Trump NFL row: What have sports stars and team owners said?

LeBron James #23 of the Cleveland Cavaliers dunks the ball ahead of Kevin Durant #35 of the Golden State Warriors in Game 5 of the 2017 NBA Finals at ORACLE Arena on June 12, 2017 in Oakland, California
US President Donald Trump is embroiled in a row with leading figures in the sports world after he said NFL players who protested during the playing of the national anthem should be fired.
The president also received flak for criticising NBA star Stephen Curry in a tweet for not wanting to visit the White House with his championship-winning basketball team.
But who has spoken out, and what have they said?
Warning: This article contains language some readers may find offensive.

The NFL

League representatives, team owners, players' representatives and of course players themselves have all spoken out since President Trump unleashed a tirade on American Football players kneeling during the national anthem in protest at police violence against African-Americans.
Former San Francisco 49ers quarterback Colin Kaepernick became a lightning rod for criticism when he did just that last year, with several players since following suit.
"Wouldn't you love to see one of these NFL owners, when somebody disrespects our flag, to say, 'Get that son of a bitch off the field right now... he is fired?" Mr Trump asked a rally in Alabama.
NFL commissioner Roger Goodell released a statement saying "divisive comments like these demonstrate an unfortunate lack of respect".
NFL Players' Association president Eric Winston said Mr Trump's comments were "a slap in the face to the civil rights heroes of the past and present".
Twitter post by @realDonaldTrump
Meanwhile, Mr Kaepernick's mother, Teresa Kaepernick, tweeted: "Guess that makes me a proud bitch."
Owner of the San Francisco 49ers Jed York called the president's comments "callous and offensive" and "contradictory to what this great country stands for".
New England Patriots CEO Robert Kraft, a man who has previously calledMr Trump a "very good friend" and donated $1m to his inauguration according to the New York Times, said he was "deeply disappointed by the tone of the comments".
Eric Reid #35 and Colin Kaepernick #7 of the San Francisco 49ers kneel in protest during the national anthem prior to their NFL game against the Tampa Bay Buccaneers at Levi's Stadium on October 23, 2016
He said he supported players' right to "peacefully affect social change and raise awareness in a manner that they feel is most impactful".
Baltimore Ravens owner Steve Bisciotti said his players had influence and that management respected and supported them "100 percent".
Minnesota Vikings player Bishop Sankey tweeted: "It's a shame and disgrace when you have the president of the US calling citizens of the country sons of a bitches."
The Seattle Seahawks' Doug Baldwin said he believed "this will be a unifying moment for the sports world". His teammate Michael Bennett, who has been sitting out the national anthem in protest, tweeted: "My mom is a beautiful lady she has never been a bitch."
Meanwhile, New York Giants owners John Mara and Steve Tisch said the president had been "inappropriate, offensive and divisive".

Atlanta Falcons owner Arthur Blank called for "constructive dialogue", while Miami Dolphins owner Stephen Ross said his players who kneeled for the anthem were "smart young men of character" who "wanted to start a conversation".
Twitter post by @AtlantaFalcons
Twitter post by @MiamiDolphins
While some sports fans have expressed support for Mr Trump, some sports stars and team owners who have backed Trump, such as New York Jets boss Woody Johnson - a Trump campaign donor who was appointed as his ambassador to the UK - appear to have stayed out of the row.
The NBA
Cleveland Cavaliers all-time leading scorer LeBron James, seen as one of the best US basketball players ever, was one of the first to respond to the president's attack on Stephen Curry, named the NBA's top performer in 2015.
Mr Trump had tweeted: "Going to the White House is considered a great honor for a championship team. Stephen Curry is hesitating, therefore invitation is withdrawn!"
In response, Le Bron James, who publicly supported Hillary Clinton in the 2016 election, called him a "bum". "Going to White House was an honour until you showed up," he said.
Curry told a press conference that his beliefs were "cemented even further about how things in our country are going" after Mr Trump's comments.
Kobe Bryant, formerly of the LA Lakers but now retired, also tweeted a response.
Twitter post by @kobebryant
Curry's team, the Golden State Warriors, said it was clear they were not invited to the White House but that the team would visit Washington DC on its own "to celebrate equality, diversity, and inclusion".
Head coach Steve Kerr said Mr Trump's comments about the NFL players were "as bad as anything he has said".
NBA Commissioner Adam Silver said he was disappointed the team would not be visiting the White House as it would have been a "rare opportunity for these players to share their views directly with the president" but that he was "proud" of players.
Twitter post by @NBA

Major League Baseball (MLB)

On Saturday night, the Oakland Athletics' Bruce Maxwell became the first Major League Baseball player to kneel in protest during the national anthem, mimicking the gesture of protest started by Colin Kaepernick.
His father is in the military and he was born on an army base, US media report. He told a reporter he was "kneeling for people that don't have a voice".
His team soon after said it supported its players' "constitutional rights and freedom of expression".
Twitter post by @Athletics
The MLB has also released a statement, according to ESPN reporter Buster Olney.
He quoted it as saying: "Major League Baseball has a longstanding tradition of honouring our nation prior to the start of our games. We also respect that each of our players is an individual with his own background, perspectives and opinions. We believe that our game will continue to bring our fans, their communities and our players together.

