FlexSea’s biodegradable plastics attract £3m investment

01 FlexSea, a startup with its roots at Imperial College London, has announced the completion

02 of a seed round worth £3 million in equity and grants. The investment will help the company

03 commercialize a range of sustainable packaging solutions it has developed, based on plastics

04 derived from seaweed. The aim is to address the catastrophic impact of conventional plastics

05 on the environment, in particular the single-use plastic products that persist in the ocean for

06 many hundreds of years after they are discarded. In contrast, the biodegradable plastics

07 devised by FlexSea will break down in the sea or the soil within a matter of weeks.

08 Carlo Fedeli, the co-founder and Chief Executive of FlexSea, first started to think about

09 biodegradable plastics during the COVID pandemic. “I noticed the amount of plastic packaging

10 that was piling up at home, because of the online groceries and other deliveries we relied on

11 at the time, and I just had enough,” he says. He started looking into the biodegradable plastics

12 that were already available, and found that they often had shortcomings. Some didn’t actually

13 break down very rapidly under day-to-day environmental conditions, while others involved

14 unsustainable production methods. For example, plastics derived from seaweed are often made

15 from brown seaweed, which is usually harvested from nature, rather than the commonly

16 cultivated red seaweed. He set out to develop a thin-film plastic from red seaweed. “By the

17 end of lockdown I had the first prototype, a transparent flexi-film, and that is still the backbone

18 technology of our solvent-cast thin films,” he says.

19 FlexSea was set up in 2021 with co-founder Thibaut Monfort-Micheo. Their first home was

20 at Scale Space, on the White City Campus, and they received support from across Imperial's

21 enterprising ecosystem. In 2021 they joined the Centre for Climate Change Innovation’s

22 Greenhouse Accelerator, and in 2022 they took part in Imperial’s Venture Catalyst Challenge,

23 winning the energy and environment track. "FlexSea has the potential to change the pattern

24 of human consumption of plastic and therefore change the sustainability path of our planet,”

25 says Stephan Morais, Managing General Partner of lead investor Indico Capital. "This

26 investment will allow us ___ (make) significant progress and penetrate the market effectively,”

27 says Carlo Fedeli, the co-founder and Chief Executive of FlexSea.

Cancer therapies are getting a makeover

By Vanessa Chalmers, Health Features Editor

Cancer is no longer a death sentence when diagnosed, thanks to the ongoing emergence of treatments that can extend lives as well as better detection methods to find the disease earlier.Scientists have learned a lot about the immune response to cancer and are now harnessing it.When we hear the word vaccine, we typically think of it as preventing disease.But in this case, vaccines are being used as a treatment. Once injected they train the immune system to recognise and fight cancer cells. The body itself is recruited to kill the cancer, rather than relying on medicines.The process leaves healthy cells untouched, unlike chemotherapy, which kills healthy tissue and causes debilitating symptoms. NHS England's national cancer director, Dame Cally Palmer, said cancer vaccines being trialled could mark a huge step in treating the disease.There are also personalised vaccines which are designed specifically for an individuals cancer, based on their genetics.The challenges with personalised vaccines and other hugely advanced cancer therapies is they are very expensive to develop - and the question is whether the NHS will be able to afford such therapies when they come to fruition.

The enduring joy of Golden Girls: a wildly sassy sitcom that will always cheer you up

A comedic masterclass with the best sitcom theme song of all time, Golden Girls pulled back the curtains on ageing and dealt with big-ticket issues.

A zinger-infused maelstrom of shoulder pads, pastels and perms. Rattan furniture, DayGlo linen and Formica. There’s such a distinctive look, feel and vibe to The Golden Girls, the iconic sitcom that ran from 1985 to 1992, scooping up 68 Emmy nominations and 11 wins in the process. The brainchild of producer Susan Harris, the show spawned several acclaimed spinoffs and became an enduring work of high camp in the process.

