Non-nutritive sweeteners cause changes in the gut microbes and impact glucose tolerance

Since the late 1800s non-nutritive sweeteners have promised to deliver all the sweetness of sugar with none of the calories.

New resource can help researchers to assess how key genes control the differentiation of developing embryos

Years of work by developmental biologists from Trinity College Dublin, working with colleagues at the University of Edinburgh's MRC Human Genetics Unit, has yielded a resource of unparalleled detail that will help researchers assess how key genes control the differentiation of tissues and organs of developing embryos.

Researchers receive grant to develop purification membranes for large-scale manufacturing of viral vectors

With a $6 million grant from the National Science Foundation, researchers at the University of Arkansas and two partner institutions will develop purification membranes for future large-scale manufacturing of viral vectors and virus-like particles.

Researchers harness plasma-produced gas to activate plant immunity against wide-spread diseases

The flash of lightning and the dance of auroras contain a fourth state of matter known as plasma, which researchers have harnessed to produce a gas that may activate plant immunity against wide-spread diseases.

Study reveals the unique and unconventional way mosquitoes process odors

If you've ever sprayed yourself head to toe in bug repellent, yet still felt like a mosquito magnet, it will come as no shock to you that mosquitoes are very, very good at finding humans to bite.

Johns Hopkins Medicine researchers challenge the prevailing belief on how nasal cells process scent

Johns Hopkins Medicine researchers say they have evidence to potentially overturn a prevailing belief in a type of important signaling within cells.

Simple technique could be a powerful solution for disposing ‘forever chemicals’

PFAS, a group of manufactured chemicals commonly used since the 1940s, are called "forever chemicals" for a reason.

Researchers visualize antigen-bound T-cell receptor at atomic resolution

T cells are our immune system’s customized tools for fighting infectious diseases and tumor cells. On their surface, these special white blood cells carry a receptor that recognizes antigens.

Key gene sheds light on how people develop tolerance to pain-relievers over time

UF Scripps Biomedical Research scientists have a discovered a key gene that is shedding light on how people develop tolerance to pain-relievers over time, a problem that raises risk of addiction and overdose.

New study advances the understanding of genetic basis of autism

A new study of genes underlying neurodevelopmental differences has uncovered more than 70 that are very strongly associated with autism and more than 250 with strong links to the condition.

Sublethal exposure to insecticides impair optomotor behavior in bees

The challenge to let people walk back and forth in a straight line isn't just used by police to test if drivers are intoxicated: it's also used by neurologists to diagnose neurological disorders like ataxia, where parts of the brain that coordinate movement are impaired. Now, researchers use an insect version of this challenge to show for the first time that modern pesticides damage the nervous system of honeybees so that it becomes hard for them to walk in a straight line. The results are published in Frontiers in Insect Science.

Highly sensitive DNA test identifies neuroborreliosis in horses

A Rutgers scientist aiming to help heal a sick horse created an ultra-sensitive DNA test that could have applications for difficult-to-detect illnesses in humans such as Lyme disease.

Neurobiologists find few clues to why heat promotes midday sleep

On the hottest summer days, you may find yourself dozing off in the middle of the day. In some parts of the world, it's a cultural norm to schedule "siestas" and shutter businesses during the warmest hours of the day.

Immune cells preferentially use cellular waste products to power their function

The immune cells that protect us from infection and cancer seek out a wide array of fuel sources to power their function - including some long thought to be cellular waste products.

Researchers create novel mouse model for mapping protein communication between organs

Our many different organ systems are in constant communication with each other. During exercise, for example, muscles send out signals to fat and liver tissue to release their energy sources.

Research suggests a new model of how beige fat biogenesis is controlled

Once considered an inert tissue, fat – or adipose tissue – is now known to play an active role in the body's critical functions by secreting hormones that regulate hunger and body temperature.

Innovative technology revels the impact of environmental conditions on RNA structures in living cells

The impact of environmental conditions on the dynamic structures of RNAs in living cells has been revealed by innovative technology developed by researchers at the John Innes Centre.

New technique keeps the cells alive during RNA extraction

RNA sequencing allows scientists to study the expression of genes in a cell. Since messenger RNA (mRNA) is generated from a DNA gene, that information can be used to identify the original gene sequence and thus measure the activity of thousands of genes (i.e. the transcriptome) in these cells.

Scientists elucidate the structure of Type IV secretion system involved in antibiotic resistance

With antibiotic-resistant bacteria on the rise, scientists have been searching for ways to shut down the Type IV secretion system (T4SS), a protein complex on the outer envelope of bacterial cells that helps them to exchange DNA with neighboring bacteria and resist antibiotics.

Study identifies the link between a gene variant and protection against coronary atherosclerosis

The protective effect of the newly discovered variant against coronary heart disease is likely to be caused by the below-average arterial stiffness of variant carriers.
