Earlier in the week, NOAA's National Hurricane Center was monitoring a low-pressure system in the Gulf of Campeche that has now moved along the Texas and Louisiana coastlines, bringing heavy rainfall. On June 5, NASA used a constellation of satellites to estimate that rainfall.
On June 5, the National Weather Service National Prediction Center in College Park, Maryland noted that there is a "High risk for flash flooding across parts of southeast Texas and southern Louisiana Today into Tonight."
Estimating Heavy Rainfall
The first humans in North America arrived from Asia some time before 14,500 years ago. The next major stream of gene flow came about 5000 years ago, and is known to archaeologists as Paleo-Eskimos. About 800 years ago, the ancestors of the present-day Inuit and Yup'ik people replaced this population across the Arctic. By about 700 years ago, the archaeological evidence for the Paleo-Eskimo culture disappeared. Their genetic legacy in living populations has been contentious, with several genetic studies arguing that they made little contribution to later North Americans.
A team of researchers encoded their specialized knowledge into the computer game Foldit to enable citizen scientists to successfully design synthetic proteins for the first time.
The initial results of this collaboration appear in the June 5 issue of Nature. The Institute for Protein Design at the University of Washington School of Medicine led the multi-institutional effort.
Earth's outer layer is composed of giant plates that grind together, sliding past or dipping beneath one another, giving rise to earthquakes and volcanoes. These plates also separate at undersea mountain ridges, where molten rock spreads from the centers of ocean basins.
But this was not always the case. Early in Earth's history, the planet was covered by a single shell dotted with volcanoes--much like the surface of Venus today. As Earth cooled, this shell began to fold and crack, eventually creating Earth's system of plate tectonics.
The problem of cleaning up toxic polyfluorinated alkyl substances (PFAS) pollution - commonly used in non-stick and protective coatings, lubricants and aviation fire-fighting foams - has been solved through the discovery of a new low-cost, safe and environmentally friendly method that removes PFAS from water.
Organic foods are increasingly popular -- and pricey. Organic fruits and vegetables are grown without synthetic pesticides, and because of that, they are often perceived to be more healthful than those grown with these substances. But not all foods with this label are fully pesticide free, and it can be challenging to detect low amounts of the substances. Now, scientists report in ACS' Journal of Agricultural and Food Chemistry a new strategy to determine organic authenticity.
Researchers have demonstrated that vehicle armor using composite metal foam (CMF) can stop ball and armor-piercing .50 caliber rounds as well as conventional steel armor, even though it weighs less than half as much. The finding means that vehicle designers will be able to develop lighter military vehicles without sacrificing safety, or can improve protection without making vehicles heavier.
Increasing sleep duration may help reduce cardiometabolic risk--or the risk of heart disease and metabolic disorders-- in individuals who do not get enough sleep, according to an analysis of all published studies on the topic.
System 91L is an area of tropical low pressure located in the Bay of Campeche. On June 3, when NASA-NOAA's Suomi NPP satellite passed the western Gulf of Mexico, it captured an image of the storm that showed its extensive reach.
Children can keep full visual perception - the ability to process and understand visual information - after brain surgery for severe epilepsy, according to a study funded by the National Eye Institute (NEI), part of the National Institutes of Health. While brain surgery can halt seizures, it carries significant risks, including an impairment in visual perception.
A Concordia biology professor is calling on ant experts to develop a set of common principles that influence the way the insects respond when their habitat undergoes severe disruption.
Scientists of Far Eastern Federal University (FEFU) in collaboration with colleagues from South Ural State University and the Chinese Academy of Sciences have developed an alternative method for numerical evaluation of the current induced local magnetization effect in ultrathin ruthenium-cobalt-ruthenium films with a wolfram layer added. That is another throw to fathom how to control spin orientation needed for the correct operation of spintronic electronics devices. A related article was published in Physical Review Applied.
Cancer-related inflammation impacts significantly on cancer development and progression. New research has observed in zebrafish, for the first time, that inflammatory cells use weak spots or micro-perforations in the extracellular matrix barrier layer to access skin cancer cells.
LAWRENCE -- A clutch of marine fossil specimens unearthed in northern Portugal that lived between 470 and 459 million years ago is filling a gap in understanding evolution during the Middle Ordovician period.
The discovery, explained in a new paper just published in The Science of Nature, details three fossils found in a new "Burgess Shale-type deposit." (The Burgess Shale is a deposit in Canada renowned among evolutionary biologists for excellent preservation of soft-bodied organisms that don't have a biomineralized exoskeleton.)
Canadian researchers have discovered a molecular indicator of a mechanism that drives cancer progression, giving doctors the possibility of using precision medicine, that is, choosing which patients will respond to a particular anticancer drug.
In a study published in Cancer Research, a team of biochemists at Université de Montreal found that a group of enzymes called SRC kinases chemically modify a tumour-suppressing protein called SOCS1.
