A crystallographic indexing algorithm, pinkIndexer, is presented for the analysis of snapshot diffraction patterns. It can be used in a variety of contexts including measurements made with a monochromatic radiation source, a polychromatic source or with radiation of very short wavelength. As such, the algorithm is particularly suited to automated data processing for two emerging measurement techniques for macromolecular structure determination: serial pink-beam X-ray crystallography and serial electron crystallography, which until now lacked reliable programs for analyzing many individual diffraction patterns from crystals of uncorrelated orientation. The algorithm requires approximate knowledge of the unit-cell parameters of the crystal, but not the wavelengths associated with each Bragg spot. The use of pinkIndexer is demonstrated by obtaining 1005 lattices from a published pink-beam serial crystallography data set that had previously yielded 140 indexed lattices. Additionally, in tests on experimental serial crystallography diffraction data recorded with quasi-monochromatic X-rays and with electrons the algorithm indexed more patterns than other programs tested.

Here come the stinkbugs...With the cooler temperatures of fall the brown marmorated stinkbug begins a determined quest to find a warm place to spend the winter. Crowding around window screens and searching for other ways to get inside, homeowners in the United States will share their indoor living space this winter with millions of brown marmorated stinkbugs. In this video Gary Hevel, an entomolgist at the Smithsonian's National Museum of Natural History, shares some information about these interesting creatures, as well as some advice about how to deal with those that inevitably gain entry to your home.

During evaporation of natural and synthetic K–Mg–Cl brines, the formation of almost square plate-like crystals of potassium carnallite (potassium chloride magnesium dichloride hexa­hydrate) was observed. A single-crystal structure analysis revealed a monoclinic cell [a = 9.251 (2), b = 9.516 (2), c = 13.217 (4) Å, β = 90.06 (2)° and space group C2/c]. The structure is isomorphous with other carnallite-type com­pounds, such as NH4Cl·MgCl2·6H2O. Until now, natural and synthetic carnallite, KCl·MgCl2·6H2O, was only known in its ortho­rhom­bic form [a = 16.0780 (3), b = 22.3850 (5), c = 9.5422 (2) Å and space group Pnna].

A report released Thursday by a labor group-affiliated Washington think tank is questioning the education provided by an online public school program that says it is in a union fight.

The report by In the Public Interest, a group funded by unions, says the thousands of students enrolled in the California Virtual Academies online public school known as CAVA are receiving a  substandard education by most measures.

"So in every year since CAVA began graduating students, with the exception of 2013, it has produced more dropouts than graduates,” said Shahrzad Habibi, who authored the report.

She said state test score data show that 71 percent of California public schools performed better than the virtual academies.

The report calls on California officials to investigate the online schools’ administration and finances.

California Virtual Academies enrolls about 14,000 kindergarten to 12th grade students through 11 sites, including those in Los Angeles, San Diego, and Fresno. It is run by a national for-profit company called K12 Inc.

In a written statement, California Virtual Academies did not dispute the reported low student performance numbers, but denied other allegations in the study, which it called “inaccurate and deeply flawed.”

“The report relies primarily on misinformation from the California Teachers Association — the union currently engaged in a coordinated and well-funded distortion campaign to unionize the eleven independent California Virtual Academies charter schools.”

In the Public Interest, which supports the work of labor unions, partnered with the American Federation of Teachers last year on a website to track for-profit charter school companies.

Evidence exists linking three cancers and two other health problems with chemicals used in herbicides in the Vietnam War, a committee of the Institute of Medicine (IOM) has concluded.

Radon in household water supplies increases peoples overall exposure to the gas, but waterborne radon poses few risks to human health, says a new report by a committee of the National Research Council.

The federal government should not increase the maximum level of copper allowed in drinking water, because higher levels could lead to liver poisoning in infants and children with certain genetic disorders.

The evidence does not support a causal link between sudden infant death syndrome (SIDS) and either the diphtheria, tetanus, and whole-cell pertussis (DTwP) vaccine or exposure to multiple childhood vaccines, says a new report from the Institute of Medicine of the National Academies.

