A new study by researchers at the University of British Columbia (UBC) and BC Children’s Hospital shows the sugar sialic acid, which makes up part of the protective intestinal mucus layer, fuels disease-causing bacteria in the gut.  The findings, published in PNAS, suggest a potential treatment target for intestinal bacterial infections and a range of chronic diseases linked to gut bacteria, including inflammatory bowel disease (IBD), celiac disease, irritable bowel syndrome and short bowel syndrome.  “Bacteria need to find a place in our intestines to take hold, establish and expand, and then they need to overcome all the different defences that normally protect our ...

Rising global temperatures are making it harder for birds to know when it’s spring and time to breed according to a new study published in Proceedings of the National Academy of Sciences. A large collaboration led by scientists at UCLA and Michigan State University has found that birds produce fewer young if they start breeding too early or late in the season. With climate change resulting in earlier springlike weather, the researchers report, birds have been unable to keep pace. And, the authors write, the mismatch between the ...

When photosynthetic cells absorb light from the sun, packets of energy called photons leap between a series of light-harvesting proteins until they reach the photosynthetic reaction center. There, cells convert the energy into electrons, which eventually power the production of sugar molecules. This transfer of energy through the light-harvesting complex occurs with extremely high efficiency: Nearly every photon of light absorbed generates an electron, a phenomenon known as near-unity quantum efficiency. A new study from MIT chemists offers a potential explanation for how proteins of the light-harvesting complex, also called the antenna, achieve that ...

Until now, researchers have been unable to model how these deceptively simple tubular structures —called chemical gardens — work and the patterns and rules that ...

Gene expression within the apicoplast, an organelle in the malaria parasite Plasmodium falciparum, is regulated by melatonin (the circadian signaling hormone) in host blood, and intrinsic parasite cues, via a factor called ApSigma, as identified by a recent study aided by Tokyo Tech’s World Research Hub Initiative. The regulatory system highlighted in this study might be a future target for malaria treatment. Malaria is one of the biggest public health risks, with around 240 million people from across the globe contracting it every year. However, this life-threatening disease is ...

Regular physical exercise, such as resistance training, can prevent Alzheimer’s disease, or at least delay the appearance of symptoms, and serves as a simple and affordable therapy for Alzheimer’s patients. This is the conclusion of an article published in Frontiers in Neuroscience by Brazilian researchers affiliated with the Federal University of São Paulo (UNIFESP) and the University of São Paulo (USP). Although older people and dementia patients are unlikely to be able to do long daily runs or perform other high-intensity aerobic exercises, these activities are the focus for most scientific studies on ...

UPTON, NY—In the field of superconductivity—the phenomenon in which electrons can flow through a material with essentially zero resistance—the “holy grail” of discovery is a superconductor that can perform under everyday temperatures and pressures. Such a material could revolutionize modern life. But currently, even the “high-temperature” (high-Tc) superconductors that have been discovered must be kept very cold to function—too cold for most applications. Scientists still have much to learn before room-temperature ...

COLUMBIA, Mo. -- While formula-feeding babies is a safe and convenient option, research studies have shown natural breastfeeding is linked to numerous health benefits for both mother and child. For mothers, breastfeeding can improve recovery after giving birth and lower the risks of cancer. For babies, the nutrients strengthen their immune system and help lower their risk of developing obesity and diabetes. Now, a new study at the University of Missouri Sinclair School of Nursing is helping researchers better understand the factors that influence moms, particularly in rural areas where breastfeeding is less common, when deciding how to feed their babies. In the study, ...

People with dementia still have the ability to learn new things despite their illness. This is the conclusion of a doctoral thesis recently presented at Linköping University, Sweden. Its findings debunk the general belief that people with dementia are empty shells, according to Elias Ingebrand, who conducted the study. Elias Ingebrand let ten dementia sufferers, eight of whom lived in care facilities, try using computer tablets for the first time in their lives. A staff member or a loved one was there for support, but the only instruction given to participants ...

Summary An El Niño event has officially begun. The climate phenomenon, which originates in the tropical Pacific and occurs in intervals of a few years will shape weather across the planet for the next year or more and give rise to various climatic extremes. El Niño-like conditions can also occur on longer time scales of decades or centuries. This has been shown to have occurred in the recent past by an international research team led by Ana Prohaska of the University of Copenhagen and Dirk Sachse of the German Research Centre for Geosciences (GFZ). Their analysis of biomarkers – organic molecules or molecular fossils from vascular plants – in ...

(MEMPHIS, Tenn. – July 03, 2023) Gene therapy that alters hemoglobin genes may be an answer to curing sickle cell disease (SCD) and beta thalassemia. These two common life-threatening anemias afflict millions of individuals across the globe. Scientists at St. Jude Children’s Research Hospital and the Broad Institute of MIT and Harvard used a next-generation genome editing technology, adenosine base editing, to restart fetal hemoglobin expression in SCD patient cells. The approach raised the expression of fetal hemoglobin to higher, more stable, and more uniform levels than other genome editing technologies that use ...

MIAMI, FLORIDA (EMBARGOED UNTIL JULY 3, 2023 AT NOON ET) – The median length of survival after diagnosis of glioblastoma is 14 months, but some of these brain tumors are more aggressive and resistant to treatment than others, and a new study from Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine suggests reactivation of an ancient retrovirus may be at least partly to blame. “Our lab found that an evolutionary dormant retrovirus from 6 million years ago – HML-2, a subtype of HERV-K– contributes to brain tumor formation. We demonstrated for the first time that this virus, when reactivated, ...

Scientists have for the first time observed the early universe running in extreme slow motion, unlocking one of the mysteries of Einstein’s expanding universe. Einstein’s general theory of relativity means that we should observe the distant – and hence ancient – universe running much slower than the present day. However, peering back that far in time has proven elusive. Scientists have now cracked that mystery by using quasars as ‘clocks'. “Looking back to a time when the universe was ...

Our body’s fat metabolism plays a vital role in energy production in our body. A research team at the University of Basel, Switzerland, has discovered a molecular switch that regulates lipid metabolism in our cells. This switch controls the storage or conversion of lipids into energy. All organisms need energy to live. We get energy from various components of our food. Our body uses a part of this energy directly and stores the rest. While glucose serves as an immediately available energy source, fats are stored as energy reserve in form of lipid droplets within our cells. When the body needs energy from these fat stores, lipids are transported ...

Artificial intelligence can predict on- and off-target activity of CRISPR tools that target RNA instead of DNA, according to new research published in Nature Biotechnology. The study by researchers at New York University, Columbia Engineering, and the New York Genome Center, combines a deep learning model with CRISPR screens to control the expression of human genes in different ways—such as flicking a light switch to shut them off completely or by using a dimmer knob to partially turn down their activity. These precise gene controls could be used to develop new CRISPR-based therapies.  CRISPR is a gene ...
