Democrats and some Republicans are considering ways for the federal government to get money into people's pockets while the coronavirus is keeping much of the economy on ice.

Proposals for the next round of aid are being floated, and Democrats in the House are prepping another relief package as jobless claims continue to rise in the country. The Labor Department announced Friday that 20.5 million jobs were lost in April, pushing the overall unemployment rate to 14.7 %.

House Speaker Nancy Pelosi, D-Calif., hopes to release another bill, which is being crafted without the input of Republicans or the White House as early as next week.

"This is a reflection of the needs of the American people," Pelosi said Thursday. "We have to start someplace and, rather than starting in a way that does not meet the needs of the American people, want to set a standard."

The latest proposal from Sens. Kamala Harris, D-Calif., Bernie Sanders, I-Vt., and Ed Markey D-Mass., is a plan for the federal government to provide $2,000 a month for every individual earning less than $120,000, including children and other dependents. The draft legislation would extend the payments until three months after the public health emergency is lifted.

The proposal is a vast expansion on the recovery rebate program that sent a one-time payment of $1200 to every person earning less than $75,000 and an additional $500 for every child.

The trio of Democratic senators wants to make the payments, which would be available to every U.S. resident, retroactive to March. They didn't provide a cost estimate for the ambitious proposal, and it's unclear whether Senate leaders have an appetite for payments like these.

Official scorekeepers at the Congressional Budget Office estimate that the existing one-time $1200 payment program in the CARES Act package enacted in March could cost around $300 billion. Republican leaders have signaled concerns with the growing cost of the relief bills that have already passed.

Senate Majority Leader Mitch McConnell, R-Ky., has called for a pause on any new aid.

"Let's see what we are doing that is succeeding, what is not succeeding, what needs less, what needs more," McConnell told reporters in April. "Let's weigh this very carefully because the future of our country in terms of the amount of debt that we are adding up is a matter of genuine concern."

Not all Republicans agree. Sen. Josh Hawley, R-Mo., has introduced a comprehensive response plan that includes a proposal to cover 80 percent of payroll for companies that rehire workers and a bonus for the companies that take advantage of the program.

"The federal government should cover 80 percent of wages for workers at any U.S. business, up to the national median wage, until this emergency is over," Hawley wrote in an editorial in The Washington Post. "The goal must be to get unemployment down — now — to secure American workers and their families, and to help businesses get ready to restart as soon as possible."

Hawley's proposal would cap payments at the national median income level. The median income can be calculated in several different ways. Hawley told St. Louis Public radio the payments could be as high as $50,000. Other calculation set the figure at roughly $33,000, a figure many Democrats say is not sufficient in higher-cost areas like cities.

House Progressive Caucus co-chair Rep. Pramila Jayapal, D-Wash., has a separate version that would guarantee a worker's full salary up to $100,000 for three months. Jayapal's plan would automatically renew the payments on a monthly basis until consumer demand returns to pre-crisis levels.

The proposal has nearly two dozen co-sponsors but has not received an endorsement from party leadership.

Pelosi has not ruled out the possibility of including some minimum income payments in an upcoming coronavirus aid bill.

"We may have to think in terms of some different ways to put money in people's pockets," Pelosi said in an interview with MSNBC. "Let's see what works, what is operational and what needs other attention."

For the first time, Uber will guarantee drivers an hourly wage of $20 an hour in Los Angeles, or $26 during peak times.; Credit: David Ramos/Getty Images

To keep demand high during the slower winter months, the ridesharing service, Uber, has cut fares by 20 percent in 48 markets – including Los Angeles and Orange County.

The company says a trip from West Hollywood to downtown will now be around nine dollars, instead of $11.

When Uber lowered prices in the past to muscle out competitors like Lyft and taxi services, passengers loved it but drivers have complained it puts an unfair squeeze on them, complaining their already low take went even lower.

Uber stresses the fact cutting fares actually helps drivers because they get more business. In a blog post, the company points to data from Chicago where fares dropped 23 percent last month compared to December 2013 while drivers' income increased by 12 percent.

But drivers have been skeptical whether volume can make up for the price drop. The company's claim that New York city drivers earn a median of $90,766 a year has been refuted. Slate talked to New York UberX driver Jesus Garay in October:

“They say it doesn’t hurt the pocket of the drivers,” Garay says of the 20 percent fare cuts. “It does. Because it’s impossible with those numbers to be in business.”

The way drivers see it, ride volume can only increase so much in response to lower prices. Garay says that on average, a ride takes him 20 minutes from start to finish: five minutes to reach the pickup location, five to wait for the customer, and 10 to drive to the destination. For a trip of that length, Garay says he’ll make $10 or $11. “So if you’re busy, you’re going to make three rides in an hour,” he explains. 

