Do you have to work to keep Aubas spirits up with everything that has gone on this season?

No. You know Aubas character hes someone really lively, always joking, always smiling. He had a difficult season so many of us as a club and a staff try to support him as much as possible the way that the team did as well. When he had some personal issues they were right behind him. As I said before football gives you an opportunity. Hes in a good place right now and hes very hungry to do something.

Is he the same Auba as ever?

Well everything affects but you have to come through that. Its about how you react to the difficulties in your career which youre going to have at some stage. He had some this season and its about showing the direction and the capacity to overcome that.

What do you believe the Arsenal DNA to be? There have been some suggestions this week that has gone from the club.

Well, our DNA is related to many factors. First the history that we have, how we represent our values, our togetherness in what it is the team, what is the plan and what we are trying to transmit to the world with that. I believe that what we are trying to do is very much linked to that.

There is still things to do, yes, but there was always this. This game is evolving, this club is evolving. This club is not the same as 20 years ago. Its all the time something you have to embrace but at the same time evolve

Thierry Henry said those qualities are long gone. Is that true?

I said that there a fundamental things that we have to recover and its in our hands to do that. I think that is a responsibility for a lot of people. Not just the team, not just the board not just the owners but everybody that loves, really loves, this football club.

The club has been in Europe in every season since the 95/96 season. How important, in terms of both prestige and finance, is getting back into Europe for you next season?

Well, I think it gives you the platform, visually first, as you mentioned, and then because its related to our history and the demands that this club has got. Then because obviously financially the way to attract sponsors, to attract players, to improve your squad and to compete for the big trophies you have to be in Europe. Thats the challenge weve got ahead of us.

Throughout your time as a player and a manager how much does Arsenals ability to pull out important results give you confidence they could do the same again tomorrow night?

Well, weve got experience from the past. Weve got experience from this season in many ways. The last one in Villarreal when we were in a really difficult position, 2-0 down and with 10 men but we still managed to push something out. We have a big shot tomorrow.

Some players are likely to leave the club at the end of the season. Have those decisions been made already or are there some players with whom it depends on their performances in these final games of the season?

A lot of things can change for many different reasons. Something is a plan and then a plan for someone that you think is going to stay for a reason that happens and it changes. So, its very difficult to predict 100% that plan is going to be what you expect it to be what you said.

What will you do differently in tomorrows game compared to last week?

Well, the way we started the game thats for sure. We did some things that we didnt talk about. We conceded an early goal that I think was difficult to swallow. It took us a little while to react and I think we had a difficult period. How we handled both boxes. And the discipline. To play with 11 players in this competition is key and we didnt manage to do that. When we do all the things that we have to do the game will be completely different.

Here's what "Confirmed with DNA" means on WikiTree. When you're ready to do confirmations, see DNA Confirmation.

"Confirmed with DNA" is a relationship status level that indicates a parent-child relationship has been supported by DNA testing in addition to traditional genealogical research. Using it means this icon will appear by fathers and mothers on profiles and most tree views:

This indicator should only be used when the specific parent-child relationship has been carefully confirmed using a method described on the DNA Confirmation page and a source citation like the examples on the DNA Confirmation page is added to the child's profile.

If there isn't a proper source citation the "Confirmed with DNA" relationship status should be changed (by you or another member) to "Confident".

Confirmation is not absolute proof. Major caveats include:

"Confirmed with DNA" cannot be used if the genealogy is incomplete. If a DNA testing company estimates that you're a close match with someone else, you can be fairly confident that you and your match share a common ancestor in a genealogical time frame. However, you may not know the identity of the common ancestor, or you may not be confident about each link in the chain of parent-child relationships back to the common ancestor.

This is very common. It's likely to be the case with most of your matches.

"Confirmed with DNA" should only be selected after using one of the methods described on the DNA Confirmation page.

If a relationship is supported with DNA evidence but cannot be considered confirmed using one of the approved methods use the Confident status instead of Confirmed with DNA.

