Researchers have engineered string-like resonators capable of vibrating longer at ambient temperature than any previously known solid-state object -- approaching what is currently only achievable near absolute zero temperatures. Their study pushes the edge of nanotechnology and machine learning to make some of the world's most sensitive mechanical sensors. Read more ›

Researchers trained an AI model to accurately predict male fruit flies' courtship behavior in response to any sight of a female. This breakthrough offers new insight into how the brain processes visual data and may someday pave the way for artificial vision technology. Read more ›

Scientists have discovered that when metal is struck by an object moving at a super high velocity, the heat makes the metal stronger. The finding could lead to new approaches to designing materials for extreme environments, such as shields that protect spacecraft or equipment for high-speed manufacturing. Read more ›

Many processes in the deep sea are not yet well understood, and the role of microbial communities in particular is often a big unknown. This includes, for example, how organic material that sinks from the water surface to the ocean floor is metabolised -- an important building block for a better understanding of the global carbon cycle.

The researchers started with 50 samples collected from 1941 to 1947, and they found that the samples contained seven different Streptococcus species, including two subspecies of S. dysgalactiae. Interestingly, the researchers found some of the samples were resistant to the antibiotic tetracycline and did not carry antibiotic resistance genes typically seen in today's antibiotic-resistant bacterial strains. Since these samples were collected prior to the antibiotic era, the results add to... Read more ›

Maize can grow successfully in very different local conditions. An international study has now demonstrated the important role of the plant root system. The researchers analyzed more than 9,000 varieties in the study and were able to show that their roots varied considerably -- depending on how dry the location is where each variety was cultivated. They were also able to identify an important gene that plays a role in... Read more ›

The discovery of thousands of stone artefacts and animal bones in a deep cave in Timor Island has led archaeologists to reassess the route that early humans took to reach Australia. Researchers dated and analysed the artefacts and sediment at the Laili rock shelter in central-north Timor-Leste, north of Australia, to pinpoint the arrival of the colonists. Read more ›

In a new study, a team of researchers used research on fossilizing techniques to create a new method for sealing cracks and fractures in rocks and bedrock using a 'concretion-forming resin'. This innovative technique has applications in a wide range of industries, from tunnel construction to long-term underground storage of hazardous materials. Read more ›

A new study reveals that cows who are cuddled as therapy animals showed a strong preference for interactions with women when compared to men. In turn, the research, which opens a new era on whether some therapies may be initially stronger based upon gender and not procedure, highlighted that the women also reported greater attachment behaviors towards the steers.

New research has found that thousands of DNA sequences originating from ancient viral infections are expressed in the brain, with some contributing to susceptibility for psychiatric disorders such as schizophrenia, bipolar disorder, and depression. Read more ›

I'm not touching you! When another person's finger hovers over your skin, you may get the sense that they're touching you, feeling not necessarily contact, but their proximity. Similarly, researchers have designed a soft, flexible film that senses the presence of nearby objects without physically touching them. The study features the new sensor technology to detect eyelash proximity in blink-tracking glasses. Read more ›

Use of the greenhouse gas CO2 as a chemical raw material would not only reduce emissions, but also the consumption of fossil feedstocks. A novel metal-free organic framework could make it possible to electrocatalytically produce ethylene, a primary chemical raw material, from CO2. Nitrogen atoms with a particular electron configuration play a critical role for the catalyst. Read more ›

Scientists have used breast cancer cells' weakness against themselves by linking a tumor-selective antibody with a cell-killing drug to destroy hard-to-treat tumors. Read more ›

Researchers describe cell-in-cell phenomena in which one cell engulfs and sometimes consumes another. The study shows that cases of this behavior, including cell cannibalism, are widespread across the tree of life. The findings challenge the common perception that cell-in-cell events are largely restricted to cancer cells. Rather, these events appear to be common across diverse organisms, from single-celled amoebas to complex multicellular animals. Read more ›

To achieve global biodiversity targets, conservationists and governments must prioritize the establishment and effective management of large, interconnected protected areas with high ecological integrity, researchers argue in a new essay. Read more ›

A new laboratory study suggests that human body lice are more efficient at transmitting Yersinia pestis, the bacterium that causes plague, than previously thought, supporting the possibility that they may have contributed to past pandemics. Read more ›
