Will AI help Europe catch up with US tech titans like Google, Apple?

Posted by in categories: climatology, robotics/AI, sustainability

While European nations are ahead on dimensions like equality, social progress, and climate change redressal, they lack technological advancements in comparison to the United States. The European region, including the UK, still lacks the investment and culture necessary for a startup ecosystem prevalent in California’s Silicon Valley.

The Valley is a globally recognized hub for technology and innovation. Many of the world’s leading technology companies, like Apple, Google, Facebook, and Amazon, are based there. However, Europe also has notable… More.


Silicon Valley overshadows the EU in tech, but with the advent of new-age artificial intelligence, Europe’s leading entrepreneurs think it could offer the Euro startup ecosystem to be a key player in the race.

Minnesota Man Sets World Record With 2,749-Pound Pumpkin

Posted by in category: space

Travis Gienger is a talented gourd-grower, and he’s used to earning accolades for his colossal pumpkins. Since 2020, he’s won three of the past four World Championship Pumpkin Weigh-Off competitions—and this year’s entry topped them all. Weighing in at 2,749 pounds, Gienger’s gourd has set a new world record for the heaviest pumpkin.

Nicknamed “Michael Jordan,” the pumpkin took the crown during the annual championship in Half Moon Bay, California, this week, reports Heidi Raschke of Minnesota Public Radio (MPR). It easily beat out last year’s champion—Gienger’s own 2,560-pounder, which set a new North American record and which he later turned into the world’s largest jack o’lantern.

“I was not expecting that. It was quite the feeling,” says Gienger, a 43-year-old landscape and horticulture teacher at Anoka Technical College, to the Associated Press (AP). He has been growing pumpkins since he was a teenager, following in the footsteps of his father.

Quantum Breakthrough: Scientists Rethink the Nature of Reality

Posted by in categories: innovation, quantum physics

Whenever measurement precision nears the uncertainty limit set by quantum mechanics, the results become dependent on the interaction dynamics between the measuring device and the system. This finding may explain why quantum experiments often produce conflicting results and may contradict basic assumptions regarding physical reality.

Two quantum physicists from Hiroshima University recently analyzed the dynamics of a measurement interaction, where the value of a physical property is identified with a quantitative change in the meter state. This is a difficult problem, because quantum theory does not identify the value of a physical property unless the system is in a so-called “eigenstate” of that physical property, a very small set of special quantum states for which the physical property has a fixed value.

The researchers solved this fundamental problem by combining information about the past of the system with information about its future in a description of the dynamics of the system during the measurement interaction, demonstrating that the observable values of a physical system depend on the dynamics of the measurement interaction by which they are observed.

Biosynthesis of magnetic sensor in magnetic bacteria revealed through expression of foreign proteins

Posted by in categories: electronics, particle physics

A German-French research team led by Bayreuth microbiologist Dirk Schüler presents new findings on the functionality of proteins in magnetic bacteria in the journal mBio. The research is based on previous results published recently in the same journal.

In this study, the Bayreuth scientists used of the species Magnetospirillum gryphiswaldense to decipher the function of genes that are presumably involved in the biosynthesis of magnetosomes in other magnetic bacteria that are difficult to access.

Magnetic bacteria contain consisting of nanocrystals of an iron mineral inside their cells. These organelle-like particles are known in research as magnetosomes. Like links in a chain, well over 20 of these particles are regularly lined up one after the other. The magnetic moments of the individual crystals add up so that the chain—similar to a compass needle—has the function of a magnetic sensor: It aligns the bacterial cell in the relatively weak magnetic field of the Earth.

How a single synapse transmits both visual and subconscious information to the brain of fruit flies

Posted by in categories: biological, life extension, neuroscience

Research led by Peking University, China, has discovered a single type of retinal photoreceptor cell in Drosophila (fruit fly) is involved in both visual perception and circadian photoentrainment by co-releasing histamine and acetylcholine at the first visual synapse.

