Scientists discover 'Olo': a new color beyond the naked human eye
Listen to article
A team of scientists from the University of California, Berkeley, and the University of Washington have reported the discovery of a new color, 'olo,' which cannot be seen by the naked eye.
The hue, described as a deeply saturated teal, was revealed through the use of advanced laser technology.
The color was made visible using a technique known as 'Oz,' a method that stimulates the photoreceptors in the human eye with laser pulses.
The breakthrough was achieved after researchers used the Oz technology to target individual photoreceptors in the eye, specifically the M-cones, which are responsible for detecting green wavelengths.
The experiment was conducted with five participants who were able to perceive olo after exposure to the laser stimulation.
While the color is not new in a physical sense—existing beyond the typical spectrum of human vision—it has never been seen by humans before.
The technology, which employs highly stable laser microdoses, is currently used for eye disease research, and researchers are exploring its potential applications for treating color blindness.
The color olo has been described as a vibrant blue-green, similar to teal but with unprecedented saturation. It cannot be rendered on current digital displays or virtual reality systems due to its unique properties.
The discovery has ignited discussions about the boundaries of human perception and the potential for future advancements in visual technology.
Researchers are also considering whether the technique could eventually aid those with color blindness by directly stimulating the correct photoreceptors in their eyes.
However, the miniaturization of this technology for broader use remains a distant goal.

The future is now:The future is now: PHD students develop headphones capable of translating languages in real-time
Listen to article Researchers at the University of Washington have unveiled a prototype headphone system that could transform global communication by translating multiple languages and speakers in real time. Dubbed Spatial Speech Translation, the system uses commercially available components to capture and translate ambient conversations. The device can detect and isolate several voices in a noisy environment, translate each speaker's language simultaneously, and relay the result back to the listener within seconds. Developed by the university's Mobile Intelligence Lab, the prototype combines Sony SH-100XM4 noise-cancelling headphones with Sonic Presence SP15C binaural microphones—devices that record audio in a way that mimics human hearing. Breaking Language Barriers: Real-Time Multilingual Translation Headphones Researchers at the University of Washington have developed prototype headphones capable of real-time translation of multiple speakers in various languages. Utilizing spatial audio and AI, these headphones… — Chubby♨️ (@kimmonismus) May 19, 2025 These microphones send audio feeds to a connected mobile device, where neural network models process and translate the input. The translated dialogue is then delivered to the user through the same headphones with a slight delay. Tests show that users preferred a delay of 3–4 seconds to minimise errors, though the system can respond in as little as 1–2 seconds. 'Our algorithms work a little like radar,' said lead researcher Tuochao Chen, a doctoral student at the Paul G. Allen School of Computer Science & Engineering. 'They scan the environment in 360 degrees, continuously identifying whether there's one speaker or several, and adapting in real time," he added. The system currently supports Spanish, French, and German, but the team hopes to expand its capabilities to around 100 languages. It also adjusts dynamically as the user turns their head or moves through a space, maintaining focus on individual conversations. Senior researcher Shyam Gollakota said the translation tool is part of a broader effort to 'break down language barriers between cultures.' The team has also made the software powering the device open source, encouraging further innovation. While still in the prototype stage, the technology represents a significant step forward in real-time multilingual communication. If fully developed, the system could have wide-ranging applications in travel, diplomacy, and international business. A demonstration video of the headphones in use is available on the University of Washington's official website, with all relevant details of the technology also available on a separate webpage.

