BUFFALO, N.Y. -- A thin film that reflects light in intriguing ways could be used to make road signs that shine brightly and change color at night, according to a study that will be published on Aug. 9 in Science Advances.

The technology could help call attention to important traffic information when it's dark, with potential benefits for both drivers and pedestrians, researchers say.

The film consists of polymer microspheres laid down on the sticky side of a transparent tape.

The material's physical structure leads to an interesting phenomenon: When white light shines on the film at night, some observers will see a single, stable color reflected back, while others will see changing colors.

It all depends on the angle of observation and whether the light source is moving.

The research was led by Limin Wu, PhD, at Fudan University in China, whose group developed the material.

CHAMPAIGN, Ill. -- Researchers have found a way to use polymer printing to stretch and flatten twisted molecules so that they conduct electricity better.

The conjunction allows electricity to travel very quickly through a polymer, making it highly desirable for use in electrical and optical applications.

This mode of transporting charges works so well that conjugated polymers are now poised to compete with silicon materials, the researchers said.

However, these polymers tend to contort into twisted spirals when they join, severely impeding charge transport.

"Even a slight twist of the backbone can substantially hinder the ability of the electrons to delocalize and flow."

It is possible to flatten conjugated polymers by applying an enormous amount of pressure or by manipulating their molecular structure, but both techniques are very labor-intensive, Diao said.

Machine learning, introduced 70 years ago, is based on evidence of the dynamics of learning in our brain.

Using the speed of modern computers and large data sets, deep learning algorithms have recently produced results comparable to those of human experts in various applicable fields, but with different characteristics that are distant from current knowledge of learning in neuroscience.

Using advanced experiments on neuronal cultures and large scale simulations, a group of scientists at Bar-Ilan University in Israel has demonstrated a new type of ultrafast artifical intelligence algorithms -- based on the very slow brain dynamics -- which outperform learning rates achieved to date by state-of-the-art learning algorithms.

In an article published today in the journal Scientific Reports, the researchers rebuild the bridge between neuroscience and advanced artificial intelligence algorithms that has been left virtually useless for almost 70 years.

"The current scientific and technological viewpoint is that neurobiology and machine learning are two distinct disciplines that advanced independently," said the study's lead author, Prof. Ido Kanter, of Bar-Ilan University's Department of Physics and Gonda (Goldschmied) Multidisciplinary Brain Research Center.

"The number of neurons in a brain is less than the number of bits in a typical disc size of modern personal computers, and the computational speed of the brain is like the second hand on a clock, even slower than the first computer invented over 70 years ago," he continued.

EVANSTON, Ill. -- Targeted drug-delivery systems hold significant promise for treating cancer effectively by sparing healthy surrounding tissues.

A Northwestern University research team has developed a new way to determine whether or not single drug-delivery nanoparticles will successfully hit their intended targets -- by simply analyzing each nanoparticle's distinct movements in real time.

By studying drug-loaded gold nanostars on cancer cell membranes, the researchers found that nanostars designed to target cancer biomarkers transited over larger areas and rotated much faster than their non-targeting counterparts.

"Moving forward, this information can be used to compare how different nanoparticle characteristics -- such as particle size, shape and surface chemistry -- can improve the design of nanoparticles as targeting, drug-delivery agents," said Northwestern's Teri Odom, who led the study.

The study published today (Aug. 9) in the journal ACS Nano.

Odom is the Charles E. and Emma H. Morrison Professor of Chemistry in Northwestern's Weinberg College of Arts and Sciences.

Generally speaking, most people find the idea of workers being replaced by robots or software worse than if the jobs are taken over by other workers.

But when their own jobs are at stake, people would rather prefer to be replaced by robots than by another employee.

Over the coming decades, millions of jobs will be threatened by robotics and artificial intelligence.

Despite intensive academic debate on these developments, there has been little study on how workers react to being replaced through technology.

Their findings have now been published in the renowned journal Nature Human Behaviour.

Human replacements pose greater threat to feeling of self-worth

How do a small group of cells organize to become a heart, a brain, or a kidney?

This critical period of development has long remained the black box of developmental biology, in part because no sensor was small or flexible enough to observe this process without damaging the cells.

Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have grown simplified organs known as organoids with fully integrated sensors.

These so-called cyborg organoids offer a rare glimpse into the early stages of organ development.

I think if we can develop nanoelectronics that are so flexible, stretchable, and soft that they can grow together with developing tissue through their natural development process, the embedded sensors can measure the entire activity of this developmental process," said Jia Liu, Assistant Professor of Bioengineering at SEAS and senior author of the study.

"The end result is a piece of tissue with a nanoscale device completely distributed and integrated across the entire three-dimensional volume of the tissue."

Typhoon Krosa is a large storm moving through the Northwestern Pacific Ocean and infrared imagery from NASA's Aqua satellite revealed that the large typhoon also has a large eye.

