NASA’s Perseverance Mars rover snapped this view of a hill in Mars’ Jezero Crater known as “Santa Cruz” on April 29, 2021, the 68th Martian day, or sol, of the mission.
Each time it rains, fish dwelling downstream of storm drains are uncovered to pollution, together with the tire-derived compound 6PPD-quinone, within the runoff. Lately, this substance has been linked to large die-offs of coho salmon throughout the U.S. West Coast. Now, researchers in ACS’ Environmental Science & Expertise Letters report that publicity to 6PPD-quinone at environmentally related ranges will also be lethal for rainbow and brook trout, although not for Arctic char or white sturgeon.
Rubber tires are fortified with protectants, equivalent to N-(1,3-dimethylbutyl)-N’-phenyl-p-phenylenediamine or just 6PPD, to allow them to be safely pushed for a very long time. Nevertheless, because the treads put on down and items flake off over time, small rubber particles scatter throughout roads. There, they react with oxidants equivalent to ozone within the air, changing 6PPD to 6PPD-quinone, which washes into waterways together with the supply tire particles in stormwater runoff. Earlier research reported that publicity to small quantities of 6PPD-quinone is poisonous to coho salmon — a preferred fish amongst leisure fishers and an environmentally essential species — and certain induced the phenomenon in city streams referred to as city runoff mortality syndrome. Conversely, one other research indicated that zebrafish and Japanese medaka can face up to even very excessive quantities of 6PPD-quinone. So, Markus Brinkmann, Markus Hecker, Steve Wiseman and colleagues wished to see whether or not this contaminant poses a danger to a broader vary of commercially, culturally and ecologically essential fish species.
The researchers uncovered juvenile brook trout, rainbow trout, Arctic char and white sturgeon to various ranges of 6PPD-quinone. They discovered that even small concentrations, equivalent to these often occurring in floor waters after stormwater runoff occasions, have been deadly to brook and rainbow trout. For each trout species, the researchers noticed an elevated blood glucose degree after 6PPD-quinone publicity, suggesting it affected the fish’s vitality metabolism pathways. Nevertheless, not one of the Arctic char and white sturgeon died after 4 days of publicity to a excessive degree of the contaminant that was just like the utmost quantity beforehand noticed in stormwater runoff. The outcomes point out mortality from publicity to 6PPD-quinone varies amongst fish species, however for animals that do not die, doable non-lethal results could possibly be occurring and want additional examination, the staff says.

When Serb forces bombed my dwelling in Sarajevo, I used to be hiding in a neighbour’s home simply throughout the road. It was July 19, 1995, and I used to be 4 years outdated and placing on my purple socks – the socks my father had exchanged a packet of cigarettes for, the one socks I had throughout that final yr of the struggle.
My mom had promised to take me to play within the entrance yard of our neighbour’s home – a small patch of grass, concrete and freedom in a metropolis that was below fixed Serb shelling.
However first, my mom returned to our household dwelling to take a fast bathe. That was when the air raid siren that had turn into such a characteristic of our each day lives sounded.
Then got here the blast.
The subsequent jiffy felt like an eternity. My uncle tried to cease me from operating in direction of the home. I screamed and screamed for my mom, till she ultimately emerged from the smoke.
As a substitute of taking part in that day, we cleaned the rubble from our dwelling and I collected my doll’s physique elements, fastidiously placing her again collectively once more.
When Russia attacked Ukraine on February 24, I stored refreshing my Twitter feed and studying the information, attempting to grasp what was going down on the bottom. On the night time of February 27, when the primary footage emerged of a residential constructing in Kyiv being hit by a missile, I couldn’t sleep. The reminiscences of my circle of relatives dwelling being hit all these years earlier than flooded again to me.
“When a baby goes by means of a struggle trauma, they expertise issues in a unique method [than the adults],” explains Selma Bacevac, a psychotherapist specializing in the Balkans who relies in Florida in the USA.
“The kid doesn’t have the capability to grasp that someplace on the market, there may be security. [The] baby doesn’t bear in mind the time when issues had been peaceable, nor does [the child] perceive the idea of time and the way it works.”
