History suggests tech shares poised for new highs in 2021

Column chart of Per cent showing Global tech stocks made big gains following mid-cycle corrections

The Nasdaq 100 index of the world’s largest technology companies suffered a tough run in September, shedding 5.7 per cent in its biggest pullback since the coronavirus shock in March. But if the trading patterns of the past five years hold, it may not be long before the sector rebounds.

The latest decline came as a frenzied tech rally ran out of momentum, continuing a highly volatile year. Even after the drop in September, and a 7.7 per cent decline in March, the index is still up about 30 per cent in 2020.

Analysis from UBS shows that between 2015 and 2019, mid-cycle corrections in global tech stocks lasted an average of a month from peak to trough, and caused the sector to lose 11 per cent. The scale of the rebounds over the following six months was, on average, 20 per cent.

This year has been supersized. In 38

After lengthy delays, ULA’s most powerful rocket poised to launch classified spy satellite

After many weeks of delays due to faulty equipment and bad weather, the United Launch Alliance is set to launch its most powerful rocket from Cape Canaveral, Florida, lofting a classified spy satellite for the National Reconnaissance Office. The mission is finally ready to fly a full month after the rocket’s first launch attempt, which was aborted just three seconds before liftoff.

The rocket going up on ULA’s mission is the Delta IV Heavy, a giant vehicle that consists of three rocket cores strapped together to provide extra thrust. It’s one of the most powerful rockets in the world, though it falls short of the power packed into SpaceX’s Falcon Heavy. ULA doesn’t fly the Delta IV Heavy very often, as it’s an expensive vehicle to make, but the company uses the rocket for large, heavy satellites headed to super-high orbits.

The rocket’s payload is NROL-44, and like all NRO

New microendoscope poised to advance our understanding of the brain — ScienceDaily

Researchers have demonstrated a new endoscope that uniquely combines photoacoustic and fluorescent imaging in a device about the thickness of a human hair. The device could one day provide new insights into the brain by enabling blood dynamics to be measured at the same time as neuronal activity.

“Combining these imaging modalities could improve our understanding of the brain’s structure and behavior in specific conditions such as after treatment with a targeted drug,” said research team leader Emmanuel Bossy from the CNRS/ Université Grenobe Alpes Laboratoire Interdisciplinaire de Physique. “The endoscope’s small size helps minimize damage to tissue when inserting it into the brains of small animals for imaging.”

In The Optical Society (OSA) journal Biomedical Optics Express, Bossy’s research team, in collaboration with Paul C. Beard’s team from University College London, describe their new multi-modality endoscope and show that it can acquire photoacoustic and fluorescent images of red
