The Crosses
This poem is dedicated to all the men and women, regardless of faith, who made the ultimate sacrifice for this nation. I have stood before the crosses as we laid a soldier down. They cast a simple shadow upon the upturned ground. The bugler sounds taps as each cross its witness bears to the journey of a soldier released from earthly cares. I have stood before the crosses and prayed a lonely praye

The price is right: Modeling economic growth in a zero-emission society
With increasing public awareness of crises associated with degraded environments and mounting pressure to act, governments worldwide have begun to examine environmentally sustainable policies. However, there are many questions about whether enacting these policies will negatively affect economic growth. Now, a model suggests that sustained GDP growth is possible even after spending to clean up pol

Scientists discover a new genetic form of ALS in children
In a study of 11 medical-mystery patients, an international team of researchers has discovered a new and unique form of amyotrophic lateral sclerosis (ALS). Unlike most cases of ALS, the disease began attacking these patients during childhood, worsened more slowly than usual, and was linked to a gene, called SPTLC1, that is part of the body's fat production system.

Måltiden viktig för barn med gastrostomi
Det kan vara komplicerat att få till en fungerande middag med barn. Och hur är det för familjer där vissa barn har en gastrostomi, och får föda via en "knapp" på magen i stället för munnen?

Isolating an elusive missing link
The water oxidation reaction (WOR) is one of the most important reactions on the planet since it is the source of nearly all the atmosphere's oxygen. Understanding its intricacies can hold the key to improve the efficiency of the reaction.

Phonon catalysis could lead to a new field
Batteries and fuel cells often rely on a process known as ion diffusion to function. In ion diffusion, ionized atoms move through solid materials, similar to the process of water being absorbed by rice when cooked. Just like cooking rice, ion diffusion is incredibly temperature-dependent and requires high temperatures to happen fast.
