British Opal gets her hearing back with gene therapy

18-month-old Opal Sandy has regained her hearing after a unique ‘gene therapy’ operation. The girl is the first in the world to undergo the procedure.

Opal Sandy was born deaf as a result of auditory neuropathy, a condition that disrupts nerve impulses from the inner ear to the brain and can be caused by a faulty gene. Opal’s five-year-old sister, Nora, has the same type of deafness, but is helped by a cochlear implant that sends electrical signals to the auditory nerve, bypassing the defective parts of the ear.

It was a big decision for parents Jo and James, from Owfordshire, to have their daughter operated on.

– It was really scary, but I think we’d been given this unique opportunity, her mother said in an interview with the British state broadcaster BBC.

During the operation, the girl was given an infusion containing a copy of her missing gene. After the 16-minute operation, the girl was able to hear.

– I couldn’t really believe it, Opal’s mother Jo Sandy told The Guardian. It was … bonkers.

The operation is the first of its kind and was performed at Addenbrooke’s Hospital, part of the Cambridge University Hospitals NHS Foundation Trust. Other deaf children are now being recruited for the operation and will be followed for five years.

Ear surgeon Professor Manohar Bance says these early results from the operation are “better than I hoped or expected”.

– We have results from [Opal] which are very spectacular – so close to normal hearing restoration. So we do hope it could be a potential cure, he says, adding:

– There’s been so much work, decades of work.

A second child recently underwent a similar operation at Cambridge University with good results.

It is now hoped that this type of gene therapy could be used for other types of deafness, as half of all hearing loss in children has a genetic cause. Today, most people, like Opal’s sister Nora, receive a cochlear implant, a device that needs to be replaced several times. But it is important to have the surgery as early as possible, before the age of three, when the brain is more adaptable.

Now that Opal’s hearing has been restored, her parents have other problems to deal with. Opal has a new hobby: banging cutlery on the table as hard as she can to make as much noise as possible.

Sweden stands out in new global mapping of economic power

Published 15 May 2025
– By Editorial Staff
Mark Zuckerberg, Jeff Bezos and Elon Musk are usually considered three of the richest - and most powerful - men in the world.

A new international database maps the world’s most economically influential power brokers – and Sweden stands out. In contrast to many other countries, outstanding academic credentials are rarely required to reach the top of the financial ladder here.

Who really controls the global economy? A group of 70 researchers has collected data on over 3,500 people from 16 countries who together account for a majority (54 percent) of the world’s GDP.

The results, presented in the new World Elite Database (WED), reveal both global similarities and national differences in terms of age, education, and background, with Sweden deviating significantly in one respect. Here, only five percent of the richest power holders have a doctorate the lowest figure among all countries surveyed.

These are CEOs and board members of large companies, those with the greatest wealth and people with the power to regulate the economy. The median age varies greatly: the American financial aristocracy is the oldest (62), while China and Poland have the youngest top echelons (55).

Place of birth also differs: in China, almost half of the elite were born in small villages, but only 1 percent were born abroad. In the UK, on the other hand, 45 percent of the richest were born outside the country, often in India.

– It is interesting to see that as much as 20 percent of the UK’s economic elite comes from the country’s former colonies, notes Håkan Johansson, professor at Lund University and one of the researchers behind WED.

“Not highly valued in Sweden”

Sweden’s economic ruling class is distinguished by its low level of education, even when compared to neighboring countries. In Germany, just over a third of those with economic power have a doctorate or equivalent, compared to one in twenty power holders in Sweden.

– It is quite clear that a doctorate is not highly valued in Sweden and is not necessary to reach the top of society, Johansson continues.

A master’s degree is most common among the elite, except in Argentina, Italy, and the UK, where a bachelor’s degree is more common. Those who have inherited their wealth have the lowest level of education.

To become part of the financial elite, a degree in economics is otherwise the most common route – except in China and Finland, where it is more common for those who have reached the “top” to be civil engineers.

In the UK, Poland, and Switzerland, law and the humanities are also highly valued at least 20 percent of the “top tier” have studied these subjects compared to less than 10 percent in the Nordic countries.

“Have enormous power”

Some may wonder why it is important for researchers to map the backgrounds and qualifications of those in power, but Håkan Johansson points out that this is a group that has an extremely large influence and that it is important to try to understand how and why they make their decisions.

– Economic elites are interesting because they have enormous power. They influence people’s working conditions, countries’ prosperity, and financial development. This is the first database of its kind, and many researchers will use it in their studies.

One example of research that would be interesting to do using the database is to link it to what economic elites actually do with their power, for example in studies of the climate impact of elites, he continues.

The World Elite Database (WED) is the result of an international collaboration between some 70 researchers from Chile, Denmark, Italy, France, Finland, China, Norway, Poland, Portugal, Russia, Sweden, Switzerland, the United Kingdom, Germany and the United States.

The database is currently only available to researchers and contains more than 3,500 names from 16 countries that together account for 54% of the world's gross domestic product.

The first scientific article based on the material was published recently in the British Journal of Sociology.

Robotic insects to revolutionize agriculture

Published 6 May 2025

An early version of the robotic insect from MIT.