It's recommended that you still follow the basic source citation format described on the DNA Confirmation page when using a DNA test match as a source on a profile, even if the relationship is not confirmed. You may also wish to use a === DNA === subsection under the == Biography == with a full explanation.

The Relationship Status can be changed to Confirmed with DNA when more evidence is gathered through additional matches or if the current evidence is able to be more carefully analyzed.

Help:Confirmed with DNA - WikiTree

In a DNA molecule, the two strands are not parallel, but intertwined with eachother. Each strand looks like a helix. The two strands form a "doublehelix" structure, whichwas first discovered by James D. Watson and Francis Crick in 1953.In this structure, alsoknown as the B form, the helix makes a turn every 3.4 nm, and the distance between twoneighboring base pairs is 0.34 nm. Hence, there are about 10 pairs per turn.The intertwined strands make two grooves of different widths, referred to as the majorgroove and the minor groove, which may facilitate binding withspecific proteins.

Figure 3-B-3. The normal right-handed "doublehelix" structure of DNA, also known as the B form.

In a solution with higher salt concentrations or with alcohol added, the DNA structuremay change to an A form, which is still right-handed, but every 2.3 nm makesa turn and there are 11 base pairs per turn.

Another DNA structure is called the Zform, because its bases seem to zigzag. Z DNA is left-handed. One turn spans 4.6 nm, comprising 12base pairs. The DNA molecule with alternating G-C sequences in alcohol orhigh salt solution tends to have such structure.

Bacteria contain symmetry in their DNA signals that enable them to be read either forwards or backwards, according to new findings at the University of Birmingham which challenge existing knowledge about gene transcription.

In all living organisms, DNA code is divided into sections which provide information about a specific process. These must be read before the information can be used. Cells identify the start of each section using signposts, which scientists first identified in the 1960s.

It has always been assumed that these signposts enable genetic sequences to be read in a single direction. The new study, published in Nature Microbiology, however, shows that single-celled organisms have symmetrical DNA signposts. This means that the DNA code can be read in either direction.

Lead author, Professor David Grainger, explains: Most of the studies on gene signalling overlook the symmetry, but we think this is incredibly significant and represents a whole new level of regulating genes that has not yet been investigated.

The precise reasons for the two-directional reading are not yet clear and will require further investigation. One theory the team is considering is that it helps to avoid reading collisions with other sequences.

Although the current study focuses mainly on bacteria, the team speculate that the signpost symmetry is likely to be found in humans, animals and other organisms too. The next step for the research will be to investigate the phenomenon in yeast cells which more closely resemble human cells.

Professor Grainger adds: Understanding how genes are read is fundamental to many branches of biotechnology. Lots of medicines, for example, are dependent on being able to control how genes are read, so its important to fully understand how these signals work, and how we can use that knowledge to improve healthcare.

Sandy Hutton and Richie Millidge haven't seen each other since she gave him up for adoption in July 1967, but they've been talking and plan to meet again once COVID-19 restrictions are lifted.

Author of the article:

Richie Millidge had been searching for his birth mother for almost all of his 53 years. When he found her, he discovered she had been searching for him, too.

On July 26, 1967, Sandy Hutton, then Sandy Jones and only 17 years old, had a baby boy in Montreals Royal Victoria Hospital. With great reluctance, she gave him up for adoption.

I really didnt have much of a choice, she said. But first she held the newborn for the first and last time.

He had peach-fuzz hair and blue eyes. Of course we bonded. My sweet baby boy. Thats what I called him.

Hutton named the baby Leonard. That was changed to Richard when he was adopted four months later.

Years passed and Hutton married and had three more children: Lonney, Jen and Drew. She never kept their brothers existence a secret from them.

Hutton tried to find her son, but it was a closed adoption, and she didnt have key information she needed to locate him. There was even a failed attempt to find him by hiring a researcher to comb through birth records.

