Scientists have discovered an ancient lake bed deep beneath the Greenland ice
Scientists have detected what they say are the sediments of a huge ancient lake bed sealed more than a mile under the ice of northwest Greenland--the first-ever discovery of such a sub-glacial feature anywhere in the world.

Stanford researchers develop DNA approach to forecast ecosystem changes
The rapid, low-cost technique is the first to analyze DNA left behind in animals' feces to map out complex networks of species interactions in a terrestrial system. It could help redefine conservation as we know it, identify otherwise hard-to-find species and guide a global effort to rewild vast areas. WATCH VIDEO:

Blue whirl flame structure revealed with supercomputers
Main structure and flow structure of 'blue whirl' flame revealed through supercomputer simulations. Flame simulations entailed four million CPU hours distributed over the Deepthought2 system from the University of Maryland; the Thunder system from the Air Force Research Laboratory; and Stampede2 of TACC allocated through NSF-funded XSEDE. Further research on blue whirls might help scientists develop ways to burn fuels more cleanly.

Implantable sensor could measure bodily functions -- and then safely biodegrade
Sensors that monitor a patient's condition during and after medical procedures can be expensive, uncomfortable and even dangerous. Now, an international team of researchers has designed a highly sensitive flexible gas sensor that can be implanted in the body -- and, after it's no longer needed, safely biodegrade into materials that are absorbed by the body.

Maunakea telescopes confirm first brown dwarf discovered by radio observations
A collaboration between the LOw Frequency ARray (LOFAR) radio telescope in Europe, the Gemini North telescope, and the NASA InfraRed Telescope Facility (IRTF), both on Maunakea in Hawai'i, has led to the first direct discovery of a cold brown dwarf from its radio wavelength emission. Along with paving the way for future brown dwarf discoveries, this result is an important step towards applying radio astronomy to the exciting field of exoplanets.

Researchers isolate and decode brain signal patterns for specific behaviors
A standing challenge has been isolating patterns in brain signals that relate to a specific behavior, such as finger movements. Researchers have developed a machine learning algorithm that resolved this challenge by uncovering neural patterns missed by other methods. This could both enable new neuroscience discoveries and enhance future brain-machine interfaces.

How ancient dust from the sea floor helps to explain climate history
Iron-containing dust can fuel ocean productivity. Researchers now show that dust travelled a long way in the South Pacific Region during the last Ice Age. Based on analyses of sediment cores they identified the area that is now north-west Argentina as primary source of dust. The results help explain glacial cooling and climate history.

New tool detects unsafe security practices in Android apps
Computer scientists at Columbia Engineering have shown for the first time that it is possible to analyze how thousands of Android apps use cryptography without needing to have the apps' actual codes. The team's new tool, CRYLOGGER, can tell when an Android app uses cryptography incorrectly--it detects the so-called 'cryptographic misuses' in Android apps. When given a list of rules that should be followed for secure cryptography, CRYLOGGER detects violations of these rules.

Wound-healing biomaterials activate immune system for stronger skin
Researchers at Duke University and the University of California, Los Angeles, have developed a biomaterial that significantly reduces scar formation after a wound, leading to more effective skin healing. This new material, which quickly degrades once the wound has closed, activates an adaptive immune response that can trigger regenerative wound healing, leaving behind stronger and healthier healed skin.

Migration and molt affect how birds change their colors
Before their big journey, many birds molt their bright feathers, replacing them with a more subdued palette. Watching this molt led scientists to wonder how feather color changes relate to the migrations many birds undertake twice each year.

Final dance of unequal black hole partners
Lousto and James Healy (both of Rochester Institute of Technology) used the Frontera supercomputer to model for the first time a black hole merger of two black holes with very different sizes (128:1). The research required seven months of constant computation. The results, published in Physical Review Letters, predicts the gravitational waves such a merger would produce, as well as characteristics of the resulting merged black hole.

Indian fossils support new hypothesis for origin of hoofed mammals
New research published today in the Journal of Vertebrate Paleontology describes a fossil family that illuminates the origin of perissodactyls - the group of mammals that includes horses, rhinos, and tapirs. It provides insights on the controversial question of where these hoofed animals evolved, concluding that they arose in or near present day India.

Soil carbon changes in transition areas suggest conservation for Amazon, scientists say
Conservation efforts on the edges of the Amazon forest, especially in light of recent deforestation by human disturbance, could help the region weather the storm of climate change, researchers say. That assessment, led by researchers at the University of Oregon, comes from an analysis of vegetation changes and carbon isotope signatures in the soil at 83 sites.

Global-scale animal ecology reveals behavioral changes in response to climate change
An international team including University of Maryland biologists developed a data archive of animal movement studies from across the global Arctic and sub-Arctic and conducted three case studies that revealed surprising patterns and associations between climate change and the behavior of golden eagles, bears, caribou, moose and wolves. This work, which appears in the November 6, 2020, issue of the journal Science demonstrates both the feasibility and importance of global-scale animal ecology.

When new males take over, these female primates hurry up and mature
Most mammals--including humans and other primates--reach sexual maturity early or late depending on lots of different factors, such as how much food there is to eat. Now, researchers studying close primate relatives of baboons known as geladas have shown for the first time that females of this species suddenly hurry up and mature when a new male enters the picture. Their findings are reported in the journal Current Biology on November 5th.
