The art of the Roman surveyors emerges from newly discovered pavements in Pompeii
A series of enigmatic images recently recovered in new excavations in Pompeii shed new light upon a fascinating figure of the Roman world: the Gromatics, the surveyours in charge of the regular division of the land and of town planning.
Through the eyes of animals
Humans are now closer to seeing through the eyes of animals, thanks to an innovative software framework developed by researchers from the University of Queensland and the University of Exeter.
Time to stop commercial distortion of healthcare evidence and practice, experts urge
It's time to stop the endemic financial entanglement with industry that is distorting the production and use of healthcare evidence, causing harm to individuals and waste for health systems, argue an influential group of international experts in The BMJ today.
Towards high quality ZnO quantum dots prospective for biomedical applications
Scientists from Warsaw together with colleagues from Grenoble have moved a step closer to creating stable, high quality colloidal zinc oxide quantum dots (ZnO QDs) for use in modern technologies and nanomedicine. Using advanced DNP-enhanced NMR spectroscopy they have clearly proved the superiority of the developed organometallic approach over the traditional sol-gel procedure both in terms of...
Transition to exhaustion: clues for cancer immunotherapy
Emory research on immune cells 'exhausted' by chronic viral infection provides clues on how to refine cancer immunotherapy. The Immunity paper defines a transitional stage in between stem-like and truly exhausted cells.
Two chiral catalysts working hand in hand
The stereoisomers of a molecule can cause different effects in a biological system, which is important for the development of drugs. Chemists at Münster University (Germany) have developed a synthetic method that can produce different stereoisomers from identical starting materials. The study appeared in 'Nature Catalysis'.
UMD astronomers catch a natural comet outburst in unprecedented detail
University of Maryland astronomers have made the most complete and detailed observations to date of the formation and dissipation of a naturally occurring comet outburst. Using data from NASA's Transiting Exoplanet Survey Satellite (TESS), the researchers gained a clear start-to-finish image sequence of an explosive emission of dust, ice and gases during the close approach to Earth of comet...
Unemployment encourages men to try traditionally female-dominated work
A study finds that men who previously worked in male-dominated or mixed-gender fields are significantly more likely to transition to female-dominated jobs following a bout of unemployment, bucking past evidence showing resistance by men to working female-dominated jobs. When they do make the switch, the study finds they reap benefits in wages and job prestige.
Virtual reality could help flu vaccination rates
Using a virtual reality simulation to show how flu spreads and its impact on others could be a way to encourage more people to get a flu vaccination, according to a study by researchers at the University of Georgia and the Oak Ridge Associated Universities in Oak Ridge, Tennessee.
VTT developed an optical fiber made of cellulose
VTT researchers were able to transmit light in wood-based fibre. Optical fibre made of cellulose is best suited for sensors that benefit from the biodegradability of the material. In the future, optical cellulose fibre may allow detecting changes in the moisture level of buildings.
What's driving erosion worldwide?
ETH Zurich researchers are reexamining the causes of soil erosion around the world -- and have found that countries themselves have a surprisingly strong influence on their soil. This country effect was previously undetected.
Women wearing hijabs in news stories may be judged negatively
Women wearing a veil or headscarf in the United States may face harsher social judgement, according to a study by Penn State researchers that found when given the same information in a news story, some people may consider a woman wearing a headscarf to be more likely to have committed a crime.
World first as artificial neurons developed to cure chronic diseases
Artificial neurons on silicon chips that behave just like the real thing have been invented by scientists -- a first-of-its-kind achievement with enormous scope for medical devices to cure chronic diseases, such as heart failure, Alzheimer's, and other diseases of neuronal degeneration.
Young children receiving housing vouchers had lower hospital spending into adulthood
Young children whose household received a housing voucher were admitted to the hospital fewer times and incurred lower hospital costs in the subsequent two decades than children whose households did not receive housing vouchers, according to a new study from researchers at Johns Hopkins Bloomberg School of Public Health.
Young tree swallows carry environmental stress into adulthood
Cornell University researchers have found that colder temperatures during tree swallows' development stage has an effect on swallows later in life.
Scientists show off unusually well-preserved prehistoric puppy
Russian scientists showed off a prehistoric puppy Monday, believed to be 18,000 years old, found in permafrost in the country's Far...
India's crashed Vikram moon lander spotted on lunar surface
Nasa satellite sends back images showing wreckage of Chandrayaan-2 mission, with debris found scattered nearly a kilometre awayA Nasa satellite orbiting the moon has found India’s Vikram lander, which crashed on the lunar surface in September, the US space agency said on Monday.Nasa released an image taken by its Lunar Reconnaissance Orbiter (LRO) that showed the site of the spacecraft’s...
'Toxic chemical cocktail' passed to baby porpoises
Potent chemicals are unwittingly passed down from mother to calf, according to a UK study.
Climate change: The COP25 talks trying to change the world
As the UN has its annual climate change conference, we look at what it's for and if it ever makes a difference.
Cyrus Biotechnology and CRISPR pioneers team up to boost gene-editing therapies
Seattle-based Cyrus Biotechnology says it'll collaborate with the Broad Institute of MIT and Harvard on ways to optimize CRISPR gene-editing techniques for use in developing novel human therapeutics. CRISPR has revolutionized genetics by making it easier to modify the DNA coding in the genome, but more needs to be done to address safety concerns for human applications. Cyrus Biotech and the...

Harbour porpoise calves around the UK are carrying a more neurotoxic cocktail of PCBs than their mothers, as females unknowingly detoxify themselves by transferring the chemicals while feeding their young, new research reveals today.
Making higher-energy light to fight cancer
- ScienceDaily
- 19/12/3 01:04
Researchers have achieved photon up-conversion, the emission of light with energy higher than the one that excites the material, using carefully designed structures containing silicon nanocrystals and specialized organic molecules. The accomplishment brings scientists one step closer to developing minimally invasive photodynamic treatments for cancer. The advance could also hasten new technologies...
Drone images show Greenland ice sheet becoming more unstable as it fractures
- ScienceDaily
- 19/12/3 01:04
The world's second-largest ice sheet, and the single largest contributor to global sea-level rise, is potentially becoming unstable because of fractures developing in response to faster ice flow and more meltwater forming on its surface.
Mystery of how early animals survived ice age

- 19/12/3 01:04
How did life survive the most severe ice age? A team has found the first direct evidence that glacial meltwater provided a crucial lifeline to eukaryotes during Snowball Earth, when the oceans were cut off from life-giving oxygen, answering a question puzzling scientists for years.
Helping machines perceive some laws of physics
