Earliest evidence of cheese-making in the Mediterranean found along Croatian coast

Earliest evidence of cheese-making in the Mediterranean found along Croatian coast

Science
Sept. 5 (UPI) -- Scientists have discovered the earliest evidence of cheese-making in the Mediterranean along Croatia's Dalmatian Coast. Fatty residue left on the insides of ancient pottery suggests the people of the Middle Neolithic were making cheese as early as 7,200 years ago. "This pushes back cheese-making by 4,000 years," Sarah B. McClure, an associate professor of anthropology at Penn State University, said in a news release. As confirmed by the new analysis, the emergence of cheese-making corresponded with a shift in pottery technology. "Cheese production is important enough that people are making new types of kitchenware," said McClure. "We are seeing that cultural shift." During the Early Neolithic, populations along the Dalmatian Coast produced "impressed ware" pottery. But d...
Earliest evidence of humans outside Africa

Earliest evidence of humans outside Africa

Science
Scientists say they've found the earliest evidence of a human presence outside Africa.Ancient tools discovered in China suggest primitive humans were in the region as early as 2.12 million years ago.They are about 270,000 years older than the previous earliest evidence, which consists of bones and stone tools from Dmanisi in Georgia.The research, by a Chinese-British team, appears in the journal Nature.The stone artefacts were discovered at Shangchen on a plateau in northern China.They comprise different types of stone tools constructed for a variety of purposes. All show signs of having been used.Most were made of quartzite and quartz rock that probably came from the foothills of the Qinling Mountains, five to 10 km to the south of the dig site.But we do...
Study offers best evidence yet of an intermediate-mass black hole

Study offers best evidence yet of an intermediate-mass black hole

Science
June 18 (UPI) -- New data discovered by astronomers at the University of New Hampshire's Space Science Center offers the best evidence yet of the existence of intermediate-mass black holes, or IMBHs. Astronomers finally caught the elusive object devouring a star that drifted too close. Researchers imaged the consumption event using three different X-ray observatories, NASA's Chandra X-ray Observatory and Neil Gehrels Swift Observatory, as well as the European Space Agency's XMM-Newton. "We feel very lucky to have spotted this object with a significant amount of high quality data, which helps pinpoint the mass of the black hole and understand the nature of this spectacular event," Dacheng Lin, a research assistant professor at the Space Science Center, said in a news release. "Earlier res...

'Data breach': MP wants Zuckerberg to give evidence

Technology
Mark Zuckerberg will be asked to give evidence at a Commons committee examining allegations of unauthorised sharing of Facebook user data, an MP has said.Damian Collins, chair of the digital, culture, media and sport (DCMS) committee, said the Facebook chief executive must provide answers after an investigation alleged Cambridge Analytica, a British political campaigns firm, acquired and kept information about users."Data has been taken from Facebook users without their consent, and was then processed by a third party and used to support their campaigns," Mr Collins wrote on the House of Commons website."I will be writing to Mark Zuckerberg asking that either he, or another senior executive from the company, appear to give evidence in front of the Committee as part our inquiry."Image:Damia...
Teens using e-cigarettes show evidence of same toxic chemicals as smokers: Study

Teens using e-cigarettes show evidence of same toxic chemicals as smokers: Study

Health
Using e-cigarettes has been promoted as a way to help adult smokers cut back or quit smoking, or at least to minimize the health damage that smoking causes. Teens, even middle schoolers, have taken up e-cigarettes as well. But as researchers continue to study their safety, a new report in Pediatrics shows vaping could lead to the presence of concerning levels of toxic chemicals. Almost 100 teens from the San Francisco Bay area were examined in the University of California-San Francisco study: 67 teens used e-cigarettes only, 16 used both e-cigarettes and conventional cigarettes and 20 didn't smoke or vape at all. Urine and salivary gland testing looked for breakdown products of toxic chemicals that have been associated with cancer -- and found them in both smokers and vapers -- but not ...
