What the cranium of oldest human ancestor would have looked like
Despite having lived about 300,000 years ago, the oldest ancestor of all members of Homo sapiens had a surprisingly modern skull, as suggested by a model created by CNRS researcher Aurélien Mounier of the Histoire Naturelle de l'Homme Préhistorique laboratory (CNRS / Muséum National d'Histoire Naturelle) and Cambridge University professor Marta Mirazón Lahr. After comparing the virtually...

Do animals control earth's oxygen level?
- ScienceDaily
- 19/9/10 16:54
For the first time, researchers have measured how the production of algae and the Earth's oxygen level affect each other -- what you might call 'Earth's heartbeat'. Studies of 540 million-year-old limestone indicate that it is not just the oxygen level that affects animals, but that animals can indeed regulate the oxygen level.
Chronic enteroviral infection modifies broadly pancreatic cellular functions
- ScienceDaily
- 19/9/10 16:53
Enteroviral infections are common viral infections with usually rather few symptoms and also believed to be linked to the onset of type 1 diabetes. Type 1 diabetes is a disorder in which the pancreatic insulin-producing beta-cells are destroyed. A new study supports the link between enteroviral infections and type 1 diabetes.
Colorful microreactors utilize sunlight
- ScienceDaily
- 19/9/10 16:53
The sun is the most sustainable energy source available on our planet and could be used to power photochemical reactions. Scientists now present a widely applicable, cost-effective photomicroreactor. It is based on ''Luminescent Solar Concentrators'', which harvest, convert, and make photons available for chemical reactions. Thus, the researchers were able to synthesize various substances,...
Earliest evidence of milk consumption found in teeth of prehistoric British farmers
- ScienceDaily
- 19/9/10 16:53
Archaeologists have identified a milk protein called beta lactoglobulin (BLG) entombed in the mineralized dental plaque of seven individuals who lived in the Neolithic period around 6,000 years-ago.
Adolescents with high levels of physical activity perform better in school over two years

Adolescents with higher levels of physical activity performed better in school during transition from primary school to lower secondary school than their physically inactive peers.
Archaeological team excavates at one of the major fortress-settlements in the Armenian Highlands
A team of researchers and students from HKU unearthed huge storage jars, animal bones and fortress walls from 3,000 years ago in Armenia as they initiated the Ararat Plain Southeast Archaeological Project (APSAP) during the summer of 2019.
How Bullying May Shape Adolescent Brains
In recent years, a steadily increasing volume of data has demonstrated that peer victimization — the clinical term for bullying — impacts hundreds of millions of children and adolescents, with the effects sometimes lasting years and, possibly, decades. The problem is even recognized as a global health challenge by the World Health Organization and the United Nations. And yet,...
The danger of heat and cold across Australia
Cold temperatures are not nearly as deadly as heat, with around 2% of all deaths in Australia related to heat, according to new research from the University of Technology Sydney.
Global trade of tree seeds can introduce harmful pests
The trade of forest tree seeds is, on a global scale, not as safe as previously believed. Researchers from CABI and, among other institutions, the Swiss Federal Institute WSL, revealed that insect pests and fungal pathogens associated with seeds pose a great risk to trees and forest ecosystems worldwide.
New report reveals 'epidemic' levels of crime in shops
A hard-hitting new report calls on action to stem the rising number of crimes against shop workers, which has hit a five-year high, and highlights workers suffering with post-traumatic stress disorder, more commonly seen in the armed forces.
Optical vacuum cleaner can manipulate nanoparticles
Scientists at Tomsk Polytechnic University jointly with Russian and international colleagues developed the concept for constructing an "optical vacuum cleaner." Due to its optical properties, it can trap nanoparticles from the environment. Currently, there are no effective devices for this task. The research results were published in Scientific Reports. In the future, such "vacuum cleaners" can be...
Raising a glass to grapes' surprising genetic diversity
Here's a discovery well worth toasting: A research team led by Professor Brandon Gaut with the University of California, Irvine and Professor Dario Cantu with the University of California, Davis has deciphered the genome of the Chardonnay grape. By doing so, they have uncovered something fascinating: grapes inherit different numbers of genes from their mothers and fathers. Their paper has just...
Making biopsies less invasive and more informative
- ScienceDaily
- 19/9/10 16:21
A team of researchers has developed a novel technology that could sensitively and accurately detect and classify cancer cells, as well as determine the disease aggressiveness from the least invasive biopsies. With this new technology called STAMP (Sequence-Topology Assembly for Multiplexed Profiling), comprehensive disease information can be obtained faster, at a much earlier stage of the clinical...
Survey shows many primary care doctors are unprepared to help patients avoid diabetes

Breeders release new flaxseed cultivar with higher yield
The small but mighty flaxseed has many health benefits for humans, as well as other important uses. Yield, and therefore profits, are important for the few farmers who grow it in the United States.

Are black holes made of dark energy?
Two University of Hawaii at Manoa researchers have identified and corrected a subtle error that was made when applying Einstein's equations to model the growth of the universe.
Study finds parole 'a roll of the dice' for those convicted as teens
A review of parole-hearing transcripts since California's juvenile justice reform law took effect in 2014 found that black people in prison who were convicted as teenagers, especially those without private attorneys, had a low likelihood of gaining parole.
Science and Star Wars
Might popular culture, such as the Star Wars science fiction franchise be used to boost skills among those involved in STEM (science, technology, engineering, and mathematics)? Writing in the International Journal of Social Media and Interactive Learning Environments, Stephan Längle of the Danube University Krems in Austria discusses the possibility.
Study explores role of mediator protein complex in transcription and gene expression
Did you know that the DNA in any cell of the human body—or any organism for that matter—contains the genetic information required to develop every possible type of cell within that organism? Yet cell types differ markedly from each other both structurally and functionally. This is manifest through the production of different proteins encoded in the genetic information of the cell.
Researchers unveil new volcanic eruption forecasting technique
Volcanic eruptions and their ash clouds pose a significant hazard to population centers and air travel, especially those that show few to no signs of unrest beforehand. Geologists are now using a technique traditionally used in weather and climate forecasting to develop new eruption forecasting models. By testing if the models are able to capture the likelihood of past eruptions, the researchers...
