When Abigail Marsh was 19, a complete stranger risked his life to save her from a car accident. Today, she studies what motivates us to help others — and why some of us are "extraordinary" altruists.
Freedom from suffering is not only possible, but the means for achieving it are immediately within our grasp—literally as close to us as our own breath. This is the 2,500-year-old good news contained in the Anapanasati Sutra , the Buddha's teaching on cultivating both tranquility and deep insight through full awareness of breathing. In this book, Larry Rosenberg brings this timeless meditation method to life. Using the insights gained from his many years of practice and teaching, he makes insight meditation practice accessible to modern practitioners.

At the prison where Cheryl Steed works, certain inmates are chosen to be caregivers for elderly inmates. The program has made her wonder — can altruism be learned?
An individual has a theory of mind if he imputes mental states to himself and others. A system of inferences of this kind is properly viewed as a theory because such states are not directly observable, and the system can be used to make predictions about the behavior of others. As to the mental states the chimpanzee may infer, consider those inferred by our own species, for example, purpose or intention, as well as knowledge, belief, thinking, doubt, guessing, pretending, liking, and so forth. To determine whether or not the chimpanzee infers states of this kind, we showed an adult chimpanzee a series of videotaped scenes of a human actor struggling with a variety of problems. Some problems were simple, involving inaccessible food – bananas vertically or horizontally out of reach, behind a box, and so forth – as in the original Kohler problems; others were more complex, involving an actor unable to extricate himself from a locked cage, shivering because of a malfunctioning heater, or unable to play a phonograph because it was unplugged. With each videotape the chimpanzee was given several photographs, one a solution to the problem, such as a stick for the inaccessible bananas, a key for the locked up actor, a lit wick for the malfunctioning heater. The chimpanzee's consistent choice of the correct photographs can be understood by assuming that the animal recognized the videotape as representing a problem, understood the actor's purpose, and chose alternatives compatible with that purpose.
Cognitive impairment represents a significant source of disability among individuals with schizophrenia. Therefore, the aim of this study was to investigate, at a proof-of-concept level, whether one single bout of exercise can improve executive function among these individuals. In this within-participant, counterbalanced experiment, participants with schizophrenia (n=36) completed two sessions (cycling at moderate-intensity and passively sitting) for 20 min, with a one-week washout period between the two sessions. Participants completed the Wisconsin Card Sorting Test (WCST) before and after each session to measure changes in executive function. The inclusion of both sessions completed by each participant in the analyses revealed a significant carryover effect. Consequently, only the WCST scores from the first session completed by each participant was analyzed. There was a significant time by session interaction effect for non-perseverative errors. Post-hoc Tukey's HSD contrasts revealed a significant reduction in non-perseverative errors in the exercise group that was of moderate-to-large effect. Furthermore, there was also a moderate between-group difference at post testing. Therefore, an acute bout of exercise can improve performance on an executive function task in individuals with schizophrenia. Specifically, the reduction in non-perseverative errors on the WCST may reflect improved attention, inhibition and overall working memory.
Philosopher Peter Singer's work focuses on "effective altruism" — how to do the most good to make the world a better place. He argues effective giving involves balancing empathy with reason.
Larissa MacFarquhar writes about extreme altruists, people who make great sacrifices to help others. She says most of us aren't prepared or willing to do that — which is why we don't give more.
Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world’s vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds, and amphibians move one category closer to extinction each year. However, this overall pattern conceals the impact of conservation successes, and we show that the rate of deterioration would have been at least one-fifth again as much in the absence of these. Nonetheless, current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups: agricultural expansion, logging, overexploitation, and invasive alien species.Though the threat of extinction is increasing, overall declines would have been worse in the absence of conservation.

Ecosystem services have become a mainstream concept for the expression of values assigned by people to various functions of ecosystems. Even though the introduction of the concept has initiated a vast amount of research, progress in using this knowledge for sustainable resource use remains insufficient. We see a need to broaden the scope of research to answer three key questions that we believe will improve incorporation of ecosystem service research into decision-making for the sustainable use of natural resources to improve human well-being: (i) how are ecosystem services co-produced by social–ecological systems, (ii) who benefits from the provision of ecosystem services, and (iii) what are the best practices for the governance of ecosystem services? Here, we present these key questions, the rationale behind them, and their related scientific challenges in a globally coordinated research programme aimed towards improving sustainable ecosystem management. These questions will frame the activities of ecoSERVICES, formerly a DIVERSITAS project and now a project of Future Earth, in its role as a platform to foster global coordination of multidisciplinary sustainability science through the lens of ecosystem services.
The authors asked breast cancer (BC) patients to participate in 1 of 3 mind-body interventions (cognitive-behavioral therapy (CBT), yoga, or self-hypnosis) to explore their feasibility, ease of compliance, and impact on the participants' distress, quality of life (QoL), sleep, and mental adjustment. Ninety-nine patients completed an intervention (CBT: n = 10; yoga: n = 21; and self-hypnosis: n = 68). Results showed high feasibility and high compliance. After the interventions, there was no significant effect in the CBT group but significant positive effects on distress in the yoga and self-hypnosis groups, and, also, on QoL, sleep, and mental adjustment in the self-hypnosis group. In conclusion, mind-body interventions can decrease distress in BC patients, but RCTs are needed to confirm these findings.
Background: Increasingly, bipolar disorder is being treated with maintenance combinations of medication and psychotherapy. We examined the feasibility and benefits associated with an 8-week mindfulness-based cognitive therapy (MBCT) class for bipolar patients who were between episodes. Participants (N = 22; mean age, 40.6 yrs; 14 bipolar I, 8 bipolar II) were existing patients in outpatient clinics at Oxford University (n = 14) or the University of Colorado, Boulder (n = 8), most undergoing pharmacotherapy with mood stabilizers and/or atypical antipsychotic agents. Patients underwent a pretreatment assessment of symptoms and then received the 8-week MBCT in four separate groups, two at each site. MBCT consisted of mindfulness meditation strategies and traditional cognitive-behavioral techniques to address the mode in which negative thoughts and feelings and emerging manic symptoms are processed. We examined within-group changes from pre- to posttreatment in the four aggregated groups. Of the 22 patients, 16 (72.7%) completed the groups. Reductions were observed in depressive symptoms and suicidal ideation, and to a lesser extent, manic symptoms and anxiety. A case study illustrating the effects of MBCT is given. In conclusion, MBCT is a promising treatment alternative for bipolar disorder, particularly for managing subsyndromal depressive symptoms. There is a need for larger-scale randomized trials that examine the cost-effectiveness and relapse-prevention potential of this modality.
<p>Neurophysiological and psychological evidence require us to see perception, the 'fabrication of (conscious) experience', as a process in time. Some of the elapsed time between the onset of stimulation and the appearance of a conscious image is accounted for by considerations of neural hardware. Cognitive science conventionally assumes that these structural factors are sufficient to account for the delay. However I argue in this paper that the human information processing system may interpose an additional strategic delay that allows for processes of checking and editing the developing `sketch' or `draft', so that elements that might threaten an underlying self system can be massaged or deleted. This cognitive model parallels that which is found in the Buddhist Abhidhamma, and improves upon the traditional, canonical formulation. Mindfulness meditation can be seen as a process of `attentional retraining', in which the strategic delay is reduced through practice, and self-related assumptions, which had previously been dissolved in or pre-supposed by conscious experience, become crystallized out and capable of being problematized.</p>
