Fluctuations in the hormones secreted by women’s ovaries, namely estrogen and progesterone, are known to cause mood swings. For instance, at different points of the menstrual cycle, during or after pregnancy and while reaching menopause, women can experience lethargy, sadness, irritability, or other emotional changes.

THE Economic Front (EF) has demanded that Government should publish the agreements and conditions which will be signed with the investors for Konkola Copper Mine (KCM) and Mopani Copper Mine.

A new study, “Sensitive poliovirus detection using nested PCR and nanopore sequencing: a prospective validation study,” published 17 August 2023 in Nature Microbiology, proves that using DDNS to detect polio outbreaks can save public health authorities crucial time and money.

THE Media Network Action on Climate Change (MENACC) says government and other stakeholders should beef up dissemination of information on the rainfall patterns for the 2023/2024 farming season to equip to prepare farmers of climatic challenges.

The MENACC says the dissemination of information on rainfall patters should come at the backdrop of climate unpredictability and following warnings of possible below normal rainfall anticipated to affect Southern Africa this farming season.

The World Meteorological Organization (WMO) recently issued alerts of the development of an El Nino climate pattern in the Pacific Ocean this year, which is anticipated to bring dangerously high temperatures and extreme weather events with an 80 per cent chance of an El Niño event developing between July and September and is expected to last for 12 months.

WMO has further indicated that the effects of El Nino climate pattern on global temperatures will likely be most apparent in 2024 with a warning that the world “should prepare” for more extreme weather and climate events, including severe rainfall and drought, depending on the region.

And now, MENACC executive coordinator Kennedy Phiri is concerned over the alert and that there is, therefore need to provide accurate and adequate information to not only farmers but citizens.

Mr Phiri said the country should not lose human lives, infrastructure, crops and domestic animals like cattle due to floods as the case was in the previous rain season especially in Southern Province primarily because of failure to put in place early warning systems and interventions.

Mr Phiri said in the face of climate change, timely distribution of inputs to farmers alone is not enough if not accompanied by the correct information regarding the rainfall partners each season.

To understand the full relationship between brain activity and behavior, scientists have needed a way to map this relationship for all of the neurons across a whole brain—a so far insurmountable challenge. But after inventing new technologies and methods for the purpose, a team of scientists in The Picower Institute for Learning and Memory at MIT has produced a rigorous accounting of the neurons in the tractably tiny brain of a humble C. elegans worm, mapping out how its brain cells encode almost all of its essential behaviors, such as movement and feeding.

Ask any neurologist: Parkinson’s disease is a brain disorder. The conspicuous symptoms of Parkinson’s disease—uncontrollable tremors, slowed down motions, and the feeling that one’s feet are stuck to the ground—all stem from the loss of neurons in a region of the brain that helps control movement.

Most new cancer cases are treated with chemotherapy, but humans naturally express proteins that indiscriminately remove chemotherapy drugs from many cells—including tumor cells, which reduces treatment efficacy.

In a new study published in Nature Cell Biology, researchers used CRISPR/Cas9 in vivo somatic engineering to make mouse models of small cell lung cancer (SCLC) that either expressed KDM6A (KDM6A-WT) or were inactivated for KDM6A (KDM6A-Mutant). KDM6A is an epigenetic modifier that is mutated in human SCLC.

…as Forest Rangers stun Warriors 

By MICHAEL MIYOBA

MIGHTY” Mufulira Wanderers announced their return to the MTN/FAZ Super League with a bang by slaughtering Green Buffalos 1-0 in a Week-1 fixture played yesterday at a fully packed Shinde Stadium in Mufulira. 

A second half goal from Maxwell Mabenga was all the nine-tmes Zambian champions needed to walk away with maximum points in the intriguing match which was tightly contested. 

After a goalless first half, Mabenga stunned Buffaloes with a goal in the 77th minute to send the home fans who had filled Shinde Stadium to capacity into a frenzy. 

Due to the high intensity of the match, both teams finished the game with 10 players after John Kosamu from Buffalos and Wanderers’ defender Bwembya Kakungu were sent off for their clumsy fouls in the second half.  

Meanwhile, Carling Black Label Samuel “Zoom” Ndhlovu Charity Shield winners, Forest Rangers began the new Super League season with an exciting win over Kabwe Warriors. 

Rangers stunned Warriors 1-0 thanks to Lazarous Chishimba’s cracker in the 70th minute. 

Forest had dictated play from the first half and were unfortunate when Moyela Libaba thought he had grabbed the opener two minutes before the break. 

However, the goal was disallowed due to a foul which was committed before the goal. 

It took the Ndola side just 25 minutes of the second half to break the deadlock and score what proved to be the match winner. 

After the impressive win over Warriors, Forest join Zesco United, Red Arrows, and Mufulira Wanderers who all started the new soccer season with 1-0 victories.

Anti-estrogenic therapies can suppress the growth of cancer that does not express estrogen receptors; when combined with immune checkpoint inhibitor therapies, they halt tumor progression in mice models.