In a paper, “A single photoreceptor splits perception and entrainment by cotransmission,” published in Nature, the team details the discovery that the Drosophila visual system segregates and circadian photoentrainment by co-transmitting two neurotransmitters, histamine and acetylcholine, in the R8 cells.

Light detection involves capturing signals through photoreceptors in the eye, which are essential for image formation and subconscious visual functions, such as regulating biological rhythms according to the daily light-dark cycle (photoentrainment of the ). The optical system has distinct pathways for image formation (based on local contrast) and non-image-related tasks (based on global irradiance).

Clear holographic imaging in turbulent environments

Posted by in categories: innovation, robotics/AI

Holographic imaging has always been challenged by unpredictable distortions in dynamic environments. Traditional deep learning methods often struggle to adapt to diverse scenes due to their reliance on specific data conditions.

To tackle this problem, researchers at Zhejiang University delved into the intersection of optics and , uncovering the key role of physical priors in ensuring the alignment of data and pre-trained models.

They explored the impact of spatial and on holographic imaging and proposed an innovative method, TWC-Swin, to restore high-quality holographic images in the presence of these disturbances. Their research, titled “Harnessing the magic of light: spatial coherence instructed swin transformer for universal holographic imaging,” is reported in the journal Advanced Photonics.

Research claims novel algorithm can exactly compute information rate for any system

Posted by in category: information science

75 years ago Claude Shannon, the “father of information theory,” showed how information transmission can be quantified mathematically, namely via the so-called information transmission rate.

Yet, until now this quantity could only be computed approximately. AMOLF researchers Manuel Reinhardt and Pieter Rein ten Wolde, together with a collaborator from Vienna, have now developed a simulation technique that—for the first time—makes it possible to compute the information rate exactly for any system. The researchers have published their results in the journal Physical Review X.

To calculate the information rate exactly, the AMOLF researchers developed a novel simulation algorithm. It works by representing a complex physical system as an interconnected network that transmits the information via connections between its nodes. The researchers hypothesized that by looking at all the different paths the information can take through this network, it should be possible to obtain the information rate exactly.

First-ever wireless device developed to make magnetism appear in non-magnetic materials

Posted by in categories: biotech/medical, computing

Researchers at the UAB and ICMAB have succeeded in bringing wireless technology to the fundamental level of magnetic devices. The emergence and control of magnetic properties in cobalt nitride layers (initially non-magnetic) by voltage, without connecting the sample to electrical wiring, represents a paradigm shift that can facilitate the creation of magnetic nanorobots for biomedicine and computing systems where basic information management processes do not require wiring.

The study was recently published in the latest issue of Nature Communications.

Electronic devices rely on manipulating the electrical and magnetic properties of components, whether for computing or storing information, among other processes. Controlling magnetism using voltage instead of has become a very important control method to improve in many devices, since currents heat up circuits. In recent years, much research has been carried out to implement protocols for applying voltages to carry out this control, but always through directly on the materials.

Webb Telescope sees explosion 1 million times brighter than the Milky Way

Posted by in categories: cosmology, physics

This particular burst, called GRB 230307A, was likely created when two neutron stars — the incredibly dense remnants of stars after a supernova — merged in a galaxy about one billion light-years away. In addition to releasing the gamma-ray burst, the merger created a kilonova, a rare explosion that occurs when a neutron star merges with another neutron star or a black hole, according to a study published Wednesday in the journal Nature.

The Space Telescope Science Institute in Baltimore is the mission operations center for the telescope. It launched last in 2021 from French Guiana.

“There are only a mere handful of known kilonovas, and this is the first time we have been able to look at the aftermath of a kilonova with the James Webb Space Telescope,” said lead study author Andrew Levan, astrophysics professor at Radboud University in the Netherlands. Levan was also part of the team that made the first detection of a kilonova in 2013.
