Scientists synthesize isotopic atropisomers based on carbon isotope discrimination
In chemistry, a molecule or ion is said to be chiral if it cannot be superposed on to its mirror image by any combination of rotations, translations, or conformational changes. A chiral molecule or ion exists in two forms, called enantiomers, that ar.....»»

Squishy microgels in granular biomaterials confine and direct cell behavior
A simple biomaterial-based strategy that can influence the behavior of cells could pave the way for more effective medical treatments such as wound healing, cancer therapy and even organ regeneration, according to a research team at Penn State......»»
Socioeconomic status explains most of the racial and ethnic achievement gaps in elementary school
For decades, white students have performed significantly better than Black and Hispanic students on tests of academic achievement. Explanations for these achievement gaps include poverty and systems that result in discrimination. Others cite struggle.....»»
Is South Africa one of the most politically polarized countries in the world? No, it"s not, says sociologist
A number of reports have called South Africa a politically polarized society. This may seem uncontroversial, given the country's history of dispossession and discrimination during colonialism and apartheid, and their continuing legacy after 30 years.....»»
Firefly Aerospace rakes in more cash as competitors struggle for footing

Bioluminescent proteins made from scratch enable non-invasive, multi-functional biological imaging
Bioluminescence is the natural chemical process of light creation in some living creatures that makes fireflies flicker and some jellyfish glow. Scientists have long been interested in borrowing the secrets of these animals' light-producing genes to.....»»
Low-cost method removes micro- and nanoplastics from water
Researchers at the University of São Paulo (USP) in Brazil have developed a novel nanotechnology-based solution for the removal of micro- and nanoplastics from water. Their research is published in the journal Micron......»»
Nations to submit boosted climate plans: what"s at stake?
Nations have begun setting carbon-cutting targets for the decade ahead, and how ambitious these pledges are could make or break global efforts to avoid dangerous levels of climate change......»»
Self-organization of living matter into complex structures: How light pattern impacts aggregation of active filaments
When active filaments are exposed to localized illumination, they accumulate into stable structures along the boundaries of the illuminated area. Based on this fact, researchers at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS).....»»
Will we be able to continue living by the sea? Ocean experts explore considerations for governments
A publication recently launched by leading European Ocean scientists, titled Navigating the Future VI (NFVI), calls attention to the fact that we do not yet sufficiently consider how climate-induced changes in the ocean will impact how we live alongs.....»»
A failed experiment and chance open up new paths to an established reaction for chemists
The original plan of the research groups of Dr. habil. Christian Hering-Junghans and Prof. Torsten Beweries at the Rostock LIKAT was to develop a phosphorus-based ligand. However, the syntheses led to a different substance than expected, namely a tri.....»»
Using CRISPR to decipher whether gene variants lead to cancer
In recent years, scientists have created a range of new methods based on CRISPR-Cas technology for precisely editing the genetic material of living organisms. One application is in cell therapy: A patient's immune cells can be specifically reprogramm.....»»
