Quick answer: The best math apps for kids depend on your child’s age and what you need. For story-driven practice that keeps kids ages 5 to 10 coming back on their own, MathHero is the strongest pick. For the earliest counting and number recognition, Khan Academy Kids and Moose Math fit better. For skills beyond arithmetic like fractions and geometry, DragonBox is worth a look. Below, each app is broken down by who it actually helps, what it costs, and where it falls short.

Vision is so important, yet, according to a CDC study, in 2017, about 40% of the population at risk for vision loss did not see an eye doctor. Meanwhile, nearsightedness, a condition that can be slowed with proper healthcare, has increased from 25% to 42%. So why are people skipping ophthalmologist visits? Cost is a significant factor. Healthcare costs are rising, and so are insurance premiums. But there are ways to make care more affordable.

again, maths is the most popular A-level subject. There were 115,380 entries in the subject in 2026, an increase of 3.9% from 2025. Further maths AS-level entries enjoyed an 8.5% increase from 2025 as well. Moreover, recently published data from university admissions service Ucas for the 2026 application cycle showed a marked 11% increase in applications to study mathematical sciences at university.

The “bible” of clinical psychiatry – the DSM, short for the Diagnostic and Statistical Manual of Mental Disorders – is one of the most popular psychiatry reference books around the world. Clinicians use it to diagnose patients and scientists use it to guide research. Despite its wide impact, the DSM has never integrated biology in its diagnoses of mental illness.

Ten percent of the population gets its information primarily from chatbots —conversational agents powered by artificial intelligence (AI)—according to a survey of 93,000 people worldwide for the Reuters Digital News Report 2026. Furthermore, when participants were asked about their preferences, 46% said they seek out sources without a bias (i.e., perceived as objective).

Leadership development programs – what doesn’t work? (Part 1) was published last week and focuses on introducing the survey about leadership programs that I did a while ago. It discussed what respondents liked and disliked about the programs in which they participated. This second post reports back on one of the final the survey questions, which asked about what an ideal leadership program might look like. I then close out the post with some of my considerations for an effective program.

For an experienced reader, recognising the words on this page feels effortless. Yet, evolutionarily speaking, your brain shouldn’t be able to read. Reading has existed for too short a time to have shaped a dedicated centre in the brain. Therefore, the brain has to learn to read using systems that evolved for other purposes. But it has long been unclear exactly which systems it recruits to do so and how.

The Trump administration is revising a visa rule for international students that in part determines how long, and under what conditions, they can stay in the country. The change sounds technical. Its effects are not. Beginning Sept.

Most researchers are told early on to keep a research journal. The journal is a place to record stuff – ideas, possible lines of inquiry, potential analytic processes, quotes you don’t want to forget, reflections and responses to readings. Journals can be digital or material. A lot of what ends up in an old-fashioned analog journal takes the form of hand-written jottings, rather than formally constructed entries. It’s a line or two about something odd in a transcript.

Most people picture a medical error as a single dramatic moment. A wrong medication. A missed diagnosis. A surgery that goes sideways. But researchers who study patient safety say the real story often starts after that moment, when the patient goes home and tries to make sense of what happened. Many stay silent. They do not file a complaint. They do not ask questions at their next appointment. They just carry it.
