Pressure from individual particles measured for the first time

Pressure from individual particles measured for the first time

The ultra-sensitive pressure sensor features a 100-nanometre silica sphere held in place by laser light Thomas Penny/Yale Wright Laboratory The pressure produced by a single particle can now be measured for the first time, thanks to a device that uses a tiny bead held in place by a laser. It is so sensitive that researchers hope that it could help find elusive new particles, such as those that could make up dark matter. Pressure is caused by particles hitting an object and collectively exerting a force across its area. Researchers typically think of it as an average effect rather than zooming in on each particle, but when pressure is extremely low, such as in experiments conducted in near-perfect vacuum, tracking every particle is needed to properly account for its effects. Yu-Han Tseng at Yale University and his colleagues have now built the first device capable of making such measurements. The central component is a tiny silica sphere, half the size of some viruses, held in place with a laser beam thanks to electromagnetic interactions between …

How individual consciousness works – and makes us unique

How individual consciousness works – and makes us unique

As we go through life, our brains run different processing modes. Some – the attention and sensory systems – result in very similar experiences of the world: what colour the sky is, how warm the day feels. But there is another, deeper side to the brain which weaves together your memories, goals, beliefs and emotions into a continuous sense of self. This allows you to experience the world not as it is, but as it matters to you personally. This unique inner world is supported by the brain’s default mode network (DMN). This links together several areas including in the prefrontal cortex (at the very front of the brain) and the parietal lobe (at the back). These areas of the DMN are, in evolutionary terms, relatively recent. As human brains expanded dramatically between around 800,000 and 200,000 years ago, those regions grew in size and complexity compared with our closest primate relatives. They are more likely to express genes that are uniquely human, related to brain development and function. Our latest research explores to what …

How parent-child political disagreements harm relationships and individual mental health

How parent-child political disagreements harm relationships and individual mental health

A recent study published in the Journal of Social and Personal Relationships suggests that political disagreements within families can harm relational and individual mental health by breaking down positive communication. The research provides evidence that maintaining open and respectful dialogue is necessary to protect family bonds and personal well-being when relatives hold conflicting political or moral views. Political polarization often transforms everyday decisions into highly charged emotional and moral conflicts. In regions experiencing intense political division, mundane choices like where to shop or eat can become politicized and create ongoing stress within families. Much of the previous research on family political conflict has focused on strict binary divides, such as liberals opposing conservatives or pro-government supporters opposing anti-government activists. Yet, in highly polarized environments, political neutrality is not always seen as a peaceful middle ground. People who identify as neutral often hold strong views that criticize both sides, or they may be viewed by politically active family members as failing to take a stand against injustice. “The motivation for this study stems from the long-standing …

This mental trait predicts individual differences in kissing preferences

This mental trait predicts individual differences in kissing preferences

A new study published in Sexual and Relationship Therapy provides evidence that a person’s tendency to engage in sexual fantasy influences what they prioritize in a romantic kiss. The findings suggest that the mental act of imagining intimate scenarios is strongly linked to placing a higher value on physical arousal and contact during kissing. This research helps explain the psychological connection between cognitive states and physical intimacy. From an evolutionary perspective, researchers have proposed three main reasons for romantic kissing. The first is “mate assessment,” which means kissing helps individuals subconsciously judge a potential partner’s health and genetic compatibility. The second is “pair bonding,” where kissing serves to maintain an emotional connection and commitment between partners in a long-term relationship. The third proposed function is the “arousal hypothesis.” This theory suggests that the primary biological purpose of kissing is to initiate sexual arousal and prepare the body for intercourse. While this seems intuitive, previous scientific attempts to prove this hypothesis have failed to find a strong link. Past data did not show that kissing consistently …

What It Means to Do Relational Work With Individual Clients

What It Means to Do Relational Work With Individual Clients

What does it mean to do relational work with individual clients? It might sound contradictory, but it’s actually one of my very favorite ways to work — and it has the potential to resolve some serious issues that individual therapists often face. Many of our clients come to us for help with issues they’re experiencing in their relationships, whether with their spouses, their family members, their friends, or their colleagues. As therapists, we can ask questions about dynamics, offer support, and reflect back what we see, but we’re only getting part of the picture. Our understanding is limited by our client’s willingness to share and their level of insight. That, in turn, limits how much we can help. This knowledge gap can lead to all kinds of issues. For instance, based on our client’s reporting, we may end up seeing the client’s partner as a villain — while if we were to actually see how things play out, we might discover that our client contributes to unhelpful relationship dynamics. (This is a common refrain among …

FBI release ‘terrifying’ new footage in Nancy Guthrie case of ‘armed individual’ at her house morning of disappearance

FBI release ‘terrifying’ new footage in Nancy Guthrie case of ‘armed individual’ at her house morning of disappearance

A new update in the search for Savannah Guthrie’s mom Nancy Guthrie has proved chilling for many netizens. On February 10, the FBI released new images in connection with the case, allegedly taken by surveillance cameras outside the home. The black and white images show a masked figure outside the home, with some of them seeming to suggest tampering with the cameras. The newly released pictures from a Nest camera connect to the FBI and the Pima County Sheriff Department’s previous assertion that the surveillance footage outside the home was lost in the wee hours of the morning after the cameras were damaged. © InstagramNew images have been released from the FBI in connection with Nancy Guthrie’s disappearance FBI Director Kash Patel shared in a statement: “New images in the search for Nancy Guthrie,” sharing further details about the ongoing search for Nancy, 84. “Over the last eight days, the FBI and Pima County Sheriff’s Department have been working closely with our private sector partners to continue to recover any images or video footage from …

Scientists use atomic switches to reliably connect individual molecules to electrodes

Scientists use atomic switches to reliably connect individual molecules to electrodes

Electronics keep shrinking, but silicon is starting to run into physical limits. To go smaller, researchers are turning to something far tinier than any transistor on a chip: single molecules that act as circuit elements in their own right. One of the biggest roadblocks has been surprisingly simple to state and very hard to solve. How do you make a clean, stable electrical connection between a single molecule and metal electrodes so those tiny parts can work together as a real circuit for you to use? Cracking the Wiring Problem At the Molecular Scale A team in Japan has now taken a major step toward that goal. Researchers at the Institute of Science Tokyo and partner institutes have built silver based atomic switches that can reliably connect individual molecules to electrodes in a solid device. Their work shows how to build and break metal filaments one atom thick, then let a single molecule slip into that gap and carry current. This sounds abstract, but the goal is concrete. If engineers can wire up molecules in …
