The world is going bananas! What? Bananas could die out from one disease? Say it ain’t so!
Fifty years since Apollo 11 first brought humankind to the Moon? No, it doesn’t seem like yesterday. It’s been way too long since we’ve left the comfort and safety of Earth orbit. Let’s go back to the Moon and beyond!
On This Week’s Show
- A recent visit to an asteroid
- Why catching a cold may not be such a bad thing after all
- And a not-so-recent visit to the moon
Science News with Chris MacAlister and JD Goodwin
Hayabusa-2: Japanese spacecraft makes final touchdown on asteroid
- It was only a few years ago that we were getting so excited by NASA’s Rosetta mission which orbited a comet, and its Philae lander which (kind of) successfully landed on it.
- As if this isn’t impressive enough, Haybusba-2 is basically showboating now because it’s not just gone down to the asteroid once, it’s now done it twice!
- On its first landing (in February) it collected some surface material; and this was pretty much the best that could be hoped for since the asteroid turned out to be much rockier than anyone had thought back when they were planning the mission.
- The people at JAXA know how to deal with stubborn space rock. In April, the spacecraft dropped a two-kilogram copper cylinder from about 500 meters above the surface to blast an artificial crater about 10 meters wide and 2 meters deep into its surface.
- This operation released material from deep within the asteroid. The team back on Earth watched where this debris settled and then sent Hayabusa down to pick some up.
- Hayabusa-2 will leave Ryugu in November (which I daresay will be a significant relief to Ryugu) and is due to return to Earth in 2020. At this point the coverage of this story in Science News says “That’s when the team will confirm that the spacecraft successfully collected the dust.”
A Common Cold Virus Wiped Away Bladder Cancer in One Patient
- A group of researchers have just published a paper in the journal Clinical Cancer Research which reports that cancer is vulnerable when exposed to a cold virus.
- Whilst there are many, many forms of cancer there are even more pathogens that cause common colds. This is precisely why you never build immunity to colds, because you’re not just dealing with one disease.
- This study falls firmly into the small but promising category. It only involves 15 patients who were all suffering from bowel cancer. It this won’t sound pretty but these patients were delivered a sizeable dose of common cold, in the form of Coxsackievirus-A21.
- This hour long viral jacuzzi was delivered and repeated for each patient before they were taken into surgery to have and remaining tumour removed.
- Why did they find? There was evidence that the tumours had been damaged by the virus in all the patients, but in one lucky patient the tumour had been completely destroyed!
- So what’s going on? One of the problems with cancer is its ability to sidestep the immune system (since it is made up of your body’s own cells). The Coxsackievirus damages cells which then coaxes the immune system into action, removing any compromised cells, cancer or otherwise.
- The biomechanics of this leave the cancer cells more vulnerable to this virus than healthy cells, which turns Coxsachievirus into a type of magic bullet.
- What is exciting about this study is that it’s not just an idea, this is evidence of the treatment working in practice. What’s more, it’s not using some sophisticated bespoke designer virus, this is a wild strain common cold virus that is already kicking around and could theoretically work on any human with no tweaking needed.

There is no doubt that human consciousness is remarkable, but it may not be the only show in town, and once you start considering that this entire field gets a whole lot more interesting.
Folks on one side asking “How can we convince people that climate change is a problem if we don’t advocate changes in how ourselves live?” Folks on the other side saying, “Focusing on the individual is a distraction from the things doing the ACTUAL pollution, the fossil fuel industry and corporations”. The answer of course is that BOTH ARE RIGHT.
What do you do when you need an opinion on whether to buy something, or vote a certain way, or just what to believe? Who do you go to? If you said the fever swamps of social media such as Facebook/Twitter, well you might just be the crazy uncle/aunt in your family, and you just described why things have gotten all anti-intellectual across the globe recently.
So to end this evaluation, I’m going to mark down a grade of F. Not a grade for the Earth mind you, it’s not its fault. This poor grade is on US. Because while we are taking much better action and talking about climate change more, it still isn’t enough.
On the heels of a report earlier this year that shows insect populations worldwide are crashing we have new summary report from United Nations that finds more than a million plants and animals are facing extinction as a result of human activity.
And you thought measles had been eradicated in the United States, and that it was a harmless childhood annoyance. Guess what? Not so much.
Measles kills, as does science illiteracy.
