THE summer that just keeps giving had the swallows all in a flutter last week. On the south coast of the Isle of Wight hundreds streamed past me and my family as we walked over the downs, enchanted by dart-like birds racing over the white cliffs and the green sward. Yet they were flying north-east instead of south towards Africa. Some were even coming in from the sea instead of heading out over the Channel.

The 2019 Chatham House Prize is awarded to Sir David Attenborough and Julian Hector, head of BBC Studios Natural History Unit, for the galvanizing impact of the Blue Planet II series on tackling ocean plastic pollution.

Sovereign nations typically measure economic success in terms of GDP (income) but this approach is risky as it fails to track and measure the impact of this on nature. Inclusive wealth, on the other hand captures financial and produced capital, but also the skills in our workforce (human capital), the cohesion in our society (social capital) and the value of our environment (natural capital).

Human antibody response studies are largely restricted to periods of high immune activity (e.g. vaccination). To comprehensively understand the healthy B cell immune repertoire and how this changes over time and through natural infection, we conducted immune repertoire RNA sequencing on flow cytometry-sorted B cell subsets to profile a single individual's antibodies over 11 months through two periods of natural viral infection. We found that 1) a baseline of healthy variable (V) gene usage in antibodies exists and is stable over time, but antibodies in memory cells consistently have a different usage profile relative to earlier B cell stages; 2) a single complementarity-determining region 3 (CDR3) is potentially generated from more than one VJ gene combination; and 3) IgG and IgA antibody transcripts are found at low levels in early human B cell development, suggesting that class switching may occur earlier than previously realized. These findings provide insight into immune repertoire stability, response to natural infections, and human B cell development.

In episode 32, Techworld's Scott Carey looks at Amazon's Echo and finds a dystopian future world in which our household appliances listen to us and talk back. Digital Arts editor Neil Bennett (15:06) explains why Tesla now has to design products for stupid people, and Macworld's David Price explains why mums don't like Apple's iOS 10 (28:00). We also discuss the beauty and lyricism of the German language.

The human leucocyte antigen (HLA)-B*27:05 allele and the endoplasmic reticulum-resident aminopeptidases are strongly associated with ankylosing spondylitis (AS), a chronic inflammatory spondyloarthropathy. This study examined the effect of endoplasmic reticulum aminopeptidase 2 (ERAP2) in the generation of the natural HLA-B*27:05 ligandome in live cells. Complexes of HLA-B*27:05-bound peptide pools were isolated from human ERAP2-edited cell clones and the peptides were identified using high throughput mass spectrometry analyses. The relative abundance of thousand ligands was established by quantitative tandem mass spectrometry and bioinformatics analysis. The residue frequencies at different peptide position, identified in presence or absence of ERAP2, determined structural features of ligands and their interactions with specific pockets of antigen binding site of HLA-B*27:05 molecule. Sequence alignment of ligands identified with species of bacteria associated with HLA-B*27-dependent reactive arthritis was performed. In the absence of ERAP2, peptides with N-terminal basic residues, and minority canonical P2 residues are enriched in the natural ligandome. Further, alterations of residue frequencies and hydrophobicity profile at P3, P7, and P positions were detected. In addition, several ERAP2-dependent cellular peptides were highly similar to protein sequences of arthritogenic bacteria, including one human HLA-B*27:05 ligand fully conserved in a protein from Campylobacter jejuni. These findings highlight the pathogenic role of this aminopeptidase in the triggering of AS autoimmune disease.

For the next few months Talk Evidence is going to focus on the new corona virus pandemic. There is an enormous amount of uncertainty about the disease, what the symptoms are, fatality rate, treatment options, things we shouldn't be doing. We're going to try to get away from the headlines and talk about what we need to know - to hopefully give you...

El Salvador is the smallest country in Central America yet the most densely populated. A stagnant economy, high levels of crime and violence, and natural disasters have pushed growing numbers of people to migrate without authorization or seek asylum abroad, mostly in the United States. This article explores historical and contemporary emigration from El Salvador.

From earthquakes to drought, natural disasters and climate change played a key role in migration flows in 2015. Climate-induced migration surfaced as a concern at the United Nations Climate Change Conference (known as COP21) as international organizations and policymakers have begun to recognize the growing challenges, and potential protection obligations, of such movement.

Nearly 22 million immigrants—about half of the overall immigrant population—were naturalized U.S. citizens in fiscal year 2017. In the same year, more than 707,000 immigrants became U.S. citizens. Naturalized citizens tend to have higher incomes and educational attainment compared to other immigrants, as this data-rich article explores.

Psychologists once conducted a simple experiment with far-reaching implications: They asked people to describe an instance in their lives when they had hurt someone and another instance when they had been hurt by someone else. The incidents that people described were similar whether they saw...

Macfarlane's journey begins on the Icknield Way, which runs over the chalk downs of Sussex. He starts out on a bicycle along an old Roman road that runs past an Iron Age hill-fort. As he cycles past the hill-fort he falls, damages his bicyle, and breaks a rib.However, Macfarlane gets up and continues his journey. He views the accident as

A warning, I thought superstitiously, had been issued to me: that the going would not be easy and that romanticism would be quickly punished. It was only a few miles later that I remembered the letter a friend had sent me when I told him about my plan to walk the Icknield Way. Take care as you pass the ring-fort, he had written back. When I mentioned the fall later, he was unamazed."This was an entry fee to the old ways, charged at one of the usual tollbooths, " he said. "Now you can proceed. You're in. Bone for chalk: you've paid your due." It was the first of several incidents along the old ways that I still find hard to explain away rationally." (p.43).

Throughout the book, Macfarlane risks meeting the supernatural. He spends the nights camping near Iron Age barrows. He sleeps in circular Pictish shielings. Finally he decides to sleep in Chanctonbury RIng in Sussex because author Laurie Lee had slept there while walking over England in the 1930's.

I first learned about Chanctonbury Ring when I read about called Sussex Cottage written by Esther Meynell in 1936. The ring contains a temple built by the Romans on a previously inhabited Bronze and Iron Age fort site. According to legend, Julius Caesar and his legions ride around the ring. It is also possible to summon the devil by running around it a certain number of times. There are a number of internet sites with chilling stories of uncanny experiences in Chanctonbury Ring:

Oblivious to the possibility that he may be rousing some kind of supernatural being, Macfarlane spends a night in Chanctonbury Ring, but gets little rest. First he walks around the ring, then beds down for the night. He is awoken by  human-sounding voices moving around the ring until two voices meet directly over his head. Eventually the voices go away and he is able to go back to sleep although he does not feel rested in the morning. Later in the day Macfarlane meets up up with an archaeologist friend and they discuss why it was a bad idea to sleep in the ring. However, it is not until he gets home that Macfarlane researches the folklore of Chanctonbury Ring and realizes that it is one of the most malevolently haunted spots in England.

What's interesting is that while Macfarlane is aware of the many centuries of human history that his paths have run through, and of the theories that the paths exist throughout time, he does little research on the supernatural history of the places where he travels. These places seem to do their best to make him aware of their history and their special qualities. The supernatural seems to forcibly come to him although he does his best to remain ignorant of its existence.

This syrup is delicious and well worth the time involved. While it tastes sweet it is natural and sugar-free. Add a tablespoonful to any chopped fresh fruit - berries, mango, pineapple, papaya, banana, grapes - and it will balance and enhance the flavours. It's also great served over waffles, crepes or ice cream.

Governors in several natural resource-dependent states said recently they will have to continue to cut public education funding because prices for oil and coal have not rebounded.