Scientific evidence links mold and other factors related to damp conditions in homes and buildings to asthma symptoms in some people with the chronic disorder, as well as to coughing, wheezing, and upper respiratory tract symptoms in otherwise healthy people, says a new report from the Institute of Medicine of the National Academies.

The U.S. Environmental Protection Agencys standard for the maximum amount of fluoride allowed in drinking water -- 4 milligrams of fluoride per liter of water -- does not protect against adverse health effects.

A limited body of evidence suggests an association between military service and later development of amyotrophic lateral sclerosis (ALS), a rare but fatal neurodegenerative disorder, says a new report from the Institute of Medicine.

Short-term exposure to current levels of ozone in many areas is likely to contribute to premature deaths, says a new National Research Council report, which adds that the evidence is strong enough that the U.S. Environmental Protection Agency should include ozone-related mortality in health-benefit analyses related to future ozone standards.

Evidence exists that people who lived or worked at Camp Lejeune Marine Base in North Carolina between the 1950s and 1985 were exposed to the industrial solvents tricholorethylene (TCE) or perchloroethylene (PCE) in their water supply, but strong scientific evidence is not available to determine whether health problems among those exposed are due to the contaminants, says a new report from the National Research Council.

As immigrants and their descendants become integrated into U.S. society, many aspects of their lives improve, including measurable outcomes such as educational attainment, occupational distribution, income, and language ability, but their well-being declines in the areas of health, crime, and family patterns, says a new report from the National Academies of Sciences, Engineering, and Medicine.

Although more than $500 million in federally funded research on Persian Gulf War veterans between 1994 and 2014 has produced many findings, there has been little substantial progress in the overall understanding of the health effects, particularly Gulf War illness, resulting from military service in the war, says a new report from the Institute of Medicine (IOM) of the National Academies of Sciences, Engineering, and Medicine.

The latest and final in a series of congressionally mandated biennial reviews of the evidence of health problems that may be linked to exposure to Agent Orange and other herbicides used during the Vietnam War changed the categorization of health outcomes for bladder cancer, hypothyroidism, and spina bifida and clarified the breadth of the previous finding for Parkinson’s disease.

Although the immediate side effects of antimalarial drugs are widely recognized, few studies were designed specifically to examine health problems that might occur or persist months or years after people stopped taking them.

Sixty-four children and teens in New York State are suspected of having a mysterious inflammatory syndrome that is believed to be linked to COVID-19, the New York Department of Health said in an alert issued Wednesday. A growing number of similar cases — including at least one death — have been reported in other parts of the U.S. and Europe, though the phenomenon is still not well-understood.

Pediatricians say parents should not panic; the condition remains extremely rare. But researchers also are taking a close look at this emerging syndrome, and say parents should be on the lookout for symptoms in their kids that might warrant a quick call to the doctor — a persistent high fever over several days and significant abdominal pains with repeated vomiting, after which the child does not feel better.

"If [the child is] looking particularly ill, you should definitely call the doctor," says Dr. Sean O'Leary, a pediatric infectious disease specialist at Children's Hospital Colorado Anschutz Medical Campus and member of the infectious disease committee for the American Academy of Pediatrics.

The new condition associated with COVID-19 is called Pediatric Multi-System Inflammatory Syndrome. Symptoms include persistent fever, extreme inflammation, and evidence of one or more organs that are not functioning properly, says cardiologist Jane Newburger, a professor of pediatrics at Harvard Medical School and director of the Kawasaki Program at Boston Children's Hospital.

"It's still very rare, but there's been a wave of cases. Physicians and scientists are working hard to understanding the mechanisms at play, and why only some children are so severely affected," Newburger says.

Some symptoms can resemble features of Kawasaki Disease Shock Syndrome. Kawasaki Disease is an acute illness in children involving fever, together with symptoms of rash, conjunctivitis, redness in the lips, tongue and mucous membranes of the mouth and throat, swollen hands and/or feet, and sometimes a large group of lymph nodes on one side of the neck, says Newburger. Some children with the condition develop enlargement of the coronary arteries and aneurysms in those blood vessels.

