Submitting to Wisdom

“The fear of the Lord is the beginning of wisdom; a good understanding have all those who do His commandments” (Psalm 111:10).

Saving faith is obedient faith.

The wisdom of God resulting from the fear of the Lord leads to obedience. When we fear the Lord, we submit to His wisdom and commit ourselves to keeping His commandments. In the New Testament Jesus said the same thing: “If you love Me, you will keep My commandments” (John 14:15). We aren’t always as obedient as we ought to be, but the pattern of our lives turns from disobedience to a submissive heart of obedience. First John 2:3 says, “By this we know that we have come to know Him, if we keep His commandments.” A person’s claim to be a Christian is meaningless if he’s not obedient.

From a positive perspective, fearing the Lord involves obeying His commandments; from a negative perspective, it involves turning away from evil. Job 28:28 says, “The fear of the Lord, that is wisdom; and to depart from evil is understanding.” Equal to wisdom is understanding, and equal to fearing the Lord is departing from evil. Proverbs 8:13 says, “The fear of the Lord is to hate evil.” Obeying the Lord’s commandments and shunning evil are dynamics that work in the soul of one who truly fears God. The fear of the Lord is not some feeling you try to generate within yourself; it’s the result of believing in the true God and living a life of love and obedience to Him. What about you? Does obedience to God’s Word characterize your life?

Suggestions for Prayer

Jesus Christ paid the price for your sin and ushered you into a relationship with God. Honor His work by obeying His Word, and ask Him to help you see evil from His perspective.

Nations to submit boosted climate plans at COP29: What’s at stake?

Nations have begun setting carbon-cutting targets for the decade ahead, and how ambitious these pledges are could make or break global efforts to avoid dangerous levels of climate change.

Nearly 200 countries are supposed to publish updated climate plans by early February, but so far only three have done so.

On Wednesday, the UK became the latest, announcing during the COP29 climate summit in Azerbaijan that it would raise its target to cut greenhouse gas emissions.

All eyes will be on other big polluters like China, India, and the United States, though future US climate action is unclear following Donald Trump’s election.

Why do they matter?

The world has agreed to try and limit global warming to 1.5 degrees Celsius above pre-industrial levels, but is nowhere near on track.

Above this threshold, scientists say humanity risks disastrous consequences from volatile weather to major ecological “tipping points” at land and sea.

Last month, the United Nations warned that even if all existing plans are implemented in full, temperatures would rise 2.6°C by the century’s end, a catastrophic outcome.

The UN says the next round of climate plans must show a “quantum leap” in ambition to avert the worst.

The G20 — which accounts for 77 per cent of total greenhouse gas emissions — is under particular pressure to step up.

Early movers

Just before COP29 opened in Azerbaijan, the United Arab Emirates announced a 47pc reduction in emissions by 2035 compared with 2019 in its updated climate plan.

Observers said the roadmap failed to account for exported emissions —including those from its sales of crude oil abroad.

Next year’s UN climate host, Brazil, has partly unveiled its plan, increasing its emissions reduction target from a 59pc cut by 2035, from 2005 levels, to a 67pc reduction.

It is expected to unveil a more complete plan during COP29.

Plans from other major emitters, like the European Union and China, are not expected until next year.

And the current US government could soon outline Washington’s new pledge, despite questions over Trump following through once in office.

David Waskow, of the World Resources Institute, said it would help guide American cities, states and businesses wishing to continue climate action under Trump.

“It also sends an important signal internationally, a set of benchmarks for what the US ought to do,” he added.

What do countries need to do?

By signing the Paris accord, nearly 200 nations agreed to halt rising temperatures “well below 2°C” and strive for the safer goal of 1.5°C.

But it did not prescribe how to get there.

The deal left it up to countries to voluntarily chart their own plans and targets, known as Nationally Determined Contributions (NDCs).

These include emission reduction targets and measures to achieve them, such as rolling out renewable energy, electrifying transport, and ending deforestation.