The premise? Three older women decide to live together: the stern, witty ex-teacher Dorothy Zbornak (Bea Arthur), the sweet but fantastically dense Rose Nylund (Betty White) and southern hornbag Blanche Devereaux (Rue McClanahan). At first it’s a matter of convenience, but before long, they become fast friends. During the pilot they’re joined by a fourth: Dorothy’s mother Sophia Petrillo (Estelle Getty), a nitpicky little shrew whose ability to cockblock our heroines saw her gradually become the Scrappy-Doo of the house. (Don’t @ me, Goldies, you know I’m right.)

For a comedy that primarily took place within a Floridian kitchen, The Golden Girls boasted some serious talent. The four leads were all astoundingly adept at their craft.

The golden girls themselves proved that the family you make is sometimes stronger than the one you’re born with. Dorothy, Rose and Blanche feel, at times, aged out of their previous lives. Careers, spouses, the world: all seem to be pushing them away. But the girls are proof that you can – and should – forge new bonds, even if it seems like your old life is done for. That you can make a new family, even if your old one rejects you.

The Golden Girls pulled back the curtains on ageing, showing the ways in which old people can be flawed, passionate, monumentally stupid, brave – even at times, almost heroically horny. And it did so with an almost reckless willingness to be as wildly funny as it possibly could.

The show ended up doing what many sitcoms do: use antagonism as heat to push the plot forward. It takes truly hack writers to defend needless antagonism as the only source of fuel to propel a story (I’m looking at you, post-Sorkin West Wing). The last two seasons of The Golden Girls aren’t terrible, but Sophia morphs from an old lady without boundaries to an ancient sociopathic prankster. But even with this odd acceleration towards a caricatured sitcom event horizon, the show still manages to roll out the hits. The two-part finale, written by Mitch Hurwitz (the creator of Arrested Development) and starring Leslie Nielsen as Dorothy’s love interest, ranks as some of the best in the show’s history.

It also has – and I cannot stress this enough – the best sitcom theme song in the history of sitcom theme songs. In 2023, there are few things that will haul you out of whatever psychic muck you find yourself in than whacking on an episode of The Golden Girls. I promise you, once the credits roll, you’ll find yourself lying on the lanai in your mind, feeling somehow much lighter than you did before.

Read the text to answer the question from.

It happens that the publication of this edition of the Oxford Advanced Learner’s Dictionary comes 250 years after the appearance of the first comprehensive dictionary of the English language, compiled by Samuel Johnson. Much has changed since then. The English that Johnson described in 1755 was relatively well defined, still essentially the national property of the British. Since then, it has dispersed and diversified, has been adopted and adapted as an international means of communication by communities all over the globe. English is now the name given to an immensely diverse variety of different usages. This obviously poses a problem of selection for the dictionary maker: which words are to be included in a dictionary, and thus granted recognition as more centrally or essentially English than the words that are left out?

Johnson did not have to deal with such diversity, but he too was exercised with this question. In his Plan of an English Dictionary, published in 1747, he considers which words it is proper to include in his dictionary; whether ‘terms of particular professions’, for example, were eligible, particularly since many of them had been derived from other languages. ‘Of such words,’ he says, ‘all are not equally to be considered as parts of our language, for some of them are naturalized and incorporated, but others still continue aliens...’. Which words are deemed to be sufficiently naturalized or incorporated to count as ‘parts of our language’, ‘real’ or proper English, and thus worthy of inclusion in a dictionary of the language, remains, of course, a controversial matter. Interestingly enough, even for Johnson the status of a word in the language was not the only, nor indeed the most important consideration. For being alien did not itself disqualify words from inclusion; in a remark which has considerable current resonance he adds: ‘some seem necessary to be retained, because the purchaser of the dictionary will expect to find them’. And, crucially, the expectations that people have of a dictionary are based on what they want to use it for. What Johnson says of his own dictionary would apply very aptly to The Oxford Advanced Learner’s Dictionary (OALD): ‘The value of a work must be estimated by its use: It is not enough that a dictionary delights the critic, unless at the same time it instructs the learner...’.