Now, as Europe braces for the likelihood that the struggle in Ukraine may spill over into different nations, this concern feels significantly actual for those who have had earlier wars with Russia or had been at one time invaded by the Soviet Union.
“This collective trauma that Europe or every other society carries, makes individuals really feel like they’re on this collectively, however it additionally makes them really feel extra fearful of latest assaults,” says Bacevac.
Bosnia and Herzegovina, which marked 30 years of independence from the previous Yugoslavia on March 1, feels significantly susceptible to the potential of a brand new struggle. Bosnia’s independence, shadowed by the brutal four-year struggle that claimed greater than 100,000 civilian lives, and gave beginning to Republika Srpska, is as soon as once more hanging by a thread as Republika Srpska’s Serb chief, Milorad Dodik, has threatened to secede from the nation.
“I barely slept through the night time that led to [Russia’s] invasion of Ukraine,” says Faruk Sehic, a 52-year-old poet and Bosnian struggle veteran.
“I stayed awake till 2am, worrying and anticipating the worst. I knew that the struggle would erupt [in Ukraine], and I didn’t need that to occur.”
Like me, Sehic had been following the newest Russia-Ukraine updates within the information and thru social media. For Sehic, lots of the occasions surrounding the struggle in Ukraine had been far too comparable to people who had performed out within the days resulting in Bosnia’s 1992-1995 struggle: the open threats, the refugees fleeing, the heavy shelling.
Sehic’s good friend and fellow poet from Ukraine, Andriy Lyubka, discovered himself within the midst of this newest struggle. On the second day of Russia’s invasion, he despatched Sehic a textual content message: “They’re bombing Kyiv.”
The message left Sehic in a state of deep misery.
“I advised him it’s crucial that you simply write the whole lot down,” Sehic remembers.
In the course of the struggle in Bosnia, Sehic needed to flee his hometown of Bosanska Krupa, which was managed by Serb forces. He lived in a number of Bosnian cities through the struggle, together with besieged Sarajevo. The struggle helped him to grasp the significance of writing down the historical past of a rustic that would disappear earlier than his eyes. That’s the reason he has suggested Lyubka to write down – in order that he can use these notes in his future work.
Information of the assaults on Kyiv deliver a specific trauma for individuals like Sehic, who nonetheless bear in mind dwelling below what was later described because the longest siege within the historical past of contemporary warfare. Throughout this time, Sarajevo additionally skilled fixed sniper assaults from occupying Serb forces, killing near 11,000 individuals, together with 1,600 kids.
“These of us [in Europe] who’ve skilled struggle trauma, are watching these [events] on TV from a unique standpoint,” says Bacevac.
“I’ve acquired numerous messages from individuals within the Balkans saying, ‘this seems like me, this seems like my aunt, my father’. [People] are being retriggered, retraumatised.”
Bacevac says this will manifest in some ways, together with as panic assaults, survivor’s guilt, flashbacks, an incapability to sleep, emotional outbursts, nightmares and a sense of worthlessness or helplessness. Some individuals might discover themselves shopping for meals to retailer and making different preparations for worst-case eventualities.
For Amina Agovic, a 41-year-old authorized professional, this fear is doubled.
Agovic escaped the struggle in Bosnia as a 10-year-old, along with her mom and youthful sister. She spent most of her early childhood dwelling in exile in Australia, however in the present day lives in Finland along with her husband and their 4 kids. Though Finland has a 1,340km-long border with Russia and was invaded by the Soviet Union through the temporary 1939-1940 Winter Conflict, the nation’s President Sauli Niinistö has sought to guarantee residents that the struggle in Ukraine is not going to spill over into their nation.
However Agovic and her household had been hoping to completely relocate to Bosnia this yr. Now, she is not certain that it will likely be protected to take action.
She says that, regardless of Finland’s historical past with Russia, she feels it’s safer to stay the place she is.
In latest months, Dodik, who’s an ally of Russian President Vladimir Putin, has been extra vocal about wanting Republika Srpska to turn into an impartial state, probably becoming a member of Serbia. For Bosniaks, who had been ethnically cleansed from these areas, this secession is unacceptable.