Researchers are developing different types of robotic insects. The idea is that they will revolutionize agriculture when other pollinators are threatened with extinction, but also to be able to engage in surveillance.

Today, a large proportion of the world’s pollinators, such as bees and butterflies, are heading towards extinction, with the UN estimating that nearly 35% are threatened with extinction globally. However, robotic insects are not intended to replace real insects, but rather to develop agriculture.

Pollination is critical to the entire food industry, as 75% of the world’s food grown depends on pollination. Researchers at the Massachusetts Institute of Technology (MIT) believe that with artificial pollination, using robotic insects, farmers could in the future grow fruit and vegetables in multi-storey warehouses. This, in turn, is said to increase yields while reducing some of the harmful environmental effects of farming.

For some time, researchers have been working on developing various robotic insects. Earlier versions of the robotic insect consisted of four identical units, each with two wings, combined into a rectangular unit about the size of a microcassette.

Now, much smaller and more durable robotic insects have been developed. The new robots can hover for about 1 000 seconds, which is more than 100 times longer than previously demonstrated. At the same time, they weigh about the same as a paper clip and can fly much faster.

– Compared to the old robot, we can now generate control torque three times larger than before, which is why we can do very sophisticated and very accurate path-finding flights, said researcher Kevin Chen in a press release.

The goal is to achieve a flight lasting longer than 10,000 seconds. They also want to improve its precision so that it can land and take off from a flower, which it currently cannot do.

Inspired by the crane fly

Researchers at Harvard University have also been working on developing robotic insects. RoboBee can fly, dive and hover like a real insect. The robot weighs only one-tenth of a gram and has a wingspan of three centimeters. The idea is that RoboBee could be used for artificial pollination, but also for surveillance and rescue operations.

However, researchers have long struggled to land it effectively, but now they have found a solution. Taking inspiration from nature, a seemingly graceful landing has been upgraded for RoboBee.

The crane fly spends much of its short life landing and taking off, and it has a strong ability to cushion the landing using its long legs that almost act as shock absorbers. Since the robot’s size and shape were already similar to the crane’s, the researchers chose to develop the robot’s legs like the crane’s.

However, RoboBee is still unable to fly without external energy and is wired. The idea now is to continue developing the robot.

– The longer-term goal is full autonomy, but in the interim we have been working through challenges for electrical and mechanical components using tethered devices, said researcher Robert Wood, from Harvard, in a press release.

New endocrine-disrupting chemicals detected in Swedish blood samples

Published 3 May 2025
– By Editorial Staff
It is still difficult to assess the extent of the negative health effects of environmental pollution.

A new group of environmental pollutants has been discovered in the blood of Swedes. Some of the substances may have a negative impact on fertility and may also be endocrine disruptors.

So-called synthetic phenolic antioxidants (SPAs) have been found in 30 blood donors in Stockholm, confirmed a study from Stockholm University.

SPAs are found in food packaging, chewing gum, clothing and skin care products, where they are often used to increase the durability of materials. Some of these substances are on the EU’s so-called candidate list, i.e. a list of substances of very high concern. This is because some of the substances can be endocrine disruptors and also negatively affect fertility.

Previous studies from China and the US have shown that the substances are present in both humans and the environment, and some in high concentrations. However, this is the first time it has been detected in the blood of Swedes. The levels are comparable or even higher than the levels of the more well-known PFAS substances, according to researchers.

This study is a first indication that we have a high exposure to SPAs also in Sweden. Studies on more individuals in different parts of Sweden need to be done to understand the extent of the problem, says researcher Josefin Engelhardt in a press release.

“Don’t know what the consequences will be”

One reason why SPA levels may have been missed in the past is because of the great care required when analyzing blood. Since SPAs are used in plastics and laboratory materials, it is important to be sure that it is the blood levels that are being measured and not substances added during sample collection. However, new methods have now been developed to analyze SPAs in blood.

The researchers say that we now need to find out where SPAs come from and also investigate their health effects, to best prevent them from spreading and affecting people and the environment.

We don’t know what the consequences of long-term exposure to these substances will be, but the fact that they are present in high levels in the blood is sufficient to act and reduce the levels in accordance with the Swedish Parliament’s environmental quality objective ‘A non-toxic environment’, says Engelhardt.

Young adults in Sweden feel shame about scrolling habits

Published 25 April 2025

Young adults in Sweden often feel ashamed of their mobile phone addiction and experience themselves to a high degree that they have an addictive behavior, according to research from the University of Gothenburg.

The study looked at how people between the ages of 20 and 35 view their own mobile phone use. It emerges that many consider themselves to be addicted and find it difficult to let go of their cell phones.

André Jansson, one of the researchers behind the study, believes that a form of culture has been created where it has become associated with social status to have the ability to reduce screen time and have control over their mobile phone use, something that many people feel they are unable to live up to in reality. Many also feel that they are wasting their time scrolling and ashamed that they cannot control it.

– When you can’t live up to that ideal, it creates a moral dissonance, you don’t use your smartphone in the way you would like to, Jansson told the state channel SVT.
