A total of 15,25,631 tests have been conducted so far across 332 government and 121 private laboratories.

Using the typical WC–Co cemented carbide as an example, the interactions of dislocations within the ceramic matrix and the binder metal, as well as the possible cooperation and competition between the matrix and binder during deformation of the nanocrystalline cermets, were studied by molecular dynamics simulations. It was found that at the same level of strain, the dislocations in Co have more complex configurations in the cermet with higher Co content. With loading, the ratio between mobile and sessile dislocations in Co becomes stable earlier in the high-Co cermet. The strain threshold for the nucleation of dislocations in WC increases with Co content. At the later stage of deformation, the growth rate of WC dislocation density increases more rapidly in the cermet with lower Co content, which exhibits an opposite tendency compared with Co dislocation density. The relative contribution of Co and WC to the plasticity of the cermet varies in the deformation process. With a low Co content, the density of WC dislocations becomes higher than that of Co dislocations at larger strains, indicating that WC may contribute more than Co to the plasticity of the nanocrystalline cermet at the final deformation stage. The findings in the present work will be applicable to a large variety of ceramic–metal composite materials.

Researchers are scrambling to find effective treatments for COVID-19, which has infected more than 1 million people around the word.

When it comes to COVID-19 testing, questions remain about which of the tests available are reliable, how much testing is needed, and how to ensure access to testing. The latest COVID-19 Conversations webinar explored the challenges ahead.

All five members of the Los Angeles County Board of Supervisors have signed a letter imploring California Gov. Jerry Brown to intervene in the state’s handling of contamination around the Exide Technologies plant in Vernon.

The letter criticizing the state’s “piecemeal approach to an urgent environmental hazard” comes as workers paid for by Exide are removing lead-contaminated topsoil from two homes near the intersection of Olympic and Indiana avenues in L.A. 

Signed Tuesday, the letter asks for “guaranteed state funding to immediately begin testing” at 37 more homes also sampled, but to less specific degrees, during November 2013. In the words of the board, “further testing and remediation of the other 37 homes has not been confirmed and may not begin until at least October 2014 because Exide has not yet agreed to comply with DTSC directives issued last March.”

The supervisors also say the state has “reneged” on its commitments to test for lead inside the homes as well as outside.

The Department of Toxic Substances Control says that the two homes workers are at this week will be cleaned inside and out — even without indoor testing.  The DTSC’s Rizgar Ghazi said Monday that crews will use HEPA filters, vacuums and shampooing equipment on “basically any flat surface” inside the two residences.

As of Tuesday afternoon, L.A. County has at least 1,314 deaths and 27,836 confirmed cases of coronavirus.

New confirmed infections per day in the U.S. exceed 20,000, and deaths per day are well over 1,000,000 according to figures from Johns Hopkins University. And public health officials warn that the failure to flatten the curve and drive down the infection rate in places could lead to many more deaths — perhaps tens of thousands — as people are allowed to venture out and businesses reopen. From the marbled halls of Italy to the wheat fields of Kansas, health authorities are increasingly warning that the question isn’t whether a second wave of coronavirus infections and deaths will hit, but when — and how badly. President Donald Trump said his COVID-19 task force would keep working but focus more on rebooting the economy. According to the Orange County Register, more OC beaches received approval to open with limited hours.

To safely phase out social distancing measures, the U.S. needs more diagnostic testing for the coronavirus, experts say. But how much more?

The Trump administration said on April 27 the U.S. will soon have enough capacity to conduct double the current amount of testing for active infections. The country has done nearly 248,000 tests daily on average in the last seven days, according to the nonprofit Covid Tracking Project. Doubling that would mean doing around 496,000 a day.

Will that be enough? What benchmark should states try to hit?

One prominent research group, Harvard's Global Health Institute, proposes that the U.S. should be doing more than 900,000 tests per day as a country. This projection, released Thursday, is a big jump from its earlier projection of testing need, which was between 500,000 and 600,000 daily.

Harvard's testing estimate increased, says Ashish Jha, director of the Global Health Institute, because the latest modeling shows that the outbreak in the U.S. is worse than projected earlier.

"Just in the last few weeks, all of the models have converged on many more people getting infected and many more people [dying]," he says.

But each state's specific need for testing varies depending on the size of its outbreak, explains Jha. The bigger the outbreak, the more testing is needed.

Thursday Jha's group at Harvard published a simulation that estimates the amount of testing needed in each state by May 15. In the graphic below, we compare these estimates with the average numbers of daily tests states are currently doing. (Jump to graphic)

Two ways to assess whether testing is adequate

To make their state-by-state estimates, the Harvard Global Health Institute group started from a model of future case counts. They calculated how much testing would be needed for a state to test all infected people and any close contacts they may have exposed the virus. (The simulation estimates testing 10 contacts on average.)

