In the past few years, optical atomic clocks have made spectacular progress, becoming 100 times more precise than the best caesium clocks. So far, their precision has been available only locally, since frequency transfer...

Are lower levels of physical activity among African-American teens related to hair care? A new study has centralized itself around this very question.

Previous research has found that bisphenol S (BPS), a chemical used in the manufacture of plastic bottles and other products, is as harmful to the reproductive system as bisphenol A (BPA), which BPS replaced. Research su...

I often speak about the importance of experimentation. What about experimenting with how we govern ourselves? As we enter election season, I'm struck by the question, can we run meaningful experiments with government: ho...

Scientists have discovered the mechanism of the platelet programmed cell death, resulting in acceleration of the blood coagulation process by a factor of 1,000 to 10,000.

An evolutionary historian has determined that the region of origin of ancestors contributes to descendants' risk of developing certain medical conditions.

The Mediterranean diet can improve your mind, as well your heart, shows a new study.

Scientists have proposed a solution to the puzzle of how our immune system scales its response to any threat to our health to make it 'just right.' Their ideas could support a range of medical research. While T-cells usu...

An analysis of a nationally representative sample of US adults reveals that access to healthy foods in a supermarket does not hinder Americans' consumption of empty calories. In fact, the study found, US adults buy the b...

In a new study, researchers describe a new system that permits database queries for genome-wide association studies but reduces the chances of privacy compromises to almost zero.

Breast cancer tumors are complex and dynamic. They comprise a population of continuously dividing cells that carry different genetic mutations. New research reveals that treating human estrogen-receptor positive breast c...

The single-family room NICU increases maternal involvement, which results in better short and long-term neurobehavioral outcomes in preterm babies, new research suggests.

A new device could monitor blood clot formation and diagnose effectiveness of anti-platelet therapy by microengineering tiny hollow channels lined by chemically 'fixed' human endothelial cells that more closely mimic cel...

Patients with sickle cell anemia (SCA) develop heart complications and nearly a quarter die a sudden death. Now, researchers have linked malfunctioning molecular pathways to specific heart anomalies in SCA that result fr...

Researchers report that they have developed a new class of artificial proteins. In the long term, the results could lead to better treatment of cancer and diabetes.

Researchers have uncovered how genes identified from genome-wide association studies affect high-density lipoprotein cholesterol, a biomarker of cardiovascular disease, after comparing several animal models with human pa...

The overall prevalence of diabetic kidney disease has not changed significantly in the United States for 30 years, but the characteristics of kidney disease have changed markedly, according to a study.

Maintaining proper levels of an essential helper molecule is crucial for optimal muscle function. Some athletes are already taking supplements to increase synthesis of this compound, called NAD, with the hopes of reversi...

Clinical research often excludes females from their trials under the assumption that 'one size fits all,' that a painkiller or antidepressant will be equally effective in subjects of either sex, but a growing number of s...

Malignant cancers strike certain organs, such as the colon or breast, more often than others. Researchers propose that this vulnerability in some organs may be due to natural selection. Humans can tolerate tumors in larg...

Obesity was found to be more prevalent in patients with a history of cancer than in the general population, and survivors of colorectal and breast cancers were particularly affected. This study is among the first to comp...

Twenty percent of people hospitalized are released before all vital signs are stable, a pattern that is associated with an increased risk of death and hospital readmission, a new study shows.