However these threats by nationalist Serbs have been supported by Russia, and Russian government-backed foundations have been accused of selling genocide denial over the Srebrenica bloodbath, during which greater than 8,000 Bosniak males and boys had been killed by Bosnian Serb forces in July 1995.
In March 2021, the Russian Embassy in Bosnia and Herzegovina warned Bosnia that if it joined NATO – one thing it additionally staunchly opposes for Ukraine – “our nation should react to this hostile act”.
A day after Russia’s assaults on Ukraine, Germany’s Die Welt newspaper revealed an article suggesting that former Yugoslavia nations, Bosnia specifically, are subsequent on Russia’s agenda. It’s but unclear whether or not this may imply a direct invasion.
“I’ll simply monitor the state of affairs and see how issues evolve,” Agovic says.
However with Russia additionally threatening Finland and Sweden with “severe military-political penalties” ought to they resolve to affix NATO, different European nations, together with Poland, have began to broaden their militaries.
For survivors of previous wars in Europe, these developments are troubling.
“[My mother] insists on us having passports prepared, and she or he plans for a risk of a struggle, although she lives with me in Florida,” says Bacevac. “Individuals who have survived struggle as adults have the necessity to really feel bodily protected, to really feel ready in case of the worst.”
DALLAS — U.S. Rep. Van Taylor of Texas mentioned Wednesday that he was ending his reelection marketing campaign and admitted having an affair following experiences that he had been in a relationship with the widow of an American-born recruiter for the Islamic State group.
The North Texas congressman’s announcement got here the day after former Collin County Decide Keith Self compelled Taylor right into a runoff for the Republican nomination.
A number of days earlier than Tuesday’s major election, some right-wing web sites reported on an interview with Tania Joya, who mentioned she had an affair with Taylor that lasted from October 2020 to June 2021. Joya, of the Dallas suburb of Plano, instructed The Dallas Morning Information on Monday night time that she had met the congressman by way of her work as an ex-jihadist serving to to reprogram extremists.
Taylor apologized for the affair in a press release shared with supporters Wednesday. It did not point out Joya by identify or reference her late husband, the Islamic State group recruiter.
“A couple of 12 months in the past, I made a horrible mistake that has induced deep harm and ache amongst these I like most on this world,” he wrote. “I had an affair, it was mistaken, and it was the best failure of my life.”
The Dallas Morning Information reported Wednesday that Joya contacted Suzanne Harp, one other candidate opposing Taylor within the major, hoping Harp would confront Taylor privately and persuade him to drop out and resign from Congress.
“All I needed was for Suzanne Harp to simply say, ‘Hey, I do know your little scandal with Tania Joya. Would you prefer to resign earlier than we embarrass you?’ However it did not occur like that,” Joya instructed the newspaper.
As an alternative, the newspaper reported, Harp despatched a supporter to interview the lady, then shared the interview with a pair of right-wing web sites.
In a press release, Harp mentioned the revelations have been “deeply regarding, and I am praying for all concerned.”
“Politics ought to construct up our households, our communities, and our political events. This story breaks my coronary heart, each as a spouse and as an American. Politics ought to by no means tear these sacred establishments aside,” she mentioned.
Taylor, a former Marine and Iraq warfare fight veteran, was thought-about one of many Texas delegation’s most conservative members when he was elected in 2018. However he has been sharply criticized by the occasion’s proper wing for voting to certify the 2020 election outcomes and supporting a fee to analyze the Jan. 6 riot on the Capitol.
Joya’s first husband, John Georgelas, grew up in Plano, transformed to Islam and have become a high recruiter for the extremist Islamic State group. In 2013, he took her and their three youngsters to northern Syria the place, as Yahya Abu Hassan, he grew to become a very powerful American preventing for ISIS. He was killed in 2017.
Three weeks after their arrival in Syria, a pregnant Joya fled to Turkey with the kids, then to Plano to stay close to her in-laws. The couple was lined for years by tabloids in her native Britain and profiled in U.S. publications.
Towards the tip of the affair with Taylor, Joya mentioned she requested for assist to repay a bank card debt and another payments. He gave her $5,000, she mentioned.
