Scholars from Rice University, University College London and the Field Museum have found the first direct evidence that glass was produced in sub-Saharan Africa centuries before the arrival of Europeans, a finding that the researchers said represents a 'new chapter in the history of glass technology.'
Northwestern University researchers have developed a first-of-its-kind technique for creating entirely new classes of optical materials and devices that could lead to light bending and cloaking devices -- news to make the ears of Star Trek's Spock perk up. Using DNA as a key tool, the scientists took gold nanoparticles of different sizes and shapes and arranged them in two and three dimensions to form optically active superlattices. The structures could be programmed to exhibit almost any color across the visible spectrum.
A study published in the Journal of the National Cancer Institute indicates that screening the general population for mutations in specific genes is a more cost effective way to detect people at risk and prevents more breast and ovarian cancers compared to only screening patients with a personal or family history of these diseases.
Data collected during a long-term health study provides additional evidence for a link between increased risk of cancer in individuals with advanced gum disease, according to a new collaborative study led by researchers at the Johns Hopkins Bloomberg School of Public Health, Johns Hopkins Kimmel Cancer Center and Tufts University School of Medicine and Cancer Center.
Researchers at the University of Sheffield and Boston's Children Hospital, Harvard Medical School have created a robot that can be implanted into the body to aid the treatment of oesophageal atresia, a rare birth defect that affects a baby's oesophagus.
Johns Hopkins Kimmel Cancer Center researchers developed a single blood test that screens for eight common cancer types and helps identify the location of the cancer.
As co-author of a study published in Global Change Biology, Kenneth Feeley, along with fellow biologist, Richard Tito, a native Quechua Indian from the region and the study's first author, discovered that tough times lie ahead for rural farmers growing the Andes' staple crops -- corn and potatoes.
Atomic-resolution transmission electron microscopy of electron beam-sensitive crystalline materials.
Georgia Techhas developed a new way of mining data from climate data sets that is more self-contained than traditional tools. The methodology brings out commonalities of data sets without as much expertise from the user, allowing scientists to trust the data and get more robust -- and transparent -- results.
An international review led by the University of Queensland and WCS (Wildlife Conservation Society) says that many native carnivores that live in and around human habitation are declining at an unprecedented rate - spelling bad news for humans who indirectly rely on them for a variety of beneficial services.
Geneticists have solved a century-old mystery by discovering a remarkable mechanism that enables plants to count their chromosomes. Their ability to detect imbalances in male and female contributions to the next generation determines their progeny's viability and fertility.
A new study details the minute changes -- down to the level of individual atoms -- that cause a particular protein to form cell-damaging clumps associated with ALS and other diseases.
Babies are adept at getting what they need -- including an education. New research shows that babies organize mothers' verbal responses, which promotes more effective language instruction, and infant babbling is the key.
A new Michigan State University study is helping to answer a pressing question among scientists of just how close mice are to people when it comes to researching cancer. The findings reveal how mice can actually mimic human breast cancer tissue and its genes, even more so than previously thought, as well as other cancers including lung, oral and esophagus.
Scientists have solved a longstanding puzzle of how cells are able to tightly package lengthy strands of DNA when they divide -- an essential process for growth, repair and maintenance in living organisms.
In cooperation with Universidad Rey Juan Carlos - URJCAn international team of researchers, including ERC grantee Fernando T. Maestre from Universidad Rey Juan Carlos (URJC), pieced together a global atlas of soil bacteria. The study, published today in Science, identifies some five hundred species of dominant bacteria living in soils worldwide. The findings, based on EU-funded research, could open new paths to improve soil fertility and increase agricultural production.
A new study led by Danielle Bassett at The University of Pennsylvania's School of Engineering and Applied Science is the first to convert the entire human body's network of bones and muscles into a comprehensive mathematical model. A study of the network is publishing on Jan. 18 in the open-access journal PLOS Biology.
More than 700,000 Americans were hospitalized due to illnesses associated with the seasonal flu during the 2014-15 flu season, according to federal estimates. A radical new approach to vaccine development at UCLA may help lower that figure for future flu seasons.
The volume of hydraulic fracturing fluid and the location of well pads control the frequency and occurrence of measurable earthquakes, new Alberta Geological Survey and UAlberta research has found.
By powering a DNA nanorobotic arm with electric fields, scientists have achieved precise nano-scale movement that is at least five orders of magnitude faster than previously reported for DNA-driven robotic systems.
