Structures Discovered in Brain Cancer Patients Can Help Fight Tumors
Researchers at Uppsala University have discovered lymph node-like structures close to the tumor in brain cancer patients, where immune cells can be activated to attack…
New Species of Beetle Discovered in Dinosaur Ancestor’s 230 Million-Year-Old Poop
The tiny beetle Triamyxa coprolithica is the first-ever insect to be described from fossil feces. The animal the researchers have to thank for the excellent…
Purging Bad Mutations: Males Help Keep Populations Genetically Healthy
A few males are enough to fertilize all the females. The number of males, therefore, has little bearing on a population’s growth. However, they are…
Earth’s Mantle Provides New Clues To Explain Indonesia’s Explosive Volcanoes
Indonesia’s volcanoes are among the world’s most dangerous. Why? Through chemical analyses of tiny minerals in lava from Bali and Java, researchers from Uppsala University…
Entire Genome From Peştera Muierii 1 Sequenced – 35,000 Year-Old Romanian Skull
For the first time, researchers have successfully sequenced the entire genome from the skull of Peştera Muierii 1, a woman who lived in today’s Romania…
Molecular Biologists Travel Back in Time – Over 3 Billion Years
A research group working at Uppsala University has succeeded in studying ‘translation factors’ – important components of a cell’s protein synthesis machinery – that are…
Newly Discovered Immune Cell Function Vital to Healing May Lead to Treatments for Cancer and Cardiovascular Diseases
Cardiovascular disease, the most common cause of death, is the result of oxygen deprivation as blood perfusion to affected tissue is prevented. To halt the…
Largest-Ever DNA Mapping of the Philippines Shows 5 Major Immigration Waves Over 50 Millennia
Over 50 millennia, at least five major immigration waves have successively populated the Philippines, the most comprehensive survey of genetic variations in the country to…
First 3D Sound-Frequency Map for Inner Ear Created With Advanced X-ray Technology
Researchers at Uppsala University have created the first 3D map of the hearing nerve showing where the various sound frequencies are captured. Using what is…
Study Finds Limited Transmission of COVID-19 From Open Schools
Most countries introduced school closures during the spring of 2020 despite substantial uncertainty regarding the effectiveness in containing SARS-CoV-2. In Sweden, upper-secondary schools moved online…
Bioinformatic Analysis Offers New Clues to How SARS-CoV-2 Infects Cells
The molecular details of how SARS-CoV-2 enters cells and infects them are still not clear. Researchers at Uppsala University have tested the bioinformatic predictions made…
Answers on When and How the First Animals Appeared From 500 Million-Year-Old Microfossils
When and how did the first animals appear? Science has long sought an answer. Uppsala University researchers and colleagues in Denmark have now jointly found,…
Genetic Sequencing of 240 Mammals to Help Identify the Mutations That Lead to Human Diseases
A large international consortium led by scientists at Uppsala University and the Broad Institute of MIT and Harvard has sequenced the genome of 130 mammals…
