WASHINGTON - A U.S. Naval Research Laboratory-built camera mounted on the NASA Parker Solar Probe revealed an asteroid dust trail that has eluded astronomers for decades.
Karl Battams, a computational scientist in NRL's Space Science Division, discussed the results from the camera called Wide-Field Imager for Solar Probe (WISPR) on Dec. 11 during a NASA press conference.
WISPR enabled researchers to identify the dust cloud trailing the orbit of the asteroid 3200 Phaethon.
The process of building a tiny cube has revealed some of the fundamental mysteries of how molecules bind together in natural environments. Researchers hope to apply this knowledge to future projects designing complex structures that can mimic life.
When two molecules surrounded by water move towards each other, part of their initial attraction is sometimes due to the chemical force to repel water -- the hydrophobic effect.
Once the molecules are near each other, but not yet formally bound, a much weaker force becomes important -- the dispersion force.
More than one hundred and fifty years have passed since the publication of James Clerk Maxwell's "A Dynamical Theory of the Electromagnetic Field" (1865). What would our lives be without this publication? It is difficult to imagine, as this treatise revolutionized our fundamental understanding of electric fields, magnetic fields, and light.
Uniting three different parameters in single cells taken from mouse embryos reveals more about how foundational cell identities are established in early development
The first single-cell multi-omics analysis of gastrulation allows researchers to connect gene expression, DNA methylation and chromatin accessibility to understand the role of the epigenome in regulating cell fate decisions in early development.
An analysis of sediment carried by glaciers in both South America and East Africa indicates that tropical glaciers not just in South America but across the tropics began to melt earlier than expected at the end of the Last Glacial Maximum (26,000-19,000 years ago), before atmospheric carbon dioxide levels began to rise. The study's authors suggest that the early melting may have been triggered by rising temperatures at the North and South Poles, which reduced a heat-driven atmospheric circulation cycle that in turn slowed the movement of heat out of the tropics.
CORVALLIS, Ore. - An international team co-led by an Oregon State University chemistry researcher has uncovered a better way to scrub carbon dioxide from smokestack emissions, which could be a key to mitigating global climate change.
Published today in Nature, the findings are important because atmospheric CO2 has increased 40 percent since the dawn of the industrial age, contributing heavily to a warming planet.
The immune system establishes "forward operating bases", or lymph node-like structures, inside the tumors of some patients with kidney and other urologic cancers, researchers at Winship Cancer Institute of Emory University have discovered.
Berkeley -- If you use a vacuum-insulated thermos to help keep your coffee hot, you may know it's a good insulator because heat energy has a hard time moving through empty space. Vibrations of atoms or molecules, which carry thermal energy, simply can't travel if there are no atoms or molecules around.
But a new study by researchers at the University of California, Berkeley, shows how the weirdness of quantum mechanics can turn even this basic tenet of classical physics on its head.
According to a new study led by a team from The University of New Mexico, centuries-old laws about the behavior of gas mixtures do not apply in the presence of shock waves.
This finding could have potential impact on everything that involves mixtures of gases exposed to a shock wave, for example, during combustion in an engine. This is also relevant for conventional and nuclear explosions, supersonic jets, gas-cooled nuclear reactor plants and inertially-confined fusion.
In the last decade, scientists have made tremendous progress in understanding that groups of bacteria and viruses that naturally coexist throughout the human body play an important role in some vital functions like digestion, metabolism and even fighting off diseases. But understanding just how they do it remains a question.
You're on a diet, but the aroma of popcorn in the movie theater lobby triggers a seemingly irresistible craving.
Within seconds, you've ordered a tub of the stuff and have eaten several handfuls.
Impulsivity, or responding without thinking about the consequences of an action, has been linked to excessive food intake, binge eating, weight gain and obesity, along with several psychiatric disorders including drug addiction and excessive gambling.
Researchers in Korea have found an effective and inexpensive strategy to transform solar cells from opaque to transparent. Existing transparent solar cells tend to have a reddish hue and lower efficiency, but by punching holes that are around 100 μm in diameter (comparable in size to a human hair) on crystalline silicon wafers, it allows light through without coloring. The holes are then strategically spaced, so the human eye is unable to "see" the pattern. The work appears December 11 in the journal Joule.
The United States faces a crisis in providing complex care for high-need, high-cost individuals--people who often suffer economic, mental and physical challenges.
In 2014, Jefferson launched a pilot curriculum to build interdisciplinary teams to reach out to high-need patients and attempt to find low-cost, high-touch ways to reduce their recurrent difficulties. The results of the Jefferson-based pilot appear Dec. 10 in a new publication of the New England Journal of Medicine, NEJM Catalyst Innovations in Care Delivery.
Phase III clinical trial results reported today in the New England Journal of Medicine and presented concurrently at the San Antonio Breast Cancer Symposium (SABCS) 2019 show the combination of the investigational drug tucatinib with standard of care treatment including the drugs trastuzumab and capecitabine nearly tripled one-year progression-free survival (33 percent vs. 12 percent), and nearly doubled the two-year overall survivor (45 percent vs. 27 percent) in women with HER2+ metastatic breast cancer.
The microbial community populating the human body plays an important role in health and disease, but with few exceptions, how individual microbial species affect health and disease states remains poorly understood. A new study by Princeton researcher Mohamed Donia and colleagues, which appeared in the journal Science on December 13, 2019, gives scientists new tools to explore and understand the human microbiome.
