The blood-brain barrier blocks the entry of antibodies into the brain. This limits the potential use of antibody therapeutics to treat brain diseases, such as brain tumors.
In a new study published in the Proceedings of the National Academy of Sciences, University of Utah (the U) biologists have developed a method for illuminating the intricate interactions of the synaptonemal complex in the nematode C. elegans.
Africa is on fire. It has been for thousands of years. The continent contains more than 50% of the total area on Earth that is burning, on average, and there is no sign of it stopping; indeed, the migrating, hemisphere-hopping African wildfire season is steadily increasing.
Fossils of a new group of animal predators have been located in the Early Cambrian Sirius Passet fossil locality in North Greenland. These large worms may be some of the earliest carnivorous animals to have colonized the water column more than 518 million years ago, revealing a past dynasty of predators that scientists didn't know existed.
Because same-sex sexual behavior does not result in offspring, evolutionary biologists have long wondered how the genes associated with this behavior have persisted in the human genome, and whether they will remain in the future.
Damage to crops caused by birds costs millions of dollars each year. Now, researchers from the University of Florida and the University of Rhode Island in the US are investigating the effectiveness of laser scarecrows—a high-tech solution using light to deter birds.
A new study published today in the journal Nature offers an unprecedented view of previously unmapped industrial use of the ocean and how it is changing.
The avocado has soared to unprecedented heights of popularity, gracing the plates of toast enthusiasts and health-conscious individuals worldwide. But what are the overlooked consequences of our latest food obsession?
A biomedical Egyptologist from The University of Manchester has fulfilled the mission of an illustrious Manchester anatomist from 1910, having by chance found his unique anatomical record of how ancient Nubians lived—and died—in Southern Egypt.
Chlorophyll plays a pivotal role in photosynthesis, which is why plants have evolved to have high chlorophyll levels in their leaves. However, making this pigment is expensive because plants invest a significant portion of the available nitrogen in both chlorophyll and the special proteins that bind it.
Dogs are humans' best friends. Need to quickly locate a bomb? There's a dog for that. Can't see very well? There's a dog for that. Searching for a lost hiker in the mountains or survivors in an earthquake, diagnosing illness, comforting the bereft—there are dogs for every need.
As human densities increase around the world, wildlife species are becoming more nocturnal to compensate. These adaptations allow wildlife to live in human-altered habitats but may result in unseen costs. Researchers at the University of Minnesota College of Biological Sciences conducted a case study on the conflict between humans and wildlife in East Africa better to understand the impact of human activities on wildlife.
The abandoned fieldstone walls of New England are every bit as iconic to the region as lobster pots, town greens, sap buckets and fall foliage. They seem to be everywhere—a latticework of dry, lichen-crusted stone ridges separating a patchwork of otherwise moist soils.
Perovskite materials are still attracting a lot of interest in solar cell applications. Now, the nanostructures of perovskite materials are being considered as a new laser medium. Over the years, light amplification in perovskite quantum dots has been reported, but most of the works present inadequate quantitative analysis.
We depend on catalysts to turn our milk into yogurt, to produce Post-It notes from paper pulp, and to unlock renewable energy sources like biofuels. Finding optimal catalyst materials for specific reactions requires laborious experiments and computationally intensive quantum chemistry calculations.
In 1950, during a lunchtime conversation with colleagues at the Los Alamos National Laboratory, famed physicist Enrico Fermi asked the question that launched a hundred (or more) proposed resolutions. "Where is Everybody?"
To limit global warming to 1.5°, the EU's Science Advisory Board on Climate Change recommends that Europe reduce its greenhouse gas emissions by 90%–95% by 2040 compared to 1990. Fossil fuels should be phased out as quickly as possible.
Local newspapers are key to keeping residents informed about civic affairs, and the threat of negative media coverage keeps nonprofit leadership salaries in check, according to new University at Buffalo School of Management research.
As many of us were reminded last summer when forest fires in Canada turned New York City's air to the color orange, air pollution is transported by the wind. Fortunately, here in the United States, the Commerce Clause of the Constitution gives the federal government the authority to regulate business practices that cross state lines.
The sun emitted a strong solar flare, peaking at 4:55 p.m. EST, on Dec. 31, 2023. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event.
As one of the top predators roaming Antarctica, the sizeable southern elephant seal has its fair selection of the menu. But it turns out they don't just want to eat anything and everything.
Like mail carriers who manage to deliver their parcels through snow, rain, heat and gloom, a critical group of mammalian proteins helps cells function properly even under less-than-ideal conditions.
On the first day of 2024, a 7.5 magnitude earthquake struck Japan, killing at least 57 people and destroying thousands of homes.
Scotland's climate is changing faster than scientists predicted, with increasing likelihood of more frequent and more extreme weather events, according to new analysis by The James Hutton Institute in Aberdeen.
Arenicola, or lugworms, make some of the most beautiful structures on the beach. Little piles of wet sand are cast in a swirl from their rear end as part of their feeding cycle.
