Very bizarre — cancer cells were modifying their metabolism based on communications they were receiving from cells in the microenvironment near the tumor.

Washington D.C., Mar 8 (ANI): A recent study has revealed that cancer cells get 30–60 percent of their fuel from eating their neighbours’ ‘words’.

Researcher Deepak Nagrath from Rice University said their original hypothesis was that cancer cells were modifying their metabolism based on communications they were receiving from cells in the microenvironment near the tumor, but none of them expected to find that they were converting the signals directly into energy.

Cells normally associated with protecting the brain from infection and injury also play an important role in rewiring the connections between nerve cells. And, constant generation of new pathways and networks among brain cells is critical in learning and keeping the mind sharp.

Possible new method in fighting cancer.

It is still a long ways off, but we just moved one step closer to a true cancer vaccine.

ACD Labs new solution is streamlining lab analysis.

ACD/Labs, a leading cheminformatics company, today announced it will introduce a set of new mixture analysis capabilities to its ACD/ChemAnalytical Workbook and ACD/Spectrus Platform. For more than a decade ACD/Labs’ software solutions have been used for analysis of complex chemical mixtures in a variety of industries including, but not limited to, pharmaceuticals, coatings, petroleum and lubricants, polymers, food and beverages, and environmental elements.„„ With the introduction of t…

At Camp Pendleton, Marines are testing a new, cutting edge form of live-fire training using robotic targets.

Stationary and on-rails targets are all well and good, but enemy combatants haven’t behaved like that since the formal battle lines of the Revolutionary War. It’s long past time for a training program that provides a more accurate simulation of today’s combat situations, and the Marines of Camp Pendleton are taking steps toward just that.

Solving the turbulence plasma mystery.

Cutting-edge simulations run at Lawrence Berkeley National Laboratory’s National Energy Research Scientific Computing Center (NERSC) over a two-year period are helping physicists better understand what influences the behavior of the plasma turbulence that is driven by the intense heating necessary to create fusion energy. This research has yielded exciting answers to long-standing questions about plasma heat loss that have previously stymied efforts to predict the performance of fusion reactors and could help pave the way for this alternative energy source.

The key to making fusion work is to maintain a sufficiently high temperature and density to enable the atoms in the reactor to overcome their mutual repulsion and bind to form helium. But one side effect of this process is turbulence, which can increase the rate of plasma heat loss, significantly limiting the resulting energy output. So researchers have been working to pinpoint both what causes the turbulence and how to control or possibly eliminate it.

Pretty cool.

Scientists report that amino acids, not sugar, supply most building blocks for cancerous tumor cells. Cancer cells are notorious for their ability to divide uncontrollably and generate hordes of new tumor cells. Most of the fuel consumed by these rapidly proliferating cells is glucose, a type of sugar.

Scientists had believed that most of the cell mass that makes up new cells, including cancer cells, comes from that glucose. However, MIT biologists have now found, to their surprise, that the largest source for new cell material is amino acids, which cells consume in much smaller quantities.

U.S. Defense Secretary Ash Carter said the National Guard’s cyber squadrons will play an increasingly important role in assessing the vulnerabilities of U.S. industrial infrastructure and could be asked to join the fight against Islamic State.

The National Guard – a reserve military force that resides in the states but can be mobilized for national needs – is a key part of the military’s larger effort to set up over 120 cyber squadrons to respond to cyber attacks and prevent them.

One such unit, the 262nd squadron, is a 101-person team that includes employees of Microsoft and Alphabet’s Google. The unit is “famous throughout the country” for several high profile vulnerability assessments, Carter said at the Joint Base Lewis-McChord in Tacoma, Washington late on Friday.
