RNA could form building blocks for nanomachines

A research team from Purdue University has successfully created RNA-based nanoscale structures, which could be used as building blocks for microscopic machines. The researchers have developed methods to self-assemble RNA molecules into complex shapes, such as arrays that can form the scaffolding on which other components could be mounted.

Children with serious insect-sting allergies should get shots to avoid life-threatening reactions

Researchers found that children who received venom allergy shots had significantly fewer life-threatening reactions when restung, even years later. Dr. Rebecca Gruchalla recommends the shots for kids with severe allergic reactions to insect stings, which are responsible for at least 40 fatal stings per year.

Rutgers-Newark scientist: Mosquitoes may carry lethal parasite

A Rutgers-Newark scientist has found that mosquitoes may carry a lethal parasite called B. algerae, which can invade human muscle tissue and cause death. The parasite is typically found in the tissues of mosquitoes and can be transmitted to humans through mosquito bites.

T. rex owes its giant size to the ultimate teenage growth spurt

Scientists charted T. rex life history for the first time, revealing a giant size due to an extraordinary growth spurt from 14 to 18 years of age. This was followed by about 10 years of little or no growth as an adult. The study provides insight into T. rex evolution, biology, biomechanics and population dynamics.

Cluster spacecraft catch crashing waves in Earth's magnetic bubble

The Cluster mission has found a new way for charged particles from the solar wind to enter Earth's magnetosphere, using giant vortices called non-linear Kelvin-Helmholtz waves. These vortices can carry particles inside the magnetosphere, potentially explaining the presence of hot plasma stored in the tail of Earth's magnetic field.

For kids who may never outgrow bee sting allergies: Shots reduce risk

A study found that children who received venom immunotherapy for moderate to severe allergic reactions had a lower risk of future reactions, including those with no prior treatment. The therapy was shown to last for up to three and a half years, making it an effective long-term solution for managing bee sting allergies.

Leukemia stem cells identified by Stanford researchers

Researchers at Stanford Medicine have identified leukemia stem cells in chronic myelogenous leukemia, a breakthrough that could lead to new targeted therapies. The discovery reveals that normal adult cells can mutate into cancer stem cells, which are resistant to chemotherapy and require a specific protein called Wnt to self-renew.