"Testing is outbreak control 101, because what testing lets you do is figure out who's infected and who's not," Jha says. "And that lets you separate out the infected people from the non infected people and bring the disease under control."

This approach is how communities can prevent outbreaks from flaring up. First, test all symptomatic people, then reach out to their close contacts and test them, and finally ask those who are infected or exposed to isolate themselves.

Our chart also shows another testing benchmark for each state: the ratio of tests conducted that come back positive. Communities that see around 10% or fewer positives among their test results are probably testing enough, the World Health Organization advises. If the rate is higher, they're likely missing a lot of active infections.

What is apparent from the data we present below is that many states are far from both the Harvard estimates and the 10% positive benchmark.

Just nine states are near or have exceeded the testing minimums estimated by Harvard; they are mostly larger, less populous states: Alaska, Hawaii, Montana, North Dakota, Oregon, Tennessee, Utah, West Virginia and Wyoming.

Several states with large outbreaks — New York, Massachusetts and Connecticut among others — are very far from the minimum testing target. Some states that are already relaxing their social-distancing restrictions, such as Georgia, Texas and Colorado, are far from the target too.

Jha offers several caveats about his group's estimates.

Estimates are directional not literal

Researchers at the Global Health Initiative at Harvard considered three different models of the U.S. coronavirus outbreak as a starting point for their testing estimates. They found that while there was significant variation in the projections of outbreak sizes, all the models tend to point in the same direction, i.e. if one model showed that a state needed significantly more testing, the others generally did too.

The model they used to create these estimates is the Youyang Gu COVID-19 Forecasts, which they say has tracked closely with what's actually happened on the ground. Still the researchers caution, these numbers are not meant to be taken literally but as a guide.

If social distancing is relaxed, testing needs may grow

The Harvard testing estimates are built on a model that assumes that states continue social distancing through May 15. And about half of states have already started lifting some of those.

Jha says, that without the right measures in place to contain spread, easing up could quickly lead to new cases.

"The moment you relax, the number of cases will start climbing. And therefore, the number of tests you need to keep your society, your state from having large outbreaks will also start climbing," warns Jha.

Testing alone is not enough

A community can't base the decision that it's safe to open up on testing data alone. States should also see a consistent decline in the number of cases, of two weeks at least, according to White House guidance. If their cases are instead increasing, they should assume the number of tests they need will increase too.

And Jha warns, testing is step one, but it won't contain an outbreak by itself. It needs to be part of "a much broader set of strategies and plans the states need to have in place" when they begin to reopen.

In fact, his group's model is built on the assumption that states are doing contact tracing and have plans to support isolation for infected or exposed people.

"I don't want anybody to just look at the number and say, we meet it and we're good to go," he says. "What this really is, is testing capacity in the context of having a really effective workforce of contact tracers."

The targets are floors not goals

States that have reached the estimated target should think of that as a starting point.

"We've always built these as the floor, the bare minimum," Jha says. More testing would be even better, allowing states to more rapidly tamp down case surges.

In fact, other experts have proposed the U.S. do even more testing. Paul Romer, a professor of economics at New York University proposed in a recent white paper that if the U.S. tested every resident, every two weeks, isolating those who test positive, it could stop the pandemic in its tracks.

Jha warns that without sufficient testing, and the infrastructure in place to trace and isolate contacts, there's a real risk that states — even those with few cases now — will see new large outbreaks. "I think what people have to remember is that the virus isn't gone. The disease isn't gone. And it's going to be with us for a while," he says.

The NFL said Wednesday that its new performance-enhancing drug policy will allow the Broncos' Wes Welker and two other suspended players to return to the field this week.

The deal with the players association also adds human growth hormone testing, ending several years of wrangling between the league and the union.

Welker, Dallas Cowboys defensive back Orlando Scandrick and St. Louis Rams wide receiver Stedman Bailey had been suspended for four games.

Under the new rules, players who test positive for banned stimulants in the offseason will no longer be suspended. Instead, they will be referred to the substance abuse program.

The league and union are also nearing an agreement on changes to the substance abuse policy. That could reduce Cleveland Browns receiver Josh Gordon's season-long ban.

Testing for HGH was originally agreed upon in 2011, but the players had balked at the science in the testing and the appeals process for positive tests. Under the new deal, appeals of positive tests in the PED program will be heard by third-party arbitrators jointly selected by the NFL and union. Appeals will be processed more expeditiously under altered procedures

Testing should begin by the end of the month.

The new rules also change the length of suspensions. Previously, all first-time violations of the performance-enhancing drug policy resulted in at least a four-game suspension.

Now, use of a diuretic or masking agent will result in a two-game suspension. The punishment for steroids, in-season use of stimulants, HGH or other banned substances is four games. Evidence of an attempt to manipulate a test is a six-game suspension.

