Can the field of archaeology "pass the spade" to locals to manage cultural heritage?
The separation of physical from intellectual work on archaeological sites has persisted throughout the nearly 200 years of archaeological fieldwork in the Middle East, according to Allison Mickel, a professor of anthropology in Lehigh University's Department of Department of Sociology & Anthropology. Mickel, who conducts research on the role local communities have played in archaeological work in...

'Deepfakes' ranked as most serious AI crime threat
Fake audio or video content has been ranked by experts as the most worrying use of artificial intelligence in terms of its potential applications for crime or terrorism, according to a new UCL report.
Surface clean-up technology won't solve ocean plastic problem
Clean-up devices that collect waste from the ocean surface won't solve the plastic pollution problem, a new study shows.
Disposed PPE could be turned into biofuel, study shows
Plastic from used personal protective equipment (PPE) can, and should, be transformed into renewable liquid fuels—according to a new study, published in the peer-reviewed Taylor & Francis journal Biofuels.
Grooming behavior between dairy cows reveals complex social network
Like humans, cattle are social creatures with complex relationships that change as group dynamics evolve. A study published in Frontiers in Veterinary Science offered new insights into the social networking behavior of dairy cows, building on a body of research that could someday help reshape farm management practices to create healthier living environments for the animals.
Ancient shell llama offering found in lake Titicaca
A llama carved from a spondylus shell and a cylindrical laminated gold foil object were the contents of a carved stone box—an offering—found at the bottom of Lake Titicaca, according to researchers from Penn State and the Université libre de Bruxelles, Belgium. The offering, found near an island in the lake, was not located where others had found offerings in the past.
Malignant cancer diagnosed in a dinosaur for the first time
A collaboration led by the Royal Ontario Museum (ROM) and McMaster University has led to the discovery and diagnosis of an aggressive malignant bone cancer—an osteosarcoma—for the first time ever in a dinosaur. No malignant cancers (tumours that can spread throughout the body and have severe health implications) have ever been documented in dinosaurs previously. The paper was published August...

1st big Southern California wildfire of 2020 keeps on raging
A huge wildfire in mountains east of Los Angeles that is Southern California's biggest blaze so far this year was still raging Monday, with thousands of people forced to evacuate their homes.
Humans and flies employ very similar mechanisms for brain development and function
With these new findings scientists can potentially better understand the subtle changes that can occur in genes and brain circuits that can lead to mental health disorders such as anxiety and autism spectrum disorders.
Hydrogel paves way for biomedical breakthrough
Published in Advanced Functional Materials, a University of Sydney team of biomedical engineers has developed a plasma technology to robustly attach hydrogels—a jelly-like substance which is structurally similar to soft tissue in the human body—to polymeric materials, allowing manufactured devices to better interact with surrounding tissue.
Monkeying around: Study finds older primates father far fewer babies
Infertility is a worldwide clinical problem for human health that affects 8 to 12 percent of couples. A new study from Washington University in St. Louis has implications for understanding some age-related aspects of male reproductive health in primates, including humans.
New research sheds light on bargaining and the 'daily deal market'
If you've ever taken advantage of a nice discount thanks to a promotion from Groupon or LivingSocial, you've tapped the power of the daily deal market yourself. You, the consumer, benefited from the prior bargaining that took place between that big online platform and the merchant, resulting in a lower price for you.
Researchers investigate effect of COVID-19 on UK organized crime
The effects of COVID-19 on Child Criminal Exploitation (CCE) are being investigated by the Rights Lab at the University of Nottingham, UK.
NASA obtains satellite imagery on Tropical Storm Isaias
NASA's Aqua satellite obtained visible and water vapor imagery as Tropical Storm Isaias continued moving along the east coast of Florida. On Aug. 3, Warnings and Watches stretched from Florida to Maine.
Study shows demolishing vacant houses can have positive effect on neighbor maintenance
New research suggests that demolishing abandoned houses may lead nearby property owners to better maintain their homes.
Semiconductor manufacturing techniques employed for new gamma-ray detector
NASA astrophysicists and engineers are adapting detectors used by earthbound supercolliders and creating them the same way electronics companies produce all modern consumer devices, including cell phones and laptops.
NASA satellites show two views of California's Apple Fire
NASA's satellites were working overtime as they snapped pictures of the large Apple Fire in Banning Canyon near San Bernardino, California on Aug. 02, 2020. This fire began on July 31, 2020 and the cause of the fire is still under investigation. To date the fire has consumed 20,516 acres and is 5% contained.
Researchers discover how chlamydiae multiply in human cells
Chlamydia are bacteria that cause venereal diseases. In humans, they can only survive if they enter the cells. This is the only place where they find the necessary metabolites for their reproduction. And this happens in a relatively simple way: The bacteria create a small bubble in the cell and divide in it over several generations.
Researchers collaborate on a strategy for sustainable aquaculture, the world's fastest growing food sector
As the population grows, and the global standard of living improves, humanity's appetite for seafood is increasing. In 2020 seafood consumption reached an all-time high, with an average of 20kg consumed annually by every person on the planet.
AI and single-cell genomics: New software predicts cell fate
Traditional single-cell sequencing methods help to reveal insights about cellular differences and functions—but they do this with static snapshots only rather than time-lapse films. This limitation makes it difficult to draw conclusions about the dynamics of cell development and gene activity. The recently introduced method 'RNA velocity' aims to reconstruct the developmental trajectory of a...
