Respected snake researcher dies from rattlesnake bite
For the entire 64 years NASA has been around, agency administrators have been forced to answer the dreaded what’s-the-point? question. What’s the point, legislators and taxpayers ask, of spending so much money in space when there are so many problems on Earth? NASA has always had a ready answer, pointing to the generations of Earth-observing satellites it has launched, which have...
Do videos show ivory-billed woodpecker, or is it extinct?
A respected snake researcher who had been making significant discoveries about the species since childhood has died after being bitten by a timber rattler.
Overcoming a major manufacturing constraint
The federal government has been asked to consider at least two videos made in recent years as evidence that ivory-billed woodpeckers may still exist.
Bug eyes and bat sonar: Bioengineers turn to animal kingdom for creation of bionic super 3D cameras
Additive manufacturing (AM) using two-photon polymerization lithography (TPP) has increased in usage in industry and research. Currently, a major constraint of TPP in general and specifically of the material IP-Q (Nanoscribe GmbH, Germany) is the users' limited access to knowledge about material properties. Due to the nature of the process, the elastic properties in particular depend not only on...
Optical microscope strategy allows observers to check electrons moving inside gold
A pair of UCLA bioengineers and a former postdoctoral scholar have developed a new class of bionic 3D camera systems that can mimic flies' multiview vision and bats' natural sonar sensing, resulting in multidimensional imaging with extraordinary depth range that can also scan through blind spots.
How monsoon winds impact climate change by transporting pollutants into the upper atmosphere
A team led by DGIST professor Seo Dae-ha has developed an experimental strategy to control and observe the chemical reaction of a single nanocatalyst using an optical microscope. The work is expected to contribute to catalyst design based on accurate understanding of the photocatalytic reaction through an analysis method that helps understanding the electron excitation phenomenon and transition...
A review article clarifies genotype-independent plant transformation
While the Asian monsoon brings rain that is vital for the agricultural economy of the vast region, it is also known to suck up into the upper atmosphere chemical pollutants that accelerate climate change.
A simple way of sculpting matter into complex shapes
Recently, researchers from North Carolina State University and the Beltsville Agricultural Research Center published the first review of research progress on genotype-independent plant transformation. In this review, researchers discussed recent advances in the use of regulatory genes in plant transformation and regeneration, as well as their potential to facilitate genotype-independent plant...
Parasitic behavior of the root-knot nematode is negatively regulated by root-derived volatiles of C. metuliferus
A new method for shaping matter into complex shapes, with the use of 'twisted' light, has been demonstrated in research at the University of Strathclyde.
New radiolabeling method for personalized cancer treatment
Recently, scientists from the Institute of Vegetables and Flowers of the Chinese Academy of Agricultural Science provided new insights into the correlation between cucurbit root volatiles and root-knot nematode parasitism, paving the way for development of more sustainable cucumber production.
Antarctica's ice shelves could be melting faster than we thought
Researchers from TU Delft have found a new method to efficiently make nano carriers loaded with radioactive salts for both imaging and treatment. Because the assembly of these nano carriers is incredibly simple, the innovation is very suitable for clinical research and treatments of cancer patients. The findings are now published in Advanced Therapeutics.
Matter at extreme conditions of very high temperature and pressure turns out to be remarkably simple and universal
A new model developed by Caltech and JPL researchers suggests that Antarctica's ice shelves may be melting at an accelerated rate, which could eventually contribute to more rapid sea level rise. The model accounts for an often-overlooked narrow ocean current along the Antarctic coast and simulates how rapidly flowing freshwater, melted from the ice shelves, can trap dense warm ocean water at the...
A fresh look into grasslands as carbon sinks
Scientists at Queen Mary University of London have made two discoveries about the behavior of "supercritical matter"—matter at the critical point where the differences between liquids and gases seemingly disappear.
Researchers fabricate cobalt copper catalysts for methane on metal-organic framework
Grasslands have the capability to store carbon, functioning as an important tool in a battle against climate change. While scientific interest in grassland soil for carbon sequestration is not new, researchers from the Chinese Academy of Sciences and Colorado State University have provided a fresh analysis of the existing research on soil carbon sequestration in grasslands. According to the...
Using sound and bubbles to make bandages stickier and longer lasting
The world is highly dependent on fossil fuels to power its industry and transportation. These fossil fuels lead to excessive carbon dioxide emission, which contributes to global warming and ocean acidification. One way to reduce this excessive carbon dioxide emission that is harmful to the environment is through the electroreduction of carbon dioxide into value-added fuels or chemicals using...

Cell chatter tells story of arterial thickening
Researchers have discovered that they can control the stickiness of adhesive bandages using ultrasound waves and bubbles. This breakthrough could lead to new advances in medical adhesives, especially in cases where adhesives are difficult to apply such as on wet skin.
A step towards quantum gravity
Arteries can become thicker due to high blood pressure. However, the cause of this thickening is unclear. TU/e researchers along with colleagues from Trinity College Dublin in Ireland have developed a new computer model to study the arterial thickening in detail. The model shows that both mechanical changes in the artery due to higher blood pressure and cell communication involving so-called...
China claims new world record for strongest steady magnetic field
In Einstein's theory of general relativity, gravity arises when a massive object distorts the fabric of spacetime the way a ball sinks into a piece of stretched cloth. Solving Einstein's equations by using quantities that apply across all space and time coordinates could enable physicists to eventually find their "white whale": a quantum theory of gravity.
First results from the paleomagnetic study of Cumbre Vieja
On August 12, the hybrid magnet of the Steady High Magnetic Field Facility (SHMFF) in Hefei, China, produced a steady field of 45.22 tesla (T), the highest steady magnetic field by a working magnet in the world.
Elephant tweets highlight divide on conservation issues
Josep M. Parés, coordinator of the Geochronology and Geology Program at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), has led the first study of the magnetic properties of the lava and ash produced during the 2021 eruption of the Cumbre Vieja volcano (island of La Palma, Canary Islands, Spain), which has been published in the journal Geosciences.
Will strong and fast-switching artificial muscle be feasible?
An analysis of social media posts has highlighted how attention on Twitter does not align with the most pressing threats to wild elephants, which may have negative consequences for elephant conservation and lead to resentment from local communities that live with elephants.
Nearly 70% of Premier League footballers are abused on Twitter according to AI used to sift through millions of tweets
In the American action movie "Pacific Rim," giant robots called "Jaegers" fight against unknown monsters to save mankind. These robots are equipped with artificial muscles that mimic real living bodies and defeat monsters with power and speed. Research is being conducted on equipping real robots with artificial muscles like the ones shows in the movie. However, the powerful strength and high speed...
As the new Premier League football season gets underway, a few things are certain. There will be goals, drama and excitement, and unfortunately, players will be subjected to vile abuse on social media.
