Health Matters … Threadworm
In the second of a series of articles on health, pharmacist and writer Asha Fowells looks at threadworms. This may make you go ‘euuuuuw’, but it is an important thing to know about, because while threadworms are icky, they are reasonably easy to treat.
The term “parasitic infection” may make you think of intrepid explorers in rainforests and jungles, but there is one parasite that lurks much closer to home: threadworm.
The Clifton suspension bridge: designed by a woman, built by Brunel
One of the best known landmarks in Bristol, UK, the Clifton suspension bridge first opened in 1864. It was built by the famous British engineer Isambard Kingdom Brunel, but it has recently become public knowledge that it was designed by a woman. Our science editor Sam Gouldson explains who she was and why her work isn’t more widely known.
Who really designed the bridge?
The Clifton suspension bridge was designed by a woman called Sarah Guppy. She was born Sarah Beach in 1770, but when she married her husband Samuel Guppy she took his name. She was one of the great British inventors of her time and the bridge isn’t the only thing she came up with.
What else did she design?
The invention that earned Sarah the most money was her device to prevent barnacles forming on the hulls of ships. Without barnacles the ships would be able to cut better through water and travel more quickly, and the Royal Navy paid her £40,000 for it. That may not sound like much for such a valuable design, but today it would be more than £2.3 million. Her other inventions included a kettle that not only boiled water for tea but could cook an egg and keep toast warm, a candle holder that could keep candles alight for longer and a way of treating boats so that they were more watertight. She also came up with the idea of planting willow and poplar trees on the embankments of new railways, to hold the earth together and prevent landslides.
Why isn’t she more famous?
Sarah lived during the Georgian and Victorian eras. In those times married women weren’t allowed to own property in their own name, and intellectual property such as Sarah’s inventions were no different. Her husband had to file the patents on her behalf, as the property of the Guppy family. The patent for her method of piling bridge foundations in order to create a new kind of bridge was filed in 1811, but she refused to charge others to use the idea because she felt it was for the benefit of the public. Thomas Telford, a civil engineer, used her design to build the Menai bridge in 1826, and when the competition to design the Clifton bridge was announced Sarah gave her work to Brunel. When she wrote to him to suggest the use of willow and poplar trees to reinforce railway embankments, she explained that she didn’t want the credit for her idea because she felt that women “must not be boastful”.
It just IS Cricket – Women’s Cricket Around the World
Cricket is inspiring young women in the most unexpected places, by providing hope and possibility to girls worldwide. The men’s game may make many of the headlines, but there are growing opportunities for women to play, even in the most traditional cultures.

No, Tina didn’t turn into the cute little furry rodent (although that would be awesome) but became a ‘subject of scientific research’. Find out what that means, and what she had to do!
The Best Urban Beaches
Who else is looking forward to the summer? Whether you call your summer break a ‘vacation’ or a ‘holiday’, there is a good chance that some of you are heading for the beach.
Did you know that around the world there are hundreds of artificial beaches. Some are near the coast, but others are miles away from the seaside – perfect for those who don’t or can’t travel far.
City beaches are sometimes called ‘urban beaches’ like the one above in Cologne, Germany. This can involve the delivery of hundreds of tonnes of sand, to a place where there is no sand.
Islands Brygge, Copenhagen, Denmark
There is no sand here, but it is an oasis of fun in the middle of the city. For many years, this area was run down and neglected, but after a regeneration project, new life is blossoming. Who wants to jump off this diving board?
Festival of Love Beach, South Bank, London UK
This beach is all about relaxing and digging your feet into the sand. No pool (and the chilly Thames is certainly no alternative!) but great views over London, and the South Bank centre often has great activities for kids on offer. Check out their website for details.
Paris Plage, France
The capital city of France can get really hot and muggy in the summer months, so what better way than to cool off at an urban beach? Check out the huge showers in the picture!
Bundek Lake, Zagreb, Croatia
In the south of the city of Zagreb, this park was brought back to life after many years of neglect. It is a popular spot for locals and tourists alike, hoping to cool off in the hot Croatian summers.
Baby Plage, Geneva, Switzerland
Baby Plage, Geneva
This might be the MOST fun urban beach for kids in the world. The huge trees are festooned with old tyres and bicycle tubes, knotted together to create ladders and swings.
San Alfonso del Mar, Chile
Ok, this is a bit of a cheat, cause it isn’t an urban beach, but it is the biggest swimming pool in the world, so we had to include it! It is 8 hectares, and holds 250 million liters of water. That is equivalent of 6,000 familiar 8m long pools! It is part of a privately owned complex in South America.
BONUS BEACHES
Now, don’t tell your parents that we showed you this, and don’t try it out at home, but how awesome does this look? We can’t help thinking that this would be VERY messy, but it looks so relaxing and fun!

This was built in Japan in 1993 – an artificial beach with a retractable roof. It was not commercially successful and closed over 10 years ago. Which is a real shame, because it looks really amazing.
