The fact that food prices in Australia have soared this year is not new news for most people. Key points: Deakin University research shows lettuce, broccoli and tomato prices have soared Amid other cost of living pressures, more people are seeking help with food costs There are calls for a national strategy to ensure Australians can access healthy food But tracking data for 28 specific grocery items over the past few years shows which product prices have gone up the most, which have fallen and which have remained stable. Figures from Deakin University’s Institute of Health Transformation support the most eye-catching increase – the skyrocketing price of lettuce. Data shows lettuce has jumped 150 percent in 12 months, up from the national average of $2 per head for icebergs last year to $5 in 2022. All kinds of leafy greens have disappeared from store aisles in recent months, including broccoli, which had the second biggest jump. It jumped from $6.90 per kilo in June last year to $11.90

Many of us are taught from an early age that vegetables are nutritional superstars, and we should eat at least five servings per day. Key points: Experts believe time and cost constraints are factors why some people abandon their healthy eating habits Floods and prolonged wet weather across eastern Australia have sent the prices of some vegetables such as iceberg lettuce skyrocketing A Tasmanian nonprofit has started a new project to provide healthy lunches to students in 15 schools across the state But a recent Australian Institute of Health and Welfare (AIHW) report found that most adults don’t eat the recommended amounts of vegetables. In fact, less than one in 10 adults eat enough vegetables each day: 96 percent of men and 87 percent of women don’t eat enough vegetables. So why did it get so bad? There are several reasons why people don’t include enough vegetables in their diet, and experts believe our busy lifestyles are one of them. “Vegetables are not a comfort food, if you’re o

The human genome is littered with “selfish genetic elements”, which do not appear to benefit the host, but only seek to reproduce. Selfish genetic elements can wreak havoc by, for example, distorting sex ratios, impairing fertility, causing dangerous mutations, and potentially even causing population extinction. Biologists at the University of Rochester, including Amanda Larracuente, professor of biology, and Daven Presgraves, University Dean’s Professor of Biology, are using population genomics for the first time to explain the evolution and consequences of known selfish genetic elements. as Segregation Distortion ( SD ). In a paper published in the journal eLife the researchers reported that SD has led to dramatic changes in chromosomal organization and genetic diversity. Sequencing the genome first Researchers use fruit flies as model organisms to study SD , a selfish genetic element that deviates from the rules of just genetic transmission. Fruit flies share about 70 percent of
