A skull shows two wounds, almost identical, over the left brow, inflicted with the same implement, more than deep enough to kill. It is evidence of the oldest murder yet found on record, said scientists.
The genetic roots of autism have been investigated for more than a decade, as DNA sequencing has continued to improve. A new study points to a particular mutation in mice causing autistic-like behavior, adding to a list of potential causes.
FLIR Systems’ three new science-grade thermal cameras, the A6200sc NIR, A8300sc HD MWIR and A6700sc LWIR, are suited for demanding science and research applications including electronics development, university research and non-destructive testing.
Fisnar’s DC100 digital precision dispenser is highly programmable, boasting a high level of user control.
Drummond Scientific’s Programmable Nanoject III is the next generation in high precision microinjection.
The Asynt CondenSynis is a high-performance air condenser for synthetic chemistry experiments that requires no cooling water for operation.
The DS-1 benchtop incubator combines accurate temperature regulation per chamber and an equally accurate gas mixer.
Years, even decades, after remission some cancers return without warning. The “sleeping” cancer cells reactivate, “waking up” decades later, according to a British team of scientists, who say they may have found the molecular key to the change.
The Dionne Quintuplets, born May 28, 1934, were the first set of quintuplets to survive infancy. They were identical as they all came from one single egg and were born outside of Callander, Ontario, Canada. All five survived into adulthood.
Laboratory Equipment’s scientist of the week is Keith Clay, a professor from IU Bloomington. He and a team found that ticks are moving around the country and the diseases they carry are spreading with them.
A new algorithm can significantly reduce robot teams’ planning time. The plan the algorithm produces may not be perfectly efficient, but in many cases, the savings in planning time will more than offset the added execution time. Researchers tested the viability of the algorithm by using it to guide a crew of three robots in the assembly of a chair.
We may cave in to peer pressure, marketing and persuasion, but faced with decisions, the default response programmed into our brains is to say "no," a recent study suggests.
The first report from a public-private project to improve genetic testing shows it is not as rock solid as many people believe, with flaws that result in some people wrongly advised to worry about a disease risk and others wrongly told to relax. Researchers say the study shows the need for consumers to be careful about choosing where to have a gene test done and acting on the results, such as having or forgoing a preventive surgery.
Every year, an estimated half-million Americans undergo surgery to have a stent prop open a coronary artery narrowed by plaque. But sometimes the mesh tubes get clogged. A multi-tasking stent could minimize the risks associated with the procedure. It can sense blood flow and temperature, store and transmit the information for analysis and can be absorbed by the body after it finishes its job.
All of Japan's more than 40 nuclear reactors are currently offline for repairs or safety inspections. Today, a nuclear plant in southern Japan obtained the final permit needed to restart its reactors, paving the way for it to become the first to go back online under new safety standards introduced after the 2011 Fukushima disaster.
About 2.5 billion people worldwide don't have access to sanitary toilets. Latrines are an option for many of those people, but these facilities' overwhelming odors can deter users, who then defecate outdoors instead. To improve this situation, fragrance scientists paired experts' noses and analytical instruments to determine the odor profiles of latrines with the aim of countering the offensive stench.