A second violation will result in a 10-game ban, up from a minimum of eight games. A third violation is at least a two-year suspension. Before, the ban was at least a year.

The long-lasting and negative effects of intensive farming on soils persist even where complex animal communities have been reintroduced to the soil in attempt to restore the natural balance, according to a recent study. The findings highlight the possible effects of historical land use on soils' ability to deliver ecosystem services.

Several barriers to upgrading existing social housing with innovative energy systems (IES) have been identified by a study of eight large-scale renovation projects in the Netherlands. These include a lack of trust between stakeholders, opposition from tenants on grounds of increased costs or delays, or poor experience with previous energy projects.

Despite the substantial impacts warming and drought can have on soil bacteria and fungi, these are not sustained if external conditions re-stabilise, a new study suggests. Small-scale experiements in five countries across Europe to show that even if warming and droughts continued for over a decade, there were no lasting effects on key properties of soils, such as growth rates, when the soils were allowed to re-stabilise in a laboratory over seven days.

Recycling green waste as compost could match the environmental benefits of converting it into renewable energy, in terms of CO₂ savings, according to new German research. It suggests that the two forms of waste management should be seen as complementary and both should receive subsidies.

Scientists have tested the behaviour of biodegradable plastics in managed composting and anaerobic conditions, as well as under simulated environmental conditions, such as in seawater or soil. This study found that blending different types of biodegradable plastics may open up new opportunities in relation to their end-of-life treatment — notably the potential to make one of the world’s best-selling biodegradable plastics, polyactic acid (PLA), home-compostable by blending it with another polymer (polycaprolactone — PCL). However, the researchers were also concerned that most materials tested could still cause plastic pollution as they failed to biodegrade sufficiently — and, in some cases, not at all, in particular, in soil and the marine environment.

A team of Carnegie scientists has discovered three giant planets in a binary star system composed of stellar ''twins'' that are also effectively siblings of our Sun. One star hosts two planets and the other hosts the third. The system represents the smallest-separation binary in which both stars host planets that has ever been observed. The findings, which may help explain the influence that giant planets like Jupiter have over a solar system's architecture, have been accepted for publication in The Astronomical Journal.

A new analysis of temperate forests has estimated that, on average, tree-felling and the removal of tree biomass reduces carbon levels in the soil by 8 per cent. The reduction is greatest in the forest floor layer where about 30 per cent of carbon is lost.

Bats can adapt to certain changes in habitat that threaten their preferred roosting sites. A new study from Poland shows that bats will widen their criteria for selecting roosting sites if forest management practices limit their preferred sites. However, experts recommend that small patches of old growth forest suitable for bat roosting are maintained as the bats in this study did not adapt to young woodland.

A recent study has assessed how the choice and cultivation of native and introduced pine tree species affects the impact of insect pests and fungal diseases in Spanish plantations. Native maritime pine trees appeared to be more susceptible to insect attack, whilst non-native Monterey pines were more likely to suffer from fungal attacks. Thinning trees also had differing effects on reducing the effects of pests, depending on the tree species.

Illegal timber imports into the EU were between 8 and 18 million m³ in 2009, representing 6-13% of total imports, new research suggests. Although figures for illegal logging are associated with high uncertainties, the authors claim that these figures provide the best available estimates for policy and decision makers.

Collecting, or ‘harvesting’ rainwater may help society cope with a number of problems, such as water shortages, flooding and the degradation of urban streams. Urban roofs make up about half of the total sealed surface (‘unnatural’ surfaces, which cover over natural surfaces, such as soil) in cities and contribute the most to stormwater run-off, which could be harvested for other purposes. To maximise this potential, it is useful to know which type of roof can harvest the greatest amount of good quality water.

Researchers have developed a new model to estimate the impact of harvesting wild species and land use change on biodiversity. Unlike previous models, it considers the indirect effect of harvesting or pest control on landscape structure through reducing the variety of species.

Farmland birds like skylarks are attracted to nest in agricultural grassland, but repeated harvesting for silage causes most nests to fail. This study showed that skylark breeding success in silage was too low to sustain local populations. The researchers say that grass silage is a hostile environment for breeding skylarks and conservation efforts should focus on making other parts of the landscape more attractive and productive for nesting birds.

Wastewaters from fruit-packaging plants may contain preservative chemicals. When spread onto fields, these wastewaters affect the way soil microbes cycle nitrogen, new research has found. Although this may impair crop growth, according to the authors, the results could also lead to the development of new substances that reduce nitrate run-off from agricultural land.

Danish researchers have recently revealed that crop harvesting can release high levels of Alternaria fungal spores, affecting air quality locally and, occasionally, over long distances. The fungus is known to trigger human allergic reactions, and the study calls for improved monitoring and forecasting of airborne fungal spores.
