Saki monkeys get screen time for more control over their lives in captivity
Scientists have designed and built an on-demand video device for white-faced saki monkeys to activate as and when they like. It’s up to the animals to decide whether they want to step inside the device – the equivalent of pressing play – to watch the video of the week, from sealife like fish and jellyfish to wiggly worms and other zoo animals to abstract art and lush forests.
Scientists Use DNA Origami to Monitor CRISPR Gene Targeting
ROCKVILLE, MD – The remarkable genetic scissors called CRISPR/Cas9, the discovery that won the 2020 Nobel Prize in Chemistry, sometimes cut in places that they are not designed to target.

Scientists shed light on 140-year-old challenge in chemistry and physics
In recent research published in the Proceedings of the National Academy of Sciences, Lawrence Livermore National Laboratory (LLNL) researchers Babak Sadigh, Luis Zepeda-Ruiz and Jon Belof report on a new mechanism of solidification in copper that provides an atomistic view of Ostwald’s step rule and alters the fundamental understanding of nucleation at high pressure. They found that not only does the crystallization process proceed via a non-equilibrium phase, but that this phase can be kinetically stabilized by the temperature.
Three Longtime Antibiotics Could Offer Alternative to Addictive Opioid Pain Relievers
DALLAS – Feb. 22, 2021 – Three decades-old antibiotics administered together can block a type of pain triggered by nerve damage in an animal model, UT Southwestern researchers report.

Widely used medications for benign prostatic hyperplasia (BPH) – also known as enlarged prostate – may be associated with a small, but significant increase in the probability of developing heart failure, suggests a study in The Journal of Urology®, Official Journal of the American Urological Association (AUA). The journal is published in the Lippincott portfolio by Wolters Kluwer.
Binary stars are all around us, new map of solar neighborhood shows
The latest star data from the Gaia space observatory has for the first time allowed astronomers to generate a massive 3D atlas of widely separated binary stars within about 3,000 light years of Earth — 1.3 million of them.
Toddler sleep patterns matter
Lauren Covington, assistant professor in the University of Delaware School of Nursing, found that children with inconsistent sleep schedules have higher body mass index (BMI) percentiles. Her research also found that children from households with greater poverty had more overall inconsistent sleep onset times. For families living in poverty, consistent sleep scheduling may not be so easily done, especially if a caregiver is the only parent, juggling multiple jobs, parenting multiple children or dealing with a tenuous housing situation.
Can bacteria make stronger cars, airplanes and armor?

Sleep is vital to associating emotion with memory, according to U-M study
When you slip into sleep, it’s easy to imagine that your brain shuts down, but University of Michigan research suggests that groups of neurons activated during prior learning keep humming, tattooing memories into your brain.
Tricking the novel coronavirus with a fake “handshake”
Fool the novel coronavirus once and it can’t cause infection of cells, new research suggests. Scientists have developed protein fragments that bind to the Spike protein, effectively tricking the virus into “shaking hands” with a replica rather than the receptor that lets the virus into a cell.
‘Jumping genes’ repeatedly form new genes over evolution
A study, “Recurrent Evolution of Vertebrate Transcription Factors by Transposase Capture,” published Feb. 19 in Science, investigates how genetic elements called transposons, or “jumping genes,” are added into the mix during evolution to assemble new genes through exon shuffling.
Antibiotic tolerance study paves way for new treatments
The study in mice, “A Multifaceted Cellular Damage Repair and Prevention Pathway Promotes High Level Tolerance to Beta-lactam Antibiotics,” published Feb. 3 in the journal EMBO Reports, reveals how tolerance occurs, thanks to a system that mitigates iron toxicity in bacteria that have been exposed to penicillin.
Adjusting the Dance Tunes the Melt
Many chemical processes require liquids as solvents, but the liquids often vaporize and release hazardous emissions in the process. Ionic liquids offer a solution because they have low volatility but can have melting points too high for practical use. New research used molecular simulations and experiments to demonstrate how changing the structure of ionic liquids changes their melting point.

New Phenomena for the Design of Future Quantum Devices
Research has shown that the topology of the electronic states in a Weyl semimetal can leave fingerprints on their phonon properties. This happens because of a type of electron-phonon interaction called the Kohn anomaly that impacts how electrons screen phonons through a material. This instability can lead to new electronic properties in materials.
New Artificial Membranes Enable Better Understanding of Membrane Proteins
The cell membrane is the wall-like outer layer consisting primarily of lipids and proteins that separates the inside of a cell from its surrounding environment. Scientists have now used X-ray and neutron scattering techniques to develop a disc-shaped artificial membrane that shows how proteins can exhibit different properties when embedded in membranes with different lipid compositions.
Study suggests COVID-19 pandemic may have led to increased legal cannabis use in at-risk communities
The aim of the current study is to examine whether communities reporting an increased risk for developing mental health issues showed differential patterns of legal cannabis use as the pandemic began. A secondary goal is to examine the feasibility of using anonymized location data to uncover community consumption patterns of potential concern.

Study of auto recalls shows carmakers delay announcements until they can ‘hide in the herd’
Automotive recalls are occurring at record levels, but seem to be announced after inexplicable delays. A research study of 48 years of auto recalls announced in the United States finds carmakers frequently wait to make their announcements until after a competitor issues a recall – even if it is unrelated to similar defects.
