At a press conference on the shores of Loch Ness, Scotland, DNA scientist Neil Gemmel announced the results of his year-long analysis of what creatures lurk beneath the mysterious seas. NBC’s Kelly Cobiella reports for TODAY.

LONDON, Sept 5 (Reuters) – Scotland’s fabled Loch Ness monster could possibly be a giant eel, scientists said on Thursday after an intensive analysis of traces of DNA in the Loch’s icy waters.Source: Loch Ness monster might just be a giant eel, say scientists
The results ruled out the presence of large animals such as dinosaurs, they said.
But there was a lot of eel DNA in the Loch, Professor Neil Gemmell, a geneticist from New Zealand’s University of Otago, told reporters.
“Eels are very plentiful in the loch system – every single sampling site that we went to pretty much had eels and the sheer volume of it was a bit of a surprise,” Gemmell said.
“We can’t exclude the possibility that there’s a giant eel in Loch Ness but we don’t know whether these samples we’ve collected are from a giant beast or just an ordinary one – so there’s still this element of ‘we just don’t know.'”
A genetic analysis of almost half a million people has concluded there is no single “gay gene”.
The study, published in Science, used data from the UK Biobank and 23andMe, and found some genetic variants associated with same-sex relationships.
But genetic factors accounted for, at most, 25% of same-sex behaviour.
Advocacy group GLAAD said the study confirmed “no conclusive degree to which nature or nurture influenced how a gay or lesbian person behaves.”

WASHINGTON — Scientists with the Smithsonian have discovered a new blood-sucker in the D.C. area — a previously unknown species of leech that has three jaws with up to 59 teeth.
The scientists with the Smithsonian recently published a paper in the Journal of Parasitology documenting their discovery of the leech, or Macrobdella mimicus. They said the leech is the first to be discovered on the content in over 40 years.

Scientists at NASA have just backed Andrew Yang on his dark but realistic climate change response from the second Democratic debate weeks ago.
Immediately after the debate political pundits criticized the presidential candidate for saying that people should start moving away from the coast since it will only get warmer in a few years no matter how well we do on curbing emissions.
“The important number in this is 15 percent of global emissions,” said Yang. “We like to act as if we’re 100 percent. Even if we were to curb our emissions dramatically, the Earth is going to get warmer. The last four years have been the four warmest years in history. We are too late. We are 10 years too late.”

NPR visited the only lab in the world known to be trying to use the powerful gene-editing tool CRISPR to modify the DNA in human sperm. If successful, it could be used to prevent genetic disorders.
First it was human embryos. Now scientists are trying to develop another way to modify human DNA that can be passed on to future generations, NPR has learned.
Reproductive biologists at Weill Cornell Medicine in New York City are attempting to use the powerful gene-editing technique called CRISPR to alter genes in human sperm. NPR got exclusive access to watch the controversial experiments underway.
The research is aimed at finding new ways to prevent disorders caused by genetic mutations that are passed down from men — including some forms of male infertility. The team is starting with a gene that can increase the risk for breast, ovarian, prostate and other cancers.
