When seconds count: Interventional radiology treatment for pulmonary embolism saves lives

A recent study published in the Journal of Vascular and Interventional Radiology found that catheter-directed therapy is a relatively safe and effective treatment for acute massive pulmonary embolism. The treatment was lifesaving in 86.5% of cases studied and had only a 2.4% chance of major complications.

A bubbling ball of gas

The SUNRISE balloon-borne telescope has delivered images showing the complex interplay on the solar surface with unprecedented detail. The mission reveals a connection between magnetic field strength and solar brightness, with implications for Earth's heat input.

Faulty body clock may make kids bipolar

Research found four alterations in RORB gene associated with pediatric bipolar disorder, linking circadian rhythm abnormalities to the condition. The study suggests that clock genes may be important candidates for further investigation into bipolar disorder's molecular basis.

Why can't chimps speak?

A UCLA/Emory study discovered significant differences between the human and chimp versions of the FOXP2 gene, which may explain why humans developed language while chimps did not. The research provides insight into the evolution of the human brain and may lead to new drug targets for disorders characterized by speech disruption.

Exoplanets clue to sun's curious chemistry

Astronomers have discovered that Sun-like stars with planetary systems tend to have lower levels of lithium than those without planets. The study, which analyzed 500 stars, found that planet-bearing stars had less than 1% of the lithium present in other similar stars.

New brain findings on dyslexic children

Research from Northwestern University's Auditory Neuroscience Laboratory confirms that children with developmental dyslexia have trouble tuning into relevant auditory signals. The study suggests that poor readers who struggle with processing sound in noisy environments may benefit from simple strategies to enhance their listening skills.

A motley collection of boneworms

Researchers have discovered up to 15 species of boneworms in Monterey Bay, which feed on dead whales and exhibit unique life cycles. The worms' ability to adapt to different environments and find food sources has led scientists to estimate their evolutionary origins, suggesting they may date back to the time of dinosaurs.

Scientists decipher the formation of lasting memories

Researchers at Karolinska Institutet have discovered a mechanism that controls the brain's ability to create lasting memories. The study found that signalling via the nogo receptor 1 plays a key part in this process, enabling the conversion of short-term memories into long-term ones.

Erythropoiesis-stimulating agents associated with higher risk of venous thromboembolism

A study published in the Journal of the National Cancer Institute found that erythropoiesis-stimulating agents increase the risk of venous thromboembolism in cancer patients. The use of these agents, approved to reduce blood transfusions during chemotherapy, may outweigh benefits due to associated risks.
