Update 1:04 p.m. Goodell: 'Same mistakes can never be repeated'

Commissioner Roger Goodell says the NFL wants to implement new personal conduct policies by the Super Bowl. At a news conference Friday, Goodell made his first public statements in more than a week about the rash of NFL players involved in domestic violence. He did not announce any specific changes, but said he has not considered resigning.

"Unfortunately, over the past several weeks, we have seen all too much of the NFL doing wrong," he said. "That starts with me."

The league has faced increasing criticism that it has not acted quickly or emphatically enough concerning the domestic abuse cases.

The commissioner reiterated that he botched the handling of the Ray Rice case.

"The same mistakes can never be repeated," he said.

Goodell now oversees all personal conduct cases, deciding guilt and penalties.

He said he believes he has the support of the NFL's owners, his bosses.

"That has been clear to me," he said.

The Indianapolis Colts' Darius Butler was among those who tweeted criticism of the press conference:

The commissioner and some NFL teams have been heavily criticized for lenient or delayed punishment of Rice, Adrian Peterson and other players involved in recent domestic violence cases. Less than three weeks into the season, five such cases have made headlines, the others involving Greg Hardy, Ray McDonald and Jonathan Dwyer.

Vikings star running back Peterson, Carolina defensive end Hardy and Arizona running back Dwyer are on a special commissioner's exemption list and are being paid while they go through the legal process. McDonald, a defensive end for San Francisco, continues to practice and play while being investigated on suspicion of domestic violence.

As these cases have come to light, such groups as the National Organization of Women and league partners and sponsors have come down hard on the NFL to be more responsive in dealing with them. Congress also is watching to see how the NFL reacts.

In response to the criticism, the NFL announced it is partnering with a domestic violence hotline and a sexual violence resource center.

Goodell also said in a memo to the clubs late Thursday that within the next 30 days, all NFL and team personnel will participate in education sessions on domestic violence and sexual assault. The memo said the league will work with the union in providing the "information and tools to understand and recognize domestic violence and sexual assault."

The league will provide financial, operational and promotional support to the National Domestic Violence Hotline and the National Sexual Violence Resource Center.

12:07 p.m. Roger Goodell to break silence on domestic abuse and the NFL

Roger Goodell will make his first public statements in more than a week about the rash of NFL players involved in domestic violence when he holds a news conference Friday.

The NFL commissioner will address the league's personal conduct policy. The league has faced increasing criticism it has not acted quickly or emphatically enough concerning the domestic abuse cases.

His last public appearance was at a high school in North Carolina on Sept. 10.

The league will provide financial, operational and promotional support to the National Domestic Violence Hotline and the National Sexual Violence Resource Center.

"These commitments will enable both the hotline and NSVRC to help more people affected by domestic violence and sexual assault," Goodell said in the memo.

The National Domestic Violence Hotline provides domestic violence victims and survivors access to a national network of resources and shelters. It is available 24 hours a day, seven days a week in 170 languages. Goodell noted that the hotline received 84 percent more calls from Sept. 8-15, and the organization said more than 50 percent of those calls went unanswered because of lack of staff.

"The hotline will add 25 full-time advocates over the next few weeks that will result in an additional 750 calls a day being answered," he said.

NSVRC supports sexual violence coalitions across the United States. The NFL's initial support will be directed toward state coalitions to provide additional resources to sexual assault hotlines.

The Supreme Court has temporarily put on hold the release of redacted grand jury material from the Russia investigation to a House panel.

The Trump administration is trying to block the release.

Last October, a district court judge ruled the Justice Department had to turn over the materials, which were blacked out, from former special counsel Robert Mueller's report into Russian interference in the 2016 election.

An appeals court upheld the decision, but the Trump administration, hoping to keep the evidence secret, appealed to the Supreme Court.

Chief Justice John Roberts' order temporarily stops the process. Lawyers for the House Judiciary Committee have until May 18 to file their response to the Justice Department's attempts to keep the materials from the House panel.

The Justice Department had until Monday to turn over the material following the appeals court order. But on Thursday, the Trump administration asked the Supreme Court to block Congress from seeking it, saying, "The government will suffer irreparable harm absent a stay."

In a sign of increased desire of professionals to work remotely, the successful Santa Monica shared workspace Cross Campus is opening a second location in Pasadena later this month, and the company hopes to open eight others in Southern California and beyond in the next two years. 

