#Decoding sugar addiction Together, obesity and Type 2 diabetes rank among our nation greatest health problem,
and they largely result from what many call an ddictionto sugar. But solving this problem is complicated more than solving drug addiction,
because it requires reducing the drive to eat unhealthy foods without affecting the desire to eat healthy foods when hungry.

we have identified how the brain encodes compulsive sugar seeking and wee also shown that it appears to be distinct from normal,
adaptive eating, says senior author Kay Tye, a principle investigator at the Picower Institute for Learning and Memory who previously developed novel techniques for studying brain circuitry in addiction
noninvasive approaches to avert maladaptive eating behaviors, first in mice and eventually in people. Drug addiction is defined as compulsive drug-seeking despite adverse consequences at school
But food is a natural reward and, unlike a drug, is necessary for survival, so it has been unclear
that compulsive sugar consumption is mediated by a different neural circuit than physiological, healthy eating. For the study, Tye and her graduate student Edward Nieh focused on the connections between the VTA and the lateral hypothalamus (LH),
Mice naturally love sucrose similar to humans loving sugar-rich sodas so Nieh trained mice to seek out sucrose at a delivery port upon hearing
Activating the projections led to compulsive sucrose-eating and increased overeating in mice that were full.

Coffee, apple juice, and Vitamin c: things that people ingest every day are experimental material for chemist Eva-Maria Felix.
"She preferred not to use cyanide, formaldehyde, arsenic and heavy metal salts. She was inspired by a journal article by researchers who achieved silver precipitation using coffee.
Felix also used coffee in her first experiments. She then tested apple juice, followed by Vitamin c.
This seemed to be suited the best to her because"you never know what's in coffee and apple juice."
"On the other hand, Vitamin c-or ascorbic acid-is available in pure form from chemical stores-a requirement for reproducible studies.
But what does the vitamin have to do with the precipitation of gold? In the human body, Vitamin c makes free radicals harmless by transferring electrons to them."

Making the solid-state device is just like making a sandwich just with ultra high-tech semiconductor tools used to slice
and stack the atomic-sized layers of meats and cheeses like the butcher shop's block.
First they made a sandwich composed of two metal electrodes separated by a two-nanometer thick insulating layer (a single nanometer is 10000 times smaller than a human hair) made by using a semiconductor technology called atomic layer deposition.
Then a hole is cut through the sandwich: DNA bases inside the hole are read as they pass the gap between the metal layers.
However the U s. Food and Drug Administration has approved now the use of iron-oxide nanoparticles in humans.

#Researchers develop green tea-based'missiles'to kill cancer cells more effectively Green tea has long been known for its antioxidant, anticancer, antiaging and antimicrobial properties.
A group of researchers from the Institute of Bioengineering and Nanotechnology (IBN) of A*STAR has taken the health benefits of green tea to the next level by using one of its ingredients to develop a drug delivery system
A key ingredient in green tea, epigallocatechin gallate (EGCG), is an antioxidant which is known to have therapeutic applications in the treatment of many disorders including cancer.
The numerous health benefits of green tea have inspired us to utilize it in drug delivery systems.
This is the first time that green tea has been used as a material to encapsulate and deliver drugs to cancer cells.
Our green tea nanocarrier not only delivered protein drugs more effectively to the cancer cells, the combination of carrier and drug also dramatically reduced tumor growth compared with the drug alone.
The research team conducted animal studies to evaluate the performance of IBN's green tea-based protein delivery system.
The study revealed that IBN's green tea nanocomplex loaded with Herceptin reduced tumor growth much more effectively
We have developed a green tea-based carrier in which the carrier itself displayed anticancer effect and can boost cancer treatment when used together with the protein drug.
Unlike conventional therapy our green tea carrier can eradicate more cancer cells and accumulate significantly less drugs in vital organs where they could cause adverse side effects.
IBN has filed a patent on their green tea nanocarrier and is developing this technology for clinical applications.
The green tea-based micellar complexes are also being examined for the delivery of active ingredients in personal care and nutritional products s
The ions ejected by Velsquez-Garca's prototype are produced from an ionic salt that's liquid at room temperature.

#Aligned carbon nanotube/graphene sandwiches By in situ nitrogen doping and structural hybridization of carbon nanotubes (CNTS) and graphene via a two-step chemical vapor deposition (CVD) scientists have fabricated nitrogen-doped aligned carbon nanotube/graphene (N-ACNT/G) sandwiches
with three-dimensional (3d) electron transfer pathways interconnected ion diffusion channels and enhanced interfacial affinity and activity.
The as-fabricated N-ACNT/G sandwiches described in the journal Advanced Materials on Sep 17 2014 demonstrated high-rate performances in lithium-sulfur (Li-S) batteries.
After catalyst removal alternative aligned CNTS and graphene were connected vertically to each other in long-range periodicity thereby forming a sandwich-like structure.
The remarkable cycling capacity and rate capability can be attributed to the novel structural and chemical characteristics of the N-ACNT/G sandwiches Prof.
It is expected highly that the N-ACNT/G sandwiches hold various potential applications in the area of nanocomposite energy storage environmental protection electronic device as well as healthcare because of their robust hierarchical structure 3d electron transfer

#Watch A 3-D Printer Make A Pizza#This summer we heard about a 3-D printer for food developed with NASA funding
The printer#served up a pie made with dough#ketchup and cream cheese(?.The printer is still in its earliest stages so the creators haven't quite perfected the process.
Instead of making a classic slice they're showing off the proper levels of pizza viscosity with similar ingredients:
ketchup for sauce cream cheese for a fine ricotta. The idea's more or less the same though:
the printer lays down a layer of dough from a stock of simple non-perishable ingredients then layers the sauce (ketchup) and cheese (cream cheese) on top.
A heated surface bakes the pizza.##You can see why NASA would be interested in the idea:
send up a printer instead of boxes of food and you save space plus you give the astronauts a home-cooked meal.

"what happens inside a cow's stomach after dinner, "as this Ohio State university presentation puts it.
The food goes into oxygen-free tanks with particular bacteria species inside that thrive without oxygen.
Those bacteria break down the food in many steps; during the last step, bacteria produce primarily carbon dioxide and methane gas.
Anaerobic digestion is considered also a less favored way of dealing with excess food. From an environmental standpoint, it's better to chop food up into deli salad,
give it away to charities, or send it to animal feed. But if there's some food you can't avoid throwing away,

#Tofu handling robot picks up soft, delicate food with ease Lands Work a manufacturer of tofu-making machinery has developed a robot that can pick up very soft foods such as tofu
which way the tofu is facing and how big it is using a camera. The images are analyzed by a computer and the robot works out
which way to orient the tofu. Once it picks the tofu up it then puts it in a package.
A feature of this robot is the hand which can gently carry very soft fragile things without damaging them.
If tofu is carried quickly it breaks. So the robot moves tofu quite slowly shifting only 1200 to 1500 pieces per hour.
But firmer items such as fried tofu can be carried at a rate of 2500 per hour.?
We are using mainly firm tofu in our demonstration but it can also handle soft tofu.
Wee also included some soft tofu here so this system can even handle delicate things like that.?
Wee only just developed this system. People have asked about using it for seafood eggs and meat and we think it could be used for all kinds of foods.
The robot itself is a very general-purpose model. So for example if we reduce production volume on one line we could use the robot on another line just by changing its program.
That the best thing about using robots. n
