Quantum Dot Breakthrough Makes Infrared Lasers Affordable and Scalable

Posted by in categories: chemistry, quantum physics

Researchers have developed a new laser technology using large colloidal quantum dots of lead sulfide to emit coherent light in the extended short-wave infrared range.

This innovation promises cheaper, scalable laser solutions compatible with silicon CMOS platforms, covering a broader wavelength range without altering chemical compositions, and eliminating the need for costly femtosecond laser amplifiers.

Scientists Discover Genetic Changes Linked to Autism, Schizophrenia

Posted by in categories: biotech/medical, genetics, health, neuroscience

The Tbx1 gene influences brain volume and social behavior in autism and schizophrenia, with its deficiency linked to amygdala shrinkage and impaired social incentive evaluation.

A study published in Molecular Psychiatry has linked changes in brain volume to differences in social behavior associated with psychiatric conditions like autism spectrum disorder and schizophrenia.

The research, led by Noboru Hiroi, Ph.D., a professor in the Department of Pharmacology at the Joe R. and Teresa Lozano Long School of Medicine at The University of Texas Health Science Center at San Antonio (UT Health San Antonio), revealed that a deficiency in a specific gene was connected to social behavior differences in mice. These behavioral differences are similar to those often observed in psychiatric disorders.

What’s in Your Honey? A New Study Finds More Than Just Sweetness

Posted by in category: food

Inside every jar of honey lies a taste of the local environment. Its sticky-sweet flavor is shaped by the flowers that nearby bees choose to sample. However, a new study from Tulane University has revealed that honey can also provide insights into local pollution.

The study, published in Environmental Pollution, analyzed 260 honey samples from 48 states for traces of six toxic metals: arsenic, lead, cadmium, nickel, chromium, and cobalt. None of the samples contained unsafe levels of these metals based on a typical serving size of one tablespoon per day, and the concentrations in the United States were generally lower than global averages. Still, researchers identified regional variations in toxic metal distribution: the highest arsenic levels were detected in honey from a cluster of Pacific Northwest states (Oregon, Idaho, Washington, and Nevada); the Southeast, including Louisiana and Mississippi, showed the highest cobalt levels; and two of the three highest lead levels were found in samples from the Carolinas.

Overall, the study highlights a potential dual role for honey as both a food source and a tool for monitoring environmental pollution.

Unlocking the Sun’s Fiery Secrets: NASA’s PUNCH Mission Set for Early 2025 Launch

Posted by in categories: energy, satellites

Launching in February 2025, NASAs PUNCH mission will study the Sun’s corona and solar wind with four satellites.

NASA and SpaceX plan to launch NASA’s PUNCH mission (Polarimeter to Unify the Corona and Heliosphere) in late February 2025 aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.

The PUNCH mission consists of four small satellites designed to enter low Earth orbit and capture 3D, global views of the Sun’s corona. By studying how mass and energy in the corona become the solar wind, scientists hope to gain new insights into solar activity and its effects on space weather.

A New Era in Amphibian Biology: Scientists Use Viruses To Study Frog Nervous System Development

Posted by in categories: biotech/medical, evolution, genetics, neuroscience

Researchers have developed a method using viruses to track neuronal development in frogs, shedding light on the evolution of vertebrate nervous systems and offering comparative insights with mammals.

Although viruses are typically associated with illnesses, not all viruses are harmful or cause disease. Some are instrumental in therapeutic treatments and vaccinations. In scientific research, viruses are often used to infect certain cells, genetically modify them, or visualize neurons in the organism’s central nervous system (CNS)—the command center made up of the brain, spinal cord, and nerves.

The highlighting process has now been successfully applied to amphibians, which are crucial for understanding the brain and spinal cord of tetrapods—four-limbed animals, including humans. This has been shown in a new study by an international EDGE consortium jointly led by the Sweeney Lab at the Institute of Science and Technology Austria (ISTA) and the Tosches Lab at Columbia University.
