Hibernation Slows Biological Aging in Bats, UMD-led Study Finds


The most typical bat in the USA, the large brown bat, boasts an unusually lengthy lifespan of as much as 19 years. A brand new research led by College of Maryland researchers identifies one of many secrets and techniques to this bat’s distinctive longevity: hibernation.

“Hibernators are inclined to live longer than migrators,” mentioned the research’s senior writer, UMD Biology Professor Gerald Wilkinson. “We knew that, however we didn’t know if we’d detect modifications in epigenetic age attributable to hibernation.”

The researchers decided that hibernating over one winter extends an enormous brown bat’s epigenetic clock—a organic marker of getting older—by three-quarters of a yr. The research, revealed in the present day within the journal Proceedings of the Royal Society B, additionally included scientists from McMaster College and the College of Waterloo, each in Ontario, Canada.

They analyzed small tissue samples taken from the wings of 20 massive brown bats (Eptesicus fuscus) ranging in age from lower than 1 yr outdated to greater than 10 years outdated in the course of the winter after they hibernated and in the summertime after they had been lively.

The researchers measured modifications in DNA methylation—a organic course of related to gene regulation—between samples taken from the identical animal throughout lively and hibernating durations. They found that modifications in DNA methylation occurred at sure websites within the bat’s genome, and these websites seemed to be affecting metabolism throughout hibernation.

“It’s fairly clear that the websites that lower methylation within the winter are those that seem like having an lively impact,” Wilkinson mentioned. “Lots of the genes which can be nearest to them are identified to be concerned in regulating metabolism, in order that they presumably preserve metabolism down.”

A few of these genes are the identical ones that Wilkinson and fellow researchers recognized as “longevity genes” in a earlier research.

Michigan State football opens as sizable underdog vs Maryland

Michigan State football opens as sizable underdog vs Maryland


Who’s ready for Big Ten play to begin? In all honesty, I am not. I really wish Michigan State football had more tune-up games after seeing them struggle against Florida Atlantic and only win 16-10. But unfortunately, that is not how the schedule unfolds for Michigan State this season.

The Spartans will hit the road for an early Big Ten game as they face Maryland on Saturday at 3:30 pm. Going into the season I thought Michigan State and the Terps were on a pretty level playing field, but after seeing both teams play week one that doesn’t appear to be the case.

And Vegas agrees.

As you all know, Michigan State only beat Florida Atlantic by six and did not look very impressive, especially on the offensive side of the ball. So it’s no surprise that MSU will be the underdog next week. But 7.5 points feels like a lot, and according to the Lansing State Journal’s Graham Couch, it likely will only go up from there.

So does Vegas have it right or are they underrating Michigan State?

Looking at Maryland’s week one game against UConn it appears Vegas has this line right. The Terps were up 23-0 at halftime and never looked back and went on to win in dominant fashion 50-7. UConn and FAU are very similar in terms of what level they’re at in college football, so that drastic of a difference in the final score is very scary.

So Vegas probably could’ve gotten away with Maryland being even bigger favorites in this one.

But maybe Vegas saw what I did and thinks a lot of Michigan State’s mistakes on Friday are easy to fix. Maybe they think Aidan Chiles will be much better next week. The Spartan’s defense was also fairly dominant so there isn’t much of a chance Maryland scores 50 points next week either.

I tend to not bet on Michigan State games, but even if I did this would be a line that I would avoid because who knows how much Jonathan Smith’s squad will improve by next week, and who knows how much Maryland might struggle against a Power Four opponent.

University of Maryland reverses decision to allow anti-Israel protest on October 7


The University of Maryland on Sunday reversed its decision to allow an anti-Israel protest on the first anniversary of the October 7 Massacre, following backlash from local Jewish groups. 

UMD Students for Justice in Palestine and UMD Jewish Voice for Peace had been set to hold their October 7 vigil for Gazans killed in the Israel-Hamas War at the campus’s Mckeldin Mall, but the University System of Maryland (USM) said in a statement that on the day of the Hamas-led pogrom it would limit campus events requiring permits or approval to those supporting “a university-sponsored Day of Dialogue.”

“From the beginning of the war, we have come together as a University System to urge that we use this moment to encourage conversation, compassion, and civility; to engage with one another across our differences and draw on our shared humanity and our shared values to bridge what divides us,” said USM. “These dialogues aren’t new. Many of our universities have been hosting this kind of programming for several months. Reserving Oct. 7 gives us a chance to continue these urgent conversations and to mark this solemn anniversary in a way that gives students—all students—the time and space to share and to be heard.”

USM said that its intent was not to infringe of the free expression and speech of students, but to be sensitive to the needs of students as October 7 was a “day of enormous suffering and grief for many in our campus communities.”

UMD Jewish Student Union, Maryland Hillel, Terps for Israel, and Israeli American Council Mishelanu at Maryland welcomed the USM decision and thanked UMD leadership in a joint social media statement on Sunday.

“October 7, the largest massacre of Jews since the Holocaust, is a day of mourning for the Jewish and Israeli community,” said the UMD JSU. “We are relieved that SJP will no longer to be able to appropriate the suffering of our family and friends to fit their false and dangerous narrative.”

The Jewish groups said that it was distraught that the decision to only hold university-sponsored event had to be made at all, and wished to used the campus space to “grieve together as a community” to promote unity at the university. The unideal situation was necessary, according to the Jewish groups, to ensure the physical and psychological safety of students on the day of mourning.

UMD JVP and SJP attacked the decision to cancel the event, claiming that the vigil for Palestinians killed since the October 7 Massacre was attacked without familiarity of the content. The anti-Israel groups said that the discourse was “the continuation inherently racist, Islamophobic, and dehumanizing rhetoric surrounding Palestinians.” JVP and SJP said that the actions against their event were an attempt to paint “Muslim, Arab, and anti-Zionist Jewish students as barbaric.”

The anti-Israel groups asserted that their vigil for Palestinians who died in the war was no threat to the campus’s Jewish community, but conflation of Zionism and Judaism did threaten UMD and the Jewish community. 

“To claim that Palestinians cannot hold a day of remembrance in mourning one year of genocide, or lay claim to that date is an insult to every life lost in the Zionist entity’s genocidal campaign,” UMD SJP and JVP said on Instagram on Sunday. “The disproportionate scale of suffering experienced by the Palestinians over the past year necessitates their remembrance and our solidarity on this day. The suffering of all innocents killed must not be monopolized and necessitates a fair and just representation.”

The organizations indicated on their Sunday Instagram post that they still planned to hold their all-day event at Mckeldin Mall, and on Monday a link to register still active and listing the campus building as the rally location. 

UMD Jewish groups said that they would be holding their own event to memorialize the victims of the October 7 pogrom at the Maryland Hillel.
