Microgel reinforced zwitterionic hydrogel coating for blood-contacting biomedical devices
Nature Communications, Published online: 12 September 2022; doi:10.1038/s41467-022-33081-7 Zwitterionic hydrogels are nonfouling and hemocompatibility but several key challenges such as weak mechanical strength and low adhesion hamper their application as coating materials for devices. Here, the authors report a microgel reinforced zwitterionic hydrogel with excellent mechanical robustness and an
Identification of a binding site on soluble RANKL that can be targeted to inhibit soluble RANK-RANKL interactions and treat osteoporosis
Nature Communications, Published online: 12 September 2022; doi:10.1038/s41467-022-33006-4 Huang et al. discover a binding site on soluble RANKL that is not found on its membrane-bound homologue. A drug screening identified a small molecule (S3-15) that can target this binding site and has anti-osteoporotic but not immunosuppressive effects.
SREBP2-dependent lipid gene transcription enhances the infection of human dendritic cells by Zika virus
Nature Communications, Published online: 12 September 2022; doi:10.1038/s41467-022-33041-1 Zika virus (ZIKV) infection suppresses the induction of dendritic cell (DC)-derived immunity, but the underlying mechanistical insights are still lacking. Here the authors show, using in vitro systems profiling of DC transcriptome and epigenome, that ZIKV specifically alters SREBP2-related expression of inf

It's Time to Prepare for a Ukrainian Victory
Over the past six days, Ukraine's armed forces have broken through the Russian lines in the northeastern corner of the country, swept eastward, and liberated town after town in what had been occupied territory. First Balakliya, then Kupyansk, then Izium, a city that sits on major supply routes. These names won't mean much to a foreign audience, but they are places that have been beyond reach, imp
Study: Four major climate tipping points close to triggering
Even if the world somehow manages to limit future warming to the strictest international temperature goal, four Earth-changing climate "tipping points" are still likely to be triggered with a lot more looming as the planet heats more after that, a new study said.

Young People Are Getting Way More Cancer Than Old People Did
You'd expect that cancer rates would be going down. But tough luck — it looks like that's not the case. Instead, early-onset cancer is an increasing threat to the global population, according to a new report published in the journal Nature Reviews Clinical Oncology this week. "Over the past several decades, the incidence of early-onset cancers, often defined as cancers diagnosed in adults less th
Scientists Are Working on a Gene-Hacking Drug That Could Treat Baldness
Using gene modification techniques, a team of researchers have come up with a new treatment for balding, Wired reports — a condition experienced to varying degrees by two-thirds of American men by age 35 . The team, associated with the University of California, Irvine and a biotech company called Amplifica, believes they've identified the signaling pathway that drive hair growth to find new ways
T cells that 'nibble' tumors unwittingly help cancer evade the immune response
T cells are capable of killing cancer cells, but tumors have tricks to evade their might. New research details one of these strategies, known as trogocytosis, in which T cells ingest a piece of cancer cell membrane, taking on a bit of cancerous identity. Blocking this process could improve the effectiveness of CAR T cell therapy.
Where Our Sense of Self Comes From
W e accept as self-evident that each of us is free to think and form our own opinions, that we have autonomous selves. Western societies and institutions are founded on this spirit of individual freedom and self-determination.

There's Nothing Quite Like the Wrath of Losing Your Fantasy League
At first, Damon DuBois's fantasy-football league kept the punishment for the last-place finisher fairly tame. The loser would have to let the champion select their team name for the following year, take care of the housekeeping at the next draft, or, at worst, sport an I suck at fantasy football license plate all off-season. Nothing crazy. But by the final weeks of each season, league members alr
Mourning rituals help people cope with grief, say scientists
Experts agree on importance of traditions seen after Queen's death in enabling bereaved to process loss The death of Queen Elizabeth II has plunged the royal household and much of the country into a period of mourning, with black armbands and flags at half mast. While such traditions may seem far removed from everyday experiences of bereavement, experts say rituals can help us cope with death. "M
Cloud labs and remote research aren't the future of science – they're here
At high-end labs in the US and UK, anybody, anywhere, can conduct experiments by remote control cheaply and efficiently. Is the rise of the robot researcher now inevitable?

Here, more than 100 items of high-end bioscience equipment whirr away on workbenches largely unmanned, 24 hours a d
After the Queen, What Is Britain?
It wasn't exactly a shock. The ancient and beloved Queen, who had reigned much longer than most of her subjects had lived, was 96 and visibly failing. Leaning on a stick, she managed a smile last week as she invited Liz Truss, Britain's new prime minister, to form a government. And within 48 hours, she was dead. A huge and complex contraption of official mourning, rehearsed to exhaustion over the
Trump Opened Pandora's Prosecutorial Box
One of Donald Trump's biggest effects on American politics has been bringing ideas that used to be considered fringe into the mainstream. Although the most glaring examples include things like election subversion or cozying up to white supremacists, this summer has seen another previously outré idea become more common: prosecuting a former president. For more than two centuries, law-enforcement a
Magpies fly from branch to branch.

The Move to Eradicate Disagreement

How Masking Changed My Experience of Being Deaf
"I' m sorry for participating in the deaf apocalypse." For a hearing friend and me, this line, delivered in sign language, became a running gag early in the pandemic.
