How are reptiles capable of generating such a diversity of bright colors? And how is it possible that within a single population of the same species, different individuals exhibit strikingly different coloration patterns? A team of scientists reveal two genes implicated in yellow to red pigmentation in reptiles, and demonstrate that these “pigmentation genes” also affect behaviour and other traits
Should public health-care systems provide couples with expanded screening for genetic disorders before they decide to become pregnant? Screening programmes could increase our reproductive choices and autonomy. But there are ethical issues at stake.
A world moving from fossil fuels to renewable energy will rely more and more on energy storage and in particular on batteries. The Battery 2030+ large-scale research initiative will gather leading scientists in Europe, as well as the industry, to achieve a leap forward in battery science and technology.
Uppsala Health Summit will offer up to four travel grants to journalists to attend the summit 7 - 9 October themed Healthy Urban Childhoods at Uppsala Castle, Sweden. The grant is intended for journalists with a demonstrated interest in the area, and who otherwise would not have the possibility to attend due to unavailability of funds. Last day to apply is 3 May 2019.
When antibiotics are used to treat bacteria susceptible to them, the treatment usually works. Nevertheless, the antibiotic chosen is sometimes ineffective. One of the reasons for this is heteroresistance, a phenomenon explored in depth by Uppsala and Emory University researchers in a new study.
Coprolites, or fossil droppings, of the dinosaur-like archosaur Smok wawelski contain lots of chewed-up bone fragments. This led researchers at Uppsala University to conclude that this top predator was exploiting bones for salt and marrow, a behavior often linked to mammals but seldom to archosaurs.
What do we need to be able to store carbon dioxide in bedrock and thereby reduce the human impact on the global climate? At the Celsius-Linnaeus lectures on 7 February, geologist Martin Blunt and microbiologist and toxicologist Linda S. Birnbaum will present research findings on some of the biggest challenges facing humanity.
Around 56 million years ago, global temperatures spiked. Researchers at Uppsala University and in the UK now show that a major explosive eruption from the Red Hills on the Isle of Skye may have been a contributing factor to the massive climate disturbance. Their findings have been published in the journal Scientific Reports.
A study from Uppsala University has found that whether you store your fat around the trunk or in other parts of your body is highly influenced by genetic factors and that this effect is present predominantly in women and to a much lower extent in men. In the study, published in Nature Communications, the researchers measured how fat was distributed in nearly 360,000 voluntary participants.
Uppsala University researchers have devised a new model for the Universe – one that may solve the enigma of dark energy. Their new article, published in Physical Review Letters, proposes a new structural concept, including dark energy, for a universe that rides on an expanding bubble in an additional dimension.
The critically endangered Grauer’s gorilla has recently lost genetic diversity and has experienced an increase in harmful mutations. These conclusions were reached by an international team of researchers who sequenced eleven genomes from eastern gorilla specimens collected up to 100 years ago, and compared these with genomes from present-day individuals. Results are published in Current Biology.
Isolated human hepatocytes are essential tools in preclinical and clinical liver research, but cell quality is highly variable. Now, researchers from Uppsala University have devised a simple protocol that improves hepatocyte quality and enables cells from a wider quality spectrum to be used in standard and advanced cell culture. The findings are published in Archives of Toxicology.