Dubbed by one user as  the “nerve center” of the Silicon Beach tech scene, Cross Campus opened its membership-based workspace facility in Santa Monica in 2012.   

But co-founder Ronen Olshansky said the shared workspace phenomenon isn't limited to coders. 

"Fewer and fewer people are making the traditional drive into the corporate office," Olshansky said. "They're working remotely as professionals, going off on their own as freelancers, or they're starting their own companies as entrepreneurs."  

A forecast from Forrester Research says that 43 percent of workers will telecommute by 2016, compared to estimates of about a quarter of the workforce telecommuting last year. 

Olshansky said that, for many people, working from home or in a coffee shop isn't productive. 

That's led shared workspaces to pop up in Los Angeles, Culver City and Santa Monica. Among them: Maker City L.A., WeWork, NextSpace, Coloft and Hub LA.  

Los Angeles-based tech investor David Waxman said these kind of shared spaces are crucial for the early stages of tech ventures.

"When you’re just starting out, and capital is very scarce, having not to commit to an entire office but having part of an office is very important," Waxman said.  “There comes a collective energy when a bunch of entrepreneurs get together in the same space, even if they’re not working on the same project."

And he said Pasadena is a good choice for a shared workspace.

"It is the home of Caltech, the Arts Center, and IdeaLab — probably the world’s first tech incubator — started there," he said.

But he said the need isn't limited to Pasadena.

"In Silver Lake, in South Pasadena, in Glendale, you see a lot of little pockets of  people getting together, and as soon as there’s a critical mass, we’ll see co-working spaces like Cross Campus come into being," said Waxman, who named his investment firm TenOneTen after the two freeways that connect Santa Monica and the Westside to Pasadena. 

Alex Maleki of IdeaLab in Pasadena is happy a well-known company is opening up in his city. 

"Anything that helps attract talent and capital to the region," Maleki said, "is absolutely fantastic."

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."

Tradeshift, a supply...

There is a common assumption that plant species are more inclined to thrive in a non-native community than a native one, sometimes becoming 'invasive'. However, this behaviour is likely to be quite unusual and invasive alien plants are actually an important exception, according to a new study. Much can be learned from the population of a species 'at home' and should be included in official assessment criteria.

Removing sediment from harbour beds to allow ships to enter can significantly accelerate coastal erosion, the gradual wearing away of land by the sea. A new study highlights this damage and identifies a compensation strategy used in an Italian harbour to mitigate coastal erosion as a good example of effective Integrated Coastal Zone Management (ICZM).

Bycatch (species caught unintentionally in fisheries) in some commercial marine fisheries is the main cause of death in some populations of seabirds, sea turtles, marine mammals, sharks and fish. New research has revealed that bycatch from tuna fishing can be reduced by using better equipment, without compromising industry profits. However, significant policy efforts are needed to monitor bycatch and enforce more sustainable fishing practices.

A new study highlights the positive effects of plants and trees in cities. Urban green areas provide shade and reduce temperature fluctuations, bringing average temperatures down, while covering roofs with plants, rather than black roofs, reduces the energy required to heat and cool buildings.

A recent study has assessed the costs and effectiveness of reducing phosphorus pollution for lakes in Scotland, UK, to achieve good ecological status as required by the EU???s Water Framework Directive (WFD). It was found that phosphorus in 72% of the lake area in Scotland could be mitigated at a cost of ??5.7 million (???7 million) per year, which is considered a proportionate or reasonable cost given the resulting social benefits.

Heat waves are predicted to become more frequent under climate change, and are likely to be particularly severe in cities and towns due to the Urban Heat Island effect (UHI). A recent UK study of UHI mitigation strategies has demonstrated that even a small urban river can result in a cooling effect of 1??C during temperatures higher than 20??C, and that these cooling effects can be improved by careful urban design of the surrounding areas.

Researchers have found that ocean acidification leads to changes in the ways that clownfish normally respond to sound. As many species rely on hearing for orientation, habitat selection, avoiding predators and communication, ocean acidification could compromise auditory behaviour crucial for survival.

