Pathologists identify patterns of mutations to help inform design of future trials

A study published by the International Association for the Study of Lung Cancer found that 54% of patients with early stage node-negative lung adenocarcinoma had tumors with at least one biologically relevant mutation. The researchers also discovered mutations associated with drug resistance in these patients.

Did evolution give us inflammatory disease?

Researchers found 21 genomic regions with a 'signature' for both inflammatory disease susceptibility and natural selection. These variants rose in frequency to help protect humans against viruses and bacteria, but now increase the risk of autoimmune diseases like multiple sclerosis and rheumatoid arthritis.

When a gene is worth 2

A study led by Paula Duque discovered a gene ZIFL1 that encodes two proteins with different biological roles in plants. The researchers found that the gene's two proteins are involved in hormone transport and drought tolerance, challenging the long-held notion that each gene can only codify for one protein.

Alley receives AAAS Public Engagement Award

Richard B. Alley, a renowned geoscientist, has been awarded the AAAS Public Engagement in Science Award for his outstanding contributions to popularizing climate science. His work has helped demonstrate that past regional to global climate changes occurred rapidly and significantly impacted the environment.

It all hinges on the bottom line

A new study by Concordia University researchers found that companies with financial restatements are more likely to have poor corporate governance, including high growth rates and less independent oversight. These firms are also more likely to replace top executives and auditors in an attempt to improve their public image.

Removing orbital debris with less risk

The study compares in-orbit debris removal options, considering their potential risk of creating new debris or disabling working satellites. Inflatable drag enhancement devices are found to have the lowest risk, while electromagnetic tethers pose a high risk for disabling operational satellites.

Genetic analysis saves major apple-producing region of Washington state

Researchers at the University of Notre Dame used genetic analysis to identify a harmless fruit fly in Washington state, preventing costly quarantine measures. The study's findings demonstrate the potential for rapid and accurate identification of insect species, which could have significant implications for agriculture and public health.
