Researchers found that mice exposed to cat urine early in life can't avoid it later due to positive reinforcement and hormone changes. The molecule L-Felinine is responsible for this effect, blocking pregnancy and reducing litter size.
Scientists from TU Wien and Free University of Berlin developed a quantum tomography method to measure and describe large quantum systems precisely with few measurements. This technique uses continuous matrix product states, which represent a vanishingly small fraction of all possible states but are physically important.
Researchers explore nanocarriers and microbubbles for efficient thrombus treatment, addressing limitations of existing drugs. The review highlights potential solutions for improving outcomes in ischemic heart disease and stroke, where millions die annually.
A new study from Washington State University suggests that REM sleep plays a crucial role in converting waking experiences into lasting memories and abilities in young brains. The study found that brain circuits change in the visual cortex during exploration, but REM sleep is required to make those changes "stick".
Researchers have visualized the oldest known Old World monkey skull, revealing a tiny but remarkably wrinkled brain. The ancient creature's brain supports the idea that brain complexity can evolve before brain size in primates, contradicting conventional wisdom.
A two-hour emotional awareness course has been shown to significantly reduce the severity of crimes committed by juvenile offenders. The study found a 44% drop in crime severity six months after completion, suggesting that improving emotion recognition capabilities can lead to reduced aggression and instances of severe crime.
Researchers at Lomonosov Moscow State University discovered a new DNA repair mechanism that can detect and fix single-stranded breaks in histone-bound DNA. This breakthrough opens up new avenues for treating neurodegenerative diseases such as Alzheimer's.
New research from Cornell University suggests that farmers should wait 24 hours after a rain or irrigation to harvest crops, as this reduces the risk of exposure to the pathogen Listeria monocytogenes. By doing so, farmers can minimize the presence of Listeria on fresh produce and ensure consumer safety.
A team of researchers from the University of Southampton has been awarded a British Council Newton Fund grant to support groundbreaking research on infectious diseases in Malaysia. The project aims to develop vaccines and improve public health capacity, with potential benefits for the country's Ministry of Health.
A phase IIIb study has confirmed regorafenib's benefit in patients with previously treated metastatic colorectal cancer. The safety profile and progression-free survival were similar to phase III trial results, with a median duration of 2.5 months.
A new study found that a test can predict which rheumatoid arthritis patients will fail to respond to biologic drugs. Detecting low drug levels and anti-drug antibodies in the bloodstream can help adjust treatments.
A study at Umea University has successfully captured a protein structure previously impossible to study, providing insights into enzymes' catalytic capabilities. The discovery enables the development of designed enzymes for new chemical reactions in biotechnology.
Scientists have successfully imaged ultrafast unidirectionally rotating molecules at 100 billion per second, revealing a quantum wave-like nature. The high-resolution imaging reveals rotational wave packets with distinct angular velocities, showcasing the transition from quantum to classical behavior.
The Mainau Declaration 2015 on Climate Change states that nations must limit future global emissions and approve a new international agreement. The declaration warns of the consequences of unchecked climate change, which will overwhelm the Earth's ability to satisfy humanity's needs, leading to wholesale human tragedy.
