BioPORTER Protein Delivery Reagent from AMSBIO is a unique lipid formulation that allows direct translocation of proteins into living cells. It is the first and only lipid-based protein delivery system that efficiently transports proteins into living cells.
From far away, the top of a leaf looks like one seamless surface; however, up close, that smooth exterior is actually made up of a patchwork of cells in a variety of shapes and sizes. Interested in how these cells individually take on their own unique forms, a team sought to pinpoint the shape-controlling factors in pavement cells, which are puzzle-piece-shaped epithelial cells found on the leaves of flowering plants.

In the field of neuromorphic engineering, researchers study computing techniques that could someday mimic human cognition. Electrical engineers at the Georgia Institute of Technology recently published a "roadmap" that details innovative analog-based techniques that could make it possible to build a practical neuromorphic computer.
A research group in Japan has developed a new advanced system that combines a super-resolution microscope and a deposition chamber for growing oxide thin films. With this system, they successfully observed for the first time the growing of metal-oxide thin films at an atomic level on the surface of single-crystal strontium titanate.
Although it is relatively cheap and easy to encode information in light for fiber optic transmission, storing information is most efficiently done using magnetism, which ensures information will survive for years without any additional power. But a new proposal by researchers would replace silicon used in these devices with plastic. Their solution converts magnetic information to light in a flexible plastic device.
Researchers in Pennsylvania and Texas have shown the ability to grow high quality, single-layer materials one on top of the other using chemical vapor deposition. This highly scalable technique, often used in the semiconductor industry, can produce materials with unique properties that could be applied to solar cells, ultracapacitors for energy storage, or advanced transistors for energy efficient electronics, among many other applications.
A novel antiviral drug may protect people infected with the measles from getting sick and prevent them from spreading the virus to others, an international team of researchers says. The team of researchers developed the drug and tested it in animals infected with a virus closely related to one that causes the measles. As reported, virus levels were significantly reduced when infected animals received the drug by mouth.
Scientists at Yale Univ. have confirmed a 50-year-old, previously untested theoretical prediction in physics and improved the energy storage time of a quantum switch by several orders of magnitude. High-quality quantum switches are essential for the development of quantum computers and the quantum Internet.
These days, Hugh Herr, an assoc. prof. of media arts and sciences at Massachusetts Institute of Technology, gets about 100 emails daily from people across the world interested in his bionic limbs. Messages pour in from amputees seeking prostheses and from media outlets pursuing interviews. Then there are students looking to join Herr’s research group.
In the midst of the diabetes epidemic, a glimmer of good news: Heart attacks, strokes and other complications from the disease are plummeting. Over the last two decades, the rates of heart attacks and strokes among diabetics fell by more than 60%, a new federal study shows. The research also confirms earlier reports of drastic declines in diabetes-related kidney failure and amputations.
Carefully timed pairs of laser pulses at the Linac Coherent Light Source have been used to trigger superconductivity in a promising copper-oxide material and immediately take x-ray snapshots of its atomic and electronic structure as superconductivity emerged. The results of this effort have pinned down a major factor behind the appearance of superconductivity, and it hinges around “stripes” of increase electrical charge.
AdvantaPure now offers its stainless steel overbraided PTFE hose in four styles. The hose, called APFOS, provides the purity of PTFE fluoropolymer with the durability and enhanced pressure carrying capabilities of stainless steel.
A new peristaltic pump enables researchers working in bioprocessing environments to achieve the precision and reliability needed to improve their processes. The Thermo Scientific Miniflex peristaltic pump delivers an expanded flow range of up to 370 mL per minute, allowing researchers to effectively dispense low- and high-volume fluids with repeatability and accuracy on a scale previously not offered by pumps of equivalent size.
It seems there are new caffeine-infused products hitting the shelves every day. From energy drinks to gum and even jerky, our love affair with this little molecule shows no signs of slowing. In a recent American Chemical Society video, the science behind the world’s most popular drug is explained, including why it keeps you awake and how much caffeine is too much.
