Plastic pollution has entered the fossil record, research shows
Plastic pollution is being deposited into the fossil record, research has found, with contamination increasing exponentially since 1945.
Scientists suggest the plastic layers could be used to mark the start of the Anthropocene, the proposed geological epoch in which human activities have come to dominate the planet. They say after the bronze and iron ages, the current period may become known as the plastic age.

‘You oughta be in pictures,” goes the 1934 Rudy Vallée song. And, as of last week, pretty much anyone can be. The entry requirements for being a star fell dramatically thanks to the launch, in China, of a face-swapping app that can decant users into film and TV clips.
Zao, which has quickly become China’s most downloaded free app, fuses the face in the original clip with your features. All that is required is a single selfie and the man or woman in the street is transformed into a star of the mobile screen, if not quite the silver one. In other words, anyone who yearns to be part of Titanic or Game of Thrones, The Big Bang Theory or the latest J-Pop sensation can now bypass the audition and go straight to the limelight without all that pesky hard work, talent and dedication. A whole new generation of synthetic movie idols could be unleashed upon the world: a Humphrey Bogus, a Phony Curtis, a Fake Dunaway.

The European Space Agency has said it altered the trajectory of one of its observation satellites to avoid a collision with a craft operated by Elon Musk’s SpaceX.
“@ESA’s Aeolus Earth observation satellite fired its thrusters, moving it off a collision course with a @SpaceX satellite in their Starlink constellation,” the agency’s Twitter account said.

People who regularly consume soft drinks have a higher risk of an early death, researchers have found, with the trend seen for both sugared and artificially sweetened drinks.
While experts say the study cannot prove soft drinks are a driver of an increased risk of death, they say the work – which is the largest study of its kind – supports recent public health efforts to reduce consumption of soft drinks, such as the UK’s sugar tax.

The science of extending life is a subject of morbid fascination, conjuring the image of old billionaires being cryogenically frozen. But imagine if, instead of a pill you could take to live for ever, there was a pill that could push back the ageing process – a medicine that could stave off the fragility, osteoarthritis, memory loss, macular degeneration and cancers that plague old age.
It could happen, with the science of senolytics: an emerging – and highly anticipated – area of anti-ageing medicine. Many of the world’s top gerontologists have already demonstrated the possibilities in animals and are now beginning human clinical trials, with promising results. If the studies continue to be as successful as hoped, those who are currently middle-aged could become the first generation of oldies who are youthful for longer – with a little medical help.

Scientists say they have finally cracked the problem of repairing tooth enamel.
Though enamel is the hardest tissue in the body, it cannot self-repair. Now scientists have discovered a method by which its complex structure can be reproduced and the enamel essentially “grown” back.

It was one small step for man, one giant leap for Trumpkind.
Donald Trump made the short journey on Thursday from the Oval Office to the White House Rose Garden, then promised to unleash an army of space warriors to infinity and beyond.

The risk of breast cancer from using hormone replacement therapy is double what was previously thought, according to a major piece of research, which confirms that HRT is a direct cause of the cancer.
The findings of the definitive study will cause concern among the 1 million women in the UK and millions more around the world who are using HRT. It finds that the longer women take it, the greater their risk, with the possibility that just one year is risk-free. It also finds that the risk does not go away as soon as women stop taking it, as had been previously assumed.

A vast new study has quashed the idea that a single “gay gene” exists, scientists say, instead finding homosexual behaviour is influenced by a multitude of genetic variants which each have a tiny effect.
The researchers compare the situation to factors determining a person’s height, in which multiple genetic and environmental factors play roles.

Russia has unveiled a new space suit but the design may have to be changed to continue a decades-old tradition – making a stop to pee on the way to the launch.
The Sokol-M prototype suit was designed as a replacement for suits worn during launches to the International Space Station (ISS) on Soyuz spacecraft.

