If you’ve driven the mostly flat stretch of I-25 in Colorado from Pueblo to Trinidad, you’ve seen them: the Spanish Peaks, twin mountains that soar into the sky out of nowhere, reaching altitudes of 13,628 and 12,701 feet above sea level. In a new study, geologists from the University of Colorado Boulder have laid out a timeline for the emergence of these majestic but isolated mountains. The team’s findings could bring scientists closer to answering one of the most enduring puzzles in Colorado geology: What made ...

Looking deeply into space and time, two teams using NASA’s James Webb Space Telescope have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old. Initially detected with NASA’s Hubble Space Telescope, this galaxy — one of the youngest and most distant ever observed  — is so bright that it is challenging scientists to understand why. Now, GN-z11 is giving up some of its secrets. Vigorous Black Hole Is Most Distant Ever Found A team studying ...

UNIVERSITY PARK, Pa. — Fat tissue holds the key to 3D printing layered living skin and potentially hair follicles, according to researchers who recently harnessed fat cells and supporting structures from clinically procured human tissue to precisely correct injuries in rats. The advancement could have implications for reconstructive facial surgery and even hair growth treatments for humans.  The team’s findings published today (March 1) in Bioactive Materials. The U.S. Patent and Trademark ...

Researchers at Cima Universidad de Navarra have discovered that a ribonucleic acid that does not contain information to make proteins (long non-coding RNA) plays a crucial role in signalling and repairing errors in DNA replication during cell division. This finding could lead to the development of new anti-tumour therapies. Scientists have identified an RNA that they named 'lncREST' (long non-coding RNA REplication STress) and uncovered its role in triggering an effective response to the stress induced by rapid cell division. "LncREST localises ...

FOR IMMEDIATE RELEASE   People with cancer have different amounts of a type of repetitive DNA — called Alu elements — than people without cancer. Now, machine learning can measure that from a blood draw. Researchers at the Johns Hopkins Kimmel Cancer Center have used this finding to improve a test that detects cancer early, validating and reproducing the results by starting with a sample size tenfold larger than typical of such types of studies. The research was published Jan. 24 in the journal Science Translational Medicine. Alu ...

As it trundles around an ancient lakebed on Mars, NASA’s Perseverance rover is assembling a one-of-a-kind rock collection. The car-sized explorer is methodically drilling into the Red Planet’s surface and pulling out cores of bedrock that it’s storing in sturdy titanium tubes. Scientists hope to one day return the tubes to Earth and analyze their contents for traces of embedded microbial life.  Since it touched down on the surface of Mars in 2021, the rover has filled 20 of its 43 tubes with cores of bedrock. Now, MIT geologists have remotely determined a crucial property of the rocks collected to date, which will help scientists answer key questions about the planet’s ...

URBANA, Ill. — When broiler chickens are busy fighting the parasitic infection coccidiosis, they can’t absorb nutrients efficiently or put energy toward growth. With consumer sentiment pitted against antimicrobials and other drugs, producers still have some options to ensure optimal growth during inevitable outbreaks. New research from the University of Illinois Urbana-Champaign suggests diet changes might help.  “Vaccines and anticoccidials are the traditional ways to prevent this disease. Nutrition can't replace all of the pharmaceuticals, but it can be supportive in providing care,” said senior study author Ryan Dilger, ...

March 4, 2024- New York City neighborhoods with disrupted community connections, due to traffic, roads, and transport infrastructure, are experiencing an increase in traffic collisions. This increase is seen both in total collisions and for those in which pedestrians or cyclists are injured or killed, according to a new study from Columbia University Mailman School of Public Health. The findings are reported in the journal Environment International. “Despite recent remarkable progress, road safety remains an urgent urban issue in New York and other U.S. cities. It is important to understand how the spatial configuration of the city enhances ...

EDMONTON — A University of Alberta research team has uncovered a new class of drugs with the potential to prevent or treat infections in a future viral outbreak. In the paper, published this week in Nature, the team reports that SARS-CoV-2 — the virus that causes COVID-19 — activates a pathway in cells that stops the production of peroxisomes and interferon, key parts of the normal immune response. The team successfully tested a new class of antiviral drugs that stimulate interferon production to reverse that effect. Tom ...

Switzerland plans to reduce its net carbon emissions to zero by no later than 2050. To achieve this, it will need to drastically reduce its greenhouse gas emissions. In its climate strategy, the Swiss government acknowledges that some of these emissions, particularly in agriculture and industry, are difficult or impossible to avoid. Swiss climate policy therefore envisages actively removing 5 million tonnes of CO2 from the air and permanently storing it underground. By way of comparison, the Intergovernmental ...

(Santa Barbara, Calif.) — You’d probably walk past a chiton without even seeing it. These creatures often look like nothing more than another speck of seaweed on the crusty intertidal rocks. But it sees you. At least, if it’s one of the species with eyes dotting its platemail shell. A team of scientists — led by Rebecca Varney at UC Santa Barbara’s Department of Ecology, Evolution, and Marine Biology (EEMB) — discovered that some of these tough mollusks sport the most recently evolved eyes with a lens. What’s more, the ...

