Researchers Develop ‘Reversible’ Blood Thinner

The antibody specifically binds to coagulation factor Xla (FXla), which is a protein that has a vital role in the formation of blood clots. While this protein is seen as a major drug target, it has been difficult to specifically inhibit FXla. The new antibody does so, and blocks enzymatic activity.

For the new study, researchers, led by Tovo David showed that the drug was successful in preventing blood clots in blood of mice, rabbits and humans.

Electronic circuits printed at 1 micron resolution

A research team consisting of a group from National Institute for Materials Science (NIMS) International Center for Materials Nanoarchitectonics (MANA) and Colloidal Ink developed a printing technique for forming electronic circuits and thin-film transistors (TFTs) with line width and line spacing both being 1 μm. This study was supported by a Grant for Advanced Industrial Technology Development from NEDO.

Reducing runoff pollution by making spray droplets less bouncy

When farmers spray their fields with pesticides or other treatments, only 2 percent of the spray sticks to the plants. A significant portion of it typically bounces right off the plants, lands on the ground, and becomes part of the runoff that flows to streams and rivers — often causing serious pollution. But a team of MIT researchers aims to fix that.

By using a clever combination of two inexpensive additives to the spray, the researchers found they can drastically cut down on the amount of liquid that bounces off. The findings appear in the journal Nature Communications, in a paper by associate professor of mechanical engineering Kripa Varanasi, graduate student Maher Damak, research scientist Seyed Reza Mahmoudi, and former postdoc Md Nasim Hyder.

Not your typical protostar

Located over 12 000 light-years from us, this star has puzzled astronomers for many years because it shows conflicting signs of being both extremely old and extremely young.

Astronomers have spotted signs of emission usually associated with old, late-type stars: silicon oxide and hydroxyl masers – the microwave equivalent of a visible-light laser.

Mediterranean Diet Linked with Lower Risk of Death in Cardiovascular Disease Patients

The Mediterranean diet is associated with a reduced risk of death in patients with a history of cardiovascular disease, according to results from the observational Moli-sani study presented at ESC Congress 2016.

A visual nudge can disrupt recall of what things look like

Interfering with your vision makes it harder to describe what you know about the appearance of even common objects, according to researchers at the University of Wisconsin–Madison.

Development of Chemical Sensing Material that Enables Smartphones to Detect Toxic Gases

A joint research group including senior researcher Shinsuke Ishihara at the Frontier Molecules Group, International Center for Materials Nanoarchitectonics (MANA), National Institute for Materials Science (NIMS), and Professor Timothy M. Swager, at the Massachusetts Institute of Technology (MIT), developed a chemical sensing material whose electrical conductivity dramatically increases when exposed to toxic gases. In addition, the group integrated the sensing material into the electronic circuit in a near-field communication (NFC) tag, which is embedded in smart cards like those used to get through train ticket gates. Then, it was demonstrated that this technology made it possible for smartphones to quickly (in 5 sec) detect toxic gases at a low concentration (10 ppm).

Pushing through sand

For those of you who take sandcastle building very seriously, listen up: MIT engineers now say you can trust a very simple equation to calculate the force required to push a shovel — and any other “intruder”— through sand. The team also found that the same concept, known as the resistive force theory, can generate useful equations for cohesive materials like muds.

Continuous Roll-process Technology for Transferring and Packaging Flexible Large-scale Integrated Circuits

A research team in South Korea has developed a continuous roll-processing technology that transfers and packages flexible large-scale integrated circuits (LSI).
