Cryo-electron tomography (cryo-ET) is a powerful technique that allows researchers to visualize and analyze cellular structures in their natural environment. It has been used to study a wide range of biological processes, including protein folding helpers known as chaperonin complexes. Researchers at the MPI of Biochemistry in Martinsried and the University Medical Center Göttingen recently

The process of autonomous assembly of individual particles into complex patterns is crucial for many fundamental processes of life, as well as their synthetic counterparts in nanotechnology. Professor Erwin Frey, a physicist at LMU Munich, has been studying the fundamental principles of self-organization in collaboration with his team. Their research has led to the development
Black holes in the centers of galaxies, such as the Milky Way, are known for their occasional feasting on nearby stars. This event leads to a dramatic and complex process known as a tidal disruption event, where the star is spaghettified and torn apart as it plunges towards the supermassive black hole. Despite initial theories
Fear is a powerful emotion that triggers a series of chemical reactions within our bodies. It prepares us to respond to threats and dangers in our environment. However, when fear becomes uncontrollable, it can lead to anxiety disorders and post-traumatic stress disorder (PTSD). These conditions can lock individuals into a cycle of fear and trauma,
The ratchet mechanism is a complex energy conversion system that plays a crucial role in various mechanical systems. It essentially converts disorderly or random motion into orderly and directed movement through a process known as spontaneous rectification. This mechanism typically consists of a gear and a pawl, with the pawl restricting the movement of the
Recent research conducted by Western Sydney University has uncovered concerning levels of PFOS (perfluorooctane sulfonate) chemical contamination in the livers of deceased platypuses across eastern New South Wales. PFOS, a type of PFAS (per-and poly-fluoroalkyl substances), was detected in liver samples from nine deceased platypuses collected over a two-and-a-half-year period. Lead researcher Katherine Warwick from
Polymers are unique materials that consist of long chains of molecules, and it is the interactions between these chains that determine the properties of the polymer. Traditionally, external forces acting on polymers have been seen as destructive, such as stretching a polymer which can weaken the material by breaking apart its chains. However, scientists have
The world of technology is constantly evolving, and one such innovation that is set to revolutionize everyday objects is printed electronics. These electronic circuits in thin and bendable sheets have the potential to bring about remarkable changes in how we interact with the world around us. From smart phones with flexible displays to solar cells
AMD’s recent acquisition of server maker ZT Systems for $4.9 billion marks a significant move by the chipmaker to bolster its artificial intelligence capabilities. With the aim of rivaling tech giant Nvidia, AMD is looking to tap into the growing demand for AI technology in the market. The deal includes a contingent payment of up
Black holes have always been known to be voracious beings, devouring anything that dares to come too close. Stars collapsing past the event horizon of a black hole often result in spectacular displays of death throes, emitting flashes of light that signal their demise. However, in some rare cases, a star manages to avoid being
Alzheimer’s disease is a neurodegenerative condition that has puzzled researchers for decades. The direct cause of brain damage in Alzheimer’s has remained elusive, despite extensive research efforts. Recent findings from a team at Emory University in the US may shed light on the role of protein accumulation in the development of Alzheimer’s disease. For years,
Plastics have been a staple in modern manufacturing for decades, but with increasing awareness of their environmental impact, the demand for eco-friendly alternatives has skyrocketed. Researchers at The University of Warwick have been at the forefront of this search, making significant progress in identifying sustainable alternatives to traditional plastics. In response to growing environmental concerns,
On Monday, the Earth experienced an intense solar storm that was classified as a level-four geomagnetic storm by the US National Oceanic and Atmospheric Administration (NOAA). This heightened level of geomagnetic activity has the potential to bring the northern lights further south than normal, with states like Alabama and northern California possibly being able to
In a recent ruling, a US judge declared Google as a monopoly, using its power to solidify its market position. This places the US regulator in alignment with the European Commission’s stance on tech giants like Google, Meta, and Amazon. The consensus among regulators is that these companies’ business models lead to monopolistic control over
Boeing’s newly appointed CEO, Kelly Ortberg, is making strides towards rebuilding the relationship with one of the key unions representing tens of thousands of its workers. Ortberg recently met with the presidents of IAM 751 & W24 for a productive conversation in Seattle, expressing his commitment to resetting the relationship and reaching a new labor
