Weight loss may 'rejuvenate' fat tissue in the body

Despite decades of research focusing on obesity, what happens in the body when we lose weight, and why losing weight can improve health, is still poorly understood.Now a new study, published in Nature on Wednesday (July 9), provides clues as to what may actually be happening. It suggests that the weight loss does more than shave off pounds — it changes fat on a cellular level, rewiring how the tissue is metabolized and maybe even "rejuvenating" it.The research also offers insights into why losin...

Promising migraine treatment may work with completely 'new mechanism'

Ozempic-like drugs used to treat type 2 diabetes and obesity may also treat migraine, even when the medications don't trigger weight loss, early research suggests.A preliminary report, published in the journal Headache and presented June 21 at the European Academy of Neurology (EAN) conference, suggests that liraglutide — a drug used to treat obesity and diabetes — slashed the number of days patients experienced severe migraines by almost half. Liraglutide belongs to a class of drugs called GLP-...

The brain might have a hidden 'off switch' for binge drinking

The brain might have a hidden "off switch" for binge drinking, and it seems to be governed by fewer than 500 brain cells, new research suggests.The study, published June 10 in the journal Nature Neuroscience, found that in mice, activating or blocking this unique cluster of brain cells, or neurons, can suppress or unleash binge drinking.If the same "off switch" can be found in humans, this tiny neural circuit could become a new target for the treatment of alcohol use disorder."What we have learn...

"Supporting Science, Acting for a Sustainable Ocean" : the AXA Research Fund launches latest publication in conjunction with the United Nations Ocean Conference 2025

Copywriting, editing, and factchecking texts presenting work supported by AXA Research Fund fellows for the  "Supporting Science, Acting for a Sustainable Ocean" report, timed to release alongside the United Nations Ocean Conference (UNOC) 2025 taking place in Nice, France from 9 to 13 June 2025, and the One Ocean Science Days from 3 to 6 June 2025.

Can weight loss drugs help you drink less alcohol?

Anecdotal reports suggest that people who are taking weight loss drugs like Ozempic and Wegovy say they suddenly find it easier to turn down an extra drink on a night out. But does research align with these stories? Do these weight loss drugs cause people to reduce their alcohol consumption?Although more research is needed, evidence is mounting that GLP-1 receptor agonists — a class of drugs that includes semaglutide (brand names Ozempic and Wegovy) and liraglutide (Saxenda) — do seem to reduce...

Why and how to write an opinion piece - Agent Majeur

Copywriting a blog post promiting a training on Opinion Writing for comms agency Agent Majeur --- Climate change, artificial intelligence, pandemics, space technologies… At a time when these issues are making headlines, the world needs grounded experts who can help make sense of research. For a researcher, sharing scientific results in academic publications remains fundamental, but more can be done to reach a broad audience and initiate concrete change. Writing an opinion piece is much more than sharing your expertise: it’s about captivating the imagination, raising awareness, and sometimes...

India's transition to electric vehicles

Peter Wells. India as a whole has done pret­ty well in adopt­ing elec­tric vehi­cles, but there’s plen­ty of scope to do more. The coun­try acknowl­edged ear­ly on that there were oppor­tu­ni­ties for gain with the tran­si­tion, notably when it comes to reduc­ing the health effects of air pol­lu­tion and noise. Accord­ing­ly, they have been sup­port­ing this change since 2015, notably with the Faster Adop­tion and Man­u­fac­tur­ing of Hybrid and Elec­tric Vehi­cles (FAME) sub­sidy scheme that su...

Man nearly guaranteed to get early Alzheimer's is still disease-free in his 70s — how?

A man whose genetics almost guaranteed that he would develop Alzheimer's disease by his 50s has somehow made it to his mid-70s with nary a symptom.The now-75-year-old man, Doug Whitney, is one of only three people known to have escaped their genetic fate, sidestepping a rare form of Alzheimer's disease called dominantly inherited Alzheimer's disease (DIAD). Caused by several gene mutations, DIAD makes up less than 1% of all Alzheimer's cases, and its symptoms typically set in between ages 35 and...