Cloud top temperatures provide information to forecasters about where the strongest storms are located within a tropical cyclone.

NASA's Aqua satellite took Typhoon Krosa's cloud top temperatures to get that information.

NASA's Aqua satellite analyzed the storm on Aug. 7 at 11 p.m. EDT (0359 UTC) using the Atmospheric Infrared Sounder or AIRS instrument.

The stronger the storms, the higher they extend into the troposphere, and they have the colder cloud temperatures.

AIRS found coldest cloud top temperatures as cold as or colder than minus 63 degrees Fahrenheit (minus 53 degrees Celsius) around the eye and in large bands south and east of the center.

HANOVER, N.H. - August 9, 2019 - Certain strains of cholera can change their shape in response to environmental conditions to aid their short-term survival, according to new research from Dartmouth College.

In the research, some strains of the bacterium Vibrio cholerae transformed themselves from small, comma-shaped cells to long filaments in nutrient-poor environments.

According to the study, the formation of the elongated cell shapes allows the rapid formation of communities of bacteria that bind to surfaces - known as biofilms - that are essential in turbulent nutrient environments.

"Bacteria are normally thought of as solitary organisms, but they are actually highly-social organisms that like to live in groups," said Carey Nadell, an assistant professor of biology at Dartmouth.

"This research shows that we can relate cell structure to group behavior in new ways when looking at realistic environments."

When not inside a human host, V. cholerae grows on nutritious pieces of debris in aquatic environments.

A technology that can obtain high-resolution, micrometer-sized images for mass spectrometric analysis without sample preparation has been developed.

DGIST Research Fellow Jae Young Kim and Chair-professor Dae Won Moon's team succeeded in developing the precise analysis and micrometer-sized imaging of bio samples using a small and inexpensive laser.

DGIST announced that Research Fellow Jae Young Kim in the Department of Robotics Engineering and Chair-professor Dae Won Moon's team developed a technology that can analyze experiment samples without any preparation processing.

Due to its ability to obtain high-resolution mass spectrometric images without an experimental environment using 'continuous wave laser'1, the technology is expected to be applied widely in the precise medicine and medical diagnosis fields.

Many advance preparations are needed for the mass spectrometric imaging of biometric samples using 'specimen,' which thinly cut an object to analyze.

The specimen must be changed artificially since they cannot be analyzed accurately in a room temperature or atmospheric pressure.

Stem cells hold the key to wound healing, as they develop into specialised cell types throughout the body - including in teeth.

Published today (Friday 9 August) in Nature Communications, the study showed that a gene called Dlk1 enhances stem cell activation and tissue regeneration in tooth healing.

Importantly, the work showed that when these stem cells are activated, they then send signals back to the mother cells of the tissue to control the number of cells produced, through a molecular gene called Dlk1.

This paper is the first to show that Dlk1 is vital for this process to work.

This mechanism could provide a novel solution for tooth reparation, dealing with problems such as tooth decay and crumbling (known as caries) and trauma treatment.

Further studies need to take place to validate the findings for clinical applications, in order to ascertain the appropriate treatment duration and dose, but these early steps in an animal model are exciting, as Dr Hu explains.

Technology that can help interpret inaudible calls from laboratory mice has been developed in a bid to improve research.

The computer tool can reveal valuable insights into rodents' communication patterns and is more reliable than existing methods, which rely on human interpretation.

The system analyses audio recordings of ultrasonic vocalisations - beyond the range of human hearing.

Researchers say it could support research involving mice, which play a crucial role in testing new therapies for human diseases.

Monitoring rodent communications can reveal important information about how diseases progress, particularly for neurological disorders such as Parkinson's disease and autism.

Experts previously categorised mouse communications into nine call types by manually deciphering visual representations of the soundwaves, known as spectrograms.

The main risks to bees include wide-spread pesticide use in agriculture, parasites, disease and climate change, and crucially - the loss of valuable biodiversity which poses a further threat to bees and other wild pollinators.

One way to help boost their numbers is by planting the correct wildflowers, providing a better habitat for pollinators to disperse, nest and breed.

However, it is unclear which plant species are the most preferred between different pollinators, including bees, and how this might change over time and in different environmental conditions.

Historically, scientists used light microscopy to identify individual bee-collected pollen grains, which was a time-consuming and impractical method.

To obtain a more accurate understanding without the need for laborious manual inspection of pollen, scientists have developed a rapid analysis method called 'Reverse Metagenomics' (RevMet) that can identify the plants that individual bees visit using the MinION, a portable DNA sequencer from Oxford Nanopore Technologies.

The portability of the equipment involved means that this type of analysis could be performed on-site where bees are collected and sampled - vastly increasing our understanding of where bees look for pollen on a national scale.

