Cryogenic preservation: from single cells to whole organs – Science Weekly podcast

Subscribe & Review on iTunes, Soundcloud, Audioboom, Mixcloud & Acast, and join the discussion on Facebook and Twitter


Last year, around 3,500 organs were transplanted into patients in the UK alone. That said, a large number of organs were also discarded because the moment a donor dies, doctors have only eight or so hours to find a patient on the organ register who is a match and can be almost immediately ready for surgery. One recent estimate suggested that as many as 60% of the hearts and lungs donated for transplantation are discarded each year. But a new technology could be about to change this: whole-organ cryopreservation.


This week, Hannah Devlin looks at the past, present, and future of these technologies with University College London’s Professor Barry Fuller. We also hear from Newcastle University bioethicist Dr Simon Woods about some of the ethical issues that arise with any biotechnology, including cryopreservation.

The male contraceptive pill: how close are we? – Science Weekly podcast

Subscribe & Review on iTunes, Soundcloud, Audioboom, Mixcloud & Acast


On June 23rd 1960, the US Food and Drug Administration approved the world’s first combined oral contraceptive pill – or COCP – known as Enovid. And whilst there have been many developments in COCPs for women in the six decades that have followed, effective counterparts for men have yet to appear on to the market. Why has it taken so long? How close are we to a male contraceptive pill?


This week, Hannah Devlin hears from the University of Edinburgh’s Professor Richard Anderson, who was part of a recent World Health Organisation funded trial into a male contraceptive jab. We also talk to Dr Diana Blythe of the NICHD’s Male Contraceptive Development Program, about the progress being made Stateside using gels instead of jabs. And finally, we hear about non-hormonal alternatives in development from Aaron Hamlin, executive director of the Male Contraceptive Initiative.

On 4th August 1997, Jeanne Louise Calment died in a French nursing home. Born 122 years and 164 days earlier, Jeanne currently holds the record for the greatest fully authenticated age to which any human has ever lived. And with the ever-growing average life expectancy for humans showing no sign of slowing down, how close are we to cracking the code of longevity?


Helping Nicola Davis delve into the age-old problem of ageing this week, prominent biomedical gerontologist Dr Aubrey De Grey reveals his unique, seven-step approach to the problem of ageing. We ask Harvard University’s Dr Justin Werfel why programmed death might be a good thing. And we hear how the University of Kent’s Dr Jenny Tullet is using roundworms to reveal clues about the genetics of ageing.

The variety of cases of scarlet fever has reached a record weekly higher, overall health officials have warned.


Public Wellness England (PHE) stated there was a “continued substantial increase” in the number of situations in England.


In the last week of March officials had been notified of 883 new situations – the highest weekly total given that 1982 when weekly data started, a spokeswoman said.


Since September 2013 PHE has mentioned 5,012 new instances when they would usually only count on to see all around one,400.


“We are continuing to see increases in scarlet fever notifications across England and are operating closely with healthcare professionals to try out and understand the motives behind these increases and do our very best to minimize the influence of this infection,” mentioned PHE’s head of streptococcal infection surveillance, Dr Theresa Lamagni.


“PHE urges men and women with symptoms of scarlet fever, which consist of a sore throat, headache and fever accompanied by a characteristic rash, to seek the advice of their GP. Scarlet fever should be handled with antibiotics to reduce risk of problems.


“When children or adults are diagnosed with scarlet fever we strongly advise them to remain at home till at least 24 hrs following the start of antibiotic remedy to steer clear of passing on the infection.”


Scarlet fever is a very contagious bacterial sickness that brings about a distinctive pink-red rash which feels like sandpaper to touch.


It can be itchy and start in 1 region, but soon spreads to a lot of components of the entire body, such as the ears, neck and chest.


Other signs consist of a substantial temperature, vomiting, a flushed encounter and a red, swollen tongue.


Scarlet fever usually follows a sore throat or skin infection and is most typical among the ages of two and eight.


It is caught by breathing in bacteria in airborne droplets from an contaminated person’s coughs and sneezes, or by means of touching their skin.


Sharing contaminated towels, baths, outfits, bedding, cups and utensils can also pass on the infection.


It is handled by antibiotics which must be taken for 10 days, even even though most people recover following four to five


There are typically seasonal rises in scarlet fever between December and April each and every yr. Each and every number of many years there is also a notable boost in the number of circumstances and the most current bout of infections is likely to be part of that cycle, specialists have explained.

Science Weekly podcast: the wonder of human skin

This week’s podcast is only skin deep as we dedicate the demonstrate to an extended interview with Professor Des Tobin.


Des informed Dr Natalie Starkey about the newest scientific study into anti-ageing skin remedies, how a pill might replace skin lotions, and why skin well being is crucial. He and Natalie have been chatting at final year’s British Science Festival in Newcastle, where Prof Tobin gave a presentation.
