“The Trump administration on Thursday [January 23] signed its long-promised regulation to remove millions of miles of streams and roughly half the country’s wetlands from federal protection, the largest rollback of the Clean Water Act since the modern law was passed in 1972.
“The move delivers a major win for the agriculture, home building, mining, and oil and gas industries, which have for decades sought to shrink the scope of the water law that requires them to obtain permits to discharge pollution into waterways or fill in wetlands, and imposes fines for oil spills into protected waterways.
“Those industries had fiercely fought an Obama-era regulation that cemented broad protections for head water streams, which are at the beginning of the river network, as well as certain wetlands. …Donald Trump, whose golf courses and other businesses had fought with regulators over Clean Water Act permits, has lambasted that rule as ‘disastrous’ and his administration repealed it last year.
“Here are six things to know about the new regulation, known as the Navigable Waters Protection Rule:
1) It goes beyond overturning Obama to erase protections that have been in place for decades
“The Trump administration has made a point of rolling back environmental rules put in place by its predecessor, accusing the Obama administration of federal overreach. But the new regulation goes much beyond repealing the Obama-era rule, unwinding the previous rules that have been in place to protect head water streams and wetlands since the 1970s and ‘80s.
“‘President Trump’s administration wants to make our waters burn again,’ Earth justice attorney Janette Brimmer said in a statement, referring to the 1969 fire on the Cuyahoga River in Cleveland that served as a major impetus for passing the Clean Water Act. ‘This all-out assault on basic safeguards will send our country back to the days when corporate polluters could dump whatever sludge or slime they wished into the streams and wetlands that often connect to the water we drink.’
2) It drew complaints from EPA's own advisers
“The Trump administration issued the rule despite concerns raised by EPA’s outside scientific advisers, who issued a draft report in late December that said the proposed version of the rule was ‘in conflict with established science … and the objectives of the Clean Water Act.’ The criticism was particularly notable given that the majority of the board members were handpicked by the Trump administration.
“When the Obama administration issued its more expansive rule in 2015, it did so based on a massive scientific report that documented the importance of small streams to the health of downstream rivers and bays. In overturning that rule and issuing a far narrower one that would remove federal protections for waterways that don't flow regularly and wetlands that don't have an immediate surface water connection to larger waterways, the Trump administration has argued that it's a matter of policy rather than of science.
“‘This isn’t about what’s an important water body. All water is important. This is about what waters Congress intended the agency to regulate,’ a senior EPA official said on a call with reporters Thursday.
3) Half the country's wetlands could lose protection
“Wetlands, the in-between zone separating water and land, serve a crucial role in soaking up flood waters, filtering pollution and providing habitat to fish and wildlife. Despite a goal by President Ronald Reagan to have ‘no net loss’ of wetlands, the U.S. has drained or filled in the lion's share of its marshes and bogs, and is continuing on a downward trend.
“The new rule lifts federal protections for roughly half of the country's wetlands, according to the agency's own internal estimates Environmental groups say this would surely accelerate the trend of lost wetlands at a time when the changing climate makes their benefits all the more important.
4) Dry, Western states will see the biggest impact
“Waterways in arid regions of the country, particularly in the West, are likely to be among those most affected by the new rule, which removes federal protections for streams that flow only after rainfall. According to EPA, as much as 94 percent of Arizona’s waterways could lose Clean Water Act protection under the regulation, as well as 89 percent of Nevada's.
“The Trump administration argues that just because a waterway isn't federally regulated doesn't mean that it's not protected, since states can still set more expansive protections. ‘Many states already have a robust network of regulations that protect their state’s waterways,’ EPA Administrator Andrew Wheeler told reporters. But many states, including Arizona, have laws on the books that prevent them from regulating more stringently than the federal government and states have been cutting the budgets for their environmental agencies.

“The solution is for students to go on strike until our institutions agree to pay adjuncts a fair wage” - Peter Jacobs
“Universities, colleges and community colleges make heavy use of part-time professors and lecturers, known as ‘adjuncts.’ Chances are very good that if you’re a current college student, you’ve taken a class taught by an adjunct.
“Although they make up a large chunk of college instructors, adjuncts are paid only a tiny fraction of what full-time professors make, often with no benefits and no say in institutional decision-making. Adjunct professors may hold doctorates but are paid on average only $3,000 for each course that they teach. If (and this is a big if) an adjunct somehow manages to secure five courses to teach during the academic year, which is on par with (or exceeds) the load of a full-time professor, they could be bringing in a whopping $15,000 a year…
“Adjuncts fear that if they ask for a raise, they will just be replaced with someone else who is more desperate for work and less argumentative. Adjuncts are also often caught in a cruel catch-22, where they can’t afford to strike for higher pay because their current pay is so low that striking would leave them unable to pay rent or other living expenses.
