AI spurs ‘revolution’ for some visually impaired people

AI has helped visually-impaired Louise Plunket

“AI has revolutionised my daily life,” says Louise Plunkett from Norwich.

Ms Plunkett has a genetic eye condition called Stargardt disease, a rare condition that causes progressive vision loss, which she says, “impacts everything I do”.

“I can’t recognise people, even my own husband or my children. When my children were younger, I used to have to teach them how to come to me when I met them at the school playground.”

Ms Plunkett is comfortable with digital tools – her business advises companies on how to ensure their online content is suitable for the visually impaired community.

She has used services like Alexa, Google Home and Siri for years, helping with tasks like setting alarms and weather checks.

Now she is finding an assistant called Be My AI useful.

The app uses ChatGPT to generate and then read out detailed descriptions of pictures.

“I’m quite a stubborn person,” says Ms Plunkett. “I don’t like asking for help or admitting I need help, so using the AI tool is useful for things when other humans aren’t around.”

She says she might use it to check which is the female toilets, or read the ingredients on food packaging, or read a letter.

However, she feels that AI can sometimes be hit or miss. “The downside with AI is that sometimes it gives you too many details. You sometimes just want the basic information of what is in front of you, but it will go above and beyond, and offer up mood and emotions.

“For example, it might say ‘a swirling carpet evoking memories of times gone by’. It feels like it is one step too far.”

Be My AI was developed by Danish firm Be My Eyes. Its original service put human volunteers in touch with its clients. Via mobile phones the volunteers would describe what was in front of the person with vision problems.

However, some of its 600,000 users are switching to their AI tool for help, says Jesper Hvirring Henriksen, chief technology officer.

“We have a woman who was one of our first users 10 years ago, and within the first six months [of releasing Be My AI], she did more than 600 image descriptions.”

He’s also discovering people are using the app in ways they hadn’t imagined. “We’re finding people using it to check pictures that have been sent to them on WhatsApp groups,” he says.

“Maybe they’re not going to call another human each time to ask them about a picture sent on a WhatsApp group, but they use AI.”

Be My Eyes connects volunteers with the visually impaired

As for where it might go in the future, he says live streaming video – with the tech describing buildings and movements around them – might be an area they move into. “This is going to be a gamechanger. It’s like having a little person in your shirt pocket all day telling you what is going on.”

Be My Eyes, which is free to users, makes money by signing up companies to its paid-for directory service where they can provide information and numbers to the blind and low-vision community.

Mr Henrikson says AI won’t replace the need for human connection.

“At Be My Eyes, people are still choosing to call a volunteer too. The blind population in the Western world are generally not young when they start to experience vision loss… it’s more skewed towards the elderly population and this [AI] might add a later extra of complexity. Humans are faster and potentially more accurate.”

Other firms also have products to help those visually impaired.

Featuring a voice assistant, WeWalk is an AI-powered cane that detects obstacles and offers accessible navigation and live public transport updates.

Connecting to a smartphone app with in-built mapping, it can tell users where places of interest are, including where the nearest café is in over 3,000 cities.

“The cane is very important for us, it helps navigation and is a very important symbol as it shows our independence and automacy,” says Gamze Sofuoğlu, WeWalk’s product manager.

“Our latest version helps users navigate the cane through voice commentary, for example when say take me home or the nearest café it can starts navigating, and you can get information about public transport. You don’t need to touch your phone. It provides freedom for blind and low vision people.”

Ms Sofuoğlu, who is blind, says she has been using it in cities she has visited recently such as Lisbon and Rome.

Robin Spinks, head of inclusive design at the RNIB (Royal National Institute of Blind People), and who has low vision, is a huge advocate of AI – he uses AI most days.

For example, he turns to ChatGPT to assist with his workflow, giving him a summary of development in certain areas in relation to work, or even to help plan a paddle board trip, and to the Google Gemini AI tool to help him locate items.

Last year was all about conversational AI and Chat GPT, he says. Now he argues 2024 is the year of what he called “multimodal AI”.

He goes on to say: “That might be showing video and images, and being able to extract meaningful information and assist you in an exciting way.”

He points to Google Gemini. “For example, with that you can record meetings and it assists with you voice labels and an account of a meeting, it’s genuinely helpful and it’s about making people’s lives easier.”

Mr Spinks says AI has been transformational for people who are blind or low vision.

“I sympathise with people who are genuinely scared of AI but when you have a disability, if something can genuinely add value and be helpful that has to be a great thing. The benefits are too great to ignore.”

Hospice leaders warn hundreds of beds out of use

Hospice leaders warn hundreds of beds out of use

About 300 hospice inpatient beds are currently closed or out of use in England, hospice leaders have warned.

They say a lack of funding and staff are the primary reasons why some of England’s 170 hospices have had to close beds permanently or take them out of use.

Hospice UK, which represents the sector, is now calling for an urgent package of government funding to prevent further cuts. The Department of Health said it was looking at how to financially support hospices to ensure they are sustainable.

