The first experimental demonstration of two schemes to enhance the longitudinal coherence of SASE-XFEL pulses shows that the SASE pulse bandwidth can be reduced by up to a factor of three.
A series of psychoacoustic and neuroimaging studies reveal the effect that the sound of Aztec skull whistles has on modern listeners; the sound, which is perceived as a mixture of voice-like, scream-like, and technological, triggers affective processing.
Can weight loss leave a lasting imprint on our fat cells?
Losing weight is often touted as a cornerstone of better health, particularly for people dealing with obesity and its associated health risks.
Anyone who has ever tried to get rid of a few extra kilos knows the frustration: the weight drops initially, only to be back within a matter of weeks—the yo-yo effect has struck. Researchers at ETH Zurich have now been able to show that this is all down to epigenetics.
Epigenetics is the part of genetics that’s based not on the sequence of genetic building blocks, but on small yet characteristic chemical markers on these building blocks. The sequence of building blocks has evolved over a long period of time; we all inherit them from our parents.
Using data and samples from volunteers, including Kaiser Permanente Washington members participating in the Adult Changes in Thought Study (ACT Study), the researchers used advanced genomic technologies and machine learning models to create a timeline of the cellular and molecular changes caused by…
Mapping the disease at the cellular level identifies possible new treatment targets.
People need to anticipate the revolution that’s coming in how humans and AI will collaborate to create discoveries, argues Sam Rodrigues.

Researchers in the Nanoscience Center at the University of Jyväskylä, Finland, have used machine learning and supercomputer simulations to investigate how tiny gold nanoparticles bind to blood proteins. The studies discovered that favorable nanoparticle-protein interactions can be predicted from machine learning models that are trained from atom-scale molecular dynamics simulations. The new methodology opens ways to simulate the efficacy of gold nanoparticles as targeted drug delivery systems in precision nanomedicine.
Hybrid nanostructures between biomolecules and inorganic nanomaterials constitute a largely unexplored field of research, with the potential for novel applications in bioimaging, biosensing, and nanomedicine. Developing such applications relies critically on understanding the dynamical properties of the nano–bio interface.
Modeling the properties of the nano-bio interface is demanding since the important processes such as electronic charge transfer, chemical reactions or restructuring of the biomolecule surface can take place in a wide range of length and time scales, and the atomistic simulations need to be run in the appropriate aqueous environment.
We are now more connected than ever, but also more lonely. Could AI companionship be the cure? In this episode, Emily Chang explores the future tech behind a growing market of relationships-on-demand.
Technology that once seemed like science fiction is rapidly becoming reality, transforming the very essence of our existence. In this four-part series, Emily Chang unravels the future of being human in an age of unprecedented innovation.

The book “Intelciety. Intelligent Society. Are We Ready for the Challenge?” explores the profound changes that artificial intelligence (AI) and other emerging technologies are causing in modern society. Vicente Ferreira da Silva addresses how these technologies are transforming various fields, from medicine and biotechnology to robotics and nanotechnology, and questions whether we are truly prepared to deal with these advances.