Leveraging fintech and telecom to bridge Pakistan's insurance gap
Listen to article As Pakistan stands at the crossroads of digital transformation, a critical gap in the current financial infrastructure becomes increasingly apparent: our insurance penetration remains just 0.8% of the GDP. This means millions of Pakistani families are vulnerable to financial shocks from health emergencies, accidents, or loss of life. This vulnerability is further underscored by recent increases in poverty. The World Bank, in its report titled "Poverty Projections for Pakistan," noted a 25.3 percent poverty rate in 2024, up by 7 percentage points from 2023, pushing an additional 13 million people into poverty. Within this projected increase, poor households face disproportionately higher welfare losses and get pushed deeper into poverty. Two emerging markets offer compelling insights into insurance sector transformation. India, with its vision of "Insurance for All by 2047," has made significant strides in expanding insurance coverage. While still below the global average, India's life insurance penetration stands at 2.8%, with non-life insurance reaching 1% of GDP. Their insurance regulator, IRDAI, has been instrumental in this growth, implementing innovative strategies such as creating Bima Sugam, a digital platform for insurance that simplifies product selection, and repealing over 1,000 outdated regulations. Simultaneously, Kenya provides another instructive model. Through mobile-based microinsurance platforms like M-Tiba, the country has dramatically increased insurance access, particularly in rural areas. These digital solutions have enabled millions of low-income Kenyans to access affordable health insurance through mobile technology. In this global context, we must ask ourselves: what is Pakistan's roadmap to universal insurance coverage, and how can we leverage our growing fintech and digital connectivity ecosystem to achieve this ambitious goal? The challenges are significant but not insurmountable. In a country where traditional insurance has long been viewed with skepticism and perceived as a luxury rather than a necessity, we need a paradigm shift in how insurance products are designed and distributed. Our current life insurance penetration remains stagnant at 0.5%, with non-life insurance at an even lower 0.3%. Jazz has been at the forefront of insurtech innovation in Pakistan, with its pioneering efforts playing a crucial role in bridging the insurance gap. Achieving a remarkable milestone of 8.6 million active insurance policies, Jazz has seamlessly integrated insurance into its bundles, offering customers not only affordable GSM benefits but also essential health and handset coverage. Jazz also offers customized bundles with a built-in component of insurance meeting the specific needs of women's health-related concerns. The digital operator has pioneered several groundbreaking initiatives in the insurance space, particularly through its FikrFree platform, which serves as Pakistan's answer to India's PolicyBazaar. The FikrFree Insurance and Healthcare Marketplace represents a significant evolution in Pakistan's digital insurance landscape. This comprehensive platform brings together over 30 insurance products from multiple service providers, ranging from health and handset insurance to bike coverage. What sets FikrFree apart is its holistic approach to customer well-being, integrating healthcare services such as e-pharmacy and online video consultations with over 2,000 doctors. The introduction of the FikrFree Sehat Card further demonstrates this commitment, offering retail customers six months of coverage including hospitalization benefits and accidental OPD care. One particularly innovative aspect of Jazz's insurance strategy is its AI-powered approach to handset insurance, addressing a critical need in a market where phone snatching is a persistent issue. Leveraging Fikrfree AI, the system detects handset changes in real-time and proactively offers tailored insurance offers. Some tariffs even come with built-in handset insurance, covering damage, theft, and screen breakage. This smart protection ensures that customers can quickly recover from device loss or damage without facing significant burden. Continuing this legacy of innovation, JazzCash as one of the largest embedded insurance distributors in Pakistan, exemplifies the transformative potential of fintech in expanding insurance access. Currently distributing more than 600,000 policies daily through everyday transactions like digital loans, utility bill payments, and motorway toll top-ups, JazzCash has ambitious plans to help insure 10 million unique lives by the end of 2027 through partners, representing a significant progress towards universal coverage. One of the most impactful initiatives in this space is JazzCash's approach to responsible nano-lending. Recognizing that small-ticket loans often target financially vulnerable individuals, JazzCash has pioneered an embedded insurance model that automatically provides free life and health insurance coverage for digital loans above PKR 6,000. This is significant because a large portion of the 600,000 average daily insurance policies distributed in 2024 were tied to these digital loans. This ensures that in case of an unforeseen event, such as the borrower's death, their family is not burdened with outstanding liabilities. This model not only expands insurance penetration but also sets a new benchmark for responsible lending in Pakistan's digital financial landscape. Thanks to initiatives like these, insurance doesn't have to be about a haggard agent scaring you into buying a premium by listing all the bad things that could happen to you. Now, it can be as easy as a pop-up asking you if you would like to insure your journey for Rs.140 after you pay your toll tax on the motorway. The path to universal insurance coverage in Pakistan requires addressing several critical challenges. First, we must prioritize financial literacy and insurance awareness. Many Pakistanis remain unaware of insurance benefits or harbor misconceptions about its compatibility with religious beliefs. In India's case, life insurance remained a low priority for Indian consumers until the onset of the Covid-19 pandemic. Risk awareness grew during that period, and customers became accustomed to purchasing things digitally. With mobile teledensity at 80% and broadband coverage of around 60%, insurance providers must develop simple products and leverage digital channels to educate and acquire customers. Second, our regulatory framework must evolve to encourage innovation while ensuring consumer protection. Drawing inspiration from both India's regulatory sandbox approach and Kenya's mobile-first strategy, we can create an environment that fosters insurance innovation. The recent success of micro-insurance products, with premiums as low as Rs. 10 daily, proves that affordability and accessibility can coexist with commercial viability. Third, we must address our market's unique characteristics. Pakistan needs to leverage its growing digital payment infrastructure and provide both conventional insurance and Takaful options. The availability of Shariah-compliant alternatives is crucial for widespread adoption in our market. Fintech startups and insurance companies must work together to ensure that products are not only accessible but also tailored to meet the diverse needs of consumers, particularly in underserved rural areas.

M&S cyberattack by Scattered Spider halts online orders, disrupts operations
Entrance to a Marks and Spencer store is pictured at the Oxford Street, in London An entrance to a Marks and Spencer store is pictured at the Oxford Street, in London, Britain July 2, REUTERS Listen to article Marks & Spencer (M&S), the UK retail giant, has suffered a major cybersecurity breach attributed to the notorious 'Scattered Spider' ransomware group, leading to widespread operational disruptions. The cyberattack, confirmed last week, has forced M&S to suspend all online orders across its UK, Ireland, and some international platforms. The breach has also disrupted contactless payments, gift card transactions, and click & collect services. According to sources, the attack began in February when hackers stole sensitive credentials by extracting the file, the core of Microsoft Active Directory. This allowed lateral movement across the network. On April 24, the attackers deployed the DragonForce ransomware, targeting M&S's VMware ESXi infrastructure, effectively crippling virtual machines and backend systems. M&S has enlisted the help of cybersecurity firms including CrowdStrike, Microsoft, and Fenix24 to manage the breach and recover operations. Though the company has remained tight-lipped on technical details, industry experts identify Scattered Spider—also known as Octo Tempest and UNC3944—as the likely perpetrators. The group is known for sophisticated social engineering, phishing, MFA bombing, and SIM swapping techniques. Analysts warn that M&S's brand reputation has taken a hit. With roughly one-third of its UK clothing and home goods sales occurring online, the timing—coinciding with seasonal shopping surges—could translate into lost market share. While contactless payments have resumed and some click & collect services are functional, many customers remain frustrated by ongoing issues and lack of clear updates. Despite the setback, retail experts believe M&S's quick acknowledgment and active response may limit long-term damage. However, cybersecurity professionals caution that the evolving tactics of ransomware groups like Scattered Spider underscore the urgent need for stronger digital defenses across all sectors.
