It’s a world-first: A paralysed man, Michel Roccati, with a severed spinal cord has taken his first steps in years

In 2017 Roccati became paralysed after a serious motorcycle accident which caused him to lose all feeling in his legs.

It wasn’t until Swiss researchers, neuroscientist Prof Grégoire Courtine and neurosurgeon Prof Jocelyne Bloch, developed an electric implant that was surgically attached to the patient’s spine which allowed him to walk again.

It’s the first time someone with a complete cut to their spinal cord has regained their ability to walk.

“This is a monumentally huge step forward,”
says Dr Ronaldo Ichiyama at the University of Leeds, UK.

Alongside Roccati, the electrical implant has helped two other patients according to the research team, which has sparked hope for paralysed people to gain back their independence.

Even though this is a major advance in technology, Dr Ichiyama says this needs to be seen in more people before everyone gets “too excited”.

The gift of technology

Michel Roccati called the technology a “gift” and now utilises the implanted device for up to two hours a day to go on walks by himself.

The range of simulation programs also allows him to also stand, cycle and swim.

But researchers are emphasising that it isn’t a cure for a spinal injury and is still too complex for everyday life. It is expected that the technology will continue to be developed and strengthened.

Investors monitor Big Tech’s AI investments, with Meta thriving while Microsoft and Tesla face uncertainty over growth and returns.

Investors are reacting sharply to Big Tech earnings this week, sending a clear signal that massive spending must translate into real growth. Markets are becoming less forgiving as companies pour billions into artificial intelligence, data centres and future tech while returns remain uncertain.

Meta has delivered a standout performance, posting a 24 percent jump in revenue for the December quarter, fuelled by AI-powered advertising. The company is doubling down on its strategy, with aggressive investment in AI and infrastructure expected to drive a further 33 percent growth this quarter.

Microsoft and Tesla tell a more cautious story. Microsoft reported only modest growth in its Azure cloud business, raising questions about its exposure to OpenAI, while Tesla plans to double spending on AI and autonomous driving. Analysts warn of a widening gap between bold AI ambitions and what investors expect in returns.

Memory chip supply tight, prices high; Lenovo warns rising costs impact budget devices amid strong PC demand from Windows 11.

Memory chips critical to consumer electronics and AI data centres remain in tight supply, keeping prices elevated despite production expansion by major players including Samsung and Micron.

Lenovo warns higher memory costs will hit budget devices first, even as PC demand stays strong from Windows 11 upgrades.
