New research finds one copy of a protective genetic variant, APOE3 Christchurch, delayed onset of Alzheimer's disease for 27 members of a ~6,000-person family in Colombia at high risk for early-onset Alzheimer's in their 40s due to carrying the 'Paisa' (Presenilin-1 E280A) mutation. This work builds on a 2019 case report of a woman in this family who had two copies of the Christchurch variant and delayed Alzheimer's into her 70s. The new findings are the first to show that one copy of the variant confers some level of protection and increases the researchers' confidence that this genetic pathway should be targeted for therapeutics.

Researchers have developed a non-chemotherapy treatment regimen that is achieving full remissions for some people with aggressive B-cell lymphoma that has come back or is no longer responding to standard treatments. The five-drug combination targets multiple molecular pathways that diffuse large B-cell lymphoma (DLBCL) tumors use to survive.

Viruses, including the coronavirus that causes COVID-19, can get passed from person to person via contaminated surfaces. But can some surfaces reduce the risk of this type of transmission without the help of household disinfectants? Wood has natural antiviral properties that can reduce the time viruses persist on its surface -- and some species of wood are more effective than others at reducing infectivity.
