On July 4th 2016, NASA announced that the spacecraft Juno arrived at Jupiter after traveling two billion miles over five years. Juno was designed to investigate the origin of Jupiter, our solar system’s largest planet.

As we discussed last time, bacteria that infect the human body face a major challenge: iron, which is essential for bacterial growth, is hard to obtain from human tissues. Many pathogenic bacteria solve this problem by deploying “stealth siderophores,” which steal iron from human iron-binding proteins while evading our defenses. In the battle between humans and pathogenic bacteria, our best weapons, antibiotics, are being weakened by widespread resistance. Is there a way to use bacteria’s need for iron against them?

Many remember the boisterous, muscle-bound, tattooed sailor Popeye and the thin-as-a-rail Olive Oyl from Saturday morning cartoons. In times of need, such as when his rival Bluto stole Olive Oyl for the 50th time, Popeye would squeeze open a tin can of spinach. Eating the spinach, sometimes miraculously through his corn-cob pipe, gave Popeye that extra boost of energy needed to escape his bonds and rescue his lady-friend. What was so special about spinach that gave Popeye his superpower?

Zebrafish may not look impressive, but they can do something that no human can: regenerate large portions of organs that are damaged or lost. These fish, each about as long as your pinky finger, are able to regrow amputated fins, repair lesioned brains, and mend damaged eyes, spinal cords, and hearts. This remarkable ability to heal has fascinated scientists for some time, and in recent years, large strides have been made towards translating this regenerative ability to humans.

If you haven’t been living under a rock for the last five years, you have definitely come across headlines to the tune of “Researchers Find Gene for X”, where X can be anything from happiness, to political affiliation, to your preference for cilantro. There are quite a few people who respond to these studies with “but surely that’s not genetic!” I work on the genetics of psychiatric disorders and have fielded this question from most people with whom I discuss my research: “Isn’t something like depression just caused by things that happen to you or your upbringing? Why do we place the blame on genetics instead?”

We live in a world of science and technology. Biomedical research helps improve our lives everyday by providing us with vital information about everything from hygiene to Alzheimer’s disease. Computers provide us with access to wealth of information on any subject in an instant and expedite many of our daily activities. Often these two worlds overlap and computers are also used to provide scientists with information about our own health and survival to facilitate biomedical research.

The team at MiSciWriters certainly finds cephalopods fascinating, and we aren’t alone. Last year, the octopus (Octopus bimaculoides) was added to the growing list of organisms whose genome sequence is known.
Octopuses belong to a class of organisms called cephalopods, which literally means ‘head-feet’ (members of the cephalopod family have a head and tentacles or arms). These tentacles enable the creatures to do some very clever maneuvering, such as escaping their aquariums to eat crabs outside their tanks. It’s no surprise then that these are the most intelligent amongst invertebrates and now new information about the octopus genome can tell us more about these fascinating creatures.

Whether you have heard about it or not, antibiotic resistance is a growing threat that affects us all.
For generations, we have benefited from antibiotics to fight bacterial infections that would otherwise threaten our lives. Unfortunately, the effectiveness of antibiotics is increasingly at risk. Bacterial infections resistant to antibiotics already have already taken a significant toll and the severity of the problem is only growing. In the United States, it already costs us over 23,000 lives and an estimated $55 billion each year.
As we head into a new school year and the colder winter months when illness risks seem to rise, the timing couldn’t be better to remind you that everyone (yes, you!) plays a role in combating this growing problem of antibiotic resistance. But first we need to understand the basics of this problem, including the three major factors at play.

Why haven’t we cured cancer? Physicians have known about cancer for over 5000 years, and the United States spends nearly $5 billion per year on cancer research. But there’s still no cure. Also, where is our clean, renewable energy? We can’t even catch half the energy in sunlight, and solar panels don’t come cheap! Why don’t we have a moon colony yet or a male birth control pill?
In the U.S., science funding comes from many sources, including the taxpayers. As an example, half a percent of the federal budget goes to fund NASA, before considering all of the money that goes to the National Science Foundation (NSF) or the National Institutes of Health and other federal science organizations. It is reasonable that publicly-funded science should provide some benefit for the public, but it seems like there’s a lot of scientific research out there that’s not giving us the technologies and discoveries we want and need. So why do we throw money at projects that don’t seem to deliver?

In “Virus vs Bacteria: Mortal combat” we learned that bacteriophage (phage) are a group of viruses that literally prey on bacteria and archaea. Phage fill a predatory role in their native ecosystems, helping to keep prey populations in check, in turn preventing exhaustion of available resources. We also explored in “Virus vs Bacteria: Enemy of my enemy” how humans can exploit these bacterial predators to be useful in a number of ways. But there’s quite a bit more to phage than meets the eye. New research is beginning to show us additional ecological impacts phage have on their environments—ones that can play a role in challenges humans face such as climate change and antibiotic resistance.
