At the 2013 Annual Meeting of the European Nuclear Medi-cine Association (EANM) in Lyon, Springer launched a newcompanion journal to the European Journal of Nuclear Med-icine and Molecular Imaging (EJNMMI):the EJNMMI Phys-ics journal. EJNMMI Physics will be a partner journal ofEJNMMI Research, of which Angelika Bischof Delaloye hasbeentheeditor-in-chiefsince2011[1]. Thewell-versed readermay stop here with a grunting sound: “YAJ! ” (“yet anotherjournal”). However, there is more to this announcement.The development of nuclear medicine is indebted to manycontributions from physicists, including the discovery of ra-dioactivity by Henri Becquerel, the isolation of radioactiveisotopes by Marie Sklodowska-Curie, the discovery of thepositron by Carl David Anderson and the discovery of theneutron by James Chadwick, subsequently leading to thediscovery of artificial radioactivity by Irene and FredericJoliot-Curie, who received the Nobel Prize for Chemistry in1935.Itisperhapssurprising,therefore,thatatpresentthereisno journal dedicated to the field of physics in nuclear medi-cine, and it is very noticeable that such papers are scatteredacross a range of journals that either cover general physics inmedicine or are more focussed on clinical issues. With theincreasing emphasis on molecular imaging and personalisedmedicine, physics can only become more central to futuredevelopments, and a platform is needed to focus such ideas.EJNMMI Physics will fill that gap by providing a publica-tion platform for the exchange of scientifically sound infor-mationonphysicsand physics matters inthe realm ofnuclearmedicine. In recognition of today’s multi-disciplinary ap-proach to nuclear medicine and nuclear medicine physics,the journal will publish original materials and studies with afocus on applied physics, mathematics and multi-modalityimaging instrumentation as well as imaging system engineer-ing and prototyping in nuclear medicine. This includesphysics-drivenapproachesoralgorithmssupportedbyphysicsthatfosterearlyclinicaladoptionofnuclearmedicineimagingand therapy regimens.The journal is open for a variety of contributions, rangingfrom original articles and short communicationsto, for exam-ple, artefact reports that will describe both a methodologicalproblem leading to a visual or quantitative distortion of nu-clear medicine imaging and a solution to the problem. Inaddition, opinion papers, pictorial assays and review articlesaddressing controversies and timely developments will bepublished, relevant to both nuclear medicine physics andinstrumentation. One section, “Young Investigator Reports ”,will provide young medical physicists with a submissioncategory suitable for summary reports of their research activ-itiesaspartoftheirthesiswork.Thisjournalisnotintendedtoreplace theEJNMMIas the publication of choicefor physics-related articles that are of interest to the wider clinically

At WIRED Health, pioneering Alzheimer's researcher John Hardy outlined the stakes—and next steps—of where treatment is headed next

Crabs’ famous sideways walk may trace back to a single evolutionary moment 200 million years ago。 Researchers found that most modern crabs inherited this trait from one ancestor—and never looked back。 The movement likely gave them an edge, helping them dodge predators with quick, unpredictable bursts

For decades, psychologists have debated whether the human mind can be explained by one unified theory or must be broken into separate parts like memory and attention。 A recent AI model called Centaur seemed to offer a breakthrough, claiming it could mimic human thinking across 160 different cognitive tasks。 But new research is challenging that bold

In a striking glimpse into extreme physics, scientists have captured the split-second chaos that unfolds when powerful laser flashes blast matter into a superheated plasma。 By combining two cutting-edge lasers, researchers were able to track how copper atoms lose and regain electrons in trillionths of a second, creating and dissolving highly charge

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has been pushed even further。 For the first time, researchers have observed wave-like interference in positronium, an exotic “atom” made of an electron and its antimatter partner, a positron。 This breakthrough not only strengthen

A breakthrough in brain-inspired computing could make today’s energy-hungry AI systems far more efficient。 Researchers have engineered a new nanoelectronic device using a modified form of hafnium oxide that mimics how neurons process and store information at the same time。 Unlike conventional chips that waste energy moving data back and forth, this

Researchers have, for the first time, directly visualized how electronic patterns known as charge density waves evolve across a phase transition。 Using cutting-edge microscopy, they found these patterns form unevenly, breaking into patches influenced by tiny structural distortions。 Unexpectedly, small pockets of order persist even above the transit

Two of the most dangerous fault systems on the U。 West Coast may be more connected than scientists once thought。 New research suggests the Cascadia subduction zone and the San Andreas fault can “sync up,” triggering earthquakes within minutes or hours of each other

Scientists have discovered a way to help the brain clean itself of harmful Alzheimer’s plaques by activating its own support cells。 By increasing a protein called Sox9, researchers were able to boost the activity of astrocytes, star shaped cells that help maintain brain health。 In mice that already showed memory problems, this approach reduced plaq

Osteoarthritis has no cure, but researchers have developed new therapies that help aging or damaged joints repair themselves in a matter of weeks

Australia’s famous Twelve Apostles didn’t just erode into existence—they were slowly pushed up from the ocean floor by powerful tectonic forces over millions of years, new research reveals。 Scientists discovered that these towering limestone stacks act like a natural time capsule, preserving clues about ancient climates, sea levels, and even life f

In the chaotic first moments after the Big Bang, ripples in spacetime may have done more than just echo through the cosmos—they could have helped create dark matter itself。 New research suggests that faint, ancient gravitational waves might have transformed into particles that eventually became the invisible substance shaping galaxies today

Scientists have finally cracked one of the biggest mysteries in the senses: how smell is organized。 By mapping millions of neurons in mice, researchers discovered that smell receptors in the nose aren’t random at all—they’re arranged in neat, overlapping stripes based on receptor type, forming a hidden structure scientists never knew existed。 Even

How research linking climate change and extreme weather events is being used in lawsuits

Deep beneath the Southern Ocean, a quiet but alarming shift is underway: warm water is creeping closer to Antarctica, and scientists are now seeing it clearly for the first time。 By combining decades of ship data with robotic float measurements and machine learning, researchers uncovered that a massive pool of heat—circumpolar deep water—has expand
