Customizable nanoparticles show potential for delivering personalized cancer vaccines
A nanoscale particle with a unique structure, developed at MIT, holds potential as a customizable delivery vehicle for personalized cancer vaccines. The backbone of the vaccine is a modified, harmless bacteriophage called M13, which forms a nanofiber that can be coated with cancer antigens. By precisely controlling the density of those cancer proteins, the researchers found that they could create a vaccine that prevents the development of colon tumors in mice.

Snowfall and clouds may slow East Antarctic ice loss in a warmer world
A new modeling study, published in the journal Nature Climate Change, suggests that the East Antarctic Ice Sheet may be more resilient to extreme long-term warming than previously estimated. Increased snowfall, greater cloud cover and changes in atmospheric circulation could partially offset ice loss—even under very high carbon dioxide concentrations.

NASA's Voyager 1 conserves power, resolves brief communications pause
NASA's Voyager team is celebrating two recent developments with the Voyager 1 spacecraft: In September, they successfully completed a months-long effort to stretch the spacecraft's diminishing power supply. Then, on Oct. 20, an unexpected loss of communication with the spacecraft resolved itself after 48 hours, before the team sent commands to the spacecraft to troubleshoot the issue.

The genetic cost of being a lazy parent ... if you're a cuckoo finch
African cuckoo finches (Anomalospiza imberbis) are very deceptive birds, or at least the mothers are. They sneak into the nests of other birds, such as prinias and cisticolas, to lay their eggs, then slip away and leave the hosts to raise the chicks.

Marine fossils in Colombia reveal possible evolutionary transition without mass extinction
A remarkably diverse fossil ecosystem in central Colombia that preserves an unusual overlap between survivors of older Jurassic groups and newer Cretaceous lineages has led researchers at McGill University and the Centro de Investigaciones Paleontológicas (CIP) to recognize a new pattern of large-scale evolutionary transition, one that does not include mass extinctions.

Award-winning research helps companies keep products where they're needed most
Before a stick of deodorant reaches a consumer's bathroom counter, it moves through a complex supply chain. Raw materials and packaging components are sourced, assembled into a finished product and shipped through warehouses and distribution centers before finally reaching a store shelf.

JWST reveals a distant galaxy that may let most of its ionizing radiation escape
Astronomers using the James Webb Space Telescope (JWST) have found evidence that a distant, exceptionally blue galaxy may allow most of its ionizing radiation to escape into space. Known as EBG-1, the gravitationally lensed galaxy is seen at a redshift of 9.244, about 530 million years after the Big Bang. The paper was posted to the arXiv preprint server on Oct. 16.

NASA's TRACERS first results offer peek into violent magnetic process
NASA's TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission has gathered its first clues to how space weather affects Earth's magnetic field. In a new paper published in the Journal of Geophysical Research: Space Physics, researchers break down how these interactions work after analyzing initial observations from the first year of the mission.
