See How Scientists Put Together the Complete Human Genome

For the first time, researchers have sequenced all 3,117,275,501 bases of our genetic code Credit: Martin KrzywinskiAdvertisement The human genome is at last complete. Researchers have been working for decades toward this goal, and the Human Genome Project claimed victory in 2001, when it had read almost all of a person’s DNA. But the stubborn… Continue reading See How Scientists Put Together the Complete Human Genome

Building a Professional Early Childhood Workforce Requires a ‘Compensation-First’ Approach

Teachers who work in childcare settings in the United States earn $11.65 per hour on average—less than half of what their peers working in schools earn, and below a living wage in most U.S. counties. Accordingly, even prior to the pandemic, childcare teachers (PDF) left the profession at considerably higher rates than K–12 teachers. In… Continue reading Building a Professional Early Childhood Workforce Requires a ‘Compensation-First’ Approach

AI Diagnoses Devastating Olive Tree Infection

An aggressive plant pathogen that wipes out olive trees is projected to cost Italy billions of euros over the next 50 years. Xylella fastidiosa—a bacterium named for its pickiness when grown in the laboratory—was detected in southern Italy in 2013. It is now designated a “quarantine organism” in the European Union: infected trees, some hundreds… Continue reading AI Diagnoses Devastating Olive Tree Infection

Truth Decay and National Security, Gun Violence, Blockading Crimea: RAND Weekly Recap

This week, we discuss how Truth Decay affects national security; America’s gun violence problem; why blockading Crimea may be Ukraine’s best option; improving educational outcomes for kids in foster care; the benefits of investing in women’s health research; and why the Army should be looking for slightly older recruits.

Cheap New Method Breaks Down ‘Forever Chemicals’

Researchers have developed an approach to break down a class of long-lasting chemicals that they say is easier and cheaper than the harsh methods currently used. The work also hints at how these chemicals, which have been linked to health problems, fall apart — a finding that could help to ultimately destroy these persistent pollutants. Per-… Continue reading Cheap New Method Breaks Down ‘Forever Chemicals’

Why China Should Worry About Asia’s Reaction to AUKUS

When U.S. President Joe Biden met with Australian Prime Minister Anthony Albanese and British Prime Minister Rishi Sunak in San Diego last month, the three leaders announced a crucial next step for the Australia–United Kingdom–United States (AUKUS) security pact. Australia will purchase at least three, and possibly five, Virginia-class nuclear-powered submarines from the United States… Continue reading Why China Should Worry About Asia’s Reaction to AUKUS

How the Inside of a Black Hole Is Secretly on the Outside

Theoretical physics has been in crisis mode ever since 1974, when Stephen Hawking argued that black holes destroy information. Hawking showed that a black hole can evaporate, gradually transforming itself and anything it consumes into a featureless cloud of radiation. During the process, information about what fell into the black hole is apparently lost, violating… Continue reading How the Inside of a Black Hole Is Secretly on the Outside