Newly flush with a $40 billion valuation, Uber is now willing to put its money where its mouth is; For the first time, Uber will guarantee its partners – as it calls them -  an hourly wage of $20 an hour in Los Angeles, or $26 during peak times. (The guarantee comes with a few conditions: Drivers have to accept 90% of trips, average at least one trip per hour, and be online for 50 minutes of every hour worked)

The molecular mechanism used by many bacteria to kill neighboring cells has redundancy built into its genetic makeup, which could allow for the mechanism to be expressed in different environments, say researchers at Penn State and the University of Wisconsin-Madison. Their new study provides insights into the molecular mechanisms of competition among bacteria. "Many organisms, including humans, acquire bacteria from their environment," said Tim Miyashiro, a biochemist and molecular biologist at Penn State and the leader of the research team. "These bacteria can contribute to functions within the host organism, like how our gut bacteria help us digest food. We're interested in the interactions among bacteria cells, and between bacteria and their hosts, to better understand these mutually beneficial symbiotic relationships." Cells of the bioluminescent bacteria Vibrio fisheri take up residence in the light organ of newly hatched bobtail squid. At night, the bacteria produce a blue glow that researchers believe obscures a squid's silhouette and helps protect it from predators. The light organ has pockets, or crypts, in the squid's skin that provide nutrients and a safe environment for the bacteria. "When the squid hatches, it doesn't yet have any bacteria in its light organ," said Miyashiro. "But bacteria in the environment quickly colonize the squid's light organ." Some of these different bacteria strains can coexist, but others can't. "Microbial symbioses are essentially universal in animals, and are crucial to the health and development of both partners," says Irwin Forseth, a program director in the National Science Foundation's Division of Integrative Organismal Systems, which funded the research. "The results from this study highlight the role small genetic changes can play in microbe interactions. Increased understanding will allow us to better predict organisms' performance in changing environments."

Demonstration projects can represent a critical intermediate step between research and development (R&D) and large-scale commercialisation; yet many involving new sustainable technologies fail. In order to map the internal and external factors that enable or prohibit demonstration projects from reaching their goals, a case study of 21 projects was conducted. Qualitative data collected from funding applications and interviews were analysed to identify key themes. Based on these findings, the study proposes a process model outlining the key activities for setting up a new demonstration project.

A survey of over 600 private boats docked in marinas throughout the Mediterranean showed that 71% are carrying non-indigenous species. In certain cases, non-indigenous species can become ‘invasive’ and have enormous and long-lasting impacts on ecosystems. The findings suggest that a common monitoring strategy may be necessary to prevent further disruptions to natural ecosystems.

There is a need for greater harmonisation of the methods used to estimate the environmental impact of products, otherwise known as product category rules (PCRs). A new study has reviewed the development of PCRs and provided recommendations for better alignment.

A new concrete-reinforcement system, used by the LIFE INSU-SHELL1 project, replaces steel rods with non-corrosive textile structures to reduce the amount of concrete needed in construction. This nearly halves the global warming potential of traditional steel-reinforced concrete which is the largest producer of CO2 emissions in the building industry.

The public can help assess the human impact on wild birds through amateur ‘citizen science’ networks, according to new research. Scientists evaluated the suitability of data collected by amateur bird-watchers for long-term monitoring of European bird populations. Their findings suggest that citizen data may significantly improve the accuracy of existing official survey methods, as well as help increase public awareness of wild bird conservation.

Standardised methods of categorising environmental data are needed at European and international levels for effective international policies. A recent study has concluded that a European framework that harmonises environmental data at the continental scale corresponds well with national classification systems, although some modifications may be needed to capture small-scale regional variations.

Researchers are on a real-life search for what one calls "the ultimate Pokémon": Zenkerella, an elusive scaly-tailed squirrel that has never been spotted alive by scientists. However, biologists recently found three newly dead specimens that hint at how the "living fossil" has evolved over the past 49 million years.

New research has indicated that the design of a high proportion of agri-environmental policy measures in seven EU countries was based on common sense judgments about their possible impact. Only a sixth of the measures studied were based on well-tested quantitative models of their relationship to the environment.

Monitoring the effects of chemicals in the human body provides useful data for assessing and managing environmental risks to health, but it also raises ethical questions about how the results of such studies should be reported to participants. New research suggests that changes are needed to the research process to allow study participants to play a greater role in interpreting, disseminating and using the results.

Contrary to some established views, the local animal population is unlikely to be the major source of resistance diversity for Salmonella Typhimurium DT104 in humans in Scotland, according to a study. The researchers suggest that a broader approach to fighting antibiotic resistance is needed, which goes beyond focusing solely on curbing the use of antibiotics in domestic animal populations.

Published to mark the 20th anniversary of the Habitats Directive, this latest Thematic issue examines the challenges and successes in managing and restoring biodiversity in the Natura 2000 network.

New research has analysed some of the issues around the implementation of the EU's Environmental Noise Directive (END) by Member States. It demonstrated large differences in the way noise levels are calculated and geographically mapped between countries and called for more standardised and clearer guidelines.