This advertisement has not loaded yet, but your article continues below.

Meanwhile, Millidge knew from the time he was seven or eight years of age that he had been adopted. He had never felt truly at home in his adoptive family, but his adoptive parents refused to provide any information about his birth mother. His adoptive father died when he was 11.

Last September, at the urging of his girlfriend, Tracy Ward, Millidge took a 23andMe mail-away DNA test, hoping to find family through through the companys relative finder database.

He didnt have any information to go on, not even a birth name. It was a shot in the dark, but it was worth a try, Ward said.

Millidges adoptive parents had told him his biological parents were Norwegian. He discovered, though, that he is mostly Irish and Welsh. There was a distant cousin in the database, who forwarded Millidges contact information to another distant cousin, who recalled the date of birth and reached out to Huttons stepmother.

Millidge and Hutton corresponded by email and checked out each others Facebook pages.

I recognized myself in him. He looked like me. He had my smile, Hutton said.

She seemed so down-to-earth. I knew it was her, Millidge said.

They wanted to wait until they had DNA confirmation before they actually spoke to each other, though. Millidge received the results confirming a match with Hutton on Feb. 21, and they agreed to speak by phone later that day.

I found his voice to be very soothing. He wasnt nervous. I wasnt, either. When he started talking, it was like a big weight had come off my shoulders. I had been worried that I wouldnt live long enough to meet him, Hutton said.

This advertisement has not loaded yet, but your article continues below.

We spent about three hours on the phone, Millidge said. I called her Mom. It just came naturally.

Soon after his three half-siblings, who live in Montreal, drove to Kanata to meet their newfound half-brother. He discovered he had four nephews. They discovered they had a niece.

They sat together for four hours. We hit it off like he was part of the family since Day One, said his half-sister, Jen Smith.

He looks more like my mother than any of us. I didnt even have to wait for the DNA match.

They have much in common. Like Millidge, Jen and Drew also work in the renovation business. The siblings share a taste for 70s rock. Theyre all fond of animals. Ward had noticed on social media that all of the siblings tended to make peace signs when they had photos taken.

It must be in the DNA, she said.

Millidge talks to his mother often, but the two wont meet face-to-face until COVID-19 restrictions have been lifted. He has always envied close-knit families and is happy to be part of one.

Its like theyve always been there, he said.

It has been wonderful to see my three children bring my son into the fold, Hutton said. Im at peace now.

Mother and child reunion: They had looked for each other for decades. A DNA test reconnected them. - Ottawa Citizen

Ledell Lee was convicted and sentenced to death for the 1993 murder of Debra Reese. Four years ago, in 2017, he was one of four inmates executed by the state of Arkansas before it had exhausted its supply of lethal injection chemicals. The 51-year-old maintained his innocence up to the day he was executed, according to THV11. The American Civil Liberties Union of Arkansas and the Innocence Project filed a lawsuit on behalf of Lees sister, Patricia Young, which resulted in the city of Jacksonville, AR ruling that new tests could be run on the evidence in his case.

Shortly after testing, both parties released summaries of the testing of evidence, which revealed genetic material from a male other than Lee was upon the murder weapon used to murder Debra Reese. The wooden club and bloody shirt that was wrapped around it did not match any in a national database. The groups also said that five fingerprints that had been discovered at the crime scene in 1993 were run but remain unidentified.

While the results obtained twenty-nine years after the evidence was collected proved to be incomplete and partial, it is notable that there are now new DNA profiles that were not available during the trial or post-conviction proceedings in Mr. Lees case, Nina Morrison, Senior Litigation Counsel at the Innocence Project, said in a statement.

Morrison said the groups hoped that the databases would generate additional information in the future. We are glad there is new evidence in the national DNA database and remain hopeful that there will be further information uncovered in the future, Young said in a statement.