“I wanted assist. I used to be like, simply assist me out as a result of that is the least — the very least — he might do,” she instructed the newspaper. “For him, it was like, ‘OK, on the situation you do not inform anybody.’ … I did not need to inform anyone something.”
Taylor tallied 48.7% of the vote on Tuesday, falling 823 votes in need of what he wanted to keep away from a runoff with 63,981 ballots solid. Self scored 26.5% of the vote, whereas Harp tallied 20.8%.
Self is an Military veteran and graduate of the U.S. Navy Academy. He has claimed Taylor drifted from his conservative roots within the GOP-dominant district. He was amongst those that closely criticized Taylor’s votes on the election outcome and riot investigation and Taylor’s vote to take away Accomplice statues from the Capitol.

“All it’s important to do is eat much less and transfer extra.”
Not solely is that this categorically unsuitable however this can be very irritating to listen to—particularly out of your physician. Sadly, your physician is sharing very outdated ideas with you. It takes an estimated 17 years for discoveries from scientific analysis to achieve your physician and shift his or her medical recommendation. The speak present hosts and web searches are additionally typically instructing incorrect or outdated info.
The issue is that even trusted sources equivalent to medical journals are sometimes propagating unhealthy info. The New England Journal of Drugs reported that “false and scientifically unsupported beliefs about weight problems are pervasive” in our medical journals.
Ideally, you’d discover the solutions for your self by finding out the five hundred,000 scientific papers printed on the topic and a few 100 new ones printed on daily basis. This, nonetheless, is a frightening activity and never one which lots of you’ll undertake. Dr. Whit Roberts of Well being Utah affords an alternate. “You may flip to consultants who’ve made it their life research to cull via the a whole lot of 1000’s of pages of analysis or extra prone to the medical doctors who comply with these consultants.” Roberts, a kind of medical doctors, tells us that there are some fascinating info that you’ve got doubtless by no means heard that may jump-start or maintain your weight reduction efforts on observe. Listed below are simply three of them.
By this time, you’ve got most likely heard of intermittent fasting. What you have not heard of is chronobiology or the research of how the rhythms of the solar, moon and seasons have an effect on our our bodies’ psychological, bodily and emotional cycles. That research gained the researchers the Nobel Prize in drugs in 2017. Roberts explains that their analysis has led to our refined understanding of the simplest type of intermittent fasting. Roberts says that it issues while you quick not simply how lengthy you quick.
Apparently, the outdated adage that breakfast is a very powerful meal of the day is definitely true, even supposing thousands and thousands of Individuals are skipping it. Among the many many belongings you’ll be taught as a weight reduction affected person at Well being Utah, is why consuming breakfast is essential. Roberts explains that energy eaten within the morning are handled otherwise by the physique than energy eaten at night time.
Within the morning, your physique is getting ready for the necessity of prepared vitality by changing your meals to glycogen, a short-term vitality storage molecule. To perform this, your physique burns these hated fats shops. It is an altogether completely different story within the night, nonetheless. The physique is getting ready for a restful, restorative night time’s sleep. Energy eaten at dinner or within the night are extra typically saved as fats, a long-term vitality storage molecule. “The take-home message,” Roberts says, “skipping dinner is much simpler than skipping breakfast for losing a few pounds. All different issues being equal you’ll lose extra weight fasting within the night than within the morning.”
A second weight reduction fact straight from scientific literature is that unhealthy micro organism in your intestine causes weight acquire. One among Robert’s sufferers discovered this the exhausting manner. Tory, a 43-year-old lady, went to Well being Utah after she all of a sudden began gaining weight. She gained 40 kilos inside six months regardless of being on a eating regimen. She went to the physician and had her hormones and thyroid examined. They have been positive. She even employed a private coach. Nothing she did appeared to make a distinction. She simply stored gaining weight.
At Well being Utah, Roberts performed a radical examination together with analysis of her medical historical past and testing. He discovered that she had had two programs of antibiotics for a extreme sinus an infection previous to the load acquire. These antibiotics had worn out portion of her good and unhealthy micro organism. Because the colonies of micro organism grew again, the unhealthy gained extra floor as she consumed soda and sugary treats that they preferentially fed upon.
