Hackers get bum rap for corporate America's digital delinquency

A recent study by Phil Howard and Kris Erickson found that 60% of breached-record incidents between 1980 and 2006 were caused by organizational mismanagement, such as missing or stolen hardware. The number of reported incidents more than tripled in 2005 and 2006 after California's pioneering Notice of Security Breach law took effect.

Smithsonian scientists report ancient chili pepper history

Smithsonian researchers discovered that chili peppers were cultivated and traded as early as 6,000 years ago across the Americas, contributing significantly to our understanding of ancient agricultural practices. The findings provide a new window into the past, allowing researchers to trace the history of chili peppers in the Americas.

How trees manage water in arid environments

In semi-arid environments, trees have evolved to access moisture from bedrock fractures and quickly recover when heavy rains occur. Understanding these surface-atmosphere interactions is crucial for predicting water supplies and managing scarce resources.

Health inequalities are a growing problem worldwide

A recent study by Yale University researchers highlights substantial global health inequalities influenced by economic, social, and health-sector variables. Countries with low income and high mortality rates have lower investment in human and physical resources, more health risks, and worse educational outcomes.

Health inequalities are a growing problem worldwide

The study reveals substantial global health inequalities influenced by geography, with countries like sub-Saharan Africa and Afghanistan facing higher child mortality rates. The authors found a four-fold difference in poverty levels and less investment in human resources between these countries and their low-mortality counterparts.

AGU Journal highlights -- Aug. 29, 2006

Climate scientists analyzed data to determine that global warming is increasing Atlantic hurricane intensity. Additionally, the water cycle is changing, with seasonal trends shifting into spring. The study also found a connection between atmospheric tides and weather in the tropics influencing the equatorial ionosphere.

Be warned

A recent study conducted by Dr. Scott Sheridan at Kent State University found that almost 90% of residents aware of heat warnings took no action to avoid health issues. The study suggests that heat warning systems may need to be revised to better target vulnerable populations.

Fabled equatorial icecaps to disappear

The Rwenzori Mountains, home to one of four remaining tropical ice fields outside the Andes, are experiencing substantial reduction in glacial cover due to increasing air temperature over the last four decades. Glaciers are receding tens of meters each year, with less than one square kilometer of glacier ice remaining.

Hazard mitigation can save money

A study found that hazard mitigation grants can save up to $14 billion over 10 years by reducing property damage and loss of life. The grants also help reduce tax revenue losses due to economic disruption caused by natural hazards.

Giant ape lived alongside humans

Researchers have confirmed that Gigantopithecus blackii, a gigantic ape weighing up to 1,200 pounds and measuring 10 feet tall, roamed the same region as early humans in southern China. The species is believed to have co-existed with humans during a time of major evolutionary change.

California's oak woodlands face a new threat: Climate change

Climate change is expected to shift the suitable ranges of blue oak and valley oak in California, with potential habitats shrinking by nearly half, posing a challenge for conservation planning. The study highlights the importance of regional climate models for accurately predicting species' responses to climate change.

Dartmouth professor warns of misuse of mapping technology in political redistricting

A Dartmouth professor warns that GIS technology can be used to manipulate election results, as state legislatures have incentives to use partisan information but few incentives to respect communities of interest. Nonpartisan redistricting commissions may offer a solution, but clear rules are needed to ensure fair representation.

Dartmouth researcher tracks how immigrants fit in by studying household configurations

A Dartmouth researcher studied immigrant households to find that generational status, not income, has the most effect on immigrant dispersion. The study challenges current ideas about where immigrants live and suggests that states with multi-generational households may have easier socio-cultural and economic adjustments.

Space matters: Estimating species diversity in the fossil record

Estimates for the number of living species on earth range from 3.5 million to over 30 million, but only 1.9 million have been classified and described. A new study uses the species-area effect to estimate historical biodiversity in the fossil record, finding a strong relationship between species richness and geographic area.
