How the freezer factors into lowering food waste
Putting extra holiday cookies and leftovers in the freezer will not only extend their shelf life -- it could also put a dent in the U.S. household tendency to throw away edible food, a new study suggests.

Gene editing tool reduces Alzheimer's plaque precursor in mice
A new gene editing tool that helps cellular machinery skip parts of genes responsible for diseases has been applied to reduce the formation of amyloid-beta plaque precursors in a mouse model of Alzheimer's disease, researchers report.
Largest magnetic anisotropy of a molecule measured at BESSY II
At the Berlin synchrotron radiation source BESSY II, the largest magnetic anisotropy of a single molecule ever measured experimentally has been determined. The larger this anisotropy is, the better a molecule is suited as a molecular nanomagnet. Such nanomagnets have a wide range of potential applications, for example, in energy-efficient data storage.
Propranolol reduces tremors in Parkinson's disease
The standard medication levodopa does not always work against tremors in Parkinson's disease, especially in stressful situations. Propranolol, however, does work during stress, providing insight into the role of the stress system in tremors. MRI scans reveal that propranolol directly inhibits activity in the brain circuit that controls tremors. Doctors may consider this medication when levodopa is ineffective.
Public shows greater acceptance of RSV vaccine as vaccine hesitancy appears to have plateaued
A year after becoming available, vaccines to protect against RSV in newborns and older adults are being more widely accepted by the American public, according to a new health survey.
Foundational technology to make cancer cells revert to normal cells?
A research team has developed a groundbreaking technology that can treat colon cancer by converting cancer cells into a state resembling normal colon cells without killing them, thus avoiding side effects.
Individual leopards can be identified by their roars
In the first large-scale paired camera trap and autonomous recording survey for large African carnivores, researchers were able to identify individual leopards by their vocalizations with 93% accuracy.
Researchers develop tool to fast-track measurement of protein interactions for drug discovery
Researchers have created a platform, called SIMPL2, that revolutionizes the study of protein-protein interactions by simplifying detection while improving measurement accuracy. While protein-protein interactions have previously been considered 'undruggable' using small molecules, the platform addresses this challenge by facilitating the measurement of these interactions -- improving our understanding of the types of molecules needed to control them.
New research identifies key cellular mechanism driving Alzheimer's disease
Researchers have unveiled a critical mechanism that links cellular stress in the brain to the progression of Alzheimer's disease (AD). The study highlights microglia, the brain's primary immune cells, as central players in both the protective and harmful responses associated with the disease.
Hospitals that have adopted the Center for Medicare and Medicaid (CMS) 'hospital-at-home' program, which serves as an alternative to admission to brick-and-mortar facilities, are concentrated in large, urban, not-for-profit, and academic hospitals, highlighting need for targeted incentives to expand program to smaller, rural, and non-teaching hospitals.
Twisted Edison: Bright, elliptically polarized incandescent light
Bright, twisted light can be produced with technology similar to an Edison light bulb, researchers have shown. The finding adds nuance to fundamental physics while offering a new avenue for robotic vision systems and other applications for light that traces out a helix in space.
Brain map clarifies neuronal connectivity behind motor function
Scientists traced connectivity between neurons to identify how the brain communicates with the spinal cord to control motor function.
Researchers find compromised indoor air in homes following Marshall Fire
A new study finds gases harmful to human health lingered for weeks following the fire.
Three years after the Dec. 30, 2021, Marshall Fire destroyed more than 1,000 homes in Boulder County, two new studies offer insight into what happens to air quality and health in the aftermath of urban wildfires.
Unraveling the power and influence of language
A choice was made to include each word in this sentence. Every message, even the most mundane, is crafted with a specific frame in mind that impacts how the message is perceived. The study of framing effects is a multidisciplinary line of research that investigates when, how, and why language influences those who receive a message and how it impacts their response.
