Depression is a common mental health condition that mainly affects young adults. It is a significant risk factor for suicide, the leading cause of death in young adults. A new study assessed the impact of a Mediterranean diet on the symptoms of depression in young men. They were surprised to see that young men with…
Ocean memory, the persistence of ocean conditions, is a significant source of predictability in the climate system beyond weather time scales. It is often used for predicting ocean conditions. A study by a University of Hawaiʻi at Mānoa atmospheric scientist suggests that the world’s ocean is steadily losing its year-to-year memory due to global warming.…
Glioblastoma multiforme (GBM) is the most common devastating brain tumor in adults. It mainly arises from the glial cells in the brain. People who suffer from Glioblastoma Multiforme have a five percent survival rate over five years. This figure has not been improved for decades. A new study by the University of Surrey has shown…
Preserving photon statistics of quantum optical states during frequency conversion is critical in modern quantum technologies, as quantum networks sometimes demand the interfacing of many subsystems operating in significantly different spectral regions. However, current approaches offer only very small frequency shifts and limited tunability. They also suffer from high insertion loss and Raman noise originating…
In March 2018, astronomers observed a sudden change in brightness of a galaxy located 239 million light-years away. Known as 1ES 1927+654, the galaxy had brightened by 100 in visible light. Further observation by the NASA-funded Asteroid Terrestrial-impact Last Alert System revealed that the eruption started much earlier, at the end of 2017. Reanalysis of…
Shallow, dynamic subglacial water systems provide lubrication that facilitates the movement of overlying ice. Antarctica’s fast-flowing ice streams drain the ice sheet, controlling the velocity of subglacial water systems. The current understanding of these water systems is confined to the shallow parts around the ice-bed interface, although deeper groundwater could also influence ice streaming. A…
NASA has confirmed the presence of water molecules in the sunlit areas of the Moon, indicating that water is widely distributed across the lunar surface. A majority of the lunar water is generally believed to have been deposited by asteroids and comets that collided with the Moon during the Late Heavy Bombardment period. During that…
Flirting involves various signals communicated between individuals to attract potential mates. Different flirtation tactics have been described. But, they are not always fruitful for everyone and in every situation. A new study by NTNU, Bucknell University in Pennsylvania, and the State University of New York at Oswego, found one of the best strategy to flirt.…
Stem cells can transform into any cell in the body. Treatment with a predetermined series of signaling molecules can direct stem cell differentiation and self-organization into organoids that resemble the body’s organs when grown in a cultural environment that encourages aggregation. Using human induced pluripotent stem (iPS) cells, scientists at Osaka University have developed three-dimensional…
The polariton is a quasiparticle formed by the strong coupling to a matter excitation. It is a crucial ingredient of emergent photonic quantum systems ranging from semiconductor nanophotonics to circuit quantum electrodynamics. Using the interaction between polaritons has led to the realization of superfluids of light and strongly correlated phases in the microwave domain, with…
