reforestation models have been over exaggerated — and not by a small factor — but by as many as three times of a factor. The goal set by the Paris Agreement in 2015 for countries to limit their global warming to 1.5 degrees is now close to being surpassed.
Conventional metals cannot conduct light in their interiors, but scientists have discovered that in the quantum metal ZrSiSe, electrons can give rise to plasmons. These are collective oscillations in a material that are strong and long lived, and they can combine with photons to form new modes called polaritons that can carry photons along zig-zag paths in the material.
Potassium-40 usually decays to calcium-40, but about 10 percent of the time it decays to argon-40 through electron capture. One variant of this decay path ends in argon-40 in its ground state. The rate of this decay is important for using argon-40 to determine the age of geologic features and studying neutrinoless double beta decay. Researchers recently made the first direct observations of this very rare but critical decay path.
The quark Sivers function describes much of the physics of how quarks are distributed in a proton whose rotation is perpendicular to its direction of motion. This function shows whether more quarks in the proton move to the right than to the left of the plane created by the proton’s velocity and the direction of the proton’s rotation (spin) axis. Scientists have found a new theoretical contribution to the Sivers function of the quarks carrying a small fraction of the proton’s momentum.
Research led by scientists at the Department of Energy’s Oak Ridge National Laboratory has demonstrated that small changes in the isotopic content of thin semiconductor materials can influence their optical and electronic properties, possibly opening the way to new and advanced designs with the semiconductors.

A team of University of Miami scientists and others recently spent weeks in the Arctic region studying marine cold-air outbreaks and how the clouds they produce can lead to extreme weather events and may be interacting with the rapidly warming Arctic.
Tantalum superconducting material shows great promise for making qubits. When an oxide layer forms on the surface of tantalum, it can lead to quantum decoherence. In this study, researchers used scanning transmission electron microscopy (STEM) and computer modeling to investigate the structure of superconducting tantalum film. This helped them build an atomic-level understanding of the crystalline lattice of tantalum metal and the oxide that forms on its surface.
X-ray bursts occur on the surface of a neutron star as it absorbs material from a companion star. This absorption initiates a cascade of thermonuclear reactions that create atoms of heavy chemical elements on the surface of a neutron star. Researchers have directly measured one of these reactions, finding it to be four times higher than the previous direct measurement.
The Wistar Institute assistant professor Dr. Filippo Veglia has discovered a key mechanism of how glioblastoma — a serious and often fatal brain cancer — suppresses the immune system so that the tumor can grow unimpeded by the body’s defenses.

An environmental archaeologist at the University of Nebraska-Lincoln, Perdikaris maintains a research station on the Caribbean island of Barbuda where, despite the species’ status as national animal and cultural emblem, the fallow deer population could face extinction as a result of over-hunting and massive environmental destruction caused by Hurricane Irma in 2017.
Scientists at the Department of Energy’s Oak Ridge National Laboratory have developed lubricant additives that protect both water turbine equipment and the surrounding environment.
Using his platform composed of carbon nanotubes and gold nanoparticles, Professor Alexander Star added antibodies to detect the opioid. His sensor can also distinguish fentanyl from several other common opioids.
مدينة روتشستر، ولاية مينيسوتا – معظم التكتلات أو العُقيدات في الغدة الدرقية، التي هي غدة في عنقك، غير ضارة ولا تحتاج إلى علاج. ولكنها في بعض الأحيان قد تصبح أكبر وتسبب مشكلات مثل عُسر البلع. في هذه الحالات قد يحتاج الأطباء إلى إجراء جراحة لإزالتها.
Vicky Barone, assistant professor of economics at the University Notre Dame, researched the origins and development of the opioid epidemic and found that the unregulated marketing of potent painkillers led to increased access to prescription opioids and subsequent overdose mortalities.
New study led by Univ. of Leicester & Cooper Medical School of Rowan Univ. finds early patching improves treatment for childhood 'lazy eye' (amblyopia). Published in Lancet. Optimizing care for young patients.
New research shows how tiny plant-like organisms hitch a ride on ocean currents to reach darker and deeper depths, where they impact carbon cycling and microbial dynamics in the subtropical oceans.
Working with human breast and lung cells, Johns Hopkins Medicine scientists say they have charted a molecular pathway that can lure cells down a hazardous path of duplicating their genome too many times, a hallmark of cancer cells.
• Two complementary research articles, published simultaneously in the journals Science and Cell Stem Cell by a team of scientists from the UPF and IRB Barcelona, reveal that central and peripheral circadian clocks coordinate to regulate the daily activity of skin and muscles. • The coordination between the two clocks (central and peripheral) guarantees 50% of the circadian functions of tissues, including vital processes such as the cell cycle, DNA repair, mitochondrial activity, and metabolism. • Synchronisation between the central brain clock and peripheral ones prevents premature muscle ageing and improves muscle function, suggesting new strategies to tackle age-related decline through circadian rhythm modulation.

Many pancreatic tumors are like malignant fortresses, surrounded by a dense matrix of collagen and other tissue that shields them from immune cells and immunotherapies that have been effective in treating other cancers. Employing bacteria to infiltrate that cancerous fortification and deliver these drugs could aid treatment for pancreatic cancer, according to newly published findings from a team of University of Wisconsin–Madison researchers.
Most analyses point to agriculture as the major source of nitrous oxide (N2O) globally. But there are a lot of variables within agriculture that can affect emissions. A recent University of Illinois Urbana-Champaign study provides a comprehensive accounting for these factors, finding, among other things, that long-term no-till management can effectively cut N2O emissions.
On April 23, 2024, the Federal Trade Commission (FTC) announced a ruling banning most noncompete agreements (NCA) nationwide which cites a paper co-authored by a researcher at The University of Alabama in Huntsville (UAH). Dr. Ege Can in the College of Business at UAH, a part of the University of Alabama System, studied the impact of NCAs on entrepreneurship, highlighting how banning NCAs could boost business innovation.

For most smokers, quitting on the first attempt is likely to be unsuccessful, but a new study from The University of Texas MD Anderson Cancer Center found patients were more likely to quit if their cessation regimen was altered and doses were increased. Researchers also found that varenicline, a cessation medication, was more effective than combined nicotine replacement therapy (CNRT), such as patches or lozenges.