There is no set template for countries to follow but richer countries —historically the largest emitters — have a responsibility to pledge the deepest emission cuts.

The plans must be reviewed every five years, with each update supposed to be more ambitious than the last. This time around countries are expected to improve their 2030 targets and outline economy-wide action they will take to 2035.

What’s the aim?

An agreement at last year’s COP28 climate summit “encouraged” countries to come forward with plans aligned with halting warming to 1.5°C.

To have a hope of meeting that goal, emissions must be slashed 42pc by 2030 and 57pc by 2035, the UN’s Environment Programme said last month.

Currently, however, emissions are continuing to rise.

Keeping 1.5°C on track would require a collective effort “only ever seen following a global conflict”, it added.

Without pulling together “on a scale and pace never seen before… the 1.5°C goal will soon be dead,” said UNEP executive director Inger Andersen.

The big moment for assessing progress towards the 1.5°C goal comes at a crunch COP30 climate summit in Brazil next year.

What about fossil fuels?

Scientists and the International Energy Agency have said that developing new fossil fuel projects is incompatible with halting warming to 1.5°C.

But many fossil fuel-producing countries argue that new oil and gas projects will be needed as the world transitions to net zero emissions.

Countries are under pressure to outline in their updated plans how they intend to reduce their reliance on fossil fuels, something all nations agreed on at last year’s COP.

A summit to nowhere

AFTER silently watching Israel’s genocidal war in Gaza for the past one year, the leaders of the Arab and Muslim countries have once more met in Riyadh to discuss the escalating conflict.

The so-called international alliance conceived by Saudi Arabia, with its aim of pressing for the establishment of a Palestinian state, failed to formulate a concrete plan of action to stop the Israeli invasion that has been extended to Lebanon.

Interestingly, the resolution issued at the conclusion of the joint summit of the Organisation of Islamic Cooperation and Arab League is restricted to the usual condemnation of Israeli aggression. It doesn’t even plainly describe the ongoing Israeli military action in Gaza, which has killed more than 43,000 people, mostly women and children, as a genocide.

There is no suggestion to sever the diplomatic and trade ties with Israel that some of these countries continue to have, despite the war crimes being committed by the Zionist forces. With the complete blockade of the Gaza Strip, more than a million people face death by starvation and disease. Mere condemnation cannot stop Israel’s genocidal war. It is nothing short of a betrayal of the hapless people of Palestine.

In fact, the inaction of the Muslim world has given impunity to the Zionist state, which is now threatening to annihilate the entire occupied territory. The latest summit was held a year after a similar gathering in Riyadh. Then, too, the leaders had merely condemned the Israeli military action in Gaza. They could not agree on even a minimum plan of action to stop Israeli atrocities.

The OIC-Arab League resolution does not go beyond the usual condemnation of Israel.

They did not even leverage their oil and economic capabilities to apply pressure on countries supplying arms to Israel to stop the war. One year of war crimes doesn’t seem to have brought any change in their position, which can be described as capitulation. The resolution is as toothless as the previous one.

The most shocking part of the resolution is the decision “to affirm support and express appreciation for the tireless efforts made by the Arab Republic of Egypt and the State of Qatar in cooperation with the United States of America to achieve an immediate and permanent ceasefire in the Gaza Strip… “. It couldn’t get more outrageous given that the ongoing genocide in Gaza is essentially supported by the US. It is massive American military aid that has helped Israel sustain its war.

Notwithstanding the occasional rebuke by US officials, there has never been any real American pressure on Israel to implement a ceasefire. In fact, the Biden administration has repeatedly vetoed resolutions in the UN calling for one. Some of the Arab rulers are believed to have tacitly supported what Israel has described as its war against Hamas. Moreover, America has its bases in Arab countries, and concerns have been raised that they could have supplied Israel with weapons to kill Palestinians. These countries have not prohibited the use of these bases.

