Study determines the original orientations of rocks drilled on Mars
2024-03-04
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 ...

Illinois study: Supporting disease-challenged broiler chickens through nutrition

Illinois study: Supporting disease-challenged broiler chickens through nutrition
2024-03-04
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, ...

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 ...

Cost of direct air carbon capture to remain higher than hoped

2024-03-04
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 ...

Unraveling the mystery of chiton visual systems

Unraveling the mystery of chiton visual systems
2024-03-04
(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.

Case Western Reserve University-led research team discovers new method to test for oral cancer
2024-03-04
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 ...
