By analyzing root systems of different plants scientists  have found the key to modifying crops so that they can survive longer drought periods. In the research they looked at just 3 different plants, but scientists believe that the same principles can be applied to other plants as well.

The radio waves from WiFi are all around us. In a new experiment a research team from the National University of Singapore (NUS) and Japan's Tohoku University (TU) found a way to use extra energy to power small electronics. This could be used in everyday life to help to minimize electrical waste.


Pink placebo: Fake energy drink makes people run faster, further
A study suggests that the effectiveness of sports drinks may depend in part on their color. Runners who rinsed with a pink liquid ran better than those who consumed the same but colorless drink. Improvement in their performance is likely due to a placebo effect. The " placebo effect " is real. It's the name for a strange phenomenon that most notably occurs during clinical trials. People who are g
The importance of DNA compaction in tissue formation
Scientists led by Dr. Salvador Aznar-Benitah, head of the Stem Cells and Cancer laboratory at IRB Barcelona, have described the alterations that occur during mammary gland formation when heterochromatin (the part of DNA that does not actively produce proteins) is poorly regulated. The results, which have been published in the journal Cell Stem Cell, indicate that incorrect DNA packaging makes retr
Ability to alter color and ripening rates of tomatoes provides novel opportunity for crop improvements
Scientists at the University of Oxford's Department of Plant Sciences have discovered how the overall process of fruit ripening in tomato (including color changes and softening) can be changed –speeded up or slowed down—by modifying the expression of a single protein located in subcellular organelles called the plastids.
COVID-19 testing method gives results within one second
The COVID-19 pandemic made it clear technological innovations were urgently needed to detect, treat, and prevent the SARS-CoV-2 virus. A year and a half into this epidemic, waves of successive outbreaks and the dire need for new medical solutions—especially testing—continue to exist.
Land can retain about 1/4 monthly precipitation
Estimating freshwater storage capability (FSC) is a challenge due to few observation opportunities and methods to measure and quantify FSC. A new study shows that on average, global land surfaces can retain over one quarter of monthly precipitation based on the Gravity Recovery and Climate Experiment observation.
New species formed when the Mediterranean dried up
A new study may have uncovered why wall lizards have become the most successful reptile in the Mediterranean region. The results reveal how drastic changes in sea levels and climate 6 million years ago affected species formation in the area. The researchers believe they can now explain why the lizards became so diverse and widespread, something that has puzzled biologists since the 19th century. T
Modular photoswitch cpLOV2 developed for optogenetic engineering
Recently, Prof. WANG Junfeng from the High Magnetic Field Laboratory of the Hefei Institutes of Physical Science (HFIPS), together with international scholars, developed a novel circular permutated light-oxygen-voltage 2 (LOV2) to expand the repertoire of genetically encoded photoswitches, which will accelerate the design of novel optogenetic devices. The result was published in Nature Chemical Bi
Grazing management of salt marshes contributes to coastal defense
Combining natural salt marsh habitats with conventional dikes may provide a more sustainable alternative for fully engineered flood protection. Researchers of the University of Groningen and the Royal Netherlands Institute for Sea Research studied how salt marsh management can be optimized for coastal defence purposes. They found that grazing by both cattle and small herbivores such as geese and h
Electric cars: Special dyes could prevent unnecessary motor replacements
In the near future dyes in electric motors might indicate when cable insulation is becoming brittle and the motor needs replacing. Scientists at Martin Luther University Halle-Wittenberg (MLU), together with ELANTAS, a division of the specialty chemicals group ALTANA, have developed a new process that enables the dyes to be directly integrated into the insulation. By changing colour, they reveal h
Turn problems into opportunities: Photorespiration for improved plant metabolism
In the quest for more sustainable agriculture, engineered crops that tackle photorespiration, a highly energy-consuming process, hold enormous potential. Researchers from the EU-funded Gain4Crops project have now succeeded in engineering a solution that connects photorespiration and C4 metabolism, two of the main targets in plant metabolism. This first proof of concept opens the door to strategic
Former US Military Official: Unidentified Objects “a Hundred to a Thousand Years” Ahead of Our Tech
The Pentagon is currently making a big show of taking “unidentified aerial phenomena” (UAPs) seriously after a string of first-hand accounts emerged from Navy pilots. The crux of the saga is that since at least as early as 2004, military personnel have made several sightings of unfamiliar objects that acted in seemingly inexplicable ways. It’s hotly debated whether the encounters were with unknow
Spintronics: Improving electronics with finer spin control
Scientists in Korea have found a new way to control the alignment state of magnetic atoms in an antiferromagnetic material, showing promise for the development of tiny sensors and memory devices. Researchers at the Daegu Gyeongbuk Institute of Science and Technology (DGIST) describe their new approach featuring a controllable exchange bias effect, which enables the asymmetric magnetic actions of d
Crystalline supermirrors for trace gas detection in environmental science and medicine
In an international cooperation with partners from industry and research, physicists from the University of Vienna, together with Thorlabs, the National Institute of Standards and Technology (NIST), and the University of Kansas, have now succeeded for the first time in demonstrating high-performance laser mirrors in the sensing-relevant mid-infrared wavelength range that absorb less than ten out o
'Bite' defects revealed in bottom-up graphene nanoribbons
Collaboration between two NCCR MARVEL labs has identified a new type of defect as the most common source of disorder in on-surface synthesized graphene nanoribbons (GNRs). The researchers identified the atomic structure of these "bite" defects and investigated their effect on quantum electronic transport in two different types of GNR. They also established guidelines for minimizing the detrimental
LHAASO discovers a dozen PeVatrons and photons exceeding 1 PeV and launches ultra-high-energy gamma
China's Large High Altitude Air Shower Observatory (LHAASO)–one of the country's key national science and technology infrastructure facilities–has found a dozen ultra-high-energy (UHE) cosmic accelerators within the Milky Way. It has also detected photons with energies exceeding 1 peta-electron-volt (quadrillion electron-volts or PeV), including one at 1.4 PeV. The latter is the highest energy p
Colonization of the Antilles by South American fauna: Giant sunken islands as a passageway
Fossils of land animals from South America have been found in the Antilles, but how did these animals get there? According to scientists from the CNRS, l'Université des Antilles, l'Université de Montpellier and d'Université Côte d'Azur, land emerged in this region and then disappeared beneath the waves for millions of years, explaining how some species were able to migrate to the Antilles. This st
Researchers first achieve quantum information masking experimentally
The research team, led by Academician GUO Guangcan from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences, collaborating with LI Bo from Shangrao Normal University and CHEN Jingling from Nankai University, achieved the masking of optical quantum information. The researchers concealed quantum information into non-local quantum entangled states. The study was pu
Towards a universal flu vaccine for Indigenous populations
Researchers have identified specific influenza targets that could be used to better protect Indigenous people from experiencing severe influenza disease through a universal, T cell-based vaccine.In a collaboration with Monash Biomedicine Discovery Institute, Menzies School of Health Research and CQUniversity, Peter Doherty Institute for Infection and Immunity (Doherty Institute) researchers took a
