Quantitative three-dimensional analysis of bone wear patterns can provide insight into the manufacture and use of early human tools, according to a new study.

A new staging system developed with a more accessible test to predict the chance of survival in patients living with light chain (AL) amyloidosis.

By creating a machine-learning algorithm that predicts how human and mouse cells respond to CRISPR-induced breaks in DNA, a team of researchers discovered that cells often repair broken genes in ways that are precise and...

A very small molecule under study is able to kill a childhood brain cancer, and the lead researcher said it may be possible to reduce by 90 percent the amount of chemotherapy and radiation required to kill such tumors.

Patients hospitalized with a cardiovascular event are more likely to die within one year if they have low health literacy, according to a new study.

When Chlamydia trachomatis, the bacterium that causes one of the most common sexually transmitted infections worldwide, enters a human cell, it hijacks parts of the host to build protective layers around itself. Inside t...

The first large study of surgical opioid prescribing and patient usage shows the potential for reduced amounts and the importance of safe disposal of unused pills.

A new study shows how cyanobacteria, or bacteria that produce energy through photosynthesis like plants, change the way they grow and divide in response to different levels of light.

Wormholes are usually illustrated as gaping gravity wells linked by a narrow tunnel, but their precise shape has been unknown -- until now.

Lover of the light MOST SPIDERS avoid light because, besides being predators, they are also potential prey. But there is a set of circumstances in which living beside a powerful light is an advantage. This is when you ar...

WELL BEGUN, half done. That proverb, ascribed to Aristotle, seems an apt description of the art market--at least it is if a study of artistic careers, published this week in Science, is to be believed. In this study Albe...

Laser-based 'optical tweezers' could levitate uranium and plutonium particles, thus allowing the measurement of nuclear recoil during radioactive decay. This technique, proposed by scientists at Los Alamos National Labor...

Beatboxing is a musical art form in which performers use their vocal tract to create percussive sounds. Sometimes individual beatboxers perform as a part of an ensemble, using their vocal tracts to provide beats for othe...

A system proposed by world war two codebreaker Alan Turing more than 60 years ago can explain the patterning of tooth-like scales possessed by sharks, according to new research.

A blood test can detect if you have breast, bowel or other cancers by looking for characteristic tumour DNA fragments that have leaked into the circulation

Despite its role in shaping life as we know it, many aspects of photosynthesis remain a mystery. An international collaboration between scientists at SLAC National Accelerator Laboratory, Lawrence Berkeley National Labor...
