Maps developed with artificial intelligence confirm low levels of phosphorus in Amazonian soil

As the impacts of climate change increasingly affect the daily lives of residents in several countries, including Brazil, the resilience of forests, especially tropical ones such as the Amazon, has become a frequent topic of research. In addition to studying various factors that influence the way vegetation reacts to global warming, scientists are seeking to improve vegetation models—tools that...

Women should be included in decisions on the protection of human rights in the climate crisis, say researchers

Eighty percent of climatic migrants are women and children. This figure means that a new international legal framework is required to protect human rights by adding gender-sensitive measures to policies and legislation. This is the claim made by Susana Borràs, a researcher from the University of Rovira's Department of Public Law in an article published in the journal Environmental Policy and Law,...

Researchers discover new lantibiotic produced by staphylococci

Researchers at the University Hospital Bonn (UKB), the University of Bonn, and the German Center for Infection Research (DZIF) have discovered a new lantibiotic, namely epilancin A37. It is produced by staphylococci that colonize the skin and act specifically against their main competitor there, the corynebacteria.

Pump-probe high-harmonic spectroscopy could catch geometric phase effect around conical intersection in molecule: Study

A collaborative research team from Nanjing University of Science and Technology (NJUST) and East China Normal University (ECNU) has theoretically proposed that a pump-probe high-harmonic spectroscopy (HHS) driven by VUV-IR pulses can catch the geometric phase (GP) effect around the conical intersection (CI) and distinguish its quantitative behavior from the case of avoided crossing (AC). The...

Study reveals voter moral justifications for politicians' misstatements

In a new study, researchers have used online surveys conducted primarily when Donald Trump was president to show that both Republican and Democratic voters provided explicit moral justification for politicians' statements that were factually inaccurate, especially when they aligned with their personal politics.

'Sour Patch' adults: 1 in 8 grown-ups love extreme tartness, study shows

For most people, biting into a lemon would leave them puckered up and desperate to lose that sour flavor, but a new study by Penn State researchers revealed that roughly one in eight adults like intensely sour sensations. The cross-cultural study, recently published in the journal Food Quality and Preference, demonstrated there is a subset of "sour likers" who enjoy exceptionally sour foods.

Design strategies toward plasmon-enhanced 2D material photodetectors

Traditional semiconductors such as Si, GaAs, and HgCdTe seem unable to meet the development trend of electronic devices that feature ultra-small volume, lightweight, and low power consumption. These limitations of traditional semiconductors mainly stem from complex growth conditions and low-temperature working environments.

NASA scientists gear up for solar storms at Mars

In the months ahead, two of NASA's Mars spacecraft will have an unprecedented opportunity to study how solar flares—giant explosions on the sun's surface—could affect robots and future astronauts on the Red Planet.
