Study suggests antimicrobial used to promote livestock growth breeds bacteria more resistant to our natural defences
The blanket use of antibiotics in farming has led to the emergence of bacteria that are more resistant to the human immune system, scientists have warned.
The research suggests that the antimicrobial colistin, which was used for decades as a growth promoter on pig and chicken farms in China, resulted in the emergence of Ecoli strains that are more likely to evade our immune system’s first line of defence.
Its enzymes degrade polyethylene within hours at room temperature and could ‘revolutionise’ recycling
Enzymes that rapidly break down plastic bags have been discovered in the saliva of wax worms, which are moth larvae that infest beehives.
The enzymes are the first reported to break down polyethylene within hours at room temperature and could lead to cost-effective ways of recycling the plastic.
Nicolae Ceaușescu’s Romanian communist regime hailed his wife as an eminent chemistry researcher, though she had no genuine qualifications. But her name lives on in academic journals, and British institutions have yet to retract honours bestowed on her
Romanian researchers have called on academic publishers to remove Elena Ceaușescu’s name from almost two dozen scientific papers and books fraudulently published as her work, more than 30 years after the wife of the former communist dictator Nicolae Ceaușescu was executed.
Elena Ceaușescu was celebrated by state propaganda under her husband’s regime as a world-famous chemistry researcher, despite having no credible qualifications. The researchers say some of her work is still being cited and accessed, even though she was barely literate in science and unable to recognise basic formulas taught to first-year chemistry students.
Production of chemical could help make recycling more attractive and tackle global plastic pollution
Plastic bottles have been converted into vanilla flavouring using genetically engineered bacteria, the first time a valuable chemical has been brewed from waste plastic.
Upcycling plastic bottles into more lucrative materials could make the recycling process far more attractive and effective. Currently plastics lose about 95% of their value as a material after a single use. Encouraging better collection and use of such waste is key to tackling the global plastic pollution problem.
The Nobel laureate poet Sir Derek Walcott once said that the English language is nobody’s special property: “It is the property of the imagination.” Much the same could be said for science. It should be said. Except this isn’t quite so. Not yet.
Data on who is doing science has recently been released by the Royal Society, the UK’s premier scientific academy, using figures from the Higher Education Statistics Agency, whose data is by far the most systematic. The numbers show that in 2018-19, 19.2% of science, technology, engineering and maths academic staff aged 34 and under are Asian and 1.8% are black. In physics and chemistry, the proportion of black researchers stands at a sobering zero, rounded down, as these calculations do for ease of presentation, from literally one or two individuals. What’s interesting is that these small figures decrease further as a scientist’s age increases – as they travel through the hallowed halls of academia to become senior scientists. So while the UK has 10,560 science professors who are white, only 960 are Asian, 310 mixed and “other” and 65 black. This says that minorities who enter science are less likely to get promoted. Fewer of them go on to become those experts who evaluate which next-generation scientists should then get the training, the money and the jobs. “Unless this changes,” the Royal Society says, “there will be unbalanced representation of academic staff between ethnic groups working in higher education in comparison to the ethnic breakdown of the general population.”
The Hungarian-born biochemist who helped pioneer the research behind the mRNA technology used in the two Covid-19 vaccines showing positive results believes it was always a no-brainer.
“I never doubted it would work,” Katalin Karikó told the Guardian. “I had seen the data from animal studies, and I was expecting it. I always wished that I would live long enough to see something that I’ve worked on be approved.”
Cellular (T-cell) immunity against the virus that causes Covid-19 is likely to be present within most adults six months after primary infection, with levels considerably higher in patients with symptoms, a study suggests.
The data offers another piece of the puzzle that could be key to understanding whether previous Sars-CoV-2 infections – the virus behind Covid-19 – can prevent reinfection, and if so, for how long.
Emmanuelle Charpentier and Jennifer A Doudna will share the prize for genome editing method
Two women have been awarded the 2020 Nobel prize in chemistry for the discovery of the CRISPR genetic scissors used to edit the DNA of animals, plants and microorganisms with extremely high precision.
Emmanuelle Charpentier and Jennifer A Doudna will share the 10m Swedish kronor (£870,000) prize announced on Wednesday by the Royal Swedish Academy of Sciences in Stockholm – the first time that two women have shared the prize.
Several missions this year are seeking out life on the red planet. But would we recognise extraterrestrials if we found them?
