NASA Goddard: ‘A Field Guide To Black Holes’

If you’re looking to find some black holes, it’s always helpful to know exactly what you’re looking for!

To get started on your black hole hunt, first watch this handy video to learn the basics about these strange cosmic objects.

Science Podcast: Views Of Magnetars, When Human Brains Got Complex

Host Sarah Crespi talks with Contributing Correspondent Joshua Sokol about magnetars—highly magnetized neutron stars. A recent intense outburst of gamma rays from a nearby galaxy has given astronomers a whole new view on these mysterious magnetic monsters. 

Also on this week’s show, Christoph Zollikofer, a professor of anthropology at the University of Zurich, talks about the evolution of humanlike brains. His team’s work with brain-case fossils suggests the complex brains we carry around today were not present in the early hominins to leave Africa, but later developed in the cousins they left behind. 

Science Podcast: Museum Collections & Pandemics, Mice That Hallucinate

Podcast Producer Meagan Cantwell talks with Pamela Soltis, a professor and curator with the Florida Museum of Natural History at the University of Florida and the director of the University of Florida Biodiversity Institute, about how natural collections at museums can be a valuable resource for understanding future disease outbreaks.

Also on this week’s show, Katharina Schmack, a research associate at Cold Spring Harbor Laboratory, joins producer Joel Goldberg to talk about giving mice a quiz that makes them hallucinate. Observing the mice in this state helps researchers make connections between dopamine, hallucinations, and mental illness.

Covid-19 Podcast: What Are Vaccine Side Effects?

From a sore arm to anaphylaxis, a wide range of adverse events have been reported after people have received a COVID-19 vaccine. And yet it is unclear how many of these events are actually caused by the vaccine. In the vast majority of cases, reactions are mild and can be explained by the body’s own immune response.

But monitoring systems designed to track adverse events are catching much rarer but more serious events. Now scientists need to work out if they are causally liked to the vaccine, or are just statistical anomalies – and that is not an easy task.News: Why is it so hard to investigate the rare side effects of COVID vaccines?Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

Science Of Aging: Social Insects May Hold Secrets

Bees, termites, and ants can teach us a lot about cooperation, communication, and the skills that keep societies together. But these so-called social insects may also hold secrets that could reshape our understanding of human aging. Many social insects exhibit surprising aging characteristics that cause their life spans to shift depending on their roles.

Following the death of a queen Indian jumping ant, for example, workers fight for the right to transform into an egg-laying ant. Much is at stake: the life expectancy of an egg-layer is five times longer than that of a worker’s. Though fruit flies, mice, and nematodes currently dominate aging research, some scientists say social insects’ aging behaviors could help dissect aging mechanisms in humans. This video will take you deep into the catacombs—er, honeycombs—of insect aging.

Health: ‘Gut Microbiomes – Enabler Of Longer Lives’

Microbiomes are complex microbial ecosystems, and amongst those found in and on human body, gut microbiome is the most complex. It performs important functions, and is increasingly recognized as a key element influencing long-life health. Specific nutritional components, such as prebiotics and probiotics, can be used to shape healthy gut microbiome. Nestlé Research has made significant contributions in this field for over 30 years.