NOAA-NASA's Suomi NPP satellite captured this image using NASA's Earth Observing System Data and Information System (EOSDIS) Worldview application on Aug. 08, 2019 and it shows Supertyphoon Lekima heading towards the coast of China as Typhoon Krosa brings up the rear moving slowly towards Japan.

Typhoon Krosa is currently located 167 nautical miles southwest of Iwo To, Japan.

It is slowly tracking northeastward at one knot over the past six hours making it quasi-stationary as it intensified and maintained its 14 nautical mile eye.

Krosa's winds are steady at approximately 100 knots (115 mph) which on the Saffir-Simpson hurricane scale would make this storm just over the Category 3 designation.

Like Lekima, Krosa is able to intensify due to low vertical wind shear and warm sea surface temperatures in the area of 30 degrees C (86 degrees F) both of which are favorable to typhoon development and intensification.

For the time being, Krosa will remain quasi-stationary and continue to intensify for the next 12 hours.

NASA's Aqua satellite captured this infrared image of Supertyphoon Lekima as it tracked 214 nautical miles southwest of Okinawa, Japan.

Tropical cyclone warning signal 1 is in force for the Luzon provinces of Batanes and Babuyan group of islands.

The storm has tracked north-northwest at 10 knots over the past six hours.

Satellite imagery shows this system continues to rapidly intensify as evidenced by tightly compact central convection which includes an eight nautical mile-sized eye with a tight pinhole in the eye which is an indication of a strong storm.

The supertyphoon is currently producing winds in excess of 130 knots (149 mph).

On the Saffir-Simpson hurricane scale that would be a Category 4 hurricane.

Cybersecurity researchers at Tel Aviv University and the Technion Institute of Technology have discovered critical vulnerabilities in the Siemens S7 Simatic programmable logic controller (PLC), one of the world's most secure PLCs that are used to run industrial processes.

Prof. Avishai Wool and M.Sc student Uriel Malin of TAU's School of Electrical Engineering worked together with Prof. Eli Biham and Dr. Sara Bitan of the Technion to disrupt the PLC's functions and gain control of its operations.

The team is slated to present their findings at Black Hat USA week in Las Vegas this month, revealing the security weaknesses they found in the newest generation of the Siemens systems and how they reverse-engineered the proprietary cryptographic protocol in the S7.

"The station was able to remotely start and stop the PLC via the commandeered Siemens communications architecture, potentially wreaking havoc on an industrial process," Prof.

"We were then able to wrest the controls from the TIA and surreptitiously download rogue command logic to the S7-1500 PLC."

The researchers hid the rogue code so that a process engineer could not see it.

COLUMBUS, Ohio - In 1919, America had a problem with dynamite.

Several people were killed and more were injured.

The Contested Role of History in Contemporary Debates on the Second Amendment.

In the wake of the mass shootings in El Paso and Dayton this week, Roth said his research suggests that the government needs to regulate the most deadly guns and make it harder for the public to buy them - just as it did with dynamite.

But what is different now is the lethal power of guns and the ease with which large-capacity semiautomatic rifles can be modified to fire extremely quickly.

What is different now is that a single individual can have enough lethal power to kill scores of people.

A team of environmental scientists from the University of Massachusetts Amherst and China has for the first time used a dynamic, two-step process to completely degrade a common flame-retardant chemical, rendering the persistent global pollutant nontoxic.

This new process breaks down tetrabromobisohenol A (TBBPA) to harmless carbon dioxide and water.

The discovery highlights the potential of using a special material, sulfidated nanoscale zerovalent iron (S-nZVI), in water treatment systems and in the natural environment to break down not only TBBPA but other organic refractory compounds that are difficult to degrade, says Jun Wu, a visiting Ph.D. student at UMass Amherst's Stockbridge College of Agriculture and lead author of the paper published in Environmental Science & Technology.

"This is the first research about this dynamic, oxic/anoxic process," Wu says.

"Usually, reduction or oxidation alone is used to remove TBBPA, facilitated by S-nZVI.

Wu emphasizes that "the technique is technically simple and environmentally friendly.

An international collaboration of researchers from the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan and Gladstone Institutes in the USA have generated 3D blastocyst-like structures from stem cells.

After many more cell divisions, the embryo turns into a blastocyst that is implanted in the womb where it differentiates and grows into a fetus.

Inside are pluripotent cells--cells that can become any type of cell in the body, but not the placenta--while the outer shell is made from trophoblasts--cells that eventually form the placenta.

For several years, scientists have been able to convert somatic cells--like skin cells--into pluripotent cells.

In an earlier study conducted at Gladstone, authors Cody Kime and Kiichiro Tomoda were able to convert pluripotent mouse cells from an implanted-like state to a pre-implanted state.

As Kime explains, "over seven years ago, our reprogramming experiments suggested that we had found a way to increase cell potency beyond pluripotency, which was unlikely and had not been seen before.
