InSight mission will end science operations in July because of dust on its solar panels
In a major advance for rational drug design, a Texas A&M AgriLife team has described several protein structures of a crucial player in cellular processes. The advance could bring new ideas for treatments of diseases such as Alzheimer's, AIDS, cancer and others.
Plasmids have extensive use in basic and applied biology. These small, circular DNA molecules are used by scientists to introduce new genes into a target organism. Well known for their applications in the production of therapeutic proteins like insulin, plasmids are broadly used in the large-scale production of many bioproducts.
Dusty solar panels and darker skies are expected to bring the Mars lander mission to a close around the end of this year.
Researchers have developed PlasmidMaker, a versatile automated platform for plasmid design & construction. These circular DNA molecules are used by scientists to introduce new genes into a target organism, and have extensive use in basic and applied biology. In particular, they have applications in the large-scale production of bioproducts.
A theoretical framework shows how to increase the odds of identifying cancer-causing mutations before tumors take hold. Researchers demonstrate that only a few energetically favorable pathways are likely to lead to cancer.

This newly revised NASA Hubble Space Telescope image of the Hickson Compact Group 31 (HCG 31) of galaxies highlights streams of star-formation as four dwarf galaxies interact. The bright, distorted clump of young blue-white stars (top-right of center) is NGC 1741. Although it appears to be a single galaxy, NGC 1741 is actually a pair of colliding dwarf galaxies. Another dwarf, cigar-shaped galaxy...
In the Temple of Khnum at Esna, Upper Egypt, German and Egyptian researchers have uncovered a series of vibrantly-colored ceiling frescoes. The relief images in the central section of the ceiling, Professor Christian Leitz from the University of Tübingen reports, make up a total of 46 depictions of the Upper-Egyptian vulture goddess Nekhbet and the Lower-Egyptian serpent goddess Wadjet. Both are...
Vibrant coral reefs teeming with marine life are diminishing throughout the Caribbean as global temperatures rise. Coral reefs are habitats that support the seafood industry, are barriers for coastal communities from storms, flooding and sea level rise, and are attractions for tourism. Their net economic value worldwide is estimated to be tens of billions of dollars. However, if atmospheric and...
A new research paper published in Aging Volume 14, Issue 9, is titled "Single-cell transcriptomics reveals age-resistant maintenance of cell identities, stem cell compartments and differentiation trajectories in long-lived naked mole-rats skin."
Compact and lightweight metasurfaces—which use specifically designed and patterned nanostructures on a flat surface to focus, shape and control light—are a promising technology for wearable applications, especially virtual and augmented reality systems. Today, research teams painstakingly design the specific pattern of nanostructures on the surface to achieve the desired function of the lens,...
Inotiv disputes findings of undercover investigation by Humane Society of the United States
Climate change and trampling threaten “biocrusts,” allowing wind to attack dry soils
Zoning laws, adopted by thousands of local governments across the country, dictate much of what can be built in the United States. Zoning codes have major ramifications for businesses, housing, and quality of life but can be very difficult for non-experts to understand.
Researchers have developed a new method for designing large-scale metasurfaces that uses techniques of machine intelligence to generate designs automatically. The method will enable new metasurface designs that can make an impact on virtual or augmented reality, self-driving cars, and machine vision for embarked systems and satellites.
Taking multiple prescription drugs and supplements can be fraught with risk, a new study suggests -- but it's hard for many people to part with their medications.
Researchers who jumped into the field from distant disciplines published lower impact work, study finds
The House Intelligence Committee’s Counterterrorism, Counterintelligence, and Counterproliferation subcommittee would like to make one thing very clear: They did not spend 90 minutes this morning conducting public hearings into the existence of UFOs. Yes, they were discussing unidentified objects, and yes those objects were seen to be flying, but the term for them today is...
Early animals formed complex ecological communities more than 550 million years ago, setting the evolutionary stage for the Cambrian explosion, according to a new study.
A comparison of four COVID-19 vaccinations shows that messenger RNA (mRNA) vaccines -- Pfizer-BioNTech and Moderna -- perform better against the World Health Organization's variants of concern (VOCs) than viral vector vaccines -- AstraZeneca and J&J/Janssen. Although they all effectively prevent severe disease by VOCs, the research suggests that people receiving a viral vector vaccine are more...
Different types of brain damage caused by a concussion may lead to similar symptoms in children, according to new research. A new way of studying concussions could help develop future treatments.
Researchers have discovered that Type I interferon (IFN) plays a key role in helping the immune system effectively target viruses, while stopping white blood cells from 'going rogue' and attacking the body's own organs. This opens the way to potential new treatments that can save many lives.
Older breast cancer survivors with cardiometabolic risk factors who restricted food intake to eight hours during the weekday, followed by 16 hours of fasting, lowered their risk of cardiovascular disease (CVD) after a few weeks, according to a new research letter.
The waters rose overnight and by morning formed a shallow pond over the grassy field covering a cemetery in Jamestown, one of the founding sites of the American nation.
