Researchers in the department of Astrophysical Sciences at Princeton University, led by Dr. Stefansson, a former NASA Sagan Fellow, have discovered a new planet, LHS 3154b, which forces scientists to reassess traditional models of planet formation.

Have you ever wondered how planets are formed? 🪐.Check out @Vyshnavi_1812 's article featuring work done by a team of researchers at Princeton led by @gummiks to see how the discovery of a new planet challenges current theories of planet formation.

Despite not containing the virus itself, infected cells’ neighbors had viral proteins that disrupted their defenses. Infected cells send these proteins in packets called extracellular vesicles, preparing the way for viral spread.

Distant cells responded to alarm signals from infected cells by putting up their defenses, but surprisingly, the team found that cells that grew close to the infected cell actually became more susceptible to viral infection.

Led by post-doc Bokai Song and grad student Xinlei Sheng, the team used a clever combination of fluorescent tags to sort cells based on how close they had been to HCMV-infected cells. They then looked at the proteins in each cell population to measure their response.

How does a cell react when its neighbor becomes a virus-making zombie? 🧟🦠🧪 Is it any different from when it’s a cell “across town”? In their recent publication in Science Advances, the Cristea Lab in the Princeton Department of Molecular Biology decided to find out!.

Above all, the team’s research holds incredible promise for conservation and restoration moving forward, offering comprehensive mapping and actionable solutions to address one of the world’s most pressing issues.

There is good news, however: Zeng et al. identified the potential benefit of remedial measures. For example, enlarging and bolstering park networks across 1% of the earth’s total terrestrial area has the potential to save 1,191 species.

The team created a map of the land available to many threatened species, finding a stark correlation between species’ range size & extinction risk. And even if species’ ranges are mostly contained in parks, rollbacks on legal protections still pose a pervasive threat.

In a modern world where land-use change is common & legal protection for parks is often rolled back, Zeng et al. sought to determine where vulnerable species currently reside and when it would be appropriate to create new parks as opposed to strengthening existing ones.

The term “park” or “protected area” might bring to mind an idyllic safe haven for animals-but whether a park can truly protect species at risk of extinction is dependent on its legal protections, particularly in the context of land-use changes like farming or construction.

Riehl et al. speculate that these birds’ stake in the survival of one another’s offspring underlies this behavior. Ultimately, Riehl et al. show that unrelated individuals w/in a species can engage in intricate cooperative behavior - a major advance in behavioral ecology.

Incredibly, these birds use this alarm system to alert other greater anis that they share their communal nests with, even though genetic testing showed they were no more related to one another than they were to greater anis from a different nest.