During a news conference Tuesday, May 4, Arkansas Gov. Asa Hutchinson (R) defended Lees execution, saying that the new evidence is inconclusive and the jury found him guilty based upon the information that they had. Whenever you make tough decisions, whenever you have to carry out the decision of a jury, you realize that its been reviewed by the Supreme Court at every level. They affirm the convictions, and its my duty to carry out the law.

Lee died maintaining his innocence. The US Supreme Court facilitated the execution and others on Arkansas death row. In a decision that was split 5 to 4, the courts liberal justices said the state should not proceed. I have previously noted the arbitrariness with which executions are carried out in this country, wrote Justice Stephen G. Breyer. And I have pointed out how the arbitrary nature of the death penalty system, as presently administered, runs contrary to the very purpose of a rule of law.

Unfortunately, it looks like there might be a shadow of a doubt.

New DNA Test Casts Doubt on Guilty Verdict and Execution of Black Man in 2017 - Essence

According to a probable cause affidavit, detectives connected Clayton Foreman to the brutal murder using a family tree they constructed from a Genealogy website

BEAUMONT, Texas The man police say murdered a Beaumont teacher in 1995 knew her so well that she was in his wedding.

DNA evidence along with a genealogy database led police to arrest Clayton Bernard Foreman, 61, of Reynoldsburg, Ohio, on a capital murder charge.

Mary Catherine Edwards, who was found dead in her home, was a bridesmaid in the wedding of Foreman and his first wife, Jefferson County District Attorney Bob Wortham told 12News.

She was a bridesmaid in his wedding. So he knew her," Wortham said.

According to a probable cause affidavit obtained by 12News, DNA from semen collected from Edwards' home was matched back to Foreman 26 years later thanks to a genetics website.

The affidavit says that investigators identified second cousins of the suspect from the website and were able to work up a family tree. "Detectives obtained further DNA samples (30 DNA files were voluntarily submitted) from additional distant family members," the affidavit said.

Those DNA samples led investigators right to Foreman, the affidavit says. Trash was collected from the curb of Foreman's residence in Reynoldsburg, Ohio, and analyzed by the DPS crime lab in Houston.

"DNA collected from the trash run of Clayton Foreman's residence is a match to the DNA extracted from the semen collected from Edwards' body in 1995," the affidavit states.

CONNECTING THE DOTS

During their investigation into Foreman, detectives discovered he pled guilty to raping a classmate at Forest Park High School in 1981.

In that case, police said that Foreman gave the victim a ride home after finding her stranded at a gas station. Police say Foreman "bound her hands behind her back with a belt and held a knife to her throat" before sexually assaulting her.

Police say that 1981 rape had a number of similarities with Edwards' murder.

Edwards, 31, was last seen alive on January 13, 1995.

Her parents became concerned after phone calls went unanswered. When they went to her house to check on her, they found her drowned in an upstairs bathroom.

The probable cause affidavit says that Edwards was found in a bathtub with her hands handcuffed behind her.

Evidence at the time showed that she had been sexually assaulted before she was killed, according to a DPS news release.

"There are numerous similarities in the 1981 case and the Edwards' murder," the affidavit states. "First, Edwards and the first victim both went to high school with the suspect. Secondly, their hands were bound behind their back. Thirdly, both were sexually assaulted."

Police say that in the 1981 rape, Foreman claimed to be a police officer, and they say the suspect used police tools during Edwards' murder.

Foreman was arrested and charged with capital murder last week. He is awaiting extradition back to Jefferson County.

Former students say Edwards touched a number of lives in Southeast Texas and news of an arrest in connection with her death has brought former students a sense a peace that hasn't been felt in a while.

"Her allowing me to be who I was, which was kind of shy and withdrawn, it helped me to come out of that shell at that time." Demtria Green said.

Edwards was Green's teacher at Price Elementary in 1992.

"It was sad hearing that because she was a real nice lady, and when I did hear it on the news the state that they found her in, that was horrible," former student Malcom Wells said.

