A vector refers to an organism that carries and transmits an infectious disease, as mosquitoes do malaria.
Lead compounds are chemical compounds that show promise as treatment for a disease and may lead to the development of a new drug.
Antiplasmodial lead compounds are those that counter parasites of the genus Plasmodium, which is the parasite that infects mosquitoes and causes malaria in people.
The study findings were published in Nature Communications on 11 January 2021, at a time when malaria incidence generally peaks after the holiday season.
Recently, the innovation project watermelon and melon cultivation and physiology team of Zhengzhou Fruit Research Institute has made new progress in the metabolism regulation of sugar and organic acid in watermelon fruit. The changes of sugar and organic acid during the fruit development were analyzed and the key gene networks controlling the metabolism of sugar and organic acid during the fruit development were identified.
If you asked people which group of animals is the most abundant on earth, hardly anyone would know the right answer. Ants? Fish? No, and not humans either. The answer is nematodes, also known as roundworms. Four out of five animals on earth belong to this group, and the reason hardly anyone is aware of the fact is that they live underground, invisible to us. Together with thousands of other soil organisms, they quietly, discreetly and constantly perform enormously important services for the world above them.
Roughly 8,200 years ago, the island of Yuzhniy Oleniy Ostrov in Lake Onega in the Republic of Karelia, Russia, housed a large burial ground where men, women and children of varying ages were buried. Many of the graves contain an abundance of objects and red ochre, signifying the wish to ensure the comfort of the buried also after death. Pendants made of elk incisors were apparently attached to clothing and accessories, such as dresses, coats, cloaks, headdresses and belts.
When three galaxies collide, what happens to the huge black holes at the centers of each? A new study using NASA's Chandra X-ray Observatory and several other telescopes reveals new information about how many black holes are furiously growing after these galactic smash ups.
Astronomers want to learn more about galactic collisions because the subsequent mergers are a key way that galaxies and the giant black holes in their cores grow over cosmic time.
Scientists at the Walter Reed Army Institute for Research have shown that microRNA biomarkers related to Alzheimer's disease play a role in brain damage caused by traumatic brain injury.
Astronomers have curated the most complete list of nearby brown dwarfs to date thanks to discoveries made by thousands of volunteers participating in the Backyard Worlds citizen science project. The list and 3D map of 525 brown dwarfs -- including 38 reported for the first time -- incorporate observations from a host of astronomical instruments including several NOIRLab facilities. The results confirm that the Sun's neighborhood appears surprisingly diverse relative to other parts of the Milky Way Galaxy.
NEW YORK (January 14) -- A new study co-authored by researchers from the Wildlife Conservation Society's (WCS) Global Conservation Program and the University of British Columbia (UBC) Faculty of Forestry introduces a classification called Resistance-Resilience-Transformation (RRT) that enables the assessment of whether and to what extent a management shift toward transformative action is occurring in conservation.
A wide breadth of behaviors surrounding oral sex may affect the risk of oral HPV infection and of a virus-associated head and neck cancer that can be spread through this route, a new study led by researchers at the Johns Hopkins Kimmel Cancer Center suggests. These findings add nuance to the connection between oral sex and oropharyngeal cancer -- tumors that occur in the mouth and throat -- and could help inform research and public health efforts aimed at preventing this disease.
The higher a person's income, the more likely they were to protect themselves at the early stages of the Covid-19 pandemic in the United States, Johns Hopkins University economists find.
When it comes to adopting behaviors including social distancing and mask wearing, the team detected a striking link to their financial well-being. People who made around $230,000 a year were as much as 54% more likely to increase these types of self-protective behaviors compared to people making about $13,000.
ATLANTA--Compared to standard machine learning models, deep learning models are largely superior at discerning patterns and discriminative features in brain imaging, despite being more complex in their architecture, according to a new study in Nature Communications led by Georgia State University.
While new research from West Virginia University economists finds that presidential inaugurations have gained popularity as must-see tourist events in recent years, major security threats will keep visitors away for the inauguration of President-Elect Joe Biden.
Published in "Tourism Economics," the study, by Joshua Hall, chair and professor of economics, and economic doctoral student Clay Collins, examined the impact of the inaugurations of Barack Obama and Donald Trump on hotel occupancy in the Washington, D.C.-area.
To achieve full occupancy, hotels used to rely exclusively on experience, concentration and human abilities. Then came online booking, which made the reservation collection process faster, but did not solve the risk of turning down long stays because of rooms previously booked for short stays.
MADISON, Wis. -- As a new, apparently more transmissible version of the virus that causes COVID-19 has appeared in several countries, new research finds that the transmissibility of viral strains and the population density of a region will play big roles in how vaccination campaigns can help towns and cities return to more normal activities.
The findings suggest that directing vaccines toward densely populated counties would help to interrupt transmission of the disease. Current vaccination distribution plans don't take density into account.
A new University of Saskatchewan (USask) study has found that stretching is superior to brisk walking for reducing blood pressure in people with high blood pressure or who are at risk of developing elevated blood pressure levels.
Walking has long been the prescription of choice for physicians trying to help their patients bring down their blood pressure. High blood pressure (hypertension) is a leading risk factor for cardiovascular disease and among the top preventable risk factors affecting overall mortality.
