participants were 17 male collegiate athletes from rowing and cycling clubs. The results showed that the estimated maximal oxygen uptake for both rowing and cycling groups was lower on the arm crank ergometer than on the cycle ergometer. Additionally, this study showed that exercise testing using an upper extremity ergometer underestimates cardiopulmonary function, regardless of upper limb training status.

A recent paper published in the journal Astronomy & Astrophysics presents new images from the 2018 data that reveal a familiar ring the same size as observed in 2017. This bright ring surrounds a deep central depression, “the shadow of the black hole,” as predicted by general relativity. Excitingly, the peak brightness of the ring has shifted by about 30º counter clockwise compared to its position in 2017, which is consistent with our theoretical understanding of the variability of the turbulent material around black holes.