A recent study has described a simple method to screen the toxicity of materials used in consumer products. Using utility meter products as examples, the study found, for example, that stainless steel and polyvinyl chloride (PVC) had high toxicity potentials and suggests less toxic, but equally effective and priced, alternatives that could be used instead.

Green roofs have the potential to significantly reduce road traffic noise in the urban environment, according to a new study. The results suggest that greening of roofs and walls with materials suitable for growing plants softens the urban environment keeping sound levels low, whereas hard, manmade structures tend to amplify traffic noise.

Green roofs can cool buildings in summer and prevent heat loss in winter. A new study suggests, however, that in the warm climates of southern Europe the additional cost of watering means that 'cool roof coatings??? may be more cost effective.

Trees form a valuable part of green infrastructure in cities by helping reduce surface water runoff, recent research finds. Together with grassy areas, significant reductions in surface water flows can be achieved by planting trees, reducing the risk of floods.

Wealthier nations protect biodiversity no better than poorer nations, suggests new research. The study found no link between national GDP and the effectiveness of countries at conserving the species for which they have responsibility.

As 3D printing, also known as additive manufacturing (AM), begins to replace conventional manufacturing, the environmental impacts of its implementation must be assessed. This study conducted a life cycle assessment (LCA) to investigate the environmental and resource implications of using AM to manufacture the metal parts of an engine in a light distribution truck. In the LCA, the impacts of both present and possible future states of AM technology were compared with current conventional manufacturing. The results suggest that there are potential environmental and resource benefits1 to AM technologies, but that these benefits rely on the achievement of a clean energy source and further technological development.

Polycyclic aromatic hydrocarbons (PAHs) are a large group of toxic molecules produced by forest fires, industrial processes and the incomplete combustion of fossil fuels. The airborne particles containing these molecules are often washed into watercourses, where they can persist. This study uses long-term monitoring data from the Elbe river, Saxony, Germany, to show how changes in PAH sources affect both the concentrations of these chemicals and the corresponding environmental risks. The researchers suggest that controlling PAHs is the best prevention of harm to aquatic and human health.

An early-warning system developed by researchers could help forest managers in Europe predict which trees are at greatest risk of bark- beetle infestation. The study looked at the probability of bark-beetle outbreaks on two important conifer-tree species in Slovenia: the Norway spruce (Picea abies) and silver fir (Abies alba). It found that high temperatures, and extreme weather linked to climate change — including droughts and ice storms — weakened trees, making them more vulnerable to attack by bark beetles.

Relatively simple, low-cost measures, such as insulating walls and installing solar collectors and efficient heaters for hot water can significantly reduce energy consumption in housing developments, according to a recent study from Portugal. Energy-efficient homes not only benefit the environment, but were found to potentially reduce residents’ energy bills by over half in an apartment block studied by the researchers.

A recent study has compared the environmental impact of a range of building materials. Energy consumption, carbon dioxide emissions and water demand can all be reduced by switching to renewable sources of energy, improving technologies and promoting eco-friendly alternative materials.

Increasing the use of recycled materials could substantially reduce the carbon footprint of plastic packaging, research suggests. A new study of the life-cycle of plastic trays has shown that increasing the proportion of recycled material could lead to a significant reduction of greenhouse gas emissions.

Microsoft Edge is now giving users the ability to hide those pesky browser notification dialog boxes that are commonly used by web sites to push their content, or even spam, on visitors. [...]

A new study from Denmark has indicated that a substantial proportion of farmers may place professional values above cost savings when making decisions about how much pesticide to use. This implies that agricultural policy should consider a broad array of policy instruments to reduce pesticide usage.

An early warning system to predict the overfishing of individual species, far in advance of severe population decline, has been developed by researchers. The ‘eventual threat index’ was applied by the researchers to historical data on tuna and billfish populations, and accurately predicted their current declines as early as the 1950s.

A fossil that has been in the collection of the Smithsonian's National Museum of Natural History since it was discovered in 1951 is today helping scientists piece together the evolutionary history of whales and dolphins, including the origins of the endangered South Asian river dolphin.

Scientists today announced the discovery of a new species of pterosaur from the Patagonia region of South America. The cranial remains were in an excellent state of preservation and belonged to a new species of pterosaur from the Early Jurassic. The researchers have named this new species 'Allkauren koi' from the native Tehuelche word 'all' for 'brain', and 'karuen' for 'ancient'.

