Breitburg and her team want to determine just how much stress they cause. Over the next five years they will conduct a series of lab and field experiments that examine how diel-cycling hypoxia and the associated acidification affects the growth and disease rates in striped bass, the eastern oyster and other ecologically and economically important Chesapeake Bay species. They will also study the animals’ behavioral responses to these changes.

Smithsonian scientists have confirmed that chytridiomycosis, a rapidly spreading amphibian disease, has reached a site near Panama’s Darien region. This was the last area in the entire mountainous neotropics to be free of the disease. This is troubling news for the Panama Amphibian Rescue and Conservation Project, a consortium of nine U.S. and Panamanian institutions that aims to rescue 20 species of frogs in imminent danger of extinction.

Death-associated protein kinase 1 (DAPK1) is a serine/threonine protein kinase that regulates apoptosis and autophagy. DAPK1 is considered to be a therapeutic target for amyloid-β deposition, endometrial adenocarcinomas and acute ischemic stroke. Here, the potent inhibitory activity of the natural anthraquinone purpurin against DAPK1 phosphorylation is shown. Thermodynamic analysis revealed that while the binding affinity of purpurin is similar to that of CPR005231, which is a DAPK1 inhibitor with an imidazopyridazine moiety, the binding of purpurin was more enthalpically favorable. In addition, the inhibition potencies were correlated with the enthalpic changes but not with the binding affinities. Crystallographic analysis of the DAPK1–purpurin complex revealed that the formation of a hydrogen-bond network is likely to contribute to the favorable enthalpic changes and that stabilization of the glycine-rich loop may cause less favorable entropic changes. The present findings indicate that purpurin may be a good lead compound for the discovery of inhibitors of DAPK1, and the observation of enthalpic changes could provide important clues for drug development.

We used to make a big deal out of Casual Fridays at work.  But now that we're entering the dog days of summer, is anyone dressing up?

Mark Austin Thomas: Business analyst Mark Lacter, dare I ask what you're wearing?

Mark Lacter: This is radio for a reason, Mark!  And certainly, don't ask that question at the L.A. Daily Journal newspaper, which recently issued a memo that laid down the law on what's not considered appropriate attire.  As in, no jeans, no sneakers (except for messengers), no sandals or flip-flops, no halter tops, no spaghetti straps, no tee-shirts.  Also, no shorts, leggings, or exercise pants.  And, if you don't measure up, you may be sent home to change clothes - without pay for the time you've missed.  Now, to be fair, the Daily Journal is a legal newspaper, and law firms - along with the courts - remain kind of a bastion for traditional business attire.

Thomas: And that means jackets and ties for men...?

Lacter: ...and skirt suits and business dresses for women.  It's the same deal for many offices in New York and Chicago.  Matter of fact, dressing down is still not especially popular in many parts of the country, according to a new survey I came across.  More than half of the respondents say it suggests an employee doesn't have respect for the workplace.  In other words, not a team player.

Thomas: But L.A. has this huge creative community where jeans and tee-shirts are almost part of the uniform.

Lacter: Yeah, the only people wearing suits at these places are the high-level executives who are actually called "suits."  This has been true in Hollywood for years, but now you're seeing it with the growth of tech companies.  Imagine how confusing it must be for an attorney who wears the standard business uniform, and who has one of these companies as his client.  And, maybe that's the point - there is no single workplace culture, even within the companies themselves.

Thomas: Is being comfortable just not on the radar at these places?

Lacter: Well, not to pick on the Daily Journal, but so what if someone who is stuck in front of a computer all day wants to be a little more comfortable in jeans?  Will the world as we know it come to a halt?  You know, the workplace is far different than it was even 10 years ago.  People are doing their jobs in all sorts of ways, whether it's working from home, or as independent contractors.  And, this is really all about common sense - so, maybe it's time the stick-in the-muds realized as much.

Thomas: Attire aside, how is the workplace itself changing?

Lacter: Some of those downtown law firms have been cutting back, which means that they don't need as much space.  Not every attorney needs a giant office.  Same with the downtown accounting firms - when folks do go to work, the office may include a fancy kitchen, a ping pong table, workstations that double as treadmills, a place to do yoga or even to take a nap.

