The phrase "the birds and the bees" is a term used to explain the mechanics of reproduction to younger children, relying on the imagery of bees pollinating and eggs hatching to substitute for a more technical explanation of sexual intercourse. It is a way of deflecting the inevitable question that every parent dreads: "Where do babies come from?" and it is an alternative to the explanation that the stork delivers babies.
#Science News
It is uncertain when the phrase was first used or how it gained popularity. It does not necessarily mean that parents are explaining how birds and bees reproduce. The connection between human sexuality and eggs and pollination is vague, which can cause some confusion among curious children.

The tumour-suppressing protein p53 acts as the guardian of the genome by providing important protection against cancer — when it is active, that is. Many malignant cells exhibit p53 dysfunction, and several clinical trials of agents intended to restore p53 to working order are now underway. Nature video | 3 min watch

Organized retail theft, train robberies, and murders! According to news headlines, a crime wave is sweeping the US. Yet as JSTOR Daily has reported before, sometimes crime waves are little more than moral panics. Other times, media coverage does reflect actual increases in crime. To understand the difference, each allegation needs to be carefully dissected and analyzed. |

A Deepening Crisis Forces Physicists to Rethink Structure of Nature’s Laws
By NATALIE WOLCHOVER For three decades, researchers hunted in vain for new elementary particles that would have explained why nature looks the way it does. As physicists confront that failure, they’re reexamining a longstanding assumption: that big stuff consists of smaller stuff.

Grand Finale
An EEG recording of the brain of a man in his last moments of life showed high activity in the centers linked to memory and meditation, Harry Baker reports for Live Science. Maybe our life really does flash before our eyes. This isn’t the only cliché about death with a scientific basis. In 2018 Jennifer Ouellette wrote for Quanta about a mathematical theory for visual hallucinations that explains the “light at the end of the tunnel” reportedly seen by the dying.
Bad Atmosphere
To investigate why Mars lost its magnetic field, researchers modeled a molten core resembling that of the young Mars. They found that convective currents capable of producing magnetic fields were short-lived, Elizabeth Fernandez writes for Big Think. With no magnetic shield, Mars lost its atmosphere to solar winds. In 2019 Rebecca Boyle reported for Quanta that a similar effect could be why there is a dearth of planets 1.5-2 times the size of Earth: When the atmospheres of those planets disappeared, so did much of their mass. |

| | Caros leitores, No último dia do mês de fevereiro foi celebrado o Dia Mundial das Doenças Raras. O número exato de doenças raras não é conhecido, mas estima-se que existam entre 6.000 a 8.000 tipos diferentes em todo o mundo; 80% delas decorrem de fatores genéticos. A presidente do GEDORAC – Grupo de Estudos em Doenças Raras com Acometimento Cardíaco da SBC, Sandra Marques e Silva, fala que há algumas doenças raras que se manifestam principalmente no coração, como a Doença de Fabry.

| Dear Aloyzio, We are pleased to share with you our latest Commission, Time for united action on depression: a Lancet–World Psychiatric Association Commission. The Commission report is free to read with registration on TheLancet.com. Depression is a leading cause of avoidable suffering, globally with an estimated 5% of adults living with the condition. Yet, too few people in communities, governments, and the health sector understand or acknowledge depression as distinct from the other troubles that people face. Not enough is done to avoid and alleviate the suffering and disadvantages linked with depression, and few governments acknowledge the effect of depression on social and economic development. This Commission synthesises evidence from diverse contexts and, in consultation with people with lived experience, generates action-oriented recommendations. Our aim is to promote concerted and united action to reduce the burden of depression and ensure that greater attention is paid to the millions of people who live with it across the globe. We hope you find the Commission to be informative and encourage you to explore the additional resources below. Yours sincerely, Miriam Sabin
Senior Editor, The Lancet |

Human Development Report consultations engage civil society and academia
|
|
Planned for release towards the end of the second quarter of 2022, the upcoming Human Development Report (HDR) engaging partners and stakeholders across disciplines in a series of consultations that will feed into the final report. The latest round of conversations gathered perspectives from civil society and academic experts on "brain capital."
On 21 February, HDRO sought the views and insights of civil society organizations on how institutions and policies can/should be adapted and/or amended to factor today’s uncertainty whilst furthering human development. The consultation featured welcoming remarks from Ulrika Modeer, Assistant Secretary-General, UNDP; and Marina Ponti, Director, SDG Action Campaign, as well as a dynamic panel discussion among civil society leaders.
On 22 February, HDRO and the New Approaches to Economic Challenges (NAEC) initiative at the OECD co-organized a follow-up consultation focusing on the nature of uncertainty and risk today, and how insights from neuroscience and “Brain Capital” advance our understanding of people’s responses to uncertainty and risks. HDRO Director Pedro Conceição was joined by experts on decision-making in the context of uncertainty and neuroscience. |
