SOS: Save our Science - Yet More Alien Bacteria. Really!

ResearchBlogging.org

I saw James Watson last night! and I have his autograph. :D He was in London, in conversation with Brenda Maddox, who wrote Rosalind Franklin's biography. It was fascinating, although I have to admit that he was clearly on his very best behaviour and kept the outrageous comments to a minimum. I'd also like to take this as my excuse for any 'enthusiastic' comments in the post below, which is a great peiece of storytelling. This week was also my first outreach talk to school children, I think it went rather well, although I'll be writing much more on that in a few weeks.
 
OK, so this is another story that I was asked to write (Yay!). Once again there have been reports of alien bacteria in meteorites (that’s the third time in 14 years, if you’re counting).Here is the latest story, I suggest you read it first as it makes what I’ll be saying more surprising. Go on, I’ll wait. Sounds good doesn’t it, highly acclaimed doctor with a paper in a prestigious sounding journal, with authoritative quotes and everything. Not only that but the journal seems to have gone to great lengths to ensure extensive peer reviewing of the findings before publishing. Well, as with many stories that get NASA plastered to them, it’s got a lot of people rather riled up and for a lot of different reasons. Read on and I’m sure you’ll see why.

This is a fantastic story, I’ve never seen so many mistakes made by so many people in so many different ways, it’s quite a feat of engineering really. Also it does go to show that some people really do never learn. The roots of this story lie all the way back in 1997 when NASA scientists reported finding bacterial fossils in a meteorite from Mars.

This astonishing and revolutionary finding was reported by Richard B. Hoover who works at NASA’s Marshall Space Flight Centre. This was discounted shortly afterwards when it became apparent that the structures observed were probably contaminants from the time the sample spent on Earth before being studied. Now some people would learn from such a colossal mistake that was a huge embarrassment for NASA and Hoover personally.

This bacterium from Earth looks strangely like some observed in these meteorites (source)

Hoover, however, is made of stronger stuff. After his error in 1997 I’d like to say that he improved his working scheme, ensuring all samples were properly sterilised and cross checked before announcing proof of alien life to the public. But he didn’t. He returned in 2007, although with less impact (mainly due to lack of a successful publication), to say that he really had found life, this time in a totally different type of meteorite. Thankfully this time he attracted less attention.

Now, to the delight of many, Richard B. Hoover has returned to the public stage, thanks in no small part to the lovely people at FOX news, with another attempt. He’s still looking at the same rocks from 2007 but this time he REALLY thinks he’s got it.

SOS: Save our Science - Drink Hearty Lads (and Ladies)

ResearchBlogging.orgHi Everyone. Hope there's still people out there reading this. Would be great to hear from you. Sorry things have been a bit slow, there's a lot going on this term, which I hope to write about (in part) soon. This new rotation is really fun, although quite long hours, and I've got loads of other projects going on relating to Science Communication, as many of you may already be aware. It means I'm not getting much time to sit and write articles on here though. I will be working hard to try and get back to ClearSci as much as possible, so hopefully more will be going on around here.


Anyway, so here's a fun story that is an issue I've been looking forward to having a go at. Everyone always has some new story about how alcohol is good for you or bad for you, and usually it depends on what you measure and whether it's the alcohol itself or something else (e.g. tannins in red wine) which is helping you out. This latest is cool because it pulls together a lot of research from the last 30 years, and actually finds some benefits, in certain instances, but also points out the importance of moderation. Enjoy. :)


This is a debate that I find quite interesting, especially since everyone seems to be more than a little biased in their desired outcome. It is the endless search for positive effects of drinking alcohol. A new meta-analysis (re-examination of lots of old data from different studies) of alcohol research may finally be able to put part of this issue to rest.

SOS: Save our Science - Bug Battle

ResearchBlogging.orgThis post was a request from a reader (Yay!). I've got a lot of different projects going on at the moment so have been a bit slow with the posting. Hopefully I'll be posting about my latest lab soon. There's still a lot to write when I get the time. We had a lot of fun last week meeting the students interviewing to join my course next year and the lab work is going well. There is a much more theoretical element to it, which I've been enjoying. Anyway, so this is a bit of a proto-story really. A possible explanation for the disappearance of bees worldwide; though the real science is still under wraps.

Pollinating insects, like bees, are disappearing across the world. The phenomenon is known as colony collapse disorder (CCD). If CCD continues as it is the world stands to lose most, if not all, pollinating species, which stands to rapidly wipe out all flowering plant species and would severely alter every land based ecosystem. A key element in understanding CCD was uncovered over two years ago, but is only just emerging as published work.

CCD is being studied by a dedicated group of researchers in the US Department of Agriculture’s Bee Research Lab. The rapid decline in colonies of pollinating insects due to CCD was originally observed in the US but has since been identified around the globe, though it has yet to arrive in some countries, including the UK.

SOS: Save our Science - Seeing Sharks!!

ResearchBlogging.org
This is the end of my first week in the second lab, it's pretty fun so far, quite enjoying the variety of things I've become involved in and will hopefully get some very exciting data. It's going to be a busy term though. Anyway, more on that later. Here's some fishy news from Australia!


It is a commonly quoted fact that sharks can smell a single drop of blood in over 100 litres of water. As a top predator a shark needs highly developed senses to hunt, so it is surprising that many species are probably completely colour blind! Sharks still have excellent vision, but it is monochromatic i.e. Black and white.

