Is there an independent verification of the claims made by University of Buckingham researchers?

Professor Wainwright said the structure is made from the metals titanium and vanadium with a “gooey” biological liquid oozing from its centre.
He said there are several theories as to where it came from, the first being it is a complete microorganism programmed to propagate alien life on Earth.
“It is a ball about the width of a human hair, which has filamentous life on the outside and a gooey biological material oozing from its centre,” he said.
“We were stunned when X-ray analysis showed that the sphere is made up mainly of titanium, with a trace of vanadium.
“One theory is it was sent to Earth by some unknown civilisation in order to continue seeding the planet with life.

Professor Wainwright and his team found the object in dust and particulate matter collected from the stratosphere.
He sent balloons 27km into the sky to collect debris from space and isolated several particles he claims are proof of life in space.
