UC Davis researchers discover complexities of DNA repair

Researchers found that recombination, a key DNA repair process, has a self-correcting mechanism allowing DNA to make a virtual u-turn and start over. This discovery contributes new understanding to basic cancer biology and may improve the efficacy of cancer treatments.

How plants sense low oxygen levels to survive flooding

Researchers at UC Riverside and the University of Nottingham have discovered how plants sense low oxygen levels to survive flooding. They found that key plant proteins become unstable when oxygen is normal but stable when oxygen levels drop, allowing plants to tap into their energy reserves and survive in low-oxygen conditions.

Female shift workers may be at higher risk of heart disease

A study by Dr. Joan Tranmer found that female hospital staff working night shifts are at a higher risk of developing metabolic syndrome, high blood pressure, and abdominal obesity. The study suggests that age and shift work status are significantly associated with increased risk.

Will my breast cancer spread? Discovery may predict probability of metastasis

Researchers at Huntsman Cancer Institute have discovered a new way to model human breast cancer that could lead to predicting which breast cancers will spread. The model was created using tumor tissue grafted into mouse mammary glands and found that it accurately predicted the behavior of human breast cancers.

Production of biofuel from forests will increase greenhouse emissions

A comprehensive study found that biofuels produced from West Coast forests would release more carbon dioxide into the atmosphere than current forest management practices. The study examined various forest types and management approaches, concluding that even optimal efficiency levels would increase emissions by up to 14%.

Cooperative communications when collaborators are not synchronized

Cooperative communications technology allows multiple single-antenna terminals to share their antennas, creating a virtual antenna array. This enables the exploitation of spatial resource in traditional MIMO techniques without requiring multiple antennas. Distributed space-time coding (DSTC) has emerged as an efficient technique for pr...

Sleeping sickness drug may provide long-term protection against skin cancer

Researchers found that an antiparasitic agent used to treat African sleeping sickness may provide long-term protection against nonmelanoma skin cancers. The study, conducted on 209 participants, showed a reduced incidence of skin cancers among those who took the drug for five years compared to those who received a placebo.

Survey finds public support for geoengineering research

A new survey reveals that 72% of respondents approve research into climate-manipulating technique, with broad public awareness and surprisingly diverse political views. The study suggests that dialogue surrounding SRM needs to be broadened to include ideas of risk, values, and trade-offs.

Smaller 2 cm excision margin for melanomas thicker than 2 mm results in similar levels of recurrence and death as larger 4 cm margin

A new study published in The Lancet suggests that a 2cm excision margin for skin melanomas thicker than 2mm is safe and effective, with similar levels of recurrence and death compared to a larger 4cm margin. This finding challenges current recommendations and may lead to changes in treatment guidelines.

Body weight, diet may be risk factors for non-Hodgkin lymphoma

Research found associations between obesity and increased risk of non-Hodgkin lymphoma in young adults. Diets high in trans fats and low in vegetables were also linked to a higher risk, while those with high vegetable intake had a lower risk. Obesity was particularly strong in men, who had a 64% higher risk of developing NHL.
