Quantifying heterogeneity in breast cancer

A new study by Fox Chase researchers finds that heterogeneity is prevalent even in early-stage ductal carcinoma in situ (DCIS) breast cancer, making it challenging for pathologists to accurately diagnose and treat the disease. The results suggest that a multiple-target approach may be necessary to effectively combat breast cancer.

Reliably higher levels of healthy compound in Beneforte broccoli

Beneforté broccoli consistently produces 2-3 times the amount of glucoraphanin as other varieties without affecting yield or nutrient levels. Genetic analysis identified a single gene responsible for increased glucoraphanin production, which channels more sulphur from the soil into this compound.

System provides clear brain scans of awake, unrestrained mice

Scientists use AwakeSPECT to study Alzheimer's, dementia, and Parkinson's disease by acquiring functional images of conscious mouse brains. The system, developed at Jefferson Lab, tracks movement and removes motion artifacts, providing detailed brain chemistry changes.

Genetic variants of heart disorder discovered in some cases of stillbirth

Researchers identified genetic variants associated with long QT syndrome in a small number of cases of intrauterine fetal death, including stillbirths. The study found that these variants were more common in late miscarriages and stillbirths than expected, suggesting a potential link between LQTS and intrauterine fetal deaths.

Dartmouth researchers find there is no single sexy chin

Dartmouth researchers found significant geographic differences in male and female chin shapes, contradicting the notion of a single 'sexy' chin. The study tested the universal facial attractiveness hypothesis across nine regions, challenging Darwin's theory on the evolution of physical characteristics.

Beavers use their noses to assess their foes

A study by Helga Tinnesand and her colleagues found that beavers use anal gland secretions to assess their foes, with older sons detected as a greater threat. This allows established territory owners to accurately gauge the level of response required.

Research suggests new approach for spinal muscular atrophy

A new study published in the Journal of Neuroscience reports that Riluzole, an ALS drug, has pinpointed a mechanism for spinal muscular atrophy (SMA) and restored neuromuscular function in worm models. The researchers suggest targeting SK2 potassium channels could lead to a more effective therapy for SMA patients.
