The facility suffered a still unexplained mishap last November during the launch of a Soyuz capsule carrying two Russians and one American to the orbiting station. Officials said a component called a maintenance or service cabin failed to move out from under the blast of exhaust from the ascending rocket.
For over 15 years, the EFRC program has provided a transformational research environment that has brought together the strengths of our National Laboratories and universities to accelerate discovery, develop innovative tools, and train the next generation of the American energy science workforce. The EFRCs will continue to play a vital role in bridging disciplines and institutions, advancing foundational science and strengthening America's leadership to push forward scientific frontiers critical for new energy technologies.
The rods are the central element of a novel seismic-responsive structural system that is designed to help the building snap back to its original shape in the event of a major earthquake. Their trick is an embedded cluster of taut cables made from a highly flexible compound called a shape-memory alloy that's capable of bending under tension-like the lateral shaking in a California earthquake-and then straightening out.
GEMINI leverages a computationally designed protein assembly as an intracellular memory device to record the history of individual cells. GEMINI grows predictably within live cells, capturing cellular events as tree-ring-like fluorescent patterns for imaging-based retrospective readout. Absolute chronological information of activity histories is attainable with hour-level accuracy.
If we told them to look at the face, they could usually manage it. But they were mostly looking at the hands. The Prakash children eventually learn to look at faces when spoken to - usually a few months after their surgeries. Their experiences reveal that seeing doesn't come naturally the moment a person is cured of blindness. Newly-sighted people must learn to see.
Researchers administered one of four doses of stem cells to 118 people between 70 and 85 years old, all of whom had frailty. In a timed walking test nine months after treatment, those who had received the highest dose could walk about 60 metres farther, on average, than they could before treatment.
According to Einstein's General Relativity, for every black hole that exists within the Universe, there are only three properties that go into it that matter in any way: the black hole's total mass, the black hole's net electric charge, and the black hole's intrinsic angular momentum, and that's it. It doesn't matter what type of matter went into the black hole in order to form it; all that matters is its mass, charge, and angular momentum.
It influenced my idea of what animals and natural history were, almost before I knew what real animals in the real world were like. For some researchers, themes in the Pokémon games mirror their everyday work. Spencer Monckton, a research scientist at the University of Guelph in Canada, who grew up playing the games and watching the TV series, says that collecting Pokémon is very much the same thing as what an entomologist does.
We found that life is more likely to survive an asteroid impact, so it's definitely still a real possibility that life on Earth could have come from Mars. Maybe we're Martians! The idea that life could have spread through the solar system or even the universe on rocks is known as the lithopanspermia hypothesis.
The article from the journal argues that the gut-autism axis is a house of cards built on lousy studies with inconsistent data. They assert that the studies are contradictory and that too much emphasis is placed on dubious mouse models. It is notoriously challenging to nail down microbial causes of disease—it is hard enough to simply identify a normal microbiome.
Both species are under threat. But while African savanna elephants are endangered, forest elephants are critically endangered. They're also highly elusive. Living in dense tropical rainforests in central Africa and parts of West Africa they're very hard to find and study.
The results showed that the squeaking sound is produced by wave-like patterns across the rubber surface, contacting and then releasing from the glass, allowing the sliding between the surfaces. The waves move across the interface between the two materials at a speed of nearly 300 kilometers per hour.
Although there are many amber stones containing a single creature, there are fewer that include two or more, as is the case with a pair of mosquitoes trapped in amber 130 million years ago which tell us that, back then, males also sucked blood. Even more extraordinary is when several organisms can be seen interacting, either eating the other, acting as a parasite, or cooperating.
Such sex 'distorters' have been discovered - and studied in great depth - in laboratory animals such as mice and flies, in which their effects can be detected through selective breeding. 'If you look, more often than not, you find them,' says Nitin Phadnis, an evolutionary geneticist at the University of Utah in Salt Lake City, who co-led the study.
Mini 3D 'organoids' are slowly phasing out animal testing in some areas of research. These laboratory-grown tissue structures can model human biology more accurately than traditional animal models, reducing the need for animal experimentation while providing more relevant data for drug development and disease research.
an electron within a molecule gets excited to a higher-energy state, the electron de-transitions back to the lower energy state, where it emits light of a very specific wavelength in the process. Then, pumped or injected energy re-excites an electron within that very same molecule back into that higher-energy state, over and over.
Artemis III aims to land astronauts near the lunar South Pole, relying on SpaceX's Starship-derived Human Landing System (HLS) - a vehicle that has yet to achieve orbit, let alone venture anywhere near the Moon. It's an extraordinarily ambitious undertaking, and one the ASAP report has formally classified as high risk.
We've always said that SuperAgers show that the aging brain can be biologically active, adaptable, flexible, but we didn't know why. This is biological proof that their brains are more plastic, and a real discovery that shows that neurogenesis of young neurons in the hippocampus may be a contributing factor.
Our new study suggests that the Apollo samples are biased to extremely rare events that lasted a few thousand years - but up to now, these have been interpreted as representing 0.5 billion years of lunar history. It now seems that a sampling bias prevented us from realizing how short and rare these strong magnetism events were.
In 1938 Blodgett's meticulous experiments with thin film coatings on solid surfaces lead to her most important breakthrough: nonreflecting glass. GE's public relations machine kicks into high gear. Blodgett becomes an overnight sensation in both the scientific community and the press, which dubs her discovery invisible glass. The assistant to the Nobel Prize winner, long invisible herself, takes center stage.
My first thought was whether a small leaf had somehow stuck to the outside of the window. But then I quickly realized that couldn't happen because we were in space. How could there possibly be a fallen leaf there? We could see very clearly the small cracks [with the microscope]. Several were relatively long, and one was shorter. We could also see that some of the cracks had penetrated through.
The fewer solicitations you have, the less time grant applicants have to figure out which of our pigeonholes they fit into. In the past, a solicitation might have been for an individual program, which means it's attached to an individual program officer and a specific dollar amount. Now, instead of going to one program officer's area, the NSF will use technology to better route applications to wherever within the agency they can best be reviewed.
Every black-and-white photograph of the layers of our planet's tectonic history is an act of time travel - it gets us closer to understanding the past and the future of Earth. The photos are proof that the world is ever changing, showing how vast plains of sedimentary materials shift and morph over thousands of centuries.
Tuning frictional behavior on the fly has been a long-standing engineering dream. This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.
Human breasts sit at an elevated temperature, protecting a newborn from hypothermia. What's more, the size and shape of the breast allows for broad contact surface - enhancing the heat transfer from mother to child. This could improve a newborn's chances of survival and provide an evolutionarily grounded explanation for the development of external breasts in humans.
