Virtual rocks: A new spin on virtual geology

Over the past decade, the number of virtual field trips created to simulate in-person field excursions has grown, but one aspect of physical fieldwork is not commonly replicated: Virtual explorers do not often return to their desks with collections of virtual rocks. Show More Summary

How Australian giant cuttlefish react to threats

Male cuttlefish do not bluff. When their body language shows they are agitated, they are. This was one of the findings from a study on the giant Australian cuttlefish.

Confronted with sepsis, key immune mechanism breaks, scientists find

When the body encounters an infection, a molecular signaling system ramps up the body's infection-fighting system to produce more white blood cells to attack invading bacteria. Now researchers have discovered that when facing a massive bacterial infection resulting in sepsis, that same signaling system malfunctions, damaging the body's ability to fight the invaders.

Websites with history can be just as conversational as chatting with a person

A website with search and interaction history can be just as engaging as chatting with an online human agent, or robot helper, according to researchers.

Researchers discover gene variant associated with esophageal cancer

A rare genetic mutation is associated with susceptibility to familial Barrett esophagus and esophageal cancer, according to a new study that set out to identify novel disease susceptibility variants in FBE in affected individuals from a large multigenerational family.

Even mild vision impairment has influence on quality of life

Blindness is known to have a broad-ranging adverse influence on affected individuals, their families, and the societies in which they live and is exemplified by its association with impaired quality of life, worse general and mental health, curtailed life chances, and increased all-cause mortality.

New research adds evidence on potential treatments targeting amyloid beta in Alzheimer's

New research could provide additional clues for future treatment targets to delay Alzheimer's disease and related dementias, according to the group's latest findings.

Highly sensitive and effective tool measures how your cells grow and divide

An improved sequencing tool reveals dynamic changes of poly(A) tails in eggs and embryos. By revealing the dynamic poly(A) regulation during the translation of RNA into protein, the study furthered our understanding as to how the fabric of life is shaped: from the color of your skin to your hair to how tall you will grow.

Scientists discover how certain proteins may help fight chlamydia

Scientists have made an interesting discovery, which may help fight chlamydia infection -- one of the most widespread STDs in the world. A series of experiments have shown that certain proteins are capable of killing harmful bacteria cells by shutting down their stress response system.

Conservation scientists help fish catch a break in Pohnpei

Underneath the waves of Palikir Pass, one of the world's top surf breaks in the Pacific Ocean, lies a new safe zone which aims to ensure the survival of local fisheries and the species that are caught in Pohnpei, Micronesia. It's all thanks to a group of scientists from Australia and Micronesia who have found by measuring how far fish travel, habitats can be better protected.

Beating the heat a challenge at the nanoscale

A little heat from a laser can disrupt measurements of materials at the nanoscale, according to scientists.

Prostate cancer breakthrough could lead to new diagnostic tests and treatments

Prostate cancer patients have been offered hope after scientists have identified a new group of molecules that could be targeted to slow tumor growth.

Eczema can have many effects on patients' health

When a patient is diagnosed with eczema, the diagnosis of another medical condition may not be far behind, say researchers. Eczema, also known as atopic dermatitis, is characterized by dry, red patches of skin accompanied by intense itchiness. Show More Summary

Creativity, intermedial languages as bridge to communicate with autistic children

This pioneering research using drama with autistic children started with an Arts and Humanities Research Council funded project 'Imagining Autism: Drama, Performance and Intermediality as Interventions for Autistic Spectrum Conditions' (2011-2014) working in special schools and has now extended to working with families

Microswimmer robot chains can decouple and reconnect in a magnetic field

Researchers have successfully pulled off a feat that both sci-fi fans and Michael Phelps could appreciate. Using a rotating magnetic field they show how multiple chains of microscopic magnetic bead-based robots can link up to reach impressive speeds swimming through in a microfluidic environment.

Recovery of dopamine function emerges with recovery from smoking

A new study reports that smoking-related deficits in brain dopamine, a chemical implicated in reward and addiction, return to normal three months after quitting. The normalization of dopamine systems suggests smoking-related deficits are a consequence of chronic smoking, rather than a risk factor. Show More Summary

Smartphone exercises for a better mood

Brief, directed smartphone exercises can help quickly improve our mood.

A sage discovery: Plant-derived compounds have potent anti-inflammatory effects

New research reveals that two specific plant-derived compounds may be effective for fighting inflammation and pain.

Videos reveal birds, bats and bugs near Ivanpah solar project power towers

Video surveillance is the most effective method for detecting animals flying around solar power towers, according to a study of various techniques by the U.S. Geological Survey and its partners at the Ivanpah Solar Electric Generating System facility in southeastern California. read more

New model may help solve the mystery of how lithium stabilizes moods

New measurements may have lifted the veil on the vexingly elusive interactions through which lithium can moderate the manic highs and debilitating lows experienced by people who suffer from bipolar disorder--about 2.6 percent of Americans, according to the National Institute of Mental Health. read more
