Changes in sex steroids associated with menopause

Research shows that the increased rate of follicle stimulating hormone (FSH) change that occurs during menopause is associated with increased objective sleep duration but poor subjective sleep quality.

Disease diagnosis in just 15 minutes

A team led by scientists at the University of Leeds has developed a biosensor technology that uses antibodies to detect biomarkers - molecules in the human body which are often a marker for disease – much faster than current testing methods.

Considering kidney-sparing surgery

A study of almost 1,500 kidney cancer patients suggests that surgery to spare as much kidney tissue as possible may improve overall survival in patients who also have reduced kidney function at the time their cancer is diagnosed.

Shade trees can protect coffee crops

Sustainable farming that employs shade trees may improve crops' resistance to temperature and precipitation extremes that climate changes are expected to trigger, according to a recently published article.

Rethinking receptor models

It may very well be that models used for the design of new drugs have to be regarded as impractical. This is the sobering though important conclusion of the work of two Leiden University scientists.

Coordinating the movement of cells

To get from their birthplace to their work site, cells sequentially attach to and detach from an elaborate track of exceptionally strong proteins known as the extracellular matrix.

Some bacteria fight infection

A new study shows that the DNA of so-called "good bacteria" that normally live in the intestines may help defend the body against infection.

Eel cells suggest electrifying possibilities

Researchers argue that artificial cells could be built that not only replicate the electrical behaviour of electric eel cells but in fact improve on them.

The properties of carbon nanotubes

A fresh discovery about the way water behaves inside carbon nanotubes could have implications in a wide variety of fields, including scientists' understanding of biological processes.

Impact of breast cancer test

Personal beliefs about inconclusive DNA testing for hereditary breast cancer are associated with cancer-related worry and predict whether women move on from the test.

Atlantic tuna return home

New research findings reported in Science have critical implications for how bluefin tuna are managed on both sides of the Atlantic Ocean.

Rethinking essential people in outbreak

Not only are doctors, nurses, and firefighters essential during a severe pandemic influenza outbreak. So, too, are truck drivers, communications personnel, and utility workers.

Scientists call for policy to guide biofuels

A group of scientists is calling for sustainable practises in an industry that will, as one says, "reshape the Earth's landscape in a significant way."

Predicting responses to fast-acting antidepressants

Images of the brain's fastest signals reveal an electromagnetic marker that predicts a patient's response to a fast-acting antidepressant, researchers have discovered.

New robotic repair system

Researchers at Queen's University are developing a new robotic system to service more than 8,000 satellites now orbiting the Earth, beyond the flight range of ground-based repair operations.

Thought processes made visible

An international team of scientists has succeeded in optically detecting individual action potentials in the brains of living animals.

Nanoscale polymers play by different rules

Scientists putting the squeeze on thin films of polystyrene have discovered that at very short length scales the polymer doesn't play by the rules.

Bypassing aluminium toxicity effects

Aluminium toxicity, a global agricultural problem, halts root growth in plants, severely limiting agricultural productivity for more than half of the world's arable land.

Bacterial crisis command centre

A bacteria cell's 'crisis command centre' has been observed for the first time swinging into action to protect the cell from external stress and danger, according to new research.

Key to rapid evolution in plants

Yale researchers have harnessed the power of 21st century computing to confirm an idea first proposed in 1916 - that plants with rapid reproductive cycles evolve faster.
