In research that may be a step forward toward finding personalized treatments for Tourette disorder, scientists at Rutgers University–New Brunswick have bred mice that exhibit some of the same behaviors and brain abnormalities seen in humans with the disorder. As reported in the Proceedings of the National Academy of Sciences, the researchers, using a technique known as CRISPR/Cas9 DNA editing, inserted the same genetic mutations found in humans with Tourette disorder into the corresponding genes in mouse embryos.
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.

Cooking on your gas stove can emit more nano-sized particles into the air than vehicles that run on gas or diesel, possibly increasing your risk of developing asthma or other respiratory illnesses, a new Purdue University study has found.
Global polls typically show that people in industrialized countries where incomes are relatively high report greater levels of satisfaction with life than those in low-income countries.
Vitamin B12 deficiency in people can cause a slew of health problems and even become fatal. Until now, the same deficiencies were thought to impact certain types of algae, as well.
Scientists from Stanley Manne Children’s Research Institute at Ann & Robert H. Lurie Children’s Hospital of Chicago and Northwestern University succeeded in regenerating fully functional urinary bladder tissue in a long-term study utilizing a non-human primate model.
A new technology to increase visibility of cancer cells to the immune system using CRISPR has been developed, and could lead to a new way to treat cancer.
Scientists from the National University of Singapore (NUS) employed novel statistical methods to reveal the extent of biodiversity loss in Singapore over the past two centuries.
Working with mammalian retinal cells, neuroscientists at Johns Hopkins Medicine have shown that, unlike most light-sensing cells (photoreceptors) in the retina, one special type uses two different pathways at the same time to transmit electrical “vision” signals to the brain.
A new computational framework created by Oak Ridge National Laboratory researchers is accelerating their understanding of who’s in, who’s out, who’s hot and who’s not in the soil microbiome, where fungi often act as bodyguards for plants, keeping friends close and foes at bay.
Major cities on the U.S. Atlantic coast are sinking, in some cases as much as 5 millimeters per year – a decline at the ocean’s edge that well outpaces global sea level rise, confirms new research from Virginia Tech and the U.S. Geological Survey. Particularly hard hit population centers such as New York City and Long Island, Baltimore, and Virginia Beach and Norfolk are seeing areas of rapid “subsidence,” or sinking land, alongside more slowly sinking or relatively stable ground, increasing the risk to roadways, runways, building foundations, rail lines, and pipelines, according to a study published today in the Proceedings of the National Academies of Sciences.
Frequent insulin injections are an unpleasant, albeit necessary reality for many patients with type 1 diabetes. However, new technology could create a different reality for these patients by treating the disease in one fell swoop.
Using lab-made cells, Harvard Med researchers identify how the immune system neutralizes herpesvirus.
Study maps, for the first time, the maneuvers used by virus and host in the cell nucleus.
Findings could inform design of new treatments for herpes and other viruses that replicate in the same way.
It’s fairly well-known that a drought in southern California in the mid-1970s led to a ban on filling backyard swimming pools, and these empty pools became playgrounds for freestyle skateboarders in the greater Los Angeles area.
Living through a historic pandemic while handling the stress of the first year of college sent one-third of students in a new study into clinical depression. That’s double the percentage seen in previous years of the same study.
The lab of Yongchao C. Ma, PhD, at Stanley Manne Children’s Research Institute at Ann & Robert H. Lurie Children’s Hospital of Chicago uncovered a novel mechanism that leads to motor neuron degeneration in spinal muscular atrophy (SMA).
A new PNAS Nexus study led by scientists from the USDA Agricultural Research Service (USDA-ARS) and the University of Illinois Urbana-Champaign takes a retrospective look at glyphosate efficacy after tolerant crops were commercialized.
A new study reveals deep-sea corals and sponges produce the ROS superoxide, meaning these chemicals have a string of previously unknown effects on ocean life.
A team of Stony Brook University researchers led by Gábor Balázsi, PhD, have been testing drug resistance with mammalian cell lines. Their latest investigation reveals that by taking a part of a DNA amplification from a cell, which causes resistance, and placing it back in, actually stops the drug resistance. Their findings will be published this week in PNAS.
Jennifer Oyler-Yaniv is studying human diseases to learn about the immune system. She hopes that diseases such as cancer will reveal fundamental principles of how immune cells communicate

This most recent work from the Umen lab gets at the critical control mechanism for sex determination in single-celled and multicellular algae. The capacity to produce distinct mating types (e.g. male and female) is the foundation for reshuffling of genetic material within a species, which maintains genetic diversity and capacity to adapt in different environments.
A Cornell-led collaboration demonstrated that by inhibiting a certain protein they can reverse the effects of lymphedema, creating a potential treatment for a condition that is estimated to affect up to 150 million people worldwide.
In a groundbreaking study, a team of Georgia Tech researchers has unveiled a remarkable discovery: the identification of novel bacterial proteins that play a vital role in the formation and stability of methane clathrates, which trap gigatons of greenhouse gas beneath the seafloor. These newfound proteins not only suppress methane clathrate growth as effectively as toxic chemicals used in drilling but also prove to be eco-friendly and scalable. This innovative breakthrough not only promises to enhance environmental safety in natural gas transportation but also sheds light on the potential for similar biomolecules to support life beyond Earth.
