Engineers have shown that a widely used method of detecting single photons can also count the presence of at least four photons at a time. The researchers say this discovery will unlock new capabilities in physics labs working in quantum information science around the world, while providing easier paths to developing quantum-based technologies.

Drinking a cup of hot tea at least once a day may be linked to a significantly lower risk of developing the serious eye condition, glaucoma, finds a small study.

A new theoretical model explains the coupling between ions and electrons in the widely used conducting polymer PEDOT:PSS. The model has profound implications for applications in printed electronics, energy storage in paper, and bioelectronics.

Researchers have developed an optical medium in which multiple beams of light can autocorrect their properties without affecting other beams. This could lead to a dramatic reduction in the cost and energy consumption of high-speed internet communications.

Microscopes enhanced with artificial intelligence (AI) could help clinical microbiologists diagnose potentially deadly blood infections and improve patients' odds of survival, according to microbiologists.

When proteins misfold, accumulate and clump around insulin-producing cells in the pancreas, they kill cells. Now, researchers have obtained a structural snapshot of these proteins when they are most toxic, detailing them down to the atomic level.

Old forests that contain large trees and a diversity of tree sizes and species may offer refuge to some types of birds facing threats in a warming climate, scientists have found.

Researchers have identified a signaling pathway regulating cell migration and metastasis. Unexpected hair loss in a preclinical model helped them to identify the pathway. When cells within the skin that maintain hair follicles migrate too often, hair follicle maintenance is disrupted. Researchers speculated that this pathway might also play a role in cancer cell migration. Indeed, they showed that disrupting this pathway in preclinical models increased metastasis.

A new study indicates an essential role for a maternally inherited gene in embryonic development. The study found that zebrafish that failed to inherit specific genetic instructions from mom developed fatal defects earlier in development, even if the fish could make their own version of the gene.

Human memory has evolved so people better recall events encountered while they are thinking about raising their offspring, according to a new study.

Nearly six million Americans have bipolar disorder, and most have probably wondered why. After more than a decade of studying over 1,100 of them in-depth, a team of scientists has an answer -- or rather, seven answers.

According to a new study, almost 36 billion tons of soil is lost every year due to water, and deforestation and other changes in land use make the problem worse. The study also offers ideas on how agriculture can change to become a part of the solution from being part of the problem.

Human emissions of the potentially harmful trace metal vanadium into Earth's atmosphere have spiked sharply since the start of the 21st century due in large part to industry's growing use of heavy oils, tar sands, bitumen and petroleum coke for energy, a new Duke study finds. These emissions now exceed those from all natural sources combined. Growing evidence suggests exposure to vanadium-rich aerosols can impair respiratory functions and exacerbate conditions such as asthma or COPD.

Despite decades long prevention and treatment efforts, cardiovascular (CV) disease continues to be the leading cause of death worldwide. Early detection of CV disease can allow for interventions to prevent heart attack and stroke, including smoking cessation, medications such as a statins, blood pressure control, weight management, exercise, and improved diet. A new study focuses on a novel risk factor for cardiovascular disease that rarely receives attention -- erectile dysfunction.

Ion-trap technologies available today are suitable for building large-scale quantum computers, research shows. Scientists have introduced trapped-ion quantum error correction protocols that detect and correct processing errors.

Imaging at the nanoscale is important to a plethora of modern applications in materials science, physics, biology, medicine and other fields. Limitations of current techniques are, e.g. their resolution, imaging speed or the inability to look behind opaque objects with arbitrary shapes. Scientists have now demonstrated a method for meeting this challenge with stunning properties.

About one third of all medicine binds to the same type of receptor in the human body. An estimated three percent of the population have receptors of this type that are so genetically different that they are predisposed to altered, ineffective or adverse responses to medicine, a new study shows.
December 15th
When symmetries in quantum systems are spontaneously broken, the collective excitation modes change in characteristic ways. Researchers have now directly observed such Goldstone and Higgs modes for the first time.

One in two persons aged 65 and above has suboptimal levels of vitamin D in the blood and one in four older adults has suboptimal vitamin B12 levels.

A new genetic analysis of fungal yeast infections (candidiasis) from around the world has revealed surprising secrets about how these microbes reproduce and cause disease, according to a new study.