Under pressure from rising food prices, many nations have begun to acquire large tracts of agricultural land in foreign countries, a practice known as ‘land grabbing’. New research has now quantified current levels of land grabbing and demonstrated that it is accompanied by concerning levels of ‘water grabbing’ which could affect water supply in the ‘grabbed’ countries.

Researchers have proposed a new indexing scheme to help decision-makers prioritise brownfield sites for redevelopment. The scheme scores potential sites according to socio-economic, smart growth and environmental dimensions. By giving users the flexibility to emphasise some aspects of development as more important than others, it can be adapted for use in different contexts.

There is a growing demand for new settlements in and around urban areas due to social, economic and population factors. However, this can lead to the loss of agricultural land and green spaces that provide essential ecosystem services and contribute to the wellbeing of local people. Several countries, such as the UK and Germany, have attempted to limit the growth of urban areas by encouraging the redevelopment of brownfield sites.

Researchers have developed a prototype system to predict the impact of storms on European coastlines. The MICORE Early Warning System aims to improve civil defence and coastal evacuation plans and could pave the way for an autonomous early warning system to save countless lives and protect infrastructure worldwide.

Effective flood-risk communications should include specific information on how householders can protect themselves and their property against flooding, a recent Dutch study concludes. The researchers’ evaluation of communication strategies also highlights an important role for social media in spreading messages about flood risk and protection.

Although the causes of Alzheimer's disease are still unknown, it is clear that the disease commences with progressive amyloid deposition in the brains of affected persons between ten and fifteen years before the emergence of initial clinical symptoms such as memory loss. Researchers have now been able to show that Aducanumab, a human monoclonal antibody, selectively binds brain amyloid plaques, thus enabling microglial cells to remove the plaques. A one-year treatment with the antibody, as part of a phase Ib study, resulted in almost complete clearance of the brain amyloid plaques in the study group patients. The results, which were realized by researchers at UZH together with the biotech company "Biogen" and the UZH spin-off "Neurimmune," have been published in the renowned science journal "Nature."

The use of herbicides on crops causes environmental concerns. A new French study assesses the performance of cropping systems to manage weeds and finds that these techniques could control arable weeds in the long-term and reduce reliance on herbicides.

Reducing meat and dairy consumption would help reduce greenhouse gas (GHG) emissions from farming. A recent study describes the "ecological leftovers" approach to reducing livestock-related GHGs, which assumes that a sustainable number of livestock can be calculated on the basis of available marginal land, unsuitable for other purposes, and available agricultural by-products, which could be used as feed.

Phosphorus is a major pollutant of surface waters, contributing to poor water quality. A recent study investigated best management practices to reduce the over-application of phosphorus and minimise phosphorus losses from agriculture in four regions across Europe and North America.

Adverse effects of climate change on agriculture will counteract any improvements in reducing levels of child malnutrition in the developing world, according to a new report, which calculates that twenty-five million more children will face malnutrition by 2050.

Natural predators of agricultural pests are influenced by the type and range of habitats within a farming landscape. A new study has developed an approach which predicts the risk of pest infestation and natural predation according to landscape features, to help land managers structure landscapes that encourage natural pest control.

Restoration of upland bog habitats by blocking drainage channels has caused concern among some sheep farmers that this will reduce the quality of grazing areas. However, UK researchers have shown that drainage does not encourage growth of plants favoured by sheep, nor do sheep use drained areas more. Therefore they conclude such restoration measures are unlikely to detrimentally affect sheep grazing.

'Feed the crop not the soil' is the message of a new review into sustainable phosphorus use. Currently, phosphorus fertiliser is applied to the soil, and plants then take it up through the roots. However, more precise nutrient management is needed on farms, the researchers say, so that the phosphorus is targeted at the crop just as it needs it.

Widespread use of antibiotics to prevent and treat infections in people and animals as well as for promoting growth in livestock is causing environmental contamination. A new study highlights the need for extra measures to reduce environmental pollution from antibiotics. Such pollution can increase the risk of diseases caused by bacteria that become resistant to antibiotics.

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.

Despite the health benefits they bring, the trees and shrubs in our cities can cause health problems for pollen allergy sufferers. Now, a study by Spanish researchers has proposed guidelines for urban planting to reduce the effects of pollen on city-dwellers.