“Historians Kristen Edwards and Kim Tolley sum up the current adjunct situation quite well in The Chronicle of Higher Education: ‘Many colleges claim to advance social justice or develop democratic communities, but few have acted on their own principles when it comes to giving adjunct faculty a living wage and a real voice in decision-making. Everyone who cares about the quality of higher education should demand they do so. Since the founding of the nation, the purpose of higher education has been to develop skilled, thoughtful citizens capable of contributing in meaningful ways to society. This purpose will never be realized with a professoriate composed predominantly of instructors who work without the protection of real academic freedom, and have no role in shared governance, no job security, no benefits, low wages, and no real hope of ever finding a full-time position.’
“Given that our institutions are uninterested in paying these professors what they are worth; given that they are uninterested in allowing adjuncts to participate in college decision-making; given that adjunct professors are in such a tenuous position that they are by and large unable to bargain; given that even successful bargaining brings modest gains at best, and given the staggering amount of money that students pay in tuition, the solution is for students to go on strike until our institutions agree to pay adjuncts a fair wage.
“[We should] argue that $12,000 a course would be much more on par with the value these professors provide. This should come with benefits, job security and participation in institutional decision-making.
“…[Remember]: These adjuncts create courses, give lectures, answer questions outside of class, spend hours grading, help thousands of students learn to think critically and to move toward a better future, while getting paid less than some people make working in the fast food industry. Maybe it’s time we do something for them. Do we care about fair pay? Do we care about fair benefits? Do we care about fair representation? Do we believe that our adjunct professors are worth more than $15,000 a year?
“If we do, occupy lecture halls. Get into the auditoriums. Take over the labs. Sleep in those weird tiny rooms for the upper-level classes that only fit 10 people. Bring mattresses, bring blankets, bring food, bring games, blast music. Make big signs. Bring call-and-response chants. Discuss injustice. Demand justice. Tell our friends at other colleges to do the same. Make a difference for the people who are helping us make a difference in the world” (Peter Jacobs at Press Herald).

“Alzheimer's disease has long been characterized by the buildup of two distinct proteins in the brain: first beta-amyloid, which accumulates in clumps, or plaques, and then tau, which forms toxic tangles that lead to cell death. But how beta-amyloid leads to the devastation of tau has never been precisely clear. Now a new study at the University of Alabama at Birmingham appears to describe that missing mechanism.
“The study details a cascade of events. Buildup of beta-amyloid activates a receptor that responds to a brain chemical called norepinephrine, which is commonly known for mobilizing the brain and body for action. Activation of this receptor by both beta-amyloid and norepinephrine boosts the activity of an enzyme that activates tau and increases the vulnerability of brain cells to it, according to the study, published in .
“Essentially, beta-amyloid hijacks the norepinephrine pathway to trigger a toxic buildup of tau, says Qin Wang, the study’s senior author and a professor of neuropharmacology in the department of cell, developmental and integrative biology at the University of Alabama at Birmingham.‘We really show that this norepinephrine is a missing piece of this whole Alzheimer’s disease puzzle,’ she says…”

"All of us have created and are creating the conditions in which omnicide is inevitable" by Danielle Celermajer
“As the full extent of the devastation of the Holocaust became apparent, a Polish Jew whose entire family had been killed, Raphael Lemkin, came to realise that there was no word for the distinctive crime that had been committed: the murder of a people. His life work became finding a word to name the crime and then convincing the world to use it and condemn it: genocide. Today, not only has genocide become a dreadful part of our lexicon. We recognise it as perhaps the gravest of all crimes.
“This time, though, we need to go much further. We need to understand that the responsibility for omnicide is various and layered. The role that those responsible play this time is almost always less direct, but its effect no less devastating. We are unlikely to identify anyone actively scheming the death of the five-hundred million wild animals whom we believe to have died in the first month of this summer’s Australian bushfires.
“We can identify the financial institutions that continue to invest in, and thereby prop up toxic industries, and who support the abovementioned media owners so as to protect themselves from accumulating stranded assets. We can identify the investors who use their financial and social capital to support politicians who will protect their financial interests. We can identify a corporate culture and a legal system, populated by lawyers, management consultants and financial analysts, that incentivise or even require companies to maximise short term shareholder profit and externalise costs to the future and the planet.
