Phys.org / 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 ...
Phys.org / 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 ...
Phys.org / Novel chemical reaction expands options for building DNA-encoded libraries
Finding new drugs requires screening vast numbers of compounds to identify those that interact with a biological target. DNA-encoded libraries (DELs) help researchers explore these large collections by attaching a short DNA ...
Phys.org / Researchers create light-activated cages for 'protein killer' molecules
Researchers have created a molecular "cage" that keeps protein-degrading drug molecules inactive until they are exposed to low-energy red light. The technology, called RuPHOTACs, controls when and where these molecules become ...
Phys.org / Crowding can speed up enzyme reactions—until protein droplets become too packed
Our cells are a hotbed of activity, with reactions churning away to keep us alive. But the cytoplasm, where many metabolic reactions take place, is not uniform. Instead, proteins and other molecules cluster together into ...
Phys.org / Scientists find that a 10-millisecond flash could help build more sensitive gas sensors
Nitrogen dioxide is a harmful gas that requires sensitive detection. Researchers used intense light pulses lasting 10 milliseconds to make molybdenum disulfide flakes and anchor isolated metal atoms in one step. Adding platinum ...
Phys.org / WaterPuzzle uses magnets to model water's hydrogen bonds for hands-on classroom exploration
Water is one of the most essential components of life, and many of its unique properties arise from interactions between its molecules. Hydrogen bonds influence water's physical properties, contribute to the formation of ...
Phys.org / Ancient charcoal remains provide clues about Neanderthal camp organization
Usually, people associate archaeological studies with bones, pottery and primitive tools, but archaeologists often find other clues about how ancient people lived hidden throughout a site. A new study, published in the Journal ...
Phys.org / Cosmic microwave background offers evidence of gas flowing in galaxy clusters
The cosmic microwave background (CMB) is a faint glow in the universe dating back to roughly 380,000 years after the Big Bang, long before stars or galaxies emerged. Detecting this light and mapping its fluctuations provide ...
Phys.org / Ultrathin carbon ribbons conduct electricity like metals in first successful synthesis
As modern electronic devices shrink, so do the metal electrical wires inside them. However, they start to run into serious problems the smaller they get. Conventional wires generate excessive heat and suffer a massive spike ...
Phys.org / New catalyst builds proton highways to tackle a long-standing hurdle in green ammonia synthesis
Over a century ago, the Haber-Bosch process, a two-step reaction for the synthesis of ammonia (NH₃), an irreplaceable chemical for the fertilizer industry, prevented the world from going into a serious food crisis. Today, ...
Phys.org / Grand Theft Astro: Stars' criminal histories could reshape estimates of their internal magnetic fields
Magnetic fields exist in many stars, including the sun. Yet they remain too poorly understood to be reliably included in stellar evolution models, limiting their accuracy. Now, a new study by researchers at the Institute ...
