The glorious, billowing Southern Ring Nebula is the cocoon of a dying star, and it has a secret. Scientists have found that this nebula has a double ring structure that shows not one, but possibly three stars at its heart. The Southern Ring Nebula, also designated NGC 3132, is a planetary nebula located about 2,000 … Read more
Summary: Researchers have pioneered a method to enhance the generation of dopaminergic neurons, crucial for the treatment of Parkinson’s disease, by targeting specific receptors within the Wnt signaling pathway. Using synthetic antibodies, the team successfully directed stem cell differentiation in the midbrain to produce these key neurons, which are critical to brain health and are … Read more
A temperature gradient is applied to a CrSBr thin film to measure its thermoelectric response. Credit: Alessandra Canetta Thermoelectric systems are a green and sustainable way to harvest energy from any form of heat that would otherwise be wasted. At the core of this energy conversion process is the so-called Seebeck effect, which describes the … Read more
It is logical that stars formed from the same cloud of material have the same metallicity. This fact underpins some avenues of astronomical research, such as the search for the brothers of the Sun. But for some binary stars, that’s not always true. Their composition can be different despite forming from the same reservoir of … Read more