The New Colossus

by Emma Lazarus Not like the brazen giant of Greek fame, With conquering limbs astride from land to land; Here at our sea-washed, sunset gates shall stand A mighty woman with a torch, whose flame Is the imprisoned lightning, and her name Mother of Exiles. From her beacon-hand Glows world-wide welcome; her mild eyes command The air-bridged harbor that twin cities frame. "Keep, ancient lands, your storied pomp!" cries she With silent lips. "Give me your tired, your poor, Your huddled masses yearning to breathe free, The wretched refuse of your teeming shore. Send these, the homeless, tempest-tost to me, I lift my lamp beside the golden door!" Considering the text above, judge the following excerpts:

The Times They Are A-Changin' - By Bob Dylan

Come gather 'round, people

Wherever you roam

And admit that the waters around you have

grown

And accept it that soon you'll be drenched to the

bone

If your time to you is worth saving

Then you better start swimmin' or you'll sink like

a stone

For the times, they are a-changin'

Come writers and critics who prophesize with

your pen

And keep your eyes wide, the chance won't

come again

And don't speak too soon, for the wheel's still in

spin

And there's no tellin' who that it's namin'

For the loser now will be later to win

For the times, they are a-changin'

Come senators, congressmen, please heed the

call

Don't stand in the doorway

Don't block up the hall

For he that gets hurt will be he who has stalled

The battle outside ragin'

Will soon shake your windows and rattle your

walls

For the times, they are a-changin'

Come mothers and fathers

Throughout the land

And don't criticize what you can't understand

Your sons and your daughters

Are beyond your command

Your old road is rapidly aging

Please get out of the new one if you can't lend

your hand

The line, it is drawn

The curse, it is cast

The slow one now will later be fast

As the present now will later be past

The order is rapidly fading

And the first one now will later be last

For the times, they are a-changin'

For the times, they are a-changin'

Imagine a world where dental crowns, bridges, and even braces can be custom‑made within hours. This vision is now a reality, thanks to 3D printing technology. Dentists in Robstown and around the globe are utilizing 3D printers to create precise and tailored dental prosthetics. By using digital impressions, dentists can design prosthetics that perfectly match the patient’s oral anatomy. This not only reduces production time but also enhances the overall quality and fit of the dental devices.

The philosopher Jeremy Bentham was regarded as the founder of utilitarianism and a leading advocate of the separation of church and state, freedom of expression, and individual legal rights. Furthermore, the “panopticon” is a type of institutional building that has long dominated Bentham’s legacy. As a work of architecture, the panopticon allows a watchman in a central tower to observe occupants of surrounding cells without the occupants knowing whether or not they are being watched. As a metaphor, the panopticon was commandeered in the latter half of the 20th century as a way to trace the surveillance tendencies of disciplinarian societies. Is it still a useful way to think about surveillance today?

The French philosopher Michel Foucault used the idea of the panopticon as a way to illustrate the proclivity of disciplinary societies to subjugate its citizens. He describes the prisoner of a panopticon as being at the receiving end of asymmetrical surveillance: “He is seen, but he does not see.” As a consequence, the inmate polices himself for fear of punishment.

The parallels between the panopticon and surveillance cameras may be obvious, but what happens when you step into the world of digital surveillance and data capture? Unlike the panopticon, citizens don’t know they are being watched. Jake Goldenfein, from the University of Melbourne, tells me it’s important to remember the corrective purposes of Bentham’s panopticon when considering it as a metaphor for modern surveillance. “The relevance of the panopticon as a metaphor begins to wither when we start thinking about whether contemporary types of visuality are analogous to the central tower concept. For example, whether this type of visuality is as asymmetrical, and being co-opted for the same political exercise.” In the panopticon the occupants are constantly aware of the threat of being watched — this is the whole point — but state surveillance on the Internet is invisible; there is no looming tower, no dead-eye lens staring at you every time you enter a URL. There may not be a central tower, but there will be communicating sensors in our most intimate objects.