“None on this long list developed a specific intent to kill everything. But all of us have created and are creating the conditions in which omnicide is inevitable.

HILTON HEAD, N.C. (WJW) — An opossum is recovering after golfers beat her with their clubs.
According to the Wildlife Rehab of Greenville, Scarlett was beaten on Friday by golfers on Hilton Head Island, leaving her blind and with a broken jaw. Scarlett weighs only two pounds and still has her baby teeth.
A veterinarian is managing her care and believes she can recover, but a lengthy recovery process is expected. Officials do not know why the golfers beat her.
As rehabbers, the wildlife center says it has no authority to investigate the incident; however, they have filed a report with the Department of Natural Resources and trust they will investigate further. The rehab has also contacted the golf course about the incident.
Wildlife Rehab of Greenville reminds citizens that this incident should not reflect poorly on the golf course or the city of Hilton Head, stating that “this act is the sole responsibility of the sick person or persons who attacked this baby.”
The rehab center is accepting donations to help with Scarlett’s care.

“…For centuries, it was believed that disabled people like me were living under a curse that was inflicted by God. Well, I suppose it’s possible that I’ve upset someone up there, but I prefer to think that everything can be explained another way, by the laws of nature. If you believe in science, like I do, you believe that there are certain laws that are always obeyed. If you like, you can say the laws are the work of God, but that is more a definition of God than a proof of his existence…(26).
“I believe that the discovery of these laws has been humankind’s greatest achievement, for it’s these laws of nature — as we now call them — that will tell us whether we need a god to explain the universe at all. The laws of nature are a description of how things actually work in the past, present and future. In tennis, the ball always goes exactly where they say it will. And there are many other laws at work here too. They govern everything that is going on, from how the energy of the shot is produced in the players’ muscles to the speed at which the grass grows beneath their feet. But what’s really important is that these physical laws, as well as being unchangeable, are universal. They apply not just to the flight of a ball, but to the motion of a planet, and everything else in the universe. Unlike laws made by humans, the laws of nature cannot be broken — that’s why they are so powerful and, when seen from a religious standpoint, controversial too…(27-8).
“One could define God as the embodiment of the laws of nature. However, this is not what most people would think of as God. They mean a human-like being, with whom one can have a personal relationship. When you look at the vast size of the universe, and how insignificant and accidental human life is in it, that seems most implausible. I use the word ‘God’ in an impersonal sense, like Einstein did, for the laws of nature, so knowing the mind of God is knowing the laws of nature. My prediction is that we will know the mind of God by the end of this century…(28). I think the universe was spontaneously created out of nothing, according to the laws of science...(29).
“Despite the complexity and variety of the universe, it turns out that to make one you need just three ingredients. Let’s imagine that we could list them in some kind of cosmic cookbook. So what are the three ingredients we need to cook up a universe? The first is matter — stuff that has mass. Matter is all around us, in the ground beneath our feet and out in space. Dust, rock, ice, liquids. Vast clouds of gas, massive spirals of stars, each containing billions of suns, stretching away for incredible distances (29).
“The second thing you need is energy. Even if you’ve never thought about it, we all know what energy is. Something we encounter every day. Look up at the Sun and you can feel it on your face: energy produced by a star ninety-three million miles away. Energy permeates the universe, driving the processes that keep it a dynamic, endlessly changing place.
“So we have matter and we have energy. The third thing we need to build a universe is space. Lots of space. You can call the universe many things — awesome, beautiful, violent — but one thing you can’t call it is cramped. Wherever we look we see space, more space and even more space. Stretching in all directions…(30).
“As I was growing up in England after the Second World War, it was a time of austerity. We were told that you never get something for nothing. But now, after a lifetime of work, I think that actually you can get a whole universe for free. (31).
“The great mystery at the heart of the Big Bang is to explain how an entire, fantastically enormous universe of space and energy can materialize out of nothing. The secret lies in one of the strangest facts about our cosmos. The laws of physics demand the existence of something called ‘negative energy' (30-1).
“To help you get your head around this weird but crucial concept, let me draw on a simple analogy. Imagine a man wants to build a hill on a flat piece of land. The hill will represent the universe. To make this hill he digs a hole in the ground and uses that soil to dig his hill. But of course he’s not just making a hill — he’s also making a hole, in effect a negative version of the hill. The stuff that was in the hole has now become the hill, so it all perfectly balances out. This is the principle behind what happened at the beginning of the universe (32).
“When the Big Bang produced a massive amount of positive energy, it simultaneously produced the same amount of negative energy. In this way, the positive and the negative add up to zero, always. It’s another law of nature (32).
