Study suggests best order of treatment for brain metastases in EGFR lung cancer

A study of 351 patients with EGFR mutant lung cancer and brain metastases found that radiation therapy followed by targeted medicines resulted in the longest overall survival, with median survival times of 46 months and 30 months respectively. The findings suggest that a more aggressive approach to treating brain metastases may be the ...

Jumping spiders court in color

Two groups of jumping spiders, Habronattus and Maratus, have evolved rare color vision to see reds, yellows and oranges. They use different mechanisms, with Habronattus employing a red filter and Maratus relying on ultraviolet, blue and green sensitive cells.

Rhino genome results

The San Diego Zoo's Frozen Zoo cell cultures contain genetic variation missing in surviving individuals of the critically endangered northern white rhinoceros. Genome-wide levels of genetic diversity and inbreeding in both southern and northern white rhinos were examined to aid future efforts toward genetic rescue and assisted reproduc...

Fixating on faces

Researchers found two types of face cells that respond differently to human and non-human faces. The study's findings suggest that the brain processes faces based on attention focus, not just visual presence. This discovery may lead to a better understanding of social cognitive defects like autism.

Antibody combination puts HIV on the ropes

A study using antibodies from an elite controller has shown that a combination of three broadly neutralizing antibodies can completely suppress HIV in infected mice. The finding validates the approach of using multiple antibodies to control HIV infection, pointing towards a potential new treatment for people infected with HIV.

Triggering the brain's auto-focus

Duke University researchers identified the caudate nucleus as the brain structure responsible for forming direct links between environmental stimuli and enhanced focus. By repeating exposure to specific faces, participants could trigger automatic focus and bypass distractions.

Floating towards water treatment

Researchers engineered four floating treatment wetland designs using different materials and plants, finding they can affect water quality in similar ways to natural wetlands. The study suggests these systems could help treat wastewater by enhancing nitrogen removal and managing algal blooms.