Significantly, the latest summit took place soon after Donald Trump’s victory, which has been hailed by some member countries, prompting observers to conclude that it was meant to send a message to the incoming US administration. It seems that the ‘international alliance’ is now pinning its hopes on the incoming Trump administration to get Israel to agree to a ceasefire and accept the creation of a Palestinian state.

For instance, while addressing a Council of Foreign Ministers preparatory meeting a day before the summit, Pakistan’s Foreign Minister Ishaq Dar expressed the hope that the incoming US administration would “lend its weight to reinvigorate efforts for peace in the Middle East”. His remarks show his utter ignorance about Trump’s hard-line approach to the Middle East conflict.

Such expectations from the president-elect, who is considered even more pro-Israel than the outgoing Biden administration, are unrealistic. During his election campaign, Trump had called on Israel to finish the offensive and “get the job done”. He has stated that he would “defend our friend and ally in the State of Israel like nobody has ever”.

How can one forget that in his previous term he shifted the American embassy to occupied Jerusalem? The move defied Washington’s earlier position of not recognising one of the most sacred of Islam’s holy places as Israel’s capital. In his previous term, Trump had also endorsed Israeli settlements in occupied West Bank, which are illegal under international law. Under the so-called Abraham Accords, he oversaw the establishment of diplomatic relations between Israel, the UAE, Bahrain, and Morocco.

Although Saudi Arabia did not enter into such an agreement, it did indicate its willingness to recognise Israel in return for security and economic benefits, though insisting there would be no diplomatic ties without a Palestinian state. Some analysts believe that the Riyadh summit has sent a clear signal to the incoming Trump administration that it can rely on the kingdom as a strong partner in extending American interests in the region. The summit has pushed for greater American leverage in bringing the war to an end.

But it is very clear that the incoming Trump administration will not push for the establishment of a Palestinian state as envisaged by the ‘international alliance’. There has been no mention of the two-state solution in his recent statements on the Middle East conflict.

Since winning the election, Trump has spoken to the Israeli prime minister more than once. Therefore, it’s not surprising to see the right-wing Israeli government harden its position after Trump’s election.

In a recent statement, Israeli Foreign Minister Gideon Sa’ar opposed the establishment of a Palestinian state, saying it was “unrealistic”. Surely the inaction of the Arab and Muslim countries has made things worse for the Palestinians. The joint resolution indicates that these countries do not have any intention of using their leverage to put pressure on Israel and its allies to end the war.

YY1 knockout in pro-B cells impairs lineage commitment, enabling unusual hematopoietic lineage plasticity [Research Papers]

During B-cell development, cells progress through multiple developmental stages, with the pro-B-cell stage defining commitment to the B-cell lineage. YY1 is a ubiquitous transcription factor that is capable of both activation and repression functions. We found here that knockout of YY1 at the pro-B-cell stage eliminates B lineage commitment. YY1 knockout pro-B cells can generate T lineage cells in vitro using the OP9-DL4 feeder system and in vivo after injection into sublethally irradiated Rag1–/– mice. These T lineage-like cells lose their B lineage transcript profile and gain a T-cell lineage profile. Single-cell RNA-seq experiments showed that as YY1 knockout pro-B cells transition into T lineage cells in vitro, various cell clusters adopt transcript profiles representing a multiplicity of hematopoietic lineages, indicating unusual lineage plasticity. In addition, YY1 KO pro-B cells in vivo can give rise to other hematopoietic lineages in vivo. Evaluation of RNA-seq, scRNA-seq, ChIP-seq, and scATAC-seq data indicates that YY1 controls numerous chromatin-modifying proteins leading to increased accessibility of alternative lineage genes in YY1 knockout pro-B cells. Given the ubiquitous nature of YY1 and its dual activation and repression functions, YY1 may regulate commitment in multiple cell lineages.

