How rocket launches could threaten Australia's coastal wildlife
Space and rockets have been big news of late, from the successful Artemis 2 mission in April to the recent listing of SpaceX on the Nasdaq stock exchange.

Migratory birds may carry fewer parasites between islands than expected, DNA shows
A new study published in the Journal of Helminthology by researchers from the Estonian University of Life Sciences and the Swedish University of Agricultural Sciences, together with collaborators from Greenland and the Faroe Islands, has revealed surprisingly limited dispersal of Diplostomum parasites across North Atlantic islands. The findings challenge the common assumption that migratory birds readily transport parasites over large geographic distances.

Quantum vacuum could help break molecular bonds with less energy, simulations suggest
A team of researchers led by Felipe Herrera, a professor at the University of Santiago and a researcher at the Millennium Institute for Research in Optics (MIRO), has identified a quantum phenomenon that enables chemical bonds to be broken using significantly less energy than is normally required.

Opportunities across childhood best predict degrees, earnings for low-income youth
A new study led by a Boston College researcher has found that experiencing educational opportunities in all stages of childhood and adolescence is the best predictor of higher educational attainment and earnings for disadvantaged American youth, as opposed to the impact of learning access during any single phase.

Island life changed how Brazil's Noronha skink reproduces, but the lizard's strategy might be failing
Visitors to the Fernando de Noronha archipelago, located about 340 miles (545 kilometers) off the coast of Pernambuco in northeastern Brazil, soon notice a small lizard. Seemingly ubiquitous, it roams among rocks, trails and urbanized areas, approaching people and stealing food in plain sight when it can, and rarely flees.

Black women academics in my study said their main allies were white men: What this reveals
Universities have a role in challenging the status quo on issues such as gender, race, nationality and sexuality. But all too often, they replicate societal inequalities.

Saturn-ring-like laser emission from chiral polymeric microspheres
Controlling light within microscopic spaces is crucial for next-generation optical devices such as photonic integrated circuits and localized sensors. Microspheres formed of luminescent π-conjugated polymers act as optical resonators that confine and amplify light via whispering gallery modes (WGMs), and they are promising candidates for microscale organic lasers and photonic applications. However, conventional microsphere resonators are geometrically isotropic and emit isotropic light, making directional control of emissions challenging.

Galaxy mergers aren't always obvious
The galaxy Centaurus A is about 11 million light-years away and is the fifth-brightest galaxy in the sky. Because it's so bright, it's been studied extensively by amateur and professional astronomers alike. Also called NGC 5128, it's a starburst galaxy, meaning it's forming stars at a rapid rate.

Weak connection: Why influencers sometimes fail to influence
Conventional wisdom holds that targeting the best-connected individuals in a social network is an effective way to nudge a wider group of people to change their behavior. For example, public health officials launching a campaign to improve nutrition might target a community's leaders on the assumption that they wield the most influence. The effectiveness of this approach, however, depends on the structure of the social network, a new Yale study finds.