The debate over assisted dying has increased the focus on hospices, with some arguing that the priority should be raising the quality of end-of-life care to allow patients to make more informed choices.

Hospice leaders have been warning of a financial crisis for much of this year.

They argue that income from the health service has lagged behind rising costs, with some hospices announcing cuts to clinical jobs.

Only about a third of funding comes from the NHS – the rest has to be raised from donations, fundraising and charity shops.

For hospices, which provide both community and in-patient care, there is now increasing concern because of the prospect of higher employer national insurance contributions.

Hospice UK says about 300 beds are closed or out of use in England – out of a total of 2,200 – and the number is increasing.

The organisation has called on the government for £110m of new funding to prevent further cuts over the next year.

‘A huge cap’

Annette Alcock, Hospice UK’s director of programmes, said the way that hospices are funded and commissioned by the NHS is “acting as a huge cap on what they can do”, while also blaming “underlying pressures like staff shortages”.

She added: “If the government can act in both the short and long term to resolve these problems, these figures are clear evidence that hospices can do a lot more for patients, and a lot more for the NHS.

“That’s true out in the community too, where most of hospice care is actually delivered.

“With better funding and commissioning, hospices could provide so much more care where people most want it – at home.”

A Department of Health and Social Care spokesperson said: “The choices the chancellor made in the Budget allowed us to invest another £26bn in the NHS.

“We are looking at how we can financially support hospices next year to ensure they are sustainable.”

Health Secretary Wes Streeting has previously indicated that a finance package will be announced before Christmas.

Hospice leaders say about £100m would stabilise their balance sheets at least until the end of next year and cover the cost of higher national insurance contributions. But they add that it will take more than this to significantly improve the quality of care.

The awkward parallels between the Hunter Biden and Donald Trump convictions

The awkward parallels between the Hunter Biden and Donald Trump convictions

Donald Trump and Joe Biden may not have much in common. But when it comes to their connections to high-profile prosecutions, they have sounded a similar tune – even in the face of outcry from opponents and some in their own parties.

In announcing a “full and unconditional” pardon for Hunter Biden on Sunday night, Joe Biden condemned what he characterised as an unfair prosecution of his son.

“No reasonable person who looks at the facts of Hunter’s cases can reach any other conclusion than Hunter was singled out only because he is my son – and that is wrong,” Biden said.

The president’s criticisms of a politicised system of justice echoed those regularly lobbed by Trump – perhaps most conspicuously in the New York City case involving hush-money payments to adult film star Stormy Daniels. That indictment ultimately led to the former president’s conviction on multiple felony counts of falsifying business records to conceal campaign finance violations.

“What’s going on in New York is an outrage,” Republican Senator Lindsey Graham of South Carolina, a Trump confidante, said of the former president’s hush-money trial. “I think it’s selective prosecution for political purposes.”

What similarities are there between the cases?

The Hunter Biden cases and Trump hush-money case do have notable similarities – ones that have fuelled attacks on the judicial process.

Both were brought to court in 2024, years after the incidents in question. Trump’s payments to Daniels occurred in 2016. The handgun application on which Hunter Biden denied his drug use was from 2018, while his fraudulent tax returns were from 2016 to 2019.

Both cases took sharp twists after it seemed they would not reach trial. It appeared the New York Trump investigation would be dropped when Alvin Bragg was elected to replace Cyrus Vance as Manhattan attorney. A plea deal that would have resulted in Hunter Biden accepting guilt but serving no prison time collapsed at the last minute amid questions from the presiding judge.

Both also involved applications of existing law in novel or unusual circumstances.

The underlying campaign finance crimes in the Trump case were federal, not state, violations that US government attorneys had already chosen not to pursue. Rarely are gun-application cases like Biden’s prosecuted without a connection to more serious misdeeds. And his tax evasion violations were addressed through back-payment and fines – a resolution that typically avoids criminal charges.

In fact, Trump’s legal team drew explicit comparisons between the two cases in a legal filing on Tuesday that cited Hunter Biden’s pardon as reason to dismiss Trump’s New York conviction.

“President Biden argued that ‘raw politics has infected this process and it led to a miscarriage of justice,’” Trump’s lawyers wrote. “These comments amounted to an extraordinary condemnation of President Biden’s own [Department of Justice].”

“This case should never have been brought,” they concluded.

Watch: Americans divided over Biden’s pardon of son Hunter

What are the differences?

There are notable differences between the two cases, of course. Hunter Biden never held public office. And the New York hush-money case was just one of multiple prosecutions of the former president, several of which dealt with much more serious and recent alleged crimes. Trump didn’t distinguish between them, however, claiming all of the investigations of him were politically motivated “witch hunts” designed to damage his electoral prospects.

Differences aside, both Trump and the Bidens raised similar questions about whether politics unduly influenced their cases, even as Democrats insisted that the Trump trial was proper, and Republicans viewed the Hunter gun trial and tax evasion guilty plea as justice served.

