In some respects, seeing thriving populations of common species might well be a better indicator of 'health' than increases in the numbers of occasional animals often at the margins of their ranges.

https://www.theguardian.com/environment/2018/dec/20/great-pacific-garbage-patch-20m-cleanup-fails-to-collect-plastic). The device is intended to help remove floating plastic in the Pacific between California and Hawaii. Although it scoops up plastic, the material is escaping again. Hopefully, tweaks to the device will make it an effective nemesis for this ubiquitous human waste.
https://www.theguardian.com/environment/2018/dec/20/risks-of-domino-effect-of-tipping-points-greater-than-thought-study-says).

The gene enables the plant filter out harmful pollutants such as chloroform and benzene. As I keep telling my students, the gene is not necessarily the exclusive property of the rabbit (many genes are shared by organisms e.g. humans share circa 20% of the genes a yeast has). So the rabbit was, presumably, a convenient source.

Their advice is that surgeons should take more care when sterilising their instruments. I seem to remember, however, that earlier studies with prions (highly resistant proteins implicated in CJD), suggested that there was no such thing as a completely safely re-utilisable (after sterilisation) surgical instrument?

This certainly makes sense in terms of the physics but, I suspect, that 'warming' was used, as the actual magnitude of the change is slight. 'Slight', however, does not mean without substantial consequences for the planet and its surface dwellers.

https://www.theguardian.com/science/2018/dec/10/tread-softly-because-you-tread-on-23bn-tonnes-of-micro-organisms). They estimate that more than 20 billion tons of microorganisms live below the surface. This is a greater biomass than the planet's current human population, in spite of the region being characterised by intense heat; sparse nutrition and mind-boggling pressures. Some organisms appear to have survived (largely in a state of stasis) buried in situ for millions of years. The scientists speculate as to whether colonisation of life zones of the planet have gone from surface to interior or vice versa. That actually may not matter too much as, I suspect, that life, being opportunistic, will take advantage of vacancies that occur in either location. So, if humans manage, by their actions, to eliminate much of the life on the surface, some 'deep life' will come to the surface, certainly speeding up the re-population process.

This makes it the oldest known bird to be actively reproducing with her 'long term lover' (actually, albatross pair-bond for life, if at all possible). The pair had to have only 2 chicks survive to breed to essentially replace themselves but, in spite of this, albatross numbers are in rapid decline on a world-wide basis. Wisdom needs to keep going.

They note that there is a similar protein in humans, Regina, with a comparable action. Customers of alternative health shops have postulated for years that Royal jelly is a valuable addition to the human diet and, in deed, there is reasonable evidence that the substance increases longevity in animals from nematode worms to mice. The Stanford group reportedly believe that developing Regina (or variants of the molecule) might have medical applications in the treatment of neurodegenerative diseases (including Alzheimer's) as well as wound healing.

https://www.theguardian.com/science/2018/dec/04/scientists-develop-10-minute-universal-cancer-test). Small amounts of cancer cells with their modified DNA appear in the blood. The cancer cell DNA has a different pattern of methyl groups from that found in normal cells, causing them to respond differently to gold nanoparticles added to the samples. This produces a distinctive difference in the colour of the suspensions with (remaining pink) and without (changing to blue) cancer cells. The test has, thus far, been carried out only on breast, prostate and colorectal sufferers but there is an intention to see what it does in other cancer groups. Although this screen does not tell the tester where the cancer is located or how problematic it is likely to be (these would require more detailed and traditional investigations), as a rapid test, it does seem to be a very promising development.

It chimes with a comment by one of the Katowice (Poland and scene of the UN Climate Change conference) coal miners to the effect that those ecologists ought to remember who is doing more for the planet (ecologists or coal miners)! Such attitudes and the political responses to them might well be the planet's epitaph.

In Australia (currently an Environmental bad-boy), enlightened schoolchildren are protesting about climate damaging government policies but, in France, people are rioting partly about increases in fuel prices (a measure designed to reduce greenhouse gas emissions). The UK government appears hell-bent on encouraging fracking and the US wants more coal mining and oil extraction even in national parks. As they say "the prognosis doesn't look too good". It seems that people generally know what needs to be done but they would rather that someone else did it at their expense.

