A human-organs-on-chips technology has been used to microengineer a model of human intestinal inflammation and bacterial overgrowth in a human-gut-on-a-chip. The advance, say researchers, allows them for the first time t...

A new way detect early a potentially deadly fungal infection in patients with suppressed immune systems, such as those being treated for leukemia or have had an organ transplant, has been revealed by a team of scientists...

In the face of a flu epidemic, a one-size fits all vaccine strategy won't be effective, a new study has found. Instead, strategies need to change significantly depending on the characteristics of each region in Canada an...

State-of-the-art atomic force microscopes (AFMs) are designed to capture images of structures as small as a fraction of a nanometer -- a million times smaller than the width of a human hair. In recent years, AFMs have pr...

Unseasonably warm fall temperatures in the northeastern United States mean that blacklegged ticks (Ixodes scapularis), also known as deer ticks, are active later into December than is usually the case.

If light is able to propagate from left to right, the opposite direction is usually allowed as well. A beam of light can normally be sent back to its point of origin, just by reflecting it on a mirror. Researchers at TU ...

A childhood family breakup can have long-term negative consequences for the children. Recent research looks at overall health, depression, and smoking as a health-related behavior and finds that, for girls, all three are...

The presence or absence of the CAP2 gene causes sudden cardiac death in mice. In particular, the absence of the gene interrupts the animal's ability to send electrical signals to the heart to tell it to contract, a condi...

This phytoplankton bloom looks like a van Gogh painting.

The gene p53 has been described as the 'guardian of the genome' due to its prominent role in preventing genetic mutations. More than half of all cancers are thought to originate from p53 mutations or loss of function, an...

People with tinnitus who are less bothered by their symptoms use different brain regions when processing emotional information, new research indicates. Tinnitus, otherwise known as ringing in the ears, affects nearly one...

The first broad spectrum drug that can potently kill senescent (or aging) cells in culture, and effectively clear the cells in animals by specifically targeting a pathway that is critical for the survival of senescent ce...

Want to lose weight? Then make sure you're thinking about more than just the numbers on the scale when choosing your workout. A new study suggests that when people look forward to or back on an activity, they tend to und...

A novel way to enhance and restore cancer suppressor activity in B-cell acute lymphoblastic leukemia has been uncovered by researchers. This work results in better outcomes in a pre-clinical model of the disease.

Researchers compared mutation rates in sperm and eggs for multi-sibling families, confirming that fathers contribute more mutations to their children than mothers. They revealed for the first time that the rate at which ...

Researchers report their success in paradoxically inhibiting a process called NMD that cells have evolved to prevent imperfect proteins from being synthesized. Sometimes, it turns out, it's beneficial to allow protein sy...

RNs are more likely than LPNs to identify high-risk medication discrepancies, suggesting RNs are better equipped to assess and identify medication errors that could pose risks to residents' safety. These findings suggest...

Vitamin D plays a crucial role in ensuring appropriate bone density. Active individuals who enjoy participating in higher impact activities may need to maintain higher vitamin D levels to reduce their risk of stress frac...

The percentage of young adults in the United States who smoke cigarettes has dropped in recent years, but the decline could be due to this population switching from cigarettes to other forms of tobacco.

Insomniacs take heart: Humans get by on significantly less sleep than our closest animal relatives. The secret, according to a new study of slumber patterns across 21 species of primates, is that our sleep is more effici...

Scientists have developed an innovative way of using one of the biggest problems facing health services -- antibiotic resistance -- to develop drugs to combat some of the most intractable diseases.

Drug-induced changes to the gut microbiome can cause obesity by reducing the resting metabolic rate -- the calories burned while sleeping or resting -- a new study in mice demonstrates.
