Sperm are masters of Tetris packing

Roughly half of all flowering plants are polyploid, meaning that they have more than two sets of chromosomes. Scientists believe polyploidy drives adaptation by giving organisms more genetic diversity. This research compared tetraploid (four copies) and octoploid (eight copies) varieties of switchgrass, and found that octoploid switchgrasses are generalists, able to tolerate a broad range of environmental conditions and expand their range into new areas.
A longitudinal cohort study of persons with a history of injection drug use has found that more people who inject drugs (PWID) are receiving Hepatitis C virus (HCV) treatment, which is associated with significant reductions in liver disease and mortality.
People who add extra salt to their food at the table are at higher risk of dying prematurely from any cause, according to a study of more than 500,000 people, published in the European Heart Journal today (Monday).
One day more than 3000 years ago, someone lost a shoe at the place we today call Langfonne in the Jotunheimen mountains. The shoe is 28 cm long, which roughly corresponds to a modern size 36 or 37. The owner probably considered the shoe to be lost for good, but on 17 September 2007 it was found again – virtually intact.
The same four factors that explain how people change their beliefs on a variety of issues can account for the recent rise in anti-science attitudes, a new review suggests.
The first ever exoplanets were discovered 30 years ago around a rapidly rotating star, called a pulsar. Now, astronomers have revealed that these planets may be incredibly rare.
Producing biomaterials that match the performance of cartilage and tendons has been an elusive goal for scientists, but a new material created at Cornell demonstrates a promising new approach to mimicking natural tissue.
Triptans, a commonly prescribed class of migraine drugs, may also be useful in treating obesity, a new study by scientists at UT Southwestern suggests. In studies on obese mice, a daily dose of a triptan led animals to eat less food and lose weight over the course of a month, the team reported in the Journal of Experimental Medicine.
The amount of carbon stored by microscopic plankton will increase in the coming century, predict researchers at the University of Bristol and the National Oceanography Centre (NOC).
By analyzing noble gas isotope data, a scientist determined that the ancient plume mantle had a water concentration that was a factor of 4 to 250 times lower when compared with the water concentration of the upper mantle. The resulting viscosity contrast could have prevented mixing within the mantle, helping to explain certain long-standing mysteries about Earth’s formation and evolution.
After almost two decades of synchrotron experiments, Caltech scientists have captured a clear picture of a cell’s nuclear pores, which are the doors and windows through which critical material in your body flows in and out of the cell’s nucleus. These findings could lead to new treatments of certain cancers, autoimmune diseases and heart conditions.
Black households in the U.S. faced higher and more volatile inflation compared to white households from 2004 to 2020, reveals new research from the University of California San Diego’s School of Global Policy and Strategy.
A research group led by Osaka University have discovered a mechanism by which cancerous epithelial cells can evade the usual cellular defenses to become invasive.
The July issue of SLAS Discovery is now available Open Access on ScienceDirect.
A unique Mount Sinai study focused on a multi-ethnic, underserved community in New York City shows that young Black adults are twice as likely to have atherosclerosis as similarly situated young Hispanic adults.
Mount Sinai study can help guide proper treatment course for patients depending on heart function and severity of heart damage
Most patients in the study mounted immune responses after a booster dose, and no patient with antibody responses died from COVID-19.
Buildings made of porous rock can weather over the years. Now, for the first time, scientists at TU Wien (Vienna) have studied in detail how silicate nanoparticles can help save them.
Stony Brook University scientists provide researchers investigating the evolutionary past of ancient hominins an important and foundational message in a paper published in Nature Ecology & Evolution. That is – conclusions drawn from evolutionary models are only as good as the data upon which they are based.