FP2020 and FP2030 Country Commitments: A Mixed Method Study of Adolescent and Youth Sexual and Reproductive Health Components

ABSTRACTIntroduction:Family Planning 2020 (FP2020) was established in 2012 with the goal of expanding contraceptive access. By 2020, 46 countries had made commitments to FP2020. A sustained focus on adolescents and youth (AY) began in 2016. During the commitment formulation process, substantial support was offered to countries to develop AY commitments based on sound data, research evidence, and programmatic experience. This study assesses how country commitments under FP2020 and FP2030 have evolved over time with respect to improving attention to and focus on the needs of adolescents and youth sexual and reproductive health (AYSRH).Methods:We analyzed the content of FP2020 and FP2030 country commitments focusing on AY (aged 10–24 years) using a scoring guideline we developed to measure the AY commitments in terms of completeness, clarity, and quality.Results:This analysis shows that FP2030 commitments better articulate strategies and activities to reach AY with contraceptive information and services when compared to FP2020 commitments.Conclusion:FP2030 commitments are stronger in some areas on AYSRH, such as commitment to establish national or local policies, strategies, and guidance for AY programming, specifying the target audience of the AY commitment, and partnering with AY or youth-led organizations in commitments. However, more work remains to be done by countries to dedicate a budget for achieving AY objectives, including measurable targets for monitoring progress, identifying and addressing the root causes that impact AY access to and use of contraception, including child marriage and gender-based violence, and reducing financial barriers to access contraception.

Sensory-Motor Neuropathy in Mfn2 T105M Knock-in Mice and Its Reversal by a Novel Piperine-Derived Mitofusin Activator [Neuropharmacology]

Mitochondrial dysfunction is a hallmark of many genetic neurodegenerative diseases, but therapeutic options to reverse mitochondrial dysfunction are limited. While recent studies support the possibility of improving mitochondrial fusion/fission dynamics and motility to correct mitochondrial dysfunction and resulting neurodegeneration in Charcot-Marie-Tooth disease (CMT) and other neuropathies, the clinical utility of reported compounds and relevance of preclinical models are uncertain. Here, we describe motor and sensory neuron dysfunction characteristic of clinical CMT type 2 A in a CRISPR/Casp-engineered Mfn2 Thr105Met (T105M) mutant knock-in mouse. We further demonstrate that daily oral treatment with a novel mitofusin activator derived from the natural product piperine can reverse these neurologic phenotypes. Piperine derivative 8015 promoted mitochondrial fusion and motility in Mfn2-deficient cells in a mitofusin-dependent manner and reversed mitochondrial dysfunction in cultured fibroblasts and reprogrammed motor neurons from a human CMT2A patient carrying the MFN2 T105M mutation. Like previous mitofusin activators, 8015 exhibited stereospecific functionality, but the more active stereoisomer, 8015-P2, is unique in that it has subnanomolar potency and undergoes entero-hepatic recirculation which extends its in vivo half-life. Daily administration of 8015-P2 to Mfn2 T105M knock-in mice for 6 weeks normalized neuromuscular and sensory dysfunction and corrected histological/ultrastructural neurodegeneration and neurogenic myoatrophy. These studies describe a more clinically relevant mouse model of CMT2A and an improved mitofusin activator derived from piperine. We posit that 8015-P2 and other piperine derivatives may benefit CMT2A or other neurodegenerative conditions wherein mitochondrial dysdynamism plays a contributory role.

SIGNIFICANCE STATEMENT

Mitochondrial dysfunction is widespread and broadly contributory in neurodegeneration, but difficult to target therapeutically. Here, we describe 8015-P2, a new small molecule mitofusin activator with ~10-fold greater potency and improved in vivo pharmacokinetics versus comparators, and demonstrate its rapid reversal of sensory and motor neuron dysfunction in an Mfn2 T105M knock-in mouse model of Charcot-Marie-Tooth disease type 2 A. These findings further support the therapeutic approach of targeting mitochondrial dysdynamism in neurodegeneration.