Tory underwent a course of care at Well being Utah, misplaced 45 kilos, skilled a big improve in vitality, and noticed a dramatic lower in her lifelong nervousness. Now, Tory is a big advocate of Well being Utah and the therapies and therapeutic modalities supplied there.
The third science-supported weight reduction truth shared by Roberts shocks nearly everybody who hears it. Hen is extra fattening than beef. Yep, you and I’ve been duped. It has been proven that consuming only one rooster breast each 10 days may cause vital weight acquire, as proven in a couple of research. No marvel so many are combating weight reduction as they pressure down their diet-approved rooster breast on daily basis.
Well being Utah helps you chop via such misinformation, industry-biased propaganda, and fashionable myths. This text touches on just some of those. Roberts has developed his proprietary weight reduction protocols over his 25 years of follow incorporating evidence-based weight reduction strategies. If you happen to wrestle with cussed weight, it simply could also be that his scientific method to figuring out and correcting underlying causes of your cussed weight is best for you.
Roberts is fast to clarify that such cussed weight will be brought on by a a lot bigger number of circumstances past the scope of this text. These can embody toxins, insomnia, an infection, allergy symptoms, hormone imbalances, candida, emotional points, liver and gallbladder dysfunction, and lots of extra. He and his workers establish and handle all of those potential underlying circumstances with their weight reduction protocols. “Testing is the important thing to discovering if there are potential underlying points making your weight reduction efforts so tough,” says Roberts.
Well being Utah consultations embody same-day testing. Name 801-810-CARE (2273) or go to Well being Utah in the present day to schedule your weight-loss session and introduction to a novel weight-loss modality with Dr. Roberts.
In case your vital different would additionally like a session, point out this text and you may schedule the second appointment for no further value. That represents a financial savings of $59.

Abrupt shifts within the evolution of animals — quick intervals of time when an organism quickly modifications measurement or kind — have lengthy been a problem for theorists together with Darwin. Now a newly revealed analysis paper helps the concept even these abrupt modifications are underpinned by a gradual directional means of successive incremental modifications, as Darwin’s idea of evolution assumes.
Printed in Nature Communications immediately (Wednesday 2 March), evolutionary biologists from the College of Studying suggest a brand new statistical mannequin which seeks to clarify these sudden modifications and lengthy intervals of stasis which have been seen within the evolutionary historical past of some species.
The group led by Professor Mark Pagel together with colleagues Dr Ciara O’Donovan and Dr Andrew Meade, developed a statistical mannequin that reconstructed the body-size modifications which occurred all through the 170-million-year historical past of greater than 2800 mammal species.
The authors discovered that regardless of there being intervals for some mammals throughout which abrupt modifications in measurement happen, these occurrences may be understood as ‘regular’ modifications that draw on the pure variability that evolution routinely provides to pure populations.
Prof Mark Pagel, Professor of Evolutionary Biology on the College of Studying and lead writer of the paper mentioned:
“Our statistical mannequin offers a foundation for accommodating what has beforehand been a thorn within the facet of theorists equivalent to Darwin.
“Darwin’s idea of evolution by pure choice predicts gradual and incremental modifications to organisms occurring over very lengthy timespans. However the fossil file often reveals very abrupt modifications within the sizes, shapes, colors and different options of organisms, and these have been used for not less than fifty years to problem the Darwinian orthodoxy.
“We present on this paper that even these abrupt modifications are simply defined as circumstances of what’s often known as ‘directional choice’ — when pure choice strongly pulls a trait in a single course. No particular extra-Darwinian mechanisms are required.”
Many of those abrupt modifications occurred round 60-70 million years in the past, a interval that noticed the rise of many various mammal teams from earlier kinds. For instance, over a 100,000 yr interval an early small grazing animal (Conacodon entoconus), ancestral to immediately’s fashionable cows, antelopes, and giraffes, elevated in measurement over 70-fold. Extra just lately, the baleen whales (e.g., humpback, blue and sperm whales) have elevated over 100-fold in measurement from a small dolphin-like ancestor in the identical period of time (~ 7 million years) that separates fashionable people from their widespread ancestor with the chimpanzees.
