LSU Health contributes to research suggesting late-onset retinal degeneration mechanism and potential Rx

A study led by LSU Health found how late-onset retinal degeneration develops and identified a surprising potential therapeutic, metformin. The research suggests that an enzyme called AMPK activates the protein CTRP5 to regulate fatty acid metabolism and energy stability.

Dinosaurs’ last spring: Study pinpoints timing of Chicxulub asteroid impact

A groundbreaking study confirms the timing of the Chicxulub asteroid impact, which occurred during the spring-summer growth phase, leading to the extinction of dinosaurs and 75% of life on Earth. The research team used multiple lines of evidence, including fossil pollen, index fossils, and radiometric dating, to pinpoint the exact time...

Burrowing snakes have far worse eyesight than their ancestors

Scientists found that seven genes associated with bright-light vision are absent in burrowing snakes, demonstrating extensive vision gene loss over millions of years. This challenges the hypothesis that all modern snakes evolved from extreme burrowers, suggesting a different evolutionary path for these subterranean snakes.

Previously unrecorded Chilean tsunami identified

A large earthquake off the coast of south-central Chile in 1737 may have caused a substantial tsunami that was absent from historical records. Researchers analyzed sediments and found evidence of widespread sandy layers, dating to the same time as the earthquake, similar to deposits made by tsunami waves in other areas.

Nature or nurture: How does an animal get its microbiome?

Researchers have found that sharks acquire their microbiome through three methods: the mother passing on microbes to her offspring via egg case, social interactions with other sharks, and recruiting microbes from their environment. This study provides new insights into the development of animal microbiomes and their importance in under...

Novel chemical design makes hard crystals stretchy

Researchers have designed porous, carbon-based crystals that can stretch to more than twice their length, making them suitable for nanofiltration and pollutant removal. By adding 'soft joints' into the crystal's scaffold, they can be disrupted by specific chemicals, causing the crystal to expand and contract rapidly.

New vaccine ingredient shows promise

Scientists at La Jolla Institute for Immunology and MIT have discovered a new adjuvant called SMNP, which combines saponin and TLR agonist to boost the protective power of vaccines. The study found that SMNP triggers a strong immune response in mice, promoting lymphatic drainage and activating multiple parts of the immune system.

High-speed holography of cells spots physical beacons of disease

Researchers at Duke University developed a holographic system that can image and analyze tens of thousands of cells per minute to spot signs of disease. The technique distinguished between healthy samples and cancerous or pre-cancerous cells with nearly 100% accuracy, using just four basic cellular physical parameters.

Fast-tracked stroke drug for humans shows promise, in mice, that it might also prove a powerful tool against dementia

A new study published in the Journal of Experimental Medicine showed that a fast-tracked stroke drug, 3K3A-APC, protected mice from injury to the brain's white matter, a leading cause of dementia. The drug may also be effective in slowing down progression of cognitive impairment.

Sugar could help repair artificial human joints

Researchers at Durham University have developed a sugar-containing polymer coating that can repair damaged artificial joint implants by mimicking the way cartilage works to lubricate human joints. The coating uses water to create a slippery surface, protecting the surfaces from wear and tear.

Researchers investigate link between bilingualism and false memories

A study published in Frontiers in Psychology found that false information in both native and second languages equally contribute to the formation of false memories. The researchers used an online experiment with participants speaking Russian and English to assess the influence of misinformation and source misattribution on memory recall.

New method gives rapid, objective insight into how cells are changed by disease

A new 'image analysis pipeline' called TDAExplore gives scientists rapid insight into how cells are changed by disease, using a combination of microscopy, topology, and artificial intelligence. This approach can provide objective information on cell changes, such as the movement of proteins like actin, even with limited training data.

New technique improves conversion of carbon dioxide into liquid fuels

Researchers at Lawrence Berkeley National Laboratory have developed a new approach to modify the surface of copper catalysts, improving the conversion of carbon dioxide into useful fuels. The technique involves coating the copper with thin films of ionomers, which steer the reaction towards generating carbon-rich products.

In a cross-adoption experiment researchers at Tel Aviv University found that adopted baby fruit bats behave like their adoptive mothers

Researchers at Tel Aviv University conducted a cross-adoption experiment with fruit bat pups to determine whether boldness is genetic or learned. The findings indicate that the pups behave like their adoptive mothers, not biological mothers, suggesting that boldness is an acquired trait passed on through mother's milk.
