Leading scholarly database listed hundreds of papers from ‘hijacked’ journals
Polar bears are tough animals to track. Scientists must brave frigid Arctic landscapes to observe them, if they can spot them at all. And if they want to collect genetic information, they often have to dart and capture the animals—a risky proposition for both researcher and bear. A new approach may lend a paw to such efforts.
In two new studies, scientists report that they can...
Exploring the limitations of asteroid crater lakes as climate archives
Scopus, a widely used database of scientific papers operated by publishing giant Elsevier, plays an important role as an arbiter of scholarly legitimacy, with many institutions around the world expecting their researchers to publish in journals indexed on the platform. But users beware, a new study warns. As of September, the database listed 67 “hijacked” journals—legitimate...
Review of education highlights network ethnography in researching global education policy
In southern Germany just north of the Danube, there lies a large circular depression between the hilly surroundings: the Nördlinger Ries. Almost 15 million years ago, an asteroid struck this spot. Today, the impact crater is one of the most useful analogs for asteroid craters on early Mars.
Limitations of asteroid crater lakes as climate archives
The word "mobility" conjures up images and ideas of the movement of people, capital, and things from one place to another. The globalized world of the 21st century has ushered in an era of "new mobility" studies fronted by sociology researchers and human geography scholars. It encompasses not only the diverse movements of people, including tourists and corporate elites, and the associated...

Plant nurseries are exacerbating the climate-driven spread of 80% of invasive species
In southern Germany just north of the Danube, there lies a large circular depression between the hilly surroundings: the Nördlinger Ries. Almost 15 million years ago, an asteroid struck this spot. Today, the impact crater is one of the most useful analogues for asteroid craters on early Mars. Studying the deposits of the former lake that formed in the crater is particularly informative. These...

Bacteria's mucus maneuvers: Study reveals how snot facilitates infection
Researchers have provided detailed maps of how 144 common invasive plants species will react to 2° Celsius of climate change in the eastern U.S., as well as the role that garden centers currently play in seeding future invasions.

Newly identified biomarkers may detect early cognitive decline via blood test
Sniffles, snorts and blows of runny noses are the hallmarks of cold and flu season -- and that increase in mucus is exactly what bacteria use to mount a coordinated attack on the immune system, according to a new study. The team found that the thicker the mucus, the better the bacteria are able to swarm. The findings could have implications for treatments that reduce the ability of bacteria to...

Addicted to your phone? New tool identifies overuse of digital media
For some people, extreme stressors like psychiatric disorders or childhood neglect and abuse can lead to a range of health problems later in life, including depression, anxiety and cardiovascular disease. A new study identified genetic indicators that can predict another health problem, the decline of cognitive abilities, among people who have been affected by these extreme stressors.

Depression, constipation, and urinary tract infections may precede MS diagnosis
A new tool will make it easier for clinicians and researchers to measure digital media addiction as new technologies emerge.

Satellite observations reveal latitudinal variability and asymmetry in local temperature responses to land cover changes
In some diseases, the underlying processes can start years before a diagnosis is made. A new study finds that people who later develop multiple sclerosis (MS) are more likely to have conditions like depression, constipation and urinary tract infections five years before their MS diagnosis than people who do not develop MS. The study also found that sexual problems and bladder infections, or...
Examining advances in additive manufacturing of promising heterostructures and their biomedical applications
Land cover changes (LCCs) affect surface temperatures at local scale through biophysical processes. However, limited by the coarse spatial resolution of available data, past observation-based studies mainly focused on the potential effects of virtual afforestation/deforestation using the space-for-time assumption. Prof. Li and his team first generated a high-resolution temperature dataset and then...
A theoretical framework for integrating diversity and organizational embeddedness
To the authors' knowledge, there have been no review papers that summarize the biomedical applications of heterostructures prepared by additive manufacturing. This paper aims to highlight the research progress in additive manufacturing of promising heterostructure for bioimplants.
Digital marketplace: The role of probabilistic selling strategies in the travel industry
To create diverse, equitable, and inclusive workplaces, retaining and motivating valued employees from all social groups is the key. However, for managers and leaders, that is quite challenging.
Scientists develop a new high-efficiency mercury removal photocatalyst
In today's digital age, the travel industry is undergoing a significant transformation, with online platforms becoming central hubs for a variety of travel services. These platforms allow travelers to search, compare, and make purchases, moving beyond traditional offline methods.
Novel mineral piezocatalysts offer innovative approaches for soil remediation
Scientists from Shanghai University of Electric Power of College of Energy and Mechanical Engineering have developed a new high-efficiency mercury removal photocatalyst.
Scandinavia's oldest known ship burial is located in mid-Norway
Polycyclic aromatic hydrocarbons (PAHs) removal in the soil environment is of great significance for repairing the long-term damaged ecosystem. However, the poor mass transfer process and low catalytic activity in most conventional methods lead to limited removal efficiency.
Forecasting forest health using models to predict tree canopy height
This summer, archaeologists and a metal detectorist conducted a small survey of Herlaugshagen, at Leka in the northern part of Trøndelag County. They found something amazing.
Opinion: COP28 president is wrong—science clearly shows fossil fuels must go (and fast)
Tree height is an important indicator of a forest's maturity and overall health. Forest restoration projects rely on tree height as a predictor and measurement of success, but forecasting a forest's future tree height based on observations alone is almost impossible. Too many factors contribute to the growth and health of trees.
The silver bullet that wasn't: Glyphosate's declining weed control over 25 years
According to the president of COP28, the latest round of UN climate negotiations in the United Arab Emirates, there is "no science" indicating that phasing out fossil fuels is necessary to restrict global heating to 1.5°C.
Picking up good vibrations: The surprising physics of the didgeridoo
It has been a quarter century since corn and soybeans were engineered to withstand the withering mists of the herbicide glyphosate. Initially heralded as a "silver bullet" for weed control, the modified crops and their herbicide companion were quickly and widely adopted across corn and soybean-growing regions of North America. In the following years, though, weeds targeted for eradication quietly...
AI tool could increase the number of people exiting homelessness, reduce racial bias in services: Report
Australia's most iconic sound is almost certainly the didgeridoo. The long wooden tube-shaped instrument is famous for its unique droning music and has played a significant role in Australian Aboriginal culture for thousands of years. Despite the instrument's simple design, the playing technique can be highly complex.
USC researchers have developed an artificial intelligence tool they recommend as one of several measures that would help homeless service agencies control for potential biases and ensure that applicants have a fair chance at getting housing.