Thomas: All this is supposed to boost productivity...

Lacter: ...which it probably does, though you do have to wonder whether having a yoga room really enhances output, or is just a way of keeping employees from not taking a job somewhere else.  My favorite perk, and I say that facetiously, is the office kegerator, which not only seems like a dumb idea, but a great way for a company to get sued if somebody has one too many.

Thomas: Quickly Mark, any news in the dispute between CBS and Time Warner Cable?

Lacter: Not good news.  Time Warner Cable offered what it said were two possible solutions to the standoff, but CBS has came back and called it a sham.  Time Warner Cable subscribers have been without CBS programming since Friday, which is already going on longer than analysts had first expected.  The fight is over re-transmission fees - the amount of money that a programmer receives from a distributor- in this case, Time Warner Cable.  CBS apparently wants a big increase, and Time Warner Cable doesn't want to pay.

The positional change of nitro­gen-7 of the RNA constituent guanosine to the bridgehead position-5 leads to the base-modified nucleoside 5-aza-7-de­aza­guanosine. Contrary to guanosine, this mol­ecule cannot form Hoogsteen base pairs and the Watson–Crick proton donor site N3—H becomes a proton-acceptor site. This causes changes in nucleobase recognition in nucleic acids and has been used to construct stable `all-purine' DNA and DNA with silver-mediated base pairs. The present work reports the single-crystal X-ray structure of 7-iodo-5-aza-7-de­aza­guanosine, C10H12IN5O5 (1). The iodinated nucleoside shows an anti conformation at the glycosylic bond and an N conformation (O4'-endo) for the ribose moiety, with an anti­periplanar orientation of the 5'-hy­droxy group. Crystal packing is controlled by inter­actions between nucleobase and sugar moieties. The 7-iodo substituent forms a contact to oxygen-2' of the ribose moiety. Self-pairing of the nucleobases does not take place. A Hirshfeld surface analysis of 1 highlights the contacts of the nucleobase and sugar moiety (O—H⋯O and N—H⋯O). The concept of pK-value differences to evaluate base-pair stability was applied to purine–purine base pairing and stable base pairs were predicted for the construction of `all-purine' RNA. Furthermore, the 7-iodo substituent of 1 was functionalized with benzo­furan to detect motional constraints by fluorescence spectroscopy.

Smokers who are exposed to radon appear to be at even greater risk for lung cancer, because the effects of smoking and radon are more powerful when the two factors are combined, says a new report by a committee of the National Research Council.

Reducing one of the nations leading causes of death and injury – medical errors – will require rigorous changes throughout the health care system, including mandatory reporting requirements.

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.

Research to date on the effect of capital punishment on homicide rates is not useful in determining whether the death penalty increases, decreases, or has no effect on these rates, says a new report from the National Research Council.

Over 32,000 people have died from the new coronavirus in the United Kingdom, according to the Office for National Statistics, marking the first time in the pandemic that it has led Europe in the number of deaths.

The country has surpassed Italy in COVID-19 deaths. The U.S. still leads the world in the highest number of coronavirus deaths; over 70,270 had died from the disease as of Tuesday.

The number of total deaths recorded in the U.K. is "higher than we would wish, I think is all I can say," Angela McLean, chief scientific adviser of Ministry of Defence said during the country's press briefing Tuesday.

McLean also emphasized that deaths in U.K. care homes have been steadily rising and said the trend was something the country "need[s] to get to grips with."

"I don't think we'll get a real verdict on how well countries have done until the pandemic is over," British Foreign Secretary Dominic Raab said Tuesday. "And particularly until we have comprehensive international data on all causes of mortality."

Since different countries collect and report coronavirus data using different methods, the comparisons between regions are not perfect. As more time passes and more tests are conducted and more data comes in, coronavirus death rates will become more precise.

The peak in deaths comes as other European countries, including Italy and Spain, are easing shelter-in-place restrictions, while U.K. Prime Minister Boris Johnson is expected to modify Britain's orders in the next week.