In July, three unmanned missions blasted off to Mars – from China (Tianwen-1), the US (Nasa’s Mars 2020 Perseverance Rover) and the United Arab Emirates (Hope). The Chinese and American missions have lander craft that will seek signs of current or past life on Mars. Nasa is also planning to send its Europa Clipper probe to survey Jupiter’s moon Europa, and the robotic lander Dragonfly to Saturn’s moon Titan. Both moons are widely thought to be promising hunting grounds for life in our solar system – as are the underground oceans of Saturn’s icy moon Enceladus.
Meanwhile, we can now glimpse the chemical makeup of atmospheres of planets that orbit other stars (exoplanets), of which more than 4,000 are now known. Some hope these studies might disclose possible signatures of life.
Carlsberg and Coca-Cola back pioneering project to make ‘all-plant’ drinks bottles
Beer and soft drinks could soon be sipped from “all-plant” bottles under new plans to turn sustainably grown crops into plastic in partnership with major beverage makers.
A biochemicals company in the Netherlands hopes to kickstart investment in a pioneering project that hopes to make plastics from plant sugars rather than fossil fuels.
Helium hydride is thought to have played starring role in early universe
The most ancient type of molecule in our universe has been detected in space, scientists have revealed, backing up theories of how the early chemistry of the universe developed after the big bang.
The positively charged molecule known as helium hydride is believed to have played a starring role in the early universe, forming when a helium atom shared its electrons with a hydrogen nucleus, or proton. Not only is it thought to be the first molecular bond, and first chemical compound, to have appeared as the universe cooled after the big bang, but it also opened up the path to the formation of molecules of hydrogen.
Something strange is happening with a now-banned chemical that eats away at Earth's protective ozone layer: Scientists say there's more of it - not less - going into the atmosphere and they don't know where it is coming from. When a hole in the ozone formed over Antarctica, countries around the world in 1987 agreed to phase out several types of ozone-depleting chemicals called chlorofluorocarbons .
Imagine a scenario with no temperature difference between the equator and the North Pole. That was 12 million years ago when there was no ice at either pole.
Popular television shows such as the "Law & Order," "CSI" and "NCIS" franchises glorify forensic science as a magical, near-flawless tool for identifying criminals. Not surprisingly, Hollywood's depiction of forensic science needs a reality makeover.
Portsmouth Naval Shipyard is seeking 160 individuals with experience in industrial work and is hosting a job fair at the Regatta Conference Center in Eliot to help find them. The Tuesday, Nov. 14 job fair will be held from noon to 8 p.m. Public affairs officer Jeremy Lambert said the shipyard is looking to fill roughly 160 positions in fields such as chemistry, electrical work, engineering, insulation, mechanics, pipefitting, radiological work, sheet metal work and many others.
P arker Kittiwake launched the Parker Kittiwake Attenuated Total Reflection analyzer, which the company says represents a breakthrough for the simultaneous testing of base number , total acid number , insolubles, soot loading, viscosity, FAME and water content of oil samples on board a ship, allowing all parameters to be measured using a single sample in one test kit. The ATR analyzer uses infrared spectroscopy to determine the presence of damaging elements such as solid particles or water in a representative sample of oil.
"Both the atmosphere and the chemistry between the two leaders was positive, the posture between the two really set the tone", said Secretary of State Rex Tillerson. "We wanted to make you feel at home", Ms Trump can be heard saying in the clip.
Donald Trump and Chinese president Xi Jinping shake hands during their dinner at Mr Trump's Mar-a Lago resort in Florida Tillerson, who briefed reporters alongside Treasury Secretary Steven Mnuchin and Commerce Secretary Wilbur Ross at the conclusion of the summit, also said Trump said China needs to make changes to its economy in order to "level the playing field for American workers, stressing repeatedly the need for reciprocal market access". Trump aides, who participated in the two-day talks held at the US President's Mar-a-Lago resort in Florida, described the meetings as productive and said the two leaders exhibited "positive" chemistry.
It's been six months since Congress made major changes to the Toxic Substances Control Act , the law that governs the use of chemicals in industrial and household products in the U.S. One unanticipated outcome of the overhaul is a backlog of new chemicals waiting to be reviewed by the Environmental Protection Agency. Chemical manufacturers are up in arms about the delays, claiming EPA's slowness is impeding their innovation.
