The Science of Cellulitis

This week, Professor Luke O’Neill turns his microscope to a condition he knows all too well — cellulitis. It’s one of the most common bacterial infections there is, affecting about one in every 500 people each year. The skin turns red, swollen, and sore, and you might even feel flu-ish as your immune system fights back. Left untreated, it can spiral into sepsis, making early diagnosis vital. Listener Joanie suggested this week’s theme, and you can do the same by emailing Luke at laoneill@tcd.ie. As Luke explains, cellulitis happens when bacteria slip through tiny breaks in the skin — a scratch, a cut, even an insect bite — and start multiplying. He suspects that’s how he picked it up himself earlier this year. Rates of cellulitis are on the rise, with hospitals seeing more admissions, especially in settings where people live in close quarters: nursing homes, homeless shelters, and college dorms. Obesity and antibiotic resistance may also be fuelling the increase. Treatment is straightforward (antibiotics usually clear it up) but prevention is even better. Keeping skin clean and moisturised, and treating any breaks promptly, can stop it taking hold. And it’s not just humans. Cats, dogs and even horses can suffer from cellulitis, with vets watching closely for swelling and lameness. In fact, that old-fashioned poultice once used to “draw out” infection still has its place — at least in the stable. From microbes to moisturiser, Luke explores how our skin keeps the world out. And what happens when it can’t.

Soon enough, gardaí were on the scene and beginning their investigation, and a Ford car became a focus point. Una's body hadn't been found but the investigating officers were convinced within weeks they'd solved the case. Or had they?

Episode 05: An Innocent Man

Having been convicted of Una Lynskey's murder, Martin Conmey and Dick Donnelly began their sentences in Mountjoy prison in 1972. For Martin, his release almost three years later was supposed to mean a return to normality and a fresh start, but he found it almost unbearably hard to live with everything that had happened. However more than a decade later, one seminal moment in the history of The Troubles would ignite a determination in Martin to challenge the might of the State once more. It would take a change in the law, the unyielding love of his family, and yet more battles in the courtroom, but Martin set out to try get his conviction quashed.

Episode 04: A Hostile Witness

Just a few months after the horrific events of December 1971, Martin Conmey and Dick Donnelly were charged Una Lynskey's murder. Martin had made a false confession to gardaí at Trim Garda Station, however Dick refused to sign anything despite claiming he came under similar pressure. They each hoped that the truth would emerge before the judge and jury at the Central Criminal Court in the height of the summer of 1972. In this episode, we'll bring you into the courtroom for those 13 days of evidence - could they put their faith in Lady Justice?

Episode 03: Another Abduction

Having made false confessions to gardaí, Martin Conmey and Marty Kerrigan hoped the truth about what happened to Una Lynskey would emerge somehow, and this would lift the finger of suspicion. Her body was found before the end of 1971 and the investigation into her disappearance was upgraded to murder, but unfortunately it only added fuel to the fire of rumours already doing the rounds of Porterstown Lane. And very quickly afterwards, an act of misplaced vengeance would soon bring more tragedy to the lane.

SEASON 3, EPISODE 1

Episode 01: Missing

Una Lynskey was 19 years old in October 1971, and she had a job with the Land Commission in Dublin City. On the evening of Tuesday 12th October, she stepped off a bus on the Fairyhouse Road near Ratoath, Co Meath when she hurried up Porterstown Lane towards her family's farm, a walk that would take no more than 15 minutes. She never made it home. A search began within the hour, but there was no sign of her. However, soon there were repeated descriptions of an unusual car on the lane that afternoon, and a number of locals in the area remembered hearing screams not long after Una got off the bus. Who would have taken her? And why?
