New defense mechanism against viruses discovered

Researchers from ETH Zurich have discovered a new form of innate immune defence against certain RNA viruses, including those causing hepatitis C, yellow fever, and dengue fever. The NMD system, which is a quality control mechanism in cells, also serves as a general virus restriction mechanism in plants.

Not all phytoplankton in the ocean need to take their vitamins

Researchers discovered that E. huxleyi can grow without thiamine and prefers precursor chemical HMP instead, re-evaluating the importance of vitamin B1 in regulating algal communities. This finding has implications for understanding climate change's impact on marine ecosystems and predicting global carbon cycles.

Georgia Tech jailbreaks iOS 7.1.2

Researchers at Georgia Tech have discovered a way to jailbreak current generation iOS devices running iOS 7.1.2, showcasing the vulnerability of Apple's closed platform to exploitation. The study highlights the importance of patching all publicly disclosed threats to prevent potential attacks.

New network unites university health care research

Four major health institutions have partnered to create a Clinical Data Research Network, leveraging PCORI's $7 million funding. The network will study patient outcomes for obesity, atrial fibrillation and idiopathic pulmonary fibrosis, expanding research capabilities and collaboration opportunities.

Decoding dengue

Scientists discovered a new pathway the dengue virus takes to suppress the human immune system, deepening understanding of the virus and its potential for more effective treatments. The study reveals how sfRNA interacts with proteins in the cell to evade antiviral defenses.

Soldiers who kill in combat less likely to abuse alcohol

Researchers found that killing experiences may cause soldiers to become more aware of their own mortality, triggering a focus on self-preservation and reduced high-risk alcohol consumption. The study suggests that this increased sense of vulnerability leads to decreased alcohol abuse rates among soldiers who have killed in combat.

New research on gigabit wireless communications

The study proposes enhanced technologies and algorithms to increase data capacity and densification in short-range wireless networks, achieving speeds of up to 7Gbps per link. Beamforming is also explored as a solution for multi-gigabit connections between base stations and users, with an adaptive algorithm reducing interference.

Research shows link between states' personalities and their politics

A recent study found a strong correlation between states' core political characteristics and collective personality traits. States with lower conscientiousness or higher agreeableness tend to have a positive view of government, while those with higher openness to experience are more likely to be ideologically liberal.