A small percentage of Kawasaki cases go on to develop symptoms of shock – which can include a steep drop in systolic blood pressure and difficulty with sufficient blood supply to the body's organs. Kawasaki disease and KDSS more often affect young children, although they can sometimes affect teens, Newburger says.

Some cases of the new inflammatory syndrome have features that overlap with KD or with KDSS — including rash, conjunctivitis, and swollen hands or feet. The new inflammatory syndrome can affect not only young children but also older children and teens.

But patients with the new syndrome have lab results that look very different, in particular, "cardiac inflammation to a greater degree than we typically see in Kawasaki shock syndrome," which is usually very rare, O'Leary says. In New York City and London, which have seen large numbers of cases of COVID-19 cases, "those types of patients are being seen with greater frequency."

Some patients "come in very, very sick," with low blood pressure and high fever, O'Leary says. Some children have had coronary artery aneurysms, though most have not, he adds.

Other patients exhibit symptoms more similar to toxic shock syndrome, with abdominal pain, vomiting and diarrhea and high levels of inflammation in the body, as well as the heart, O'Leary says. Most cases are treated in the intensive care unit, he says. Treatment includes intravenous immunoglobulin, which can "calm the immune system," says Newburger, as well as steroids and cytokine blockers.

The evidence so far from Europe, where reports of the syndrome first emerged, suggests most children will recover with proper supportive care, says O'Leary, though one adolescent, a 14-year-old boy in London, has died, according to a report published Wednesday in The Lancet.

Most children with the syndrome, O'Leary and Newburger note, have either tested positive for a current infection with the coronavirus, or for antibodies to the virus, which would suggest they were infected earlier and recovered from it.

And, according to case reports, some of the kids with the inflammatory syndrome who tested negative on coronavirus tests had been exposed at some point to someone known to have COVID-19. The inflammatory syndrome can appear days to weeks after COVID-19 illness, doctors say, suggesting the syndrome arises out of the immune system's response to the virus.

"One theory is that as one begins to make antibodies to SARS-COV-2, the antibody itself may be provoking an immune response," says Newburger. "This is only happening in susceptible individuals whose immune systems are built in a particular way. It doesn't happen in everybody. It's still a really uncommon event in children."

In late April, the U.K.'s National Health Service issued an alert to pediatricians about the syndrome. Reports have also surfaced in France, Spain and Italy, and probably number in the dozens globally, Newburger and O'Leary say, though doctors still don't have hard numbers. Newburger says there needs to be a registry where doctors can report cases "so we can begin to generate some statistics."

"Doctors across countries are talking to each other, but we need for there to be some structure and some science so that everybody can interpret," she says.

Earlier this week, the New York City Health Department issued an alert saying 15 children ranging in age from 2 to 15 had been hospitalized with the syndrome. Newburger says that she's been contacted about cases in New Jersey and Philadelphia, as well.

While the syndrome's precise connection to the coronavirus isn't yet clear, O'Leary says the fact that the children in most of these cases are testing positive for exposure to the virus, one way or another, provides one point of evidence. The sheer number of cases — small in absolute terms, but still "much higher than we would expect normally for things like severe Kawasaki or toxic shock syndrome" — provides another, he says.

And then there's the fact that most reports of the syndrome have come out of the U.K. and New York City, places that have been hit with large numbers of COVID-19 cases.

"It's pure speculation at this point," he says, "but the U.K. cluster kind of went up about a month after their COVID-19 infections went up, which would suggest that it is some kind of an immune phenomenon."

Audrey Hepburn I am not, but every once in a while, a girl’s gotta go for the gamine look, right? The ankle-length or capri trousers, the ‘50s pink and black color scheme. This is not the ‘’Breakfast at Tiffany’s” Audrey Hepburn, but the 1957 “Funny Face” Audrey, the intellectual beatnik girl who agrees to do a photo modeling shoot for Fred Astaire in exchange for a trip to Paris, where she can to worship at the feet of her “empathicalism” guru, Professor Flostre, who turns out to be just another “mec” on the make.
 
