A chemical reaction that gives food flavour could have helped evolution, one study suggests. According to New Scientist, the Maillard reaction is when the temperature between sugars and amino acids rises above approximately 140°C. It often occurs in food such as toasted bread, meats and roasted vegetables. Caroline Peacock at the University of Leeds wanted to explore whether it could happen at lower temperatures. To do this, scientists added iron or manganese minerals to a solution made up of sugar glucose and the amino acid glycine. When the substance was incubated at 10°C, the process was sped up by around 100 times. The temperature is said to be similar to the seabed at the edges of continents. Peacock and the team discovered that the Maillard reaction also occurs on the ocean floor, where iron and manganese minerals are often found. If this is the case, it could cause the carbon in sugars and amino acids to be stored in "large, complex polymers that microbes find harder to ingest," Peacock said, as per the publication.

The team estimated that the minerals could lock away roughly 4 million tonnes of carbon every year. If this process didn't exist, the atmosphere could have warmed by a further 5°C over the past 400 million years, the study suggested. "This process has such a profound impact on atmospheric oxygen," she says. "Because complex life forms require higher levels of oxygen, as they’re more energetically demanding, we think it’s reasonable to surmise this process had a hand in creating conditions required for complex life."

It’s time for spiritual restoration and creative expansion. As we round out Cancer season, we’re welcoming a much-needed change of pace. Mars, the planet of action, began a six-week transit in Virgo last week, and Mercury is continuing its two-week transit through the sign of Leo. This Earth-Fire combo sparks a blend of intellect and action in our minds and in our lives. The highlight of this week is the Cancer new moon occurring at 2:32 p.m. EST on July 17. This occurs on the same day that the lunar nodes switch out of the Taurus-Scorpio axis and enter the Libra-Aries axis. The next year and a half will feel karmically lighter and more expansive as a result of this shift, and all zodiac signs would benefit from focusing on living in the moment rather than trying to project themselves into the future. Venus begins its six-week retrograde in Leo on July 22 at 9:33 p.m. EST, signaling a time for introspection and reexamination of one’s core values. Less than twenty minutes later, the Sun enters Leo for the next four weeks. This Leo season will have a cosmic twist to it due to the energy of Venus retrograde asking us to be boldly honest with ourselves and learn from our past. What need for social approval can you do your best to release at this time? This week encourages us to direct our attention to intimately approving of our own selves, right here, right now, without seeking external validation. Validate yourself instead.

It was billed as the glistening jewel in Formula 1’s crown. In all but name, this was the new Monaco. But the biggest race on the sport’s 2023 calendar – the inaugural Las Vegas Grand Prix on the streets of Sin City – descended into a total disaster on opening night. Even for the entertainment capital of the world, nobody could have conjured up this story of incompetence. Make no mistake: this was a shambles. A complete and utter shambles. What started with Carlos Sainz’s car substantially damaged by a loose water valve cover just after 8:30pm on Thursday night ended at 4am on Friday morning in front of empty grandstands, with fans instructed at 1:30am to head for the exits. Put out of their misery, they trudged home having seen just eight minutes of cars on track. For two men with their heads exhaustingly bowed downwards on a fan zone table, it was finally home time. A refund must surely be imminent. F1, so we were told, had left no stone unturned in preparation for this racing extravaganza. A new $500m pit building was built. Unlike their previous forgettable experience in Vegas back in the 1980s, they had cajoled all the major casinos and hotels into a favourable position. The third of three races in the United States this year, the Netflix-inspired American audience waited eagerly for action to commence. But for all the relentless marketing, self-promotion and hype, the fundamental basics of the sport were ruefully ignored here. A day on from an opening ceremony which made three-time world champion Max Verstappen feel like a “clown”, confusion immediately reigned when Sainz pulled his Ferrari car over on the Vegas strip, eight minutes into the first of two practice sessions scheduled. Yet replays quickly showed that the Spaniard had not made a mistake. He had instead run over a loose manhole cover, triggering a complete failure of the engine. The floor of the car was also badly damaged and, frankly, he was lucky the car did not spear off into the wall. With safety coming first – and every drain cover now needing to be double-checked on the strip section of the circuit – the session was cancelled. To add salt to the wounds, Sainz was later given a time penalty due to taking a new gearbox as a result of the incident. Sometimes, common sense fails to prevail. Usually so softly spoken, Ferrari boss Fred Vasseur was livid with F1 and labelled the farcical start to proceedings as “unacceptable” in an exquisitely timed team principals’ press conference. Sat next to him was Mercedes chief Toto Wolff, who took the opposite view and hit the roof when asked if the evening’s events represented a “black eye” for F1. “It’s completely ridiculous,” he said. “How can you even dare talk bad about an event that sets the new standards to everything?” Really, Toto? New standards? With a second one-hour practice session scheduled for midnight, the updates coming through were inadequately sparse. Every hour was amateur hour. Spectators who had paid thousands of dollars to experience night one in Vegas were left in the dark. Would we have any cars on track? The answer was yes – but there would be no fans to see it. Following delay after delay, a start time of 2:30am was eventually pencilled in. But an hour earlier, fans were told over the tannoy to leave owing to “logistical considerations.” In reality, staff had to depart in order to return for their scheduled start time later on Friday – meaning the fans were given their marching orders too. So the obvious question begs: why on earth was that decision not made sooner? By the time cars entered the track, manholes suitably covered, there was an eerie emptiness on the terraces. For an event anticipated to attract 100,000 people a day, it felt like the pandemic once again. It did not matter that Charles Leclerc was fastest; what mattered was that by the time the day finally concluded, nobody really cared. All in all, it represents a mighty old screw-up from Formula 1. Verstappen said on Wednesday the whole event felt like “99% show, 1% sporting event” and on this evidence it is hard not to agree with him. The start times were late enough before it alienated an entire American audience eager for some sleep. There are some serious lessons to be learned. And looking ahead to two more days, as team personnel and reporters alike trundle home with glimpses of the sun on the horizon, it may well take something special to reinvigorate proceedings this weekend. It is recoverable – it has to be, given the investment made here. But let there be no doubt: with the eyes of the world on F1 and the bright lights of Vegas, they dropped the ball tonight. This morning. Whatever the time is.