CLEVELAND—Oral cancers and precancerous mouth lesions are considered especially difficult to diagnose early and accurately. For one, biopsies are expensive, invasive, stressful for the patient and can lead to complications. They’re also not feasible if repeated screenings of the same lesion are required. But a team of researchers, led by a clinician scientist at the Case Western Reserve University School of Dental Medicine, has discovered a noninvasive, low-cost test to detect oral cancer, monitor precancerous lesions and determine when a biopsy is warranted. Their findings, published ...

A  New Jersey Gun Violence Research Center study is the first to provide nationally representative data on gun use, storage and violence within Black and American Indian/Alaskan Native (AIAN) families. Both Black and native communities have seen increasingly elevated rates of gun violence victimization, including homicide and suicide, according to the Centers for Disease Control and Prevention. In recent years, minorities have become more represented among new firearm owners. Despite this, research on firearm access, storage and use has focused on samples of white adults. This prevents understanding the access Black and native individuals have to firearms, whether they are stored ...

A new cellphone app developed by physician-scientists at UPMC and the University of Pittsburgh, which uses artificial intelligence (AI) to accurately diagnose ear infections, or acute otitis media (AOM), could help decrease unnecessary antibiotic use in young children, according to new research published today in JAMA Pediatrics. AOM is one of the most common childhood infections for which antibiotics are prescribed but can be difficult to discern from other ear conditions without intensive training. The new AI tool, which makes a diagnosis by assessing ...

About The Study: This study found a negative association between screen time and measures of parent-child talk when children are 12 to 36 months of age. For every additional minute of screen time, children heard fewer adult words, spoke fewer vocalizations, and engaged in fewer back-and-forth interactions. Interventions aiming to promote early use of language should include support to manage screen time.  Authors: Mary E. Brushe, Ph.D., of the University of Western Australia in Adelaide, South Australia, Australia, is the corresponding author.

About The Study: In this nationally representative survey study of 3,542 American Indian or Alaska Native and Black U.S. adults, a substantial percentage of both groups reported living in homes with firearms, storing firearms loaded and unlocked, frequently carrying firearms outside the home, and having been exposed directly and indirectly to gun violence. These findings underscore the need for nuanced public health campaigns and policies and highlight challenges for law enforcement in contexts of racial disparities ...

About The Study: The findings of this study of 2,943 counties suggest that medical debt is associated with worse health status, more premature deaths, and higher mortality rates at the county level in the U.S. Therefore, policies increasing access to affordable health care, such as expanding health insurance coverage, may improve population health.  Authors: Xuesong Han, Ph.D., of the American Cancer Society in Atlanta, is the corresponding author.  To access the embargoed ...

An inexpensive, cavity-fighting liquid called silver diamine fluoride (SDF) works as well as dental sealants to keep tooth decay at bay in a school cavity prevention and treatment program, according to a new study by researchers at NYU College of Dentistry.    The study, which followed more than 4,000 elementary school students for four years and is published in JAMA Pediatrics, shows that SDF is an effective alternative to sealants, and can increase access to dental care while reducing costs.   Dental cavities are the most prevalent ...

Testing of illicit drugs bought online found 35% were not what they said they were, highlighting the urgent need for more local drug testing facilities in Australia to prevent harm and overdose.   The RMIT-led study analysed 103 illicit drug samples sourced from the now-defunct dark web forum Test4Pay in collaboration with the Australian National University, UNSW Sydney and Canadian testing facility Get Your Drugs Tested.  While 65% of samples contained only the advertised substance, the study found 14% of samples had a mixture ...

In a discovery that opens the door to a less invasive way of treating some serious disorders before birth, UC San Francisco scientists have found that delivering medicine through amniotic fluid is as effective as delivering it to the fetal brain via cerebrospinal fluid. The experiment was done in mice with a genetic disorder called Angelman syndrome.     Treating genetic diseases like Angelman in utero could prevent serious symptoms that begin while the fetus is still developing. It’s also easier to access neurons in the fetal brain because the blood-brain barrier that normally acts as a filter ...

Inspired by amphibians such as the wood frog, investigators designed and synthesized a new type of camouflage skin involving one-dimensional photonic crystal structures assembled in three-dimensional flexible gels. As described in Advanced Optical Materials, the camouflage skin can quickly recognize and match the background by modulating the optical signals of external stimuli. It demonstrated excellent mechanical performance, self-adaptive camouflage capabilities in response to complex surroundings, and long-term stability in real-world living environments. Bright structural color and mechanical flexibility were maintained even at temperatures as low as -80℃. The advance ...

The quantum systems employed in quantum technologies, for example single atoms, are also very sensitive: any interaction with the environment can induce changes in the quantum system, leading to errors. However, this remarkable sensitivity of quantum systems to environmental factors actually represents a unique advantage. This sensitivity enables quantum sensors to surpass conventional sensors in precision, for example when measuring magnetic or gravitational fields. Noise cancellation using correlation spectroscopy The delicate quantum properties needed for sensing can be covered up ...