Networks of wireless sensors could be used to monitor traffic noise. A new study shows that the wifi sensor systems, although slightly less accurate than precision noise monitoring systems, can provide detailed information, with dense coverage, about traffic noise over a longer period. Their low cost and low energy requirements make them particularly suitable and attractive for use by local authorities or even community groups.

Monitored natural attenuation (MNA) is a long-term, ‘hands-off’ approach to cleaning up contaminated land. New research has surveyed the current development of MNA in Europe and demonstrates a clear need for practitioners to systematically collect and learn from each other’s experiences with this form of brownfield remediation.

This Thematic Issue provides a flavour of recent work by scientists in the area of biodiversity monitoring to highlight both up-to-date approaches to conservation and evaluation, and how long-term monitoring data could be used more effectively in management and policy decisions.

In-depth soil information is increasingly required to achieve an array of environmental and economic goals. In particular, accurate estimates of soil carbon stocks are necessary to guide land-management practices and climate- related policymaking. To help meet this need, Australian scientists have developed a new sensing method to analyse cylindrical soil samples (soil cores), known as the Soil Condition ANalysis System (SCANS). By integrating a novel automated soil- core sensing system (CSS) with advanced statistical analytics and modelling, the SCANS provides a level of detail that is difficult to achieve with existing alternatives. SCANS is not only rapid, accurate and inexpensive1, but is likely to be a useful tool for farmers, land managers and policymakers, as the improved assessment of soil functions, structures and carbon stocks will facilitate more informed, sustainable decision-making.

The design and implementation of Payments for Ecosystem Services (PES) schemes could benefit from lessons learned from the management of common pool resources (CPR). By examining previous research into CPR, an international team of researchers has demonstrated that six sustainable management characteristics of CPRs also hold lessons for PES practitioners.

The environmental and economic costs of a selection of common crops have been determined by a new study, which hopes to improve agricultural sustainability assessments in Europe. The researchers used life cycle analysis on organically farmed tomatoes and pears, and intensively farmed wheat, apples, and lettuce to show the overall impact of agricultural methods.

How are Denmark, Finland, Iceland, Norway and Sweden moving towards renewable and lower-carbon energy use? A recent study suggests the key areas for progress, to ensure Nordic countries meet low carbon goals, include more renewable and decentralised electricity supply, the development of low-carbon transport systems, improved energy efficiency in building design and industrial use of carbon capture and storage.

Using open-access software and power saving technologies, researchers have developed an easily deployed, low-cost network for monitoring large areas of the Amazon rainforest. This Peruvian study shows that environmental information, such as soil moisture and rates of photosynthesis, can be recorded and uploaded to the internet without having to make repeated visits to remote areas.

‘Network bridging organisations’, such as farmer unions, Regional Nature Parks and Local Action Groups, promote cooperation between farmers, non-state collective actors and state actors under the Common Agricultural Policy. This study finds that farmers who have regular contact with these organisations show a higher commitment to long-term practice change. This could represent an opportunity to improve the effectiveness of payments for environmental services in Europe.

Effective regulation of genetically modified organisms (GMOs) calls for monitoring of the potential environmental risks. This study explored whether the German permanent soil monitoring programme could be a useful tool for this purpose. The researchers say the programme has potential to monitor the effects of GMOs on local soil communities, but that adaptations would be necessary.

Recent work in the coastal Mediterranean waters of the ‘Comunidad Valencia’ in Eastern Spain confirms that wastewater treatment plants (WWTPs) are a significant source of pollutants that need monitoring under the Water Framework Directive (WFD) and Priority Substances Directive. However, these substances also directly enter coastal waters from mixed urban, industrial and agricultural sources, creating a challenge for the development of control measures.

New research reveals how scientists can monitor water quality in European lakes using sensors mounted on satellites. The technique is a promising and cost-effective new tool to classify and monitor the ecological status of lakes more reliably under the Water Framework Directive (WFD).

New research has examined the impact of Produced Water (PW) discharges from a Norwegian oil field, using mussels to monitor the quality of the environment. The findings indicated the effectiveness of a bio-monitoring approach to study the chemical and biological influences of off-shore exploitation activities.

A better understanding of existing nitrate monitoring systems in European waters could greatly improve efforts to reduce nitrate pollution, a major cause of poor water quality, according to new research from Portugal.

Algal blooms in inland and marine waters could be detected and monitored more accurately in future, thanks to a new assessment method. Scientists have developed a new algorithm for sensors which identify emerging blooms of cyanobacteria based on the behaviour of light reflected by the algae’s pigment. Importantly, the algorithm may reduce uncertainty in estimations of algal concentrations by distinguishing between two different types of pigment.

Sustainable river management is increasingly informed by hydromorphological stream assessments — evaluations and classifications of stream conditions which account for both hydrological (the movement, distribution and quantity of water) and geomorphological (the processes and forms deriving from the interactions of water and sediment movement) features. In order to provide a more accurate and comprehensive assessment of river character and dynamics, scientists have developed three novel methods. Together, these tools represent a promising technique for conducting collaborative assessment and monitoring of river conditions in Europe.
