DAMPE satellite reveals cosmic rays share spectral break near 15 teravolts

A century after their discovery, cosmic rays—particles of extreme energy originating from the far reaches of the universe—remain a mystery to scientists. The DAMPE (Dark Matter Particle Explorer) space telescope is tackling this phenomenon, particularly investigating the role that dark matter may play in their formation. This international mission, which includes the University of Geneva (UNIGE), has made a major breakthrough by highlighting a universal feature of these particles. The results are published in the journal Nature.

Cosmic rays are the most energetic particles observed in the universe, far surpassing the energies of particles produced by man-made accelerators on Earth. Their exact origin is still under study, and it is believed that they originate from extreme astrophysical phenomena, such as supernovae, black hole jets, or pulsars.

The DAMPE space telescope, launched in December 2015, aims to provide answers regarding the origin and nature of these cosmic rays. This space mission, with the astrophysics group from the Department of Nuclear and Particle Physics (DPNC) at the University of Geneva (UNIGE) being one of its main contributors, has made a crucial breakthrough. Through the analysis of high-precision measurements collected by the telescope, scientists have identified a universal feature in the energy spectra of primary cosmic ray nuclei, ranging from protons to iron.

Abstract: SLC26A4-gene mutations are a frequent cause of hereditary HearingLoss

SLC26A4-gene mutations are a frequent cause of hereditary HearingLoss.

https://doi.org/10.1172/JCI193812 Here, Tsai et al. report that targeted AAV delivery to the endolymphatic sac and cochlear lateral wall restores auditory physiology and ameliorates cochlear pathology in a mouse model of Slc26a4-related deafness. Pendred syndrome DFNB4.

The image shows an AAV-GFP–transduced spiral prominence, a structure within the cochlear lateral wall. GFP (green) marks successfully transduced cells, phalloidin-568 (red) labels the actin cytoskeleton, and DAPI (blue) stains nuclei, highlighting efficient gene transfer to inner ear tissues essential for auditory function.

Diabetes flips immune cells from repair to inflammation in peripheral artery disease, study finds

Type 2 diabetes can turn immune cells that help with tissue repair and anti-inflammatory responses into triggers of chronic inflammation. A recent study investigated why people with type 2 diabetes are at a higher risk of severe complications from peripheral artery disease (PAD).

PAD is a common circulatory condition in which plaque buildup narrows the arteries, reducing blood flow, usually in the legs. This can lead to lower extremity infections and the formation of non-healing ulcers in people with diabetes.

Using RNA-sequencing and gene mapping, researchers discovered that diabetes causes certain immune cells called macrophages that express the protein TREM2 to reprogram their behavior from helping cells repair to causing harmful inflammation and preventing blood vessels from healing. The findings were published in Science Translational Medicine.

Fascinating new research suggests artificial neurodivergence could help solve the AI alignment problem

A new study suggests the key to safe AI isn’t perfect obedience, but cognitive diversity. Researchers propose that creating “neurodivergent” AI ecosystems, where systems check and balance each other, offers a pragmatic solution to the alignment problem.

Brain-inspired chip could reduce AI energy use by 70%

Replicating the brain’s capabilities, an impossible task, may theoretically require thousands of H100, one of NVIDIA’s most powerful GPUs. At 700 watts per chip, we are looking at power consumption in the megawatt range. The brain runs on 20 watts. Scientists have taken inspiration from this remarkable organ to create chips that could cut conventional energy use by 70%.

Researchers at the University of Cambridge have developed a new brain-inspired nanoscale device that they say could dramatically reduce the enormous energy demands of artificial intelligence hardware. The team created an ultra-low-power “memristor”: a device that can both store and process information in the same location, much like synapses in the human brain.

In conventional computing architectures, memory and processing units are physically separated, requiring data to shuttle back and forth between these units for every task. This seemingly simple process consumes enormous amounts of electricity and is a significant contributor to AI’s exploding power demands.
