Research reveals potential treatment to prevent obesity-driven liver damage
Research team from Cincinnati Children's reports that excessive fat deposition in the liver due to obesity can alter the microenvironment of the liver in a way that attracts a highly specific population of immune T cells to the liver. These cells help trigger NAFLD.
Researchers call for bias-free artificial intelligence
Medical devices employing AI stand to benefit everyone in society, but if left unchecked, the technologies could unintentionally perpetuate sex, gender and race biases.
Researchers develop algorithm to see inside materials with subatomic particles
The University of Kent's School of Physical Sciences, in collaboration with the Science and Technology Facilities Council (STFC) and the Universities of Cardiff, Durham and Leeds, have developed an algorithm to train computers to analyse signals from subatomic particles embedded in advanced electronic materials.
Researchers identify 64 regions of the genome that increase risk for bipolar disorder
International consortium of leading psychiatric genetics scientists studied thousands of DNA sequences, more than doubling the number of regions previously identified
Researchers identify proteins that predict future dementia, Alzheimer's risk
The development of dementia, often from Alzheimer's disease, late in life is associated with abnormal blood levels of dozens of proteins up to five years earlier.
Researchers reveal new tool to help prevent suicide
A team of Welsh academics has developed a new method of supporting health professionals to make clinical decisions about people who may be at risk of taking their own lives.
Researchers: No added risk of death with drug-coated devices used for lower body procedure
Cardiologists at Beth Israel Deaconess Medical Center (BIDMC), designed the Safety Assessment of Femoropopliteal Endovascular Treatment With Paclitaxel-coated Devices (SAFE-PAD) study to provide the information necessary to make scientifically-sound regulatory decisions about the safety of these devices.
Routine testing before surgery remains common despite low value
Before undergoing surgery, patients often go through a number of tests: blood work, sometimes a chest X-ray, perhaps tests to measure heart and lung function.In fact, about half of patients who had one of three common surgical procedures done in Michigan between 2015 and the midway point of 2019 received at least one routine test beforehand.Yet plenty of evidence suggests that preoperative testing...
Sacubitril/valsartan not superior to valsartan for advanced heart failure
Patients with heart failure with reduced ejection fraction (HFrEF) did not have better health outcomes if they took sacubitril/valsartan combination therapy compared with valsartan alone, according to new data presented at the American College of Cardiology's 70th Annual Scientific Session.
Save our oceans to protect our health - scientists call for global action plan
An interdisciplinary European collaboration called the Seas Oceans and Public Health In Europe (SOPHIE) Project, led by the University of Exeter and funded by Horizons 2020, has outlined the initial steps that a wide range of organisations could take to work together to protect the largest connected ecoInsystem on Earth. They call for the current UN Ocean Decade to act as a meaningful catalyst for...
Scientists explain why climate models can't reproduce the early-2000s global warming slowdown
The unexpected global warming slowdown during 1998-2013 challenges the simulation ability of climate models since most models participating in phase 5 of the Coupled Model Intercomparison Project (CMIP5) cannot simulate it. The CMIP6 with the most advanced climate models is now underway. Researchers evaluated the ability of the new-generation CMIP6 climate models on simulating the warming...
Scientists explore Tesla roads not taken -- and find new potential present-day utility
A valve invented by engineer Nikola Tesla a century ago is not only more functional than previously realized, but also has other potential applications today, a team of researchers has found after conducting a series of experiments on replications of the early 20th-century design.
Scientists find new way of predicting COVID-19 vaccine efficacy
he early immune response in a person who has been vaccinated for COVID-19 can predict the level of protection they will have to the virus over time, according to analysis from Australian mathematicians, clinicians, and scientists, and published today in Nature Medicine.
Scientists shed light on the mechanism of photoactivation of the orange carotenoid protein
It is a photoreceptor of cyanobacteria which protects them from excessive exposure to light. The design and production of a mutant variant of OCP and exploitation of state-of-the-art spectroscopic approaches made it possible to describe a photochemcial reaction that is new for carotenoids. These results will open up prospects for the development of new light-controlled systems and biomaterials.
Shortcut for dendritic cells
During an inflammatory response, things need to happen quickly: ETH Zurich researchers have recently discovered that certain immune cells that function as security guards can use a shortcut to get from the tissue to lymph nodes.

Skoltech researchers developed an enriched method for increasing the capacity of next-generation metal-ion battery cathode materials
Scientists at Skoltech Center for Energy Science and Technology have developed an enriched and scalable approach for increasing the capacity of a broad range of metal-ion battery cathode materials. An important advantage of the approach is its scalability. The process requires no sophisticated conditions and is relatively safe. Additionally, the reducing agents can be recycled after they react...
Slow research to understand fast change
A new open-access research collection published in Ecosphere reveals unexpected lessons drawn from decades of rich data from the Long Term Ecological Research (LTER) Network.
Some RNA molecules have unexpected sugar coating
Sugars attach to certain RNA molecules on the outside membrane of the cell. The newly discovered "glycoRNAs" may be involved in immune signaling.
Sotagliflozin shows benefit for difficult-to-treat form of heart failure
Patients with both diabetes and heart failure who were treated with sotagliflozin, a novel investigational drug for diabetes, for a median of nine to 16 months experienced reductions of 22% to 43% in the risk of death or worsening heart failure compared with similar patients who were treated with a placebo, according to research presented at the American College of Cardiology's 70th Annual...
Stair climbing offers significant cardiovascular and muscular benefits for heart patients
A team of McMaster University researchers who studied heart patients found that stair-climbing routines, whether vigorous or moderate, provide significant cardiovascular and muscular benefits.
Stanford study reveals new biomolecule
A newfound biomolecule, consisting of RNA modified by sugars, could be present in all forms of life and might contribute to autoimmune disease.
Study reveals new options to help firms improve the food recall process
New research from the University of Notre Dame helps to close the gap between what is and isn't known about food recalls.
Study shows early preterm births can be decreased with DHA supplementation
Early preterm births may be dramatically decreased with docosahexaenoic acid (DHA) supplements, with a dose of 1000 mg more effective for pregnant women with low DHA levels than the 200 mg found in some prenatal supplements.
Supermassive black holes devour gas just like their petite counterparts
Supermassive black holes devour stellar material just like their more petite counterparts, an MIT study finds.
