Two distinct pathways leading to the development of septic shock pave the way for personalized medicine in sepsis
Diagnostics company SphingoTec GmbH announced today that two distinct processes are involved in the development of septic shock and that SphingoTec's biomarkers for endothelial function (vascular integrity) and cardiovascular depression allow early identification of these underlying mechanisms requiring different interventions.
UCI researchers eavesdrop on cellular conversations
An interdisciplinary team of biologists and mathematicians at the University of California, Irvine has developed a new tool to help decipher the language cells use to communicate with one another. In a paper published today in Nature Communications, the researchers introduce CellChat, a computational platform that enables the decoding of signaling molecules that transmit information and commands...
UCLA study finds combination therapy suppresses pancreatic tumor growth in mice
UCLA Jonsson Comprehensive Cancer Center researchers have uncovered a potential new way to target pancreatic tumors that express high intratumoral interferon signaling (IFN).
Ultrafast electron dynamics in space and time
Often depicted as colourful balloons or clouds, electron orbitals provide information on the whereabouts of electrons in molecules, a bit like fuzzy snapshots. In order to understand the exchange of electrons in chemical reactions, it is not only important to know their spatial distribution but also their motion in time. Scientists from Julich, Marburg, and Graz have now made huge progress in this...
Ultraviolet 'television' for animals helps us better understand them
University of Queensland scientists have developed an ultraviolet 'television' display designed to help researchers better understand how animals see the world.
UNEP synthesis of scientific assessments provides blueprint to secure humanity's future
The UN Secretary-General and Executive Director of UNEP launch "Making Peace with Nature," a year-long synthesis of major UN scientific assessments. This summary underscores the level of emergency documented and reveals an intersection of common conclusions that clearly identify core policy change priorities.The new report also prescribes priority actions required of every major...
Unexpected decrease in ammonia emissions due to COVID-19 lockdowns
Scientists introduced machine learning algorithms to models that separated meteorological influences and confirmed that the actual atmospheric ammonia concentration dropped to a new minimum during the 2020 Spring Festival at both urban and rural sites.
UNH researchers release child maltreatment report showing mixed trends
A new report from the University of New Hampshire's Crimes against Children Research Center (CCRC) showed a mixed trend in child maltreatment with marked increase in child abuse fatalities but also declines in physical abuse and neglect in 2019.
Unique feeding behavior of Asian kukri snakes gutting frogs and toads
After describing a novel behaviour of the Small-banded Kukri Snake last September, two new studies, also led by Henrik Bringsøe, now report the same gruesome feeding strategy - where the snakes pierce the abdomen of frogs or toads to swallow their organs, as the prey remains alive for up to a few hours - in another two species: the Taiwanese Kukri Snake and the Ocellated Kukri Snake. The...
Which suicide prevention strategies work?
Columbia University researchers have found that suicide deaths can be reduced by a Federally coordinated approach employing scientifically proven options.
Wolves prefer to feed on the wild side
When there is a choice, wolves in Mongolia prefer to feed on wild animals rather than grazing livestock. This is the discovery by a research team from the University of Göttingen and the Senckenberg Museum Görlitz. Previous studies had shown that the diet of wolves in inland Central Asia consists mainly of grazing livestock, which could lead to increasing conflict between nomadic livestock...
New baby orca born to southern resident killer whale community
The Center for Whale Research in Washington state confirms a baby orca has been born to L pod, one of three family groups that make up the West Coast's endangered southern resident killer whale...
Impact of COVID-19 in Africa 'vastly underestimated', warn researchers

The impact of COVID-19 in Africa has been vastly underestimated, warn researchers in a new study that showed that COVID-19 deaths accounted for 15 to 20 percent of all sampled deaths -- many more than official reports suggest and contradicting the widely held view that COVID-19 has largely skipped Africa and had little impact.
UK hospital admissions for food-induced anaphylaxis triple over 20 year period but death rate falls

The rate of people who are admitted to hospital in the UK due to a serious allergic reaction (anaphylaxis) caused by food has more than tripled over a 20-year period. Despite this, the death rate from food-induced anaphylaxis halved over the same period, according to new research.
Damage to the heart found in more than half of COVID-19 patients discharged from hospital

Around 50 percent of patients who have been hospitalized with severe COVID-19 and who show raised levels of a protein called troponin have damage to their hearts. The injury was detected by magnetic resonance imaging (MRI) scans at least a month after discharge, according to new findings.
Never-before-seen antibody binding, informing liver cancer, antibody design
- ScienceDaily
- 21/2/18 02:40
In structural biology, some molecules are so unusual they can only be captured with a unique set of tools. That's precisely how a team defined how antibodies can recognize a compound called phosphohistidine -- a highly unstable molecule that has been found to play a central role in some forms of cancer.
Texas weather: Are frozen wind turbines to blame for power cuts?
Frozen wind turbines are being blamed for power failures - but problems with fossils fuels are a bigger issue.
Nasa Perseverance rover: How this Mars landing will be different
Nasa's Perseverance rover is aiming for Jezero Crater, considered “too dangerous” for previous spacecraft.