Of course I had to sneak in some commentary in this ensemble: the shirt in sweetheart-pink with stylized black silhouettes of classic runway shapes over the years …  and the shoes, with the pink-and-black face of a sassy manga girl. This one I like. Some of the sex-bomb manga girl illustrations look more like teen boy fantasy porn versions of those classic Keane portraits of solemn-faced, big-eyed children.

The only woman who comes close to achieving the empty handbag is the Queen, who, if rumor is believed, carries only a handkerchief and lipstick and eyeglasses in hers, maybe one or two other items, and on Sunday some money for the church collection plate. I’m convinced she keeps it handy mostly as a prop. Poor lady: it’s always a sedate British-made Launer handbag and she orders four new ones a year. Maybe at least in her imagination she goes online and buys a Stephen Sprouse Louis Vuitton neon graffiti bag, just for the heck of it.]

Someone just told me that pink and gray were Vassar’s colors. I would say, “Go Vassarettes!” but, one, Vassarette is a line of brassieres, and, two, the Vassar mascot is The Brewer, for the profession of its founder, Matthew Vassar. You go, Seven Sisters girls and guys!

The scarf is one of two I picked up on vacation – for some reason insect themes are big just now. This one has little gray ants marching over a pink field, a reminder of – what? Teamwork? Conformity? Time to call the exterminator? The other scarf, which I’ll wear presently, is the color of a ripe nectarine, with a pattern of vividly colored beetles. Scarabus chic. Dashing, no?

The glittery pink shirt is one more example of that contrast that I like, against the matte gray knit of the sweater (indoor-outdoor wear for L.A. summers, going from AC to Fahrenheit in a flash). Which explains the vast and shady hat – like a veranda on my head!

I was surprised at myself for buying these shoes – silver and bright pink; when would I ever be wearing that? But there they are, slingbacks made by “Emma Hope’s shoes, Regalia for feet,” an irresistible name.

The oval seal with the maker’s name reminded me of the oval seal on shoes made by Rayne, the 19th-century London shoemaker that had shod the women of the royal family for decades (but not the last two generations of those chic ladies: Diana, Princess of Wales, and Katherine, Duchess of Cambridge).

Please don’t blame Rayne for the Queen’s inordinate fondness for platform peeptoe shoes – her mother made her do it. Literally. Those royal ladies – the Queen, her late mother and late sister, Margaret – were quite short, and those shoes boosted their height. But still …

Here is Rayne’s website for a look at some of the glamorous and glorious shoes for feet past and present – including Anna Pavlova’s, prima ballerina assoluta. Mary Quant designed for Rayne. And before you look, that old caution:  If you have to ask how much …  

A pair of Rayne shoes is on my fantasy list for thrift-store finds, along with a Fortuny dress and a wild Schiaparelli hat. I believe, I believe...

Urban vegetation could have been overlooked as valuable above-ground carbon storage, according to researchers. They estimated that 231,521 tonnes of carbon were stored in above-ground vegetation in a UK city, the majority of which (97 per cent) in trees. This was 10 times the amount estimated from national figures for the same city area.

The impact of air quality on public welfare is important to policy development. However, it is difficult to make a clear link between the two when air pollution tends to be reported at a country level and wellbeing is an individual measure. A new study takes a step further towards linking the two by analysing regional level air quality across the EU and relating it to levels of life satisfaction.

UN researchers highlight the need to develop better ways to measure the impacts of climate change on children's health. They suggest more attention be given to impact analysis of different social groups and ages, as well as nutrition.

A recent study has investigated how exposure to a variety of environmental pollutants, including heavy metals and chlorinated compounds, affects the height and body mass index (BMI) of local communities. It found that some pollutants could be causing reduced height and BMI, which can be explained in part by the pollutants??? disrupting effects on the hormonal system.
