In mammals in general, large ones live longer and become the parents of several large, slowly developing young, such as elephants. In contrast, small short-lived mammals, typically mice, tend to have large litters of small young that grow and mature quickly. Bats are an exception: although small, they live long lives - even several decades - and reproduce in a similar way to large mammals.
The system could provide teleoperated endovascular treatment to patients during the critical time window after a stroke begins.
Cuckoos are brood parasites, which means they lay their own eggs in the nests of other bird species. In the Czech Republic, most commonly in great reed warblers´ nests. Almost every third parasitized nest happens to have multiple cuckoo eggs.
Microbes that safely break down antibiotics could prevent opportunistic infections and reduce antibiotic resistance.
An international team of parasitologists and medicinal chemists from the BIOCEV Centre has developed and successfully tested a substance against a deadly parasite. Naegleria fowleri attacks the human brain and despite all modern treatments, 97% of cases end fatally. The new substance has been shown to cure the infection in mice. Along with it, scientists have discovered other anti-parasitic agents that could be used against malaria or sleeping sickness in the future.
Northwestern University researchers have developed a sustainable, two-step process that can upcycle organic carbon waste such as lignin, which could allow it to be used in pharmaceuticals for drug or chemical delivery.
The phenomenon of mating causing "jet lag" in female fruit flies and changes in their behavior, first reported by Cornell University researchers, comes down to how the female flies usually go about their days and how that changes when they encounter a male, one of the researchers said.
A team of researchers from Washington State University (WSU) has developed a semi-submersible unmanned vehicle that eventually could change the way people travel in water.
When artificial intelligence is tasked with visually identifying objects and faces, it assigns specific components of its network to face recognition — just like the human brain.
A new analysis shows how milk-producing cells change over time in nursing mothers.
Yogesh Surendranath and his team are bringing powerful techniques of electrochemistry to bear on the problem of designing catalysts for sustainable fuels.
Electric fields may represent information held in working memory, allowing the brain to overcome “representational drift,” or the inconsistent participation of individual neurons.
Cannabinoid receptors help the brain’s dopamine system establish key connections after birth, a new mouse study suggests.
Named after a goddess of the dawn, the Thesan simulation of the first billion years helps explain how radiation shaped the early universe.
These cells, located in the brain’s striatum, appear to help with decision-making that requires evaluating risks and benefits.
The discovery could help researchers engineer exotic electrical states such as unconventional superconductivity.
Inspired by the human ear, a new acoustic fabric converts audible sounds into electrical signals.
Researchers create a mathematical framework to examine the genome and detect signatures of natural selection, deciphering the evolutionary past and future of non-coding DNA.
New research provides insights into how quantum mechanics can control ultracold chemistry.
An MIT study identifies ways that lawyers could make their written documents easier for the average person to read.