People who can't 'see with their mind's eye' have different wiring in the brain

People with aphantasia lack the ability to summon crisp images in their "mind's eye." But even though they can't visualize in this way, the blueprints for those imaginary images might still be nestled in their brains, a new study suggests.The work, published in the journal Current Biology Jan. 10, provides early evidence that the brains of people with aphantasia can light up as if they were generating mental images in their primary visual cortex — the main part of the brain responsible for proce...

Sperm cells carry traces of childhood stress, epigenetic study finds

Fathers may carry traces of their childhood trauma in their sperm cells, a new study finds.The new research, published Jan. 3 in the journal Molecular Psychiatry, looked at the "epigenetics" of the sperm cells of fathers who had been exposed to high stress in childhood.Epigenetics involves how DNA — the blueprint used to build the proteins and molecules that make up our bodies — is read. Epigenetics doesn't change DNA's underlying code but rather alters which genes can be switched on. Research s...

Can quantum computing crack the biggest challenges in health? - Nature Medicine

Cleveland Clinic in the USA and the
UK National Health Service are both part of a burgeoning community of researchers, health systems and companies exploring applications of quantum computing in health. Although this nascent technology is at least a few years away from having practical applications — and some are warning of the
impending burst of the ‘quantum bubble’ —
many experts believe that biomedical and
healthcare research needs to be ready for the
quantum revolution of tomorrow.
“I know we are taking a gamble,” says
Lara Jehi, Cleveland Clinic’s chief research
information officer, who leads the institute’s
quantum research. Jehi hopes that “there is a
strategic, long-term advantage in being the
group that was first.”

A powerful solar storm is due to hit Earth on New Year's Eve, sparking beautiful auroras. Here's how to see them.

A pair of powerful geomagnetic storms are due to strike Earth on Tuesday and Wednesday, causing dazzling auroras across the planet which may be seen farther south than usual.The coming auroras have been predicted after the sun recently released some plasma during two coronal mass ejections that are currently traveling toward us at breakneck speeds.The National Oceanic and Atmospheric Administration predicts the first wave of plasma will reach the Earth on Tuesday, exciting our outer atmosphere a...

European Commissioner Olivér Várhelyi speaks at Brussels - EP, Brussels - European Parliament

New EU Health Commissioner appointed amid controversy

Olivér Várhelyi's tempestuous confirmation process has seen pandemic preparedness and reproductive health stripped from his portfolio. Marianne Guenot reports.
Europe has a new Commissioner for Health and Animal Welfare. Olivér Várhelyi, the former European Commissioner for Neighbourhood and Enlargement, began his term on Dec 1, as part of European Commission President Ursula von der Leyen's second College of Commissioners.
The new role for Hungary's Várhelyi was among the most disputed, with Members of the European Parliament (MEPs) raising his connection to President Viktor Orbán and the controversial right-wing Fidesz party during his confirmation. Negotiations eventually led to sexual and reproductive health and pandemic preparedness being stripped from Várhelyi's portfolio.

How AI could humanise robots - Polytechnique Insights

Watch­ing videos released by robot­ics com­pa­nies like Tes­la and Fig­ure, it could seem like robots will walk into our homes tomor­row, able to exe­cute any com­mand a human asks them to do thanks to advance­ments in large lan­guage mod­els (LLMs). That may be com­ing down the pike, but there are some sub­stan­tial hur­dles to over­come first, says Edward Johns, direc­tor of the Robot Learn­ing Lab at Impe­r­i­al Col­lege London.

'Tour de force' study may explain why trauma can lead to PTSD

Intense stress can lead to fuzzy memories, which can lead to more generalized fear responses. Now, scientists may have just discovered why.A study in mice, published Friday (Nov. 15) in the journal Cell, suggests that stress hormones can distort how memories are recorded, leading to less-precise recollections and a future tendency to be unable to properly distinguish between safe triggers and threats.The new findings could help uncover new avenues to treat people with post-traumatic stress disor...