SOS: Save our Science - Preventing Pandemic

ResearchBlogging.org


Hey! I've been busy finishing my first project and after some last minute panicking it's all over and I'm moving on from chickens to yeast, but before I do I wanted to share this new story. A breakthrough in preventing the spread of Bird Flu, that has applications in protecting against a wide range of other viruses. This is the sort of story I've been looking forward to writing for a while, I hope you'll see why.


A group of researchers may have found a way to prevent the spread of bird flu through domestic populations, a revolution which could significantly reduce the risk of humans becoming infected. Not only that, but this technique could be easily used to protect against any viral infection in almost any species. It could even eventually be used to protect ourselves. This method requires no vaccinations and provides life-long protection from a broad range of different avian flu strains.

SOS: Save our Science - Cryptochrome, lord of time.

ResearchBlogging.org

 I knew it'd happen sooner or later, I've started falling behind on postings. I'd hoped to put this up on New Year, but that didn't happen. Anyway, Happy New Year to all, hope you all enjoyed yourselves. I've been writing the report on my first project. The first draft is now done. Still a lot to do, and only 1.5 weeks until it's back to work. The next project is all about cytoskeleton and growth in yeast, so a bit different, I'll tell you more once I actually know anything...

So this is a relatively new paper I found, investigating how flies, and possible humans keep track of the time of day and how this is affected by our environment i.e. the sun. It seemed appropriate to do a time piece to see in the new year. Also I'm really excited as this will be my first official Research Blogging post!!

How do you know if it’s day or night? Simple, right? You look at your watch or you look outside. The differences are pretty obvious. But your body actually keeps track of these things itself. Certain proteins in your body keep track of the time of day. This system has been around for billions of years, and is shared between plants and animals.

The subconscious ability to tell night and day depends on circadian rhythms; regular changes in the presence and activity of timekeeper proteins within a part of your brain called the pineal gland (so named because it looks like a pine cone). Experiments have shown that in a room with no clocks and no changes in light levels a human will fall into a roughly 24 hour cycle of sleeping and waking (average 24 hours 11 mins). The average cycle differs between species and in some arctic species appears to be intermittent. Although the cycle is entirely self-sustaining it is trained and altered by light input, modifying it to be more exactly 24 hours long. This involves light sensitive proteins in your eye which signal to the pineal gland.

SOS: Save our Science - Last minute Christmas

Now that Christmas is drawing to a close our thoughts turn exuberantly towards the January sales. Blowing all of our new gift vouchers and our remaining money on last minute impulse buys. The good news for all of us is that we may be able to blame these rash choices on our genes.

Impulsivity is described as doing something without foresight, and understanding it has major implications for a range of psychiatric disorders as well as explaining what will be going on in the high street over the next few weeks. Impulsive behaviour is very complex and under the control of many genes. It has many aspects, most especially reduced inhibitions, but also including reduced attention span, limited awareness of consequences and inappropriate responses to rewards. Impulsive behaviour is also known to be inherited in some cases. This new study shows that it is possible to identify the genes involved in this behaviour.

SOS: Save our Science - Save our Salmon

This is a story that's been going for a long while. The concerns over the effects of fish farming on wild fish populations. Also it's nice to take the science outside for a change. This new research is quite interesting and was well reported. Although the actual findings still need a lot of work.

A sudden population crash in wild salmon during 2002 caused mass panic for the authorities in Canada. This coincided with closer monitoring of farmed salmon, and resulted in the blame being placed on parasites transferred from farmed fish. The phenomenon has drawn the attention of many researchers and a new study appears to show that although there is transfer of parasitic sea lice between farmed and wild salmon it cannot be responsible for the decline in population.

SOS: Save our Science - Inside Endometriosis

I wrote this after reading the BBC article about the same paper. The work was very poorly explained, and the findings were completely mistranslated. However, this time the original paper was pretty good, although filled with statistics (Bleh!)

All women hate periods, but a small percentage have it much worse than others. They suffer from endometriosis; severe pains and poor fertility throughout their reproductive life. The illness is often passed down through families, so must be partially dependent on genes. A new study has identified where some of these genes may occur.

SOS: Save our science - Good Science or good publicity?

So this is the second part of my ramblings, and probably the most important bit. This part is all about accurately reporting on science in the media. I’m going to write about science stories that have got people talking, the ones that actually make it into the mainstream. I’m going to write about them in a pragmatic (and possibly occasionally cynical) manner that cuts to the truth of the matter without all the overblown revolutionary claims that are usually applied to these stories.

It seems appropriate to start with this one; I should say before I begin that I do strongly believe in NASA and hope they get the shuttle program back on track soon. But as far as overblowing things goes, I thought this was pretty good.

(Ed. Since this whole story is rapidly collapsing into random mud slinging I would like to point out that this post was written to highlight the way in which science can be distorted by the media, and is not meant as a personal affront to anyone directly involved).
Good science or good publicity?

Good Publicity

Big news! NASA has found aliens living in California (like we didn’t already know) and everyone is getting excited that we’re not alone in the universe. But is it really that big a deal, or has NASAs publicity department just been very clever in distracting everyone from the fact they still haven’t managed to get the shuttle off the ground?

To start with, I’m going to assume that the science underlying all of this is actually correct, and we’ll look at the actual implications and meanings of such a discovery and how it can be blow out of all proportion by the press. Later, I will briefly look at why this work seems to have very little sound scientific foundation and does not really demonstrate anything important.