“So where is all this negative energy today? It’s in the third ingredient in our cosmic cookbook: it’s in space. This may sound odd, but according to the laws of nature concerning gravity and motion — laws that are among the oldest in science — space itself is a vast store of negative energy. Enough to ensure that everything adds up to zero (32).
“I’ll admit that, unless mathematics is your thing, this is hard to grasp, but it’s true. The endless web of billions upon billions of galaxies, each pulling on each other by the force of gravity, acts like a giant storage device. The universe is like an enormous battery storing negative energy. The positive side of things — the mass and energy we see today — is like the hill. The corresponding hole, or negative side of things, is spread throughout space (33).
“So what does this mean in our quest to find out if there is a God? It means that if the universe adds up to nothing, then you don’t need a God to create it. The universe is the ultimate free lunch (33).
“Since we know the universe itself was once very small — perhaps smaller than a proton — this means something quite remarkable. It means the universe itself, in all its mind-boggling vastness and complexity, could simply have popped into existence without violating the known laws of nature. From that moment on, vast amounts of energy were released as space itself expanded — a place to store all the negative energy needed to balance the books. But, of course, the critical question is raised again: did God create the quantum laws that allowed the Big Bang to occur? In a nutshell, do we need a God to set it up so that the Big Bang could bang? I have no desire to offend anyone of faith, but I think science has a more compelling explanation than a divine creator…(34).
“Imagine a river, flowing down a mountainside. What caused the river? Well, perhaps the rain that fell earlier in the mountains. But then, what caused the rain? A good answer would be the Sun, that shone down on the ocean and lifted water vapor up into the sky and made clouds. Okay, so what caused the Sun to shine? Well, if we look inside, we see the process known as fusion, in which hydrogen atoms join to form helium, releasing vast quantities of energy in the process. So far so good. Where does the hydrogen come from? Answer: The Big Bang. But here’s the crucial bit. The laws of nature itself tell us that not only could the universe have popped into existence without any assistance, like a proton, and have required nothing in terms of energy, but also that it is possible that nothing caused the Big Bang. Nothing...(34-5).
“Something very wonderful happened to time at the instant of the Big Bang. Time itself began. To understand this mind-boggling idea, consider a black hole floating in space. A typical black hole is a star so massive that it has collapsed in on itself. It’s so massive that not even light can escape its gravity, which is why it’s almost perfectly black. Its gravitational pull is so powerful, it warps and distorts not only light but also time. To see how, imagine a clock is being sucked into it. As the clock gets closer and closer to the black hole, it begins to get slower and slower. Time itself begins to slow down. Now imagine the clock as it enters the black hole — well, assuming of course that it could withstand the extreme gravitational forces– it would actually stop. It stops not because it is broken, but because inside the black hole time itself doesn’t exist. And that’s exactly what happened at the start of the universe…(35-7).
“As we travel back in time towards the moment of the Big Bang, the universe gets smaller and smaller and smaller, until it finally comes to a point where the whole universe is a space so small that it is in effect a single infinitesimally small, infinitesimally dense black hole. And just as with modern-day black holes, floating around in space, the laws of nature dictate something quite extraordinary. They tell us that here too time itself must come to a stop. You can’t get to a time before the Big Bang because there was no time before the Big Bang. We have finally found something that doesn’t have a cause, because there was no time for a cause to exist in. For me this means that there is no possibility of a creator, because there is no time for a creator to have existed in…(37-8).
“[I]t’s my view that the simplest explanation is that there is no God. No one created the universe and no one directs our fate. This leads me to a profound realization: there is probably no heaven and afterlife either. I think belief in an afterlife is just wishful thinking. There is no reliable evidence for it, and it flies in the face of everything we know in science. I think that when we die we return to dust. But there’s a sense in which we live on, in our influence, and in our genes that we pass on to our children. We have this one life to appreciate the grand design of the universe, and for that I am extremely grateful…(38).
“One day, I hope we will know the answers to all these questions. But there are other challenges, other big questions on the planet which must be answered, and these will also need a new generation who are interested and engaged, and have an understanding of science. How will we feed an ever-growing population? Provide clean water, generate renewable energy, prevent and cure disease and slow down global climate change? I hope that science and technology will provide the answers to these questions, but it will take people, human beings with knowledge and understanding, to implement these solutions. Let us fight for every woman and every man to have the opportunity to live healthy, secure lives, full of opportunity and love. We are all time travelers, journeying together into the future. But let us work together to make that future a place we want to visit. Be brave, be curious, be determined, overcome the odds. It can be done…”(21-2).