According to Kevin McMunigal, a law professor at Case Western Reserve University and former assistant US attorney, the claim that politics affects prosecutorial decisions is largely inaccurate. He notes, however, that the public may not appreciate that there is a complicated calculus behind when or whether to charge criminal offences.

“Congress and state legislatures love to pass criminal statutes, and they rarely repeal them because of the politics involved,” he said. “Everyone wants to be tough on crime. You wind up with statute books that are full of crimes, many of which don’t get prosecuted.”

He adds that it is not common knowledge that these statutes are often ignored by prosecutors. “It’s kind of hard for people to get their heads around,” he said.

This lack of understanding could provide reason enough for those on both sides of America’s sharp political divide to perceive a double standard when it comes to the American system of justice – particularly when it involves high-profile cases involving government officials or their families, and especially when it is the politicians themselves who are stoking the fires.

What could Biden’s pardon mean for Trump?

Whether or not the indictments were an appropriate exercise of prosecutorial judgement, both Trump and Hunter Biden were convicted of their crimes.

Due to his pardon, Hunter Biden will face no consequences for that. And as Trump prepares to head back to the White House, it appears increasingly likely that the nature of his high office will protect him from a sentence for his conviction. It has already led to the federal cases against him being dropped.

Public perception of a double-standard for the wealthy and powerful may not be so off base.

American faith in the criminal justice department is being undermined, said John Geer, a political science professor at Vanderbilt University and head of its Project on Unity and American Democracy. He adds, however, that claims of selective prosecution amount to a “pebble thrown in a very large lake”, compared to the broader issues at play.

“Justice has never been blind,” he said. “There have been periods of time when it has been more even-handed than others, however.”

Recent developments, he says, reflect a growing public distrust in political institutions across the board – including Congress, the presidency and the Supreme Court.

Trump has capitalised on this distrust in institutions, railing against the government “swamp” and promising the kind of sweeping reforms his supporters believe more established politicians are unable or unwilling to deliver.

When taken in context, Trump’s ongoing complaints of political prosecutions, and Biden’s recent adoption of similar claims, are a reflection of a larger crisis of American faith in government – one that both politicians have taken advantage of when circumstances put them in uncomfortable legal terrain.

Biden’s use of Trumpian rhetoric to explain his exercise of presidential power to protect his son might only help the incoming president find more support to swing the wrecking ball at the institutions that Biden has long served and pledged to protect.

A team of scientists have identified a gene in poplar trees that enhances photosynthesis and can boost tree height. The study, “An orphan gene BOOSTER enhances photosynthetic efficiency and plant productivity,” is published in Developmental Cell, and was a collaboration between the Center for Advanced Bioenergy and Bioproducts Innovation at the University of Illinois Urbana-Champaign and the Center for Bioenergy Innovation at Oak Ridge National Laboratory.

Chloroplasts are the principal cell structures that house the photosynthetic apparatus converting light energy into the chemical energy that fuels plant growth. Specifically, the Rubisco protein captures carbon dioxide from the atmosphere. Scientists have for years been working on ways to boost the amount of Rubisco in plants for greater crop yield and absorption of atmospheric CO2.

“Historically, a lot of studies have focused on steady-state photosynthesis where every condition is kept constant. However, this is not representative of the field environment in which light can vary all the time,” said Steven Burgess, an assistant professor of integrative biology at Illinois. “Over the last few years, these dynamic processes have been considered to be more important and are not well understood.”

In the new study, the researchers focused on poplar since it is a fast-growing crop and a leading candidate for making biofuels and bioproducts. They sampled ~1,000 trees in outdoor research plots and analyzed their physical characteristics and to perform a . The team used the GWAS population to look for candidate genes that had been linked to photosynthetic quenching, a process that regulates how quickly plants adjust between sun and shade and dissipate excess energy from too much sun to avoid damage.

One of the genes, which the researchers named BOOSTER, was unusual because it is unique to poplar and although it is in the nuclear genome contains a sequence which originated from the chloroplast.

The team discovered that this gene was able to increase the Rubisco content and subsequent photosynthetic activity, resulting in taller polar plants when grown in greenhouse conditions. In field conditions, scientists found that genotypes with higher expression of BOOSTER were up to 37% taller, increasing biomass per plant.

The team also inserted BOOSTER in a different plant, Arabidopsis, or thale cress, resulting in an increase in biomass and seed production. This finding indicates the wider applicability of BOOSTER to potentially trigger higher yields in other plants.

“It is an exciting first step, although these are small-scale experiments, and there is a lot of work to be done, if we can reproduce the results on a large scale, this gene has the potential to increase biomass production in crops,” Burgess said.

Next steps in the research could encompass testing in other bioenergy and , with researchers recording plant productivity in varying growing conditions to analyze long-term success. They will also be investigating the other genes that were identified in the GWAS study that could contribute to crop improvement.