Life first emerged in ‘warm little ponds’ almost as old as the Earth itself

Life first emerged in ‘warm little ponds’ almost as old as the Earth itself


567041.bin


Life on Earth began up to 4.5 billion years ago as carbon-rich meteors bombarded the planet and leached the essential elements into “warm little ponds”, according to new research.
It was in this nutrient-rich broth that the first self-replicating molecules, with the first genetic code for life, were born.
While the idea we are descended from something that emerged in “warm little ponds” was suggested by Charles Darwin in the 19th century, it has been challenged by claims it all started around hydrothermal vents in the ocean.
But, in a new paper in the journal Proceedings of the Academy of Sciences (PNAS), researchers described how they had constructed a “comprehensive model” proving Darwin’s idea was plausible.
The earliest genetic material is believed to have been ribonucleic acid or RNA, which every human has along with DNA. While DNA is like the “blueprint” of a cell, the RNA is involved in translating this code into proteins and has a number of other tasks in regulating processes in cells, including growth, ageing and death.
In the PNAS paper, the scientists wrote: “One of the most fundamental questions in science is how life first emerged on Earth. 
“Given its ubiquity in living cells and its ability to both store genetic information and catalyse its own replication, RNA probably formed the basis of first life.”

They pointed to fossil evidence of life dated to more than 3.7 billion years ago.
“Thus the RNA world would have developed on a violent early Earth undergoing meteoritic bombardment,” the researchers wrote.
“At that time, the atmosphere was dominated by volcanic gases, and dry land was scarce as continents were rising out of the global ocean.”

Their model suggested the first RNA polymers “likely appeared before 4.17 billion years ago” and possibly as long ago as 4.5 billion years. Planet Earth itself is thought to be about 4.54 billion years old.
If life is truly as old as this, it suggests a number of things.
One is that simple life is likely to be common in the universe as it can survive in hostile conditions. At the time, the Earth was not shielded by a protective layer of ozone to filter out harmful ultraviolet rays from the Sun in addition to meteor bombardment.
But it also could be a sign that intelligent life takes a long time to develop and is therefore likely to be rare. The universe, at about 13.8 billion years, is only three times older than Earth.
The researchers drew on astrophysics, geology, chemistry, biology and other fields to develop their model of the creation of life.
One of the authors of the paper, Professor Ralph Pudritz, of McMaster University in Canada, said the evidence seemed to be pointing in one direction.
“Because there are so many inputs from so many different fields, it’s kind of amazing that it all hangs together,” he said.
“Each step led very naturally to the next. To have them all lead to a clear picture in the end is saying there’s something right about this.”
“We’re thrilled that we can put together a theoretical paper that combines all these threads, makes clear predictions and offers clear ideas that we can take to the laboratory.”
He said it seemed clear that RNA would have evolved before DNA.
“DNA is too complex to have been the first aspect of life to emerge,” Professor Pudritz said. “It had to start with something else, and that is RNA.”
Ben Pearce, a graduate student at McMaster who co-wrote the paper, said this was the first time all the evidence had been put into a model.
“No one’s actually run the calculation before. This is a pretty big beginning. It’s pretty exciting,” he said.
It is thought the first molecules replicated themselves – the most basic definition of life – by folding over and drawing in similar material from the environment. 
This simple process began the process of evolution as molecules that were better suited to their environment became more numerous and those that were not ‘died’ out.
Understanding this process, Mr Pearce said, was “the Holy Grail of experimental origins-of-life chemistry”.

Nobel winners identified molecular ‘cogs’ in the biological clocks that control our circadian rhythms

Nobel winners identified molecular ‘cogs’ in the biological clocks that control our circadian rhythms


