NASA conducted a test firing of the engines for its giant Space Launch System (SLS) lunar rocket on Saturday but they shut down earlier than planned, the space agency said.
The world is falling short of promises made under the Paris climate deal to help the most vulnerable nations deal with the increasingly devastating impacts of climate change, according to the United Nations.
Some beetles go to great—and disgusting—lengths for their children.
Egypt's former antiquities minister and noted archaeologist Zahi Hawass on Sunday revealed details of an ancient funerary temple in a vast necropolis south of Cairo.

Mount Semeru, the highest volcano on Indonesia's most densely populated island of Java, spewed hot clouds as far away as 4.5 kilometers (nearly 3 miles) on Saturday.
One of the world's longest-running wildlife field studies has fallen prey to the coronavirus pandemic.
The coronavirus pandemic has slowed global migration by nearly 30 percent, with around two million fewer people than predicted migrating between 2019 and 2020, according to a UN report released on Friday.
Australian firefighters said they expect to battle an out-of-control bushfire well into the night on Saturday, as the blaze threatens lives and homes in the west coast city of Perth.

A group of more than 60 scientists have provided recommendations to improve the Indian Ocean Observing System (IndOOS), a basin-wide monitoring system to better understand the impacts of human-caused climate change in a region that has been warming faster than any other ocean.
In groundbreaking materials research, a team led by University of Minnesota Professor K. Andre Mkhoyan has made a discovery that blends the best of two sought-after qualities for touchscreens and smart windows—transparency and conductivity.
A trio of papers provide new insight into the composition and evolution of the surface of Venus, hidden beneath its caustic, high temperature atmosphere. Utilizing imaging from orbit using multiple wavelengths—six-band spectroscopy proposed as part of the VERITAS and EnVision missions—scientists can map the iron content of the Venusian surface and construct the first-ever geologic map.
The Milky Way houses 8,292 recently discovered stellar streams—all named Theia. But Theia 456 is special.
A team of scientists from Osaka University, the University of Queensland and the National University of Singapore's Faculty of Engineering used tiny nanodiamonds coated with a heat-releasing polymer to probe the thermal properties of cells. When irradiated with light from a laser, the sensors acted both as heaters and thermometers, allowing the thermal conductivity of the interior of a cell to be...
Did you know that in microgravity we are preparing one of the most promising fuels for the future?
While losses vary by sector, by region and by industry, data and information from this report may help businesses and communities assess losses and inform long-term recovery and resilience strategies.
Scientists studying the body's natural defenses against bacterial infection have identified a nutrient—taurine—that helps the gut recall prior infections and kill invading bacteria, such as Klebsiella pneumoniae (Kpn). The finding, published in the journal Cell by scientists from five institutes of the National Institutes of Health, could aid efforts seeking alternatives to antibiotics.
A refractive index of zero induces a wave vector with zero amplitude and undefined direction. Therefore, light propagating inside a zero-index medium does not accumulate any spatial phase advance, resulting in perfect spatial coherence. Such coherence brings several potential applications, including arbitrarily shaped waveguides, phase-mismatch-free nonlinear propagation, large-area single-mode...
Plant pathologists working at universities across 26 corn-producing states in the United States and in Ontario, Canada, compiled data about annual corn reductions caused by diseases. Estimated loss from each disease varied greatly by region.
Like a person breaking up a cat fight, the role of catalysts in a chemical reaction is to hurry up the process—and come out of it intact. And, just as not every house in a neighborhood has someone willing to intervene in such a battle, not every part of a catalyst participates in the reaction. But what if one could convince the unengaged parts of a catalyst to get involved? Chemical reactions...
The Gulf of Mexico holds huge untapped offshore oil deposits that could help power the U.S. for decades.
A lonely rhinoceros at a Bangladesh zoo is looking for new love after losing her partner seven years ago, but pandemic travel restrictions are hampering her keeper's attempts to play matchmaker.
For most people, the word "vampire" brings to mind Dracula or perhaps slayers such as Blade or Buffy; or maybe even the vampire bats of South America. Few will think of a small and rather lovely bird—the finch.
Millions of birds travel between their breeding and wintering grounds during spring and autumn migration, creating one of the greatest spectacles of the natural world. These journeys often span incredible distances. For example, the Blackpoll Warbler, which weighs less than half an ounce, may travel up to 1,500 miles between its nesting grounds in Canada and its wintering grounds in the Caribbean...