This is a developing story. We will update with more if and when we receive more confirmed information.

The value of dirty DNA

Environmental DNA can identify the presence of species, even from the distant past. Surveying three cave sites in western Europe and southern Siberia, Vernot et al. identified nuclear DNA and confirmed that it is from the close relatives of anatomically modern humansNeanderthal and Denisovan individuals. A phylogenetic analysis and modeling show that the DNA in sediment samples from several layers corresponds to previously studied skeletal remains. These results demonstrate that environmental data can be applied to study the population genetics of the extinct Neanderthal and Denisovan lineages, identifying a turnover of Neanderthal populations 100,000 years ago.

Science, this issue p. eabf1667

The study of hominin history has progressed through both archaeological and genetic insights. Although DNA sequencing from hominin skeletal remains allows the association of ancient populations with specific places in time and space, many archaeological sites lack associated hominin remains, limiting the scope of genetic analyses. Even when ancient hominin remains are found, they often do not cover the full time span of a site or sampling them for DNA may not be possible. The fossil record is particularly sparse for Pleistocene hominins, leaving large gaps in our understanding of the genetic histories of archaic and early modern humans.

Recent work has demonstrated the feasibility of sequencing ancient mammalian mitochondrial DNA (mtDNA), including that of hominins, from Pleistocene cave sediments. However, mtDNA represents only the maternal lineage and thus provides limited data for the resolution of population relationships. It is therefore desirable to complement mtDNA analysis with the retrieval of nuclear DNA, but no strategies are in place to enrich hominin nuclear DNA from a background of related sequences from other mammals present in most sedimentary deposits. To close this gap, we developed a set of probes for hybridization capture that targets 1.6 million ancestry-informative positions in the hominin nuclear genome, specifically at loci with high mammalian sequence divergence. We then developed computational methods to deplete residual microbial and faunal DNA sequences, along with methods to account for such non-hominin DNA in population genetic analyses.

We applied these methods to explore the history of Neanderthal populations in western Europe and southern Siberia using sediment samples from three Pleistocene caves: Galera de las Estatuas, a site in northern Spain with 40 thousand years of Neanderthal occupation but that is genetically unexplored, and Chagyrskaya and Denisova Caves, which have previously yielded high-coverage genomes of two Neanderthals and one Denisovan hominin. In total, we recovered Neanderthal or Denisovan mtDNA from >60 sediment samples and nuclear DNA from 30 of these. For Chagyrskaya and Denisova Caves, our phylogenetic results from sediment DNA were consistent with previously published results from skeletal remains, confirming the accuracy of our approach. At Galera de las Estatuas, we recovered Neanderthal DNA from layers spanning nearly the entire stratigraphy, and identified a population turnover ~100,000 years ago accompanied by a loss of mtDNA diversity. By incorporating genetic data from previously published skeletal samples, we associated this turnover with two putative radiations in Neanderthal history.

We developed methods for the effective retrieval and analysis of ancient hominin nuclear DNA from sediments and used them to uncover previously unknown events in Neanderthal history. This work demonstrates that detailed genetic analyses are now possible for many more archaeological sites than previously thought, with DNA from abundant sediments allowing dense time-series studies that are independent of the fossil record.

Bones and teeth are important sources of Pleistocene hominin DNA, but are rarely recovered at archaeological sites. Mitochondrial DNA (mtDNA) has been retrieved from cave sediments but provides limited value for studying population relationships. We therefore developed methods for the enrichment and analysis of nuclear DNA from sediments and applied them to cave deposits in western Europe and southern Siberia dated to between 200,000 and 50,000 years ago. We detected a population replacement in northern Spain about 100,000 years ago, which was accompanied by a turnover of mtDNA. We also identified two radiation events in Neanderthal history during the early part of the Late Pleistocene. Our work lays the ground for studying the population history of ancient hominins from trace amounts of nuclear DNA in sediments.
