Glad to be home

A study by UC Santa Barbara anthropologists found that Tsimane men's oxytocin levels increase when they come home to their families after a day of hunting, positively correlating with changes in testosterone. This hormonal response may serve as a balance between social bonding and competition.

Finding support for surgery on Facebook

A recent study by Dartmouth researchers found that Facebook conversations about surgery reveal a common pattern of call-and-response in asking for and offering prayers. Nearly four thousand people posted about surgery, with posts referencing family members triggering greater responses via comments.

An improved method for coating gold nanorods

Gold nanorods are being investigated for use in biomedical applications due to their surface plasmon resonance, allowing them to absorb and scatter light. The improved method enables large-scale production and controlled shell thicknesses, paving the way for stable gold nanorods with chemically functionalized surfaces.

Is too much artificial light at night making us sick?

Research suggests that too much artificial light in the evening can disrupt the body's circadian rhythm and lead to health problems such as breast cancer, obesity, diabetes, and depression. Experts recommend using devices with dimmer, longer wavelengths of light in the evening to minimize disruption.

Study sheds new light on asthma, COPD

A new study from Washington University School of Medicine has linked a protein called CLCA1 to the overproduction of mucus in diseases like asthma and COPD. Increased expression of CLCA1 increases the number of TMEM16A channels present in nearby cells, leading to more Ca2+ dependent chloride currents.

Evolution of the back-to-belly axis

Researchers found that sea anemones use BMP signaling molecules to establish a second body axis, regulating mesenteries and Hox gene activation. This discovery provides insights into the evolution of animal body axes over hundreds of millions of years.

Moral decisions can be influenced by eye tracking

A study by Lund University researchers found that people's moral responses can be influenced by what they're looking at when making a decision. The findings suggest that the thought process needed to reach a moral position is interlinked with the process of viewing the world.

How planthoppers got their wings

Brown planthoppers develop short wings for breeding and long wings for travel due to insulin receptor silencing, a major factor in their pest status. Researchers found that two insulin receptors determine alternative wing morphs in planthoppers.

Finding out what's in 'fracking' wastewater

A recent spill of 3 million gallons of fracking wastewater in North Dakota has raised concerns about the potential harm it could cause to human health and the environment. Scientists are using advanced analytical techniques to study the composition of fracking fluids and wastewater, which may break down differently in the environment.

Study may explain low blood oxygen for cystic fibrosis patients with infected lungs

Researchers discovered a new bodily process that explains low blood oxygen in cystic fibrosis patients with infected lungs, highlighting the importance of CFTR protein function in directing blood flow. The study suggests strategies aimed at restoring or activating the CFTR protein may improve blood oxygen levels and circulation.

Why people with diabetes can't buy generic insulin

A Johns Hopkins study reveals that drug companies have extended patents on insulin for over 90 years, preventing generic versions from entering the market. This has led to costly treatment options, with prices ranging from $120 to $400 per month, and hospitalizations due to uncontrolled diabetes.

Submarine groundwater discharge adds as much nutrients as rivers to the Mediterranean Sea

A new study calculates the magnitude of submarine groundwater discharge into the Mediterranean Sea, revealing it can add as much nutrients as rivers. The annual volume of SGD ranges from 30 to 500 billion cubic meters, with a median nutrient flux comparable to atmospheric deposition and riverine runoff.

Insuring undocumented residents could help solve multiple US health care challenges

A UCLA study identifies four key problem areas for Latinos under the Affordable Care Act: uninsurance of undocumented residents, growing Latino population in non-expansion states, increased demand on health systems, and language barriers. Insuring undocumented residents could improve access to care and reduce costs.

Location, location, location: Bike-sharing systems need revamp to attract more riders

A new study by University of Chicago Booth School of Business researchers found that redesigning bike networks can increase ridership by up to 29.4% and reduce the distance commuters need to walk to reach stations. By taking commuter preferences into account, cities can optimize their bike-share systems to attract more users.
