Two newly discovered mechanisms in bacteria have been identified that can contribute to the development of antibiotic resistance. Changing the number of copies of resistance genes in bacteria increases antibiotic resistance. These two mechanisms, along with a third known mechanism, can occur independently of each other, even within the same bacterial cell. (published in Nature Communications)
Research at Uppsala University and Karolinska Institutet could pave the way for a prosthetic hand and robot to be able to feel touch like a human hand. Their study has been published in the journal Science. The technology could also be used to help restore lost functionality to patients after a stroke.
Uppsala University Museum Gustavianum and the Museum of Fine Arts, Boston have reached an agreement on the return of an ancient Egyptian ceramic child sarcophagus, dated to the 19th Dynasty (1295–1186 BC). The sarcophagus belonged to a boy named Pa-nefer-neb.
A computer game helped upper secondary school students become better at distinguishing between reliable and misleading news. This is shown by a study conducted by researchers at Uppsala University and elsewhere. “The students improved their ability to identify manipulative techniques in social media posts and to distinguish between reliable and misleading news,” says Professor Thomas Nygren.
New screening tools in child health care are effective in identifying early language and communication difficulties in children. This is shown by two studies based on more than 6,000 children carried out by researchers at Uppsala University in cooperation with Region Gotland.
Scientists at Uppsala University have discovered a new class of antibiotics with potent activity against multi-drug resistant bacteria, and have shown that it cures bloodstream infections in mice. The new antibiotic class is described in an article in the scientific journal PNAS.
Researchers have discovered that bank voles in Skåne, southern Sweden, carry a virus that can cause hemorrhagic fever in humans. This finding was made more than 500 km south of the previously known range. This is revealed in a new study from Uppsala University. The researchers were surprised that such a high proportion of the relatively few voles they caught were actually carrying a hantavirus.
In a new book, experts in a variety of fields explore nocebo effects – how negative expectations concerning health can make a person sick. It is the first time a book has been written on this subject.
A new study shows how heteroresistance, a transient resistance common in many bacteria, can act as a precursor to the development of antibiotic resistance. According to researchers at Uppsala University, this is the first time this link has been demonstrated.
The EU and OECD have jointly developed rules to prevent companies from exploiting differences in national legislation for financial gain. According to a new thesis/study at Uppsala University, however, companies are able to circumvent the rules. “The losers are mainly developing countries that are not members of the EU or OECD," explains Autilia Arfwidsson, doctoral student in Law.
Women with a type of ovarian cancer known as germ cell tumours have a worse prognosis than men with similar tumours, i.e. testicular cancer. After five years with the disease, 98 percent of men were alive while the survival rate for women was only 85 percent. This has been revealed by a new study from Uppsala University and Uppsala University Hospital published in the Journal of Internal Medicine.
Despite marine sponges being widespread on our planet, their biodiversity and distribution is still poorly known. Even though the Mediterranean Sea is the most explored sea on Earth, a study by Díaz et al. (2024) reveals the presence of new sponge species and new records in unexplored habitats such as underwater caves or mountains around the Balearic Islands.