Archaeologists excavating what is thought to be the world’s largest child sacrifice site have unearthed the skeletons of 227 young victims in the coastal desert of northern Peru.
Teams have been digging since last year at the sacrificial site in Huanchaco, a beachside tourist town close to Trujillo, Peru’s third largest city.

Seeing the glass as half full may mean a longer life, according to research suggesting that optimists not only live longer in general, but have a better chance of reaching 85 or older.
It is not the first time optimism has been linked to health benefits. People of an upbeat disposition have previously been found to have a lower risk of heart conditions and premature death. Researchers now say it could also play a role in living a long life.
Continue reading...Experts find no proof minuscule particles are a threat to health but say more research is needed
Microplastics are increasingly found in drinking water, but there is no evidence so far that this poses a risk to humans, according to a new assessment by the World Health Organization.
However, the United Nations body warned against complacency because more research is needed to fully understand how plastic spreads into the environment and works its way through human bodies.

Even a small increase in light activity, such as washing dishes, a little gentle gardening, or shuffling around the house, might help stave off an early death among older adults, researchers say.
Being sedentary, for instance, by sitting for long periods of time, has been linked to an increased risk of developing many conditions, including heart disease, as well as an early death.

A new species of one of the most recognisable types of dinosaur is also the oldest of its kind ever discovered, British scientists believe.
Remains of a stegosaurus, an armoured dinosaur instantly recognisable by the plate-like bones protruding from its spine and spikes on its tails, were studied by a team from the Natural History Museum and belong to a new genus that walked the earth around 168m years ago.

Mathematicians, computer engineers and scientists in related fields should take a Hippocratic oath to protect the public from powerful new technologies under development in laboratories and tech firms, a leading researcher has said.
The ethical pledge would commit scientists to think deeply about the possible applications of their work and compel them to pursue only those that, at the least, do no harm to society.

In 2014, India sent the Mars Orbiter Mission into space, and became the first country to send a satellite to orbit the planet at its first attempt – putting its much richer regional rival China in the shade as it became the first Asian nation to get to the red planet. The project was notable for being led by a team of female scientists; as is India’s second lunar probe, Chandrayaan-2 (from the Sanskrit for “moon craft”), which was launched last month and is due to land on the moon in early September. And as the country establishes itself as a space power, Indians have developed an appetite for sci-fi themes in its cinema.
The patriotic outburst that followed the Mars mission has fuelled the latest example of Indian space cinema: Mission Mangal (Sanskrit for Mars), a fictionalised account of the Orbiter Mission. Starring and produced by Bollywood actor Akshay Kumar, it is due for release on 15 August, India’s Independence Day. “I would follow the news about India’s space missions and feel proud of what we were achieving,” says Kumar. “But through Mission Mangal I guess you could say I have an insider’s perspective.”

Ebola can no longer be called an incurable disease, scientists have said, after two of four drugs being trialled in the major outbreak in the Democratic Republic of the Congo were found to have significantly reduced the death rate.
ZMapp, used during the massive Ebola epidemic in Sierra Leone, Liberia and Guinea, has been dropped along with Remdesivir after two monoclonal antibodies, which block the virus, had substantially more effect, said the World Health Organization and the US National Institute of Allergy and Infectious Diseases, which was a co-sponsor of the trial.

Populations of the great beasts that once dominated the world’s rivers and lakes have crashed in the last 50 years, according to the first comprehensive study.
Some freshwater megafauna have already been declared extinct, such as the Yangtze dolphin, and many more are now on the brink, from the Mekong giant catfish and stingray to India’s gharial crocodiles to the European sturgeon. Just three Chinese giant softshell turtles are known to survive and all are male. Across Europe, North Africa and Asia, populations have plunged by 97% since 1970.

The ubiquitous use of war metaphors when referring to cancer may do more harm than good, according to research into the psychological impact the phrases have on people’s views of the disease.
Framing cancer in military terms made treatment seem more difficult and left people feeling more fatalistic about the illness, believing there was little they could do to reduce their risk, researchers found.
