scDEED assigns a reliability score to each 2D embedding to indicate how much the data point’s mid-range neighbors change in the 2D spaceThe article was co-authored with Christy Lee, Ph.D. student of Statistics at UCLA.Photo by Viktor Forgacs on Unsplasht-SNE (t-Distributed Stochastic Neighbor Embedding) and UMAP (Uniform Manifold Approximation and Projection) are non-linear dimensionality reduction techniques for visualizing high-dimensional data, particularly in the context of single-cell analysis for visualizing cell…

India's maiden solar mission, Aditya-L1, has achieved a significant milestone as the advanced sensors aboard the spacecraft successfully detected the coronal mass ejections (CMEs). Developed by the Indian Space Research Organisation (ISRO), the payload— Plasma Analyser Package for Aditya (PAPA)— played a pivotal role in capturing these crucial observations.PAPA is an energy and mass analyser designed for in-situ measurements of solar wind electrons and ions in the low energy range. Equipped with two sensors— the Solar…

This artist’s impression shows ultra-fast winds blasting out from the center of galaxy Markarian 817. These winds, moving at many millions of kilometers per hour, clear out interstellar gas from a vast region of space. Without this gas, the galaxy can’t form new stars and the black hole in the galactic center has little left to eat. Credit: ESAObservations reveal black holes can alter galaxies by ejecting gas, impeding star formation, with significant implications for understanding galactic evolution.Black holes are like…

Researchers have used off-the-shelf components to create a sensor device that is not only cost-effective but can quickly detect 32 different pathogens and has sensitivities on par with the state-of-the-art biosensors used in pathology labs. The novel device could have a range of applications, from monitoring the effectiveness of cancer therapies to predicting the course of viral illnesses.Diagnosing diseases early benefits patients and doctors. It enables treatment to slow disease progression and reduces the risk of…

Scientists at CERN are trialling a new type of robot that identify potential radiation leakages in environments challenging to navigate both for humans and other robots employed at the research centre. Called the CERNquadbot, the dog-like robot has successfully completed its radiation protection test at the North Area, the facility’s largest experimental zone. “There are large bundles of loose wires and pipes on the ground that slip and move, making them unpassable for wheeled robots and…

The Hubble Space Telescope has observed the smallest planet outside our solar system to contain water vapor in its atmosphere, a "landmark discovery" that brings astronomy a step closer to characterizing Earth-like worlds.At around twice Earth's diameter, planet GJ 9827d orbits a red dwarf star 97 light-years away in the constellation Pisces, NASA and the European Space Agency (ESA) said in statements on Thursday.The team behind the finding are examining two scenarios: either the planet is a "mini-Neptune" with a…

Nikon has taken its imaging and AI prowess in a unexpected direction with a new system that can warn farmers when a cow is about to give birth, Kyodo News has reported. It's designed to reduce the need to constantly check large numbers of pregnant cows during busy birthing seasons, helping farmers improve efficiency.The system, which costs 900,000 yen per year ($6,200) for a farm with around 100 cows, consists of a security-style camera married to an AI system. It uses a dedicated smartphone application that sounds an…

NASA astronomers have discovered an unexpected "signal" coming from outside our galaxy, which they can't explain.The scientists were analyzing 13 years of data from the Fermi Gamma-ray Space Telescope when they noticed the mysterious signal.It was "an unexpected and as yet unexplained feature outside of our galaxy," wrote Francis Reddy of NASA's Goddard Space Flight Center.The powerful telescope can detect gamma rays, which are huge bursts of energetic light thousands to hundreds of billions of times as great as our eyes…

DOI: 10.1016/j.ophoto.2023.100055 A team of researchers from TU Delft has succeeded in long-term mapping of beach topography to within a few centimeters. The unique dataset…

The biosensor and reader are designed to be used at home or at a point of care. The system can transmit results wirelessly to physicians, patients, and patient’s caregivers and family. Credit: David Baillot/University of California San DiegoThe next steps involve testing saliva and urine samples with the biosensor.An international team of scientists has created a handheld, non-invasive device that can detect biomarkers for Alzheimer’s and Parkinson’s Diseases. This biosensor can also wirelessly send the findings to a…