(The Conversation is an independent and nonprofit source of news, analysis and commentary from academic experts.)
Carrie L. Partch, University of California, Santa Cruz
(THE CONVERSATION) Circadian rhythms control when we’re at our peak performance physically and mentally each day, keeping our lives ticking in time with Earth’s day/night cycle. This year’s Nobel Prize in Physiology or Medicine was awarded to three American scientists, Jeffrey Hall and Michael Rosbash of Brandeis University and Michael Young of Rockefeller University, for shedding light on how time is measured each day in biological systems, including our own bodies.
From Darwin’s finches on the Galápagos Islands to modern city dwellers, organisms adapt to their environment. Regular 24-hour cycles of day and night on Earth led to the evolution of biological clocks that reside within our cells. These clocks help us unconsciously pick the best time to rest, search for food, or anticipate danger or predation.
The field of modern circadian biology got its start in the 1970s, when geneticist Seymour Benzer and his student Ron Konopka undertook a revolutionary study to track down the genes that encode biological timing in fruit flies. With that gene in their sights, the labs of Hall, Rosbash and Young ushered in the molecular era of circadian biology as they untangled the molecular mechanisms of biological timekeeping.
To get started, Benzer and Konopka performed a simple experiment: tracking when the fruit fly Drosophila melanogaster would emerge from its pupal case. This developmental process, called eclosion, served as a powerful tool to study the complicated biological process of circadian rhythms. Because Drosophila pupae only emerge at a specific time of the day, Konopka could measure the timing between rounds of eclosion for different strains of flies and identify those that had a bad clock. By isolating fly strains with timing problems, they hoped to be able to zero in on the relevant genes that controlled this internal clock.
In the end, Konopka found three mutant strains: one that had a short, 19-hour day, one with a long, 28-hour day, and one mutant that appeared to have no clock at all. Using genetic tools, he was able to show that each of the responsible mutations lay remarkably close on the same chromosome, suggesting that they were all located within a single gene, which Benzer and Konopka named period for its apparent control over clock timing.
Then the race was on and in 1984, two teams finally identified this so-called clock gene period in flies: the labs of Jeffrey Hall and Michael Rosbash working in close collaboration at Brandeis, and Michael Young’s lab at Rockefeller.
With the gene in hand, these groups then aimed to figure out how period fit into a biological clock. The first clue came when Jeffrey Hall and Michael Rosbash discovered that the protein encoded by this gene (called PER) increased during the night and decreased during the day, suggesting that levels of the protein might somehow communicate time information to the rest of the cell.
If you just imagine how a biological clock might best keep track of time over a day, you might jump to a mental picture of an hourglass timer. Sand gradually disappears over time; when all the sand is gone, it could signal the process to begin again. Was PER the substance that kept biological time by gradually changing throughout the day?
One key insight came when Hall and Rosbash reasoned that this PER protein might actually block the activity of the period gene, turning itself off each day. As levels of PER build up over the course of the night, less and less new PER protein would be made. Eventually the protein levels drop and the process starts over again. This is called a negative feedback loop. It’s the same type of biological balancing act that keeps everything from your blood sugar levels to your circadian rhythms in line throughout your body.
This kind of negative feedback system is similar to how a thermostat controls the temperature of a room. If the temperature drops below the set point, the thermostat turns on the heater. When the room gets too toasty, the thermostat turns off the furnace. Here, negative feedback – a build up of heat – works to control the heater and maintain a constant temperature.
Now imagine having to repeat this process over and over each day with nearly exact timing. Biological clocks use negative feedback from clock proteins like period to turn themselves on and off again each 24 hours. Additional studies in the Young lab identified other key genes – dubbed Timeless and Double-Time – that fit into this puzzle by controlling how PER travels around the cell to turn itself off each day.
Work over the last two decades has rounded out a much deeper understanding of circadian rhythms to show how most organisms have clocks based on feedback loops similar to Drosophila. Rosbash’s lab identified part of the PER protein known as the PAS domains that we now find in many clock proteins from fungi and plants to humans. PAS domains help clock proteins like PER pair up with their partners to control the negative feedback loop.
By comparing differences in the structures of PER PAS domains of Drosophila and mice, scientists are now beginning to learn how the protein “cogs” of the molecular clock fit together to tell time. Understanding circadian rhythms at atomic resolution like this allows us to explain how newly identified mutations in PER lead to changes in clock timing and open the door to therapeutics that could harness the power of circadian rhythms to improve human health.
We now have a much greater appreciation for the central role that circadian rhythms play in coordinating our lives with Earth’s day, controlling everything from your metabolism to the timing of sleep. Young’s lab recently identified a prevalent mutation in a human clock gene, cryptochrome 1, that lengthens the cellular clock and makes it difficult to get to bed before midnight. This inherited “night owl” gene is estimated to be pretty common, found in nearly 1 out of 75 of us.
Understanding the powerful regulation of biology by circadian rhythms is beginning to lead to far-reaching changes in policy. For example, rather than arbitrarily force our sleep schedules into routines that require early morning wake times, some researchers are showing that adjusting our schedules to fit our natural rhythms may pay off at work and school. This is particularly true for adolescents, who have a natural “night owl” tendancy – delaying school start times by even just one hour can significantly improve academic performance.
The science is now far enough along in our understanding of circadian clocks that researchers are working to optimize work and sleep schedules with our biology in mind. And all these policy innovations are built on the foundation of the Nobel-winning research with those tiny fruit flies.