Abortion opponents are trying again to implement restrictions in the latest round of court and legislative action on the divisive issue. This round of efforts centers on states that have considered bans before and a policy that's been bouncing around federal courts. Here are key things to know about the latest developments in the saga of how abortion policy will settle after the U.S. Supreme Court last year overturned Roe v. Wade and the nationwide right to abortion. PURPLE STATE POLICY Since the Dobbs ruling last year, tighter abortion restrictions have been enacted in most Republican-controlled states and protections of abortion access have gone into effect in most that are dominated by Democrats. But there hasn't been such a uniform story in the 11 states with divided government control. Virginia has kept its status quo, for instance, while Vermont has adopted a constitutional amendment to preserve abortion access and Louisiana and Kentucky have bans in place. Change came quickly in North Carolina in April when one state lawmaker flipped from Democrat to Republican, giving the GOP enough votes to override gubernatorial vetoes. Lawmakers promptly passed a ban that's less restrictive than most — allowing abortion for the first 12 weeks of pregnancy, which would be among the least restrictive of the new bans. Democratic Gov. Roy Cooper vetoed it. But lawmakers on Tuesday overrode that veto and the new law is set to take effect July 1. TRYING AGAIN ON BANS IN NEBRASKA, SOUTH CAROLINA Nebraska and South Carolina are both Republican-dominated states where GOP lawmakers have struggled to agree on the details of abortion bans. Both are considering bans this week, just weeks after earlier efforts narrowly fell short on procedural votes. And both have resurrected legislation that's less restrictive than versions that were rejected previously. In South Carolina, Republican lawmakers were divided on whether to ban abortion at all stages of pregnancy or only after cardiac activity can be detected — generally around six weeks, often before women know they're pregnant. A version of a less stringent ban is now under consideration. In Nebraska, lawmakers balked at a ban after six weeks. The unique unicameral legislature is now considering a ban on abortion at 12 weeks' gestation. It's been added to a bill that would also ban gender-affirming care for minors. RESTRICTION IN MONTANA In Montana, Gov. Greg Gianforte signed a ban Tuesday on dilation and evacuation abortions, which are normally performed in the second trimester of pregnancy. A legal challenge is expected. And it wouldn't be the first challenge on the policy in the state. A judge ruled last month that she would not block the ban preemptively, before it was signed into law. The state in 2021 adopted a broader ban on abortions after 20 weeks of pregnancy, but the state Supreme Court ruled that it will not enforce it pending a court challenge, leaving abortions by some means legal until viability, around the 24th week. COURT ARGUMENTS ON AN ABORTION PILL Most of the legal battles on abortion since the Supreme Court’s Dobbs decision in 2022 have centered on whether individual state constitutions protect the right to abortion. But one has implications nationally. An anti-abortion group sued seeking to rescind the U.S. Food and Drug Administration’s 2000 approval of mifepristone, one of two drugs used in combination in most medication-induced abortions in the U.S. A federal judge in Texas agreed. The New Orleans-based 5th U.S. Circuit Court of Appeals is hearing arguments Wednesday on the matter. In the meantime, the U.S. Supreme Court has said that mifepristone can remain on the market. It is already barred from being used in abortions, with some exceptions, in states with bans in place. An immediate response from the circuit court is unlikely. The case is expected to return to the nation’s top court eventually. The Texas-based case could be merged with one in Washington, where another federal judge ruled last month that mifepristone restrictions cannot be rolled back in a group of Democrat-led states that filed lawsuits.
