Researchers from the NASA Jet Propulsion Laboratory (JPL) and the University of Bath have developed a satellite-based early warning system that could spot tiny movements in bridges that indicate they could collapse.

Combining data from a new generation of satellites with a sophisticated algorithm, the monitoring system could be used by governments or developers to act as a warning system ensuring large-scale infrastructure projects are safe.

The role of Hox genes in changing the layout of different body parts during evolution has been challenged by a study led by researchers out of the University of Pittsburgh's Department of Biological Sciences.

Hox genes are vital to developing differences in repeated body parts such as vertebrae, limbs, or digits in most animal species, including human beings. Ever since their discovery, scientists have thought that modifications to Hox genes could be the primary way that the animal body plan has been altered during evolution.

Dolomite is widely in the metal industry as a fireproof material and in construction, such as for joint grouting in panel building. Of course, dolomite is also known as a collector of hydrocarbons.

Scientists from the Skoltech Center for Energy Science and Technology, the Institute for Problems of Chemical Physics of RAS, and the Department of Chemistry of MSU presented solar cells based on conjugated polymers and fullerene derivatives, that demonstrated record-high radiation stability and withstand gamma radiation of >6,000 Gy raising hopes for their stable operation on the near-earth orbit during 10 years or even longer. The results of the study were published in ACS Applied Materials & Interfaces.

Manuel Eichelberger and Simon Tanner, two ETH doctoral students, store data in music. This means, for example, that background music can contain the access data for the local Wi-Fi network, and a mobile phone's built-in microphone can receive this data. "That would be handy in a hotel room," Tanner says, "since guests would get access to the hotel Wi-Fi without having to enter a password on their device."

Osaka, Japan -- A "vacuum" is generally thought to be nothing but empty space. But in fact, a vacuum is filled with "virtual particle-antiparticle pairs" of electrons and positrons that are continuously created and annihilated in unimaginably short time-scales.

Fontainebleau (France), Singapore, Abu Dhabi, 9 July 2019: Behavioural nudges have emerged as the best way to improve healthy eating, according to a new paper by Pierre Chandon, Professor of Marketing at INSEAD, and Romain Cadario, Assistant Professor of Marketing at IÉSEG School of Management.

Tooth decay is among the costliest and most widespread bacterial diseases. Virulent bacteria cause the acidification of tooth enamel and dentin, which, in turn, causes secondary tooth decay.

WASHINGTON -- Researchers at the U.S. Naval Research Laboratory (NRL) developed a new technique that could enable future advancements in quantum technology.

The technique squeezes quantum dots, tiny particles made of thousands of atoms, to emit single photons (individual particles of light) with precisely the same color and with positions that can be less than a millionth of a meter apart.

Scientists at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan have developed the first microchip valve powered by living cells. Earthworm muscle tissue allowed for a high contractile force that could be sustained for minutes, and unlike electrically controlled valves, did not require any external power source such as batteries.

BEER-SHEVA, Israel...July 9, 2019 - Dogs can be trained to respond to haptic vibration commands while wearing a modified canine vest developed by an interdisciplinary research team at Ben-Gurion University of the Negev (BGU).

The paper, "Vibrotactile Vest for Remote Human-Dog Communication," will be presented at the World Haptics Conference on July 12 in Tokyo, Japan. Haptics technology simulates the senses of touch and motion, which is especially helpful in a remote operation or computer simulation where the user is not able to interact with and feel physical objects.

In work that could open a floodgate of future applications for a new class of nanomaterials known as MXenes (pronounced "Maxines"), researchers from Texas A&M University have discovered a simple, inexpensive way to prevent the materials' rapid degradation.

Two-dimensional MXene nanosheets have promise in applications ranging from energy storage to water purification. However, MXenes have an Achilles' heel: they rapidly degrade when kept in the open.

New findings show how a genetically aberrant, fused protein promotes a rare form of liver cancer in adolescents and young adults. The researchers also saw that a certain mix of drugs could target the fused protein and the enzymes that it recruits. In the lab, this drug combination slowed down the uncontrolled growth of cells carrying the liver cancer mutation.

While the potential treatment approach needs further testing in animal models and in cancerous human liver cells, the early results are encouraging. This preliminary research project was published in eLife.

Human cytomegalovirus (HCMV) may not be a household name as far as viruses go, but according to Xiaoping Zhu, professor and chair in Veterinary Medicine at UMD, half of the population walking around campus is likely to be a carrier. Once contracted, it lays dormant in your body for the rest of your life and can flare up whenever your immune system is severely compromised, giving you flu-like symptoms. This becomes a severe problem for people who already have weakened immune systems, for example the very young, old, pregnant women, organ transplant recipients, or HIV/AIDS patients.

Are our personalities and behaviors shaped more by our genes or our circumstances? While this age-old "nature vs. nurture" question continues to confound us and fuel debates, a growing body of evidence from research conducted over recent decades suggests that parental environment can have a profound impact on future generations.