Certainly, they can be cultured much more quickly than beef, chicken, lamb and pork and are associated with nothing like the same environmental problems. There is not actually much anatomical difference between a locust and a prawn (the former possibly has the cleaner diet) but I still think that people (not withstanding the popularity of "I'm a Celebrity: Get Me Out of Here") will have to be inventive to get the population heavily into insect grub.

They point out that, not only are we losing food crops in many parts of a warming, sometimes more arid world, but heatwaves are also increasing death-rates in both younger and older citizens (they are more vulnerable). Transmitted human diseases, such as dengue fever, are also spreading to new regions of the planet. They think that we should take the situation seriously.

The London Embankment cycle way, used by tens of thousands of cyclists per day and occupying 1 lane of a 4 lane road, is being threatened by a combination of property groups, motorised transport bodies and taxi companies. I would have thought we needed more provision for cyclists in our cities, not less!
https://www.theguardian.com/world/2018/nov/29/scientists-discover-spider-species-that-feeds-its-young-milk).Although we normally associate milk production with Mammals, other species, e.g. pigeons, produce 'crop milk'. Consequently, the idea of producing body secretions to give one's offspring a helping start is, perhaps, more widespread than was earlier thought. Some species even donate their bodies to their progeny (they get eaten).

Apparently, the cold seas result in these cold-blooded animals becoming moribund and geography makes in difficult for them to escape to warmer waters. There have also been a recent mass stranding of whales in a remote area of New Zealand.
https://www.theguardian.com/environment/2018/nov/28/report-urges-network-rail-rethink-scale-line-side-tree-felling). The rail folk seem to 'hate' the trees, whose falling autumn leaves can cause delays and storms can blow trees onto the tracks. Having said that, trees are important removers of greenhouse gases (which diesel trains contribute to); provide an effective visual (and even a bit of sound deadening) screen for people living near the tracks; give rail passengers something nice to look at and might even reduce the possibility of landslides. The rail track system (like motorway verges) makes up a surprisingly high area of unbuilt and unfarmed land in the UK. Viva the trees!

It reminded me of the Masters programme carried out, under my distant supervision, by Dr Kate Evans before she became @elephantkate, after changing her beast. Her animals (especially the females) also had a complex social life. It was also remarkable how much of the water obtained by the animals at certain times of the year came from their prey. There were also some interesting associations between social status and their burdens of worm parasites as evidenced by eggs in the faeces (as these had to be collected fresh, there was a fraught risk assessment for the project).

It's just a pity that there are votes to be obtained by ignoring (or even robustly contradicting without any actual evidence) the advice presented. I have frequently noted that that the basic problem is that the time courses for global change and the political cycles have very different periodicities. Short-termism wins every time.
https://www.theguardian.com/science/2018/nov/25/woman-inherited-fatal-illness-sue-doctors-groundbreaking-case-huntingtons). The hospital doctors presumably did not formally inform the immediate family of the man because of patient confidentiality (but they might have suggested that the man should inform his children as they would have a 50% chance of inheriting this condition which currently has no cure). The woman claims that, had she been informed, she would have had an abortion rather than giving birth to her daughter 8 years ago (as the woman has inherited the condition, also giving her daughter a 50% chance of developing the disease). This is a difficult one (and not, in my view, one for the legal eagles). The situation seems straight forward as described but the availability of gene testing techniques is reportedly revealing odd family secrets and misconceptions (no pun intended). What if the father had not actually conceived his 'daughter' and, because she was informed of his condition, she had an entirely unnecessary abortion? Would hospital be liable for this? I think that medical ethics needs to get on the case and give some clear guidance.

https://www.theguardian.com/tv-and-radio/2018/nov/19/top-filmmakers-back-penguin-intervention-on-attenborough-show). Arguments seem to revolve around the issue of the natural history film maker's code requiring them to not normally interfere with the lives of the animals they are studying (e.g. they would not be expected to intervene, on either side, in a predator versus prey encounter). The camera folk argue (not unreasonably) that no animal was probably directly disadvantaged by digging the escape slope (picking the penguins out of the ravine would have been different). Having said that, it could be the case that some, as yet unarrived, scavengers missed out as a result of the film-makers actions. I suspect, however, that I would have done the same under these circumstances.

This essentially means that the disturbed mood in males is strongly linked to their endocrine status (so, either depression lowers testosterone or lowered testosterone, as in aging cohorts, tends to elevate depression). Although not currently recommended by NICE, testosterone might be a relatively cheap therapy for some forms of male depression.
