Scientists unravel the genetic coding of the pea

Researchers have created a genetic reference collection of mutant Pisum sativum plants, enabling the investigation of essential genes using TILLING (Targeting Induced Local Lesions IN Genomes) technique. This new tool has major benefits for crop breeders worldwide, providing an alternative to Agrobacterium-based techniques.

LA BioMed study finds hormone therapy increases frequency of abnormal mammograms, breast biopsies

A recent study published in Archives of Internal Medicine found that combined hormone therapy significantly increases the risk of abnormal mammograms and breast biopsies, compromising their diagnostic performance. The research involved 16,608 post-menopausal women and revealed a four percent greater risk of mammogram abnormalities afte...

Rats on islands disrupt ecosystems from land to sea, researchers find

A new study by UC Santa Cruz researchers found that rats on islands in the Aleutian Archipelago dramatically alter the intertidal zone, reducing seaweed and increasing snails, barnacles, and other invertebrates. The presence of rats also leads to a trophic cascade, resulting in reduced seabird populations and altered marine ecosystems.

Study examines long-term outcomes following blood clots

A study examining long-term outcomes following blood clots found that patients with pulmonary embolism are at higher risk of experiencing recurrent clotting, major bleeding episodes, or death. The research also highlights the need for better anticoagulation strategies to reduce complications in the community setting.

Who benefits from antidepressants? US health inequities

A new study published in PLoS Medicine suggests that antidepressants only provide clinically significant benefits for a small group of severely depressed patients. However, even among these patients, the improvement is not very great, and depressed people can still improve without chemical treatments.

STOP terrorism software

Researchers at University of Maryland's Institute for Advanced Computer Studies create SOMA Terror Organization Portal (STOP) to analyze and forecast terrorist organization behavior. The technology allows analysts to query learned rules, network with other experts, and test theories using data-driven forecasting capabilities.

10-year trends in heart failure

A new study from Duke University Medical Center found that heart failure incidence declined among the very elderly, while overall cases rose due to an aging population. The study examined Medicare beneficiaries' claims between 1994 and 2003 and found a decline in heart failure rates among those aged 80-84 years old.

Krill discovered living in the Antarctic abyss

Scientists have discovered Antarctic krill thriving in deep waters, down to 3000 meters, contrary to earlier assumptions about their surface-dwelling nature. This finding sheds light on the complex behavior of marine organisms and highlights the importance of exploring the deep sea to understand our planet.

Many stroke, heart attack patients may not benefit from aspirin

Researchers at the University at Buffalo found that up to 20% of patients taking aspirin for stroke and heart attack prevention do not respond to the medication, leading to increased risk of clinical failure. The study also identified factors associated with aspirin resistance, including younger age and underlying vascular disease.

First malaria map in 40 years shows extent of disease burden

A new global malaria map highlights the 2.37 billion people at risk from Plasmodium falciparum, with almost one billion in areas where the risk of infection is extremely low. The map aims to help researchers and funding agencies allocate resources more effectively by understanding the relative risk affecting different regions.
