New water map of Mars will prove invaluable for future exploration

Science & Exploration 08/22/2022 443 views 11 likes A new map of Mars is changing the way we think about the planet’s watery past, and showing where we should land in the future. The map shows mineral deposits across the planet and has been painstakingly created over the last decade using data from ESA’s Mars … Read more

Oregon’s wildfire risk map emerges as new climate flashpoint

Credit: Unsplash/CC0 Public Domain A new map in Oregon that rated the wildfire risk of every tax lot in the state—labeling nearly 80,000 structures as high-risk—generated so much pushback from angry homeowners that officials abruptly retracted it, saying they had not done enough local outreach before publicizing the ambitious project. The rapid reversal, announced late … Read more

New global map of ant biodiversity reveals areas that may hide undiscovered species

An ant (species: Ectatomma tuberculatum) photographed in Costa Rica. Ants make up a large fraction of the total animal biomass in most terrestrial ecosystems, but researchers say that an understanding of their global diversity is lacking. This new study provides a high-resolution map that estimates and visualizes the global diversity of ants. Credit: Dr. Benoit … Read more

Cell map of human gonads identifies the cells involved in sex determination

+ cells were defined in an independent per-lineage reanalysis and projected onto this dataset (Fig. 3). Dashed lines outline the cell populations unique to the gonads. Doublets and low-quality control cells were removed. CoelEpi, coelomic epithelium; Endo, endothelial; Epi, epithelial; F. Leydig, fetal Leydig; Gi, gonadal interstitial; mesenchymal; Oi, ovarian interstitial; OSE, ovarian surface epithelium; … Read more

A New Map of Mars, Made From 51,000 Orbital Images

When NASA sent the Mars Reconnaissance Orbiter (MRO) to the red planet in 2006, the spacecraft took an instrument with it called CRISM—Compact Reconnaissance Imaging Spectrometer for Mars. CRISM’s job is to produce maps of Mars’ surface mineralogy. It’s been an enormous success, but unfortunately, the loss of its last cryocooler in 2017 means the … Read more

New method melds data to make a 3-D map of cells’ activities

A new method developed by Princeton researchers integrates gene expression information from multiple slices taken from the same tissue sample, providing a three-dimensional view of cell activities in health and disease, including the common skin cancer squamous cell carcinoma.

To refine water forecasts, Western cities map snow by plane

Credit: Pixabay/CC0 Public Domain At a tiny airport surrounded by mountains, a three-person crew takes off for the inaugural flight above the headwaters of the Colorado River to measure the region’s snow by air. Under the plane is a device that uses lasers, cameras and sensors to map snow and help drought-prone communities improve forecasts … Read more
