First study shows that foetuses in the womb react to flavours and smells of the mother’s diet

A study led by Durham University’s Fetal and Neonatal Research Lab in the UK has studied, for the first time, the reaction of foetuses to the flavours and smells of the mother’s diet. Foetuses can experience taste and smell through the inhalation and swallowing of amniotic fluid in the womb. Scientists performed 4D ultrasound scans of 100 pregnant women and looked at how the foetuses reacted to carrots or kale - just a few minutes after these were ingested by the mother. It has been observed that foetuses exposed to carrot showed more “laughter-face” responses while those exposed to kale showed more “cry-face” responses. These evidences help to understand the development of our taste and smell and the related perception and memory. Scientists have now begun a follow-up study with the same babies post-birth to see if the influence of flavours they experienced in the womb affects their acceptance of different foods. The same approach is likely to give, in the next future, understanding of what reactions foetuses have to alcohol and smoking, and if these exposures will impact the newborn too. How do foetuses react to mother’s smoking or drinking alcohol? It will be interesting to learn.

Referendums announced to annex 15% of Ukraine to Russia: Putin strengthens mobilisation while Ukraine counteroffensive continues

Yesterday the Russian-installed leaders of four regions of southern and eastern Ukraine - Kherson, Zaporizhzhia, Luhansk, and Donetsk - have reiterated urgent calls for referendums to join Russia, to be held between September 23 and 27. It means around 15% of Ukrainian territory - an area about the size of Hungary or Portugal - would vote on joining Russia similarly to how Russia annexed Crimea in 2014, after a vote that drew international condemnation. Annexing more Ukrainian territory would also enable the Kremlin to claim Russia itself was coming under attack from Nato weapons. This acceleration of events comes shortly after other leaders, at the Shanghai Cooperation Organization (SOC) meeting last week, directly met with Putin. In particular, president of India Modi expressed concern, while president of Turkey Erdogan has recently said convincingly that the Kremlin "wants to end the war as soon as possible". Authorities in Russia have already declared the interest in the legitimacy of the accession referendum procedure, and in their approval by the SCO and BRICS. They also declared that representatives of the media, including foreign ones, will be invited to the referendum, and the regions also requested organisational aid from Russia and other states. This is how Putin justified further mobilisation of Russian troops starting today. On the other hand, president of Ukraine Zelensky declared that "Our positions are not changed by noise and announcements from somewhere, and our partners fully support us on that," promising a continued effort to regain these territories and Crimea. The progress of the counteroffensive means Ukraine could soon launch an assault on Russian forces in the occupied Donbas region.

Natural catastrophic events are happening around the world: a sign of climate change?

In the last months we witnessed natural catastrophic events around the world. More recently, an heavy storm provoked a severe flooding in Italy on September 15, causing deaths and several missed people. On Monday September 19 the typhoon Nanmadol - one of the biggest storm in years - barrelled through southwestern Japan. It killed 4 people and injured more than 100 others. On Sunday 18 hurricane Fiona hit Puerto Rico and the Dominican Republic causing floods. In Italy extreme weather occurred in August, with temperatures peaking at 48.8 Celsius - breaking the European record. In early July, 11 people were killed when a huge mass of ice from a glacier on the north side of the Marmolada mountain in the Dolomites broke away, causing an avalanche. This summer, the Mediterranean sea was five degrees warmer than its average. Record heatwaves this summer were recorded in the whole Northern Hemisphere, with severe droughts in China and central EU. Scientist are currently investigating whether climate change could increase the frequency of these events: as it has been reported that events as hurricane are subject to a number of climate change-related influences, such as warmer sea surface temperatures and sea level rise, a correlation is likely.
