The sweet smell of strawberries and other fruits is thanks to a chemical compound called ester, which is also found in many fats and polyesters. The ubiquitous compound can be broken down to produce desirable alcohols and other chemicals for use across industries including pharmaceuticals and cosmetics, but the process can be costly, both financially and in terms of the environment.

In August 2021, an earthquake struck southwest Haiti, killing thousands of people and leaving more than half a million seeking help. Assessment of this disaster and its response can serve as a model for evaluating future disasters and making life-saving improvements, according to new research from a University of Notre Dame professor.

BIRMINGHAM, Ala. – Memory immune cells reside in many tissues, poised to react to a second infection or continuing antigen. Yet little is known about these tissue-resident memory cells — how they get there, how they evolve and how they compete in tissues.

Researchers have consistently shown that prenatal exposure to Di (2-ethyhexyl) phthalate harms the reproductive system in male mice and causes fertility defects. In a new study, scientists from the University of Illinois Urbana-Champaign have shown that the combination of DEHP and a high-fat diet in pregnant mice can cause more damage to pups than each factor alone.  Credit: Fred Zwicky Researchers have consistently shown that prenatal exposure to Di (2-ethyhexyl) phthalate harms the reproductive system in male mice and causes fertility defects.

KEY TAKEAWAYS Credit: Tanmoy Saha, Brigham and Women’s Hospital KEY TAKEAWAYS Lung cancer is the most diagnosed cancer and the leading cause of cancer death globally, representing an urgent need for new and improved treatment options. Researchers from Brigham and Women’s Hospital developed a new nanomedicine therapy that delivers anticancer drugs to lung cancer cells and enhances the immune system’s ability to fight cancer. The research must undergo rigorous toxicology studies before moving into clinical testing in patients but represents a potential treatment for patients who have failed t ..read more

A liquid crystal source of photon pairs

2d ago
Spontaneous parametric down-conversion (SPDC), as a source of entangled photons, is of great interest for quantum physics and quantum technology, but so far it could be only implemented in solids. Researchers at the Max Planck Institute for the Science of Light (MPL) and Jozef Stefan Institute in Ljubljana, Slovenia, have demonstrated, for the first time, SPDC in a liquid crystal. The results, recently published in Nature, open a path to a new generation of quantum sources: efficient and electric-field tunable.
